Importance Suicide attempts are prevalent among female youths, yet little is known about the subsequent development of substance use disorders. Objective To assess the association between suicide attempts among females before 20 years of age and future risk of substance use disorders. Design, Setting, and Participants In this longitudinal cohort study, females aged 8 to 19 years (hereafter referred to as youths) who attempted suicide were matched with female youths with no attempt between April 1, 1989, and March 31, 2019, in Quebec, Canada. The cohort was followed up for 31 years, for a total of 2 409 396 person-years, to identify subsequent substance use disorders. Exposures Confirmed suicide attempts among females 8 to 19 years of age. Main Outcomes and Measures The main outcome measure was hospitalization for a substance use disorder later in life. Hazard ratios (HRs) and 95% CIs for the association of suicide attempt with substance use disorders were estimated using Cox proportional hazards regression models adjusted for baseline age, mental illness, resource-limited socioeconomic status, and year at start of follow-up. Results Among 122 234 female youths (mean [SD] age, 15.6 [1.9] years), 5840 (4.8%) attempted suicide and 4341 (3.6%) developed a substance use disorder. Compared with the 116 394 matched female youths who did not attempt suicide (95.2%), those who attempted suicide had a greater risk of hospitalization for any substance use disorder during the follow-up period (HR, 6.03; 95% CI, 5.39-6.77), especially sedative or hypnotic use disorders (HR, 32.24; 95% CI, 23.29-44.64). Suicide attempt was associated with the development of sedative or hypnotic use disorders up to 5 years (HR, 66.69; 95% CI, 34.72-128.09), although risks remained elevated up to 3 decades later for all substances. Compared with those without suicide attempt, female youths with 3 or more suicide attempts had 21.20 (95% CI, 13.53-32.90) times the risk of substance use disorders, whereas female youths with 1 attempt had 5.70 (95% CI, 5.08-6.41) times the risk of these disorders. Conclusions and Relevance In this cohort study, female youths who attempted suicide had increased risk of subsequent substance use disorders compared with female youths who did not attempt suicide. These findings suggest that closer management and prevention of substance use among female youths who attempt suicide may be beneficial.

自杀未遂和女性青少年物质使用障碍的风险。

重要性 自杀未遂在女青年中很普遍,但人们对物质使用障碍的后续发展知之甚少。目的 评估 20 岁以下女性自杀未遂与未来物质使用障碍风险之间的关联。设计、背景和参与者 在这项纵向队列研究中,将 1989 年 4 月 1 日至 2019 年 3 月 31 日期间在魁北克尝试自杀的 8 至 19 岁女性(以下简称青少年)与未尝试自杀的女性青少年配对, 加拿大。该队列随访了 31 年,总计 2 409 396 人年,以确定随后的物质使用障碍。暴露 已确认 8 至 19 岁女性中有自杀企图。主要结果和措施 主要结果措施是在以后的生活中因物质使用障碍住院。使用针对基线年龄、精神疾病、资源有限的社会经济状况和随访开始年份调整的 Cox 比例风险回归模型,估算自杀未遂与物质使用障碍相关的风险比 (HR) 和 95% CI。结果 在 122 234 名女性青年(平均 [SD] 年龄,15.6 [1.9] 岁)中,5840 人 (4.8%) 企图自杀,4341 人 (3.6%) 出现物质使用障碍。与未尝试自杀的 116 394 名相匹配的女青年 (95.2%) 相比,那些曾尝试自杀的人在随访期间因任何物质使用障碍而住院的风险更大(HR,6.03;95% CI,5.39- 6.77),尤其是镇静剂或催眠剂使用障碍 (HR, 32.24; 95% CI, 23. 29-44.64)。自杀未遂与长达 5 年的镇静剂或催眠剂使用障碍的发展相关(HR,66.69;95% CI,34.72-128.09),尽管所有物质的风险在 3 年后仍然升高。与没有自杀未遂者相比,有 3 次或更多次自杀未遂的女青年患物质使用障碍的风险是 21.20 (95% CI, 13.53-32.90) 倍,而有 1 次自杀未遂的女青年是 5.70 (95% CI, 5.08-6.41) ) 倍这些疾病的风险。结论和相关性 在这项队列研究中,与未尝试自杀的女性青少年相比,尝试自杀的女性青少年随后出现物质使用障碍的风险更高。这些研究结果表明,对企图自杀的女性青少年进行更密切的管理和预防物质使用可能是有益的。自杀未遂与长达 5 年的镇静剂或催眠剂使用障碍的发展相关(HR,66.69;95% CI,34.72-128.09),尽管所有物质的风险在 3 年后仍然升高。与没有自杀未遂者相比,有 3 次或更多次自杀未遂的女青年患物质使用障碍的风险是 21.20 (95% CI, 13.53-32.90) 倍,而有 1 次自杀未遂的女青年是 5.70 (95% CI, 5.08-6.41) ) 倍这些疾病的风险。结论和相关性 在这项队列研究中,与未尝试自杀的女性青少年相比,尝试自杀的女性青少年随后出现物质使用障碍的风险更高。这些研究结果表明,对企图自杀的女性青少年进行更密切的管理和预防物质使用可能是有益的。自杀未遂与长达 5 年的镇静剂或催眠剂使用障碍的发展相关(HR,66.69;95% CI,34.72-128.09),尽管所有物质的风险在 3 年后仍然升高。与没有自杀未遂者相比,有 3 次或更多次自杀未遂的女青年患物质使用障碍的风险是 21.20 (95% CI, 13.53-32.90) 倍,而有 1 次自杀未遂的女青年是 5.70 (95% CI, 5.08-6.41) ) 倍这些疾病的风险。结论和相关性 在这项队列研究中,与未尝试自杀的女性青少年相比,尝试自杀的女性青少年随后出现物质使用障碍的风险更高。这些研究结果表明,对企图自杀的女性青少年进行更密切的管理和预防物质使用可能是有益的。
