Combined effects of physical activity and air pollution on cardiovascular disease: A population‐based study
Journal of the American Heart Association Jun 10, 2020
Kim SR, Choi S, Keum N, et al. - Thiss tudy was sought to examine the combined effects of PA and air pollution on cardiovascular disease (CVD). Researchers analyzed a total of 189,771 adults aged ≥40 years who had undergone health examination between 2009 and 2010. They assessed PA with a questionnaire on the weekly frequency and intensity. They calculated ambient levels of particulate matter 10, 2.5 (PM10, PM2.5) by the residency of participants. Cox proportional hazard regression analysis was performed to calculate the association between CVD risk and combined impacts of PA and air pollution. This study's findings demonstrate that moderate to vigorous PA seemed to decrease the risk of CVD within groups of both high and low PM10 or PM2.5 levels. Future research is required to confirm if the health advantages of PA outweigh the potential harmful impacts resulting from increased exposure to air pollution during PA.
