Contrary to national trends, West Virginia experienced an increase in the number of children in Foster Care (FC) from 2002-2012. Current evidence, though limited, suggests that FC children may be at higher risk for obesity. The purpose of this paper is to present objectively-measured body mass index (BMI) epidemiological data from 2,880 FC children in WV from 2012-13 and analysis of age, sex, and placement factors associated with overweight/obesity. Of 2,880 FC children, 40.6% (n = 1,170) were overweight or obese. Sex (χ 2 = 4.780, p=.029, φc =.041, df = 1) and age (X 2 = 53.302, p <.001, df = 2, CC =.137) were associated with overweight/obesity relative to normal weight, with higher prevalence among females and older children. Placement type and geographic region were not associated with overweight/obesity. This study exemplifies the importance of statewide screening data and suggests a need for policy or program intervention among this population of FC children and adolescents.
