Objectives: This study was conducted to observe recent changes in adolescents' dietary behavior and indirectly evaluate the effects of the government's nutritional policies in Korea. Methods: We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents' dietary behaviors during the same periods. Results: The significant linear trends were observed in all dietary behaviors (p<0.05). Overall, all behaviors except the fruit intake rate were desirably changed during five years but undesirable changes were observed between 2008 and 2009 in all behaviors. Within those periods, several policies were implemented including 'Ban on carbonated-beverages in school', 'Green Food Zone', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn't influence the prevalence of dietary behaviors because they were conducted to too limited persons. Polices on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn't come to a conclusion because of too short period after full implementation. Conclusions: Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.

Objectives: This study was performed to consider the association between Internet using time for non-educational purposes and adolescent health, and to examine how health status differs between Internet users and non-users. Methods: We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A total of 75 066 adolescents were categorized into four groups according to their Internet using time excluding using for educational purposes: non-Internet users (NIUs), occasional Internet users (OIUs) (<1 h/d), moderate Internet users (MIUs) (${\geq}1$ and <2 h/d), and heavy Internet users (HIUs) (${\geq}2$ h/d). Health factors included eight health risk behavior indices, four mental health indices and six physical health indices. Results: The distribution of Internet use was as follows: NIUs 17.4%, OIUs 68.1%, MIUs 12.7%, and HIUs 1.7%. In multivariate analysis, using OIUs as a reference, U- or J-shaped associations were observed for five health risk behavior indices (current smoking, current drinking, drug abuse, sexual intercourse, sedentary behavior on weekdays) and four mental health indices (stressed, depressed, suicidal ideation, attempted suicide) in both genders. After removing confounding effects, including age, region, school type, subjective school record, subjective economic status, presence of parents, living with family, and sedentary behavior, these associations were still observed. Conclusions: Health professionals should consider both Internet non-users (for non-educational purposes) and heavy users to be high-risk groups in terms of health status. Also, more well-designed studies are needed to clarify what factors are working in these nonlinear associations.

There is growing evidence that substance use such as tobacco or alcohol consumption influences health disparity among adolescents. Previous research papers have shown an inconsistency in the relationship between socio-economic status (SES) and substance use in adolescents. However, little is known about socio-economic differences in unhealthy behaviors among Korean adolescents. The purpose of the present study is to explore associations between SES and substance use in Korean adolescents. The analysis was performed using data from the 2009 Korean Youth Risk Behavior Web-based Survey (YRBS), which included a nationally representative sample of middle and high school students. Drinking/heavy drinking and smoking/daily smoking behavior indices were used for dependent variables, and perceived economic status, family affluence score, parents' education were used for independent variables. Chi-square test were used to compare tobacco and alcohol consumption among 3 SES groups. Logistic regression models were used to identify statistically significant socio-economic factors after adjusting other covariates. Higher perceived economic status and higher family affluence were associated with higher rates of smoking, daily smoking, drinking, and heavy drinking, while lower level of parents' education was related to higher use of tobacco and alcohol. Socio-economic status significantly influences health behaviors in adolescents, and it may consequently affect health disparity in their adulthood. Therefore, there is a need of continuous monitoring and follow-up research of health disparity among adolescents.

Objectives: The purpose of this study was to investigate the hygiene behaviors according to obesity in adolescents and to provide basic data for school health project. Methods: The data from the 10th Korea Youth Risk Behavior Web-based Survey(KYRBWS) were analyzed by STATA 13.0 statistical packages. The demographic characteristics were analyzed by frequency analysis. The relationship between obesity and hygiene behaviors according to demographic characteristics were analyzed by chi-square test. Pearson's correlation coefficient was used for the correlation among the variables. Multivariate logistic regression analysis was performed to examine the effect of obesity on the hand washing and oral hygiene behaviors. The significance level for significance was set at 0.05. Results: Obesity, hand washing before eating and hand washing after using the bathroom were significant negative correlation. Hand washing before eating and hand washing after using the bathroom were significant positive correlation. Hand washing after using the bathroom were positive correlation with toothbrushing after lunch. Washing before eating was 1.079 times higher than that of obese people(p<0.05), and toothbrushing after lunch was higher by 1.298 times in Odds ratio than normal weight(p<0.001). Conclusions: There is a need to develop a school dental health program by collecting hygiene behaviors such as obesity, hand washing, and brushing after lunch.

Purpose: Breakfast is the most important meal to provide energy for the day. Breakfast is especially important to give enough nutritional support to children and adolescents for their physical growth and sexual development. Sleep-related factors like average sleep duration and wake up time would mostly be associated with regular breakfast. This study aimed to investigate the effect of sleep on regular breakfast consumption in Korean adolescents. Methods: The study used the data from the 12th Korea Youth Risk Behavior Web-based Survey (KYRBS-XII) conducted in 2016 by the Korea Centers for Disease Control and Prevention. The data of 62,820 subjects (middle/high school students) were included in the final analysis. The study examined the factors related to regular breakfast, focusing on weekday average sleep duration and wake up time of middle school students and high school students, respectively. Results: Regular breakfast consumption was shown to have a statistically significant association with high economic status, nutritional education, weekday average sleep duration, wake up time, and subjective sleep satisfaction in the multivariate logistic regression. Regardless of the school level, regular breakfast consumption was significantly associated with early wake up time. As to the effect of weekday average sleep duration on regular breakfast consumption, it showed some different results depending on the school level. Conclusion: Regular breakfast consumption of Korean adolescents was related to weekday average sleep duration and wake up time. Having breakfast regularly was affected by both adequate weekday average sleep duration and early wake up time.

Objectives: The purpose of this study was to evaluate the association between Internet use and oral health behaviors in Korean adolescents. Methods: This study used the 13th Korea Youth Risk Behavior Web-based Survey (2017) to find an association between Internet use and oral health behaviors. The total number of study subjects was 54,603. A chi-square test and multiple logistic regression analyses were used to estimate the association between Internet use and oral health behaviors. Results: Internet use was significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of frequency of toothbrushing more than three times daily and use of oral hygiene devices was increased among female, higher school record, and higher economic status participants significantly (p<0.001). Oral symptoms experienced were significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of the toothbrushing more than three times daily and toothbrushing after lunch groups was the highest in the group with less than one hour of Internet use, but the rate of oral symptoms experienced was the highest in the group with over five hours of Internet use. The risk of toothbrushing less than twice daily was 1.61 times higher in the group with over five hours of Internet use, and the risk of not brushing after lunch was significantly higher (1.52 times) in the over five hours group. The risk of not using oral hygiene devices was the highest (1.22 times) in the less than five hours group, and the risk of oral symptoms experiences was 1.40 times higher in the more than five hours group. Conclusions: Internet use was related to oral health behaviors in adolescents. Appropriate Internet use and awareness of oral health care are needed among adolescents.
