Abstract:
Objectives: To explore the association between outdoor physical activities and PM2.5in Chinese adults. Methods: Data from present study were derived from the prospective urban and rural epidemiology study in China (PURE-China), outdoor physical activities were obtained by using structured and standardized questionnaire, and PM2.5and NO2values were simulated via the longitudes and latitudes of enrolled communities from NASA satellites. Finally, data form 34 064 residents were analyzed. Residents were divided into low physical activity group (<1 386 METs-min/week, n=16 369) and high physical activity group (≥1 386 METs-min/week, n=17 695). Linear correlation and binary logistic regression were used to evaluate the association between outdoor physical activities and PM2.5. Results: Of the 34 064 people included in the study, men and women accounted for 43.6% and 56.4% respectively, the average annual PM2.5concentration was 67.8 μg/m3. PM2.5was associated with high adult outdoor physical activity (OR<1), and with the increase of PM2.5cocentration, the relationship of outdoor physical activity is negative (trend test P<0.05). There was a certain association between PM2.5and high outdoor physical activity among different age groups and gender groups. Conclusions: There is a negative correlation between PM2.5and outdoor physical activity. The possibility of high outdoor physical activity decreases in proportion to the increase of PM2.5concentration. Our results suggest that people actively change their physical activity under the condition of air pollution.
