Introduction: Mortality statistics and cause of death is one of the main components in health planning in any community. This study has been conducted to determine and analyze the epidemiological trends for all leading causes of deaths in the last 23 years.
Methods: In this .study data related to 2,598,891 deaths, for the period of 1979 to 2001 were analyzed The data related to the number and causes of deaths were collected from 11 to 24 selected cities for the period of 1979-199-1, and from 1995 onwards from throughout the country. These data were collected by the Office of Development and Coordination of Statistical System of the Ministry of Health and Medical Education. The sources of the data are: records at the organization, far vital records, cemetries, death certificates, hospitals and health houses. The causes of death were coded and classified horsed on the International Classification of Diseases (ICD). To assess time trends in mortality over time, the proportional mortality ratio (PMR) was calculated for each year and also for five-year intervals.
Results: The results showed that the PMR due to disease of the circulatory system, and injuries and poisonings has been ranked the first and second highest groups, respectively, during the period of study. These two causes of death plus neoplasms, diseases of the respiratory system, congenital anomalies, diseases of the digestive system, infectious and parasitic diseases, neonatal diseases, and diseases of the genitourinary system are responsible for 80 percents of all deaths. The PMR for neoplasms ranked the 5th place of the causes of death in the study population during 1979-81, and then promoted to the 4th place in 1982-86, then was the 3rd place in 1987-90 and has tended to be stabilized since then. The PMR for-Infectious and parasitic diseases which ranked the 7th in 1979-81, reached to the 6i1 place in 1981-91, then again held the 7th place in 1992-96 and dropped to the 9th position in 1997-2001. In addition, PMR for diseases of the respiratory system ranked the third place during 1979-81 period, and then reached to 5th in 1997-2001.
Conclusion: In conclusion, in the past 23 years, the PMR for infectiousʹ diseases has been decreasing and PMR /for non-Infections diseases especially cancers and injuriesʹ and poisoning have been increasing. Therefore, rise of PMR for neoplasms requires ,special attention in the control and prevention programs.
