To evaluate the prevalence of lifetime non-suicidal self-injury (NSSI) among US military veterans and identify sociodemographic, military, psychiatric and clinical correlates associated with NSSI.
Data were analysed from the 2019-2020 National Health and Resilience in Veterans Study, a contemporary, nationally representative survey of 4069 US veterans. Outcomes measured included lifetime history of NSSI, trauma history, lifetime and current DSM-V mental disorders and lifetime and recent suicidal behaviours.
The overall prevalence of lifetime NSSI was 4.2% (95% confidence interval [3.6%, 4.9%]). Multivariable analyses revealed that veterans who endorsed lifetime NSSI were more likely to be younger, female, non-Caucasian, unmarried or unpartnered, and to have a lower annual household income. Veterans who endorsed lifetime NSSI reported more adverse childhood experiences and lifetime traumas and were more likely to have experienced military sexual trauma. They also were more likely to screen positive for lifetime posttraumatic stress disorder, major depressive disorder (MDD) and substance use disorders and to have attempted suicide. Finally, lifetime NSSI was associated with current MDD, generalized anxiety disorder, and substance use disorders, as well as past-year suicidal ideation.
Results of this study provide the first-known data on the epidemiology of NSSI in US military veterans. They suggest that certain correlates can help identify veterans who may be at greater risk for engaging in NSSI, as well as the potential prognostic utility of lifetime NSSI in predicting current psychiatric problems and suicide risk in this population.
评估美国退伍军人一生中非自杀性自伤（NSSI）的患病率，并确定与NSSI相关的社会人口学、军事、精神病学和临床相关因素。
对2019 - 2020年退伍军人健康与复原力全国研究的数据进行分析，该研究是一项对4069名美国退伍军人进行的具有全国代表性的当代调查。测量的结果包括NSSI的终生病史、创伤史、终生和当前的《精神疾病诊断与统计手册》第五版（DSM-V）精神障碍以及终生和近期的自杀行为。
终生NSSI的总体患病率为4.2%（95%置信区间[3.6%，4.9%]）。多变量分析显示，认可终生NSSI的退伍军人更可能年轻、女性、非白种人、未婚或无伴侣，且家庭年收入较低。认可终生NSSI的退伍军人报告有更多不良童年经历和终生创伤，且更可能经历过军事性创伤。他们也更可能终生创伤后应激障碍、重度抑郁症（MDD）和物质使用障碍筛查呈阳性，并有自杀未遂史。最后，终生NSSI与当前的MDD、广泛性焦虑障碍和物质使用障碍以及过去一年的自杀意念相关。
本研究结果提供了关于美国退伍军人NSSI流行病学的首个已知数据。这些结果表明，某些相关因素有助于识别可能有更高NSSI风险的退伍军人，以及终生NSSI在预测该人群当前精神问题和自杀风险方面的潜在预后效用。
