We assessed the relationship between physical activity (PA) and mental health among Chinese adolescents. We conducted a cross-sectional survey in 4 Chinese cities - Beijing, Shanghai, Nanchang, and Urumchi. We randomly selected 25 schools from these cities in both urban and suburban areas. A total of 9269 adolescents completed the survey. We conducted multilevel logistic regressions to examine the relationship between PA engagement and mental health, adjusting for various sample characteristics. Compared to those with low levels of daily PA, adolescents with moderate and high levels of daily PA had lower odds of having learning anxiety (23% for moderate and 37% for high), solitude tendency (52% for moderate and 41% for high), self-accusation (13% for moderate and 15% for high), experiencing sensitivity (15% for moderate and 13% for high), physical symptoms (20% for moderate and 21% for high), and a general mental health problem (total score of all the domains: 41% and 34%). An increase in PA participation holds the potential to improve multiple mental health domains among Chinese adolescents. Future longitudinal or experimental research is warranted to confirm findings from this study.
我们评估了身体活动（PA）与中国青少年心理健康之间的关系。我们在中国的 4 个城市（北京、上海、南昌和乌鲁木齐）进行了一项横断面调查。我们从这些城市的城市和郊区随机选择了 25 所学校。共有 9269 名青少年完成了调查。我们进行了多层次逻辑回归分析，以检验 PA 参与与心理健康之间的关系，同时调整了各种样本特征。与每天低水平 PA 的青少年相比，每天进行中等到高水平 PA 的青少年出现学习焦虑（中等到高水平分别为 23%和 37%）、孤独倾向（中等到高水平分别为 52%和 41%）、自责（中等到高水平分别为 13%和 15%）、易感性（中等到高水平分别为 15%和 13%）、身体症状（中等到高水平分别为 20%和 21%）和一般心理健康问题（所有领域的总分：41%和 34%）的几率较低。增加 PA 参与有可能改善中国青少年的多个心理健康领域。未来需要进行纵向或实验研究来证实本研究的结果。
