Long-term exposure to ambient air pollution and cardiometabolic multimorbidity in Chinese adults over 45 years.

ABSTRACT: The rising prevalence of cardiometabolic multimorbidity (CMM), characterized by the coexistence of two or more cardiometabolic disorders, poses a significant public health challenge in aging populations. While ambient air pollution is a recognized environmental risk factor, its long-term impact on CMM remains underexplored, particularly in China. Utilizing data from the China Health and Retirement Longitudinal Study (CHARLS, 2015 wave), we analyzed 9,830 participants aged ≥ 45 years. CMM was defined as the concurrent presence of two or more conditions: diabetes/hyperglycemia, cardiovascular diseases (myocardial infarction, angina pectoris, coronary artery disease, or heart failure, or stroke. Annual pollutant exposures were estimated using a machine learning-based spatiotemporal model (spa
