Lifetime and recent rates of attempted suicide and suicidal ideation amongst the Australian Treatment Outcome Study cohort of heroin users at 11-year follow-up were examined. The mean elapsed time since heroin initiation was 20.4 years. At 11-year follow-up, 42.2% of the cohort reported ever having made a suicide attempt, 11.1% having made a first attempt subsequent to baseline. In the year preceding 11-year follow-up, 1.6% had made an attempt, suicidal ideation was reported by 10.4%, and 4.2% had a current suicide plan. After controlling for other variables, past 12 month attempts, current ideation or plans were independently associated with a current diagnosis of Major Depression (odds ratios (OR) 1.67) and more extensive polydrug use (OR 1.39), while each standard deviation higher on the SF12 physical health scale (reflecting better health) was associated with reduced odds (OR 0.66). Suicide and suicidal ideation remained a significant clinical issue for heroin users, some 20 years after their heroin use commenced.
研究考察了澳大利亚治疗结果研究队列中，海洛因使用者在 11 年随访期间的终身和近期自杀未遂和自杀意念率。海洛因起始后的平均时间过去了 20.4 年。在 11 年随访时，42.2%的队列报告曾有过自杀企图，11.1%在基线后首次尝试。在 11 年随访前一年，有 1.6%的人尝试过自杀，10.4%的人有自杀意念，4.2%的人有当前自杀计划。在控制其他变量后，过去 12 个月的尝试、当前意念或计划与当前重度抑郁症的诊断（比值比 [OR] 1.67）和更广泛的多药使用（OR 1.39）独立相关，而 SF12 身体健康量表上的每个标准偏差更高（反映健康状况更好）与降低的可能性相关（OR 0.66）。在他们开始使用海洛因大约 20 年后，自杀和自杀意念仍然是海洛因使用者的一个严重临床问题。
