BACKGROUND/OBJECTİVES: It is important to determine Dysfunctional eating behaviors such as dietary restraint and overeating tendencies in order to provide weight management and acquire the right habits in children. The purpose of this study was to test the reliability and validity of Dutch Eating Behaviour Questionnaire Children (DEBQ-C) with Turkish preadolescent children. MATERIALS/METHODS: This research included 440 preadolescents (9.3 ± 6.9 years and 235 girls, 205 boys). The instrument is divided into three subscales, each with 20 items. Emotional eating, restrained eating, and external eating are the three subscales. Confirmatory factor analysis (CFA) was used to assess the construct validity of the Turkish version of the DEBQ-C, and Cronbach α values were computed to evaluate the subscale reliabilities. There were 20 observable variables and three latent variables in the hypothesized model. RESULTS: Fit indices for the hypothesized model were good (×2/degree of freedom = 1.96; root mean square error of approximation = 0.05; comparative fit index = 0.95; goodness of fit index = 0.93). These findings revealed that the Turkish version of the DEBQ-C has a factor structure that was identical to the three-factor structure of the original scale. The Turkish version of the DEBQ-C subscales has internal consistency coefficients ranging from 0.72 (external eating) to 0.86. (emotional eating). CONCLUSIONS: The DEBQ-C Turkish version is a viable and reliable tool for measuring overeating tendencies in Turkish preadolescents, according to the findings.

Increasing numbers of Korean adults, especially women, are adopting vegetarian diets for various reasons. In this study, the characteristics of vegetarianism among females residing in Seoul were examined. In addition, the dietary habits and eating behaviors between vegetarians and non-vegetarians were investigated. A total of 148 females (73 vegetarians, 75 non-vegetarians) were recruited and questionnaires regarding their demographic characteristics and eating habits were completed. The eating behavior and daily intake of food groups was assessed using the three factor eating questionnaire-R18 (TFEQ-R18) and food frequency questionnaire, respectively. The ages, BMI, education, and religious affiliation were not significantly different between the two groups. More than 30% of vegetarians had followed a vegetarian diet for longer than 24 months. The most common motivations for vegetarianism in study participants were 'health or weight control' (46.6%) followed by 'environmental concerns or animal welfare' (24.7%). Vegetarians had a lower intake of cereals, Kimchi, and soda, but a higher intake of potatoes and sweet potatoes, vegetables, mushrooms, seaweed, and fruits compared to non-vegetarians. Significant differences in eating behavior scores were also found between the two groups; in particular, vegetarians reported higher levels of restrained eating and emotional eating than non-vegetarians. Scores of uncontrolled eating, however, were not significantly different between the two groups. In conclusion, these results suggest that while vegetarianism is associated with healthy dietary habits, it is associated with restrained eating behaviors which may increase the risk of eating disorders in women.

The purpose of this study was to investigate the risk factors of childhood obesity and the characteristics of the parents of obese children. Methods 110 children of 5years old living in Seoul and Kwangju were surveyed by questionnaire about the children(birth weight, birth order, type of feeding, eating behavior, daily habit) and the parents(weight, height, education). The behaviors of mothers about eating restriction were assessed by three factor eating questionnaire(TFEQ). Children's weight and height were examined and the obesity indeces were calculated. Result: 1) The prevalence rate of obesity among 5 years old children was 20.1%, and male had significantly higher prevalence rate. No significant difference was found in birth weight, birth order, and type of feeding between two groups. 2) The obese group showed significantly more cases of "eat rapidly" 3) fathers of obese children were significantly older and showed higher educational levels. No significant difference was found among parental body mass indeces between two groups. 4) Mothers of obese children showed significantly higher scores of cognitive restriction factor and disinhibition factor in TFEQ. There was no difference in hunger factor, The score of mothers TFEQ was significantly correlated with children's obesity indeces. Conclusion : Children's eating behavior and mother attitude about food restriction have influence on children's obesity among 5 years older children.

Objectives : Despite the lack of domestic research, eating alone has been reported to be related to depression. We investigated correlation between eating alone, and depression, among women age 65 and older. Methods : Among women registered in the Korea National Health and Nutrition Examination Survey data, 1,119 elderly in 2014, and 1,189 in 2016, were analyzed. Eating alone and the degree of depression were assessed, using a questionnaire and the Patient Health Questionnaire-9 respectively. The relationship between eating alone and depression, was analyzed using multilevel logistic regression. Results : In 2014 data, eating alone had significant effect on depression, as the explanatory power is increased to 30.4% in a 'three meals eating alone a day' group (${\beta}=0.128$, p<0.05), when the eating alone parameter is added to demographic factors and health characteristics. In 2016, exploitation of 'the frequency of eating alone' variable led to increment of explanatory power to 22.3%, that was not statistically significant. Conclusion : The result of this study suggests that eating alone among women age 65 and older, was a risk factor of depression in 2014, and is becoming a new life pattern as a social and cultural phenomenon in 2016.

Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named 'Rice and kimchi eating' (n = 617), 'Contented eating' (n = 124), and 'Healthy and light eating' (n = 120). The 'Healthy and light eating' group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the 'Healthy and light eating' group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the 'Healthy and light eating' group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the 'Rice and kimchi eating' group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.

The purpose of this study was to provide basic information for developing nutrition education programs for preschool children and their families. The subjects were 291 parents whose children went to daycare centers in Uiwang. The questionnaire contained 15 items for children's dietary habits and six items for parents' nutritional attitudes. The results of frequency analysis of children's dietary habits were as follows: 63.9% of children ate meals regularly, however breakfast (46.4%) was usually skipped; 44.0% of children ate a snack more than twice per day; 56.7% did not have late night meals; 49.5% ate out once to twice per week; 89.7% had dinner with family more than three times per week; and 43.6% had picky eating habits. The percentage of children who did not eat vegetables and seaweed was the highest among other food groups. Intake frequencies were low in fatty foods, instant foods, and fast foods. Some correlations were observed between picky eating habits and other dietary habits by cross-tabulation analysis. Intake frequency of non-picky eating children was lower for late night eating and fatty foods but higher for vegetables and seaweed compared to picky eating children. Parents answered that their nutritional knowledge level was normal (72.2%), and nutritional information was collected using the Internet (36.0%). Nutritional value was the most considered point in meal preparation of parents (43.3%), and the most difficult factor in child's diet management was lack of time due to working (36.1%). Parents cited method of creating a menu (27.0%) and table manners (25.3%) as topics of nutrition education by professionals. Therefore, various nutrition education programs need to be developed to improve healthy dietary habits for children and their families.

BACKGROUND/OBJECTIVES: To determine the weight change trend among the adult Turkish population after 1 yr of the coronavirus disease 2019 (COVID-19) pandemic and factors associated with weight change. MATERIALS/METHODS: This cross-sectional study was conducted between 26 February and 6 March 2021 using an online questionnaire that included questions for sociodemographic variables, eating habits, stress level, and the Three-Factor Eating Questionnaire-R18. Those who weighed themselves 1-2 weeks before the pandemic was declared in Turkey and remembered their weight were invited to participate in the study. Trends in weight and body mass index (BMI) change were calculated. The variables associated with a 1% change in BMI were assessed using hierarchical regression analysis. RESULTS: The study was conducted with 1,630 adults (70.25% female) with a mean age of 32.09 (11.62) yrs. The trend of weight change was found to increase by an average of 1.15 ± 6.10 kg (female +0.72 ± 5.51, male +2.16 ± 7.22 kg) for the first year of the COVID-19 pandemic. The rate of participants with a normal BMI (18.50-24.99 kg/m²) decreased to 51.91% from 55.75%. Consuming an "Increased amount of food compared to before the pandemic" was found to be the independent variable that had the strongest association with a 1% increase in BMI (β = 0.23 P < 0.001). The average change in the BMI was higher in older individuals than in those who were younger. A high stress level was associated with a decrease in BMI (β = -0.04 P = 0.048). CONCLUSIONS: In this study, the factors associated with weight change after 1 yr of the pandemic in the Turkish population was reported for the first time. A high stress level and increased weight gain trend still occur in Turkey after 1 yr of the pandemic.

This study was conducted to provide desirable way on the eating of sugar foods, specifically the differences between dietary attitude, dietary behaviors and intake frequency. Data was collected from 279 middle students in the Incheon region through a self-administered questionnaire. According to the results of the reliability and factor analysis, the dietary attitude, dietary behaviors and intake frequency was 3.52, 2.89 and 2.51, with a Cronbach alpha coefficient of 0.867, 0.789, 0.940 and KMO of 0.899. Factor analysis extracted three components of the sugar preference, which we named dietary attitude (factor 1), dietary behaviors (factor 2), and intake frequency (factor 3). The dietary attitude and dietary behaviors showed a significant difference between sugar preference and non-preference (p < 0.05). Also, intake frequency of sugar food showed a significant differences in chocolate, chocolate products, and ice cream between sugar preference and non-preference (p < 0.05), whereas no significant differences were found in cake, bread kinds, juice, sweetness milk, yogurt between sugar preference and non-preference (p > 0.05). A significant positive result of intake frequency of sugar food (p < 0.05) was shown for the dietary attitude, BMI, weight, and monthly pocket money. Based on this study, the reduction of sugar intake is needed especially for middle students.

The purpose of this study was to determine the relationship between the students' levels of involvement in school lunch service and their satisfaction levels with the service. A survey was conducted with $5^{th}\;and\;6^{th}$ grade elementary students eating school lunches. Out of 1,680 questionnaires distributed to the students from 14 schools, 1,254 complete questionnaires $(74.6\%)$ were analyzed. The questionnaire included two 5-point multi-item scales for measuring levels of involvement in and satisfaction with school lunch service, respectively. A factor analysis grouped 20 items measuring school lunch satisfaction into three factors: 'food satisfaction', 'nutrition & sanitation satisfaction', and 'service & environment satisfaction'. As a result of multiple regression analyses controlling the influence of such variables as students' grades, gender, school location, years and places of eating school lunches, students' levels of involvement in school lunch service was proven to be positively associated with levels of school lunch satisfaction overall, as well as satisfaction levels in regard to 'food', 'nutrition & sanitation', and 'service & environment', respectively. It was suggested that efforts such as nutrition education to increase students' levels of involvement in school lunches could be a useful strategy to improve students' satisfaction with school lunch service.

Introduction: This research was performed to contract the attitude of dietary restriction and the psychological problems such as depressive mood and perceived stress and to investigate the relationship of these and obesity in women who visited the obesity clinic. Methods: During May 2001, sociodemographic variables, physical characteristics, Three Factor Eating Questionnaire(TFEQ), Symptom Check List-90-R(SCL-90-R) and Perceived Stress Scale were assessed from 150 female who visited the obesity clinics which were located at downtown, Seoul and the Hospital of Ajou University, Medical College. Hamilton depression rating scale(HDRS) was estimated by author. And then 116 female cases who filled up the questionnaire faithfully were included. Results: Obese group more than Body Mass Index(BMI) $25.0kg/m^2$ was 50% of the total subjects. BMI was increased as the age goes up(p<0.001). The frequency of unmarried cases in the under normal weight group was high rate of 48.8% while it in the obese group was 13.8%(p<0.001). There was no significant difference in the rate of smoking and alcohol drinking among subjects by BMI. There was no significant difference of TFEQ among subjects by BMI and the percent of body fat. Factor 2(r=0.27, p<0.01) and Factor 3(r=0.24, p<0.01) were significantly correlated with Global Severity Index(GSI). Only the paranoia scale among each estimated mean value of T scores of SCL-90-R by BMI was the significant difference between the overweight group and the obese group(p<0.05). T scores of scales of SCL-90-R were less than 50, but T scores of the under normal weight group and the obese group were higher than overweight group. GSI was significantly correlated with HDRS(r=0.75, p<0.01) and Perceived Stress Scale(r=0.32, p<0.01). Depressive mood in the obese group was significantly higher than non-obese group that HDRS was compared to two groups by the percent of body fat(p<0.05). Perceived Stress Scale was no significant correlation with BMI and the percent of body fat. All of the subject were in trouble of high stress. Stress affected dietary restriction owing that perceived stress had a relation with Factor 2(r=0.29, p<0.01) and Factor 3(r=0.37, p<0.01). Also, it affected psychological characteristics owing that perceived stress had a relation with the depression scale, GSI and HDRS(r=0.33, r=0.32, r=0.34, p<0.01). Conclusion: Obese women have more psychological difficulties including depression and high perceived stress, which closely related with the attitude of dietary restriction. Psychiatric intervention and aggressive assessment of psychological problems will be needed to the people who visit the obesity clinic in the future.
