Suicide is a leading cause of global mortality. Suicide clusters have recently been identified among peer networks in high-income countries. This study investigates dynamics of suicide clustering within social networks of young Kenya men ( = 532; 18-34 years). We found a strong, statistically significant association between reported number of friends who previously attempted suicide and present suicide ideation (odds ratio = 1.9; 95% confidence interval (1.42, 2.54); < 0.001). This association was mediated by lower collective self-esteem (23% of total effect). Meaning in life further mediated the association between collective self-esteem and suicide ideation. Survivors of peer suicide should be evaluated for suicide risk.
自杀是全球死亡的主要原因。最近在高收入国家的同龄人网络中发现了自杀聚集现象。本研究调查了肯尼亚年轻男性（n = 532；18 - 34岁）社交网络中的自杀聚集动态。我们发现，之前有自杀未遂经历的朋友数量与当前的自杀意念之间存在强烈的、具有统计学意义的关联（优势比 = 1.9；95%置信区间(1.42, 2.54)；P < 0.001）。这种关联由较低的集体自尊介导（占总效应的23%）。生活意义进一步介导了集体自尊与自杀意念之间的关联。同伴自杀的幸存者应接受自杀风险评估。
