Purpose: This study was done to explore the rates and methods of contraception among Korean adolescents from 2007 to 2009. Methods: The study was a descriptive study. The data were taken from a web-based survey on risk behavior of Korean youth that was conducted between 2007 and 2009 by the Korea Centers for Disease Control and Prevention. Results: Among adolescents, 4.7% in 2007, 4.6% in 2008, and 4.7% in 2009 reported having had sexual intercourse. In those who had sexual experiences, less than 30% reported consistent use of contraception, whereas more than 45% report no contraceptive use at all. A condom was the most frequently used contraceptive method and its use has increased continuously among contraceptive users. Some of the adolescents were, nevertheless, using unreliable methods such as withdrawal or the rhythm method. Conclusion: The results of this study indicate that most adolescents are not using contraception consistently and some were relying on unreliable contraceptive methods. Efforts to raise awareness about consistent and correct contraceptive use and the importance of dual protection are essential.

Background: The purpose of the present study was to confirm the degree of physical activity and oral health behaviors of adolescents, and to investigate the relationship between them. Methods: The present study utilized data from the 15th (2019) Korea Youth Risk Behavior Web-Based Survey data, which included a total of 57,303 adolescents for analysis. Statistical analysis was performed using PASW Statistics 21.0. The significance level for significance was set at 0.05. Results: The rate of toothbrushing before sleeping was 1.152 times higher in the group that performed muscle strengthening exercises more than 3 times a week than in the group that did not (p < 0.001). The rate of use of oral hygiene products was 1.246 times higher in the group that performed physical activity for 60 min or more every day than in the group that did not, and 1.207 times higher in the group that performed muscle strength exercise at least 3 times a week than in the group that did not (p < 0.001). Conclusions: Adolescents who engaged in physical activities had a high rate of practice for some oral health behaviors. These results suggested that the group with positive health behaviors has a higher rate of oral health behavior practice, showing that health behaviors are highly interrelated.

BACKGROUND/OBJECTIVES: Body shape misperception (BSM) is the disagreement between the subjectively perceived body size and body mass index. This study investigated the association between BSM and unhealthy eating behaviors (UEB) among Korean adolescents. SUBJECTS/METHODS: This cross-sectional study used data from the 2019 Korea Youth Risk Behavior Web-based Survey with 55,748 participants. UEB were measured according to the weekly consumption frequency of caffeinated energy drinks, fast food, carbonated beverages, and sugar-sweetened beverages. The covariates included demographic and socioeconomic characteristics and health-related factors. Multiple logistic regression analysis determined the association between BSM and UEB. RESULTS: Among the participants, 37,607 (67.5%) reported UEB. The gap between UEB among those with BSM was the largest between the underestimated and accurately estimated groups. Participants who underestimated their body shape were likelier to engage in UEB (adjusted odds ratio [AOR], 1.18; 95% confidence interval [CI], 1.11-1.25). Both sexes with underestimation of body size showed an association with UEB compared to those with accurate estimations (girls: AOR, 1.19; 95% CI, 1.09-1.30; boys: AOR, 1.16; 95% CI, 1.08-1.26). CONCLUSIONS: Underestimating body shape can provoke UEB among Korean adolescents. The need for appropriate school health interventional programs to prevent underestimating body shape is emphasized to avoid UEB.

The purpose of this study was to investigate the association between antioxidant food intake pattern and asthma control status in Korean adolescents. This study was conducted using data from 1,578 patients diagnosed with asthma among the participants in the 11th online health behavior survey. Statistical analyses were performed for sociodemographic variables, known risk factors for asthma worsening, and all variables which were related to food intake pattern. For final decision, logistic regression analysis was used to estimate the associations between antioxidant food intake and asthma worsening. Male gender and smoking experiences were associated with asthma exacerbation. Low intake of antioxidant foods status also significantly increased asthma exacerbations. Antioxidant food intake and smoking prevention education is important for adolescent asthma patients. It is highly needed to recommend taking fruits and vegetables properly.

Purpose: By analyzing factors related to suicide ideation of Korean middle and high school students, the purpose of this study was to multi-dimensionally understand suicide ideation of Korean middle and high school students and arrange the plans to prevent suicide. Methods: This study used and analyzed the data on ‘The 3rd (Year2007) Korea Youth Health Risk Behavior Web-based Survey (KYHRBWS)' conducted by the Korea Centers for Disease Control and Prevention. In this study, we analyzed 74,698 respondents in total. SPSS 12.0 Program was used to analyze the survey. Descriptive statistics, Chi-Square Test and multivariate logistic regression were also used as research methods. Results: 23.8% of the Korean middle and high school students had suicide ideation during the last one year. Girls had higher possibility of suicide ideation by 1.51 times compared to boys. Students with poor academic achievement had more suicide ideation. In terms of health characteristics, students who perceived themselves as not healthy, and students with short weekday sleeping hours, more drinking experience and more smoking experience had more suicide ideation than others. Furthermore, students who perceived themselves as overweight or obese had more suicide ideation than other students. In terms of mental characteristics, students with high level of stress, low level of happiness and depression had more suicide ideation. Conclusion: As a result of this study, we found out that the factor that had the biggest influence on suicide ideation of Korean middle and high school students was depression. Consequently, active supports and policies to decrease suicide ideation of Korean middle and high school students are necessary. Therefore, active interviews, education for suicide prevention, and periodical screening inspection should be introduced in schools.

Objectives: This study aimed to determine whether adolescents with allergic rhinitis are at an increased risk of stomatitis and to ascertain possible sex-specific differences. Methods: The data for this cross-sectional study was obtained from the 18th Korea Youth Risk Behavior Web-based Survey (2022). Of the 56,213 students surveyed, 51,850 (boys 26,397 and girls 25,453) were included in the final analyses. Multivariate logistic regression was performed to identify the impact of allergic rhinitis on the risk of stomatitis among Korean adolescents. Results: In Model II, which was adjusted for allergic disease, boys with allergic rhinitis had a 1.53-fold (adjusted odds ratio [aOR]=1.53, 95% confidence interval [CI]=1.40-1.67), and girls had a 1.35-fold (aOR=1.35, CI=1.25-1.46) elevated risk of stomatitis than in those without. In Model III, after adjusting for all covariates, boys with allergic rhinitis had a 1.48-fold (aOR=1.48, CI=1.36-1.62) elevated risk of stomatitis than in those without, and girls had a 1.32-fold (aOR=1.32, CI=1.22-1.43) elevated risk, which remained statistically significant after adjusting for covariates. Therefore, allergic rhinitis in adolescents exerts a detrimental effect on the risk of experiencing stomatitis symptoms; the risk was higher in boys than in girls. Conclusions: These findings suggest that oral health care attention and intervention are needed for adolescents with allergic rhinitis.

This study investigated changes in the youth smoking rate and smoking cessation rates before and after a cigarette price increase in 2015. Specifically, the changes in smoking rate, smoking cessation attempt rate, selection rate and amount of smoking were investigated using primary data pertaining to Korean Youth Risk Behavior obtained from a web-based survey of youth general characteristics, mental health, subjective grade, drinking and smoking related characteristics before and after a cigarette price increase. To accomplish this, 800 middle school and high school students in 9th (2013), 10th (2014), 11th (2015) were surveyed. The current youth smoking rate was slightly decreased from 9.7% in 2013 to 9.2% in 2014, while the smoking rate in 2015 decreased significantly by 15.2% after the cigarette price increased to 7.8%. These results confirmed that increasing cigarette price is very effective at decreasing youth smoking rate, providing motivation to stop smoking and preventing smoking. The prevention of smoking and inducement to stop smoking during adolescence is very important because the majority of teenage smokers continue smoking into their adulthood. In addition to expanding a completely non-smoking area and a comprehensive ban on tobacco advertising, promotion and sponsorship should be urgently sought, and the effect can be maximized when the WHO FCTC faithfully implements the already-founded treaty.

Background: Multicultural families are constantly on the rise as marriage migrants and foreign workers increase. Multicultural families appear to record poor health levels compared to native families. As health is a social issue, children of surviving generations of multicultural families are also a growing interest. This study was conducted to confirm the effect of multicultural families and parents' educational level on the scaling experience of children. Methods: For this study, the 2016~2018 Korea Youth Risk Behavior Web-based Survey data were used. In order to make the two groups of adolescents belonging to multicultural and native families similar, a total of 5,362 people were included in the survey, consisting of 2,681 individuals each from multicultural and native families using the propensity score matching method. Logistic analysis was performed to identify factors influencing the scaling experience of adolescent children. Results: The results confirm that, even after controlling for factors such as parents' educational level, household income, and children's oral health behavior, parents' nationality appeared to have a statistically significant effect on their children's scaling experience. In addition, it was confirmed that the experience of oral health education had a significant effect. Conclusion: Cultural heterogeneity and the lack of adequate language ability of immigrants affects health behavior and medical accessibility. Therefore, children from multicultural families are more likely to be exposed to unhealthy environments compared to the children of native Korean families. Based on an understanding of the socioeconomic multicultural background of individuals, education and public policy should be prepared to improve the awareness for the need for preventive oral health and provide unhindered accessibility to dental services.

Objectives: This study was performed to examine the relationship between health behaviors, living environment, and asthma in adolescents in Korea. Methods: Information on adolescents' characteristics, including demographic factors, health behaviors, and doctor's diagnosis of asthma was obtained from the Korean Youth Risk Behavior Web-based Survey (2015). In total, 68,043 middle and high school students participated. Environmental characteristics, including city park area and outdoor PM₁₀ concentrations in 2015 were obtained from the Korean Statistical Information Service. The adolescents' and environmental characteristics were merged by local information. Multiple logistic regression models were used to investigate the risk factors affecting asthma in adolescents. Results: The prevalence of asthma in adolescents in 2015 was 8.8%. In the multiple logistic regression analysis, adolescents who were male, attended middle school, suffered obesity, experienced tobacco smoking, had physical activity levels of 2 to 4 days, had higher stress levels, and lived in areas with outdoor PM₁₀ concentrations more than 47 ㎍/㎥ were more likely to have asthma, while adolescents who had middle levels of family economic status were less likely to do so. Conclusions: The fact that PM₁₀ concentration can affect asthma is an important point in this study. Risk factors identified in this study could be used as basic data for the prevention and management of asthma in Korea.

Purpose: This study aims at identifying individual- and school-level factors associated with unintentional injuries to Korean adolescents at school by applying multilevel modeling. Methods: From the database of the eleventh Korea Youth Risk Behavior Web-based Survey (KYRBS), the researchers selected 68,043 adolescents from the $7^{th}$ to the $12^{th}$ grades. Data were analyzed using ${\chi}^2$ test for prevalence and multilevel modeling for related factors of unintentional injuries at school. Results: About 22.9 percent of the adolescents had treatment experiences for unintentional injuries at school in the past 12 months. At the individual level, the significant factors associated with unintentional injuries at school included gender, grade, academic achievement, current smoking, alcohol consumption, frequency of high caffeine intake, depression, and relief of fatigue after sleep. At the group level, the significant factors included number of physical education per week and safety education. Conclusion: School based injury prevention programs should be sensitive to both individual- and school-level factors associated with unintentional injury at school among Korean adolescents.
