Our aim was to analyze the association between different social contexts of physical activity (PA) and depressive symptoms. Data from the Brazilian National Health Survey (PNS) (n = 59,722; ≥18 years) were used. The social context of leisure-time PA [classified according to the higher probability of being practiced in group (group PA) or individually (individual PA)] and total PA time were self-reported. Depressive symptoms were evaluated through the Patient Health Questionnaire-9. Chronological age, ethnicity, educational status, employment status, tobacco smoking, alcohol ingestion, and soft drink consumption were co-variables. Logistic regression models were applied for association analyses. Among men, individual and group PA were associated with lower depressive symptoms compared with the no PA group among men [Individual: OR:0.59 (95%CI:0.40 to 0.86); Group: OR:0.42 (95%CI:0.29 to 0.59)]. Sensitivity analysis revealed that men involved in group PA were 40% [OR:0.60 (95%CI:0.38 to 0.94)] less likely to present elevated depressive symptoms when compared with individual PA. In females, no differences in depressive symptoms were observed comparing individual PA [OR:0.89 (95%CI:0.71 to 1.11)] and group PA [OR:0.86 (95%CI:0.54 to 1.37)] with the no PA group. Activities that are more likely to be a group PA demonstrated a stronger association with low depressive symptoms among men, but not women.

我们的目的是分析体育活动（PA）的不同社会环境与抑郁症状之间的关联。使用了来自巴西国家健康调查（PNS）的数据（n = 59,722；≥18岁）。闲暇时间PA的社会情境[根据在小组中（组PA）或个人（个人PA）中被实践的较高概率进行分类）和总的PA时间是自我报告的。通过患者健康问卷9评估抑郁症状。年代，年龄，种族，受教育程度，就业状况，吸烟，饮酒和喝软饮料是协变量。Logistic回归模型用于关联分析。在男性中，与无PA组相比，男性和个人PA与较低的抑郁症状相关[个人：OR：0.59（95％CI：0。40至0.86）；组：OR：0.42（95％CI：0.29至0.59）。敏感性分析显示，与单独的PA相比，参与PA组的男性出现抑郁症状的可能性要低40％[OR：0.60（95％CI：0.38至0.94）]。在女性中，与单独的PA [OR：0.89（95％CI：0.71至1.11）]和PA组[OR：0.86（95％CI：0.54至1.37）]和无PA组相比，抑郁症状没有差异。在男性而非女性中，更有可能是PA行为的活动表现出与低抑郁症状的相关性更强。与单独的PA [OR：0.89（95％CI：0.71至1.11）]和PA组[OR：0.86（95％CI：0.54至1.37）]与无PA组进行比较，没有观察到抑郁症状的差异。在男性而非女性中，更有可能是PA行为的活动表现出与低抑郁症状的相关性更强。与单独的PA [OR：0.89（95％CI：0.71至1.11）]和PA组[OR：0.86（95％CI：0.54至1.37）]与无PA组进行比较，没有观察到抑郁症状的差异。在男性而非女性中，更有可能是PA行为的活动表现出与低抑郁症状的相关性更强。
