深圳市宝安区1998～2010年孕产妇死亡率的变化趋势及死亡特征分析

目的：分析深圳市宝安区1998～2010年孕产妇死亡率的变化趋势及死亡特征,为进一步降低孕产妇死亡率提供依据。方法：对深圳市宝安区1998～2010年的161例死亡孕产妇监测资料进行回顾性调查,分析孕产妇死亡率的变化及死亡特征。结果：孕产妇死亡率从1998年的96.8/10万下降到2010年的11.9/10万,13年平均孕产妇死亡率为37.1/10万,呈逐年下降趋势（χ2=56.24,P=0.000）。死亡的主要原因为产科出血（24.2%）、羊水栓塞（23.0%）、妊娠合并内科疾病（13.0%）等。家中分娩、私人诊所分娩及孕产妇年龄≤19岁与孕产妇死亡存在强相关性,OR值分别为30.57（7.60～122.93）、27.66（6.10～125.36）及22.65（4.76～107.79）。结论：宝安区孕产妇死亡率得到有效控制,继续深入开展＂降消＂项目、加强流动人群孕产妇的管理,仍是宝安区今后妇幼保健工作的重要任务。
