【摘要】 目的 了解闸北区居民自杀死亡流行情况，为预防和干预提供科学依据。 方法 采用描述性流行病学方法，分析闸北区1995～2004年居民自杀死亡监测资料。 结果 闸北区10年间，自杀是继跌落、交通事故之后是伤害死亡的第3位死亡原因，占伤害死亡的12.75%，自杀平均死亡率为5.40/10万，男女性自杀死亡率比例为1.08:1。自杀死亡率年龄分布存在两个高峰，20～30岁青年组及60岁以上老年组。自杀死亡率与受教育水平呈负相关，与婚姻状况明显相关。自杀死亡高峰出现在夏季，自杀方式以自缢、跳楼及煤气中毒最为普遍，自杀原因主要为家庭婚姻纠纷，不同年龄组自杀原因存在差异。 结论 自杀预防主要在于社会预防，建立由国家政府支持、社区介入、各相关学科协同的危机干预和自杀防御体系是一种发展趋势。
