This study aimed to investigate the bi-directional relationship between different domains of physical activity (PA), sedentary behaviour (SB) and depressive symptoms among women living in socioeconomically disadvantaged neighbourhoods in Victoria, Australia. Women (n=1033), aged 18-46years at Wave 1 (2007/08), completed self-report measures of PA (leisure-time, transport, occupational, domestic), SB (TV viewing, computer use, overall sitting time) and depressive symptoms (CES-D 10) at each study time-point (Wave 2: 2010/11, Wave 3: 2012/13). Separate linear mixed models were fitted to examine if change in depressive symptoms differed dependent on each of the baseline PA or SB measures. Similarly, baseline depressive symptoms were used as a predictor of change in PA and SB. In secondary analyses, associations between baseline PA or SB and odds of becoming 'at risk' of depression among those not 'at risk' at baseline were examined using logistic regression. There was no evidence that change in depressive symptoms differed depending on PA or SB at baseline. In general, there was also no evidence that change in PA or SB differed depending on baseline depressive symptoms. One exception was change in leisure-time PA, which declined more among those with heightened depressive symptoms at baseline (Interaction: β=-0.003, 95% CI=-0.007, -0.0003). Transport-related PA (adjusted OR=1.06, 95% CI=1.013, 1.101) and domestic PA (adjusted OR=1.02, 95% CI=1.003, 1.040) were associated with greater odds of becoming at risk of depression at wave 3. There was limited evidence of a bi-directional relationship between PA, SB and depressive symptoms in women living in socioeconomically disadvantaged neighbourhoods.
本研究旨在调查在澳大利亚维多利亚州社会经济地位处于劣势的社区中生活的女性中，不同领域的身体活动（PA）、久坐行为（SB）和抑郁症状之间的双向关系。女性（n=1033）在第 1 波（2007/08 年）时年龄为 18-46 岁，在每个研究时间点（第 2 波：2010/11 年，第 3 波：2012/13 年）完成了 PA（休闲时间、交通、职业、家务）、SB（电视观看、电脑使用、总坐姿时间）和抑郁症状（CES-D 10）的自我报告测量。分别使用线性混合模型来检查基线 PA 或 SB 测量值的变化是否取决于抑郁症状的变化。同样，使用基线抑郁症状作为 PA 和 SB 变化的预测因子。在次要分析中，使用逻辑回归检验基线 PA 或 SB 与基线时没有“处于危险”的人群中“处于危险”的可能性之间的关联。没有证据表明抑郁症状的变化取决于基线时的 PA 或 SB。一般来说，也没有证据表明 PA 或 SB 的变化取决于基线时的抑郁症状。一个例外是休闲时间 PA 的变化，基线时抑郁症状加重的人群中，该值下降更多（交互作用：β=-0.003，95%CI=-0.007，-0.0003）。与交通相关的 PA（调整后的 OR=1.06，95%CI=1.013，1.101）和家务 PA（调整后的 OR=1.02，95%CI=1.003，1.040）与第 3 波时处于抑郁风险的可能性增加相关。在社会经济地位处于劣势的社区中生活的女性中，PA、SB 和抑郁症状之间存在双向关系的证据有限。
