However, habitual exercise reduces risk for type 2 diabetes regardless of level of exposure to particulate matter air pollution
TUESDAY, April 6, 2021 (HealthDay News) — Higher levels of physical activity and lower levels of exposure to air pollution are associated with a lower risk for type 2 diabetes, according to a study published online March 4 in Diabetologia.
Cui Guo, Ph.D., from the Chinese University of Hong Kong, and colleagues evaluated the combined associations of chronic exposure to particulate matter with an aerodynamic diameter less than 2.5 Î¼m (PM2.5) and habitual physical activity with the incidence of type 2 diabetes among 156,314 Taiwanese adults participating in a longitudinal cohort (2001 to 2016).
The researchers found that compared with high physical activity, moderate and inactive or low physical activity were associated with a higher risk for diabetes (hazard ratio [HR], 1.31 and 1.56, respectively). Compared with participants with low PM2.5 exposure, participants with moderate/high PM2.5 exposure had a higher risk for type 2 diabetes (HR, 1.31 and 1.94, respectively). Compared with those who were inactive or had low physical activity and high PM2.5, the participants with high physical activity and low PM2.5 had a 64 percent lower risk for type 2 diabetes.
“Our results indicate that habitual physical activity is a safe diabetes prevention strategy for people residing in relatively polluted regions,” the authors write.
