Pregnancy-Associated Firearm Mortality in the U.S., 2008-2019

This study analyzed the contribution of firearms to pregnancy-associated mortality from homicide and suicide.

This was a retrospective cohort study using the Centers for Disease Control and Prevention's National Violent Death Reporting System from 2008 to 2019. Women aged 15-44 years who died by suicide (intentional self-harm) and homicide where a firearm was involved were included. Persons without known pregnancy status were excluded. Pregnancy-associated deaths were defined as those that occurred during pregnancy or within 1 year of pregnancy (early and late postpartum). Sociodemographic characteristics and social and circumstantial differences were compared between pregnancy-associated and nonpregnant-associated deaths. Data analysis was conducted in 2022-2023.

A total of 1,803 homicide and 1,929 suicide deaths from firearms were included. Twenty-two percent (n=388) and 11% (n=212) of firearm homicides and suicides, respectively, were pregnancy associated. Victims of pregnancy associated homicide were predominantly Black (54.8%), were single (76%), and had high school diploma or equivalent degree (41.2%). Victims of pregnancy-associated suicide were predominantly White (80.5%). Among pregnancy-associated homicides and suicides, deaths occurred more frequently during pregnancy (63.4% and 40.3%). Pregnancy-associated homicides more frequently occurred in the victim's home than nonpregnancy-associated homicides (51.5% vs 46.7%, p=0.02) and was related to ongoing conflict or violence between a current or former partner (61.6% vs 51.9%, p<0.001). Pregnancy-associated suicides more frequently occurred in those who experienced intimate partner violence within a month of death than non-pregnancy-associated suicide (4.2% vs 1.3%, p=0.005).

Although there are differences in demographic characteristics between victims, interpersonal violence is associated with both pregnancy-associated homicides and suicides where a firearm was involved.
