Abstract

Background:Most rapid repeat pregnancies, defined as those occurring within 18 months of a previous birth, are unintended. These pregnancies are associated with later initiation of prenatal care and are more common among people with lower socio-economic status and among racially and ethnically minoritised populations.

Objectives:To assess prevalence and correlate pregnancies occurring in the immediate period after a live birth in the United States, using the Pregnancy Risk Assessment Monitoring System (PRAMS).

Methods:We assessed data from the 2009-2020 PRAMS, a population-based survey of perinatal maternal characteristics of mothers of liveborn infants in US locations. We assessed pregnancies reported during the immediate postpartum period (approximately 2-6 months post-delivery), and term this 'very rapid repeat pregnancy' (VRRP). We assessed the adjusted prevalence of VRRP from 2009 to 2020. From 2016 to 2020, we calculated adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) for maternal characteristics.

Results:The adjusted prevalence of VRRP ranged from 0.38% (95% CI: 0.29, 0.48) in 2009 to 0.76% (95% CI: 0.61, 0.91) in 2020. Demographic characteristics associated with VRRP included younger age, lower educational attainment, and being unmarried. Black mothers had a higher prevalence of VRRP compared to white mothers. Mothers who attended a healthcare visit in the 12 months preconception had a lower prevalence of VRRP as did mothers who attended a postpartum check-up, compared to their counterparts without these visits. Among those receiving prenatal care, mothers whose prenatal healthcare provider asked about postpartum contraception birth had a lower prevalence of VRRP, compared to those not asked about postpartum contraception.

Conclusions:VRRP appeared to increase over time in 2009-2020. Mothers who are younger, Black, have lower educational attainment, or who did not attend healthcare visits before or after pregnancy had a higher prevalence of VRRP and may comprise a population who would benefit from additional family planning resources.
