This research aims to understand the complex relationships between various factors and diabetes prevalence in middle-aged and older adults in China.
Utilized longitudinal data from the China Health and Retirement Longitudinal Study (CHARLS, 2011–2020)
Developed a framework to analyze spatiotemporal dynamics of diabetes prevalence
Conducted spatial autocorrelation analysis to identify clustering patterns
Applied Random Forest–SHAP approach to quantify contributions of various drivers
Diabetes prevalence showed a rise-then-decline pattern, peaking in 2018
Significant spatial clustering identified, with northeast and central-eastern China as hotspots
Body mass index (BMI) emerged as the most influential driver, with significant effects once exceeding 24 kg/m²
Ecosystem quality displayed an inverse relationship with diabetes prevalence, providing protective effects within a specific range
