INTRODUCTION: Inadequate sleep duration among adolescents is increasingly recognized as a significant public health concern, with potential associations with various environmental exposures. This study investigates the association between secondhand smoke (SHS) exposure and sleep duration in Korean adolescents.
METHODS: This study employed a pooled cross-sectional design using data from the nationally representative Korea Youth Risk Behavior Web-based Survey from 2021 to 2024 (n=195664). This study analyzed self-reported sleep duration (hours/minutes) from the Korea Youth Risk Behavior Web-based Survey (KYRBS). Ordinary least squares regression models were used to analyze the association between SHS exposure days and sleep duration, adjusting for individual, school, and family-level control variables. The moderating effect of tobacco use was examined through interaction terms.
RESULTS: SHS exposure demonstrated a significant negative association with adolescent sleep duration. After full adjustment for control variables, each additional day of SHS exposure was associated with a reduction in weekly average sleep duration (β= -0.027; 95% CI: -0.029 - -0.024, p<0.01), weekday sleep duration (β= -0.030; 95% CI: -0.03 - -0.028, p<0.01), and weekend sleep duration (β= -0.018; 95% CI: -0.023 - -0.013, p<0.01). Tobacco use significantly moderated this relationship, with the interaction term showing positive coefficients across all sleep duration models.
CONCLUSIONS: SHS exposure significantly associated with sleep deprivation among Korean adolescents, with this association being influenced by individual tobacco use habits.
