Abstract: Background: There is limited evidence for the impacts of meteorological changes on asthma hospital admissions in adults in Shanghai, China. Objectives: To quantitatively evaluate the short-term effects of daily mean temperature on asthma hospital admissions. Methods: Daily hospital admissions for asthma and daily mean temperatures between January 2005 and December 2012 were analyzed. After controlling for secular and seasonal trends, weather, air pollution and other confounding factors, a Poisson generalized additive model (GAM) combined with a distributed lag non-linear model were used to explore the associations between temperature and hospital admissions for asthma. Results: During the study periods, there were 15,678 hospital admissions for asthma by residents of Shanghai, an average 5.6 per day. Pearson correlation analysis found a significant negative correlation (r = −0.174, P
