背景故意自残（DSH）是未来自杀的最大危险因素。最新的风险程度的信息是缺乏。Aims为了调查DSH后自杀的风险，在一个长期的后续period.Method死亡率随访研究到2000年进行了11583例DSH后到医院1978年和1997年之间。数据来自牛津大学综合医院DSH登记处和国家统计局，以及苏格兰和北方爱尔兰的相应死亡率登记处。随访第一年的风险为0.7%（95%CI 0.6-0.9%），是一般人群年自杀风险的66倍（95%CI 52-82）。5年后的风险为1.7%，10年为2.4%，15年为3.0%。男性的风险远高于女性（风险比2.8，95%CI 2.2-3.6）。在这两种性别，它显着增加，随着年龄的增长，在初始presentation.Conclusions以下DSH有一个显着的和持续的自杀风险，这显着不同性别和年龄组。减少DSH后自杀的风险必须成为国家自杀预防战略的关键要素。
Background Deliberate self-harm (DSH) is the strongest risk factor for future suicide. Up-to-date information on the extent of risk is lacking.Aims To investigate the risk of suicide after DSH during a long follow-up period.Method A mortality follow-up study to 2000 was conducted on 11583 patients who presented to hospital after DSH between 1978 and 1997. Data were obtained from a general hospital DSH register in Oxford and the Off ice for National Statistics, and from equivalent mortality registers in Scotland and Northern Ireland.Results Three hundred patients had died by suicide or probable suicide. The risk in the first year of follow-up was 0.7% (95% Cl 0.6-0.9%), which was 66 (95% Cl 52-82) times the annual risk of suicide in the general population. The risk after 5 years was 1.7%, at 10 years 2.4% and at 15 years 3.0%. The risk was far higher in men than in women (hazard ratio 2.8,95% Cl 2.2-3.6). In both genders it increased markedly with age at initial presentation.Conclusions Following DSH there is a significant and persistent risk of suicide, which varies markedly between genders and age groups. Reduction in the risk of suicide following DSH must be a key element in national suicide prevention strategies.
