目的:了解宫内节育器(IUD)的使用情况及其影响检查宫内节育器的因素。方法:应用横断面调查的研究方法对流动育龄妇女进行结构式问卷调查,内容包括一般人口学特征、IUD放置及查环情况等。对流动育龄妇女人口学特征、IUD放置情况进行描述性统计分析,对有关影响检查IUD的因素进行单因素和多因素分析。结果:本次调查的1 856人使用宫内节育器作为避孕方法的流动育龄妇女中,63.42%不知道自己使用的宫内节育器种类,使用率最高的IUD是宫型IUD(10.02%),其次是O型165环(8.73%)和Tcu220C(8.35%)。Logistic回归分析发现:相对于工厂员工,白领的研究对象更倾向于查环;自租房、与他人合租、自购房的流动人口查环的可能性大于住集体宿舍的流动人口。结论:超过60%的流动育龄妇女不知道自己使用的宫内节育器种类;研究对象查环受到工作性质和居住条件的影响。今后应继续加强流动人口避孕节育知识宣传教育的同时还应广泛宣传检查IUD的重要性,以提高流动人口到现居住地检查IUD的比例。
Objectives: To understand the use of intrauterine device (IUD) and its impact on IUD detection. Methods: The cross-sectional survey method was used to carry out a structured questionnaire survey of migrant women of childbearing age, including general demographic characteristics, placement of IUDs and investigation of ring status. Demographic characteristics of migrant women of childbearing age, IUD place descriptive statistical analysis, the factors related to the impact of IUD examination by univariate and multivariate analysis. Results: Of the 8546 women of childbearing age who used IUD as contraceptive method in this survey, 63.42% did not know the type of IUD they used. The highest IUD rate was IUD (10.02%), Followed by O-ring 165 (8.73%) and Tcu220C (8.35%). Logistic regression analysis found that: relative to the factory workers, white-collar workers are more inclined to check ring; self-renting, sharing with others, since the purchase of floating population is more likely to check the ring than live in dormitories floating population. CONCLUSIONS: Over 60% of women of reproductive age do not know the type of IUD they use; the study population is affected by the nature of work and living conditions. The future should continue to strengthen knowledge and education of contraceptive knowledge of floating population should also be widely publicized the importance of checking the IUD in order to improve the proportion of floating population to live in place to check the IUD.
