Objectives : The objective of this study was to identify the risky behavior subtypes in adolescents with depression, and the relationship between those subtypes and suicide attempt. Methods : Ninety adolescents who met the Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria for major depressive disorder, dysthymia, or depressive disorder not otherwise specified participated in the study. Participants were interviewed about suicidal attempts, non-suicidal self-injuries. Smoking, drinking behaviors, and searching for the word "suicide" on the internet, negative life events including bulling-bullied experiences, and history of abuse were also included with questionnaires. Results : The results of cluster analysis showed that four risky behaviors were divided into three clusters : non-risky type, characterized by few risky behaviors ; delinquency type, which was characterized by smoking and drinking ; non-suicidal self-injury type. In non-suicidal self-injury type, percentage of girls was higher and clinical symptoms were more severe than delinquency type. In addition, delinquency type members could be a bully, while non-suicidal self-injury type members could be abused by a family member. Logistic regression analysis showed that both risky behavior subtypes were significant predictors of suicide attempt. Conclusion : These results suggest that two types of risky behaviors of depressed adolescents have an effect on the suicide attempts independently. Then, the implications and limitations of the study were discussed and directions for future studies were suggested.

Objectives: This study was conducted to measure the intake rate of SSBs (sugar sweetened beverages) and examine the relationship between health behavior factors and SSBs intake by adolescents. Methods: This study used data from the 2016 Korea Youth Risk Behavior Web-based Survey, which included 65,528 study participants. SSBs intake frequency was measured by asking respondents if they consumed soda, high-caffeinated beverages, and sugary drinks during the previous week. Type of intake was categorized into three groups according to the number of consumed drinks [SSBs (0): None; SSBs (1-2): 1 or 2 consumed; SSBs (3): 3 consumed]. Multinomial logistic regression analysis was used to examine health behaviors that affected SSBs consumption. Results: Increased SSBs intake was significantly correlated with current smoking (OR=2.4, 95% CI=1.82-3.17), current drinking (OR=2.13, 95% CI=1.82-2.51), sedentary time increase (OR=1.31, 95% CI=1.15-1.49), three days or more physical activity per week (OR=1.12, 95% CI=1.02-1.24), <8 hours sleep (OR=1.6, 95% CI=1.43-1.78), increased internet usage time (OR=1.44, 95% CI=1.25-1.65). Conclusions: Sugar-sweetened beverages intake by Korean adolescents was associated with health behaviors such as smoking, drinking, sedentary time increase, more physical activity, poor sleeping time, and increased internet use time. Based on these results, it is necessary to recognize the influence of SSBs intake and to intervene to reduce consumption of SSBs.

Purpose: The purpose of the study was to investigate health behavior changes in Korean adolescents before and during the COVID-19 pandemic. Methods: A descriptive cross-sectional design was employed. Data were obtained from the 15~16th (2019~2020) Korea Youth Risk Behavior Web-based Survey. Overall, the data of 112,251 students, 57,303 before the COVID pandemic and 54,948 during the pandemic, were included. The data were analyzed using rao-scott 𝝌²-test, t-test, ANCOVA and logistic regression analysis. Results: While sitting time for study decreased, sitting time for leisure increased in the 2020 group compared to the 2019 group. The 2020 group was more likely to skip breakfast and have a higher BMI than the 2019 group. The 2020 group was less likely to consume fruit and engage in moderate and vigorous physical activities than the 2019 group. The 2020 group was less likely to engage in CC, EC, and HTP current smoking and be exposed to secondhand smoke at home, school, and public places than the 2019 group. The 2020 group was more likely to be satisfied with sleep, but less likely to experience stress, depression, suicidal ideation, suicidal plans, and suicidal attempts than the 2019 group. Conclusion: It is necessary to reduce sedentary time, encourage physical activities, manage smoking and drinking rates continuously, and establish a network system to prevent psychological loneliness and isolation for adolescents, which requires participation of experts from the community as a whole.

The purpose of this study was to examine the relationship between the smoking and eating habits of high school students. We also presented the basic data for the effective smoking cessation and smoking prevention programs, and proper nutrition education programs. We surveyed 304 high school male students in Sokcho city. The results were as follows ; a total of 23.7% of the subjects were smokers, the smokers spent more pocket money than the non-smokers and they also spent more time on the internet or smartphone. The smokers had lower awareness of the dangers of smoking than that of non-smokers. They started drinking alcohol earlier than the non-smokers. Their water intake was higher and they preferred consumption of high-protein foods like fried chicken, but were not inclined to vegetables and sour tasting foods. These results imply that smoking habits of the subjects affected their eating and drinking habits. A matter of concern was the low intake of vegetables and sour tasting foods, which could lead to a deficiency of nutrients such as vitamins, minerals and dietary fibers. The smokers were less satisfied with their school life than the non-smokers. There was a negative correlation with the degree of awareness of the dangers that smoking can cause. Conversely, the amount of smoking and drinking habits were positively correlated. To reach a healthy adulthood, it is crucial to quit smoking and participate in smoking prevention education along with nutrition education and abstinence education for the adolescents.

Purpose: The aim of this study was to identify the effects of community mapping based on volunteered Geographic Information System on smoking prevention among female middle school students. Methods: This study used a triangulation method which integrated quantitative data from a "pre-post" study on a nonequivalent control group and qualitative data from focus group interviews. Data was collected from 4 August 2015 to 10 January 2016. The experimental group (n=24) participated in community mapping along with education on smoking prevention and the control group (n=28) participated only in routine education. Both groups were measured on their knowledge and attitude related to smoking prevention through self-report questionnaires. The quantitative data was analyzed by descriptive statistics, $x^2$ analysis, and t-test using SPSS 23.0. The qualitative data was collected through focus group interviews to investigate the social-environmental effect of smoking prevention. Results: Knowledge related to smoking prevention was significantly higher (t=2.591, p=.013) in the experimental group than the control group. But attitude related to smoking prevention did not show significant differences between the two groups. When asked about their experiences of the community mapping program, it turned out to be a process where they could learn practical knowledge related to smoking prevention and experience their individual practices manifested as collective intelligence while working together with community members. The study found that community mapping had an effect on smoking prevention from a social and environmental aspect. Conclusion: To be more effective, school education on smoking prevention should be provided in connection with the community. It is also desirable to provide an opportunity where adolescents can experience discovering and solving practical problems along with their own community.

Objective: The possibility that smoking prevalence among junior and senior high school students may decrease with increasing mobile phone bill was reported by the mass media in Japan. We conducted a nationwide survey on adolescent smoking and mobile phone use in Japan in order to assess the hypothesis that mobile phone use has replaced smoking. Methods: A total of 70 junior high schools (response rate; 71%), and 69 high schools (90%) from all over Japan responded to 2005 survey. Students in the responding schools were asked to fill out an anonymous questionnaire about smoking behavior, mobile phone bill, and pocket money. Questionnaires were collected from 32,615 junior high school students and 48,707 senior high school students. Results: The smoking prevalence of students with high mobile phone bill was more likely to be high, and that of students who used mobile phones costing 10,000 yen and over per month was especially high. When "quitters" were defined as students who had tried smoking but were not smoking at the time of survey, the proportion of quitters decreased as the mobile phone bill increased. The proportion of students who had smoking friends increased with the increase in the mobile phone bill per month. Conclusion: The hypothesis that the decrease in smoking prevalence among Japanese adolescents that has been observed in recent years is due to a mobile phone use can be rejected.

The study purpose was to investigate psychosocial factors related to smoking among adolescent boys. The Theory of Planned Behavior provide the basis for the study. Twenty-five attitudinal beliefs, 9 normative beliefs and 20control beliefs were identified through questionnaire development. The data were analyzed using t-test and χ2-test. Thirty-three percent of 300 students were smokers. Most of the beliefs examined were significantly different between smokers(n=92) and nonsmokers(n=92). With respect to attitudinal beliefs, smokers responded less negatively on the items of bad health effects of smoking such as sore throat, headache, chest pain, risk of cancer and bad blood circulation(p<0.001), and decreased physical strength(p<0.05). Smokers believed less negatively on the items that smoking leads to bothering others, bad breath, yellow teeth and making them spend money(p<0.001). In contrast, smokers felt more positively on smoking as a means of stress management, relaxing, helping digestion(P<0.001). Smokers felt less pressure for not smoking from significant others. Especially mother, siblings, friends, girl friends, seniors of school were important sources of influence regarding subject's smoking. Smokers felt less confident in controlling the urge to smoke in several situations including; when they were with friends or asked to smoke by friends; after the meal, or drinking; when they were bored or stressed, upset, and when they felt unstable(p<0.001). Smokers also scored lower on specific skills to quit or control the urge to smoke as well as overall perceived control, compared to nonsmokers(p<0.001). These results suggest that interventions for adolescents incorporate diverse strategies to increase the perceived control over smoking in specific situations as well as overall perceived control, to help them realize and modify attitudinal beliefs, and to elicit support from significant others for not smoking.

Purpose: The purpose of this study was to investigate the combined influence of the frequency and the intensity of smoking on suicidal ideation and attempts in Korean high school students. Methods: This cross sectional study used secondary data from the 2014 Adolescent Health Behavior Online Survey. A total of 35,094 high school students were included in the study. The study set up two categories for the frequency of smoking - intermittent and daily - and another two for the intensity of smoking - heavy and light. Complex samples logistic regression was used to analyze the combined influence of smoking frequency and intensity on suicidal ideation and attempts. Results: Regardless of frequency and intensity, smoking was more likely to increase suicidal ideation and attempts than non-smoking. Among smokers, intermittent heavy smokers (suicidal ideation: Adjusted Odds Ratio [AOR]: 1.406, 95% Confidence Interval [CI]: 1.015~2.161, p=.012; suicidal attempts: AOR: 2.977, 95% CI: 1.814~4.886, p<.001) or daily heavy smokers (suicidal ideation: AOR: 1.274, 95% CI: 1.017~1.596, p=.035; suicidal attempts: AOR: 1.717, 95% CI: 1.250~2.359, p=.001) had significantly higher odds of suicidal ideation and attempts than intermittent light smokers. Conclusion: Based on the results, smoking prevention and cessation are essential to preventing suicides in adolescents. Especially, smoking intervention programs are needed to reduce smoking intensity in smokers.
