摘要
背景:持枪自杀是一个重大的公共卫生问题。提高经济安全和减少社区贫困的政策可能是降低持枪自杀风险的有效策略。本研究探讨了州最低工资与持枪自杀之间的关系:州最低工资的概念来自坦普尔法律地图集,并通过法律研究进行了补充,使用修正的凯茨指数和以联邦最低工资为中心的连续变量。州一级的自杀人数来自国家生命统计系统提供的 2000 年至 2020 年多死因死亡率数据。通过对数线性回归,建立了州最低工资与枪支自杀之间的关联模型,并按人口群体进行了分层。分析在 2023 年进行:一个州的修正凯茨指数每增加一个百分点,该州的枪支自杀率就会下降 0.3%(95% CI -0.6%至-0.0%)。如果一个州的最低工资标准比联邦最低工资标准高出 1 美元,则该州的持枪自杀人数会减少 1.4%(95% CI -2.1%至-0.6%)。当按枪支拥有量的四分位数进行分层时,在最低的两个四分位数中,修改后的凯茨指数与枪支自杀率下降的相关性最为一致:结论:提高一个州的最低工资标准可能是减少枪支自杀综合措施中值得考虑的一个政策选项。这些发现扩大了如何利用经济政策减少枪支自杀的证据基础。
Association between state minimum wage and firearm suicides in the USA, 2000-2020.
Background: Firearm suicides constitute a major public health issue. Policies that enhance economic security and decrease community-level poverty may be effective strategies for reducing risk of firearm suicide. This study examined the association between state minimum wage and firearm suicide.
Methods: State minimum wage, obtained from Temple's Law Atlas and augmented by legal research, was conceptualised using the modified Kaitz Index and a continuous variable centred on the federal minimum wage. State-level suicide counts were obtained from 2000 to 2020 multiple-cause-of-death mortality data from the National Vital Statistics System. Log-linear regressions were conducted to model the associations between state minimum wage and firearm suicides, stratifying by demographic groups. Analyses were conducted in 2023.
Results: A one percentage point increase in a state's modified Kaitz Index was associated with a 0.3% (95% CI -0.6% to -0.0%) decrease in firearm suicides within a state. A US$1.00 increase in a state's minimum wage above the federal minimum wage was associated with a 1.4% (95% CI -2.1% to -0.6%) decrease in firearm suicides. When stratified by quartile of firearm ownership, the modified Kaitz Index was associated with decreases in firearm suicides most consistently in the two lowest quartiles.
Conclusion: Increasing a state's minimum wage may be a policy option to consider as part of a comprehensive approach to reducing firearm suicides. These findings expand the evidence base for how economic policies may be leveraged to reduce firearm suicides.
