【摘要】 目的随着性观念的开放，青少年婚前性行为增多，导致未婚女性人工流产率及重复流产率居高不下，严重危害着未婚青少年的身心健康。本研究旨在了解未婚女性人工流产与流产后服务现状，探索未婚女性重复流产影响因素，为保护其生殖健康，完善我国流产后服务体系提供依据。方法采用现况研究方法，对2010年7月-2011年1月，到山西省6所医院进行人工流产的18-24岁的492例未婚女性进行问卷调查，收集其人工流产知识、态度、行为的资料，应用EpiData软件录入、SPSS13.0软件分析资料，了解未婚女性人流和流产后服务现状，并将其分成重复流产组(163例)和首次流产组(329例)，使用多因素Logistic回归模型和决策树模型探讨未婚女性重复流产影响因素。结果(1)研究对象平均年龄为21.62±1.82岁，52.6%为非本市户口，47.9%为大专及以上学历，职业为公司职员、学生、服务员的分别占20.5%、20.9%、23.0%，73.6%不与父母同住，与父亲和母亲交流性话题的分别占5.3%和48.8%。(2)研究对象中，58.9%同意双方愿意就可婚前性行为，44.1%同意婚前性行为可判断双方是否合适，17.3%认为一夜情可以接受，86.0%同意今后避孕，79.5%需要生殖健康知识。(3)研究对象性病与妊娠知识得分的均分为5.74±1.69(满分9分)，避孕知识得分的均分为4.50±1.87(满分8分)，85.6%通过电视/电台/网络获得以上知识。(4)研究对象中，57.5%首次性行为年龄为19-21岁，36.8%有两个性伴以上，13.2%每次都避孕，84.9%选择避孕套，未坚持避孕者45.7%认为偶尔的性行为不会怀孕；33.1%为重复流产、最多流产5次，62.0%距上次流产时间在6个月内；此次怀孕，62.6%的研究对象因为未避孕。(5)医生服务态度较好，对流产知识有一定宣教，但50.8%的研究对象未被介绍避孕方法的种类，69.9%未被介绍避孕药具的使用方法，98.4%和88.6%未被提供避孕药具、介绍到其他地方进行计划生育宣教。(6)研究提示：学历、职业、性伴个数、避孕频率、距首次性行为时间、性伴了解避孕知识情况、性伴关心避孕问题情况、是否同居、了解生殖健康知识情况为未婚女性重复流产的影响因素。结论(1)未婚人流女性多为外来人口，职业多为服务员、学生，与父母同住者较少，且很少与父母交流性话题。(2)未婚人流女性对婚前性行为的态度开放，对今后避孕和需要生殖健康知识持肯定态度。(3)未婚人流女性生殖健康知识多来自于网络、书籍，对这方面知识的掌握程度不够深入，且有一些错误的概念和认知。(4)只有少数未婚人流女性坚持每次避孕，避孕措施多使用安全套，此次流产距上次流产时间较短。(5)医生服务态度好，对流产知识有一定的宣教，但计划生育服务欠缺。(6)多因素Logistic回归与决策树模型综合应用效果良好，提示未婚女性学历低，无职业，性伴个数多，避孕频率低，距首次性行为时间长，有同居生活，了解生殖健康知识少，性伴对避孕知识了解少、对避孕问题关心少，发生重复流产的可能性大。更多还原
