Existing research has established child welfare (CW) clients as a vulnerable group for developing negative life trajectories, including mental health problems, work- and education-related challenges and premature mortality. Knowledge of later life conditions including suicidality of clients within child welfare services (CWS) in the Nordic countries is scarce. The overall aim is therefore to gain updated knowledge on how children and youth who have received or are receiving CWS interventions from the Nordic CWS fare in relation to suicidality. The population, intervention, comparator, outcome (PICO) framework guided the search through five multidisciplinary bibliographical databases. The population were former and current CWS clients; comparators were from the general population. Six cohort studies were identified (i.e., one Finnish study and five studies from Sweden), all showing evidence of a significantly elevated risk for suicide and suicide attempt in former CWS clients. CWS clients systematically fare worse concerning suicide and suicide attempt compared to their peers from the general population. In particular, former CWS clients should be recognized as being at high risk for suicide and suicidal behaviour later in life. These findings have substantial implications for CWS practice and service delivery regarding long-term follow-up.

北欧儿童福利服务中儿童和青少年的自杀倾向：系统评价

现有研究已将儿童福利 (CW) 客户确定为发展消极生活轨迹的弱势群体，包括心理健康问题、与工作和教育相关的挑战以及过早死亡。对北欧国家儿童福利服务 (CWS) 客户晚年生活状况的了解很少。因此，总体目标是获得有关已接受或正在接受北欧 CWS 干预措施的儿童和青年与自杀相关的最新知识。人口、干预、比较、结果 (PICO) 框架指导通过五个多学科书目数据库进行搜索。人口是以前和现在的 CWS 客户；比较者来自一般人群。确定了六项队列研究（即 一项芬兰研究和五项来自瑞典的研究），均显示前 CWS 客户的自杀和自杀未遂风险显着升高的证据。与普通人群的同龄人相比，CWS 客户在自杀和自杀未遂方面的表现更差。尤其是，前 CWS 客户应被视为在以后的生活中处于自杀和自杀行为的高风险中。这些发现对 CWS 实践和服务提供的长期随访具有重大意义。应该认识到前 CWS 客户在以后的生活中处于自杀和自杀行为的高风险中。这些发现对 CWS 实践和服务提供的长期随访具有重大意义。应该认识到前 CWS 客户在以后的生活中处于自杀和自杀行为的高风险中。这些发现对 CWS 实践和服务提供的长期随访具有重大意义。
