BACKGROUND Previous studies have shown an inconsistent time trend on the prevalence of anotia and microtia. Little has been reported on the epidemiologic characteristics of anotia and microtia in the Chinese population. METHODS Data from 1996-2007 were obtained from the Chinese Birth Defects Monitoring Network in China. Birth prevalence of anotia and(More)
OBJECTIVE This study aims to analyze recent trends in Down syndrome (DS) prevalence in China and evaluate the impact of prenatal diagnosis and subsequent terminations. DESIGN A birth defects surveillance-based retrospective study was adopted. METHODS On the basis of the 1996 to 2011 surveillance data for DS from Chinese Birth Defects Monitoring Network,(More)
BACKGROUND In the past two decades, the under-5 mortality rate in China has fallen substantially, but progress with regards to the Millennium Development Goal (MDG) 4 at the subnational level has not been quantified. We aimed to estimate under-5 mortality rates in mainland China for the years 1970 to 2012. METHODS We estimated the under-5 mortality rate(More)
OBJECTIVE To develop a reference of population-based gestational age-specific birth weight percentiles for contemporary Chinese. METHODS Birth weight data was collected by the China National Population-based Birth Defects Surveillance System. A total of 1,105,214 live singleton births aged ≥28 weeks of gestation without birth defects during 2006-2010 were(More)
BACKGROUND Previous studies on the mortality rate of omphalocele are limited. The risk of death of non-isolated omphalocele and that of cases of omphalocele that are diagnosed prenatally by ultrasound are unclear. This study aimed to estimate the perinatal mortality of pregnancies with omphalocele. This study also examined the potential risk of death of(More)
BACKGROUND Very little is known about the burden and determinants of stillbirths in China. We used data from a national surveillance system for health facility births to compute a stillbirth rate representative of all facility births in China and to explore sociodemographic and obstetric factors associated with variation in the stillbirth rate. METHODS We(More)
BACKGROUND Little is known about secular trends and seasonal variation in the birth prevalence of omphalocele in China. This study aimed to explore the long-term trends and seasonality of this birth defect, to provide insight into the etiology and prevention of omphalocele. METHODS A retrospective analysis of all births with omphalocele (1322 cases in 8.8(More)
BACKGROUND Birth weight percentiles by gestational age are important for assessing prenatal growth and predicting postnatal outcomes of newborns. Several countries have developed nation-specific birth weight references for twins, but China still lacks such references. METHODS AND RESULTS Birth weight data for twins born between October 2006 and September(More)
