本文采用国家“八·五”科技攻关项目“国产皮下埋植避孕方法多中心研究 (扩大应用 )”资料 ,分析中国妇女使用国产皮下埋植剂后因月经异常停用的影响因素。月经异常是皮下埋植剂最主要的停用原因 ,二年末因月经异常的累积停用率 I 型和 II 型分别为8.96 %和 7.84%。采用 COX多元逐步回归分析因月经异常停用的影响因素。结果表明 :文化程度高、产次低者因闭经停用的风险率较高 ,农民较其它职业者因闭经停用的风险率低 ,I型埋植剂因闭经停用的风险率高于 II型 ;文化程度高、体重轻、埋植时不哺乳、产次低、末次避孕方法使用 IUD或屏障法者因“其它”月经异常 (指除闭经以外的其它月经异常 )停用的风险率较高。农民较其它职业者因“其它”月经异常停用的风险率低 ;不同地区的妇女因月经异常停用的风险率不同。本研究结果提示 :应在手术前有针对性地做好咨询服务工作 ,以提高皮下埋植避孕方法的可接受性
In this paper, the “8.5” scientific and technological project “domestic subcutaneous implant contraceptive method of multi-center research (expand the application)” data, analysis of Chinese women using domestic subcutaneous implants due to abnormal menstruation disabled factors. Abnormal menstruation is the main reason for the suspension of subcutaneous implants. The cumulative discontinuation rates of type I and type II at the end of two years were 8.96% and 7.84%, respectively. Multivariate stepwise regression analysis using COX factors due to abnormal menstruation disabled. The results showed that the higher the education level, the lower the rate of closure due to the higher risk of peanuts than other professionals because of the risk of amenorrhea discontinuation of low, type I implants for amenorrhea discontinuation of the risk rate is higher than II Type; high educational level, light weight, no breast-feeding when planting, low birth rate, the last contraceptive method IUD or barrier method due to “other” menstrual abnormalities high. Peasants have a lower risk of being discontinued due to “other” menstruation than other professionals; women at different risk areas have different rates of discontinuation due to abnormal menstruation. The results of this study suggest that counseling should be done before surgery to improve the acceptability of subcutaneous implantation contraceptive methods
