Despite increasing legal protections and supportive attitudes toward sexual minorities (e.g., those who identify as lesbian, gay, and bisexual [LGB]) in recent decades, suicidality remains more common among this population than among heterosexuals. While barriers to societal integration-or a lack of meaning, purpose, and belonging as derived from societal norms, goals, and attachment-have been widely theorized as determinants of suicidality for the general population, they have not been comprehensively explored to explain the sexual orientation disparity in suicidality. The aim of this study was to examine differences in suicidal ideation and attempts between LGB and heterosexual individuals in a nationally representative sample, and to examine barriers to societal integration as a potential explanation for any observed disparities over-and-above the influence of established contributors to sexual orientation disparity in suicidality.
Data come from the cross-sectional Swedish National Public Health Survey, which collected data from unrestricted random samples of individuals (16-84 years of age) living in Sweden, annually from 2010 to 2015 (n = 57,840 individuals [response rates: 48.1-51.3%]; 1281 (2.2%) self-identified as LGB). Analyses examined sexual orientation differences in suicidality (i.e., past-12-month ideation and attempts), and explored the role of barriers to societal integration (i.e., not living with a partner or children, unemployment, and lack of societal trust) in explaining this disparity over-and-above more commonly explored psychological (e.g., depression, substance use) and interpersonal (e.g., discrimination, victimization, lack of social support) suicidality risk factors.
Compared to heterosexuals, suicidal ideation and attempts were more common among both gay men/lesbians (adjusted odds ratio [AOR] for suicide ideation: 2.69; 95% confidence intervals [CI]: 2.09, 3.47; AOR for suicide attempts: 5.50; 95% CI: 3.42, 8.83), and bisexuals (AOR for suicide ideation: 3.83; 95% CI: 3.26, 4.51; AOR suicide attempts: 6.78; 95% CI: 4.97, 9.24). Barriers to societal integration mediated the association between sexual orientation and suicidality even in models adjusting for established risk factors for suicidality.
Our results suggest that previously under-examined factors, namely the disproportionate barriers to societal integration that LGB individuals experience, are important contributors to the substantially elevated risk of suicidality among sexual minorities. Preventive interventions should consider innovative ways to foster societal integration within sexual minority populations and to adjust hetero-centric social institutions to better include sexual minority individuals.
尽管近几十年来,针对性少数群体(例如,那些自认为是同性恋、双性恋和跨性别者的人)的法律保护和支持态度有所增加,但与异性恋者相比,他们的自杀率仍然更高。虽然社会融合的障碍——或者缺乏社会规范、目标和依恋所带来的意义、目标和归属感——已经被广泛理论化为导致普通人群自杀的决定因素,但它们尚未被全面探索,以解释性取向与自杀率之间的差异。本研究的目的是在全国代表性样本中检查同性恋、双性恋和异性恋个体之间的自杀意念和尝试差异,并研究社会融合障碍作为潜在解释,以解释任何观察到的差异,而不仅仅是既定的性取向差异的自杀因素的影响。
数据来自瑞典全国公共卫生调查的横断面研究,该调查每年从 2010 年到 2015 年从居住在瑞典的个人(16-84 岁)的无限制随机样本中收集数据(n=57840 人[回应率:48.1-51.3%];1281 人[2.2%]自我认同为 LGB)。分析检查了自杀率的性取向差异(即过去 12 个月的意念和尝试),并探讨了社会融合障碍(即与伴侣或子女不同住、失业和缺乏社会信任)在解释这种差异方面的作用,而不仅仅是更常见的探索心理(例如,抑郁、药物使用)和人际关系(例如,歧视、受害、缺乏社会支持)自杀风险因素。
与异性恋者相比,男同性恋者/女同性恋者(自杀意念的调整后优势比 [AOR]:2.69;95%置信区间 [CI]:2.09,3.47;自杀尝试的 AOR:5.50;95% CI:3.42,8.83)和双性恋者(自杀意念的 AOR:3.83;95% CI:3.26,4.51;自杀尝试的 AOR:6.78;95% CI:4.97,9.24)自杀意念和尝试更为常见。即使在调整自杀率既定风险因素的模型中,社会融合障碍也中介了性取向与自杀率之间的关联。
我们的研究结果表明,以前未被充分研究的因素,即性少数群体所经历的不成比例的社会融合障碍,是导致性少数群体自杀风险显著增加的重要因素。预防干预措施应考虑创新方法,促进性少数群体的社会融合,并调整以异性恋为中心的社会制度,以更好地包容性少数群体。
