英文摘要：

Background Population based epidemiologic study on the main diseases and birth status of liveborn neonates remains scarce in China, especially in rural areas where a large number of neonates are born. The aim of this study was to establish an epidemiological basis of live births in Julu County, a representative of the northern and mid-western parts of China in terms of demography, disease pattern and women and children＇s health care infrastructure.Methods The perinatal data of all live births were prospectively collected in three participating county-level hospitals from September 1, 2007 to August 30, 2008.Results There were 5822 live births in these hospitals. Among all live births, 53.7% were male and 4.5% were bornprematurely. Mean （SD） birth weight （BW） was （3348±503） g. The low （〈2500 g） and very low BW （〈1500 g） infants accounted for 3.8% and 0.5% of the total births, with 6.5% as small for gestational age and 2.8% as multi-births.Cesarean section rate was 30.2%, of which 68.6% were elective. There were 745 infants （12.8% of the live births）admitted to local neonatal wards within 7 days of postnatal life, in which 48.3% and 19.3% were due to perinatal asphyxia and prematurity, respectively. The incidences of perinatal aspiration syndrome, transient tachypnea and respiratory distress syndrome were 4.9%, 0.6% and 0.5%, respectively. Neonatal mortality was 7.6%. （44/5822）, with 16 in delivery room and 28 in neonatal ward before discharge.Conclusions This study provided a population-based perinatal data of live births and neonatal mortality in a northern China county with limited resources. Neonatal disorders related to perinatal asphyxia remain a serious clinical problem,which calls for sustained education of advanced neonatal resuscitation and improvement in the quality of perinatal-neonatal care.
