| Popis: | To investigate the short-term association between outdoor air pollution and outpatient visits for acute bronchitis, which is a rare subject of research in the mainland of China.A time-series analysis was conducted to examine the association of outdoor air pollutants with hospital outpatient visits in Shanghai by using two-year daily data (2010-2011).Outdoor air pollution was found to be associated with an increased risk of outpatient visits for acute bronchitis in Shanghai. The effect estimates of air pollutants varied with the lag structures of the concentrations of the pollutants. For lag06, a 10 μg/m(3) increase in the concentrations of PM10, SO(2), and NO(2) corresponded to 0.94% (95% CI: 0.83%, 1.05%), 11.12% (95% CI: 10.76%, 11.48%), and 4.84% (95% CI: 4.49%, 5.18%) increases in hospital visits for acute bronchitis, respectively. These associations appeared to be stronger in females (P0.05). Between-age differences were significant for SO(2) (P0.05), and between-season differences were also significant for SO(2) (P0.05).Our analyses have provided the first evidence that the current air pollution level in China has an effect on acute bronchitis and that the rationale for further limiting air pollution levels in Shanghai should be strengthened. |
