Unwanted pregnancy status among unmarried women seeking an abortion in Shanghai

目的:了解上海市未婚女性非意愿妊娠状况,探讨非意愿妊娠的影响因素。方法:采用现况研究的方法,应用计算机辅助自填问卷技术,于2009年10月～2010年5月对在上海市3家医院计划生育门诊寻求人工流产的未婚女性进行匿名调查。结果:44.34%被调查者发生过≥2次非意愿妊娠(396/893),其中发生过2次者占71.97%(285/396),发生过3次者占22.47%(89人)。多因素分析显示,在调整了其它可能的影响因素后,年龄大(OR=1.61,95%CI:1.45～1.78)、首次性行为年龄小(OR=0.65,95%CI:0.59～0.71)和未婚同居(OR=1.65,95%CI:1.25～2.19)的未婚女性发生多次非意愿妊娠的危险高;发生多次非意愿妊娠与多性伴(OR=1.38,95%CI:1.00～1.90)有关。结论:未婚流产女性发生多次非意愿妊娠比例高,应加强首次性行为年龄小、多性伴和未婚同居女性的安全性行为教育和流产后服务。
