Characteristics associated with interest in long-acting reversible contraception in a postpartum population

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.
