Comparison of Serum Adiponectin Levels According to Body Mass Index and Dietary Behaviors of Female University Students in Seoul: Mi Joung Kim, Hyun Young Jun, Hye Bog Rha; Korean J Community Nutr 2013;18(4):354-364. Published online August 31, 2013; DOI: https://doi.org/10.5720/kjcn.2013.18.4.354

This study was conducted to determine whether dietary factors could be related with serum adiponectin concentrations in 243, year-three female university students living in Seoul. The mean of body mass index (BMI) and adiponectin levels of all subjects were 20.17 kg/m2 and 11.07 microg/ml, respectively. When the subjects were divided into 3 groups based on BMI (underweight: < 18.5, normal: 18.5 < or = < 23, overweight and obesity: > or = 23), serum adiponectin levels in underweight group was significantly higher than that in 'normal' or 'overweight and 'obesity' groups. Also when the subjects were divided into two groups by mean adequacy ratio (MAR), serum adiponectin concentration of the high MAR group (MAR > 75) was slightly higher than that the low MAR group (MAR < or = 75). Serum adiponectin levels showed a negative correlation with body weight (p < 0.01) or BMI (p < 0.001) and a positive correlation with intakes of of animal or total protein (please clarify) or vegetable protein.Among the dietary behaviors, serum adiponectin levels of females who answered 'yes' to the question about 'eating breakfast' was significantly higher than that of those who answered 'sometimes' or 'No' (p < 0.05) and serum adiponectin levels were higher among those who reported higher fruit intakes. Overall, our results suggested that healthy lifestyle including acceptable BMI, eating breakfast and higher fruit consumption might play an important role in the prevention of obesity and enhancement of blood adiponectin levels.

The Comparison in Daily Intake of Nutrients and Dietary Habits of College Students in Busan: Myung Soo Ko; Korean J Community Nutr 2007;12(3):259-271. Published online June 30, 2007

Abstract PDF: The purpose of this study was to investigate the dietary habits and daily intake of nutrients in college students. This survey was conducted using a self-administered questionaire. The average heights and weights were 173.5 cm and 72.3 kg of male students and 161.8 cm and 57.2 kg of female students. The average of BMI was 24.2 kg/m2 of male and 21.9 kg/m2 of female, and the value of male students was higher than the value of female students. The response to the daily meals was 54.6% for '2~3 times/week'. The regularity of mealtime was 41.7% for irregular and the frequency eating after nine was 45.7% for '5-6 times/week', respectively. The repast was 72.2% for 'overeating and little eating' and was a significant difference of male and female students (p < 0.05). The eating rate was higher '10 ~20 min'. As for breakfast food eaten, skipping breakfast was 23.6% for 'no/week' and female students were higher than male students (p < 0.05). The frequency of snacks was 36.0% for 'nothing' of males students and 34.8% for '3- 4 times/week' of female students (p < 0.05). The type of snack was a significant difference of males and females students (p < 0.01), and was the highest 75.0% for carbonated drinks of males and 37.5% for snacks of females. The eating due to stress solution was a significant difference of male and female students (p < 0.01), and was the highest 23.0% for 'frequency' of males and 44.7% for 'sometime' of females. As for food intake of male and female students, the meat intake was 66.7% for 'everything of male and female students. The fish intake was 68.1% for '1- 2times/week'. The milk, milk products, eggs and beans were each 40.3%, 58.3%, 56.9%, 47.2% for '1-2 times/week' (p < 0.05). The fat intake was 55.6% for '1~2 times/week'. The average consumption of energy was 58% of male and 67% of female of estimated energy requirement (EER). Their mean ratio of carbohydrate : protein : fat was 57 : 15 : 28 of all subjects. The mean intakes of vitamin C and folic acid were 70% and 51% of males and 62% and 52% of females of recommended intake (RI). The mean intakes of Ca, P, Fe and Na were 71%, 140%, 146% of males and 72%, 122%, 76% of female of RI and 273% of males and 233% of females of adequate intake (AI). Therefore, nutritional education is necessary for college students to establish physicall and mentall optimal health conditions through nutritional intervention.

Factors Affecting Bone Mineral Status of Premenopausal Women: Se In Oh, Hang Shin Lee, Mee Sook Lee, Cho Il Kim, In Soon Kwon, Sang Chul Park; Korean J Community Nutr 2003;8(6):927-937. Published online December 31, 2003

Abstract PDF: This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited the Health Promotion Center for health examinations volunteered to participate in this study. They were divided into two groups according to their bone status as shown by their T-scores: a non-osteoporotic group and a osteoporotic group. The results are as follows: The mean BMDs of the lumbar spine and femoral neck were 1.21 +/- 0.02 g/cm2 and 0.97 +/- 0.04 g/cm2, respectively. The BMD levels of the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.001, respectively). The heights of the women in the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.01) however, their body weights did not show any significant differences although they tended to be lower. The mean daily intake of energy was 1720 +/- 52 kcal. When the nutrient intake was compared with the Korean recommended dietary allowances (RDA), calcium, Fe, vitamin A and riboflavin intakes were lower than the RDA. Their was no significant difference in the nutrient intake of the non-osteoporotic group and osteoporotic group except for the intakes of protein, fat and niacin. Their was no significant difference between the non-osteoporotic group and the osteoporotic group and all were within the normal range. However, the serum alkaline phosphatase level of the osteoporotic group was significantly higher than that of the non-osteoporotic group (p < 0.001). Height measurements showed positive correlations with lumbar spine bone mineral density (LBMD, r = 0.332, p < 0.01) however there was no correlation with femoral neck bone mineral density (NBMD). Age, age at menarche, body weight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r = 0.236, p < 0.05; r = 0.274, p < 0.05). Serum levels of calcium and phosphorus showed negative correlations with LBMD (r = -0.698, p = 0.0001; r = -0.503, p = 0.0001, respectively). The results suggested that the BMD of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective ways to minimize bone loss would be have a higher intake of niacin and vitamin C rich foods and engaging habitually in physical activity may have a beneficial effect on BMD in the premenopausal period.

The Relationship between Serum Cholesterol Levels and Dietary Fatty Acid Patterns, Plasma Fatty Acids, and Other Lipid Profile among Korean Adults: Jeong Sook Kim, Youn Kyoung Suh, Hyung Sook Kim, Kyung Ja Chang, Haymie Choi; Korean J Community Nutr 2003;8(2):192-201. Published online April 30, 2003

Abstract PDF: The purposes of this research were to assess dietary fatty acid patterns and to elucidate the relationship between the serum cholesterol levels and dietary fatty acid patterns, plasma fatty acid compositions, BMI (body mass index), and other lipid profile. The subjects were 151 adults aged 23 to 80 years, selected from the Outpatient Clinic and Cardiovascular Department of the Seoul Municipal Hospital. Dietary data were obtained using three day food records. Sixteen dietary fatty acids were analyzed using Korean and US nutrient databases. The subjects were divided into three serum cholesterol levels: desirable (< 200 mg/dl, N = 44), borderline-risk (> or = 200 - < 240 mg/dl, N = 35), and high-risk (> or = 240 mg/dl, N = 72) groups. The high-risk group had higher BMI, waist, and waist to hip ratio (WHR) than the desirable and borderline-risk groups. Serum concentrations of triglyceride, LDL cholesterol and LDL/HDL cholesterol ratio were significantly higher in the high-risk group as compared to those in the other two groups. The serum cholesterol levels were highly correlated with BMI (r = 0.435), triglyceride (r = 0.425) and LDL/HDL cholesterol (r = 0.870) ratio. The highest fatty acid intake was from oleic acid (33 - 34% of total fatty acid intakes), which was followed by linoleic acid (27%), palmitic acid (19%), and stearic acid (7%). There was no correlation between the serum cholesterol levels and the dietary fatty acid intakes, polyunsaturated/monounsaturated/saturated fatty acids (P/M/S) and omega6/omega3 ratios. The correlation between plasma fatty acids such as myristic acid, oleic acid, linoleic acid, and docosahexaenoic acid and serum cholesterol levels was also weak.
