Given its high prevalence and impact on quality of life, more research is needed in identifying factors that may prevent depression. This review examined whether physical activity (PA) is protective against the onset of depression.
A comprehensive search was conducted up until December 2012 in the following databases: MEDLINE, Embase, PubMed, PsycINFO, SPORTDiscus, and Cochrane Database of Systematic Reviews. Data were analyzed between July 2012 and February 2013. Articles were chosen for the review if the study used a prospective-based, longitudinal design and examined relationships between PA and depression over at least two time intervals. A formal quality assessment for each study also was conducted independently by the two reviewers.
The initial search yielded a total of 6363 citations. After a thorough selection process, 30 studies were included for analyses. Among these, 25 studies demonstrated that baseline PA was negatively associated with a risk of subsequent depression. The majority of these studies were of high methodologic quality, providing consistent evidence that PA may prevent future depression. There is promising evidence that any level of PA, including low levels (e.g., walking <150 minutes/weeks), can prevent future depression.
From a population health perspective, promoting PA may serve as a valuable mental health promotion strategy in reducing the risk of developing depression.
鉴于其高患病率和对生活质量的影响，需要更多的研究来确定可能预防抑郁的因素。本综述研究了体育活动（PA）是否能预防抑郁的发生。
截至 2012 年 12 月，在以下数据库中进行了全面检索：MEDLINE、Embase、PubMed、PsycINFO、SPORTDiscus 和 Cochrane 系统评价数据库。2012 年 7 月至 2013 年 2 月分析数据。如果研究使用前瞻性、纵向设计，并在至少两个时间间隔内检查 PA 与抑郁之间的关系，则选择文章进行综述。两位评审员还独立对每项研究进行了正式的质量评估。
最初的搜索共产生了 6363 条引文。经过彻底的选择过程，有 30 项研究被纳入分析。其中，25 项研究表明，基线 PA 与随后发生抑郁的风险呈负相关。这些研究大多具有较高的方法学质量，提供了一致的证据表明 PA 可能预防未来的抑郁。有有希望的证据表明，任何水平的 PA，包括低水平（例如，步行 <150 分钟/周），都可以预防未来的抑郁。
从人群健康的角度来看，促进 PA 可能是一种有价值的心理健康促进策略，可降低患抑郁的风险。
