PURPOSE
Gun violence traumatizes communities and places a heavy burden on the mental health of those exposed. This ecological study examines the association between gun violence exposure and suicide mortality rates in US counties for the period 1999-2020 at various urbanicity levels.
METHODS
A Bayesian hierarchical Gamma-Poisson model with state random effects was employed to model the age-adjusted suicide mortality rates which adjusted for sex ratio, urbanicity, social vulnerability, gun ownership, culture of honor, and exposure spillovers from neighbouring counties.
RESULTS
Results indicate a small significant positive association between gun violence and suicide mortality rates. Urbanicity levels do not appear to modify this association, although the association may be slightly smaller for large urban metros.
CONCLUSIONS
Gun violence exposure may be positively associated with suicide mortality in US counties.
目的
枪支暴力给社区带来创伤，并给遭受此类暴力的人群的心理健康造成沉重负担。这项生态研究考察了1999年至2020年期间美国不同城市化水平的县中，接触枪支暴力与自杀死亡率之间的关联。
方法
采用具有州随机效应的贝叶斯分层伽马-泊松模型，对经年龄调整的自杀死亡率进行建模，该模型对性别比、城市化程度、社会脆弱性、枪支拥有情况、荣誉文化以及来自邻近县的暴露溢出效应进行了调整。
结果
结果表明，枪支暴力与自杀死亡率之间存在微小但显著的正相关。城市化水平似乎并未改变这种关联，尽管对于大型城市都会区而言，这种关联可能略小。
结论
在美国各县，接触枪支暴力可能与自杀死亡率呈正相关。
