Abstract
OBJECTIVETo determine whether the relationship between age and physical and mental health varies by diabetes status in older U.S. adults.RESEARCH DESIGN AND METHODSUsing data from the National Social Life, Health, and Aging Project, a national sample of 3,005 adults aged 57-85 years, we tested the significance of the interaction between age and diabetes in association with health states.RESULTSRespondents with diabetes in the youngest age cohort had more medical conditions than those without diabetes, a difference that narrowed with age (P for interaction <0.01). The youngest cohort with diabetes had a higher rate of depression compared to those without diabetes (14 vs. 8%). Depression declined with age and did not differ by diabetes status in the oldest respondents (P = 0.01 for age-diabetes interaction).CONCLUSIONSDiabetes differentially affects self-rated overall health and depression by age, with convergence in the oldest age-group with and without diabetes.
