Abstract

This study aimed to identify heterogeneous physical activity patterns among adolescents and examine their associations with social characteristics (N=793). Latent Profile Analysis (LPA) was conducted using vigorous-intensity activity, moderate-intensity activity, and walking as indicators. A six-profile solution was identified: combined moderate- and vigorous-intensity activity (27.6%), walking-oriented low-activity (24.3%), overall high-activity (23.5%), moderate-intensity activity-oriented (12.1%), vigorous-intensity activity-oriented (7.9%), and overall low-activity (4.6%). A three-step approach (R3STEP) accounting for classification error was applied to examine associations with sex, household economic status, private academy attendance, and parental exercise participation. Omnibus Wald tests revealed significant overall differentiation by sex (p<.001) and parental exercise participation (p=.030), whereas household economic status and academy attendance were not significant. Specifically, compared with boys, girls had significantly higher odds of belonging to low- and moderate-intensity profiles relative to the overall high-activity profile. Higher parental exercise participation was associated with increased odds of belonging to the overall high-activity profile rather than the walking-oriented low-activity or combined moderate- and vigorous-intensity profiles.
