Objectives: Following the coronavirus disease 2019 (COVID-19) pandemic, adolescents have experienced decreased physical activity and a decline in mental health. This study analyzed the association between changes in depressed mood after the COVID-19 pandemic and physical activity among adolescents. Methods: The analysis was based on the results of the 17th Youth Health Behavior Online Survey conducted in 2021, which included 54848 middle and high school students in South Korea. Information on physical activity included low-intensity physical activity lasting >60 min/day, high-intensity physical activity, and strength training exercises. A logistic regression analysis was performed to evaluate the association between physical activity and changes in depression after the COVID-19 pandemic. Results: After adjusting for sociodemographic characteristics and previous depression, adolescents who performed strength training exercises more than once per week had a 0.95-fold lower risk (odds ratio [OR]=0.948, 95% confidence interval [CI]=0.905-0.994, p=0.027) of increasing depression after the COVID-19 pandemic, while the risk of decreasing depression increased by 1.22-fold (OR=1.215, 95% CI=1.131-1.305, p<0.001). The results were not significant for low-intensity physical activity for >60 min/day and high-intensity physical activity. Conclusion: Strength-training exercises are significantly associated with the prevention of depression among adolescents following the COVID-19 pandemic.

Objectives The relationship between depression, obesity, life style of adolescents has been reported, but the results were not consistent. Thus this study was designed to find out the relationship. Methods The participants were the first and second grade middle school students. The participants were asked to measure their height and weight etc, and were asked to survey questionnaires. To diagnose the students' degree of depression, Children's Depression Inventory(CDI) by Kovas and Beck. Results The average depression score in the obese group was significantly higher than that of the normal body weight group. In addition, male obese group scored higher on CDI than the female obese group, and the obese group of participants who don't exercise, but like to play computer games and watch TV scored higher on CDI than the group who exercise and don't play computer games. Conclusions This study proved that depression in adolescent was closely related with obesity and obesity-related lifestyles. "The research was supported by the Kyung Hee University Research Fund in 2007"(KHU-20071638).

Objective : The purpose of this study was to examine the relationship between self-reported sleep duration and depression or suicidal ideation in Korean adolescents. Methods : The data obtained from the 11th Korea Youth Risk Behavior Web-Based Survey (KYRBWS) were analysed. 68,043 students from 797 schools participated in this nationwide survey. Results : 53.7% of male students and 68.4% of female students had reported that a weekday sleeping duration of less than 6 hours. When the depression and suicidal ideation were analyzed by age, the odds ratio was higher in middle-school students than in high-school students. Both male and female students showed a higher risk of depression and suicidal ideation when sleeping duration was less than 5 hours and the risk was slightly higher in boys than in girls. Conclusion : Insufficient sleep duration in Korean adolescents increases depression and suicidal ideation, and these results differ according to age and gender.

Objectives: We examined the factor structure of the Adolescent version of the General Behavior Inventory (A-GBI) for Koreans. Methods: We retrospectively reviewed the medical records of 220 adolescents (age, 12-18 years) who completed the A-GBI through the Department of Psychiatry at Asan Medical Center, Seoul, Korea, from October 2011 to December 2018. Caregivers of the study participants completed the Parent version of the GBI (P-GBI) 10-item Mania Scale. The adolescents were evaluated based on the A-GBI, Children's Depression Inventory (CDI), and Revised-Children's Manifest Anxiety Scale (RCMAS). Subsequently, an exploratory factor analysis (EFA) using the maximum likelihood method with direct oblimin rotation and correlation analyses with other scales were performed. Results: The EFA identified a two-factor structure as having the best fit: factor I included depressive symptoms and factor II included hypomanic/biphasic symptoms. Factor I was very strongly correlated with the A-GBI depressive subscale (r=0.990, p<0.001) and strongly correlated with CDI (r=0.764, p<0.001) and RCMAS (r=0.666, p<0.001). Factor II was also very strongly correlated with the A-GBI hypomanic/biphasic subscale (r=0.877, p<0.001) and weakly correlated with CDI (r=0.274, p<0.001) and RCMAS (r=0.332, p<0.001). Conclusion: The above findings support a two-dimensional model of mood symptoms in Korean youth.

Objectives : This study examined the impact of peer's suicide on mental health of middle-school students. The aim of this study was to describe the course of posttraumatic stress and grief reaction, suicide ideation, and depression score among adolescents after exposure to peer's suicide and to examine the relationship between posttraumatic stress and other mental health scores in these subjects. Methods : Thirty seven middle school students who were exposed to the suicidal death of a peer completed self-report measures to assess levels of depression, grief reaction, post-traumatic stress, and suicide ideation at 1 month and 8 months after the peer's suicide. Results : There was no significant change in mental health scores between 1 month and 8 months. Level of posttraumatic stress after 8 months was related to acute grief response. Subjects who experienced a clinically significant level of suicidal ideation and posttraumatic stress showed more mental health problems. Conclusion : The results suggested that peer's suicide strongly impacted mental health issues of adolescents at a critical time of adolescent development. Clinicians should perform a thorough evaluation of mental health problems for youth who experienced peer's suicide and help them in management of their grief reaction.

Purpose: The purposes of this study were 1) to compare the contribution of demographic-behavioral variables and psychological variables in explaining the variance of depression, 2) identify the most important predictors of depression for Korean female adolescents. Method: The participants were 840 female adolescents. Data was collected through self-report questionnaires, which were constructed to include demographic-behavioral factors, self-esteem, hostility, hopelessness, and depression. Data was analyzed using the SPSS program. Result: Female adolescents' demographic-behavioral variables explained 17% of the variance in depression, and perceived physical health status, history of physical abuse, smoking, satisfaction of body weight, parental alcohol abuse, parental divorce, and history of suicidal attempt were the significant predictors of depression for female adolescents. Psychological variables explained 50% of the variance in depression, and self-esteem, hostility, and hopelessness were the significant predictors of depression for female adolescents. The significant predictors of depression among female adolescents' demographic-behavioral variables and psychological variables were self-esteem, hostility, hopelessness, perceived physical health status, parental alcohol problem, and history of physical abuse, explaining 52% of the variance in depression. Conclusion: In order to reduce depression in female adolescents, it is necessary to design an intervention program that emphasizes improving self-esteem while reducing hostility and hopelessness.

The present investigation of the relations among economic hardship, parental child-rearing attitudes and adjustment in adolescence was carried out with 528 middle school children and their mothers in Kyung-gi province. Questionnaires for mothers were on economic stress, and children's questionnaires were on perceived parental attitudes as well as their own adjustment behaviors, such as aggression, depression, and negative self-concept. Adolescent boys perceived paternal child-rearing attitudes more rejecting and inconsistent when the family experienced income loss. Paternal nurturing behaviors perceived by children were also reduced under poor paternal working conditions. Change in family life style due to economic hardship resulted in higher adolescent depression.

Purpose: The purpose of this study was to examine the relationship between sleep duration, quality of sleep and depression, and to identify the factors associated with depression in middle school students. Methods: This study used a cross-sectional design with secondary data, middle school student panel data from the Korean Children and Youth Panel Survey (2018), and data from a total of 2,590 students was used for analysis. For the statistical analysis, t-test, ANOVA, and hierarchical multiple regression were performed using SPSS ver. 26. Results: The mean depression score in adolescents was 17.99±6.38. Depression had significant differences according to sleep duration and quality. Adolescents with less than eight hours of sleep showed the highest depression, and poor sleepers showed higher depression scores than good sleepers. Gender, school achievement, school satisfaction, economic status, and exercise time were found to significantly relate to depression. After controlling for general characteristics, depression explained 17.2% of the variance in quality of sleep (β=-.15, p<.001) and sleep duration (β=-.04, p=.022). Conclusion: These findings indicate that it is necessary to develop intervention strategies to enhance the quality of sleep and appropriate sleep duration for preventing depression in adolescents.

Recently, rates of depression and suicide of adolescents in industrialized countries, including Korea, were rapidly increasing. Adolescent depression was often associated with anxiety disorder, eating disorder, attention deficits hyperactivity/disruptive behavior disorder. and suicidal attempts. Epidemiological data about depression and suicide of adolescents are reviewed. Psychological theories of depression and suicide are integrated in terms of a control theory interpretation. Issues about 'relationships between depression and anxiety' 'relationships between depression and suicide' 'the reason why rates of depression and suicide are rapidly increasing at adolescence' 'the reason why the different prevalence of depression between female and male is conspicuous at adolescence' and 'Korean culture associated with depression and suicide of adolescents' are discussed in terms of the revised control theory interpretation.
