They are not the complications most of us imagine when we think of pregnancy. Instead of hemorrhage or preeclampsia topping the list, accidental drug overdose, homicide and suicide now account for more deaths among pregnant and recently postpartum women in the United States.
That startling finding comes from a national review of death certificates led by researchers at Columbia University, published in the New England Journal of Medicine. The team examined U.S. mortality records from 2018 through 2023, isolating women who died while pregnant or within 42 days after delivery. What emerges is a reframing of risk: injuries and intentional harm have become dominant contributors to pregnancy-associated mortality.
What the data show
Accidental overdose ranked highest, occurring at about 5.2 deaths per 100,000 births. Homicide and suicide together accounted for roughly 3.9 deaths per 100,000 births. More than half of deaths tied to overdose and interpersonal violence happened during pregnancy itself, rather than in the immediate postpartum period when traditional obstetric complications tend to peak.
Patterns differed across racial groups. Overdose and suicide were more frequent among white women, while homicide affected Black women more often. Firearms played a role in over three quarters of violent deaths, underscoring an intersection between firearm injury epidemiology and maternal health.
Overall maternal mortality did not change dramatically across the six-year window, beyond the spike seen during the COVID-19 years. Still, the relative contribution of injury and violence to pregnancy-related deaths has grown over recent decades, even as standard obstetric care has improved for conditions such as hypertension, hemorrhage and infection.
Why this matters for care and surveillance
There is a data problem behind the headlines. Pregnancy status has not always been recorded consistently on death certificates, which makes tracking trends and designing interventions harder. But where the records are clear, they point to missed opportunities in clinical screening and public health prevention. How often do obstetric clinics systematically screen for substance use, intimate partner violence and suicidal ideation with the same rigor applied to blood pressure or glucose monitoring? Not often enough, say the authors.
Overdose, homicide and suicide now exceed traditional obstetric causes of death among pregnant and recently postpartum women in the U.S.
That sentence is a call to action. Multidisciplinary approaches are needed: universal, evidence-based screening during prenatal visits; streamlined referral pathways to behavioral health and social services; safe-storage counseling and firearm-safety interventions where appropriate; and stronger community supports for substance use disorder treatment that are compatible with pregnancy.
From an epidemiologic perspective, better cause-of-death coding and routine inclusion of pregnancy status on death records would sharpen surveillance and help target resources where they will save lives. Clinicians and health systems can adapt existing maternal safety bundles to include protocols for identifying and managing overdose risk, domestic violence and suicidal behavior.
The Columbia-led study is not a call to replace obstetric vigilance. Rather, it expands the lens: maternal health is a public-health mosaic that includes mental health, addiction medicine, injury prevention and social services, as well as obstetric care. If we treat pregnancy as the narrow biomedical window alone, we miss the social and behavioral currents that steer outcomes.
Where will this lead? Better data, bolder screening and integrated care pathways could prevent many of these deaths. The question now is whether health systems and policymakers will act on the evidence—and quickly.
