Little is known about the underlying factors that may explain the link between sedentary behavior and likelihood of depression. The purpose of this study was to investigate the contribution of selected intra-personal and social factors as potential mediators of the relationship between sedentary behavior and depressive symptoms among women from disadvantaged neighborhoods. Method: Cross-sectional survey data were provided by 4065 women (aged 18–45) living in disadvantaged neighborhoods. Women self-reported their sedentary behavior (total sitting time and screen time), depressive symptoms (CES-D 10), as well as a number of intra-personal (leisure-time physical activity, diet quality, weight status) and social (social cohesion, interpersonal trust, club membership) factors. Results: Mediating analyses, controlling for confounders, showed that women's leisure-time physical activity partly mediated the relationship between total sitting time and increased likelihood of depressive symptoms. Women's diet quality, and social cohesion partly mediated the relationship between screen time and increased likelihood of depressive symptoms. Conclusions: Acknowledging the cross-sectional study design, findings suggest that there may be several factors that explain the increased likelihood of depressive symptoms associated with greater sedentary time. Although future studies should test the mediating relationships longitudinally, these findings may help inform interventions aimed at reducing the likelihood of depression in disadvantaged women with high sitting time.
