Abstract

Abstract

Objective To examine the association between BMI and the incidence of disability assessed by instrumental activities of daily living (IADL) among middle-aged and older Chinese. Methods This study was based on the China health and retirement longitudinal study 2011-2015 (baseline to second follow-up visits). After excluding participants with IADL-defined disability at baseline, 8 955 participants were included in the study. Binary Logistic liner regression model was performed to determine the association bewteen BMI and incidence of IADL-defined disability. Results During 4 years of follow-up, 2 186 (24.41%) participants developed disability (18.79% in men and 29.89% in women). The incidence rates of disability were 42.64%, 25.13%, 19.85% and 23.49% in the underweight, normal weight, overweight and obesity groups, respectively. Compared with participants with normal weight, the adjusted odds ratio of disability in participants who were underweight, overweight and obese were 1.381 (95% CI: 1.117-1.707, P=0.003)、0.830 (95% CI: 0.727-0.948, P=0.006) and 0.985 (95% CI: 0.819-1.185, P=0.874), respectively. Conclusions Compared with participants with normal weight, underweight was positively associated with risk of disability, and there was an inverse association between overweight and disability, while no significant association was observed between obesity and disability.
