Abstrac:Background and Objectives: Life expectancy is one of the important indexes expressing the society’s social, economic, cultural, and health status. This index can also help evaluate the total planning. In addition to per capita income, gross domestic product, and female literacy rate indexes, World Health Organization uses life expectancy in order to estimate the Human Development Index which is one of the major assessment indexes of today communities. The present study aimed to determine the proportion of cardiovascular diseases, cancers, and accidents in this index.
Materials and Methods: The present descriptive, cross-sectional study was conducted using the demographic and mortality data available in the cities of Fars province, Iran. The statistical software for computation of life table was designed in Excel software and world standard population was utilized.
Results: Life expectancy at birth was different in the cities of Fars province; such a way that the lowest and highest life expectancies were found in Abadeh (67.65 years for men and 69.9 years for women) and Bavanat (76.11 years for men and 79.03 for women), respectively. Overall, the life expectancy of rural and urban females was 74.96 and 74.11 years, respectively. On the other hand, the life expectancy of rural and urban males was 73.2 and 72.3 years, respectively. The proportion of the first 3 diseases in life expectancy in different cities and sexes varied from 2.4 to 6.3 years.
Conclusion: Up to now, life expectancy was calculated for a country or a province. The results of the current study showed a great difference in life expectancy of various cities; therefore, it is necessary to compute this index based on the social factors in order to find the existing gaps. The study findings also showed that in spite of the welfare facilities in cities, urban people’s life expectancy was lower than that of the rural ones which might be due to the problems of urbanization.
