There is clear evidence from the USA that access to firearms increases suicide risk, but little equivalent evidence exists in the UK. The aim of the current study is to examine the risk of suicide and all-cause mortality for people in Northern Ireland (NI) who hold a licenced firearm.
We link information on all registrations from the Firearms Certificate (FAC) Register between 2010-2020 to the health service population spine for NI residents born before 1st January 2005. Further linkage includes prescription medication data and death records with follow-up until 31st December 2020.
68,831 individuals held a FAC during the study period. FAC holders were more likely to be older, to reside in rural areas (OR 4.99, 4.89-7.83), and to come from more affluent areas (ORmost deprived 0.46, 0.43-0.50). During follow-up, 3,704 FAC holders died. 36 deaths were due to suicide, of which 16 were suicides by firearm. Only 23% of those who died by firearm suicide in NI were FAC holders. Preliminary findings indicate that after adjustment for age, area-level deprivation, and urbanicity, FAC holders had a lower risk of all-cause mortality (HR 0.64, 0.61-0.66) and death by suicide (HR 0.54, 0.39-0.76).
In contrast to findings from previous studies, individuals with a licensed firearm were less likely to die by suicide.
