Research regarding the protective effects of early physical activity on depression has yielded conflicting results.
Our objective was to synthesize observational studies examining the association of physical activity in childhood and adolescence with depression.
Studies (from 2005 to 2015) were identified by using a comprehensive search strategy.
The included studies measured physical activity in childhood or adolescence and examined its association with depression.
Data were extracted by 2 independent coders. Estimates were examined by using random-effects meta-analysis.
Fifty independent samples (89 894 participants) were included, and the mean effect size was significant ( = -0.14; 95% confidence interval [CI] = -0.19 to -0.10). Moderator analyses revealed stronger effect sizes in studies with cross-sectional versus longitudinal designs ( = 36, = -0.17; 95% CI = -0.23 to -0.10 vs = 14, = -0.07; 95% CI = -0.10 to -0.04); using depression self-report versus interview ( = 46, = -0.15; 95% CI = -0.20 to -0.10 vs = 4, = -0.05; 95% CI = -0.09 to -0.01); using validated versus nonvalidated physical activity measures ( = 29, = -0.18; 95% CI = -0.26 to -0.09 vs = 21, = -0.08; 95% CI = -0.11 to -0.05); and using measures of frequency and intensity of physical activity versus intensity alone ( = 27, = -0.17; 95% CI = -0.25 to -0.09 vs = 7, = -0.05; 95% CI = -0.09 to -0.01).
Limitations included a lack of standardized measures of physical activity; use of self-report of depression in majority of studies; and a small number of longitudinal studies.
Physical activity is associated with decreased concurrent depressive symptoms; the association with future depressive symptoms is weak.
有关早期体力活动对抑郁症的保护作用的研究结果相互矛盾。
我们的目的是综合观察性研究，考察儿童和青少年时期体力活动与抑郁症之间的关系。
研究（2005 年至 2015 年）是通过全面的搜索策略确定的。
纳入的研究测量了儿童或青少年时期的体力活动，并研究了其与抑郁症的关系。
由 2 名独立编码员提取数据。使用随机效应荟萃分析来检验估计值。
纳入了 50 个独立样本（89894 名参与者），平均效应量具有统计学意义（ = -0.14；95%置信区间[CI] = -0.19 至 -0.10）。 调节分析显示，横断面研究与纵向研究相比，效应量更大（ = 36， = -0.17；95%CI = -0.23 至 -0.10 与 = 14， = -0.07；95%CI = -0.10 至 -0.04）； 使用抑郁自评与访谈（ = 46， = -0.15；95%CI = -0.20 至 -0.10 与 = 4， = -0.05；95%CI = -0.09 至 -0.01）； 使用验证与非验证的体力活动测量（ = 29， = -0.18；95%CI = -0.26 至 -0.09 与 = 21， = -0.08；95%CI = -0.11 至 -0.05）； 使用频率和强度的体力活动测量与强度测量（ = 27， = -0.17；95%CI = -0.25 至 -0.09 与 = 7， = -0.05；95%CI = -0.09 至 -0.01）。
局限性包括缺乏标准化的体力活动测量； 大多数研究都使用抑郁的自我报告； 以及纵向研究数量较少。
体力活动与降低当前抑郁症状相关； 与未来抑郁症状的相关性较弱。
