Pregnancy and Postpartum Drug Overdose Deaths in the US Before and During the COVID-19 Pandemic
Abstract
Importance
Knowledge about characteristics of US pregnancy-associated decedents is needed to guide responses.
Objective
To examine individual sociodemographic characteristics and residing county's health care resources and socioeconomic factors among pregnancy-associated overdose decedents in comparison with obstetric decedents and overdose decedents who were not pregnant in the past year.
Design, Setting, and Participants
This cross-sectional, exploratory study included 1457 pregnant and postpartum overdose decedents, 4796 obstetric decedents, and 11 205 nonpregnant overdose decedents aged 10 to 44 years from 2018 to 2021. Data were analyzed August 2023.
Exposures
Decedents from the 2018-2021 Multiple Cause of Death Files linked to the 2021 Area Health Resources Files and the 2018-2021 County Health Rankings data at the county level.
Main Outcomes and Measures
Pregnancy-associated deaths were defined as deaths during pregnancy or within 1 year of pregnancy termination. This study focused on unintentional drug overdoses or drug overdoses with undetermined intent involving the most common psychotropic drugs of misuse.
Results
From 2018 to 2021, across the pregnancy-postpartum continuum, pregnancy-associated overdose mortality ratios consistently increased among women aged 10 to 44 years. Mortality ratio more than tripled among pregnant and postpartum women aged 35 to 44 years from 4.9 (95% CI, 3.0-8.0) per 100 000 mothers aged 35 to 44 years with a live birth in January to…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
