Prior Adverse Pregnancies Linked to Greater Social Deprivation in Black and Latina Women

For millions of women, a complicated pregnancy does not end at delivery — it may signal the beginning of compounding disadvantage that persists for years. Understanding whether obstetric complications cluster with social and economic hardship is critical for designing interventions that address root causes rather than isolated symptoms, and this question carries particular urgency for Black and Latina women who already face disproportionate maternal morbidity.

Using data from the BUSY-BP cohort, researchers enrolled Black and Latina women aged 18 to 65 through a large integrated New England health system between early 2023 and mid-2024. Participants self-reported a history of four major adverse pregnancy outcomes — hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and low birth weight — and completed the CMS Accountable Health Communities screening tool, which quantifies unmet social needs across 13 domains including food security, housing stability, and transportation. The primary outcome was a high social-need burden, defined as scoring in seven or more domains. Women with a history of one or more adverse pregnancy outcomes showed meaningfully elevated odds of meeting that high-burden threshold compared with those without such histories.

This cross-sectional analysis adds important texture to what epidemiologists call the "obstetric window" hypothesis — the idea that pregnancy complications serve as early biomarkers for lifelong cardiometabolic and social vulnerability. The finding that adverse outcomes correlate with downstream social needs raises a chicken-and-egg interpretive challenge: pre-existing social deprivation likely contributes to pregnancy complications, while those complications may in turn worsen economic stability through healthcare costs, disability, and lost productivity. The study's convenience-sampled, single-system design limits causal inference and generalizability, and reliance on self-reported outcomes introduces recall bias. Nonetheless, framing obstetric history as a social-risk indicator — rather than a purely clinical one — suggests that routine postpartum social-needs screening could serve as a scalable, low-cost intervention point for a high-risk population.
