IntroductionFew studies have examined county-level hotspots of veteran suicide and associated place-based contributors, limiting development of targeted community-level prevention strategies. The objectives of this national spatial analysis of all veteran suicides were to identify areas of the United States with higher-than-expected veteran suicide rates and determine county-level social and economic characteristics associated with areas of higher risk.MethodsUsing Bayesian hierarchical modeling, county-level standardized mortality ratios for veteran suicide deaths were estimated for time periods 2011-2018, 2011-2014, and 2015-2018. Adjusted relative risk, accounting for community characteristics, for each county was then estimated and associations between community characteristics and veteran suicide risk were examined. Analyses were conducted in 2023-2024.ResultsRisk of veteran suicide is predominantly concentrated in the Mountain West and West. Significant predictors of risk across all time periods were per capita number of firearm retailers (2011-2018 relative risk [RR]=1.065 [95% credible interval [CI] 1.030-1.102]), the proportion of residents who moved in the past year (2011-2018 RR=1.060 [95% CI 1.039-1.081]), the proportion of residents who live alone (2011-2018 RR=1.067 [95% CI 1.046-1.089]), the proportion of residents in rental housing (2011-2018 RR=1.041 [95% CI 1.018-1.065]), and the proportion of married residents (2011-2018 RR=0.915 [95% CI 0.890-0.941]).ConclusionsThis study contributes to a comprehensive public health approach to veteran suicide prevention by identifying where resources are needed most, and which place-based intervention targets have the largest potential for impact. Findings suggest that public health efforts to address suicide among veterans should address community-level firearm access and identify ways to alleviate deleterious effects of social fragmentation.Published by Elsevier Inc.
