Associations of child sexual and physical abuse with obesity and depression in middle-aged women

Abstract

Objective: Examine whether (1) childhood maltreatment is associated with subsequent obesity and depression in middle-age; (2) maltreatment explains the associations between obesity and depression; and (3) binge eating or body dissatisfaction mediate associations between childhood maltreatment and subsequent obesity.

Methods: Data were obtained through a population-based survey of 4641 women (mean age=52 years) enrolled in a large health plan in the Pacific Northwest. A telephone survey assessed child sexual and physical abuse, obesity (BMI>or=30), depressive symptoms, binge eating, and body dissatisfaction. Data were analyzed using logistic regression models incorporating sampling weights.

Results: Both child sexual and physical abuse were associated with a doubling of the odds of both obesity and depression, although child physical abuse was not associated with depression for the African American/Hispanic/American Indian subgroup. The association between obesity and depression (unadjusted OR=2.82; 95% CI=2.20-3.62) was reduced somewhat after controlling for sexual abuse (adjusted OR=2.54; 1.96-3.29) and for physical abuse (adjusted OR=2.63; 2.03-3.42). Controlling for potential mediators failed to substantially attenuate associations between childhood maltreatment and obesity.

Conclusions: This study is the first to our knowledge that compares associations of child abuse with both depression and obesity in adults. Although the study is limited by its cross-sectional design and brief assessments, the fact that child abuse predicted two debilitating conditions in middle-aged women indicates the potential long-term consequences of these experiences.
