Children of color-especially Black and Indigenous children-are disproportionately overrepresented in foster care and experience barriers in accessing services and receiving physical and behavioral healthcare compared to their White counterparts. Although racial disparities in mental health outcomes of children in foster care have been examined systematically, less is known about racial disparities in their physical health outcomes. This systematic review aimed to examine disparities in physical health outcomes (i.e., general health, developmental delays and disability, chronic illness, health-compromising behaviors, all-cause mortality) of children in foster care by their race and ethnicity (PROSPERO ID: CRD42021272072). Systematic literature searches were conducted in PubMed, EMBASE, PsycINFO, CINAHL, Cochrane Library, and Psychology and Behavioral Sciences Collection. Of the 6,102 unique studies identified, 24 met inclusion criteria: peer-reviewed journal article; published from 1991 to 2021; written in English; involved children in the U.S. foster care system; children were primarily in family-based placements; included health outcomes; included children's race and ethnicity; conducted quantitative analyses; and had an observational study design. There was limited evidence to suggest racial disparities among physical health domains examined, in part, due to the small number of studies, variability across study measures and designs, how race and ethnicity were categorized, and how related results were reported. Research that disaggregates results by more nuanced race and ethnicity categories, goes beyond including race and ethnicity as control variables, and uses more robust study designs to understand where racial disparities lie is necessary to inform practice and policy efforts to attain race and health equity in child welfare.
