Purpose: The purpose of this study was to identify the statistical indicators of OECD and Korea for student health among Korea's approval statistics. Methods: Searching for health indicators by using Health at a Glance 2009, Society at a Glance 2009, and Education at a Glance 2009 through the formal OECD web site in 2010, and investigating the approval statistics through the Korean formal organizational web sites and published data in 2012. Results: Among OECD indicators, indicators for adolescent health were smoking and alcohol consumption, nutrition, physical activity, overweight and obesity, bullying, risk behaviors, and poverty children. However, most of Korea student health indicators were missing except poverty children and life satisfaction, because OECD has taken chiefly data from Health Behavior in School-aged Children survey (HBSC), international study, which has not been carried out in Korea. The Ministry Of Education, Science And Technology (MEST) and the Ministry of Health and Welfare, and National Youth Policy Institute in Korea have produced the major statistics for student health which was only 11 (1.3%) among 858 approval statistics. Conclusion: Identifying a current Korea school health is essential through participating actively to OECD whose statistic indicators are internationally comparable with Students Physical Development Survey, MEST's approval statistics, using Korea Student Health Examination. It was also suggested that quantitative and qualitative expansions for Korea student health statistics by the activation of approval statistics including processed statistics, and by researchers' easy expanded access to a raw data.

Children and adolescents normally have higher Alkaline phosphatase levels than adults. This study was conducted to provide basic data about pediatric reference intervals for ALP. The data from the 2011 Korean National Health and Nutrition Examination Survey was used. Analysis was done for 847 Children and Adolescents (443 boys and 404 girls) aged 10 to 19. The method of p-NPP & EAE buffer was used to get the data. The highest ALP levels were found in boys aged 12 to 13, the reference interval being 653~1,518 IU/L; the levels decreased for those over 13 years old. In the case of girls, the highest ALP levels were found with those aged between 11 and 12, the reference interval being 463~1,598 IU/L; the levels decreased after 12 years of age. The mean difference in all age groups was statistically significant, except for those aged 10 to 11 and 11 to 12. Therefore, it is suggested that pediatric reference intervals should be divided into three groups according to gender. Complementing data about children and adolescents below 10 years old were not included in this study and will be much needed in the next trial.

Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students (n = 310) in the Yongin region of Korea. Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, t- test, and logistic regression analysis. Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; n = 208) and high caffeine intake groups (> 30 mg/d; n = 102). Total nutritional knowledge related to bone disease was higher in the low intake group (score 2.75) than the high intake group (score 2.39; p < 0.05). The high intake group had lower scores for nutritional knowledge (score 0.70; p < 0.05) related to how caffeinated beverages affect sleep and for dietary behavior (score 3.25; p < 0.001), based on "I avoid caffeinated foods before sleep," than the low intake group (nutritional knowledge score, 0.80; dietary behavior score, 3.76). Conclusion: In the overall analysis, the low caffeine intake group had better nutritional knowledge related to bone and sleep health, and healthier dietary behavior related to sleep health compared with the high intake group.

The Committee on Dyslipidemia of Korean Pediatric and Adolescents of the Korean Society of Pediatric Endocrinology has newly developed evidence-based clinical practice guidelines for dyslipidemia in Korean children and adolescents. These guidelines were formulated with the Grading of Recommendations, which include both the strength of recommendations and the quality of evidence. In the absence of sufficient evidence, conclusions were based on expert opinion. These guidelines are based on the 2011 National Heart, Lung, and Blood Institute Guidelines, which focus on the prevention of cardiovascular disease in children and draw from a comprehensive review of evidence. These guidelines contain the definition of and screening process for dyslipidemia and introduce new dietary methods: the Cardiovascular Health Integrated Lifestyle Diet (CHILD)-1, the CHILD-2-low-density lipoprotein cholesterol, and the CHILD-2-triglyceride. Potential drug therapies for dyslipidemia along with their main effects and doses were also included.

This study was conducted to investigate the effect of administration of calcium supplementary food containing fermented product of Bacillus subtilis SE4 highly producing poly-$\gamma$-glutamic acid on the growthparameters of adolescent male rats. Four-week old male Sprague-Dawley (SD) rats were fed for 4 weeks and assigned to the following 4 groups: two groups administered orally with new calcium supplementary food (such as 150 mg/kg and 300 mg/kg) containing fermented product of B. subtilis SE4, one group administered with conventional calcium supplementary food product (150 mg/kg) and one saline group as control. Daily weight gain and daily food intake in the two new food product groups were higher than those of conventional food product group and control group. Especially, the content of serum IGF-I in the two new food product groups were significantly higher than those in conventional food product group and in control group (p<0.05). In addition, length and weight of longitudinal bone in the two new food product groups were longer and heavier than those of conventional food product group and control group. Therefore, the addition of fermented food product of B. subtilis SE4 into the conventional calcium supplementary food increased all the parameters examined for the growth of the adolescent male rats.

Purpose: This study sought to predict the reasons for skipping breakfast by adolescents aged 13-18 years using the 7^th Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The participants included 1,024 adolescents. The data were analyzed using a complex-sample t-test, the Rao Scott χ²-test, and the classification and regression tree (CART) algorithm for decision tree analysis with SPSS v. 27.0. The participants were divided into two groups, one regularly eating breakfast and the other skipping it. Results: A total of 579 and 445 study participants were found to be breakfast consumers and breakfast skippers respectively. Breakfast consumers were significantly younger than those who skipped breakfast. In addition, breakfast consumers had a significantly higher frequency of eating dinner, had been taught about nutrition, and had a lower frequency of eating out. The breakfast skippers did so to lose weight. Children who skipped breakfast consumed less energy, carbohydrates, proteins, fats, fiber, cholesterol, vitamin C, vitamin A, calcium, vitamin B1, vitamin B2, phosphorus, sodium, iron, potassium, and niacin than those who consumed breakfast. The best predictor of skipping breakfast was identifying adolescents who sought to control their weight by not eating meals. Other participants who had low and middle-low household incomes, ate dinner 3-4 times a week, were more than 14.5 years old, and ate out once a day showed a higher frequency of skipping breakfast. Conclusion: Based on these results, nutrition education targeted at losing weight correctly and emphasizing the importance of breakfast, especially for adolescents, is required. Moreover, nutrition educators should consider designing and implementing specific action plans to encourage adolescents to improve their breakfast-eating practices by also eating dinner regularly and reducing eating out.

Purpose: This study aimed to investigate the changes in health behavior, mental health, and nutritional status of Korean adolescents before and after the coronavirus disease 2019 (COVID-19) pandemic outbreak. Methods: A total of 800 adolescents (12~18 years old) who participated in the 2019-2020 Korea National Health and Nutrition Examination Survey (KNHANES) were included as study subjects and divided into four groups (204 middle school boys, 172 middle school girls, 219 high school boys, and 205 high school girls). The 2019 and 2020 KNHANES data were classified into data collected before and after the COVID-19 outbreak, respectively. Results: After the COVID-19 pandemic outbreak, middle school boys showed an increased tendency toward becoming overweight and obese, with significantly increased levels of diastolic blood pressure and insulin. While there was no major change in the subjective health status among adolescents, the high school boys showed a significantly decreased physical activity after COVID-19 outbreak. Moreover, the proportion of middle school students feeling a little stressed significantly increased after the COVID-19 outbreak. The rate of skipping breakfast significantly increased in middle school girls, but the rate of having lunch with companions significantly increased among all adolescents after the COVID-19 outbreak. However, the intake of milk, vegetables, fruits, seaweeds, and pulses significantly decreased, although the intake of sugars, beverages, and seasonings significantly decreased as well, during this period. These changes may lead to an increased proportion of adolescents with insufficient intake of nutrients, including potassium, vitamin C, and riboflavin. Conclusion: These results highlight the impact of COVID-19 on comprehensive changes in physical and mental health status, lifestyle behavior, and nutritional status in adolescents, suggesting the need for targeted prevention and intervention for physical and mental well-being during the pandemic.

Purpose: The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. Methods: Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017-2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. Results: The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B₁, niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents' physical activity increased. Conclusion: The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.

The purpose of this study was to evaluate vegetable intakes according to body mass index (BMI) of adolescents. For this, 400 middle and high school adolescents living in Buyeogun, Chungnam were classified into underweight group, healthy weight group, and overweight group according to BMI, after which eating habits, daily intake levels of vegetables, perception of vegetables, and vegetable-related eating habits were compared and analyzed. As the reason for skipping breakfast, 'Lack of time (44.3%)' was the most frequently cited. In the case of unbalanced food intakes, the underweight group and overweight group showed the highest response for 'grain' while the healthy weight group showed the highest response for 'vegetables' with significant differences (P<0.001). Daily intakes of one serving size of vegetables was 3.3 in the underweight group, 3.8 servings in the healthy weight group, and 3.8 servings in the overweight group, but there was no significant difference. However, frequency of vegetable intake at lunch was once in the underweight group, which was significantly lower than 1.3 servings in the healthy weight group and 1.4 servings in the overweight group (P<0.05). Regarding perception of vegetables, perception of 'Vegetable consumption helps to get beautiful skin' (P<0.01) and 'I eat vegetables or don't eat depending on a cooking method' (P<0.05) were significantly higher in the underweight group. In the evaluation of vegetables-related eating habits, preference for vegetables in the underweight group was lower than that in the healthy weight and overweight groups (P<0.05). Summarizing the above results, vegetable intake by adolescents was generally low, and the frequency of vegetable intake at lunch as well as preference for vegetables were significantly lower in the underweight group. Studies to identify the relationships between adolescent body types and vegetable intakes are required.
