This study tests the path model which examines how the variables of past and present family dynamics, school adjustment, filed life events affect the adolescents'depression which in tum influencing their suicidal ideation. In the path model, the exogenous varialbes were negative parenting experience in childhood, maladjustment history of the family (e.g., alcohol, divorce), present parent-adolesecent communication, school adjustment, filed life events were used, whereas the adolescent depression was used as the mediated variable. The endogenous variable was the adolescent suicidal ideation. The respondents of the survey were 635 adolescent who were 1st and 2nd grade of high school located in Seoul and Busan. Using SPSS for Windows, the path analysis was done for male and female adolescents separately, since female adolescents were found to report significantly higher degree of depression and suicidal ideation then were male adolescents. The results of the path analysis were as followings. First, for both the male and female adolescents, depression was the strongest predictor of their suicidal ideation. Also, school adjustment strongly affected the adolescents'depression as well as their suicidal ideation. Meanwhile, filed life events indirectly influenced the suicidal ideation only through the depression. Second, for the male adolescents, negative parenting experience in childhood affected both the depression and suicidal ideation, while the parent-adolescent communication directly affected the suicidal ideation. Third, for the female adolescents, maladjustment family history and negative parenting experience did not affect their depression, but the suicidal ideation. Meanwhile, parent-adolescent communication was a significant predictor of female adolescents'suicidal ideation as well as their depression. In conclusion, discussion on different path of male and female adolescents'suicidal ideation was provided.

Purpose: The purpose of this study was to determine the relationship between unhealthy eating behavior and depression in adolescents, with confounding variables adjusted. Methods: This study is a secondary analysis of the data collected from the 2013 Korean Youth Risk Behavior Web-based Survey (KYRBWS). The analysis included 72,435 participants (36,655 male and 35,780 female). The data were analyzed by $x^2$ test, t-test, and logistic regression analysis using SPSS Version 21 by complex samples analysis. Results: Compared with male adolescents with healthy eating behavior, those who with unhealthy eating behavior were more likely to suffer depression with other factors controlled (OR=1.37, 1.07~1.75). On the other hand, female adolescents with unhealthy eating behavior were less likely to feel depressed compared with female adolescents with unhealthy eating behavior and with other factors controlled (OR=0.98, 0.64~1.50). However, it was not statistically significant. Conclusion: Our findings suggest that healthy eating behavior may be a protective factor against depression in male adolescents, but not in female adolescents. Furthermore, our results suggest that the longitudinal associations between mental health and healthy eating behavior and other lifestyle factors are complex.

Background: Smoking exposure may be objectively assessed through specific biomarkers. The most common biomarker for smoking is cotinine concentration in urine, and setting an optimal cut-off point can accurately classify smoking status. Such a cut-off point for Korean adolescents has never been studied. Objectives: The aim of this study was to determine a cut-off point for urinary cotinine concentration for the discrimination of smoking in adolescents. Methods: Participants were adolescents aged 13~18 years who participated in the third cycle of the Korean National Environmental Health Survey. We used urine samples to confirm the level of cotinine concentrations. Smoking status was determined by self-reported questionnaire. We identified the optimal cotinine cut-off point for discriminating smoking status using receiver operating characteristic curve analysis. Results: Of the 904 participants, 28 (3.1%) were smokers, among whom 20 (71.4%) were male. The median urinary cotinine concentrations in smokers was 218 ㎍/L (male: 215 ㎍/L, female: 303 ㎍/L), and that in non-smokers was 1.31 ㎍/L (male: 1.46 ㎍/L, female: 1.18 ㎍/L). We found significant differences in urinary cotinine concentration according to smoking status and sex (p<0.001). Urinary cotinine concentrations performed well for identifying smoking adolescents [area under the curve: 0.954 (male: 0.963, female: 0.908)]. The cut-off that optimally distinguished smokers from non-smokers was 39.85 ㎍/L (sensitivity: 89.3%, specificity: 97.4%). Male [39.85 ㎍/L (sensitivity: 90.0%, specificity: 94.9%)] had a different optimal cut-off point than female [26.26 ㎍/L (sensitivity: 87.5%, specificity: 99.6%)]. Conclusions: This study determined a cut-off point for urinary cotinine of 39.85 ㎍/L (male: 39.85 ㎍/L, female: 26.26 ㎍/L) to distinguish smokers from non-smokers in adolescents.

Objectives: The purpose of this study was to investigate the relationship between stress levels and eating habits in adolescents. Methods: A total of 453 male and female high school students were surveyed to ascertain their stress levels, Nutrition Quotients for Korean Adolescents (NQ-A), and stress-related eating behavior. Results: The average age of the subjects was 18 and they were mostly from nuclear families. Their average daily conversation time with their parents was between 10 to 30 minutes. The average sleep time for female students was observed to be less than that of male students. The satisfaction level of academic achievement of female students was significantly lower than that of the male students (P < 0.001). The average stress level score for female students was 2.7 out of 5, which was significantly higher than the male student's score of 2.4 (P < 0.001). The eating speed of male students was related to stress levels. Both male and female students ate more and craved spicy food when under stress. All male and female students had significantly ascending NQ-A scores rising in the order of stress from 'low level' to 'medium level', to 'high level' (P < 0.001). There was a significant negative correlation between the stress score and the NQ-A score adjusted for general characteristics (r = -0.29, P < 0.001). Conclusions: Since stress and NQ-A were negatively correlated in high school students, higher stress levels can be associated with irregular eating habits and negative eating behavior. Therefore, stress management and nutrition education focusing on stress status are needed for adolescents.

This study was conducted to investigate the eating habits, self-perception of body image, and weight control behavior in Korean adolescents by gender. Data pertaining to 70,809 subjects(male 37,090, female 33,719) were obtained from the sixth Korea Youth Risk Behavior Web-based Survey(2010). The rate of skipping breakfast was 42.5% in male, and 45.8% in female students. The intake frequency of vegetable, milk, soda, fast food, and instant noddles was higher in male than female students. Moreover, 33% of male and 31.9% of female students considered themselves to be somewhat or very obese. Notably, 2.3% of underweight students considered themselves to be obese. Weight control measures were practiced in 44.6% of male, and 54.6% of female students. Meal restrictions were used more frequently to control weight by females, while exercise was used more by males. The perceived stress level was higher in female than male students, especially that due to appearance. Therefore, integrated and personalized high school nutrition programs according to gender should be implemented to establish proper body image perception and eating habits, as well as to develop selfesteem.

Background: Anemia is an important health problem affecting approximately 25% of the global population. Although its prevalence is decreasing worldwide, few studies have examined the prevalence of anemia in Korean adolescents. Purpose: This study aimed to determine the prevalence of anemia in Korean adolescents over the past 21 years using data from the Korea National Health and Nutrition Examination Survey. Methods: We investigated the prevalence of anemia in adolescents aged 10-18 years for the period 1998-2018 according to sex, age, residential area, and household income. The effects of menarche age and menstruation were examined in female adolescents for the period 2001-2018. Results: Among the total 11,782 participants, the weighted prevalence of anemia was 4.0%. The prevalence of anemia in male participants significantly decreased (from 3.0% to 0.5%, P<0.001), whereas that in female participants did not change significantly over time (from 7.9% to 8.5%, P=0.054). The average age at menarche was 12.4±0.0 years; the prevalence of anemia in females increased from age 13 years onward. Multivariate analysis revealed that anemia was more common in female than male participants (odds ratio [OR], 9.88; 95% confidence interval [CI], 7.19-13.57; P<0.001). In female adolescents, the prevalence of anemia increased with age (OR, 1.26; 95% CI, 1.15-1.38, P<0.001) and was 3.6 times higher after than before menarche (OR, 3.65; 95% CI, 2.21-6.05, P<0.001). Conclusion: Over the 21-year study period, the prevalence of anemia decreased among male adolescents but did not change in female adolescents. In female adolescents, age and menarche were identified as significant risk factors that require continued attention.

The purpose of this study was to investigate about the effects of parental rearing behavior on self-esteem and gender role stereotype during adolescence and to reveal the mediating effect of self-esteem on adolescents' gender role strerotype. Also investigated the relationship among these variables and condition variables. For this purpose, used the Second Grade longitudianl Panel data of Middle School from the Korea Youth Panel Survay(KYPS). And the latent growth model was analyzed 3,449 men and women adolescents' cases of the first, the fourth and the sixth wave of the Korea Youth Panel Survey(KYPS) administered by Korea Institute for Youth development. And the structural equation model was used to investigate whether self-esteem mediates parental rearing behavior and male and female gender role Strerotype. The results of this study, the direct effect between variable factors showed that the more positive the parenting behavior of the second grader of middle school is, the more positive the self-esteem of male adolescents and the initial value of stereotypes of male gender role. It also affects the self-esteem of female adolescents and stereotypes of female gender roles but not statistically significant. The male gender role stereotypes were decreased in influence by the rate of change of parental rearing behaviors, and the initial value and the rate of change of self-esteem were statistically influenced to the male gender role stereotypes and the higher the self-esteem, the higher the self-esteem. However, there was no significant effect on stereotypes of female gender roles. As a result of analyzing the mediating effect of self-esteem, partially mediated between the initial value of parental rearing behavior and initial stereotype of male gender role, but there was no longitudinal mediation effect. There was no mediating effect of self-esteem between parental rearing behaviors and stereotypes of female gender roles and there was no longitudinal mediation effect. The effect of condition variable gender was found that female adolescents are more affected by paretal rearing behavior than male adolescents and also affected by the growth process. The monthly income of households influenced the initial value of parental rearing behaviors and showed a difference in parental rearing behavior according to household income. And the higher the mother 's educational level, the more the self-esteem of male adolescents was affected.

The variables studied in relation to adolescents' prosocial behaviors were grade, prosocial moral reasoning, empathy, self-esteem, parental prosocial behaviors, support and marital conflict, social economic status, peer prosocial behaviors and support, teacher support, school life satisfaction and achievement. The sample consisted of 837 seventh and tenth grade adolescents. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, t-test, Pearson's correlation and multiple regression. Several major results were found from the analysis. First, female students had more prosocial behaviors than male students. Second, male and female students' prosocial behaviors showed positive correlations with grade, prosocial moral reasoning, empathy, self-esteem, parental and peer prosocial behaviors and support, teacher support and school life satisfaction. However, female students' prosocial behaviors had a negative correlation with parental marital conflict. Third, important variables predicting male and female students' prosocial behaviors were empathy, peer prosocial behaviors and parental prosocial behaviors. Important variables predicting male students' prosocial behaviors were teacher support and prosocial moral reasoning. On the other hand, the important variable predicting female students' prosocial behaviors was self-esteem.
