Background & Objectives: The recent researches on mortality in Iran in the past 3 decades have obviously emphasized cardiovascular diseases, unintentional injuries, and neoplasms as the most important causes of shortening Iranian’s lives. We investigated the role of these major causes on the mortality patterns in Fars in 2006. Methods: The number of registered deaths by age and sex and the distribution of death by cause in Fars in 2006 were derived from the Death Register System of Ministry of Health (MoH). We used the 2006 census to obtain the information on the population exposed to death. The mortality of the people over 5 years of age was estimated and corrected using the Brass Growth Balance method. The mortality rate of the children under the age of 5 was estimated by indirect methods and the data were analyzed using the multi-decrement life table. Results: Life expectancy was 70.3 years in Fars, about 69 years in males and 72 years in females, in 2006. The results showed that 3 main causes of death were responsible for reducing life expectancy of about 11 years in men and women in Fars. Detailed results revealed that cardiovascular diseases and unintentional injuries played more important roles in the decrease. Unintentional injuries plays more major role in decreasing life expectancy in males than females. Conclusion: Special attention should be paid to the risk factors of cardiovascular diseases in both genders and unintentional injuries in males in Fars to reduce the mortality level and increase the life expectancy.
