... ng sociodemographic characteristics, LTPA behavior, self-reported health status, and self-evaluations (comprising height, body weight, and happiness). Results: By using multiple regression, after potential confounders adjustment, we observed that regular LTPA was significantly associated with happiness scores for men (β = 0.043, p = 0.001) and women (β = 0.050, p < 0.0001). Furthermore, multiple logistic regression results indicated that with the non-regular LTPA as a baseline, significant associations were observed both for men (odds ratio [OR] = 1.410, 95% CI: 1.173-1.693, p < 0.0001) and women (OR = 1.424, 95% CI: 1.169-1.735, p < 0.0001) at regular LTPA. Conclusions: The current study suggested that regular LTPA, potentially improve the occurrence of happiness among young men. Moreover, this positive effect of regular LTPA was observed for the occurrence of happiness in young women.
