Abstract

|
|
Purpose: The purpose of this study was to examine the association between physical activity (PA), leisure time sedentary behavior (LTSB), and self-rated health (SRH) in Korean adolescents.
Methods: A cross-sectional analysis was conducted on 53,510 Korean middle and high school students from the Korea youth risk behavior survey, 2020. Complex samples logistic regression was performed to examine the association between PA, LTSB, and SRH.
Results: Students with lower levels of PA were significantly greater odds of having ‘fair and (very) poor’ SRH than those with higher levels of PA (moderate PA, ≥ 60 minutes on ≥ 5 days/week; vigorous PA, ≥ 20 minutes on ≥ 3 days/week; and resistance exercise, ≥ 3 days/week). Students with >4 hours/day of LTSB were significantly greater odds of having ‘fair and (very) poor’ SRH than those with ≤ 2 hours/day of LTSB. Students with ‘fair and (very) poor’ SRH were significantly greater odds of having obesity than those with ‘(very) good’ SRH.
Conclusion: The results of this study showed that PA is positively associated with SRH, and LTSB (≤ 2 vs. > 4 hours/day) is negatively associated with SRH in Korean adolescents. SRH was negatively associated with obesity after adjusting the covariates including PA and LTSB.
