Ambient PM_2.5 and Stroke: Effect Modifiers and Population Attributable Risk in Six Low- and Middle-Income Countries.

ABSTRACT:

Background and purpose

Short-term exposure to ambient fine particulate pollution (PM_2.5) has been linked to increased stroke. Few studies, however, have examined the effects of long-term exposure.

Methods

A total of 45 625 participants were interviewed and included in this study, the participants came from the Study on Global Ageing and Adult Health, a prospective cohort in 6 low- and middle-income countries. Ambient PM_2.5 levels were estimated for participants' communities using satellite data. A multilevel logistic regression model was used to examine the association between long-term PM_2.5 exposure and stroke. Potential effect modification by physical activity and consumption of fruit and vegetables was assessed.
