We examined the association between depressive symptoms and physical activity (PA) in a sample of men from the Aerobics Center Longitudinal Study. Secondary analysis included stratification by age and body mass index (BMI).
Our cross-sectional analysis included 9580 men, age 20-87 yr, who completed the 10-item Center for Epidemiological Studies Depression Scale during 1996-2006. A score of 10 or higher defined depressive symptoms. Four PA categories based on the 2008 PA guidelines were created from a self-report leisure time PA questionnaire: inactive (0 MET·min·wk(-1)), low (1-499 MET·min·wk(-1)), medium (500-999 MET·min·wk(-1)), and high (≥1000 MET·min·wk(-1)).
There were 727 men with depressive symptoms. Cross-sectional analyses showed a significant inverse relationship between PA categories and depressive symptoms (P for trend < 0.0001). This reduction in odds was shown across all types of measured leisure time activities (odds ratios = 0.36-0.58). Compared with the inactive group, the light, medium, and high PA categories were 24%, 51%, and 51% less likely to exhibit depressive symptoms, respectively. The inverse relationship was maintained for age and BMI groups except for those 60 yr or older, who exhibited fewer depressive symptoms than other ages. Men with a BMI of 30 kg·m(-2) or higher lowered their odds of depressive symptoms for all PA categories, whereas those with a BMI less than 30 kg·m(-2) needed at least 500 MET·min·wk(-1) to show a similar association.
Overall, our analyses found an inverse association between PA and depressive symptoms. Most of this benefit was seen in the medium PA category, which seemed to plateau around 500 MET·min·wk(-1). This indicates that men meeting the 2008 PA Guidelines may not only experience physical health benefits but also reduce the likelihood of depressive symptoms.
我们在一项男性纵向研究中，检查了抑郁症状与身体活动（PA）之间的关联。二次分析按年龄和体重指数（BMI）进行分层。
我们的横断面分析包括 1996-2006 年期间完成了 10 项中心流行病学研究抑郁量表的 9580 名 20-87 岁男性。得分 10 或更高定义为抑郁症状。根据 2008 年 PA 指南，从自我报告的休闲时间 PA 问卷中创建了四个基于 PA 类别的分类：不活跃（0 MET·min·wk(-1)），低（1-499 MET·min·wk(-1)），中（500-999 MET·min·wk(-1)）和高（≥1000 MET·min·wk(-1)）。
有 727 名男性患有抑郁症状。横断面分析显示，PA 类别与抑郁症状之间存在显著的反比关系（P 趋势<0.0001）。这种降低的可能性在所有类型的测量休闲时间活动中均可见（比值比=0.36-0.58）。与不活跃组相比，轻、中、高 PA 类别分别有 24%、51%和 51%的可能性出现抑郁症状。除 60 岁及以上的人群外，这种反比关系在年龄和 BMI 组中均得到维持，这些人群的抑郁症状比其他年龄段少。BMI 为 30 kg·m(-2)或更高的男性，所有 PA 类别降低了抑郁症状的可能性，而 BMI 低于 30 kg·m(-2)的男性则需要至少 500 MET·min·wk(-1)才能显示出类似的关联。
总体而言，我们的分析发现 PA 与抑郁症状之间存在反比关系。这种益处主要见于中等 PA 类别，该类别似乎在 500 MET·min·wk(-1)左右达到平台期。这表明，符合 2008 年 PA 指南的男性不仅可能获得身体健康益处，而且还可能降低抑郁症状的可能性。
