Objectives: Understanding recent trends in cigarette smoking among adolescents is important in order to develop strategies to prevent cigarette smoking. The aim of this study was to compare recent trends in cigarette smoking for adolescents living in rural areas, small towns and metropolitan cities in Korea. Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) from 2005 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Logistic regression models were used to evaluate significant linear time trends in cigarette smoking. The indicators of cigarette use behaviors were 'current smoking rate', 'frequent smoking rate', 'heavy smoking rate' and 'smoking experience rate before 13 years of age'. All analyses were conducted according to gender. Results: Statistically significant increasing trends in current smoking rate and frequent smoking rate were observed and borderline significant increasing trends in heavy smoking rate were shown among rural boys. Among metropolitan city boys, statistically significant increasing trends were also seen for frequent smoking. Statistically significant decreasing trends in current smoking rate were observed among small town and metropolitan city girls. Smoking experience rate before 13 years of age for rural girls decreased significantly. Conclusions: Cigarette smoking prevalence among adolescents in the rural areas has increased in the last five years especially among boys. Our findings suggest that anti-tobacco program for adolescents should be conducted primarily for those in rural areas.

Purpose: The purpose of this study was to develop a system dynamics model for adolescent obesity in Korea that could be used for obesity policy analysis. Methods: On the basis of the casual loop diagram, a model was developed by converting to stock and flow diagram. The Vensim DSS 5.0 program was used in the model development. We simulated method of moments to the calibration of this model with data from The Korea Youth Risk Behavior Web-based Survey 2005 to 2013. We ran the scenario simulation. Results: This model can be used to understand the current adolescent obesity rate, predict the future obesity rate, and be utilized as a tool for controlling the risk factors. The results of the model simulation match well with the data. It was identified that a proper model, able to predict obesity probability, was established. Conclusion: These results of stock and flow diagram modeling in adolescent obesity can be helpful in development of obesity by policy planners and other stakeholders to better anticipate the multiple effects of interventions in both the short and the long term. In the future we suggest the development of an expanded model based on this adolescent obesity model.

Purpose: The purpose of this study is to examine the effect of sleep duration on suicidal ideation in Korean adolescents. Methods: This study used the data drawn from Korea Youth Risk Behavior Web-Based Survey in 2013. A total data of 63,301 adolescents were included in the analysis. Included variables were general characteristics, health status variables, hours of sleep, and suicidal ideation. For sample description weighted percentage and means were used. Rao-Scott ${\chi}^2$ test and simple and multiple logistic regression with dummy variables were conducted with use of SAS 9.2. Results: Among general characteristics and health status variables, gender, grade, school level, school achievement, family's economic status, living with parents, subjective health, happiness, stress, and feeling of despair were found to be significantly related to suicidal ideation. Rates of having suicidal ideation were 22.4% in the case of students with less than 5 hours of sleep and 12.9% in students with 8 or more hours of sleep. After controlling general characteristics and subjectively perceived variables, hours of sleep was still significantly related to suicidal ideation. That is, compared to adolescents with 8 hours or more of sleep, those with less than 5 hours of sleep showed significantly higher risk for having suicidal ideation (adjusted odds ratio: 1.20, p<.001). Conclusion: These findings suggest that short sleep has negative effects on psychological health in adolescents. Particularly, less than 5 hours of sleep has harmful effect on adolescents' increased risk for having suicidal ideation.

Purpose: The purpose of this study was to identify 14 years of trends in sexual intercourse and sex education experiences among Korean adolescents from 2006 to 2019, based on online data. Methods: The study was a secondary analysis using the raw data of the 2^nd (2006) through 15^th (2019) Youth Risk Behavior Web-based Survey. The data of 504,105 male adolescents and 473,053 female adolescents were used for the analysis. A complex-sample cross-analysis (Rao-Scott χ² test) was performed to identify differences in sexual intercourse, sex education experience, and contraception over time, and logistic regression was performed to identify factors affecting adolescent sexual intercourse. Results: Sexual intercourse was found to increase as the year progressed. More high school students had sexual experiences than middle school students. Students who had ever smoked or drunk were more likely to have had sexual intercourse than the ones who had not. Students living with relatives or living in boarding houses or dormitories showed a higher rate of sexual intercourse than those living with family members. Students who never received sex education also showed a high rate of sexual intercourse. Conclusion: It is significant to grasp the trends in sexual intercourse, sex education experience, and contraception among adolescents over time. Providing adolescents with healthy sex education is becoming more and more important every year and health-related education including sex education that meets the need of teenagers should be incorporated into the regular curriculum.

Purpose: The purpose of this study was to investigate the association between sexual intercourse and experience of alcohol, tobacco, and drugs use among adolescents in South Korea. Methods: This study used the data of the Korea Youth Risk Behavior Web-based Survey from 2010 through 2014. The subjects of this study were 367,562 students (Male 187,610, Female 179,952). The subjects' general characteristics and their sexual experiences according to their general characteristics were analyzed using frequency analysis. The relationship between sexual intercourse and the use of alcohol, tobacco, and drugs was analyzed through multiple logistic regression. The analyses were conducted using SPSS 18.0. Results: According to the study, the significant predictors of sexual intercourse were gender, grade, parents' educational level, residence type, economic status, and substance abuse. Adolescents who had used alcohol, tobacco, and drugs were more likely to have had sexual intercourse than their peers who hadn't use the substances. Conclusion: The results suggest that factors that increase the risk of having premature sex should be managed and prevented systematically. Among the factors, in particular, drinking, smoking, and drug use require intensive management.

Objectives: This study aimed to investigate the effects of the amount and duration of smoking on gingival symptoms in adolescents. Methods: We used the web-based survey data of youth health behaviors from 2016 conducted by the Korean Centers for Disease Control and Prevention. The subjects of the study were 67,983 middle and high school students. Data analysis was performed using the SPSS Ver 20.0 program, and complex sample multivariate logistic regression analysis was performed to analyze gingival symptoms according to short- or long-term smoking habits. Results: In subjects with short-term smoking habits, there was no significant difference in gingival symptoms according to the smoking amount. However, after adjusting for socioeconomic characteristics and oral health behaviors in subjects with long-term smoking habits, a heavy smoking amount (${\geq}0.52PY$) had a 1.25 times higher effect than a light smoking amount (<0.52 PY) on gingival symptoms. Long-term heavy smoking (${\geq}0.52PY$) and low daily tooth-brushing frequency in high school students were factors affecting gingival symptoms. Conclusions: When conducting a project on the oral health of adolescents, it is argued that specific investigations and measures should be set up regarding health behavior factors, such as the amount and duration of smoking among adolescents.
