Abstract: To investigate the impact of meteorological elements on adult asthma hospitalization,based on the adult asthma hospitalization records of Shijiazhuang Medical Insurance Center from January 1,2013 to December 31,2016,and the meteorological and environmental observations during the same periods,the generalized additive model (GAM) was used to analyze the exposure-response relationship between the meteorological elements and the number of adult asthma hospitalization after controlling the factors such as long-term trend,holiday effects,and air pollution.The results show that different elements have different impacts on the number of adult asthma hospitalization.With 1℃ increasing in daily mean air temperature (T),daily maximum temperature (Tmax),and daily minimum temperature (Tmin),the risk of adult asthma hospitalization decreased by 0.7%,0.6%,and 0.7%,respectively.The risk of adult asthma hospitalization increased by 0.6% with the increase of daily mean air pressure (P) by 1 hPa.The risk of adult asthma hospitalization decreased by 5.2% with 1 m·s-1 increasing in daily mean wind speed (Ws).When relative humidity (RH) was less than 24%,the risk of adult asthma hospitalization reduced by 3.4% with RH increasing 1%.The risk of adult asthma hospitalization increased by 12.5% with RH increasing 1% when RH was greater than or equal to 92%.The effect of T,P,and Ws on the number of adult asthma hospitalization was strongest on the same day or on the followed day.Impacting characteristics of meteorological elements can provide a basis for healthy weather forecasting services and public defenses.
