Objectives: The aim of this study was to investigate trends of oral health behaviors in Korean adolescents. Methods: From the 2005 to 2017 Korea Youth Risk Behavior web-based Survey (KYRBS) Secondary Data (study to 748,461). Independent variables were the year, gender, grade, and living area. Dependent variables were the rate of tooth-brushing after lunch, scaling, use of sealant, and oral health education within 1 year. Chi-squire tests were used to estimate the rate of oral health behaviors and trends. In addition, multiple logistic regression analysis was used to estimate the association between socio-economic characteristics and oral health behaviors. The analyses were conducted using IBM SPSS statistics 21 (version 21.0, IBM Corporation, New York, NY, USA). Results: The rate of tooth-brushing after lunch and use of sealant have significantly increased every year. Oral health behaviors were significantly associated with socio-economic characteristics. The rate of oral health education was higher among males than females, which was in contrast to other oral health behaviors. The scores for tooth-brushing after lunch, use of sealant, and scaling in females were 2.33 (95% CI; 2.27-2.40), 1.31 (95% CI; 1.29-1.33), and 1.20 (95% CI; 1.18-1.22), which were higher than those in males. The score for use of sealant in the highest household economy group was 1.13 (95% CI; 1.10-1.17), which was higher than the lowest economy group. Conclusions: We found positive trends of oral health behaviors in Korean adolescents.

Background: This study aimed to demonstrate the association between the education level of parents and adolescent depression feeling. Methods: We used the chi-square test and the multiple logistic regression model to analyze the data of the "Korean Youth Health Behavior Survey in 2018" (n=43,220) conducted by the Korea Centers for Disease Control and Prevention. Results: As a result of the analysis, a group whose parents' education level is 'above the university graduation (including the graduation of the college)' had statistically significant experience of depression than a group whose parents' education level is 'high school graduation.' Conclusion: When preparing a policy on adolescent depression feeling, we need to consider the association between the education level of parents and adolescent depression feeling. Especially, a higher level of education of parents needs attention and management to foster positive mental health rather than excessive academic pressure, especially in the parent-child relationship of the same gender.

Objectives: The purpose of this study was to investigate the relationship between oral health factors and suicidal ideation in adolescents in order to provide basic data for adolescent suicide prevention and oral health promotion. Methods: This study used data from the Korea Youth Risk Behavior Web-Based Survey held in 2017, in which a total of 62,276 youth participated. Data were analyzed by SPSS Ver. 22.0. Complex logistic regression analysis was used to analyze oral health factors related to suicidal ideation. Results: The effects of oral health on male students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.01), while suicidal ideation was increased in individuals who had experienced scaling within the past year (p<0.001), or, among experiences of oral disease within the last year, had reported prickling and throbbing pain (p<0.001), pain on the tongue and inside the cheeks (p<0.001), or bad breath (p<0.001). The effects of oral health on female students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.001), while suicidal ideation was increased in individuals who, among experiences of oral disease within the last year, had reported pain when chewing (p<0.001), pain on the tongue and inside the cheeks (p<0.01), or bad breath (p<0.001). Conclusions: The above results demonstrate that adolescent suicidal ideation and oral health factors are correlated, and it will be necessary to incorporate oral health interventions when planning or developing projects and programs for suicide prevention in adolescents.

Purpose: The objective of this study was to develop a predictive model for the sexual experiences of adolescents using the random forest method and to identify the "variable importance." Methods: The study utilized data from the 2019 to 2021 Korea Youth Risk Behavior Web-based Survey, which included 86,595 man and 80,504 woman participants. The number of independent variables stood at 44. SPSS was used to conduct Rao-Scott χ² tests and complex sample t-tests. Modeling was performed using the random forest algorithm in Python. Performance evaluation of each model included assessments of precision, recall, F1-score, receiver operating characteristics curve, and area under the curve calculations derived from the confusion matrix. Results: The prevalence of sexual experiences initially decreased during the COVID-19 pandemic, but later increased. "Variable importance" for predicting sexual experiences, ranked in the top six, included week and weekday sedentary time and internet usage time, followed by ease of cigarette purchase, age at first alcohol consumption, smoking initiation, breakfast consumption, and difficulty purchasing alcohol. Conclusion: Education and support programs for promoting adolescent sexual health, based on the top-ranking important variables, should be integrated with health behavior intervention programs addressing internet usage, smoking, and alcohol consumption. We recommend active utilization of the random forest analysis method to develop high-performance predictive models for effective disease prevention, treatment, and nursing care.
