介绍：哺乳期闭经方法（LAM）的产后避孕是更有效的比典型的使用避孕套或避孕药。然而，由于围产期咨询不完整，LAM可能未得到充分利用。使用社交媒体招募的未生育孕妇进行试验（NCT 04601987）。我们使用描述性统计来总结data.Results：760个人筛选，627人被邀请参加，451（72%）被录取。大多数（81%）有大学学位; 79%打算母乳喂养至少1个月。只有8%的人认为纯母乳喂养在分娩后6个月内“大大”降低了怀孕的机会，2%的人表示纯母乳喂养通常比避孕药或避孕套更有效。与计划使用其他产后避孕药的受访者相比，计划使用LAM的受访者中有17%更可能知道母乳喂养延迟月经恢复（84%对44%，p ≤ 0.0001），并在月经恢复之前提供怀孕保护（54%对22%，p ≤ 0.0001）。尽管计划使用LAM的人中有25%认为纯母乳喂养可以“大大”降低怀孕风险，但只有5%的人认为LAM比避孕药更有效，只有9%的人认为它比避孕套更有效。结论/影响：第一次怀孕的美国母亲通常不知道母乳喂养对月经和生育能力的影响。提供产后避孕选择咨询的临床医生应提供更多有关LAM的信息。
Introduction:The lactational amenorrhea method (LAM) of postpartum contraception is more effective than typical use of condoms or birth control pills. However, LAM may be underutilized due to incomplete perinatal counseling.Methods:We compared perceptions of the effectiveness of postpartum contraceptives including LAM among U.S.-born nulliparous pregnant women recruited using social media for a trial (NCT04601987). We used descriptive statistics to summarize data.Results:Of 760 individuals screened, 627 were invited to participate, and 451 (72%) were enrolled. Most (81%) had a college degree; 79% intended to breastfeed for at least 1 month. Only 8% believed exclusive breastfeeding reduces the chance of pregnancy “a lot” within 6 months of delivery and 2% indicated that exclusive breastfeeding is typically more effective than birth control pills or condoms. Compared with those planning to use other postpartum contraceptives, the 17% of respondents who planned to use LAM were more likely to know that breastfeeding delays return of menses (84% versus 44%,p≤ 0.0001) and provides protection from pregnancy until menses return (54% versus 22%,p≤ 0.0001). Although 25% of those planning to use LAM believed exclusive breastfeeding reduces pregnancy risk by “a lot,” only 5% thought LAM is more effective than birth control pills and only 9% thought that it is more effective than condoms.Conclusions/Implications:First-time U.S. mothers are often unaware of breastfeeding's effects on menses and fertility. Clinicians providing counseling about postpartum contraceptive options should include more information on LAM.
