Objective This study examines the impact of intergenerational economic support and related factors on the risk of disability among rural elderly,providing a decision-making reference for improving their health.Methods Using data from the 2018 China Health and Retirement Longitudinal Study(CHARLS),we focused on rural residents aged 60 and above with at least one child.A two-stage regression model with instrumental variables was constructed to analyze the factors affecting disability in the elderly.Results The number of disabled elderly was 1 384,accounting for 27.53％.Significant differences were found in the distribution of disabled population among different genders,ages,and chronic disease populations(P＜0.01).Intergenerational economic support can reduce the risk of disability in the elderly people(β＝-0.111,P＜0.01).The interaction effect analysis showed that the economic support received by males,older a-dults,and those with chronic diseases had a diminished effect on reducing the risk of disability(P＜0.01).Heterogenei-ty analysis results showed the effects of drinking alcohol,and having medical insurance on disability were only significant in the male sample(P＜0.05).Smoking status has a statistically significant impact only among the oldest-old groups(P＜0.05);Age,co-residence with children,number of children,and income significantly affect only the younger elderly groups(P＜0.05).Participation in medical insurance were significant only in the elderly with chronic diseases(P＜0.05),while smoking and income were significant only in the elderly people without chronic diseases(P＜0.05).Con-clusion The government should gradually increase economic support for rural elderly,encourage rural children to pro-vide economic support to their parents,enhance health education,and strengthen chronic disease prevention efforts to control morbidity rates.
