Lower social participation and less frequent walking represent two factors that may contribute to depression among older adults, but previous research on the subject is inconclusive. The aim of this cross-sectional study was to quantify associations between depression and the combined effects from social participation and walking in a sample of older adults living in Canada (n = 549). Linear and logistic regression analyses were conducted, in which we entered social participation and walking as predictors of depression while controlling for individual characteristics. Results of the final models show that individuals who do not walk outside their home report more depressive symptoms or a greater likelihood of possible clinical depression (the association in our study between social participation and depression was attenuated to non-significance). The current study highlights the central role played by life habits, such as walking, in older adults' mental health status.
较低的社会参与度和较少的步行频率是导致老年人抑郁的两个因素，但之前关于这一主题的研究结果并不一致。本横断面研究的目的是在加拿大的老年人群体中（n=549），定量评估抑郁与社会参与和步行综合效应之间的关联。我们进行了线性和逻辑回归分析，在控制个体特征的同时，将社会参与和步行作为抑郁的预测因子。最终模型的结果表明，那些不走出家门散步的人报告的抑郁症状更多或更有可能患有临床抑郁症（本研究中社会参与与抑郁之间的关联减弱至无显著性）。本研究强调了生活习惯（如散步）在老年人心理健康状况中的核心作用。
