This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (${\geq}\;85$ percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

Objective : The paper aims to provide predictive coefficients via BIA for the assessment of body composition in children and adolescents to serve clinical as well as research purposes. Methods : Body composition via dual-energy x­ray absorptiometry (DXA) and bioelectric impedance as well as other anthropometric index were derived from meaurements on 1026 children and adolescents aged from 6 to 18 years from Beijing City. The best subset regression and principle component analysis were adopted to build the predictive coefficients with the logarithm of body composition via DXA as response variable. Results : Condition index ${\varphi}$ of fat-free mass multiple linear regression achieves 113.49 and 91.18 for males and females respectively, demonstrating severe multicollinearity among anthropometric indexes in children and adolescents. BIA predictive coefficients base on the best subset regression and principle component analysis boast a content predictive value for lean mass ($r^2$ = 0.9697 and 0.9664 for boys and girls respectively, p < 0.0001) and for Fat$\%$ ($r^2$ = 0.7705 and 0.6959 for boys and girls respectively, p < 0.0001). Conclusions : BIA method is applicable for the prediction of body composition for children and adolescents.

This study was conducted to characterize changes in the meal structure of Korean children in terms of temporal and spatial dimensions. The data of 1,891 and 1,627 school-aged children and adolescents extracted respectively from the 1998 and 2009 Korea National Health and Nutrition Examination Surveys were analyzed by gender, age group, and residential area. From 1998 to 2009, the total eating events increased from 4.3 to 4.6 (p = 0.001); the average number of meal intake decreased from 2.8 to 2.7 (p < 0.001) while that of snack intake increased from 1.5 to 1.9 (p < 0.001). The prevalence of "3 meals a day" pattern tended to decrease while that of "2 meals a day" pattern increased over the years. Especially, the "2 meals a day" pattern with "lunch + dinner" increased from 13% in 1998 to 20% in 2009. The percentage of eating breakfast or dinner at home decreased over the years. These results indicate that over the last decade, "destructuration" occurred in Korean children's meal structure in terms of temporal and spatial dimensions. Especially, such alteration was more distinctive in male than female and in the high school-aged group than the elementary or middle school-aged groups. Overall, the difference of meal structure between genders and residential areas became smaller while the difference among age groups became larger over the years.

Objectives: The purpose of this study was to estimate the prevalence of metabolic syndrome (MS), metabolic abnormalities, and nutrient intakes in Korea children and adolescents using the Korea National Health and Nutrition Examination Survey from 2008. Methods: A sample of 838 children and adolescent males (n=442) and females (n=396) aged 10-18 was used from the 2008 Korea National Health and Nutrition Examination survey. The diagnosis of the metabolic syndrome subjects was adapted from modified National Cholesterol Education Program-Adult Treatment Panel III by Ford. To compare nutrient intakes, we used a judgment sampling. The first group was composed of all children and adolescents (n=46) with MS. The second one along with the first group had children and adolescents with the same age, sex, and body mass index (BMI) but without MS (n=46). The control group like the first two had children and adolescents with same sex and same age but with normal BMI and without MS (n=46). Results: In this randomized controlled controlled trial, the prevalence of the metabolic syndrome was 5.8%. The risk factors was associated with the MS were abdominal obesity 9.4%, hypertriglyceridemia 25.0%, low HDL-cholesterol 10.3%, hypertension 23.4%, and hyperglycemia 7.1%. Among metabolic abnormalities, blood pressure was significantly affected by sex, age and obesity. On the other hand, HDL-cholesterol, triglycerides, and waist circumference were directly linked to obesity. There were no significant differences in nutrient intakes among the three groups. Conclusions: The prevalence of MS was higher in children (10-11 years old) than in adolescents (12-18 years old). There was a difference in hypertension among risk factors by gender, and there were no significant differences in nutrient intakes.

This study examined the dietary habits and nutrition quotient (NQ) scores according to leftover food during school meal services among middle school students in the Gyeonggi region. A survey on the dietary habits was conducted among 405 male and female middle school students located in Seongnam City, Gyeonggi Province. The amount of leftover food in the school meals was surveyed using the visual method through a questionnaire over two days. The survey was conducted from July 8, 2019, to July 12, 2019. After calculating the average total leftovers of each student over the two days, they were categorized into the following three groups: the top third was the large leftover group. The middle third was the medium leftover group, and the lower third was the small leftover group. The characteristics of the groups that had leftovers were analyzed. Female, normal-weight, and underweight students accounted for a greater proportion of the large leftover group than male, overweight, and obese students. The rates of selective eating and compliance with new food intake were significantly lower in the large leftover group than in the small leftover group. A comparison of the nutrition quotient for the adolescent (NQ-A) scores of each group revealed significantly lower scores of the large leftover group for all factors (balance, moderation, food diversity, practice, and environment) than the small leftover group. Therefore, there are statistically significant differences in the dietary habits, nutritional quality, and eating behaviors of middle school students that are associated with the amount of leftover food during school meals.

BACKGROUND/OBJECTIVES: Most child and adolescent food literacy measurement tools focus on nutrition and food safety. However, the importance of aspects related to the food system such as food distribution and food waste and their effects on environmental sustainability is growing. We therefore developed and validated a two-dimensional tool for children (8-12 years old) and adolescents (13-18 years old) that can comprehensively measure food literacy. The association of food literacy with diet quality and self-reported health was assessed. SUBJECTS/METHODS: First, we developed a food literacy conceptual framework that contains food system and literacy dimensions through a literature review, focus group interviews, and expert review. After a face validity study, we conducted the main survey (n = 200) to validate the questionnaire. Construct validity and reliability were assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha. RESULTS: As a result of the Delphi study, content validity was confirmed for the remaining 30 items after two items were excluded (content validity ratio = 0.86). Eleven items were excluded from the EFA results, while the CFA results indicated appropriate fit indices for the proposed model (comparative fit index = 0.904, root mean square error of approximation = 0.068). The final food literacy questionnaire consisted of 19 questions and comprised 5 factors: production, distribution, selection, preparation and cooking, and intake. Food literacy was positively associated with diet quality, as assessed by the Nutrition Quotient score, in both children and adolescents and with self-reported health in adolescents.

Objectives: The purpose of this study was to investigate the prevalence of metabolic syndrome and to find related factors according to the number of metabolic syndrome diagnostic components in Korean adolescents. Methods: The subjects of this study were 469 Korean adolescents aged from 12 to 18 enrolled in the 2016 Korea National Health and Nutrition Examination Survey. Statistical package R 3.4.2 was used for programming to apply diagnostic criterion of adolescent metabolic syndrome and for the analysis of the data such as weighted frequent analysis, weighted mean analysis and complex sampling design logistic regression analysis. Results: For adolescents 12 to 18 years of age, 2.55% had more than 2(${\geq_-}3$), 9.88% had more than 1(${\geq_-}2$) and 33.17% had more than 0(${\geq_-}1$) metabolic syndrome diagnostic components. It has been found that risk factors for no less than 2 metabolic syndrome diagnostic components were higher body mass index and higher stress, and risk factors for no less than 1 were higher body mass index, younger teenager and female. Conclusion: Obesity is the primary risk factor for the development of adolescent metabolic syndrome. Female or younger teenager are more likely to have one or more metabolic syndrome diagnostic components, and higher stress develop to the risk level of having two or more metabolic syndrome diagnostic components. Therefore, it is important to focus on obesity and stress management for the prevention and control of Korean adolescent metabolic syndrome.
