摘要
目的了解大学生自杀发生率，分析影响自杀行为的相关因素。方法采用分层整群随机抽样方法，问卷调查9808名大学生的自杀行为发生情况及相关因素。结果自杀未遂的报告率为1．7％；有无自杀未遂的大学生在自杀态度、所认识的人发生自杀行为的情况及所遭受负性生活事件方面均有显著差异。多因素logistic回归分析显示，主要影响自杀行为的危险因素是：近一年感到绝望的频率高（OR=4．23，95％CI：3．05～5．85），一级亲属有过自杀行为（OR=2．85，95％Ch1．72—4．73），认识的人中有自杀行为（OR=2．82，95％CI：2．05～3．88），已发生过性行为（OR=2．73，95％CI：1．88～3．96），近一个月因心理问题对学习或日常生活有影响（OR=2．53，95％CI：1．80～3．56），女性（OR=2．47，95％CI：1．77～3．45）及其他有血缘关系的亲属有过自杀行为（OR=2．36，95％CI：1．63～3．41）。结论大学生的自杀行为受心理、生物、社会因素的共同作用，必须采取针对性措施对自杀行为实施有效干预。
