[PMID: 36775254 DOI: 10.1016/j.jad.2023.02.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/03/2023] [Accepted: 02/04/2023] [Indexed: 02/12/2023]
Abstract
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 R2 = 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 R2 = 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.

Xuan L, Hua S, Lin L, Jianli Y. Gender differences in the predictive effect of depression and aggression on suicide risk among first-year college students. J Affect Disord 2023; 327:1-6. [PMID: 36736787 DOI: 10.1016/j.jad.2023.01.123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 02/04/2023]
Abstract
BACKGROUND Depression and aggression are related to the risk of suicide. Previous studies have associated different characteristics with depression and aggression in separate gender groups. The main aim of this study was to investigate the gender differences in the predictive effect of depression and aggression on suicide risk among first-year college students. METHODS A total of 2004 first-year undergraduates (80.5 % female, mean age = 19.4 ± 0.8 years) were surveyed by a battery of questionnaires that contained the Chinese version of the Beck scale for Suicide Ideation, the Chinese version of the 12-item Aggression Questionnaire, and the Center for Epidemiologic Studies Depression scale. RESULTS (1) Depression severity was significantly associated with the suicidality risk (r = 0.090, p < 0.01). (2) Suicide risk correlated positively with physical aggression, verbal aggression, anger, and hostility in the aggression questionnaire (r = 0.308, 0.227, 0.284, 0.277, p < 0.01). (3) A possible gender difference was noted for suicide risk in that depression degree was a significant risk factor for females but not males (R2 = 0.095, F = 41.554, p < 0.01), whereas anger was a significant predictor of suicide risk for males but not for females (R2 = 0.21, F = 25.75, p < 0.01). CONCLUSIONS Gender differences exist in the predictive effect of depression and aggression on suicide risk among first-year college students.
