Abstract

Many studies have linked meteorological factors to asthma attacks. However, few studies have been conducted in the subtropical monsoon climate zone. The relationship between age, temperature, humidity (other meteorological factors) and asthma attacks has not been analyzed.Disease data were collected from medical records of Xinhua hospital in Gongsu district. Meteorological data were collected from Chinese terrestrial climate data daily value data sets.Poisson generalized additive models was used and combined with distributed lag nonlinear models and piecewise linear models to model associations between daily asthma hospitalizations from 2010 to 2013 and meteorological factors. Subgroup analyses by age and season were performed.Risk of asthma hospitalizations peaked at a mean daily temperature of 10℃ and declined approximately linearly until 35℃.High humidity and low humidity were both associated with more asthma admissions. Wind speed had no significant association with asthma hospitalization. No seasonal difference in associations were observed.Asthmatic patients should limit outdoor activities in low temperature, unsuitable humidity to avoid exposure to adverse conditions.
