Ischemic heart disease leads the recent decline in healthy life expectancy in China.
Ischemic heart disease remains the leading contributor to the decline in healthy life expectancy among older adults in China, highlighting the need for integrated chronic disease prevention.
IHD may drive HLE losses among older Chinese adults; extends observational consensus but remains hypothesis-generating without causal confirmation.
Objectives: This study aimed to quantify the impact of major chronic diseases on changes in healthy life expectancy (HLE) from 2011 to 2020 in China using an age-specific disability weights (DW) estimation method. Methods: were decomposed into mortality and disability effects by cause, based on the estimated DWs. Results: were associated with disability from arthritis. Conclusion: in China improved from 2011 to 2020 and IHD remained the leading contributor to its decline, particularly through increased mortality. Disabilities related to diabetes, stroke, and arthritis had significant negative impacts. These findings highlight the need to strengthen integrated chronic disease prevention and rehabilitation services at community health centers.
