Application and Evaluation of Web-based Food Frequency Questionnaire for Korean Adolescents: Jinhee Yum, Seungmin Lee; Korean J Community Nutr 2016;21(5):440-450. Published online October 31, 2016; DOI: https://doi.org/10.5720/kjcn.2016.21.5.440

Abstract PDF PubReader: OBJECTIVES
We previously developed a dish-based semi-quantitative food frequency questionnaire (FFQ) for Korean adolescents and reported that it had reasonable reliability and validity. The objective of the current study was to construct a web-based dietary evaluation system applying the FFQ for Korean adolescents and examine its applicability in the context of reliability and validity.
METHODS
A web-based food frequency questionnaire system was designed using a comprehensive approach, incorporating not only dietary data survey but also up-to-date nutrition information and individualized eating behavior guidelines. A convenience sample of 50 boys and girls aged 12~18 years agreed to participate in the study and completed the FFQ twice and 3 days of dietary recall on the developed website during a two-month period. The FFQâ€™s reliability and validity was examined using correlation and cross classification analysis. We also measured participantsâ€™ subjective levels of the web siteâ€™s usability, visual effect, understanding, and familiarity.
RESULTS
Spearman correlation coefficients for reliability ranged from 0.74 (for vitamin A) to 0.94 (for energy). From cross-classification analyses, the proportion of subjects in the same intake quartile was highest for energy (82.0%) and lowest for vitamin A (56.0%). With regard to validity analysis, Spearman correlation coefficients ranged from 0.34 (for fiber) to 0.79 (for energy). The proportions of subjects in the opposite categories between the first FFQ and 3-day diet recall data were generally low from 0.00% (for fat) to 36.2% (for sodium). Average subjective levels of the websiteâ€™s usability, visual effect, understanding, and familiarity were all found to be over 4 points out of 5 points.
CONCLUSIONS
The web-based dietary evaluation system developed can serve as a valid and attractive tool for administering FFQ to Korean adolescents.

Development and Evaluation of a Nutrition Education Website for the Prevention and Management of Childhood Obesity: Miyong Yon, Chan Park, Kwan Hee Yoo, Taisun Hyun; Korean J Community Nutr 2012;17(4):390-406. Published online August 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.4.390

Childhood obesity has rapidly increased worldwide and is one of the most serious health problems in this age group. In order to prevent and manage childhood obesity, we developed a nutrition education website. The website consisted of three parts. The first part was made for self-assessment with regard to obesity index, dietary habits, food frequency, dietary attitude, nutrition knowledge, nutrient intake, energy expenditure, and the stage of behavioral change, and tailored messages and advice according to the assessment results. A total of 612 real-size food photos as well as a nutrient database of 3,346 foods and 541 dishes were created to help children estimate nutrient intakes accurately. In addition, an energy expenditure database of 156 activities for children was established to calculate calorie consumption. The second part was made for setting long-term and short-term goals and keeping track of the changes in energy intake and expenditure in one's own page. The third part was made for education. Various types of nutrition information were provided; texts, pictures, calculators and games. The readability and design of the website were evaluated by 46 obese children. Usefulness, design and readability of the website were found to be desirable for children. This website is expected to be used by an obese child alone or with parents or nutrition teachers in order to control body weight through healthy dietary habits and physical activities. In addition, a non-obese child can also use this website for maintaining healthy dietary habits and preventing obesity.

Intake Pattern and Needs Assessment for the Development of Web-Contents on Health Functional Foods according to Age of Adults: Jeong Ohn, Jung Hee Kim; Korean J Community Nutr 2012;17(1):26-37. Published online February 29, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.1.26

Abstract PDF PubReader

This study was done to analyze the consumption patterns of health functional food (HFF) as well as to perform needs assessment for the development of web-contents on HFF according to age of adults. The subjects were 238 male and female adults, divided into 4 groups by their age. This study collected all information by self-administrated questionnaires. The awareness on HFF was high in the older adults. The younger adults showed more negative responses to reliability and safety on HFF. The main reason for the consumption of HFF was to supplement nutrients and to prevent diseases. The main types of HFF consumed by adults were nutritional supplementary food, red ginseng products, and glucosamine products. There was higher consumption of nutritional supplementary food in the younger adults and glucosamine products in the older adults. Internet users had low level of satisfaction, with tendency to complain poor contents, reliability, difficulties in searching as problems of the pre-existing HFF websites. As useful methods for provision of information on HFF, most adults wanted general information, articles written by experts and videos. They also wanted to know the safety and side effects of HFF. Requirement of contents composition were various in-depth information, clear indication of citation, fresh updated data while that of display composition was easily-findable, uncomplicated, allowing mutual exchange of communication through bulletin board. These results can be used as basic data that reflect the consumer's needs for developing HFF web-contents according to age of adults.

Published online February 28, 2010

Abstract PDF: This study was carried out to reduce children's sugar, natrium and fat intakes and establish their healthy lifestyle. To achieve these goals, we developed an educational web site and an e-learning system. The targets of this web site are children, parents and educators. This site has various information about sugar, natrium and fat, and has special menus for each target: such as the 'Let's study' for children, 'Guides for child's eating' for parents, and 'Educational softwares, Lesson plans/materials, and Textbooks/Teaching guides' for educators. We developed three nutrient characters and applied them to the web site. We provided information in the form of texts, images, flash and sounds. This site has special boards in 'Nutrition cafe' menu to interchange information or their successful stories between the connecters. We developed an e-learning system with two courses. One is for junior elementary students and the other is for senior students. Children can study each nutrient step by step in a course according to their academic ability and concern. Also, they can evaluate their academic achievement in this system, which was uploaded into 'Let's study' in children menu in the web site. Conclusively this web site and e-learning system could contribute to reducing children's sugar, natrium and fat intakes by helping children study them systematically and effectively by on-line system. We expect this e-learning system would be a new nutrition education system to make nutrition education more active.

Evaluation of a Nutrition Education Website for Children: Sun Hee Kim, Taisun Hyun; Korean J Community Nutr 2006;11(2):218-228. Published online April 30, 2006

Abstract PDF: This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood (http://ifood.or.kr)' for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were "Interesting games" for 35.8%, "How can I cook?" for 17.8%, "How can I become slim" for 16.4%. This website might be more attractive by providing a "greater variety of contents in detail", "more music, motion pictures and images", "more interesting games". After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that "ifood", a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

Published online August 31, 2004

Abstract PDF: For the purpose of developing 'Web-Based Nutritional Education Program', this study did instructional analysis, analysis of entry behaviors and learner characteristics to select instructional contents for nutritional education program for junior/senior high school students. Survey questionnaires were distributed from October 21, 2002 to October 26, 2002 to a total of 564 junior/senior high school students in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. As a result of the curriculum analysis of 'Techonolgy-Home economics', subjects related with 'food and nutrition' in the 7th educational course study result, lessons including the contents of food and nutrition were 'nutrition and meal of adolescent' in 7th grade, 'family meal management' in 9th grade and 'practice of home life' in 10th grade. According to the curriculum analysis, 'nutrition' and 'food' were chosen for the superior subjects of nutrition education program and four subordinate subjects per superior one were developed. Then, entry behaviors and learner characteristics were analyzed: life characteristics, internet usage, anthropometrics data and nutritional knowledge. Students were interested in using computer and preferred passive activity to dynamic activity. According to the analysis of internet usage, WBI for students should composed active parts such as game, moving image, immediate reply and follow-up by e-mail, bulletin board and community activity. Students' BMI were in normal range but they were lacked nutritional knowledge. We wrote performance objectives that were specific behavior skills to be learned, the conditions under which they must be performed and the criteria for successful performance. The next step for developing the WBI nutrition education program would be based on the results mentioned above.

Setting Instructional Goals for Nutritional Education Program Through an Analysis of Problems Identified in Junior/senior High School Students: Il Sun Yang, Hae Young Lee, Hye Young Kim, Yeo Hwa Kang; Korean J Community Nutr 2003;8(4):495-503. Published online August 31, 2003

Abstract PDF: For the purpose of developing 'Web-Based Nutritional Education Program', this study analyzed nutritional problems of junior/senior high school students and set appropriate instructional goals for nutritional education program. Survey questionnaires were distributed from October 21,2002 to October 26, 2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. According to the survey results, three student groups (male and female students at junior high schools and female students at senior high schools) had lower than an ideal body weight. In case of their Basal Metabolic Indices (BMI), the female students and junior high school students showed a tendency to be underweight, while the other three student groups were within the normal range. The result of the survey showed that all four groups of students showed a deficiency in nutrient intake of calories, calcium and thiamin when compared with Korean RDA. Particularly, in the case of the female students at senior high schools, the deficiency of iron intake was a problem. The survey about food attitudes and food habits of the students showed that the senior high school students had more problems when compared with their junior high school counterparts (p < .001). Therefore, the instructional goals of nutritional education program were set as follows: 1) To improve the level of understanding and the perception of junior and senior high school students about the importance of a dietary lifestyle. 2) To change food attitudes and nutritional knowledge related to individual dietary 1ifestyle, so as to maintain good health through the enhancement of the students' physical activities. We found out that it is critically important to factor in the existing problems of food attitudes and food habits, as well as nutrient intake among junior and senor high school students when setting objectives for nutritional education programs.

Development of a Nutrition Education Website for Children: Taisun Hyun, Miyong Yon, Sun Hee Kim, Nan Hee Kim, Suk Mi An, Sun Mi Lee, Hyun Jung Chi, Myeong Hee Sun, Chun Hwa Oh, Seon Hee Wang, Mi Kyung Hong; Korean J Community Nutr 2003;8(3):259-269. Published online June 30, 2003

Abstract PDF: The purpose of this study was to develop a nutrition education website for children, especially those around the 4th-6th grade levels. Among the already existing websites providing nutritional information for children, 7 websites with comparable amounts of information were evaluated in terms of their topics, credibility, content, ease of use, and aesthetics. In addition, a survey was conducted to assess the need for nutrition information among 305 elementary students. The food pyramid was the topic offered most often on those websites. Information on nutrients, digestion, food safety, nutrition labeling, and healthy eating habits were available on the websites. Some of those websites also provided games or quizzes to attract the children's interest. However, seine of the websites did not give any information on the person responsible for providing the information, which is most important in determining the credibility of the website. Other problems were that some information was too difficult for children, and some of the websites did not provide a way to search for information. According to the survey results, the topics that children wanted to know about were 'desirable weight', 'cooking', 'correct food choice', 'weight control method', 'calories consumed during exercise' but, they did not have a high interest in 'asking questions', 'books with nutrition messages', 'under weight', 'negative effect of weight control' and 'helping hungry children'. Based on these results, we developed a new nutrition education web-site, ifood' (http://ifood.or.kr). We focused on helping children develop healthy eating habits by providing information which is easy and practical for children. However, we neither included the program to assess their dietary intake, nor provided entertaining background sounds, which children like. Also, the game section is composed mainly of quizzes. Therefore, we need to further develop exciting games to teach nutrition to children. In the near future, the newly developed website should be evaluated by children regarding understandability and coverage of the contents as well as usability and design, and then revised to improve the educational effect.
