To gather preliminary data about menstrual hygiene product use and associated risk of intrauterine device (IUD) expulsion. We conducted an Internet-based survey using the Amazon Mechanical Turk (MTurk) platform and Researchmatch.org. Eligible participants were women at least 18 years old and self-identified as current or previous IUD users. Of 902 survey responses, 71% reported current or previous IUD use and 19.7% reported menstrual cup use. IUD users were significantly more likely than non-IUD users to use a menstrual cup or tampons. Among all IUD users, 56 individuals reported experiencing at least one expulsion (8.8%). We found a positive association between concurrent menstrual cup use and IUD expulsion (OR: 2.75, 95% CI: 1.40-5.42, = .002), but no association with concurrent tampon or pad use. Of concurrent IUD and cup users who experienced an expulsion, one reported it occurring 'while using a menstrual cup', with others reporting the expulsion during other events. Menstrual cup use may be higher than previously reported, particularly in IUD users. Concurrent menstrual cup use may increase the risk of IUD expulsion. Prospective research is necessary to fully explore the relationship between menstrual hygiene product use and IUD expulsions.
收集关于月经卫生用品使用情况及宫内节育器（IUD）脱落相关风险的初步数据。我们使用亚马逊土耳其机器人（MTurk）平台和Researchmatch.org进行了一项基于互联网的调查。符合条件的参与者为年龄至少18岁且自我认定为当前或既往IUD使用者的女性。在902份调查回复中，71%报告当前或既往使用IUD，19.7%报告使用月经杯。IUD使用者比非IUD使用者更有可能使用月经杯或 tampons。在所有IUD使用者中，56人报告经历过至少一次IUD脱落（8.8%）。我们发现同时使用月经杯与IUD脱落之间存在正相关（比值比：2.75，95%置信区间：1.40 - 5.42，P = 0.002），但与同时使用 tampons 或卫生巾无关。在同时使用IUD和月经杯且经历过脱落的使用者中，一人报告脱落发生在“使用月经杯时”，其他人报告脱落发生在其他事件期间。月经杯的使用可能比之前报告的更高，尤其是在IUD使用者中。同时使用月经杯可能会增加IUD脱落的风险。有必要进行前瞻性研究以充分探索月经卫生用品使用与IUD脱落之间的关系。
