Short interpregnancy intervals lead to adverse perinatal outcomes and could be prevented with increased use of long-acting reversible contraception (LARC) in the postpartum period. The primary objective of this study was to assess which baseline characteristics are associated with the intent to use LARC among postpartum women.
This study was a substudy of baseline data from a randomized controlled trial. Eight hundred women completed a pre-intervention survey of demographics and reproductive health history and intentions. We estimated adjusted relative risks (RRs) of intent to use LARC for baseline characteristics of interest.
Three hundred three postpartum women (38%) intended to use LARC. Two out of 10 baseline characteristics were significantly associated with intent to use LARC: not trying for pregnancy at time of conception [adjusted RR, 1.6; 95% confidence interval (CI), 1.2-2.1] and no desire for another pregnancy within 2 years (adjusted RR, 1.9; 95% CI, 1.2-2.8).
High interest in LARC exists among postpartum women, particularly among women with a recent unintended pregnancy and women who do not desire pregnancy for at least 2 years. Past and future pregnancy intentions should be incorporated into future models and frameworks that evaluate postpartum contraceptive choice. Educational intervention studies are also needed to assess if LARC interest can be increased among postpartum women who are less likely to intend to use LARC but at risk for future adverse perinatal outcomes.
短的产后间隔会导致不良的围产期结局,可以通过增加产后长效可逆避孕(LARC)的使用来预防。本研究的主要目的是评估哪些基线特征与产后妇女使用 LARC 的意愿有关。
这是一项随机对照试验的基线数据的子研究。800 名妇女完成了一项关于人口统计学和生殖健康史以及意愿的预干预调查。我们估计了对 LARC 使用意愿的基线特征的调整相对风险(RR)。
303 名产后妇女(38%)打算使用 LARC。10 个基线特征中有 2 个与使用 LARC 的意愿显著相关:受孕时不打算怀孕[调整 RR,1.6;95%置信区间(CI),1.2-2.1]和 2 年内不希望再次怀孕(调整 RR,1.9;95% CI,1.2-2.8)。
产后妇女对 LARC 的兴趣很高,尤其是那些最近有意外怀孕和至少 2 年内不希望怀孕的妇女。过去和未来的怀孕意愿应该纳入未来评估产后避孕选择的模型和框架中。还需要进行教育干预研究,以评估在不太可能打算使用 LARC 但有未来不良围产期结局风险的产后妇女中,LARC 的兴趣是否可以增加。
