Many studies of lesbian, gay, and bisexual youth have demonstrated that individuals reporting a bisexual orientation have a particularly high risk of suicidal behavior and substance abuse. It has been also suggested that bisexual individuals (both men and women) have higher rates of depression and anxiety compared with homosexual and heterosexual groups.
The aim of the present article was to determine whether or not an association between bisexuality and suicidal behavior exists and to analyze risk factors for suicidal behavior in bisexual individuals.
The combined search strategies yielded a total of 339 records screened from PubMed, Scopus, and Web of Knowledge. Duplicate articles, articles that were not in English, and those that did not analyze bisexuality separately from homosexuality were excluded. A quality assessment was performed for each study included.
A careful systematic review of the literature was conducted investigating the potential bisexuality-suicidal behavior link. A total of 77 articles from peer-reviewed journals were considered, and the most relevant (N=19) were selected for this review.
Individuals reporting a bisexual orientation had an increased risk of suicide attempts and ideation compared with their homosexual and heterosexual peers. Risk factors included related victimization, peer judgments, and family rejection. Bisexual individuals also reported higher rates of mental illness and substance abuse.
Bisexual individuals may experience more psychological distress and mental health problems than individuals who identify with a homosexual or heterosexual orientation. Clinicians should consider the potential for suicidal behaviors in bisexual individuals and be alert for increased mental health problems and poor social integration.
许多针对女同性恋、男同性恋和双性恋青年的研究表明，报告双性恋取向的个体自杀行为和药物滥用的风险特别高。也有人认为，与同性恋和异性恋群体相比，双性恋个体（男性和女性）的抑郁和焦虑率更高。
本研究旨在确定双性恋与自杀行为之间是否存在关联，并分析双性恋个体自杀行为的风险因素。
从 PubMed、Scopus 和 Web of Knowledge 中综合搜索策略共筛选出 339 篇记录。排除了重复的文章、非英语的文章以及没有将双性恋与同性恋分别进行分析的文章。对纳入的每项研究进行质量评估。
对文献进行了仔细的系统综述，以调查双性恋与自杀行为之间的潜在联系。共考虑了来自同行评议期刊的 77 篇文章，并选择了最相关的（N=19）文章进行综述。
与同性恋和异性恋同龄人相比，报告双性恋取向的个体自杀未遂和自杀意念的风险增加。风险因素包括相关的受害、同伴判断和家庭排斥。双性恋个体也报告了更高的精神疾病和药物滥用率。
与同性恋或异性恋取向的个体相比，双性恋个体可能经历更多的心理困扰和心理健康问题。临床医生应考虑双性恋个体自杀行为的可能性，并警惕心理健康问题增加和社会融合不良。
