Age-Friendly Cities and the Incidence of Diagnosed Diabetes in China: Evidence from the 2018–2020 China Health and Retirement Longitudinal Studies
摘要
Urbanization intensifies aging challenges, positioning cities to address non-communicable diseases like diabetes through age-friendly planning, policies, and health interventions. This study used data from the 2018–2020 CHARLS, along with city characteristics from the China City Statistical Yearbook and Google Earth Engine. Principal component analysis and the entropy method were employed to construct a comprehensive picture of age-friendliness, encompassing five domains: health service and social security, housing conditions, community atmosphere, economic development, and ecological environment. Multilevel logistic regression models were then applied to analyze the relationship between age-friendly environments and the incidence of diabetes among older adults in China. The results indicate that a higher level of community atmosphere was associated with a lower risk of developing diagnosed diabetes within two years. The findings highlight the need to enhance home and community services, integrate smart technologies, and diversify elderly care solutions to mitigate diabetes risk among older adults.
