目的了解男男性行为者(MSM)人群自杀行为现状及个体行为影响因素。方法采用应答者趋动招募抽样法(RDS)对MSM人群进行招募和自填式匿名调查。结果共调查201人,最近6个月自杀意念报告率为9%,自杀计划报告率为4.5%,自杀未遂报告率为3.5%。自杀意念报告率在不同年龄、文化、职业等人口学特征间分布差异无统计学意义(P>0.05),自杀计划、自杀未遂报告率在不同年龄、文化间分布差异有统计学意义(P<0.05),年龄小、文化低自杀计划报告率较高;不同收入自杀计划报告率差异有统计学意义(P<0.05)。自杀意念报告率与固定性伴(BF)、偶然性伴(419)、男男肛交性伴数、性病史、HIV检测和接受性病诊疗服务相关。自杀计划、自杀未遂报告率与BF、男男肛交数和性病诊疗服务相关(P<0.05)。性伴数多、有性病史、接受过HIV检测和性病诊疗服务者自杀行为报告率较高。结论 MSM人群自杀行为报告率较高,与MSM个体行为特征有关,应针对性开展自杀行为预防干预,减少自杀行为的发生。
Objective To understand the current status of suicidal behavior and the factors influencing individual behavior in MSM population. Methods The MSM population was recruited and self-administered anonymously using the Recipient-Driven Recipient Sampling (RDS). Results A total of 201 people were surveyed. The report rate of suicidal thoughts was 9% in the recent 6 months, 4.5% in suicide plans and 3.5% in attempted suicide attempts. There was no significant difference in the reported rate of suicidal ideation among different age, culture, occupation and other demographic characteristics (P> 0.05). There were significant differences in suicide plan and attempted suicide attempt among different ages and cultures (P < 0.05). The reported rate of low suicide literacy program was higher than that of the low rate suicide program (P <0.05). Rates of reported suicidal ideation were associated with BF, incidental sexual partners (419), male male anal sex partners, history of venereal disease, HIV testing and receiving venereal disease clinic services. Suicide plans and attempted suicide attempts were associated with BF, male and female anal sex and STD clinics (P <0.05). The number of sexual partners, the history of sexually transmitted diseases, HIV testing and STD clinicians suicidal behavior reported a higher rate. Conclusions There is a high incidence of suicidal behavior in MSM population, which is related to the individual behavioral characteristics of MSM. Suicide prevention should be targeted to reduce the incidence of suicidal behavior.
