Objective To systematically review literatures regarding the impact of ambient air pollution on physical activity among Chinese residents and to provide references for air quality management and health policy making in China.
Methods Studies on the impact of ambient air pollution on physical activity among Chinese residents published till August 27, 2018 for those in English and November 9, 2018 for those in Chinese were searched through Cochrane Library, PubMed, Web of Science, and China National Knowledge Infrastructure (CNKI); meanwhile, manual-searching is conducted in Google Scholar for related articles.
Results Totally 15 studies (10 published in English and 5 in Chinese) were included in the analysis. Air pollution is found to be associated with reduced physical activity level (e.g., outdoor physical activity duration, frequency of eating out) among Chinese residents. Regarding commuting mode, air pollution is associated with reduced use of non-motorized transportation (e.g., walking, cycling) and increased use of motorized transportation (e.g., car, subway).
Conclusion The level of air pollution has a significant impact on physical activity of Chinese urban residents in China.
