BACKGROUND To determine whether use of intrauterine device (IUD) is influenced by a history of induced abortion and the type of contraceptives used until costs are covered. METHODS We analyzed data from 301 female residents in Mecklenburg-West Pomerania, an economically challenged community. The women, aged between 20 and 35 years, were entitled to receive unemployment benefits, and had access to free-of-charge oral contraceptives, ring or IUD. Cross-sectional data were analyzed using logistic regression. RESULTS There were 112 (37.2%) women with a history of induced abortion, and 46 (15.3%) reported exclusively using less effective contraceptives (e.g. condoms). In a univariate logistic regression, use of an IUD was associated with a history of having had an induced abortion. Furthermore, uptake of an IUD was associated with women who had, until costs were covered, exclusively choice to use less effective contraceptives (OR = 3.281, 95% CI: 1.717; 6.273). Both associations remained significant in a multivariate model. CONCLUSIONS Free contraceptives provided to women receiving unemployment benefits may increase the use of IUDs, especially among those with a history of an induced abortion and those using less effective contraceptives.

免费使用宫内节育器与人工流产史之间的关联：一项回顾性研究。

背景技术为了确定宫内节育器（IUD）的使用是否受到人工流产史和所用避孕药具的类型的影响，直到费用被支付为止。方法我们分析了梅克伦堡－西波美拉尼亚（Mecklenburg-West Pomerania）（一个经济困难的社区）的301名女性居民的数据。妇女年龄在20至35岁之间，有权领取失业救济金，并可以免费使用口服避孕药，避孕环或宫内节育器。使用逻辑回归分析横截面数据。结果有112例（37.2％）有人工流产史的妇女，有46例（15.3％）报告仅使用效果较差的避孕药具（例如避孕套）。在单因素逻辑回归中，宫内节育器的使用与人工流产史相关。此外，宫内节育器的摄取与那些患有，直到支付了费用，才可以选择使用效果较差的避孕药（OR = 3.281，95％CI：1.717； 6.273）。在多变量模型中，两个关联均保持显着性。结论为领取失业救济金的妇女提供免费避孕药可能会增加宫内节育器的使用，特别是在有人工流产史的妇女和使用避孕药效较差的妇女中。
