分析评价定期集体透视宫内节育器（ＩＵＤ）人群中ＩＵＤ的避孕效果．本文对２８１４例纺织女工的ＩＵＤ使用情况进行了流行病学调查。结果表明ＩＵＤ一年净累积续用率为９５．９７／每百妇女月，显著高于文献报道的结果。其原因可能为这些ＩＵＤ使用者每年都要进行两次集体透视ＩＵＤ检查，是属于经过多次筛检的人群。其中置ＩＵＤ，在６年以上者占４３．８１％，２年以上者占７２．２１％。说明定期集体透视ＩＵＤ，对防止ＩＵＤ避孕失败是行之有效的措施。在ＩＵＤ避孕失败各种结局中．脱落、带器妊娠、意外妊娠、因症取出主要发生在置ＩＵＤ后的第一年内，分别占发生例次的５１．４７％、５２．８３％，５６．５２％和５４．２９％。在ＩＵＤ类型中金属单环的用率较低，为８７．７３％。在置ＩＵＤ的医院中，以区级（包括本单位）医院的脱落率最高（４．５０％），分别为在市级、省级医院置ＩＵＤ者的１．７—２．４倍。是否采取过其它避孕措施及对ＩＵＤ避孕常识的认识对ＩＵＤ使用情况也有一定影响。
Analyze and evaluate the contraceptive effectiveness of IUD in a population of IUDs on a regular basis. This article conducted an epidemiological survey of IUD usage of 2814 women textile workers. The results showed that the net cumulative renewal rate of IUD in one year was 95.97 per 100 women and month, which was significantly higher than the results reported in the literature.
