Objectives : Despite the increased popularity of highly caffeinated beverages, there is little research examining psychiatric adverse effects. The purpose of this study was to investigate the relationships among pattern of highly caffeinated beverage intake and depressive symptom, suicidal ideation, suicidal plan, suicidal attempt in Korean adolescents. Methods : The data was obtained from the 2014 Korean Youth's Risk Behavior Web-based Study by Korea Centers for Disease Control & Prevention. All participants conducted web-based questionnaire survey. Chisquare test and multiple logistic regression analysis were performed to determine the association among highly caffeinated beverage intake pattern, depressive symptom, suicidal ideation, suicidal plan and suicidal attempt adjusting for differences in age, gender, academic achievement, socioeconomic status. Results : A total of 71,638 participants were enrolled in this study. Depressive symptom, suicidal ideation, suicidal plan and suicidal attempt were significantly more frequent in the group with presence of highly caffeinated beverage intake within 1 week than in non-drinker group(p<0.01). Highly caffeinated beverage intake was significantly associated with suicidal attempt(OR=1.99 ; 95% CI, 1.77-2.22). In addition, depressive symptom, suicidal ideation, suicidal plan and suicidal attempt were significantly more common in the group with heavy-drinker who exceed recommended daily intake dose of caffeine than in the group with light-drinker(p<0.01). Heavy drinking of caffeinated beverage was significantly associated with suicidal attempt(OR=4.05 ; 95% CI, 3.02-5.43). Conclusions : We found that highly caffeinated beverage intake was related to more frequent depressive symptom, suicidal ideation, plan, attempt in adolescents. Also, caffeine intake which exceed recommended daily intake dose identified the predictor of suicidal attempt. Our result suggested that clinicians need to be aware of the possible psychiatric adverse effects of highly caffeinated beverage in vulnerable population including young adolescents.

This study aims to determine the effects of mental health on obesity among Korean adolescents. The data in this study were obtained from the 2013 Korean Youth Health Risk Behavior Web-based Survey conducted in 70,354 adolescents aged twelve to eighteen (35,575 males and 34,779 females) from June 1 to 30, 2013. The variables included age, the economic status of household, academic achievement, health status, perceived happiness, perceived stress, satisfaction of sleeping, perceived depression, and suicidal ideation and the data were processed using t-test, chi square test, and logistic regression analysis. The general characteristics affecting obesity for both Korean male and female adolescents included age (p<0.001), the economic status of households (p<0.001), academic achievement (p<0.001), and health status (p<0.001); the variable of mental health affecting obesity was suicidal ideation among females (p<0.05). It is expected that female adolescents' experience of suicidal ideation can be used as information to predict the likelihood of obesity in managing an obesity program for adolescents and it is necessary to provide obesity education suitable for age and to include obesity guidance in consideration of gender and the economic status.

This study aims to verify mediating effect of ego-resilience and mental health between psychological home environment and adaptation to school of early adolescents in schools with Educational Welfare Priority Project(EWPP). For this purpose, multiple regression analysis and hierarchical regression analysis were conducted on the relationship between psychological home environment and adaptation to school, ego-resilience and metal health of 310 male and female students in fifth and sixth grade in four elementary schools on EWPP located in Busan area. As the result of analysis, three major variables affecting adaptation to school life turned out to be in the order of ego-resilience, home environment and mental health and both ego-resilience and mental health were confirmed to play partial mediating role in the relationship between home environment and adaptation to school life. Since home environment as a psychological variable of adolescents from poor families have an effect on adaptation to school in connection with ego-resilience and mental health as personal variables, this study can be used as base materials for the development of programs to strengthen psychological home environment, ego-resilience, and mental health. In addition, in terms of practical implications, educational welfare policies for alienated class can be practical policy alternative to mitigate social polarization.

It has been argued that internet game overflow (IGO) causes negative effects on mental health among adolescents. Especially, suicide has been known as one of the most serious mental health problems in Korea. This study is to examine the effect of IGO on suicidal ideation among adolescents, and to examine the relationship among IGO, depressive mood, and suicidal ideation by analyzing the mediating effect of depressive mood in the relationship between IGO and suicidal ideation. For this purpose, we analyzed the 2012 dataset from the Korea Children and Youth Mental Health Promotion Study (N=8,745) by the National Youth Policy Institute. The results showed that, first, about 5.6% of adolescents were included in the risky group depending on the criteria of the measurement. Second, IGO has a statistically significant effect on suicide ideation when considering the two variables only. Third, however, as depressive mood was found to have a complete mediating effect in the relationship between IGO and suicidal ideation, IGO increases suicidal ideation by increasing depressive mood. As policy and practice implications, the necessity of intervention to reduce IGO and mental health problems among adolescents was discussed.

Objectives: The objective of this study was to investigate the correlation between insufficient sleep and visuospatial memory in adolescents using a computerized neurocognitive function test. Methods: A total of 103 high school students (26 males and 77 females; mean age $17.11{\pm}8.50years$) without a serious psychiatric problem was recruited. All subjects were requested to complete a self-report questionnaire about weekday total sleep time and weekend total sleep time. The epworth sleepiness scale (ESS) and the beck depression inventory (BDI) were administered to measure daytime sleepiness and symptoms of depression. Seven subsets of the Cambridge Neuropsychological test automated battery were examined to assess visuospatial memory. Results: After controlling for age, sex, ESS, and BDI, longer weekend total sleep time was correlated with poor performance on delayed matching to sample (r = -0.312, p = 0.002) and immediate recall on pattern recognition memory (r = -0.225, p = 0.025). Increased weekend catch-up sleep time was correlated with poor performance of delayed matching to sample (r = -0.236, p = 0.018), immediate recall on pattern recognition memory (r = -0.220, p = 0.029), and delayed recall on pattern recognition memory (r = -0.211, p = 0.036) after controlling for age, sex, ESS, and BDI. Conclusion: This study showed that increased weekend catch-up sleep time reflecting insufficient weekday sleep were associated with poor performance in delayed recall tasks of visual memory. This finding suggests that insufficient sleep during adolescence might produce a decline of visuospatial memory.
