Abstract
Life expectancy at birth is an appropriate index representing abridged population mortality rate in the form of a number which can reflect socio conomic status in each community. Thus, the purpose of the present study was to estimate life expectancy at birth in Torbat Heydariyeh County in northeastern Iran during 2015-2016. This study was a cross-sectional study using mortality data from 2015 to 2016 among the population covered by Torbat Heydariyeh University of Medical Sciences. The raw demographic data and the number of deaths in each age group was obtained from the Vice-Chancellor’s Office for Health Affairs in the given County and then life expectancy for each age group and gender was separately calculated using the Excel software and based on the indices associated with Life Table. Life expectancy at birth in Torbat Heydariyeh County in 2015 was estimated equal to 75.70 years old (78 years old for women and 72.1 years old for men). Moreover, life expectancy rates in 2016 for women and men were 80.6 and 79.1 years old, respectively. Life expectancy rates in Torbat Heydariyeh County during 2015-2016 compared with the national values of this index in those years were higher. During one year, life expectancy at birth in the given population had an increasing trend and it was higher in men than women.
