[Study on the relationship between air temperature and daily mortality in Minhang district, Shanghai].
2007
OBJECTIVE: To assess the association between air temperature and mortality in Minhang district, Shanghai. METHODS: Generalized additive model (GAM) to analyze time series was used. After controlling for medium-term and long-term trends,date in the week,situation of air pollution etc., this study estimated the association in virtue of quadratic curve and differential coefficient principle. RESULTS: The study was able to estimate an optimum temperature range (11.67 degrees C-20.71degrees C) by relative risk and 95% confidence interval of deaths with air temperature variation. The mortality in Minhang district, Shanghai increased along with the fluctuation of temperature deviating from this range. CONCLUSION: The findings from our study indicated that the current air temperature had an acute effect on mortality in Minhang district, Shanghai. Language: zh
