Effect of secondhand smoking on gingival pain and bleeding in non-smoking adolescents in South Korea / 대한구강보건학회지

ABSTRACT

Objectives@#This study aimed to identifying the relationship between exposure to secondhand smoking and oral diseases in adolescents, based on the web-based youth health risk behavior survey from 2020. @*Methods@#Among the 54,948 adolescent respondents to the 16th youth health risk behavior survey in 2020, this study included a total of 48,867 non-smoking adolescent participants who had never used regular cigarettes, vapes, or e-cigarettes. Analysis of the complex sample survey data was performed by applying weights according to the complex sample provided by the Korea Disease Control and Prevention Agency. Cross-tabulation analysis by complex sampling using the RaoScott chi-square test and complex-sample t-test was then performed to identify the relationship between subject characteristics and gingival pain and bleeding prevalence. Finally, a binary logistic regression analysis was performed to determine the effects of secondhand smoking on symptoms of gingival pain and bleeding in non-smoking adolescents. Data were analyzed using SPSS 26.0 version, and the statistical significance level was defined as P<0.05. @*Results@#Among the participants, periodontal disease symptoms were reported 1.201 times (95% confidence interval [CI] 1.101-1.310) more often in those with exposure to secondhand smoking exposure at home and 1.281 times (95% CI 1.173-1.398) more often in those with exposure to secondhand smoking in public places than in those who did not report exposure to secondhand smoking. @*Conclusions@#The study results suggest that exposure to secondhand smoking increases the risk of gingival pain and bleeding in non-smoking South Korean adolescents and is a risk factor for periodontal diseases.
