Abstract: Objective To investigate the prevalence and distribution characteristics of body weight status among people aged ≥60 years old in Nanjing, China. Methods In this cross-sectional study, 20 883 regular residents aged ≥60 years were enrolled using a multistage stratified sampling approach from April to October 2017 in Nanjing. The demographic information and anthropometric characteristics were collected. The body weight status was defined and categorized as underweight [body mass index (BMI)<18.5], normal weight(18.5≤BMI<24), overweight(24≤BMI<28) and obesity(BMI≥28). The distribution characteristics of body weight were analyzed. Results The mean BMI of the elderly population in Nanjing was 24.4±3.3, while 2.5% of the participants presented with underweight, 44.4% with normal weight, 40.0% with overweight, and 13.1% with obesity. The overweight rate was significantly higher in men(41.0%) than that in women(39.1%), but the obesity rate(11.3%) was lower than that in women(14.8%). The underweight rate in the elderly population tended to increase with age, while the overweight rate tended to decrease with age (P<0.05). The obesity rate significantly decreased with the increase of the educational level among the participants (P<0.05). Conclusions The elderly show a low rate of underweight and a high rate of overweight and obesity in Nanjing, China. Tailored precision intervention strategies on healthy weight campaigns with participants’ characteristics are crucial for public health in China.
