BACKGROUND/OBJECTIVES: This study aimed at evaluating the dietary intakes of Korean adolescents affected by food insecurity, in comparison with those who were food secure. SUBJECTS/METHODS: The study used one day 24-hour dietary recall data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. The study subjects consisted of 1,453 adolescents of whom 695 were middle school-aged and 758 were high school-aged. Food security status was assessed using the 18-item questionnaire. Nutrient intake was evaluated in terms of nutrient density, insufficient intake, and excessive intake for selected nutrients, in addition to meeting the appropriate range for total energy intake and energy intakes from carbohydrate, sugar, protein, fat, and saturated fatty acids. Food intake was evaluated in terms of food group servings and dietary diversity score (DDS). RESULTS: The percentages of food insecurity were 11.1% for middle school-aged adolescents and 16.8% for high school-aged adolescents. Food insecure middle school-aged adolescents had higher intake of carbohydrate (P = 0.006) but lower intake of fat (P = 0.010) and saturated fatty acids (P = 0.005) than their food secure counterparts although the intake of both groups was in the recommended ranges. Nutrient intake among high school-aged adolescents was generally similar regardless of food security status. Both food secure and insecure adolescents showed insufficient intake of vitamin A, vitamin C, and calcium, and excessive sodium intake. They additionally had low prevalence of meeting appropriate intake ranges for energy, carbohydrate, and sugar. Food intake in terms of food group servings and DDS was also similar regardless of food security status among both age groups, with low intakes of foods from fruit and dairy groups. CONCLUSIONS: Except for a few nutrients among the middle school-aged adolescents, dietary intakes among Korean adolescents did not differ by food security status in this study.

Purpose : Health Risk behaviors are a leading cause of preventable morbidity and mortality. Adolescents is a critical transitional period for establishing health behavior for healthy life. The purpose of this study was to describe the types and frequency of the health risk behaviors being performed by middle school students, examine the gender and grade differences of health risk behaviors, and identify the relationship among health risk behaviors. Methods : A total of 1952 early adolescents recruited from 7 middle schools in a district of urban setting completed questionnaires. Youth Risk Behavior Survey-Middle school questionnaires was used to identify the types of health risk behaviors among early adolescents. Data were analyzed by descriptive statistics and Chi-Square test using SAS program . Results : The results showed the frequency for most health risk behaviors and increased with advancing grade level. Males were more likely than females to behaviors related to smoking and violence, whereas females were more likely than males to have suicidal thoughts, be physical inactive and attempt to lose weight. Among health risk behaviors, the relationship of alcohol experience, smoking, and suicide was high. Conclusion : The findings identify a high risk target group among middle school adolescents and suggest that preventive intervention strategies should take into consideration the types with gender and grade, and provided the evidence that one of health risk behaviors may induce the other health risk behaviors.

Objective: The purpose of this study was to examine the mediating role of school adjustment in the relationship between adolescents' mastery goal orientation and life satisfaction, and the differences according to gender in the relationship. Methods: The participants were 1,947 students from the 3rd, 4th, and 5th waves of the Korean Child Youth Panel Study(KCYPS). The data were analyzed with structural equation modeling(SEM) and multiple group analysis. Results: First, school adjustment of 1st graders in middle school mediated the relation between mastery goal orientation of 6th graders in elementary school and life satisfaction of 2nd graders in middle school. Second, the differences in gender were confirmed. The effect of mastery goal orientation of 6th graders in elementary school on school adjustment of 1st graders in middle school is higher for boys. In contrast, the effect of school adjustment of 1st graders in middle school on life satisfaction of 2nd graders in middle school is higher for girls. Conclusion/Implications: The results of this study suggested that mastery goal orientation before entering middle school and school adjustment after entering middle school could be important variables to increase adolescents' life satisfaction. Also, it is necessary to consider gender difference for long-term intervention for improving adolescent life satisfaction.

Purpose: This study was aimed to identify factors related with depression among boys and girls in Korean middle school adolescents. Methods: This study used the data from the 2007 annual survey of youth health behaviors conducted by the Korea Centers for Disease Control and Prevention between the period of 2007/9/1 and 2007/9/22 (with the extension of 2007/10/1 and 2007/11/3). The target number of this study was 21,047 male and 18,424 female students all in the age group of middle school 1st grade and 3rd grade. Results: Depression of middle school adolescents was 33.4% for male students, 43.8% for female students, 38.3% in overall. With regard to the relationship between the demographic characteristics and the health behavior, both male and female students felt more depressed when they had more stress, followed by the cases with stimulant intakes and chronic diseases. For male students, higher level of physical activity was associated with greater level of the depression. For female students, living with only one parent or other person seem to cause more depression. Conclusion: Depression of middle school adolescents requires a special attention from the family, the school and society in general to find out and eliminate the root of these symptoms.
