BACKGROUND
The relationship between veteran status and firearm suicide has been evaluated previously, but multiple sources of bias limit conclusions. This study aimed to clarify the relationship between a history of military service and firearm suicide.
METHODS
Data obtained from suicide death certificates from nine states (1999-2009) were analysed. History of military service was validated using data obtained from the Department of Veterans Affairs and Department of Defense. Modified Poisson Regression with robust SEs was used to compute adjusted prevalence ratios for the common outcome of firearm use among suicide decedents.
RESULTS
Male veteran suicide decedents were 6% more likely to use firearms, and female veteran suicide decedents were 18% more likely to use firearms compared with their non-veteran peers.
CONCLUSIONS
Prior estimates based on logistic regression and death certificate reporting of veteran status may have overestimated the relationship between veteran status and firearm use among suicide decedents.
背景
退伍军人身份与枪支自杀之间的关系此前已得到评估，但多种偏倚来源限制了研究结论。本研究旨在阐明服役史与枪支自杀之间的关系。
方法
对从九个州（1999 - 2009年）的自杀死亡证明中获取的数据进行分析。使用从退伍军人事务部和国防部获得的数据对服役史进行验证。采用稳健标准误的修正泊松回归来计算自杀死亡者中枪支使用这一常见结果的调整患病率比。
结果
与非退伍军人同龄人相比，男性退伍军人自杀死亡者使用枪支的可能性高6%，女性退伍军人自杀死亡者使用枪支的可能性高18%。
结论
先前基于逻辑回归和退伍军人身份死亡证明报告的估计可能高估了退伍军人身份与自杀死亡者中枪支使用之间的关系。
