[Study on the relationship between air temperature and daily mortality in Minhang district, Shanghai].
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.


CONCLUSIONS
The findings from our study indicated that the current air temperature had an acute effect on mortality in Minhang district, Shanghai.
