This study aimed to examine the association between physical activity (PA) and subjective well-being (SWB) in Chinese college students, and to determine if the perceived health mediated this association, while both controlling for age, gender, and body mass index (BMI).
1204 college students (47.8% female, mean age =19.76 ± 1.29 years) voluntarily completed a set of questionnaires in a single-wave (cross-sectional) assessment in 2016.
Participants answered questions measuring happiness, life satisfaction, PA, and perceived health. Five multiple regression models were performed to test the mediating effect. Age, gender, and body weight status were added to all models as covariates.
Meeting the moderate- to vigorous-PA (MVPA) guideline (>150 min/week) was associated with higher levels of happiness and life satisfaction ('s < 0.001). These positive associations were weakened while controlling for the perceived health. Gender was a significant covariate for happiness and body weight status was a significant covariate for life satisfaction. Age was not a significant covariate for all models.
PA is positively associated with SWB among college students and this positive association is partially mediated by the individual levels of perceived health. Universities might consider providing exercise programs and advocating students participating more MVPA as effective ways to support students' mental and emotional well-being.
本研究旨在探讨中国大学生身体活动（PA）与主观幸福感（SWB）之间的关系，并确定在控制年龄、性别和体重指数（BMI）的情况下，感知健康是否中介了这种关联。
1204 名大学生（47.8%为女性，平均年龄=19.76±1.29 岁）于 2016 年在单次（横断面）评估中自愿完成了一组问卷。
参与者回答了关于幸福感、生活满意度、PA 和感知健康的问题。进行了五个多元回归模型来检验中介效应。年龄、性别和体重状况被添加到所有模型中作为协变量。
达到中等到剧烈身体活动（MVPA）指南（>150 分钟/周）与更高水平的幸福感和生活满意度相关（s<0.001）。在控制感知健康后，这些积极关联减弱。性别是幸福感的一个重要协变量，体重状况是生活满意度的一个重要协变量。年龄对所有模型均不是重要的协变量。
PA 与大学生的 SWB 呈正相关，这种积极的关联部分由个体感知健康水平所中介。大学可以考虑提供锻炼计划并倡导学生更多地参与中到剧烈身体活动，这是支持学生心理和情感健康的有效途径。
