Background: Infants, children, and youth in foster care have frequently experienced prenatal substance exposure (PSE), neglect, and maltreatment as well as disruptions in their relationships with families. They also have great capacity for overcoming early adversities. In this synthesis of two previously conducted scoping reviews, we aimed to identify and describe literature that identifies a range of interventions that support the health and development of this population.

Methods: This review integrates and extends two previously conducted scoping reviews, one focusing on infants and one focusing on children and youth, to synthesize themes across these developmental stages. The Joanna Briggs Institute scoping review methodology was employed for the current and previous reviews. A three-step search strategy identified published studies in the English language from January 2006 to February 2020.

Results: One-hundred and fifty-three sources were included in this review. Four themes were identified: (1) early screening, diagnosis, and intervention; (2) providing theoretically grounded care; (3) supporting parents and foster care providers; and (4) intersectoral collaboration.

Conclusion:Infants, children, and youth with PSE are overrepresented in foster care. Child welfare system planning should take a multi-sectoral approach to addressing the cumulative needs of this population and their care providers over developmental ages and stages. Although research remains limited, early screening, diagnosis, and developmentally and fetal alcohol spectrum disorder-informed intersectoral interventions are critical for optimizing outcomes.

背景：寄养中的婴儿、儿童和青少年经常经历产前物质暴露 (PSE)、忽视和虐待，以及与家人的关系破裂。他们还具有克服早期逆境的强大能力。在对之前进行的两项范围界定审查的综合中，我们旨在识别和描述确定一系列支持该人群健康和发展的干预措施的文献。

方法：本综述整合并扩展了之前进行的两项范围界定审查，一项关注婴儿，另一项关注儿童和青少年，以综合这些发展阶段的主题。当前和以前的审查采用了 Joanna Briggs Institute 的范围界定审查方法。一个三步搜索策略确定了从 2006 年 1 月到 2020 年 2 月以英语发表的研究。

结果：本次审查包括 153 个来源。确定了四个主题：（1）早期筛查、诊断和干预；(2) 提供有理论根据的护理；(3) 支持父母和寄养提供者；(4) 跨部门协作。

结论：患有 PSE 的婴儿、儿童和青少年在寄养中的比例过高。儿童福利系统规划应采取多部门方法来解决这一人群及其照顾者在各个发育年龄和阶段的累积需求。尽管研究仍然有限，但早期筛查、诊断以及发育和胎儿酒精谱系障碍知情的跨部门干预对于优化结果至关重要。
