摘要
Objectives: This paper aims to examine the relationship between obesity and onset of depression among U.S. middle-aged and older adults. Methods: Data came from 1994 to 2010 waves of the Health and Retirement Study. Study sample consisted of 6514 community-dwelling adults born between 1931 and 1941 who were free of clinically relevant depressive symptoms in 1994. Body mass index (BMI) was calculated from self-reported height/weight Body weight status was classified into normal weight (185 kg/m(2) <= BMI <25 kg/m(2)), overweight (25 kg/m(2) <= BMI <30 kg/m(2)), and obesity (BMI 30 kg/m2). A score of on the 8-item Center for Epidemiologic Studies Depression Scale was used to define clinically relevant depressive symptoms. Kaplan-Meier estimator and time-dependent Cox proportional hazards model were performed to examine the association between body weight status and onset of clinically relevant depressive symptoms. Results: Unhealthy body weight was associated future onset of depression. Compared with their normal weight counterparts, overweight and obese participants were 13% (hazard ratio [HR] = 1.13, 95% confidence interval [CI] = 1.04-1.23) and 9% (HR = 1.09,95% Cl = 1.01-1.18) more likely to have onset of clinically relevant depressive symptoms during the 16 years of follow-up, respectively. The relationship between obesity and depression onset appeared stronger among females and non-Hispanic whites than their male and racial/ethnic minority counterparts. Conclusions: Health care providers should be aware of the potential risk for depression among obese older adults. (C) 2014 Elsevier Inc. All rights reserved.
