To understand the current situation, influencing factors, and urban-rural heterogeneity of overweight/obesity among the elderly in China, so as to provide basis for formulating corresponding intervention measures.
The data of people age ≥ 60 years old in China Family Panel Studies (CFPS) database in 2020 were used. Unconditional binary logistic regression was used to analyze the influencing factors of overweight/obesity in the elderly.
A total of 4 870 eligible samples were included in this study, of which 1 903 were overweight/obese, and the overweight/obesity rate was 39.08%(33.10% in rural areas and 36.56% in urban areas). People aged 60-69 (OR = 2.145, 95%CI: 1.559-2.951), 70-79 years old (OR = 1.752, 95%CI: 1.270-2.416), suffering from chronic diseases (OR = 1.215, 95%CI: 1.061-1.392), smoking (OR = 0.651,95%CI: 0.556-0.763), living in the central China (OR = 1.255, 95%CI: 1.052-1.498), eastern China (OR = 1.378, 95%CI:1.169-1.623), living in town (OR = 1.366, 95%CI: 1.193-1.565), with primary school education (OR = 1.214, 95%CI: 1.034-1.427), retirement pension (OR = 1.342, 95%CI: 1.126-1.599), and endowment insurance (OR = 0.841, 95%CI: 0.739-0.956) were the influencing factors of overweight/obesity in the elderly. People aged 60- 69 (OR = 2.333, 95%CI: 1.561-3.487), 70-79 years old (OR = 2.057, 95%CI: 1.372-3.084), suffering from chronic diseases (OR = 1.364, 95%CI: 1.132-1.645), smoking (OR = 0.705, 95%CI: 0.563-0.881), living in the eastern region (OR = 1.278, 95%CI: 1.006-1.623). with primary school education (OR = 1.397, 95%CI: 1.104-1.768), and retirement pension (OR = 1.284, 95%CI: 1.046-1.577) were the influencing factors of overweight/obesity of the urban elderly. People aged 60-69 years old (OR = 1.779, 95%CI: 1.048-3.021), smoking (OR =0.594, 95%CI: 0.473-0.747), living in central China (OR = 1.28, 95%CI: 1.010-1.647), eastern China (OR = 1.481, 95%CI:1.176-1.867), retirement pension (OR = 1.424, 95%CI: 1.003-2.022), and new rural cooperative medical system (NCMS) (OR =0.475, 95%CI: 0.261-0.862) and health insurance for urban/rural residents (OR = 0.615, 95%CI: 0.380-0.995) were the influencing factors of overweight/obesity of the rural elderly.
The influencing factors of overweight/obesity in the elderly are multi-level and multi-dimensional and vary between urban and rural areas. Timely and targeted preventive strategies and preventive measures should be taken from individual to macro dimensions, based on the current situation of urban-rural differences in China.
