背景：很少有研究在非临床样本中调查随时间推移的故意自残的预测因素。通过使用瑞典斯堪尼亚全县18岁及以上人口(N=936 449)的纵向数据，我们的目的是识别非致命性诊断故意自残的危险因素。将确定有反复发生自我伤害的风险的群体。方法：从2007年斯卡恩地区医疗保健数据库中收集登记为故意自残的住院和门诊专科就诊的信息。这些伤害被研究与社会人口学因素、既往疾病、药物滥用和精神药物治疗之间的关系。结果：在随访期间，与单身、中青年、低收入和出生在北欧国家相关的被诊断为故意自残的几率增加。神经或精神疾病的存在、药物滥用和既往与攻击相关的伤害也与未来的故意自我伤害密切相关。随访期间，精神药物的使用与故意自残之间存在明显的剂量-反应关系。那些在基线之前的三年内被诊断为自我伤害的人，故意自我伤害新发作的几率增加了10倍以上。在瑞典以外的欧洲出生的受试者中，反复发生自我伤害的几率不到在瑞典出生的受试者的一半。结论：本研究以总体人群为基础，扩展了成人故意自残、重复行为及其与社会人口学变量、物质使用和疾病的关系的知识基础。
Background: Few studies investigate predictors of intentional self-injury over time in non-clinical samples. By using longitudinal data from the whole population of the county of Scania, Sweden, aged 18 years and over (N = 936 449), we aim to identify risk factors for non-fatal diagnosed intentional self-injury. Groups at risk of repeat episodes of self-injury will be identified. Methods: Information on hospital stays and outpatient specialized care visits registered as intentional self-injury was collected from the Region Skane Healthcare database in 2007. These injuries were studied in relation to sociodemographic factors, previous disease, substance abuse and psychotropic drug treatment at baseline. Results: There were increased odds of diagnosed intentional self-injury during follow-up in association with being single, of young or middle age, having low income and being born in the Nordic countries. Presence of neurological or psychiatric disease, substance abuse and previous assault-related injury were also strongly associated with future intentional self-injury. The use of psychotropic drugs showed a clear dose-response relationship with intentional self-injury during follow-up. Those diagnosed with self-injury in the 3-year period before baseline had more than 10 times increased odds of a new episode of intentional self-injury. The odds of repeated episodes of self-injury among subjects born in Europe, but outside Sweden, were less than half those seen for subjects born in Sweden. Conclusions: The present study, based on a total general population, expands the knowledge base regarding intentional self-injury in adults, repeat behaviour and its associations with sociodemographic variables, substance use and disease in both men and women.
