Abstract: The long-term effects of PM 2.5 components and green space on cardiometabolic multimorbidity (CMM) remain unclear. The study aims to investigate the associations between PM 2.5 components, green space and their interacted effects on CMM. A total of 10,300 participants were included from the China Health and Retirement Longitudinal Study (CHARLS). The associations between PM 2.5 components, green space and their interaction on CMM were examined using logistic regression model. Each interquartile range (IQR) increase in PM 2.5 and its components were positively associated with CMM. The odds ratios (OR) of CMM associated with exposure to PM 2.5 , organic matter (OM) and nitrate (NO 3 - ) were 1.326 (95% CI: 1.158-1.518), 1.232 (95%CI :1.081-1.298) and 1.119 (95%CI:1.041-1.382), respectively. The OR for CMM with each IQR increase in the Normalized Difference Vegetation Index was 0.776 (95% CI: 0.695-0.866). Green space was found to mitigate the adverse impacts of PM 2.5 and its components on CMM. Long-term exposure to PM 2.5 and its components has been positively associated with CMM. Green space may help mitigate the positive association between air pollutants and CMM.
