Abstract

The infant mortality signifies the death of the individual in the first 4 weeks of birth, and it is considered as an important indicator of growth and development. The purpose of this study is to investigate the causes of infant mortality in Western Iran over the past five years. Present research is a systematic review study. In order to achieve the conducted researches on available information banks like Indian journals, pub med, SID, Google scholar, Irandoc, Iranmedex, Magiran and Web of Knowledge, we used key words such as Mortality, infants, neonatal, Ilam, Kermanshah, Hamadan, Lorestan and west of Iran, collect and analyze data. The most commonly used method for conducting studies was descriptive. The results of this study showed that, although the mortality rate of children has decreased significantly in recent years in Iran, it still differs from the child mortality index in developed countries. Therefore, increased care during pregnancy, provision of appropriate therapies for the preservation of premature infants, and increased awareness of the symptoms of illnesses, especially respiratory disorders, are necessary in order to reduce the mortality of children
