OBJECTIVE
To determine the incidence of preterm birth, its regional distribution, and associated neonatal mortality in mainland China.
METHODS
In a multicenter, hospital-based investigation of preterm birth, 2011 data were obtained from the seven administrative regions of mainland China. Between one and three subcenters were randomly selected for each administrative region, followed by secondary and tertiary hospitals within the chosen subcenters. Data were obtained from women's medical records, and obstetric and perinatal events were summarized.
RESULTS
Data for 107,905 deliveries were analyzed, which included 7769 (7.1%) preterm births (occurring between 28 and 37 weeks of pregnancy). The incidence varied among regions. Late preterm birth (between 34 and 37 weeks) accounted for 5495 (70.7%) of preterm births. The neonatal mortality rate was 33 deaths per 1000 live preterm births. Of the 254 neonatal deaths, 147 (57.9%) occurred after very preterm birth (between 28 and 32 weeks). Overall, 4519 (58.2%) preterm births occurred by cesarean.
CONCLUSION
The distribution of preterm birth across China is unbalanced, and neonatal mortality associated with preterm birth is high.
目的
确定中国大陆地区早产的发生率、区域分布及相关新生儿死亡率。
方法
在一项基于医院的多中心早产调查中，获取了2011年中国大陆七个行政区的数据。每个行政区随机选择一至三个分中心，然后在所选分中心内选取二级和三级医院。从女性病历中获取数据，并总结产科和围产期事件。
结果
分析了107,905例分娩的数据，其中包括7769例（7.1%）早产（发生在妊娠28至37周之间）。各地区发生率有所不同。晚期早产（34至37周之间）占早产的5495例（70.7%）。早产新生儿死亡率为每1000例活产早产婴儿中有33例死亡。在254例新生儿死亡中，147例（57.9%）发生在极早早产（28至32周之间）后。总体而言，4519例（58.2%）早产通过剖宫产分娩。
结论
中国早产分布不均衡，早产相关新生儿死亡率较高。
