Trial summary

Rates of suicide among young Alaska Native males are over ten-fold higher than among a similar age cohort in the rest of the United States. A high proportion of these deaths are associated with firearms. Read more about this study

About this study

Rates of suicide among young Alaska Native males are over ten-fold higher than among a similar age cohort in the rest of the United States. A high proportion of these deaths are associated with firearms. Firearms are an important part of the subsistence lifestyle of this population, however restriction of access to guns by youth may be a promising strategy to reduce the risk of suicides in this population. Previous research conducted in the first phase of this project has demonstrated that about 75% of homes in rural southwest Alaskan villages have guns, and only about 15% of these guns are locked; 6% are loaded.

The aims of this specific phase of the study to execute a randomized trial of an intervention to improve firearm storage practices among residents of selected villages. Our hypothesis is that households receiving training and equipment to store firearms in gun lockers will be more likely to store their guns locked at 12 months, compared to households not receiving the intervention.

Read the detailed description

Rates of suicide among young Alaska Native males are over ten-fold higher than among a similar age cohort in the rest of the United States. A high proportion of these deaths are associated with firearms. Firearms are an important part of the subsistence lifestyle of this population, however restriction of access to guns by youth may be a promising strategy to reduce the risk of suicides in this population. Recent work by the HIPRC has shown that locked guns are associated with a 73% reduced risk of suicide, compared to unlocked guns. Similar protective associations were found for unloaded guns. A recent pilot project to improve the storage of guns conducted in southwest Alaska increased the proportion of households having all guns locked from 15% to 85%. The aims of this proposed study are to estimate the prevalence of firearm ownership and of specific firearm storage practices among residents living in the Bristol Bay and Yukon-Kuskokwim regions of southwest Alaska and to work with the Alaska Native health corporations to plan and execute a randomized trial of an intervention to improve firearm storage practices among residents of selected villages. This 3-year study consists of two phases.

The first phase is a regional survey of households within 20 randomly selected villages in southwest Alaska to estimate the extent of firearm ownership and existing storage practices in these communities. This weighted sample would be extrapolated to an overall estimate of these variables for each of the two Native corporations in the region. The second phase of the study will be a two-arm randomized controlled trial of an intervention to increase the proportion of households that store all of their firearms in a locked safe. A secondary outcome will be to reduce the proportion of home reporting the presence of a loaded gun. Households will be randomly assigned to either an early or late intervention group. The 'early' intervention group will receive the intervention at baseline. The 'late' intervention group will receive the intervention 12 months after baseline. All eligible households within participating villages will be educated about the potential protective value of safe firearm storage practices, and then be offered a gun safe to store all of their firearms. Household adults will be trained to use the safe and to carefully restrict access to the guns by youth. Each household will complete a questionnaire about storage practices and important co-variates at baseline, 12 months, and 18 months. Data will be analyzed to detect differences, between groups, in the proportion of homes with unlocked guns, and loaded guns, at 12 and 18 months after baseline. We estimate that the enrollment of 350 homes at baseline should provide 90% power to detect differences of about 16-20 absolute percentage point difference between groups, depending on the baseline prevalence of these variables. This study has the potential to have an important effect on firearm storage patterns in a population at high risk for suicide. If proven successful, it could be disseminated throughout Alaska and other high risk communities.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Installation of gun locker in householdOther

    Also called Gun safes, Gun cabinets

    Households were randomized to 'early' and 'late' arms. Each household received a gun locker, which was installed in the household. Early arm received gun lockers at baseline.
