The study of relationship between climate parameters and mortality in Isfahan

Climate is an important factor affecting human health. Structure and function of the human body is influenced by climate and reacts to changes in climate parameters. In this study, the relationship between climate parameters and mortality of urban population has been studied in Esfahan. Mortality data related to three diseases (cardio-vascular, respiratory and stroke) were collected form municipality of Esfahan during the 1384-1389 period and for the same period daily climate data were obtained from the meteorological organization of Iran. The relationship between mortality and climate parameters was studied with pearson correlation coefficient and T- test as a statistical examination of two population means was used to determine the seasonal variation in mortality. The results showed there was a direct correlation between mortality and some of climate parameters (humidity, pressure, and precipitation) while this correlation for sunshine and temperature (minimum, maximum and average) was reversed. Among three diseases cardiovascular showed the greatest sensitivity to climate parameters. T-test results also showed that there are significant differences (p<0.05) between seasons in disease mortality
