山东省已婚育龄妇女避孕套使用情况调查

Condom use among reproductive-aged women in Shandong province

目的调查农村已婚育龄妇女避孕套使用状况及分析避孕失败原因，以提高避孕套使用效率，减少非意愿妊娠。方法采用横断面调查方法，分层整群随机抽样问卷调查山东省8个市县农村20543名已婚育龄妇女在2002年1月-2005年6月期间的生育避孕情况；采用病例对照研究方法，分析使用避孕套避孕的失败率和危险因素。结果近3年的避孕模式中，单纯使用避孕套的比例为45．1％，与节育器合用的比例为38．1％。避孕套避孕失败率为11．2％。避孕套避孕失败主要原因是未能坚持使用、套破裂和套滑脱。低年龄组使用避孕套失败的危险性增加，月经规律及没有月经期症状可降低避孕套使用的失败率，怀孕次数少和无流产史与使用避孕套避孕失败呈负关联。结论山东省农村避孕套使用率不断增加。但在使用过程中存在较多问题。应加强宣传教育。提高避孕套的正确使用率。
