Countries with higher civilian firearm ownership had higher firearm suicide rates and a higher proportion of suicides involving firearms, but no association was found with the overall suicide rate.

The aim was to examine the cross-national association between civilian firearm ownership and suicide deaths, focusing primarily on firearm-specific suicide rates; secondary analyses examined overall suicide rates and the proportion of suicides involving firearms to assess potential method substitution. This ecological study used World Health Organization mortality data from 2017 to 2021 and 2017 Small Arms Survey estimates (firearms per 100 people); primary analyses were restricted to countries with high-quality mortality data. Suicide deaths were defined using ICD-10 codes X60 to X84 and Y87.0/Y870, and firearm suicides using X72 to X74; associations were examined using population-weighted linear regression models based on country-level mean rates and negative binomial models using country-year data to account for temporal variability. Firearm ownership ranged from 0.2 to 120.5 per 100 people, and mean overall suicide rates ranged from 0.07 to 25.92 per 100,000, with marked cross-national differences in firearm suicide. Higher firearm ownership was associated with firearm suicide rates (β = 1.17; p < 0.001) but not with overall suicide rates (β = 0.08; p = 0.71); firearm availability was also associated with the proportion of suicides involving firearms (β = 0.026; p < 0.001). The authors note substantial cross-national variation in firearm-specific suicide, with higher rates in settings where firearms are more readily available, but no corresponding increase in overall suicide mortality, and conclude that the findings suggest an association with the distribution of suicide methods.
