Social isolation and firearm secure storage in the USA: results from the 2022 BRFSS

Background: Firearm secure storage (ie, storing firearms unloaded and locked) is recommended to reduce unintentional injuries and suicides. However, the relationship between psychological states, such as social isolation, and firearm secure storage practices is under-researched. Methods: Data are from 7136 individuals with firearms in their households from the 2022 Behavioral Risk Factor Surveillance System. Multinomial logistic regression was used to explore the relationship between social isolation and firearm storage. Results: Among respondents, 71.6% reported storing firearms unloaded, 14.2% stored firearms loaded and locked and 14.2% stored firearms loaded and unlocked. Most respondents reported feeling ‘never’ (40.7%) or ‘rarely’ (33.3%) socially isolated, with 18.7% reporting ‘sometimes’, 4.3% ‘usually’ and 3.0% ‘always’ feeling socially isolated. Covariate-adjusted multinomial logistic regression analysis revealed that respondents who felt ‘always’ socially isolated had an over threefold greater risk of storing firearms loaded and unlocked (relative risk ratio=3.733, 95% CI 1.443 to 9.662, p=0.007) compared with unloaded. Conclusion: Results: suggest a link between feelings of social isolation and unsecured firearm storage. Public health strategies should address both firearm safety education and the underlying issue of social isolation.
