PURPOSE: This study aimed to examine the associations between participation in physical education (PE) classes and the psychological well-being and sleep satisfaction of Korean adolescents. METHODS: Cross-sectional data from 127,804 Korean adolescents (aged 12–18 years) who participated in the 2016 and 2017 Korea Youth Risk Behavior Web-based Surveys (KYRBS) were analyzed. The exploratory variable was the frequency of participation in PE classes every week, while the dependent variables included the psychological well-being and sleep satisfaction, as assessed by the KYRBS questionnaire. Sex- and grade-stratified logistic regression analyses were conducted to generate the odds ratios (ORs) and 95% confidence intervals (CI). RESULTS: Overall 16.9% of adolescents reported that they did not participate in PE classes while 33.0% reported participating for more than three times a week. After adjusting for the academic achievements, family’s economic status, consumption frequency of breakfast and highly caffeinated drinks, and physical activity level, a greater participation in the PE classes was found to be associated with happiness in a dose-response fashion in both sexes and grades (p<.05). As for stress, participation in the PE classes for more than three times a week was associated with less/no stress in boys (OR: 1.16, 95% CI: 1.02–1.31, p<.05) and high school students (OR: 1.22, 95% CI: 1.03–1.44, p<.05). Moreover, greater participation in the PE classes was associated with a lower odds of reporting sleep satisfaction in a linear fashion among high school students.
