Abstract
OBJECTIVE
We examine the mediating role of body image dissatisfaction (BID) on the association between obesity and depression and the variation of this association as a function of years of education among a population-based sample of women aged 40-65 years.
METHODS
A series of sample-weighted logistic regression models were used to estimate the associations between obesity, BID, and depression, stratified by educational attainment. Data were obtained from a structured telephone interview of 4543 female health plan enrollees, including self-reported height and weight, the Patient Health Questionnaire assessment of depression, and a single-item measure of BID.
RESULTS
Among those with <16 years of education, in both the unadjusted and adjusted models, obesity and BID were significantly associated with depression. Similarly, among those with ≥ 16 years of education, obesity and BID were significantly associated with depression in the unadjusted models. However, in the adjusted model, only BID was associated with depression. A formal test for mediation suggests that the association between obesity and depression was mediated by BID regardless of level of education.
CONCLUSIONS
Our data suggest that BID-mediated the obesity-depression association. In addition, obesity and BID may be salient risk factors for depression among middle-aged women as a function of the level of education.
