Physical health of care-experienced young children in high-income countries: a scoping review

Abstract

Background: Good health in the early years lays the foundation for lifelong health. Children with experience of extraparental care (eg, foster, kinship, residential) have poorer outcomes than children without such experience. Common health conditions in high-income countries differ from those in low-income and middle-income countries. Health conditions also vary substantially with age. The literature examining physical health conditions affecting young care-experienced children in high-income countries has not been previously reviewed. This review addresses this gap to better understand the health needs of these children.

Methods: In this scoping review, we used a broad range of search terms in MEDLINE, CINAHL, and Web of Science Core Collection databases to identify studies of (1) care-experienced children, (2) physical health outcomes, and (3) children aged 6 years or younger. Intersecting search results were retained for screening. Results were restricted to peer-reviewed journal articles indexed before Sept 1, 2022, with titles in English. Grey literature was excluded. No restriction was placed on study design. Results were narratively synthesised and categorised by health condition.

Findings: Searches yielded 15 639 results, and 33 articles were ultimately included, covering 11 countries. Studies were concentrated in the USA (n=18, 55%) and Europe (including UK; n=10, 30%). Most studies investigated a specific health outcome or set of outcomes (n=23, 70%) with many of the remaining studies carrying out broader health reviews (n=8, 24%). Height and weight were the most frequently reported outcomes (n=10, 30%) followed by vision (n=7, 21%) and dental health (n=7, 21%). Nine studies (27%) compared outcomes in care-experienced children with outcomes in non-care-experienced controls. Synthesis of results identified poor physical development, poor dental health, low rates of immunisation, dermatological conditions, and anaemia to be substantial health problems among young children with care experience.

Interpretation: Poor physical development and anaemia suggest efforts are required to improve care-experienced children's diet. Dermatological conditions and poor dental health can be managed by additional health-care support to care-experienced children and caregivers. A strength of this work is the standardised methodology. This work is limited by the exclusion of grey literature and restriction to high-income countries.
