Objectives: The purpose of this study was to examine the relationship between stress and halitosis in a representative sample of Korean adolescents. Methods: This study was based on the 15th Korea Youth Risk Behavior Survey (2019). The final participation rate in the survey was 95.3%; 57,303 out of 60,100 (95.3%) adolescents aged 13-18 years were selected. Multiple logistic regression with complex samples was performed to identify the correlation between stress and halitosis. Stress level was classified as 'very much', 'a little', and 'not much' and halitosis was defined as the presence of an unpleasant odor in the oral cavity. Results: The prevalence of halitosis among students was 21.3%. As a result of multiple regression analysis, the 'a little' [odds ratio (OR); 1.39, 95% confidence interval (CI); 1.29-1.49] and 'very much' stress group (OR; 1.78, 95% CI; 1.66-1.90) exhibited significantly higher risk of halitosis than the 'not much' stress group. Conclusions: A significant correlation between stress and halitosis exists among Korean adolescents. Therefore, psychological factors such as stress should be considered in managing halitosis in adolescents.

본 연구의 목적은 청소년 남학생 흡연과 가족구성원의 흡연의 관련성을 분석하기 위함이다. '제14차(2018년) 청소년건강행태조사'에 응답한 27,276명을 이용하여 빈도분석, 교차분석, 다중 로지스틱 회귀분석을 실시하였다. 남학생 중 비흡연율은 91.5%, 흡연율은 8.5%(가끔 흡연함 2.5%, 자주 흡연함 6.0%)이다. 연구결과, 가족구성원의 흡연자 수에 따른 남학생의 흡연 상태는 유의한 차이가 있다(p<0.001). 인구사회학적 특성에 따른 흡연은 학년, 학업성적, 경제상태, 아버지 학력, 어머니 학력에서 유의한 차이가 있고(p<0.001), 건강행태관련 특성에 따른 흡연은 음주 정도, 자살 생각률, 우울감 경험률, 스트레스 정도, 아침식사 빈도, 수면 후 피로회복 정도, 주관적 건강 인지 정도에서 유의한 차이가 있다(p<0.001). 남학생의 흡연가능성은 가족구성원 흡연자가 1명일 때보다 가족구성원 흡연자가 2명이상일 때 더 높다(p<0.001). 본 연구의 의의는 남학생 흡연이 가족구성원 흡연상태에 따라 영향을 받는다는 것을 확인하였으며 이러한 연구결과는 청소년 흡연의 예방 및 금연사업을 구성할 때 가족 흡연자의 금연 사업을 병행하여 설계한다면 좋은 효과를 거둘 수 있음을 시사한다.

Objectives: Following the coronavirus disease 2019 (COVID-19) pandemic, adolescents have experienced decreased physical activity and a decline in mental health. This study analyzed the association between changes in depressed mood after the COVID-19 pandemic and physical activity among adolescents. Methods: The analysis was based on the results of the 17th Youth Health Behavior Online Survey conducted in 2021, which included 54848 middle and high school students in South Korea. Information on physical activity included low-intensity physical activity lasting >60 min/day, high-intensity physical activity, and strength training exercises. A logistic regression analysis was performed to evaluate the association between physical activity and changes in depression after the COVID-19 pandemic. Results: After adjusting for sociodemographic characteristics and previous depression, adolescents who performed strength training exercises more than once per week had a 0.95-fold lower risk (odds ratio [OR]=0.948, 95% confidence interval [CI]=0.905-0.994, p=0.027) of increasing depression after the COVID-19 pandemic, while the risk of decreasing depression increased by 1.22-fold (OR=1.215, 95% CI=1.131-1.305, p<0.001). The results were not significant for low-intensity physical activity for >60 min/day and high-intensity physical activity. Conclusion: Strength-training exercises are significantly associated with the prevention of depression among adolescents following the COVID-19 pandemic.

BACKGROUND/OBJECTIVES: Nutrition knowledge has been reported to have a weak positive effect on healthy eating behavior. This study aimed to determine if there was a difference in nutrition knowledge depending on the choice of science subject in high school and whether that affected the actual eating habits of college students in Japan. SUBJECTS/METHODS: The subjects were 514 college students, the majority first-year students, in 3 cities in Japan. A questionnaire survey was conducted on elective subjects in science in high school, diet (11 items), lifestyle (5 items), and nutrition knowledge (34 questions). The preliminary survey was conducted on 47 students in the fall of 2019, and the full-scale survey was conducted in May-June and October-November 2021 at the end of lectures for the first-year students. RESULTS: The students in the high-score group (24-31 points, n = 180) had a higher intake of vegetables (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.12-2.82; P = 0.015) and breakfast (OR, 1.64; 95% CI, 1.03-2.60; P = 0.035), and a reduced intake of fast food (OR, 0.27; 95% CI, 0.14-0.51; P < 0.001) than those in the low-score group (6-19 points, n = 150). Only the biology and chemistry students had significantly higher nutrition scores than the other groups (all: P < 0.001), but no significant difference was found between the other groups. Understanding nutrition learned in elementary and junior high school is appropriate, while molecular structure, recommended amount, and food poisoning were insufficient. CONCLUSIONS: Knowledge of nutrition appears to have a positive effect on the actual eating habits of college students. Although biology and chemistry in high school may help students understand the foundations of good nutrition, specialized food education may be required to make informed dietary choices.

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.

Objectives: This study explored the prevalence and predictors of alcohol and cannabis co-use among 9263 Filipino adolescents, using data from the 2019 Global School-based Student Health Survey (GSHS). Methods: We conducted a cross-sectional secondary analysis of the GSHS, targeting adolescents aged 13-17 years and excluding cases with incomplete data on alcohol and cannabis use. Our analysis employed the bivariate chi-square test of independence and multivariable logistic regression using Stata version 18 to identify significant predictors of co-use, with a p-value threshold set at 0.05. Results: The weighted prevalence of co-users was 4.2% (95% confidence interval [CI], 3.4 to 5.3). Significant predictors included male sex (adjusted odds ratio [aOR], 4.50; 95% CI, 3.31 to 6.10; p<0.001) and being in a lower academic year, specifically grade 7 (aOR, 4.08; 95% CI, 2.39 to 6.99; p<0.001) and grade 8 (aOR, 2.20; 95% CI, 1.30 to 3.72; p=0.003). Poor sleep quality was also a significant predictor (aOR, 1.77; 95% CI, 1.29 to 2.44; p<0.001), as was a history of attempted suicide (aOR, 5.31; 95% CI, 4.00 to 7.06; p<0.001). Physical inactivity was associated with lower odds of co-use (aOR, 0.45; 95% CI, 0.33 to 0.62; p<0.001). Additionally, non-attendance of physical education classes (aOR, 1.48; 95% CI, 1.06 to 2.05; p=0.021), infrequent unapproved parental checks (aOR, 1.37; 95% CI, 1.04 to 1.80; p=0.024), and lower parental awareness of free-time activities (aOR, 0.63; 95% CI, 0.45 to 0.87; p=0.005) were associated with higher odds of co-use. Factors not significantly linked to co-use included age group, being in grade 9, always feeling lonely, having no close friends, being bullied outside school, and whether a parent or guardian understood the adolescent's worries. Conclusions: The findings highlight the critical need for comprehensive interventions in the Philippines, addressing not only physical inactivity and parental monitoring but also focusing on sex, academic grade, participation in physical education classes, sleep quality, and suicide attempt history, to effectively reduce alcohol and cannabis co-use among adolescents.

본 연구 목적은 청소년 자살시도자의 양상을 분석하고, 개인심리(주관적 우울감, 주관적 스트레스), 건강상태(주관적 건강인식, BMI), 주관적 학업성적이 청소년 자살시도 유형(계획적 자살시도자와 충동적 자살시도자)에 미치는 영향력을 알아보았다. 이를 위해 제 15차(2019년) 청소건강행태조사 원시자료를 사용하여 위계적 로지스틱 회귀분석을 하였다. 연구결과는 다음과 같다. 첫째, 청소년 자살시도자의 양상을 살펴본 결과, 청소년 자살시도자 1,731명중 계획적 자살시도자가 1,575명(91%)으로 충동적 자살시도자 156명(9%)에 비해 월등히 높게 나타났다. 성별을 살펴보면, 여성(67.3%)이 남성(32.5%)에 비해 자살시도가 높게 나타났고, 학교유형별로 보면 중학생(62%)이 고등학생(38%)에 비해 높은 자살시도율을 보였다. 둘째, 자살시도 유형에 유의미한 영향을 미치는 변수들은 '주관적 우울감', '주관적 스트레스', '주관적 건강인식'이었다. 우울감을 경험한 청소년의 경우 그렇지 않은 학생들에 비해 계획적 자살시도를 실행할 비율이 높게 나타났다. 스트레스를 많이 느끼는 청소년의 경우에도 계획적 자살시도자가 높은 것으로 나타났다. 주관적 건강인식의 경우 충동적 자살시도자가 계획적 자살시도자와 비교하여 1.32배 건강하다고 생각하는 것으로 나타나 건강하다고 생각하지 않은 청소년의 경우 계획적 자살시도가 높은 것으로 나타났다. 반면에 BMI, 주관적 학업성적의 경우 청소년들의 자살시도에 유의미한 영향을 미치지는 않았다. 이러한 연구결과를 기초로 가정과수업이나 창의적 체험활동에서 잠재적 청소년 자살시도 예방을 위한 방안을 제안하였다.
