Neonatal mortality is accounted for significant percentage of under 5 year old mortality rate. In spite of decline in child mortality rate and with huge progress in the field of neonatal medicine, neonatal and specially early neonatal death are one of the important causes of infant mortality rate so evaluating the causes of neonatal death and specially early neonatal death is very important in every geographic area .Therefore we decided to evaluate the early neonatal mortality rate and find out their etiologies in one of the referral hospital in Tehran. This is a retrospective and descriptive study which had been done In neonatal ward and neonatal intensive care unit of Shariati hospital during 8 years. All neonates who were born in this time period and expired within first week of life were evaluated for causes and time of death .registered information were analyzed. 2050 neonates were born and 189 early neonatal death were recorded. More than half of dead neonates were under 2500 gram weight at birth and the most prevalent cause of death were respiratory diseases and then congenital anomalies. Because the most important cause of early neonatal death was low birth weight, maternal support during pregnancy and appropriate monitoring of fetal weight and health play an important role in declining neonatal mortality .Proper intervention for treatment of neonatal respiratory diseases will decrease neonatal death.

Neonatal mortality rate is one of the most important health criteria, worldwide. Understanding the major neonatal mortality causes will help to plan for better pregnancy, prenatal and neonatal care systems. This study was conducted to determine the neonatal mortality risk factors in Maraveh Tapeh County in Golestan province, north of Iran.
In this case-control study, according to either death or live in 28th day after birth, 52 neonates were considered as case group and 201 neonates were considered as control group. Data collection questionnair were adjusted and completed for each neonate.
Neonatal mortality rate was 11.76, 13.36 and 6.46 per 1000 live birth in 2011, 2012 and 2013, respectively. Five main causes of death were prematurity, events, birth defect, respiratory distress syndrome and sepsis, respectively. There was a significant relation between death and prematurity, birth weight and gender (P Prematurity and low birth weight were the most important causes of neonatal mortality in Maraveh Tapeh county in Golestan province, north of Iran.

Detection of maternal risk factors associated with neonatal mortality helps to identify high-risk infants and prevent neonatal death. It can also contribute to the design more effective prenatal care. This study was performed aiming to evaluate the maternal risk factors associated with mortality in preterm infants in Mashhad Ghaem Hospital, Iran, during 2009-2014.

This cross-sectional study was performed on 335 dead infants (23 to 40 weeks of gestation). The infants were divided into two groups, according to the history of maternal risk factors: 185 cases (55.20%) with a previous history of normal pregnancy and 150 infants (44.80%) with a history of maternal risk factors. The researcher-made questionnaire containing maternal information, neonatal characteristics, and maternal risk factors was completed. The causes of infant's death were confirmed by the hospital mortality technical committee. Data were analyzed using t and chi-square test via SPSS19.5 software. P-value less than 0.05 was considered statistically significant.

There was a statistically significant difference between the two groups in terms of age, weight, height, head circumference, length of hospital stay, being a twin, gestational age, maternal age, and mode of delivery (P < 0.05 for all). There was history of maternal risk factors in 45% of cases. The most common maternal disease was preeclampsia (14%). Asphyxia in infants with previous history of maternal risk factors, and congenital anomalies in infants with normal pregnancy, were the most common causes of death.

As the results indicated, maternal risk factors including preeclampsia, diabetes and placental abruption were involved in neonatal mortality. Maternal risk factors were identified in about half of the infants, who had died within the first week after the birth. Therefore, when these factors are identified during pregnancy, caring of infants during the first week after delivery is recommended.

Due to high neonatal mortality in developing countries and lack of knowledge about the relative importance of different causes of neonatal deaths, we carried out this study to evaluate the prevalence and causes of neonatal mortality in the population of Kerman Province. This cross-sectional study was conducted between 2008-2009. The population was all the neonates born in Kerman with the gestational age more than 20 weeks and died before the fourth week of their lives. The information was collected by trained research staff using forms; neonatal causes of death were assigned by a pediatrician on the basis of information extracted from medical records. The data were analyzed by SPSS v.15. Accordingly, 535 neonatal deaths were recorded. Final causes of death were classified as immaturity-related (36.4%), birth asphyxia (20.7%), sepsis (13.6%), congenital anomalies (13.8%), and undiagnosed causes (15.3%). Low birth weight, delivery characteristics including the educational level of birth attendant, presenting part and existing risk factors in pregnancy are mostly associated with different rates and causes of neonatal deaths. There was high prevalence of neonatal mortality in our study population. It is strongly suggested to improve health service quality in order to decrease neonatal mortality. Advancements in the care of premature infants and prevention of spontaneous preterm labor lead to a substantial decrease in neonatal mortality.
