Understanding the charactersitics and types of single-person households based on food purchase frequencies in Korea: a cross-sectional study using the 2023 Consumer Behavior Survey for Foods: So-Yun Kim, Youngmin Nam, Jong-Youn Rha, Haerang Lee; Korean J Community Nutr 2025;30(1):27-39. Published online February 28, 2025; DOI: https://doi.org/10.5720/kjcn.2025.00031

Abstract PDF PubReader ePub: Objectives
This study investigated the differences in food purchase frequency among single-person households by gender and age group and explored the characteristics of single-person household groups according to their food purchase patterns.
Methods
Utilizing data from the 2023 Consumer Behavior Survey for Foods conducted by the Korea Rural Economic Institute, this study examined food purchase frequencies among 966 single-person households. Data were analyzed using Rao-Scott chi-square tests, ANCOVA, ANOVA, and K-modes hierarchical cluster analysis.
Results
Significant differences were observed in the food purchase frequencies of single-person households for fresh and convenient food. Women displayed higher purchase frequencies for fish, vegetables, and fruits, whereas men showed higher purchase frequencies for convenient foods (P < 0.005). Single-person households aged 39 years and younger exhibited lower purchase frequencies for vegetables (P < 0.005) and fish (P < 0.001) and substantially higher frequencies of convenient food purchases (P < 0.001). Additionally, this study identified three distinct single-person household groups based on food purchase pattern: the “nutrition-conscious” group, which exhibited high purchase frequency for fresh foods; the “convenience-seeking” group, which showed high purchase frequency for all types of convenient foods; and the “passive food consumer” group, which displayed relatively low purchase frequency for both fresh foods and convenient foods. The socio-demographic characteristics of single-person households differed significantly across these three groups, with the “passive food consumer” group and “convenience-seeking” group exhibiting lower healthy eating competency (MN(nutrition-conscious group) = 3.68, MP(passive-food-consumer group) = 3.40, MC(convenience-seeking group) = 3.52, P < 0.001), safe eating competency (MN = 3.87, MP = 3.57, MC = 3.77, P < 0.001), and satisfaction (MN = 3.36, MP = 3.23, MC = 3.25, P = 0.04) than the “nutrition-conscious” group.
Conclusion
This study underscores the need for targeted nutrition programs to address the unique needs of single-person households depending on their characteristics. Specifically, this study highlights the importance of targeted interventions for “convenience-seeking” and “passive food consumer” to promote dietary competency and encourage healthy dietary behavior.

Effects of a multi-component program based on partially hydrolyzed guar gum (Sunfiber^®) on glycemic control in South Korea: a single-arm, pre-post comparison pilot clinical trial: Hyoung Su Park, A-Hyun Jeong, Hyejung Hong, Hana Jang, Hye-Jin Kim; Korean J Community Nutr 2025;30(1):40-52. Published online February 28, 2025; DOI: https://doi.org/10.5720/kjcn.2024.00276; Correction in: Korean J Community Nutr 2025;30(2):173

Abstract PDF PubReader ePub: Objectives
The aim of this study was to assess the impact of a multi-component program, including partially hydrolyzed guar gum (PHGG, Sunfiber®) supplementation, on glycemic control, gut health, and nutritional status to support diabetes prevention and management among Korean adults.
Methods
A single-arm trial was conducted with 29 adults (aged 20-55 years) with fasting plasma glucose (FPG) ≥ 100 mg/dL. Over a six-week period, participants engaged in a multi-component program that incorporated the supplementation of PHGG (Sunfiber®, 12.5 g/day), weekly nutritional coaching, and the use of continuous glucose monitoring devices. The program’s effectiveness was evaluated by measuring FPG and glycated hemoglobin (HbA1c) levels through blood tests conducted before and after the intervention. Improvements in gut health were gauged using the Korean Gut Quotient Measurement Scales, while enhancements in nutritional status were assessed using the Nutrition Quotient (NQ) and surveys that evaluated improvements in gut health and nutritional status.
Results
Participants’ average age was 43.89 years, with approximately 80% being male. Most participants (about 75%) were classified as overweight or obese. After six-weeks, 17 participants who adhered closely to the program (meeting certification criteria) exhibited significant reductions in key blood glucose markers. FPG levels decreased from 113.06 ± 23.16 mg/dL to 106.24 ± 16.33 mg/dL (P < 0.05), and HbA1c levels decreased from 6.08% ± 0.81% to 5.87% ± 0.53% (P < 0.05). The NQ evaluation revealed significant increases in comprehensive nutrition scores, and in the balance and practice domain scores for all participants (P < 0.05). Furthermore, in the gut health survey, approximately 82.1% of all participants reported experiencing positive changes.
Conclusion
Among adults with elevated FPG levels, a multi-component intervention program that included PHGG (Sunfiber®) supplementation, structured dietary management, and the use of health-monitoring devices showed significant benefits in improving glycemic control, overall nutritional status, and gut health.

Biochemical characteristics, nutrient intakes, and chronic disease risk according to the dietary fat energy ratio in middle-aged Korean: a cross-sectional study using data from the 7th (2016–2018) Korean National Health and Nutrition Examination Survey: Ga-Hyeon Jeong, Sook-Bae Kim; Korean J Community Nutr 2024;29(6):528-540. Published online December 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00304

Abstract PDF PubReader ePub

Objectives
This study aimed to examine health-related characteristics and chronic disease risk in middle-aged Koreans based on their fat energy intake ratio.
Methods
We analyzed data from 7,274 Koreans aged 40–64 years using the 7th (2016–2018) Koreans National Health and Nutrition Examination Survey. Participants were classified into three groups based on their fat energy intake ratio: insufficient (< 15%), adequate (15%–30%), and excessive (> 30%). We assessed their socio-demographic characteristics; lifestyle characteristics; biochemical characteristics; quantitative and qualitative nutrient intakes, measured using dietary reference intakes for Koreans and index of nutrition quality (INQ); and chronic disease risk.
Results
Significant differences were observed between the groups in age, gender, income, education, and residence region. The insufficient group had the highest proportion of older adults, male, lower income, rural residents, and lower education levels. The groups differed significantly in lifestyle characteristics, with the insufficient group having the highest rates of no walking, heavy drinking, smoking, and poor subjective health perception. Biochemical characteristics in the insufficient group exhibited the lowest levels for fasting blood glucose, hemoglobin A1c, and triglycerides. Significant differences were found in both the quantitative and qualitative intake of nutrients. The insufficient group had the lowest intake of most nutrients except fiber, whereas the excessive group had the lowest fiber intake. Based on the INQ, vitamin A and Ca were the lowest in the insufficient group, and vitamin C and folic acid were the lowest in the excessive group. The risk of diabetes mellitus and metabolic syndrome was highest in the deficient group, and the risk of liver cirrhosis was highest in the excessive group.
Conclusion
Insufficient or excessive fat energy intake ratio negatively affects nutrient intake and chronic disease risk. Fat energy intake of 15%–30% is important for improving nutrient intake and managing chronic diseases, such as diabetes mellitus, metabolic syndrome, and liver cirrhosis. We suggest that education and an appropriate social environment are necessary to ensure this fat energy intake.

Co-occurrence network and pattern of school lunch using big data and text-mining using data from the 2021–2023 school meal menu information on the NEIS open educational information portal: an exploratory study: Hyeyun Kang, Jimi Kim; Korean J Community Nutr 2024;29(6):514-527. Published online December 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00297

Abstract PDF Supplementary Material PubReader ePub: Objectives
This study aimed to use big data from elementary, middle, and high school lunches to determine the primary food groups and menu items that contribute to lunch meals through text-mining and investigate the variations in food groups and menu composition patterns across different grade levels.
Methods
Between 2021 and 2023, a total of 7,892,456 lunch menus from 17 cities and provinces in South Korea were analyzed using big data from the National Education Information System (NEIS) system. After undergoing text preprocessing for text-mining, the collected menus were classified into 34 food groups based on primary ingredients and cooking methods, excluding the types of rice and kimchi. Subsequently, analyses of term frequency, term frequency-inverse document frequency (TF-IDF), centrality, and co-occurrence networks were performed on the food group and menu data.
Results
According to the TF-IDF, the most frequent food group across all grade levels was soup and seasoned vegetables, whereas milk was the most frequently provided menu. As the grade level increased, the frequency of grilled and fried food increased. In elementary schools, fruits exhibited the highest centrality, whereas soup had the highest centrality in middle and high schools. Co-occurrence frequency revealed that the soup-fruit combination was the most common in elementary schools, whereas soup and seasoned vegetables were most frequently paired in middle and high schools. The co-occurrence network of food groups and menus further indicated that menus regularly provided as standard meals and those frequently offered as special meals formed distinct communities.
Conclusion
This study investigated the food groups and menu provision patterns in school meals through text-mining techniques applied to large-scale school lunch. The findings may contribute in enhancing the quality of nutritional management, school foodservice, and menu composition of school meal programs.

Impact of a public health center nutrition education program on patients with type 2 diabetes in a primary care-based chronic disease management project: a pilot intervention study: Haerim Yang, Yoo Kyoung Park, Ji-hyun Lee, Hee-Sook Lim, Heejoon Baek, Hyejin Lee, Haeran Park, Pyunghwa Lee, Jooyoun Chung, Won Gyoung Kim; Korean J Community Nutr 2024;29(6):492-503. Published online December 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00018

Abstract PDF PubReader ePub: Objectives
We investigated the impact of an advanced “Nutrition Education Program” on patients with Diabetes mellitus, type 2 from public health centers enrolled in a primary health care-based chronic disease management project. This 12-week dietary management program was developed by the Korea Health Promotion and Development Institute. We assessed if this program improved glycemic control and other health indicators through dietary and nutritional improvements.
Methods
Seventeen patients with Diabetes mellitus type 2 were enrolled in the “Nutrition Education Program.” These patients were referred to public health centers for lifestyle management based on physician assessments at local clinics that were participating in a pilot project on primary health care-based chronic disease management. The participants attended the program comprising face-to-face basic, in-depth, and practical training sessions at the health center during the third, fifth, and seventh weeks, respectively. Anthropometric measurements, body composition analysis, blood biochemical characteristics, nutritional knowledge, and self-efficacy evaluation were performed before and after the program. Data were analyzed using SPSS ver. 28.0.
Results
The mean age of the participants was 62 years, and most participants were female (14, 82.4%). No significant changes in patients’ anthropometric measurements or body composition were observed after the training. However, significant reductions were observed in the blood biochemical characteristics, including glycated hemoglobin, total cholesterol, and low-density lipoprotein levels. Additionally, patients’ nutritional knowledge and self-efficacy scores increased significantly.
Conclusions
The “Nutrition Education Program” helped in improving glycemic control and other health indicators in patients with Diabetes mellitus type 2. Further research is required to objectively confirm the long-term and sustained effects of the program in a controlled study.

Effects of a nutrition education program on metabolic syndrome risk factors in middle-aged Korean adults: an intervention study: Minji Kang, Young-Hee Park, Subeen Kim, Eunyoung Tak, Hyun Wook Baik, Hee Young Paik, Hyojee Joung; Korean J Community Nutr 2024;29(4):265-277. Published online August 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00005

Abstract PDF PubReader ePub: Objectives
This study was conducted to evaluate the effects of a nutrition education program on metabolic syndrome in middle-aged Korean adults.
Methods
A total of 411 Korean adults 30–59 years of age were allocated randomly into three groups: the nutrition education group for promoting Han-sik consumption (HG), the nutrition education group for eating balanced diet (EG), and the control group (CG). The HG and EG received four face-to-face nutrition education sessions over 16 weeks to improve nutritional problems based on the individual’ usual diet. Effectiveness of the program was evaluated with the differences of self-reported dietary behaviors, dietary intakes, anthropometric measurements and biochemical indices between the baseline and the end of the nutrition education program. The changes within groups were analyzed using paired t-test and McNemar test and effectiveness among three groups was analyzed by repeated analysis of variance.
Results
After the nutrition education, the percentages of participants who achieved the recommended food group consumption in the Korean Food Guidance Systems significantly increased in HG (P = 0.022). Body weight (P = 0.007), body mass index (P = 0.002), and triglycerides (P = 0.002) significantly decreased in HG. Waist circumference and diastolic blood pressure decreased in all three groups (P < 0.05).
Conclusions
This study found that tailored nutrition education program for middle aged Korean adults showed beneficial effects on improving dietary behaviors and metabolic syndrome risk factors. Further studies are needed to assess the long-term effects of the nutrition education programs on metabolic syndrome risks.

Intake of energy and macronutrients according to household income among elementary, middle, and high school students before and during the COVID-19 pandemic: a cross-sectional study: Chae-Eun Jeong, Heejin Lee, Jung Eun Lee; Korean J Community Nutr 2024;29(3):234-252. Published online June 30, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.3.234

Abstract PDF PubReader ePub

Objectives
This study examined the intake of energy and macronutrients among elementary, middle, and high school students according to household income before the COVID-19 pandemic (2016–2019), during the social distancing period (2020–2021), and after the social distancing measures were lifted (2022).
Methods
We included 5,217 students aged 5–18 from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2016 and 2022. Dietary intake was assessed using one-day 24-hour dietary recalls. We estimated the least squares means (LS-means) of intake according to household income for each period using a weighted linear regression model, adjusted for age and sex. Differences in LS-means between the periods were analyzed using the t-test.
Results
During the social distancing period, the LS-means of energy intake among students decreased significantly by 143.2 kcal/day compared to pre-pandemic levels (P < 0.001). Students from low-income households experienced a more pronounced decrease in energy intake (−379.1 kcal/day, P < 0.001) and macronutrient intake compared to those from other income groups. Energy intake at school significantly declined for all income groups during the social distancing period compared to before the pandemic. No significant changes in home energy intake were observed among low-income students, whereas there was an increase for students from higher-income groups. Before the pandemic, 8.5% of students from low-income households reported insufficient food due to economic difficulties; this figure rose to 21.3% during the pandemic.
Conclusions
During the pandemic, students from low-income families experienced significantly lower intake of energy and macronutrients compared to pre-pandemic levels. The most substantial reductions were noted among low-income students, largely due to the lack of compensation for decreased school-based intake with increased intake at home.

Objectives
Metabolic disease is strongly associated with future insulin resistance, and its prevalence is increasing worldwide. Thus, identifying early biomarkers of metabolic-related disease based on serum profiling is useful to control future metabolic disease. Our study aimed to assess the association of serum branched chain amino acids (BCAAs) and aromatic amino acids (AAAs) ratio and metabolic disease according to body mass index (BMI) status among Korean adults.
Methods
This cross-sectional study included 78 adults aged 20–59 years in Korea. We compared serum amino acid (AA) levels between adults with normal-weight and adults with obesity and investigated biomarkers of metabolic disease. We examined serum AA levels, blood profile, and body composition. We also evaluated the association between serum AAs and metabolic-related disease.
Results
The height, weight, BMI, waist circumference, hip circumference, waist-hip-ratio, body fat mass, body fat percent, skeletal muscle mass, systolic blood pressure, and diastolic blood pressure were higher in the group with obesity compared to normal weight group. The group with obesity showed significantly higher levels of BCAA, AAA, and BCAA and AAA ratio. Further, BCAA and AAA ratio were significantly positively correlated with triglyceride, body weight, and skeletal muscle mass. The evaluation of metabolic disease risks revealed an association between the ratios of BCAAs and AAAs, hypertension, and metabolic syndrome.
Conclusions
Our study is showed the associations between BCAA and AAA ratio, obesity, and obesity-related diseases using various analytical approaches. The elevated BCAA and AAA ratio could be early biomarkers for predicting future metabolic diseases in Korean population.

Association between dietary intake, body measurements, and urinary bone resorption markers in young adults with osteopenia and osteoporosis: a cross-sectional study: Mi-Hyun Kim, Mi-Kyeong Choi; Korean J Community Nutr 2023;28(4):282-292. Published online August 31, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.4.282

Abstract PDF: Objectives
Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults.
Methods
A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group.
Results
Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P< 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex.
Conclusions
In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.

Mercury exposure is associated with obesity: a systematic review and meta-analysis: Jimin Jeon, Kyong Park; Korean J Community Nutr 2023;28(3):192-205. Published online June 30, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.3.192

Abstract PDF

Objectives
Previous studies have evaluated the association between mercury exposure and obesity but have yielded mixed conclusions. The aim of this study was to systematically review and summarize scientific evidence regarding the association between mercury exposure and obesity in the human population.
Methods
We conducted a systematic search of PubMed, Web of Science, Scopus, and Science Direct for articles related to mercury exposure and obesity. Meta-analyses of the highest and lowest categories of mercury levels were evaluated using a random effects model. Begg’s test was used to detect publication bias.
Results
A total of 9 articles were included. The pooled random effects odds ratio (OR) for mercury exposure and obesity of all 9 studies was 1.66 (95% confidence interval [CI]: 1.16-2.38). This positive association was evident in adults (OR: 1.61, 95% CI: 1.02-2.54) and among studies with Asian populations (OR: 2.00, 95% CI: 1.53-2.59), but not among those with North America/African populations (OR: 0.90, 95% CI: 0.50-1.65).
Conclusions
The present meta-analysis identified a positive association between mercury exposure and obesity. These findings suggest that toxic environmental metals such as mercury may be an important risk factor for obesity along with dietary habits and lifestyles.

Micronutrients and prevention of cervical pre-cancer in HPV vaccinated women: a cross-sectional study: Chandrika J Piyathilake, Suguna Badiga, Nongnut Thao, Pauline E Jolly; Korean J Community Nutr 2023;28(1):61-73. Published online February 28, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.1.61

Abstract PDF

Objectives
Prophylactic vaccines against high-risk human papillomaviruses (HR-HPVs) hold promise to prevent the development of higher grade cervical intraepithelial neoplasia (CIN 2+) and cervical cancer (CC) that develop due to HR-HPV genotypes that are included in HPV vaccines, but women will continue to develop CIN 2+ and CC due to HR-HPV genotypes that are not included in the quadrivalent HPV vaccine (qHPV) and 9-valent HPV vaccine (9VHPV). Thus, the current vaccines are likely to decrease but not entirely prevent the development of CIN 2+ or CC. The purpose of the study was to determine the prevalence and determinants of CIN 2+ that develop due to HR-HPVs not included in vaccines.
Methods
Study population consisted of 1476 women tested for 37 HPVs and known to be negative for qHPVs (6/11/16/18, group A, n = 811) or 9VHPVs (6/11/16/18/31/33/45/52/58, group B, n = 331), but positive for other HR-HPVs. Regression models were used to determine the association between plasma concentrations of micronutrients, socio-demographic, lifestyle factors and risk of CIN 2+ due to HR-HPVs that are not included in vaccines.
Results
The prevalence of infections with HPV 31, 33, 35 and 58 that contributed to CIN 2+ differed by race. In group A, African American (AA) women and current smokers were more likely to have CIN 2 (OR = 1.76, P = 0.032 and 1.79, P = 0.016, respectively) while in both groups of A and B, those with higher vitamin B12 were less likely to have similar lesions (OR = 0.62, P = 0.036 and 0.45, P = 0.035, respectively).
Conclusions
We identified vitamin B12 status and smoking as independent modifiable factors and ethnicity as a factor that needs attention to reduce the risk of developing CIN 2+ in the post vaccination era. Continuation of tailored screening programs combined with non-vaccine-based approaches are needed to manage the residual risk of developing HPVrelated CIN 2+ and CC in vaccinated women.

Comparison of the Nutrient Intake and Health Status of Elderly Koreans According to their BMI Status: Focus on the Underweight Elderly Population: You-Sin Lee, Yoonna Lee; Korean J Community Nutr 2022;27(5):422-434. Published online October 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.5.422

Abstract PDF

Objectives
With an increase in the population of the elderly in Korea, their nutritional status has become a cause for concern. This study was designed to compare the nutritional intake and health status of the Korean elderly according to their body mass index.
Methods
The subjects were 3,274 elderly people aged 65 and above who had participated in the 2016-2018 Korea National Health and Nutrition Examination Survey. The subjects were divided into four groups: underweight, normal, overweight, and obese, based on their BMI. The general characteristics, daily energy, and nutrient intakes, nutrient intakes compared to the recommended nutrient intake, percentage of participants whose nutrient intake was lower than the estimated average requirement (EAR), index of nutrient quality, the mean adequacy ratio (MAR), intakes by food group, and health status of the four groups were compared.
Results
Underweight elderly people showed lower energy, lipids, dietary fiber, vitamin C, riboflavin, niacin, phosphorus, sodium, and potassium intake and MAR score (P < 0.001) compared to the normal or obese elderly. The mean protein, riboflavin, niacin, vitamin C, phosphorus, and iron intake of the underweight elderly was lower than the EAR (P < 0.05). Underweight elderly people also had a lower intake of vegetables and fats, oil and sweets food groups than the other groups (P < 0.001). The prevalence of diabetes and dyslipidemia was higher in the obese group, but the percentage of anemia was higher in the underweight group.
Conclusions
Underweight elderly people were vulnerable to undernutrition and were at a higher risk of anemia.

Investigation of Millennials' Perception of Vegan Trends and Future Needs: Eun-Hye Song, Bok-Mi Jung; Korean J Community Nutr 2022;27(5):373-386. Published online October 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.5.373

Abstract PDF

Objectives
This study examined the perception of the vegan trend of millennials and their future needs.
Methods
This study was conducted online from June 21, 2021, to July 15, 2021, targeting 425 adult men and women born between 1980 and 2000. The contents of the survey were divided into four categories: general information, awareness of vegetables, awareness of vegan trends, and future needs for vegan trends.
Results
Most respondents recognized the importance of eating vegetables and perceived vegetarianism and veganism as a lifestyle. Regarding the perception of the vegan trend, the highest response rate was ‘The vegan trend is to be satisfied with my life regardless of other people’, while the lowest response rate was ‘The vegan trend is only a temporary fad’. The reasons for purchasing vegan products with high response rates were ‘interest in the earth and environment’, ‘protection of animal rights’, and ‘thinking about health’. The type of vegan product wanted in the future was delicious food, and convenience level was in the order of ‘completely cooked’, ‘half-cooked’, and ‘pre-processed’. Among the sustainable vegetarian types that millennials responded, ‘semi-vegetarian’, which can consume most animal products excluding red meat, showed the highest response rate.
Conclusions
The positive perceptions about vegetables are expected to increase. Efforts should be made to develop convenient meals using vegetables and provide reasonable prices to expand vegetable intake.

Dietary Behaviors Associated with Health Perception of Korean Adolescents from Multicultural Families: based on data from the 2017 ~ 2019 Korea Youth Risk Behavior Surveys: YueRong Hu, SuJin Song; Korean J Community Nutr 2022;27(3):192-204. Published online June 30, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.3.192

Abstract PDF

Objectives
This study examined the association between dietary behaviors and perceived health status among Korean adolescents from multicultural families.
Methods
This cross-sectional study included 2,459 Korean adolescents from multicultural families (aged 13 ~ 18 years) who participated in the 2017 ~ 2019 Korea Youth Risk Behavior Surveys. Information on the sociodemographic variables, dietary behaviors, and lifestyle variables was selfreported using a web-based questionnaire. The dietary behaviors analyzed in this study were the breakfast and food intake frequencies, including fruit, vegetable, milk, fast food, carbonated drink, sweet drink, and high caffeine/energy drinks. The adolescents’ health perception was self-rated as healthy, average, or unhealthy. The dietary behaviors associated with health perception were examined using a multiple logistic regression after adjusting for the confounding variables.
Results
In this study population, 7.6% of adolescents perceived their health status as unhealthy, and 25.4% perceived it as average. The adolescents who were girls, middle school students, and in households with a low economic status showed significantly higher percentages of poor health perception (P-values < 0.001). Skipping breakfast was significantly associated with a negative health perception. Compared to the adolescents who consumed fruits every day, those who did not consume fruits during the previous week showed a higher odd ratio (OR) for a negative health perception [OR = 2.29, 95% confidence interval (CI) = 1.32–3.97]. The adolescents who frequently consumed carbonated drinks ( 5 times/week) perceived their health status as unhealthy relative to those who did not consume carbonated drinks (OR = 2.15, 95% CI = 1.25–3.71). Skipping breakfast was significantly associated with an increased OR for a negative health perception in girls but not in boys. Compared to adolescents with a normal weight, those with overweight/ obesity (OR = 1.75, 95% CI = 1.21–2.52) and underweight (OR = 2.19, 95% CI = 1.25–3.82) showed higher ORs for negative health perception. Positive associations of overweight/obesity and underweight with negative health perception were observed in boys but not in girls.
Conclusions
Dietary behaviors and weight status were associated with the health perception in Korean adolescents from multicultural families. These findings suggest that nutrition interventions on breakfast intake and healthy food choices for this population might effectively improve their weight and perceived health status.

A Study on the Dietary and Lifestyle Changes of Middle-Aged Women in the Gwangju Area in the COVID-19 Era: Moon-Soon Kim, Bok-Mi Jung; Korean J Community Nutr 2021;26(4):259-269. Published online August 31, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.4.259

Abstract PDF

Objectives
This study aimed to investigate the changes in the eating habits and lifestyle of middle-aged women in Gwangju during the COVID-19 pandemic. Methods: A total of 428 middle-aged women aged between 40 and 60 participated in a survey relating to general information, food and lifestyle, health functional food, and menopausal symptoms. The correlation between the variables was analyzed. Results: In the positive habits, the intake of nutritional supplements for immunity enhancement increased the most, followed by the use of media to learn healthy eating tips, and diets including healthy food. Negative habits increased in the order of frequency of taking delivery orders, levels of stress or anxiety, and time spent sitting or watching movies. In the case of recommended foods, the intake increased the most in the order of eggs, fruits, vegetables, milk/dairy products, and seaweed. Non-recommended foods increased in the order of meat, bread, rice, and noodles. The awareness of health functional foods was in the increasing order of interest, knowledge, consumption experience, and purchase amount. The type of health functional food intake was in the increasing order of probiotics, multivitamin and mineral supplements, vitamin C, collagen, and omega-3. Menopausal symptoms were in the increasing order of bone and joint pain, poor sleep quality, emotional ups and downs, loneliness, and feeling of emptiness. In the correlation of major variables, positive habits showed a significant positive correlation with recommended food intake and the recognition of health functional foods. Negative habits showed a significant positive correlation with non-recommended food intake and a significant positive correlation with menopausal symptoms. Recommended food intake showed a significant positive correlation with health functional food recognition and intake and menopausal symptoms. Conclusions: This study suggests that it is necessary to establish social measures to reduce the negative effects of the COVID-19 pandemic on middle-aged women and to ensure effective self-management through a healthy lifestyle since the pandemic has a long-term impact.

Vegetable and Nut Food Groups are Inversely Associated with Hearing Loss- a Cross-sectional Study from the Korea National Health and Nutrition Examination Survey: Sunghee Lee, Jae Yeon Lee; Korean J Community Nutr 2020;25(6):512-519. Published online December 31, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.6.512

Abstract PDF: Objectives
A cross-sectional study was conducted to investigate the associations between food groups and hearing loss. Methods: Data of 1,312 individuals were used from the Korea National Health and Nutrition Examination Survey 2013. Hearing loss was determined with a pure tone average (PTA) of greater than 25 dB in either ear. The PTA was measured as the average hearing threshold at speech frequencies of 0.5, 1, 2, and 4 kHz. The dietary intake was examined with a food frequency questionnaire with 112 food items. The food items were classified into 25 food groups. A weighted logistic regression was used to investigate the association. Results: Individuals in the highest tertile of vegetables and nuts food groups were less likely to have hearing loss than those in the lowest tertile [Odds Ratio (OR) = 0.58 (95% Confidence interval (CI) 0.38-0.91), P = 0.019; OR = 0.59 (95% CI 0.39-0.90), P = 0.020, respectively], after adjusting for confounding variables of age, sex, body mass index, drinking, smoking, diabetes, hypertension, and physical activity. Conclusions: In this cross-sectional study, we observed that high intake of vegetables and nuts food groups revealed significant inverse associations with hearing loss, after adjusting for confounding variables among 1,312 participants.

Biochemical Characteristics and Dietary Intake according to the Frequency of Milk Consumption in Korean Adolescents: Data from the 2010~2011 Korea National Health and Nutrition Examination Survey: Ji Hyun Kim, Sook-Bae Kim; Korean J Community Nutr 2020;25(6):485-501. Published online December 31, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.6.485

Abstract PDF

Objectives
The purpose of this study was to examine the biochemical characteristics and dietary intake of adolescents aged 12 to 18 years according to the frequency of milk consumption. Methods: Data from the 2010~2011 Korea National Health and Nutrition Examination Survey was used for the study. The study examined adolescents’ (12~18 years) demographic characteristics (house income level, residence region, skipping or not-skipping of breakfast/lunch/dinner, eatingout frequency), anthropometric characteristics (height, weight, weight status), biochemical characteristics (fasting plasma glucose, blood urea nitrogen, creatine, triglycerides, cholesterol, HDL-cholesterol, hemoglobin, hematocrit) and nutrient intakes through quantitative and qualitative evaluation using the Korean Dietary Reference Intakes (KDRI), index of nutrition quality (INQ), nutrition adequacy ratio (NAR) of 3 groups (< 1/week, 1~6/week, 1/day) according to the frequency of milk consumption. Results: There were significant differences in gender and income levels among the 3 groups. There were no differences in height, weight, and weight status among groups. There were differences in biochemical characteristics and nutrient intake. In boys, there were differences in the mean of BUN and HDL-cholesterol, in quantitative intakes of riboflavin, calcium, phosphorus, potassium by KDRI levels, in qualitative intakes of riboflavin, calcium, phosphorus by INQ and riboflavin, calcium, phosphorus by NAR among 3 groups. In girls, there were differences in the mean of blood urea nitrogen, creatine, HDL-cholesterol, in quantitative intakes of protein, riboflavin, calcium, phosphorus by KDRI levels, in qualitative intakes of riboflavin, calcium, phosphorus by INQ and riboflavin, calcium, phosphorus by NAR among the 3 groups. Conclusions: In Korean adolescents, boys had a higher frequency of milk consumption than girls, and higher the income level, higher the frequency of milk consumption. Consumption of milk appeared to have a positive association with triglycerides, HDL-cholesterol, and indices related to muscle mass. Regular consumption of milk is an important factor in enhancing the intake of riboflavin, calcium, and phosphorus, which adolescents lack. The results of the study indicate a need to prepare an environment and education program to increase milk consumption in adolescents at home and school.

Evaluation of Nutritional Status of Vitamins and Minerals According to Consumption of Dietary Supplements in Korean Adults and the Elderly: Report Based on 2017 Korea National Health and Nutrition Examination Survey data: Ji-Myung Kim; Korean J Community Nutr 2020;25(4):329-339. Published online August 31, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.4.329

Abstract PDF

Objective
This study was undertaken to evaluate the intake of vitamins and minerals from dietary supplements (DSs) in Korean adults and elderly.
Methods
Data for this study was generated from the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). We analyzed 4,204 individuals aged 19 years and older (2,579 users and 1,625 non-users). The survey included 24-h recall questions on food and DS intakes, as well as questions on DS use over the past year. The nutrient DSs evaluated were calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C. Total nutrient intakes were obtained by combining nutrient intakes of foods and DSs consumed by each subject.
Results
Most micronutrient intakes from food (except for thiamin) in adult users, and the four micronutrient intakes (iron, vitamin A, vitamin B₂ and vitamin C) in elderly users, were significantly higher than values obtained in non-users. For total intake of nutrients and DSs, both adult and elderly users had a significantly higher intake than non-users. While proportions below Estimated Average Requirements for all micronutrients by adding respective DSs in users were significantly reduced in adults and elderly as compared to non-users, the proportions of above Tolerable Upper Intake Levels for calcium and vitamin A in adults, and vitamin A in elderly, were significantly increased. In the total subjects examined, consumption of DSs was associated with lower odds ratios of undernutrition of micronutrients, and with higher odds ratios of overnutrition of calcium, iron, and vitamin A, as compared to non-users of DSs.
Conclusions
Although DSs consumption by adults and the elderly improves the micronutrient status, it also increases the risk of excessive intake of certain vitamins and minerals.

Effect of Nutrition Counseling by Nutrition Care Process on Diet Therapy Practice and Glycemic Control in Type 2 Diabetic Patients: Tae-Jeong Bae, Na-Eun Jeon, Soo-Kyong Choi, Jung-Sook Seo; Korean J Community Nutr 2020;25(3):214-225. Published online June 30, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.3.214

Abstract PDF

Objectives
This study examined the effects of nutrition counseling by the nutrition care process (NCP) on diet therapy practice and glycemic control in patients with type 2 diabetes mellitus.
Methods
The survey was conducted on 49 patients whose hemoglobin A1c (HbA1c) level ranged from 6.5% to below 10% among patients aged 30∼60s with type 2 diabetes mellitus. Nutrition counseling by the NCP process was carried out twice: first nutrition counseling and follow up counseling. The questionnaires were composed of 54 questions in five fields (general characteristics, health-related behaviors, diet therapyrelated items, dietary life, diet therapy-related knowledge, diet therapy-related barriers). Nutrition intervention in nutrition counseling was performed based on the individualized diagnosis of NCP.
Results
All the subjects practiced self-monitoring of their blood glucose levels, regular exercise, and diet therapy after NCP-based nutrition counseling. Diet therapy-related knowledge and practice by the subjects were improved after nutrition counseling. While the intake of boiled white rice decreased, the intake of boiled brown rice and barley rice in the subjects increased significantly. After nutrition counseling, the weight and HbA1c of the subjects decreased.
Conclusions
These results suggest that personalized nutrition counseling by NCP process is effective for diet therapy compliance and glycemic control of type 2 diabetic patients.

Comparison of 24-hour Recalls with a Food Frequency Questionnaire in Assessing Coffee Consumption: The Health Examinees (HEXA) Study: An Na Kim, Jiyoung Youn, Hyun Jeong Cho, Taiyue Jin, Sangah Shin, Jung Eun Lee; Korean J Community Nutr 2020;25(1):48-60. Published online February 29, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.1.48

Abstract PDF PubReader ePub

OBJECTIVES
Most cohort studies used food frequency questionnaires (FFQ) to evaluate coffee consumption as it assesses habitual dietary patterns, whereas some studies have used the 24-hour recalls (24HR) as it elicits in-depth description of foods and the amount eaten. The aim of this study was to compare FFQs and 24HR to assess the consumption of various types of coffee.
METHODS
We included 25,904 participants aged 40 years or older from the Health Examinees (HEXA) Study of the Korean Genome and Epidemiologic Study (KoGES). Each participant completed one FFQ and one-day (n=11,280) or two-day 24HR (n=14,624). We classified coffee types into: black coffee, coffee with sugar and cream, and coffee with sugar alone or cream alone. We compared the proportions of nondrinkers, black coffee, and coffee with sugar and cream through FFQ and 24HR.
RESULTS
Among those who completed one FFQ and one-day 24HR, 39.4% of â€œnondrinkersâ€ on one-day 24HR reported that they did not drink coffee on their FFQs. Whereas among those who complete two-day 24HR, 71.2% of â€œnondrinkersâ€ on two-day 24HR said that they did not drink coffee on their FFQs. Among those who completed one FFQ and oneday 24HR, 58.3% marked â€œblack coffeeâ€ on one-day 24HR said that they drank black coffee on their FFQs. Among those who complete two-day 24HR, 58.8% marked â€œblack coffeeâ€ on two-day 24HR said that they drank black coffee on their FFQs. The kappa coefficients and percent agreements were 0.4 and 59.6%, respectively, for the comparison of coffee intake between FFQ and one-day 24HR, and 0.6 and 72.8%, respectively, for the comparison of coffee intake between FFQ and two-day 24HR.
CONCLUSIONS
We found discrepancies between FFQs and 24HR in the types of coffee consumed. Such limitations should be considered when using the 24HR data to examine the effect of coffee consumption on disease development.

Effects of Low-carbohydrate and High-fat Diet Supplemented with Ketogenic Drink on Cognitive Function and Physical Performance in the Elderly at High Risk for Dementia: Eun Ji Kim, Jung Sik Park, Won Sun Choi, Yoo Kyoung Park; Korean J Community Nutr 2019;24(6):525-534. Published online December 31, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.6.525

Abstract PDF PubReader

OBJECTIVES
Reduced glucose utilization in the main parts of the brain involved in memory is a major cause of Alzheimer's disease, in which ketone bodies are used as the only and effective alternative energy source of glucose. This study examined the effects of a low-carbohydrate and high-fat (LCHF) diet supplemented with a ketogenic nutrition drink on cognitive function and physical activity in the elderly at high risk for dementia.
METHODS
The participants of this study were 28 healthy elderly aged 60-91 years showing a high risk factor of dementia or whose Korean Mini-Mental State Examination (K-MMSE) score was less than 24 points. Over 3 weeks, the case group was given an LCHF diet with nutrition drinks consisting of a ketone/non-ketone ratio of 1.73:1, whereas the control group consumed well-balanced nutrition drinks while maintaining a normal diet. After 3 weeks, K-MMSE, body composition, urine ketone bodies, and physical ability were all evaluated.
RESULTS
Urine ketone bodies of all case group subjects were positive, and K-MMSE score was significantly elevated in the case group only (p=0.021). Weight and BMI were elevated in the control group only (p<0.05). Grip strength was elevated in all subjects (p<0.01), and measurements of gait speed and one leg balance were improved only in the case group (p<0.05).
CONCLUSIONS
We suggest that adherence to the LCHF diet supplemented with a ketogenic drink could possibly influence cognitive and physical function in the elderly with a high risk factor for dementia. Further, we confirmed the applicability of this dietary intervention in the elderly based on its lack of any side effects or changes in nutritional status.

Home Meal Replacement Use and Eating Habits of Adults in One-Person Households: Mi Kyeong Choi, Eun Sun Park, Mi Hyun Kim; Korean J Community Nutr 2019;24(6):476-484. Published online December 31, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.6.476

Abstract PDF PubReader

OBJECTIVES
The rise of one-person households may have consequences for food consumption patterns, and eating habits. This study investigated the home meal replacement (HMR) use and eating habits among adults in their 20s-30s living in one-person households.
METHODS
A total of 247 adults aged 26â€“39 years participated in this study. The subjects were divided into three group according to the household type; one-person households (n=80), two-person households (n=49), and multi-family (three and more members) households (n=118). Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and their eating habits were all compared.
RESULTS
The mean age of the subjects was 30.5 years, 47.8% were male, and there was no significant difference in age, gender, occupation, and monthly income according to the type of household. The intake frequency of total HMR and ready-to-eat foods was significantly higher in one-person households among the three groups. People in one-person households consumed more HMRs alone, and spent more money to buy HMRs. Undesirable dietary habit scores like unbalanced eating (p<0.05) and eating salty foods (p<0.05) were significantly higher in the one-person households. Among the total subjects, the unbalanced eating scores showed a significant positive correlation with the intake frequency of ready-toeat foods, while the unbalanced eating scores showed negative correlation with the preference of fresh convenience foods. The scores for eating salty foods showed a significant positive correlation with the intake frequency and preference of ready-to-eat foods and ready-to-cook foods, while there was negative correlation with the intake frequency and preference of fresh convenience foods.
CONCLUSIONS
Adults in their 20sâ€“30s in one-person households consumed more ready-to-eat foods than those in multi-family households. In addition, people with one-person households had more unbalanced diets and ate more salty foods, and these undesirable eating habits showed a significant positive correlation with the use of ready-to-eat or ready-to-cook foods. These results should be addressed for producing healthier ready-to-eat/ready-to-cook foods and implementing nutrition education for making healthy food choices of one-person households, which are steadily increasing.

OBJECTIVES
This study investigated dietary and lifestyle factors associated with the weight status among Korean adolescents in multicultural families.
METHODS
This cross-sectional study analyzed 1,751 multicultural families' adolescents who participated in the 2017â€“2018 Korea Youth Risk Behavior Surveys. Information on dietary and lifestyle factors was self-reported using a web-based questionnaire and this information included breakfast and foods consumption, perceived health status, alcohol drinking, smoking, physical activity, and weight control efforts. Body mass index (BMI) was calculated based on the self-reported height and body weight (kg/mÂ²). Weight status was assessed according to the 2017 Korean National Growth Chart: underweight (weight-for-age <5(th) percentiles), overweight (85(th)â‰¤ BMI-for-age <95(th) percentiles), and obese (BMI-for-age â‰¥95(th) percentiles). Multiple logistic regression analysis was performed to examine the dietary and lifestyle factors associated with weight status after adjustment for covariates.
RESULTS
Among Korean adolescents from multicultural families, the prevalence of overweight/obesity was 20.9%, whereas about 7% of adolescents were underweight. The weight status did not show differences according to gender, school level, area of residence, and household income. Compared to adolescents who did not have breakfast during the previous week, those who had breakfast 3â€“4 days/week and â‰¥5 days/week had a 42% (p=0.021) and a 37% (p=0.009) lower prevalence of overweight/obesity, respectively. The adolescents who frequently consumed carbonated soft drinks (â‰¥5 times/week) showed an odds ratio (OR) of 1.69 (95% CI=1.01â€“2.83) for overweight/obesity relative to those adolescents who did not consume carbonated soft drinks. The OR of being underweight for adolescents who ate fast food â‰¥3 times/week was 1.97 (95% CI=1.04â€“3.71) compared to those adolescents who had not eaten fast food during the previous week.
CONCLUSIONS
Dietary and lifestyle factors were associated with overweight/obesity as well as underweight among Korean adolescents in multicultural families. Our findings could be used to design and provide nutrition interventions for this specific population.

Relationship between Dietary Behaviors and Life Stress of Middle School Students in Gyeonggi Area: Kyung Ae Park, Myoung Sook Lee, Kyung Hee Song; Korean J Community Nutr 2019;24(5):384-394. Published online October 31, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.5.384

Abstract PDF PubReader

OBJECTIVES
The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area.
METHODS
A total of 580 middle school students (295males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress.
RESULTS
For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating.
CONCLUSIONS
This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.

Comparison Analysis of Dietary Behavior and Nutrient Intakes of the Elderly according to Their Family Status: The Korea National Health and Nutrition Examination Survey 2013–2016: Ji Hong Oh, Bok Mi Jung; Korean J Community Nutr 2019;24(4):309-320. Published online August 31, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.4.309

Abstract PDF PubReader

OBJECTIVES
This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender.
RESULTS
Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects.
CONCLUSIONS
The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

Dietary Life, Vitamin D Status and Blood Clinical Indices of University Laboratory Workers: Jung Hyun Hwang, Hong Mie Lee, Jung Hee Kim; Korean J Community Nutr 2019;24(3):245-256. Published online June 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.3.245

Abstract PDF PubReader: OBJECTIVES
Although the number of laboratory workers is constantly increasing every year, few studies have been conducted on the health and nutritional status of these research workers. This study determined the health status of laboratory workers by analyzing their anthropometric indices, dietary life, vitamin D status and blood clinical indices.
METHODS
The subjects consisted of 100 female laboratory workers. This study investigated their diet, anthropometric indices, vitamin D status and blood clinical indices. The subjects were divided into two groups according to their duration of working in a laboratory (<1 year,â‰¥1 year).
RESULTS
The average age and body mass index (BMI) of subjects were 23.18 years and 21.51 kg/m2, respectively Those subjects with over 1 year employment (â‰¥1 year) had a significantly higher waist-hip ratio than that of the subjects with the less than 1 year employment (<1 year). The mean serum vitamin D level of all the subjects was 10.04 ng/mL, which is close to a level of vitamin D deficiency. There was a significantly higher average intake of calories in the over 1 year employment group as compared to that of the less than 1 year employment group. The frequency of eating sweet snacks was significantly higher for the over 1 year employment group. The correlation analysis showed a significant positive correlation between the serum 25-(OH)-vitamin D level and the time of exposure to sunlight, while dietary intake of vitamin D did not show correlation with the serum 25-(OH)-vitamin D level. However, the serum 25-(OH)-vitamin D level was also negatively correlated with both the percentage of body fat and visceral fat.
CONCLUSIONS
Laboratory workers are a very high risk group in terms of their nutritional status of vitamin D. Therefore, they need greater time of exposure to sunlight as well as increasing their dietary consumption of vitamin D. In addition, it is important for laboratory worker to practice regular and balanced dietary habits in order to maintain a healthy life.

Evaluation of the Nutrition Status and Metabolic Syndrome Prevalence of the Members according to the Number of Household Members based on the Korea National Health and Nutrition Examination Survey (2013–2014): Jin Young Lee, Soo Kyong Choi, Jung Sook Seo; Korean J Community Nutr 2019;24(3):232-244. Published online June 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.3.232

Abstract PDF PubReader

OBJECTIVES
This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects.
RESULTS
As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001).
CONCLUSIONS
These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Study on Middle and High School Students' Use of Convenience Foods at Convenience Stores in Incheon: Seul Ki Lee, Mi Kyeong Choi, Mi Hyun Kim; Korean J Community Nutr 2019;24(2):137-151. Published online April 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.2.137

Abstract PDF PubReader

OBJECTIVES
The rapidly changing dietary environment requires a study that addresses the status of middle and high school students regarding their consumption of convenience food sold at convenience stores.
METHODS
This study examined adolescents' lifestyle patterns, dietary habits, and status of consuming convenience food at convenience stores. A total of 659 students (329 middle school students and 330 high school students) in Incheon participated in this questionnaire survey.
RESULTS
The mean age of the subjects was 13.7 years for the middle school students, and 16.6 years for the high school students. The gender and grade distributions in the middle and high school students were similar. The middle school students reported that they spent more time using electronic devices (p<0.001) or watching TV (p<0.001) than high school students. More than 60% of middle and high school students consumed convenience food at convenience stores without statistical difference between the two groups. The main reason for consuming convenience food from convenience stores was its convenience followed by taste in both groups. Despite the high frequency of consuming convenience food, the students rarely checked the nutrition labels at the time of purchase. On the other hand, they were still most concerned about the nutritional value of the convenience foods when they consumed convenience foods. The most frequently consumed convenience food was ramyon in both groups. Significant positive correlations were observed between the frequency of consuming convenience food at convenience stores and lifestyle factors for the middle school students, including monthly allowance, time for using electronic devices, and number of private lessons. For the high school students, however, the only monthly allowance had a significant positive correlation with the consumption.
CONCLUSIONS
Adolescents are increasingly exposed to convenience foods and relevant nutritional issues are a concern. Therefore, a dietary environment that is adequately formed for the healthy development of youth as well as systematic nutrient education that is appropriately designed for both middle and high school students is required.

Daily Water Consumption and its Contribution to Calcium Intake in Korean Adults: Eun Sun Park, Yeon Kyung Lee, Mi Hyun Kim, Mi Kyeong Choi; Korean J Community Nutr 2019;24(1):18-23. Published online February 28, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.1.18

Abstract PDF PubReader

OBJECTIVES
Although water is essential for life and can supply essential minerals, studies that evaluate calcium intake through drinking water are limited. The aim of this study was to assess calcium contents of natural mineral water (NMW) and its possible contribution to calcium intake in healthy adults.
METHODS
This study examined water consumption in 640 Korean adults with selfselected diet, analyzed the calcium content of 10 different brands of bottled NMWs sold in Korea, and assessed the amount of calcium intake from drinking water and its daily contribution to the recommended nutrient intake (RNI) of calcium.
RESULTS
Mean calcium content in 10 bottled NMWs was 20.9 mg/l. Daily water intakes from food composition database and calculated using energy intake based on 0.53 ml/kcal were 957.2 ml and 1109.8 ml for men and 848.3 ml and 951.6 ml for women, respectively, with a significant difference by gender (p < 0.001). Daily drinking water intake was significantly higher among men than women (1203.9 ml vs. 1004.3 ml, respectively, p < 0.001). Daily calcium intakes from foods were 564.0 mg for men and 534.2 mg for women. Daily possible calcium intakes from drinking bottled water were 25.2 mg for men and 21.0 mg for women (p < 0.001). The contribution of daily calcium intake from drinking bottled water to RNI of calcium was 3.3% for men and 2.9% for women without significant difference.
CONCLUSIONS
One half of the daily total water intake was consumed as drinking water, and possible calcium intake through drinking water was about 3% of RNI.

Analysis of the Difference in Nutrients Intake, Dietary Behaviors and Food Intake Frequency of Single- and Non Single-Person Households: The Korea National Health and Nutrition Examination Survey (KNHANES), 2014–2016: Na Yeon Kang, Bok Mi Jung; Korean J Community Nutr 2019;24(1):1-17. Published online February 28, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.1.1

Abstract PDF PubReader

OBJECTIVES
This study was performed to compare the dietary life of single- and non single-person households in the Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
A nationally representative sample of 20,421 19-64-year-olds who had 24-hour recall data was taken from the 2014-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Single- and non single-persons were compared for nutrient intake, dietary behaviors, food consumption patterns, nutrition education and confirm nutrition label.
RESULTS
The dietary intakes of dietary fiber and iron were lower in single-person households than in non single-person households. The lower the level of education and income, the lower the nutrient intake of single-person households. In the case of those aged 19 to 29, the breakfast skipping rate was higher in single-person households than in non single-person households. The higher the education level, the higher the breakfast skipping rate and the eating out frequency in the single-person households. In the food intake survey, the frequency of healthy food intake in single-person households was much lower than that of non single-person households. The confirmation rate of nutrition labeling was lower in single-person households than in non single-person households.
CONCLUSIONS
This study shows that single-person households have poorer health-nutritional behaviors than multi-person households. Therefore, a nutrition education program based on the data of this study needs to be developed for health promotion of single-person households.
