ABSTRACT
<p><b>OBJECTIVE</b>To assess the association between air temperature and mortality in Minhang district, Shanghai.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>The findings from our study indicated that the current air temperature had an acute effect on mortality in Minhang district, Shanghai.</p>
