Introduction
In addition to direct effects on health, the COVID-19 pandemic has had indirect effects through stress and economic hardships imposed by mitigation efforts such as lockdowns. For children, the indirect health outcomes may be comparable with direct effects, because SARS-CoV-2–related morbidity and mortality are concentrated at older ages.
One potential indirect health outcome for children is gun-related deaths owing to increased psychological strain in families in combination with school closures, which lead to greater time spent by children at home, where guns are often kept. Although studies have documented increased gun-related deaths during the pandemic, only few studies have considered children and those focused on early stages of the pandemic.1-4
Methods
This cross-sectional study analyzed gun-related deaths of children between January 1, 2014, and December 31, 2022, from the Gun Violence Archive (GVA), a repository of gun violence collected from more than 7500 law enforcement, media, government, and commercial sources (eMethods in Supplement).5 The study used publicly available data and was thus exempt from human subjects review at Harvard Medical School, and it followed the STROBE reporting guideline.
We plotted 28-day moving averages of the count of children (aged 0 to 17 years) killed, comparing mid-March 2020 onwards to the trend in prior years to account for seasonal variation in shootings. In addition, we conducted an event study regression analysis with 2922 daily observations that modeled the daily count of child gun-related deaths as a function of a cubic time-trend and adjustments for month and day of week, assuming a pandemic period beginning March 16, 2020 (eMethods in the Supplement).
We conducted subgroup analyses according to child age, median household income in the Census tract where a death occurred (using the 2019 American Community Survey), and the percentage Black or Hispanic population in the Census tract (analysis conducted because the health and economic impact of the pandemic has varied by race). We used a significance threshold of P < .05 using a 2-sided test. Stata version 15.1 (StataCorp) was used for analyses from March to April 2022.
Results
Overall, 8044 shootings were analyzed and involved 8477 children killed. Of these 8477 children, 1888 (22.3%) were aged 0 to 11 years and 6589 (77.7%) were 12 to 17 years; 1657 (19.6%) were girls, 6676 (78.8%) were boys, and 144 (1.7%) had unknown gender; and 4914 (58.0%) were from a high-minority area (defined as having more than 50% Black or Hispanic population). An increase in deaths was observed from March 16, 2020, onwards (Figure), with an estimated 1.12 (95% CI, 0.70-1.53) additional children killed per day, corresponding to an estimated 733 (95% CI, 462-1003) additional children killed over the study period.
The US Centers for Disease Control and Prevention (CDC) reports that 752 children died from COVID-19 from January 1, 2020, to December 31, 2021,6 implying that our estimated increase in child gun-related deaths was comparable with COVID-19–related deaths in children. Increases in gun-related deaths were concentrated in areas with low median income or a high percentage of Black or Hispanic population, suggesting family and neighborhood socioeconomic conditions may be important mediators. They were also greater among children aged 12 to 17 years (Table). Findings were robust to analyses that modeled linear, quadratic, and quartic time trends ...
