Secondary analysis of four surveys was carried out in order to examine the association of physical activity and various aspects of mental health in the household populations of the United States and Canada. Level of physical activity was shown to be positively associated with general well-being, lower levels of anxiety and depression, and positive mood. This relationship is independent of the effects of socioeconomic status and physical health, and described younger and older members of both sexes. The association is particularly strong for women and persons age 40 years and over. The robustness of this conclusion stems from the nature of the data sources: four population samples in two countries over the span of 10 years in which physical activity levels were assessed by four techniques and psychological status was assessed by six distinct scales. Although the surveys are cross-sectional, the most plausible explanation for the results is that physical activity enhances mental health in certain respects. Data on the comparative effects of recreation and housework suggest that quality of time, and not mere energy expenditure, must be taken into account in attempts to explain the psychological benefits of physical activity.
为了研究美国和加拿大家庭人口的身体活动与心理健康各方面之间的关联，对四项调查进行了二次分析。结果显示，身体活动水平与总体幸福感、较低的焦虑和抑郁水平以及积极情绪呈正相关。这种关系独立于社会经济地位和身体健康的影响，涵盖了男女老少。这种关联在女性以及40岁及以上人群中尤为强烈。这一结论的可靠性源于数据来源的性质：来自两个国家的四个总体样本，跨越10年，其中身体活动水平通过四种技术进行评估，心理状态通过六种不同量表进行评估。尽管这些调查是横断面研究，但对结果最合理的解释是身体活动在某些方面能促进心理健康。关于娱乐活动和家务劳动比较效果的数据表明，在试图解释身体活动对心理的益处时，必须考虑时间质量，而不仅仅是能量消耗。
