Provincial differences in mortality exist in Iran, with child and adult mortality rates varying significantly. Life expectancy also shows considerable disparities across provinces, highlighting the need for improved death registration data.

Area of Science:

  • Public Health
  • Demography
  • Epidemiology

Background:

  • Mortality data are crucial health and socioeconomic indicators.
  • Iran's Ministry of Health and Medical Education (MOH&ME) established a comprehensive death registration system to address data gaps.
  • The system, piloted in Bushehr, expanded nationwide except for Tehran.

Purpose of the Study:

  • To estimate provincial variations in mortality levels across Iran using the established death registration system.
  • To analyze differences in child and adult mortality and life expectancy between Iranian provinces.

Main Methods:

  • Utilized 2004 death registration data from all Iranian provinces (excluding Tehran).
  • Corrected for under-enumeration using life table methods.
  • Employed the Brass Growth Balance method for adult death data adjustment where necessary, and predicted adult mortality based on literacy rates in data-scarce provinces.

Main Results:

  • Child mortality (under 5) ranged from 25 to 47 per 1000 live births.
  • Adult mortality (15-60 years) showed greater provincial variation in males than females.
  • Life expectancy varied, with Tehran province having the highest for females (73.8 years) and Sistan and Baluchistan the lowest (70.9 years). Male life expectancy ranged from 65.7 to 70.9 years.

Conclusions:

  • Significant provincial disparities in survival rates were identified across Iran.
  • The death registration system's completeness is generally acceptable, but data quality requires further improvement.
  • Expansion of death registration to include Tehran province is recommended.
