OBJECTIVES
An association between dietary patterns and mental health in children has been suggested in a series of studies, yet detailed analyses of dietary patterns and their effects on ADHD (attention deficit hyperactivity disorder) are limited.
METHODS
We included 4569 children who had dietary intake data as part of the CHEER (Children's Health and Environmental Research) study conducted nationwide from 2005 to 2010. We assessed ADHD (Attention Deficit Hyperactivity Disorder) by the DuPaul's ADHD Rating Scales and dietary intake by a semi-quantitative food frequency questionnaire. Using intake data, we constructed five dietary patterns: “Plant foods & fish,”“Sweets,”“Meat & fish,”“Fruits & dairy products,” and “Wheat based.” RESULTS: The overall proportion of ADHD was 12.3%. Boys (17.8%) showed a higher rate of ADHD than girls (6.5%). The total intake of calories (85 kcal) and plant fat (2g) in the ADHD group was significantly higher than that of the normal group. ADHD was significantly negatively associated with dietary habits such as having breakfast and meal frequency, and positively associated with eating speed, unbalanced diet, overeating, and rice consumption. Regarding dietary patterns, the “Sweets” category was relevant to high ADHD risk (OR 1.59, 95% CI: 1.18, 2.15 for Q5 vs. Q1) in a linear relationship. An inverse, non-linear association was found between “Fruits & dairy products” and ADHD (OR 0.55, 95% CI: 0.39, 0.76 for Q4 vs. Q1).
CONCLUSIONS
Our study confirms both positive and negative associations between diet and ADHD in elementary school age children. Moreover, linear or nonlinear associations between diet and ADHD draw attention to the possible threshold role of nutrients. Further studies may consider characteristics of diet in more detail to develop better intervention or management in terms of diet and health.

The Development of a Nutrition Education Program for Low-income Family Children by applying the Social Cognitive Theory and Health Belief Model
Saes Byoul Lee, Yu Ri Jeong, Hyo Jin Ahn, Min Ji Ahn, Su A Ryu, Nam E Kang, Se Young Oh
Korean J Community Nutr 2015;20(3):165-177.   Published online June 30, 2015
DOI: https://doi.org/10.5720/kjcn.2015.20.3.165
AbstractAbstract PDFSupplementary MaterialPubReader
OBJECTIVES
Based on individual and environmental characteristics of low-income children, we developed a nutrition education program for school-aged children from low-income families according to effective use in social welfare centers.
METHODS
We conducted in-depth group interviews to assess program needs in 28 participants, 10 low-income school-aged children and 9 of their care givers, 9 social workers and 9 care-givers. Theoretical backgrounds of our program were heath belief model and social cognitive theory considering motivation, action and environment characteristics.
RESULTS
Based on the findings of this qualitative study, we developed major program themes and contents. Five selected key themes were 'balanced diet', 'processed food', 'food hygiene and safety', 'Korean healthy traditional diet', and 'family cooking' to induce changes in dietary behaviors. Main findings of in-depth group interviews included 'child's active participation', 'simple and easy to understand messages', and 'environmental constraints' such as a lack of child care at home, limited budget of social welfare centers, and less qualified educators for nutrition and health. Each lesson was constructed as a 1-hour program particularly emphasizing activity-based programs, including cooking and teamwork exercises. Program contents in each session consisted of activities that could induce outcome and value expectations, self-efficacy, perceived benefits, and barriers and cues to actions regarding diet behavior.
CONCLUSIONS
We developed a nutrition education programthat is rarely available for low-income children in Korea, considering theoretical bases. Further studies are needed to validate our program.

Associations between Serum 25-hydroxyvitamin D and Consumption Frequencies of Vitamin D Rich Foods in Korean Adults and Older Adults
Areum Yu, Jihye Kim, Oran Kwon, Se Young Oh, Junghyun Kim, Yoon Jung Yang
Korean J Community Nutr 2014;19(2):122-132.   Published online April 30, 2014
DOI: https://doi.org/10.5720/kjcn.2014.19.2.122
AbstractAbstract PDFPubReader
OBJECTIVES
This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults.
METHODS
Subjects were 10,374 adults and 2,792 older adults participating in the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research.
RESULTS
The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (> or = 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk.dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream.
CONCLUSIONS
Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

Validation of Food Security Measures for the Korean National Health and Nutrition Examination Survey
Kirang Kim, Seo Ah Hong, Sung Ok Kwon, Bo Youl Choi, Ga Young Kim, Se Young Oh
Korean J Community Nutr 2011;16(6):771-781.   Published online December 31, 2011
DOI: https://doi.org/10.5720/kjcn.2011.16.6.771
AbstractAbstract PDFPubReader
The objective of this study was to assess the reliability and validity of food security measures, which was developed based on the US household food security survey module (US HFSSM) with content validity in the Korean population. The reliability and validity were assessed by internal consistency, construct validity and criterion-related validity. The study included 446 households. Among those, 46.2% were households with children. The proportion of food insecure households was 33.3%. Among those, 35.4% and 64.6% households were food insecure with hunger and without hunger, respectively. The Cronbach's alpha coefficients were 0.84 and the infit value by the Rasch model analysis ranged from 0.68 to 1.43. The scale item response curves by food insecurity severity explained well the nature and characteristics of food security, indicating the highest proportion of "yes" for the items on diet quality, followed by those with diet quantity. The result of criterion-related validity showed that food insecurity status was significantly related in a dose-response manner with the household income level, food expenditure, subjective health state, subjects' educational level. Household food security status was also related to dietary diversity regarding protein foods, fruits and fruit juice, and milk and dairy product. These findings suggest that the food security instrument is reliable and valid and would be used to assess food security status in the Korean population.

Changes of Eating Habits of the Residents of Taean, Korea after the Herbei Oil Spill Accident Based on Focus Group Interviews
Ji Hyun Park, Sung Ok Kwon, Woo Cheol Jeong, Jong Il Huh, Se Young Oh
Korean J Community Nutr 2011;16(4):466-472.   Published online August 31, 2011
DOI: https://doi.org/10.5720/kjcn.2011.16.4.466
AbstractAbstract PDFPubReader
Hazardous chemicals, such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs) and heavy metals, are known as being harmful to human health were included in oils released by the Herbei Spirit Oil Spill accident in December 2007. To investigate changes of eating habits by the exposure to harmful substances, we conducted 5 focus group interviews for residents at Taean coast areas, who had experienced the oil spill accident. Participants included 46 women (mean age: 57.2 +/- 10.9) who were mainly responsible for preparing family meals. Focus group discussions were audio-taped, transcribed and categorized by themes. Participants expressed more frequent illness symptoms such as dizziness, vomiting, visual loss, and skin diseases after the accident. They mentioned that their worries about economic hardship and worsened health status since the accident induced mental problems, such as depression about their children. Regarding eating habits, participants reported less intakes of fishes and meats and relatively more intakes of vegetables and kimchi due to the lack of household incomes after the accident. Although the participants had been used to collecting or catching fish or shellfish for their consumption previously, they mainly purchased these foods from local markets after the accident. Changes of eating habits induced by the accident included drinking boiled water and having steamed or fried seafood rather than raw seafood. Changes of food intakes occurred less frequently in older adults due to their long-term fixed eating habits, although they felt uncomfortable for having raw fish. The findings of this study clearly present that the exposure of hazardous substances by the oil spill accident had a significant impact on changes in eating habits besides economic, physical, and mental problems among the residents in Taean. Continuous health and nutrition monitoring and support are needed.

Estimated Iron Intakes from Simulated Fortification to Selected Grain Products in the Korea Food Supply
Hae Rang Chung, Min Ji Hong, Rafael Perez Escamilla, Se Young Oh
Korean J Community Nutr 2006;11(6):808-813.   Published online December 31, 2006
AbstractAbstract PDF
Until now, South Korea does not have either fortification or enrichment program as intervention tools, although the addition of micronutrients to foods is for the most part not regulated. The aim of this study was to determine which scenario would most effectively reduce the proportion of the population with low iron intake while not putting other population groups at risk of excessive intakes. In order to investigate potential dietary consequences of iron fortification, we analyzed 2 day dietary record data (n=3,955) from the 2001 National Nutrition Surveys. The Proportion of the population consuming dietary iron less than the estimated average requirement (EAR) ranged from 12.4~87.5% depending upon gender and age group. Iron fortification at the level of 100% of Recommended Intake (RI) per 100g to breads and instant or dried noodles was estimated to result in a 15% decrease of proportion of those with iron less than EAR, while putting 1.4 % of the population greater than the Upper Limit (UL). Iron fortification appeared to be the most effective for the 15~19 year old age group, showing 39% reduction of iron intake insufficiency. The results suggest that carefully designed fortification or enrichment to staple foods may contribute to increase dietary iron intakes of Koreans, especially for the young population with a high prevalence of iron inadequacy. As the estimation in this study was based solely upon dietary intake data, iron intake from supplements should be considered in further studies.

Se Young Oh, Kyung A Kim, Hye Eun You, Hae Rang Chung
Korean J Community Nutr 2004;9(6):725-733.   Published online December 31, 2004
AbstractAbstract PDF
It was well received that well grounded behavioral theories were important in the development of effective nutrition education programs, but there are only a few programs available for Korean women. The objective of this study was to develop nutrition education programs for childbearing-aged women in Korea. Based on the findings of the needs assessment for the program and theoretical backgrounds, we developed behaviorally oriented tailored nutrition education program including motivation (MT), modifying (MD) and maintenance (MA) stages. The key concepts of the stages were motivation promotion for MT, increasing behavioral capabilities for MD, and strengthening self-management and building favorable environmental condition for MA. The education program was intended to be need in individual nutrition counseling, but it could be well used for group education by developing materials using the relevant contents. The primary users of the program were nutrition educators, however it could be also used by clients as needed. The introductory chapter provided dietary assessment tools and nutrition education tips. MT chapter included subjects such as nutritional status screening, costs of inappropriate nutrition and weight management, benefits of eating right, and activities for motivation promotion. MD stage chapter dealt with topics of healthy weight, knowledges and skills for better eating habits and physical activity status, and activities related to setting tailored behavioral objectives. MA stage focused on facilitating self management skills and building helping relationships. Each stage underlined activities using various educational tools in order to promote active participation of the client (s). For better use of this program, it was recommended to conduct program validation study.

Development of a Semi-Quantitative Food Frequency Questionnaire for Pre-school Children in Korea
Young Lim, Se Young Oh
Korean J Community Nutr 2002;7(1):58-66.   Published online February 28, 2002
AbstractAbstract PDF
The purpose of the study was to develop and evaluate the reliability of a semi-quantitative food frequency questionnaire (SFFQ) intended to measure mainly nutrient intake (energy, protein, fat, calcium and iron) related to growth in pre-schoolers in Korea. Based on foods with up to 90 cumulative percent contribution of the 5 nutrients, we developed a SFFQ for 86 foods. In order to evaluate the reliability of both nutrient and food intakes, caregivers of a sample of 101 children aged 4 to 6 years completed the SFFQ repeatedly at 3 month intervals. There were small differences in the nutrient intakes assessed by the SFFQ ranging from 0.55% to 9.91%. There were no significant differences in nutrient values calculated from the repeat questionnaires, except in the case of niacin and vitamin C. The Pearson correlation coefficients of most of the nutrients ranged form 0.54 to 0.75 (mean = 0.66). When energy intake was adjusted, there was approximately a 0.2 decrease in the correlation coefficient of most nutrients, due to the high correlation of energy intake with other nutrients (r=0.7-0.9). The amount of food intake differed by 0.1 to 66.4% (mean = 17.5%), depending on the food item. Out of 86 foods, 74 foods (86%) showed less than a 30% difference in intake and 30 foods (35%) showed less than a 10% difference. Only 6 (7%) out of the 86 foods presented statistically significant differences in intake. The Spearman correlation coefficients of most food intakes assessed repeatedly by the SFFQ ranged from 0.4 to 0.7. Reproducibility of the nutrient and food intakes found in this study was better or similar to those found in cases of Korean adults. Therefore, the SFFQ developed in the present study can be a useful tool to assess the dietary intake of pre-schoolers in Korea.

Se Young Oh, Mi Ran Cho, Jean O Kim Rim
Korean J Community Nutr 2000;5(4):615-623.   Published online December 31, 2000
AbstractAbstract PDF
Under the assumption that people go through stages in making dietary behavior change, this study was attempted to apply the stages of a change model for fat intake by examining the associations of social psychological variables with stages of change in dietary fat reduction. Derived from social psychological theories, 10 social psychological variables on motivational beliefs(6), social influence(3) and self-efficacy(1) related specifically to selecting every day diets low in fat were constructed. Fat and energy intakes were assessed by a short form semi-quantitative food frequency questionnaire. The associations of stages of change with motivational beliefs, social influence, and self-efficacy variables and energy and fat intakes were assessed in 333 female adults from large cities in Korea. Dietary stage groups differed significantly on most of the social psychological variables in ways predicted by theory. Motivational factors that lead to a psychological state of readiness to take action were important in the early stages of the dietary change process. Social influences were more important in the stages as people decide to take action. Self efficacy and motivational beliefs, particularly, reduction of perceived barriers were important in maintaining fat reduction behavior. The results of our study indicate differences in stages of change in fat reduction behavior in terms of nutrient intakes and social psychological correlates and suggests that adding a time dimension to social psychological models increases our understanding of dietary change, which assist us in designing nutrition education interventions that are more appropriately targeted by stage of change.

The Experience and Intention of Health Food Use among Middle-aged Men in Urban Areas
Hwa Suk Song, Se Young Oh
Korean J Community Nutr 2000;5(2):193-200.   Published online July 31, 2000
AbstractAbstract PDF
This study examined the experience and intention of health food use regarding the different type of health foods among 201 middle-aged Korean men form urban areas. Based upon the results of a prestudy, health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured heath food supplements(MHFS). compared with the4 case of health food experience, the similar proportion of the subjects were intended to use CM( 70%) and MHFS( 40%), yet the smaller proportion of them had the intention for TF(46%) and VMS(52%). Our subjects mainly obtained information on CM and TF from social networks, such as families, relatives, friends and neighbors and VMS and MHFS from mass media. Expected effects of health food consumption were different by the type of health food. The most positive expected effects were found in CM, followed by VMS. However, there was weak evidence for the positive effects of the TF and MHFS. Upon the consumption of health foods, our subject appeared to expect to their body energy to increased and body functions to be improved in general. Multivariate analyses indicated the importance of expected effects of health food consumption and aging symptoms as determinants of future health food use. Experience was rarely associated with intention in health food use. This study suggests that educated middle-aged Korean men may have a rational attitude toward health food use. Regarding different attitudes and behavior toward the different type of health foods, further research should consider the nature of each type of health foods. The limitations of this study are also discussed.

Within-and between-person Variation in Nutrient Intakes by the Korean Elderly
Myung Hee Hong, Se Young Oh
Korean J Community Nutr 1998;3(3):423-429.   Published online August 31, 1998
AbstractAbstract PDF
This study examined within- and between-person variation in nutrient intakes in order to estimate the degree of precision in dietary assessment among 37 males and 46 females whose mean age was 70.4 years old. To collect dietary data, each subject was interviewed 5 or 6 times using a 24-hour recall method during a 3 month period. Within-person variation ranged from 23.5% to 101.2%. Lower values of within-person variation were observed in energy, carbohydrated, protein and phosphorous while higher value was observed in vitamin A. Between person variations of nutrient intakes ranged 12.6-23.5% in most nutrients. With 1 day dietary data, observed nutrient intakes were estimated to within 6-25% of the group's usual9true) intakes and 52-198% of the individuals' usual intakes. The values of these maximum percentage deviations became smaller when the number of dietary recalls increased. The results of this study suggest that the Korean elderly subjects appear to have a slightly less diverse diet compared to young Korean women. Within persons, intakes of nutrients largely from animal sources were more variable for the Korean elderly than for their counterparts in Western countries. This study also implies that commonly used 1 day dietary study may be appropriate for assessing group means of nutrient intakes, but clearly not appropriate for assessing individual's nutrient intakes.
