深圳市福田区围产儿死亡动态监测与干预研究

A study on monitoring and intervention of perinatal death in Futian district of Shenzhen city

目的了解深圳市福田区17年围产儿死亡情况及影响因素，探讨降低围产儿死亡率的干预措施。方法对1991年1月至2007年12月围产儿死亡资料进行回顾性分析。结果17年围产儿死亡率平均为14．90‰，其中流动人口围产儿死亡率平均为21．55‰，高于常住人口12．36‰，经比较有显著性差异（Z=-3．53，P〈0．001）。早产及低出生体重、畸形、出生窒息、脐带及胎盘因素始终是导致围产儿死亡的前4位原因。结论加强流动人口孕产妇管理，重视围产期保健；提高产前诊断水平和时效性，及时诊断处理各种畸形，减少妊娠28周以上畸形儿的出生是降低围产儿死亡率的主要措施。

Objective To investigate perinatal death over a 17-year period in Futian district of Shenzhen city and its influencing factors so as to explore interventions to reduce the perinatal mortality. Methods The data of perinatal mortality over a period from Jau. 1991 to Dec. 2007 were analyzed retrospectively. Results The average perinatal mortality was 14.90‰ in the 17-year period, of which the perinatal mortality was higher in migrate population than in permanent population （21.55‰ vs 12.36‰, Z = - 3.53 ,P 〈 0. 001 ）. The major reasons of perinatal mortality were premature delivery and low birth weigh, congenital abnormality, neonatal asphyxia, umbilical and placental factors. Conclusion Strengthening management for pregnant and parturient women in migrant population, improving quality of perinatal healthcare, raising prenatal diagnosis level and timely terminating pregnancy for congenital anomalies to reduce birth of those neonates with congenital abnormalities are all measures to reduce the perinatal mortality rate.
