Abstract：To quantitatively analyze the effect of air pollution on hospital admissions for respiratory diseases in Lanzhou. A semi-parametric generalized additive model (GAM) was used to analyze the exposure-effect relationship between air pollution and daily respiratory hospital visits from 2007 to 2009 in Lanzhou after controlling long time trend, the “day of week” effect and confounding factors of meteorology. At the same time, the model was established based on the sex and age groups. The three kinds of air pollutants all had certain lag effect in which PM10 lagged in 2 or 5 days, SO2 lagged in 3 days and NO2 lagged in 0 or 3 days. The relative risks of PM10, SO2, NO2 were 1.015, 1.049 and 1.040 for all hospital visits, respectively. The population with the age less than 15-year-old is the most sensitive to air pollution in Lanzhou ,followed by the population with the age more than 65-year-old. The influence of air pollution on the male is more obvious than the female.
