背景重复的自我伤害是相对常见的，并且与最终自杀的风险增加有关。目的评估自我伤害非致命性重复发生的中期风险，并找出进行自我伤害行为者的预测因素。方法自2000年7月至2003年2月在台湾南投市社区自杀行为登记系统中招募970名自杀行为者。收集了有关人口统计学和自杀方式的信息。结果队列中有90名成员在随访期内有反复的自残行为(共131次)。第一年、第二年和第四年的累积风险分别为5.7%、7.8%和9.5%。在自残事件发生后的第一年内，风险最高。独立危险因素包括女性性别和自我割伤以及药物中毒。年龄较小的影响通过方法的选择起中介作用。结论有自我伤害的个体有很高的重复风险，特别是在第一年内。自杀预防策略需要侧重于干预这一人群，以减少他们的重复。
BackgroundRepeated self-harm is relatively common and is linked with an elevated risk of eventual suicide. There has been no study of this involving a large sample from the Far East.AimsTo estimate the risk over the medium term of non-fatal repetition of self-harm and identify predictive factors in those carrying out self-harm.MethodA total of 970 individuals who had self-harmed were recruited from a community-based suicide behaviour register system in Nantou, Taiwan from July 2000 to February 2003. information regarding demography and suicide methods was collected. individuals were followed-up until December 2005 to examine the risk of repeated self-harm and independent predictive factors.ResultsNinety cohort members had repeated self-harm during the follow-up period (accounting for 131 repeated self-harm episodes in all). The cumulative risks were 5.7% for the first year, 7.8% for the second year and 9.5% for the fourth year. The risk was highest within the first year after the self-harm event. Independent risk factors included female gender and self-cutting as well as self-poisoning with drugs. Effect of younger age was mediated through the choice of methods.ConclusionsIndividuals with self-harm have a high risk of repetition, especially within the first year. Suicide prevention strategies need to focus on intervening with this population to reduce their repetition.
