PM_2.5 exposure modifies the association of physical activity with depressive symptoms and glaucoma in middle aged and elderly Chinese.

ABSTRACT: It remains unclear that trade-off between the benefits of regular physical activity (PA) and the potentially harmful effects of exposure to PM_2.5 (particulate matter with aerodynamic diameter < 2.5 μm) in highly polluted regions. Therefore, we aimed to investigate the modification of PM_2.5 on the associations of PA volume and intensity with depressive symptoms and glaucoma in individuals with or without depressive symptoms. Data of this study was obtained from the China Health and Retirement Longitudinal Survey (CHARLS) implemented during 2011 to 2020. PA volume and intensity were measured by a standardized questionnaire; a machine learning prediction model was applied to ascertain the PM_2.5 concentrations. Cox proportional hazards regression models were em
