Physical Environment May Modify the Association Between Depressive Symptoms and Change in Waist Circumference: The Multi-Ethnic Study of Atherosclerosis

BACKGROUND: Although the bidirectional association between depressive symptoms and adiposity has been recognized, the contribution of neighborhood factors to this relationship has not been assessed. This study evaluates whether physical and social neighborhood environment modify the bidirectional relationship between depressive symptoms and adiposity (measured by waist circumference and BMI). METHODS: Using data on 5,122 men and women (age 45-84 years) from the Multi-Ethnic Study of Atherosclerosis (MESA) we investigated whether neighborhood physical (i.e. walking environment, availability of healthy food) and social (i.e. safety, aesthetics, social coherence) environments modified the association between: (1) baseline elevated depressive symptoms (EDS, Center for Epidemiologic Study Depression Scale score ≥ 16) and change in adiposity (as measured by waist circumference [WC] and body mass index [BMI]); and (2) baseline overweight/obesity (WC > 102 cm for men and > 88 cm for women, or BMI ≥ 25 kg/m(2)) and change in depressive symptoms using multilevel models. Neighborhood-level factors were obtained from the MESA Neighborhood Study. RESULTS: A greater increase in WC in participants with versus without EDS was observed in those living in poorly-rated physical environment, but not in those living in better-rated environments (interaction p-value=0.045). No associations were observed with BMI. Baseline overweight/obesity was not associated with change in depressive symptoms and there was no modification by neighborhood-level factors. CONCLUSIONS: EDS were associated with greater increase in WC among individuals living in poor than in better-rated physical environments. No association was found between overweight/obesity and change in depressive symptoms
