Lifestyle behaviors such as healthy diet and some forms of physical activity have been linked to lower risk of depressive symptoms in the general population. However, little is known regarding their associations with postnatal depressive symptoms. Given that postnatal women (particularly those living in socioeconomically disadvantaged neighborhoods) are more likely to have poorer diet quality, lower physical activity levels and greater risk of depressive symptoms, this study sought to determine the associations between diet quality, total and domain specific physical activity and depressive symptoms amongst postnatal women from socioeconomically disadvantaged neighborhoods. It was hypothesized that higher diet quality and levels of leisure-time physical activity would be associated with lower depressive symptoms. In 2007-2008, cross-sectional data were collected from 246 women living in socioeconomically disadvantaged neighborhoods in Victoria, Australia. Participants completed self-report measures of diet (using a 17 item dietary questionnaire), domain specific physical activity (International Physical Activity Questionnaire), and depressive symptoms (Centre for Epidemiologic Studies Depression Scale). Linear regression analyses were used to determine the associations between diet quality, physical activity and postnatal depressive symptoms. There was a significant inverse association between total physical activity (B, -0.009; 95% CI, -0.016 to -0.001; P = .023) and postnatal depressive symptoms. No association was found between other domain-specific physical activity (i.e. leisure-time, domestic or transport-related physical activity), or diet quality and postnatal depressive symptoms. Acknowledging the cross-sectional nature of this study, these findings suggest that total physical activity may play a more important role than diet quality in the relationship with postnatal depressive symptoms.
生活方式行为，如健康饮食和某些形式的体育活动，与一般人群中抑郁症状的风险降低有关。然而，对于它们与产后抑郁症状的关系知之甚少。鉴于产后妇女（尤其是那些生活在社会经济处于不利地位的社区的妇女）更有可能饮食质量较差、体育活动水平较低和抑郁症状风险较高，本研究旨在确定社会经济处于不利地位的社区中产后妇女的饮食质量、总体和特定领域体育活动与抑郁症状之间的关系。研究假设，较高的饮食质量和休闲时间体育活动水平与较低的抑郁症状有关。2007-2008 年，在澳大利亚维多利亚州社会经济处于不利地位的社区中，对 246 名妇女进行了横断面数据收集。参与者完成了自我报告的饮食测量（使用 17 项饮食问卷）、特定领域的体育活动（国际体力活动问卷）和产后抑郁症状（流行病学研究抑郁量表）。线性回归分析用于确定饮食质量、体育活动与产后抑郁症状之间的关系。总体育活动（B，-0.009；95%置信区间，-0.016 至-0.001；P=0.023）与产后抑郁症状之间存在显著负相关。其他特定领域的体育活动（即休闲时间、家庭或交通相关的体育活动）或饮食质量与产后抑郁症状之间没有关联。鉴于本研究的横断面性质，这些发现表明，总体育活动可能比饮食质量在与产后抑郁症状的关系中发挥更重要的作用。
