Depression is becoming a common threat to the mental health of Chinese adolescents. As an intermediate stage between being healthy and having depression, identifying factors influencing depressive may contribute to providing more options for the prevention and treatment of depression.
The study aims to explore the effects of physical activity on adolescent depression, focusing on the times and hours of activity per week.
The study used a cross-sectional dataset collected in Ruyang County, Henan Province in September 2022, including a sample of 5,629 adolescents in 31 compulsory public schools in the county. We utilized Ordinary Least Squares (OLS) to analyze the impact of physical activity on adolescents' depression scores, and probit model to analyze the influence of physical activity on adolescents' depression. To examine whether there is a U-shaped relationship between physical activity and depression, we included the squared terms of times and hours of activity in models.
The results showed that: (1) The times of physical activity significantly reduces Chinese adolescent depression. An increase in physical activity by one time per week is associated with a mean decrease of 0.354 points in depression scores ( < 0.01). However, an increase of one time of physical activity per week is associated with an average 1% increase in the likelihood of experiencing depression( < 0.05), while the hours of physical activity was statistically insignificant. (2) Physical activity has a U-shaped (not linear) relationship with adolescent depression, with 7-8 times per week or 7-9 h of physical activity per week being the optimal range.
The study found that increasing the frequency of physical activity positively impacts adolescent depression, while increasing the hours does not show a significant association. Furthermore, a U-shaped relationship exists between times of activity, hours of activity, and adolescent depression, suggesting that moderate activity is optimal.
抑郁症正成为中国青少年心理健康的常见威胁。作为健康与抑郁之间的中间阶段，识别影响抑郁的因素可能有助于为抑郁症的预防和治疗提供更多选择。
本研究旨在探讨体育活动对青少年抑郁症的影响，重点关注每周的活动次数和时长。
本研究使用了2022年9月在河南省汝阳县收集的横断面数据集，包括该县31所公立义务教育学校的5629名青少年样本。我们使用普通最小二乘法（OLS）分析体育活动对青少年抑郁得分的影响，并使用概率模型分析体育活动对青少年抑郁的影响。为了检验体育活动与抑郁之间是否存在U型关系，我们在模型中纳入了活动次数和时长的平方项。
结果表明：（1）体育活动次数显著降低中国青少年的抑郁水平。每周体育活动次数增加一次，抑郁得分平均降低0.354分（<0.01）。然而，每周体育活动次数增加一次，患抑郁症的可能性平均增加1%（<0.05），而体育活动时长在统计学上不显著。（2）体育活动与青少年抑郁呈U型（非线性）关系，每周7 - 8次或每周7 - 9小时的体育活动为最佳范围。
研究发现，增加体育活动频率对青少年抑郁有积极影响，而增加时长则未显示出显著关联。此外，活动次数、活动时长与青少年抑郁之间存在U型关系，表明适度活动是最佳的。
