OBJECTIVES
To estimate the prevalence and identify gender-specific risk factors associated with suicidal ideation (SI) in a nationally representative sample of U.S. military veterans.
METHODS
Data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4069 veterans. Bivariate and multivariable analyses were conducted to identify factors associated with SI in male and female veterans.
RESULTS
The prevalence of SI was significantly higher in female than male veterans (18.1 % vs. 11.2 %). In female veterans, results of a relative importance analysis revealed that the majority of explained variance in SI (Nagelkerke R = 0.54) was accounted for by lower psychological resilience (44.4 %), and history of non-suicidal self-injury (24.4 %) and alcohol use disorder (20.6 %). In male veterans, the majority of explained variance in SI (Nagelkerke R = 0.32) was accounted for by higher loneliness (19.5 %) and hostility (19.1 %), and lower purpose in life (16.3 %).
CONCLUSIONS
Suicidal ideation is prevalent among U.S. veterans, particularly in female veterans. Different risk factors emerged as strong correlates of SI in female and male veterans, which may be used to inform gender-specific suicide prevention and treatment efforts in this population.
目的
在美国退伍军人的全国代表性样本中，估计自杀意念（SI）的患病率，并确定与自杀意念相关的性别特异性风险因素。
方法
对2019 - 2020年退伍军人全国健康与复原力研究的数据进行分析，该研究调查了4069名退伍军人的全国代表性样本。进行双变量和多变量分析，以确定男性和女性退伍军人中与自杀意念相关的因素。
结果
女性退伍军人的自杀意念患病率显著高于男性退伍军人（18.1%对11.2%）。在女性退伍军人中，相对重要性分析结果显示，自杀意念中大部分可解释方差（Nagelkerke R = 0.54）由较低的心理复原力（44.4%）、非自杀性自伤史（24.4%）和酒精使用障碍（20.6%）所致。在男性退伍军人中，自杀意念中大部分可解释方差（Nagelkerke R = 0.32）由较高的孤独感（19.5%）、敌意（19.1%）和较低的生活目标（16.3%）所致。
结论
自杀意念在美国退伍军人中普遍存在，尤其是在女性退伍军人中。不同的风险因素在女性和男性退伍军人中成为自杀意念的强相关因素，这可用于为该人群中针对性别的自杀预防和治疗工作提供信息。
