We investigated the impact of commuting mode on pulmonary function in Shanghai, China.The Shanghai Putuo Study is a cross-sectional, population-based study. Our primary outcomes were forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) % predicted, and the secondary outcome was spirometric airflow obstruction. We tested the association between mode of transportation and these outcomes after adjusting for confounders.The study population consisted of 20 102 subjects. After adjusting for confounders, the change (95% CI) in FEV1 was −2.15% (−2.88– −1.42%) predicted among pedestrians, −1.32% (−2.05– −0.59%) predicted among those taking buses without air conditioning, −1.33% (−2.05– −0.61%) predicted among those taking buses with air conditioning and −2.83% (−5.56– −0.10%) predicted among those using underground railways, as compared to cyclists (the reference group). The effects of mode on FVC % predicted were in the same direction. Private car use had a significant protective effect on FVC% predicted and the risk of airflow obstruction (defined by Global Initiative for Chronic Obstructive Lung Disease but not by lower limit of normal criteria).Mode of transportation is associated with differences in lung function, which may reflect pollution levels in different transportation microenvironments.In Shanghai, China, certain modes of commuting to work are associated with reductions in pulmonary function http://ow.ly/TlyKT ER -
