Factors Associated with Rapid Repeat Pregnancies in Women at High Risk for Adverse Birth Outcomes

Why It Matters

Identifying modifiable social and mental‑health factors driving rapid repeat pregnancies enables targeted prevention, potentially reducing adverse maternal and infant outcomes and health‑care costs.

Key Takeaways

• 26% of participants experienced rapid repeat pregnancy.
• Anxiety doubled odds of rapid repeat pregnancy.
• Food insecurity nearly doubled rapid repeat pregnancy risk.
• Younger age at first birth increased repeat pregnancy likelihood.
• Married women had higher repeat pregnancy odds than unmarried.

Pulse Analysis

Rapid repeat pregnancy (RRP) remains a persistent public‑health challenge, contributing to higher rates of preterm birth, low birth weight, and maternal complications. Nationally, RRP prevalence hovers around 15‑20 percent, but the WeCare study in central Indiana reports a striking 26 percent among women engaged in a community health worker (CHW) program. This elevated figure underscores how socioeconomic stressors and limited access to comprehensive reproductive counseling can amplify risk, especially in populations already facing health inequities.

The Indiana cohort reveals a nuanced risk profile: each additional year of age at first birth modestly lowers RRP odds, while anxiety nearly doubles the likelihood of a subsequent rapid pregnancy. Repeated episodes of food insecurity also double risk, reflecting how chronic material hardship disrupts family planning and contraceptive use. A history of miscarriage emerges as a strong predictor, possibly indicating unresolved grief or heightened desire for another child. Interestingly, married participants showed higher RRP odds, whereas Hispanic women experienced lower odds, suggesting cultural and relational dynamics shape reproductive timing. These insights validate the CHW model’s capacity to surface hidden determinants through personalized coaching and referrals.

For policymakers and health systems, the findings argue for integrating mental‑health screening, nutrition assistance, and trauma-informed counseling into maternal‑health programs. Addressing anxiety and food insecurity alongside traditional clinical care could curb RRP rates and improve birth outcomes. Future research should explore how scaling CHW interventions across diverse settings impacts RRP, and whether tailored strategies for married versus unmarried women further refine prevention efforts. By confronting both psychosocial and structural barriers, health leaders can advance equity in reproductive health and reduce the long‑term societal costs of rapid repeat pregnancies.
