Abstract

Statement of problem: Associations between sedentary behavior (e.g. time spent sitting watching TV/using the computer) and physical health have been well documented, however, studies are increasinglyreporting a positive relationship between certain sedentary behaviors and poor mental health (e.g.depression). Little is known about the underlying factors that may explain the link between sedentarybehavior and likelihood of depression. The purpose of this study was to investigate the contribution ofselected intra-personal and social factors as potential mediators of the relationship between sedentarybehavior and depressive symptoms among women from disadvantaged neighborhoods.Method: Cross-sectional survey data were provided by 4065 women (aged 18e45) living in disadvan-taged 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 physicalactivity partly mediated the relationship between total sitting time and increased likelihood ofdepressive symptoms. Women’s diet quality, and social cohesion partly mediated the relationship be-tween screen time and increased likelihood of depressive symptoms.Conclusions: Acknowledging the cross-sectional study design, findings suggest that there may be severalfactors that explain the increased likelihood of depressive symptoms associated with greater sedentarytime. Although future studies should test the mediating relationships longitudinally, these findings mayhelp inform interventions aimed at reducing the likelihood of depression in disadvantaged women withhigh sitting time. 2013 Elsevier Ltd.
