We examine the characteristics of suicide behavior and associated risk factors in the elderly in rural China, compared with the nonelderly. Paired case-control design and psychological autopsy were used for subject recruitment and data collection. The included cases were 104 suicides of the elderly aged 60 years or older, 86 suicides of the nonelderly, and sex- and age-paired controls from the same villages. Although the characteristics of suicide behavior were similar between the two age groups of victims, the elderly who died by suicide had a greater tendency to experience negative life events and not live with a spouse. Suicide of the nonelderly was associated with family history of suicide, poor social support, and impulsivity. The influence of negative life events on the risk of suicide was greater in the elderly. Thus, efforts for suicide prevention must be tailored to the needs of specific age groups.
我们研究了中国农村老年人自杀行为的特征及其相关危险因素，并与非老年人进行了比较。采用配对病例对照设计和心理解剖方法进行受试者招募和数据收集。纳入的病例包括104例60岁及以上老年人自杀案例、86例非老年人自杀案例，以及来自相同村庄的性别和年龄配对的对照。尽管两个年龄组的自杀行为特征相似，但自杀死亡的老年人经历负面生活事件的倾向更大，且未与配偶同住。非老年人自杀与自杀家族史、社会支持差和冲动性有关。负面生活事件对老年人自杀风险的影响更大。因此，自杀预防工作必须根据特定年龄组的需求进行调整。
