Introduction: Healthy life expectancy (HALE) for every country is estimable in global and national level studies, in which the used data, methodologies, and hence the estimates’ values are not necessarily completely identical. Therefore, the current study was performed to estimate healthy life expectancy for Iran’s population, with use of the national-level studies’ data and methodologies for the first time.
Methods: For estimation of life expectancy for 23 out of 28 provinces of Iran (in 2003), registered deaths for 23 provinces were used. For population of 23 provinces, information from Ministry of Health was used and its distribution was taken similar to the results of Demographic and Health Survey of year 1379 (2000), and taken also equal to results of graduation of population from year 1375 (1996) census. Life expectancy was estimated with direct method. Years Lived with Disability (YLD) was calculated from prevalence of diseases and their disability weights, and used in
Results: HALE at birth was 62.13 years for total population (95% Confidence Interval [CI]: 61.02-63.16), 61.55 years for males (95% CI: 60.61-62.50), and 62.79 years for females (95% CI: 61.84-63.71).
Conclusion: National estimate of healthy life expectancy is 4.5 years higher than similar model-based estimate by World Health Organization. The reason is difference in direct and indirect estimation methods for specific mortality rates and hence the life expectancy, and difference in burden of disability estimation methods used in national and global burden of disease studies.

Abstract
Introduction: This study models mortality changes in Iran during 1996-2011, then forecasts it until 2041. With central age-specific mortality rates at hand, annual life tables for the period 1996-2041 are constructed. The central age-specific mortality rates are also forecasted for the next 30 years (2012-2041).
Methods: First the existing mortality data were evaluated for accuracy and validity. Then they were modeled using the Lee and Carter method. Deaths registered by the National Organization for Civil Registration during 1996-2011, and Population and Housing Censuses during the period from Statistical Center of Iran were the main sources of data. The corrected and adjusted data were used for modeling change of level of mortality during 1996-2011. The models were then used to forecast mortality for the next period.
Results: The results of the analysis showed a slightly declining trend in Crude Death Rate, from 6.5 in 1996 to 6.1 per 1000 population in 2011. Male life expectancy at birth has risen from 66.3 to 71.1 years during the period. The corresponding values for females are 68.4 and 75.7 years, respectively. Life expectancy for male births is forecasted to be 74.8 years (%95 CI: 72.9-76.2) at 2041. This forecast for female births is 82.5 years (%95 CI: 79.8-84.3).
Conclusion: With current level of Crude Death Rate, Iran is among countries with low child mortality rate and elderly deaths due to low proportion of elderly population. The increasing trend in age-specific mortality rates for population aged 18-35 years seems to be the main reason for slow increase in male life expectancy at birth for the next 30 years.
