OBJECTIVE
Attempted suicide is the strongest known predictor of completed suicide. However, suicide risk declines over time after an attempt, and it is unclear how long the risk persists. Risk estimates are almost exclusively based on studies of less than 10 years of follow-up.
METHOD
The authors followed a cohort of 100 consecutive self-poisoned patients in Helsinki in 1963, for whom forensically classified causes of death during the following 37 years were investigated.
RESULTS
They found that suicides continued to accumulate almost four decades after the index suicide attempt.
CONCLUSIONS
A history of a suicide attempt by self-poisoning indicates suicide risk over the entire adult lifetime.
目的
自杀未遂是已知的最有力的自杀完成预测因素。然而，自杀风险在一次未遂后会随时间下降，且风险持续多久尚不清楚。风险评估几乎完全基于随访时间不足10年的研究。
方法
作者对1963年在赫尔辛基连续100例自我中毒患者组成的队列进行了随访，调查了接下来37年中法医分类的死亡原因。
结果
他们发现，在首次自杀未遂后近四十年里，自杀事件仍在不断发生。
结论
自我中毒导致的自杀未遂史表明在整个成年期都存在自杀风险。
