Epidemiologic Transition in Iran with Emphasis on the Third Stage of Transition

Introduction: During the last half century, all indices of mortality imply theprompt and continuous decrease of nationwide mortality. Alongside reduction ofmortality, there are comprehensive forms of mortality transition causes, fromepidemical and other communicable diseases such as mothers (birth giving)mortalities and birth related ones, to other causes like chronic diseases related tolifestyle and aging.Methods: This study investigated stages of epidemiological transition inIran with emphasis on the third transition and finally predicted this trend infuture decades.Results: the results show that Iran has been through the third stage ofepidemiological transition for two recent decades since large proportion of deathsare related to chronic disease such as cardiovascular disease and life expectancyat birth has decreased to 70 years. Furthermore, signs of the fourth transition inIran have been observed in recent years, because as deaths caused by chronicdiseases have increased, the mean age of death has also increased remarkably.Conclusion: epidemiological transition dynamic and changes of death causesmust be considered according to other demographic components. Reduction ofdeath rate, fertility related changes, and as a result changes of age structure aresome causes that influence on the epidemiological transition in Iran and will beimpressive in the coming years.
