男男性行为者自杀意念的影响因素分析

Influencing factors of suicidal ideation among men who have sex with men

目的分析MSM自杀意念现状,并进一步探究领悟社会支持和抑郁对自杀意念的影响及其可能路径。方法研究对象为≥18岁且HIV检测结果阴性的MSM,最近1年发生男男性行为(口交/肛交)。采用横断面调查和便利抽样方法,2020年12月至2021年3月通过男性社交平台Blued 7.5软件招募MSM并开展问卷调查,问卷包括一般资料问卷、简版领悟社会支持问卷、简版流调中心抑郁量表。采用Mplus 8.3软件进行统计学分析。采用结构方程模型进行MSM自杀意念的影响因素分析。结果MSM研究对象1394人中,有自杀意念的MSM占25.7%(358/1394),领悟社会支持可对自杀意念产生直接影响(β=-0.11,P=0.009),也可通过抑郁对自杀意念产生间接影响(β=-0.18,P<0.001)。结论领悟社会支持水平越高、抑郁水平越低的MSM的自杀意念越低,通过网络社交媒体提高MSM领悟社会支持、降低其抑郁,可能是预防其产生自杀意念的手段之一。
