Objectives: The aim of this study was to compare health related behaviors among adolescents in the rural area with those in the urban area in Korea. Methods: The data source was the Korea Youth Risk Behavior Web-based Survey in 2005. With two stage cluster sampling, a total of 58,224 sample was selected from 799 middle and high schools nationwide. The area was classified into county area, small to medium city, and large city, and then the county area was considered as a rural area. Data was analyzed with STATA 9.0 using the method of complex survey data analysis considering sampling weight, strata, and primary sampling unit. Results: The prevalence of health related behaviors among adolescents in the rural area was higher than the city area as following health behaviors: smoking behaviors of smoking experience, smoking experience before entrance to middle school; drinking behaviors of frequent drinking, high risk behaviors with drinking; dietary behaviors of omitting of lunch or dinner, less intake of fruits or milk, more intake of cooky; oral hygiene of less tooth brushing, less preventive oral care, more oral symptoms and less dentist visit; safety behaviors of less wearing of safety belt or protective device; general hygiene of less hand washing before meal or after visiting rest room. Conclusions: The health behaviors among adolescents in the rural area were generally poorer than the city area. The results showed national health program for adolescents should be conducted primarily for those in rural areas. Further study is needed to explore the factors related with the discrepancy of health behaviors between the rural and urban area.

Purpose: This study examined the frequency of sugar-sweetened beverage consumption in Korean adolescents and the major factors influencing the excessive consumption of sugar-sweetened beverages, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits. Methods: The analysis was performed using the data from the 2017 Korean Youth Risk Behavior Web-based Survey. The subjects included in the analysis were 30,885 middle school students and 31,391 high school students, totaling 62,276. The frequency of sugar-sweetened beverage consumption was calculated by summing the consumption frequencies of soda, high caffeine or energy drinks, and sweet beverages over the last 7 days. The Rao-Scott chi-square test, reflecting information on the sampling design, was used to test the differences in the rate of sugar-sweetened beverage consumption according to each factor. Logistic regression analysis was performed to examine the factors influencing the excessive consumption of sugar-sweetened beverages. Results: The rate of sweetened beverage consumption was higher in boys than in girls, in high school students than in middle school students, in students whose father's education level was lower, in those whose subjective academic performance was lower, and in those who smoked or consumed alcohol. In addition, the rate of sugar-sweetened beverage consumption was higher in those who experienced severe stress, suicidal ideation, sadness, or a sense of despair. The rate of sugar-sweetened beverage consumption was also high in those who skipped breakfast; who frequently consumed fast foods, ramen, or snacks; and who frequently ate meals at convenience stores, supermarkets, or school stores. Conclusion: The rate of sugar-sweetened beverage consumption in Korean adolescents is related to various factors, such as sociodemographic characteristics, health-related behaviors, psychological characteristics, and dietary habits.

The purpose of this study was to analyze the effects of middle school students' health factors and eating behaviors on their oral symptoms using the data from 30,885 students in the 13th Korea Youth Risk Behavior Web-Based Survey in 2017. The logistic regression for the effects of the health factors and eating behaviors on the oral symptoms were analyzed using a logistic regression method. The results showed that the groups of higher levels of achievement, and stress, lower daily frequency of tooth-brushing, and no intake of processing meat led to significantly higher levels for toothache and gingival pain recognition. Also, the higher halitosis recognizers had significantly higher levels of stress and the lower daily frequency of tooth-brushing. In conclusion, adolescents' health factors and eating behaviors affected their oral symptoms. This study is expected to help development of a oral health education program that can prevent these oral symptoms.

The purpose of this assessment was to provide the basic data for setting up education in terms of 'Hand wash' as one of the health plan & education programs for adolescents. The task analyzed the behavior of students regarding hand washing, which were ranged from middle school to high school. The SPSS 18.0 statistical program, frequency-test and cross-analysis were used for data analysis by 2011, 2012 and 2013, which were the recent 3 years, the Korea Youth Risk Behavior Web-based Survey data. In the data, the response of "Never washed" from students before having a meal accounted for 29.4% in 2011, 30.5% in 2012 and 18.5% in 2013, respectively. Unlike other subjects, these facts suggest that this kind of behavior should be considered significant under the assessment. By tracking the trend over three years, some facts were confirmed in that students living in the metropolitan and medium-sized cities were less likely to wash their hands than students in small- sized towns. In terms of gender, female students were less likely to wash their hands than male students. Regarding the type of school, more students in the public middle & high schools had a tendency to respond "Never hand wash" than the students in the special-purpose high schools. Furthermore, as the grade was increased in middle school and high school, students were less likely to wash their hands before meals in school. Therefore, Health promotion and health education for students should be conducted more carefully with more emphasis on this point.

Purpose: The purpose of this study was to identify the factors that influence the consumption of convenience foods among Korean adolescents. Methods: This study had a descriptive cross-sectional study. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. Convenience-food consumption was defined by frequency of adolescents consuming convenience foods obtained from convenience stores, supermarkets, and cafeterias over the previous 7 days. The analyzed variables were related to sociodemographic, mental health, and health behavior. The Rao-Scott χ² test was applied to examine the difference in the rate of consuming convenience foods obtained from convenience stores according to each factor. Hierarchical logistic regression was conducted to examine the factors that influence convenience-food consumption among Korean adolescents. Results: It was found that 29.1% of Korean adolescents consumed convenience foods obtained from convenience store more than three times per week. The significant influencing factors were female sex; low subjective academic achievement, and subjective household economic status; high perceived stress; low subjective sleep sufficiency; experience of depression; suicidal ideation; lower physical activity; skipping breakfast; lower consumptions of fruit, milk, and vegetables; higher consumptions of soda drinks, sweet drinks, caffeine, and fast food; lower water intake; current smoking and drinking; drug use; and experience of violence. Conclusion: These findings provide a better understanding of the sociodemographic, mental-health, and health-behavior factors that influence the consumption of convenience foods among Korean adolescents. We suggest that differentiated policies, strategies, and nutrition education need to be developed and implemented, in order to address the above-mentioned factors and thereby reduce such behaviors among Korean adolescents.

Objectives: The purpose of this study was to compare oral symptoms in middle school and high school students of multicultural and ordinary families in Korea. Methods: We used data from the web-based survey of the National 2014 Korean Youth Risk Behavior of Korean Center for Disease Control. A total of 71,174 subjects responded about their father or mother's Korean nationality. We classified a subject as an adolescent of a multicultural family if aparticipant's father or mother's nationality was not Korean. Data was analyzed using SPSS Ver. 19.0. Results: High school students of multicultural families have experienced more oral disease symptoms, compared to high school students of ordinary families. After adjusting general characteristics and oral health behaviors, high school students of multicultural families experienced 1.78 times higher frequency of oral disease symptoms compared to high school students of ordinary families. Conclusions: The family type and age characteristics of adolescents should be considered when establishing policies and institutions targeting adolescents to improve oral health.

The purpose of this study is to investigate factors related to substance use focusing on the sexual experiences and risky sexual behaviors among Korean adolescents. This study conducted with a secondary data analysis using the Seventh Korea Youth Risk Behavior Web-based Survey 2011 in South Korea. The study participants selected 75,643 Korean adolescents who were recruited anonymously through national web-based survey. Data were analyzed using descriptive statistics, rao-Scott ${\chi}^2$, and logistic regressions considering complex samples. Results indicated that substance use was significantly associated with sexual experiences such as sexual intercourse with the opposite sex (adjusted OR=5.691; 95% CI=4.223-7.670), sexual intercourse with the same sex (adjusted OR=21.180; 95% CI=14.704-30.507) and risky sexual behaviors such as sexual assaults (adjusted OR=9.936; 95% CI=7.217-13.680), date rape (adjusted OR=16.979; 95% CI=11.648-24.751), sexual intercourse after drinking (adjusted OR=6.564; 95% CI=3.986-10.810), unexpected pregnancies (adjusted OR=18.628; 95% CI=8.476-40.936), and sexually transmitted diseases (adjusted OR=21.872; 95% CI=13.920-34.367) in Korean adolescents. Findings of this study show that adolescents who use substances are more likely to engage in risky sexual behaviors. Therefore, intervention program should be designed to consider both substance use and sexual problems and to include the effective approaches at the family and school level.

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.

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.

Objectives: The aim of this study was to assess the association between the use of heated tobacco products (HTP) and suicidal behaviors such as suicidal ideation, suicide planning, and suicide attempts among adolescents in South Korea. Methods: The study used a cross-sectional design. Data was from the 15th Korea Youth Risk Behavior Web-based Survey (KYRBS) performed in 2019 by the Ministry of Education, Ministry of Health and Welfare, and Korean Center for Disease Control and Prevention. Heated tobacco product use was used as a main independent variable and suicide-related behaviors such as suicidal ideation, planning, and attempts were applied as dependent variables. Out of 60,100 students, 57,303 responded. Results: HTP use significantly increased the odds of a suicide attempt and suicide planning among adolescents. After controlling for confounders, when comparing 'current HTP users' with 'never HTP users', the adjusted odds ratio (OR) was 1.78 (95% confidence interval (CI): 1.38-2.30) for suicide attempts among adolescents. After controlling the confounders, comparing 'current HTP users' with 'never HTP users', the adjusted OR was 1.36 (95% CI: 1.06-1.73) for suicide planning among adolescents. For sadness/despair among adolescents, when comparing 'current HTP users' with 'never HTP users', the adjusted OR was 1.29 (95% CI: 1.11-1.50). However, HTP use had no significant association with suicidal ideation among adolescents. Conclusions: Current HTP users were more likely to attempt to commit suicide, and more likely to plan to commit suicide than never HTP users among adolescents. These results may be useful in developing a scientific basis for designing suicide prevention programs targeting adolescents.
