Abstract

Abstract: Objective: The aim of this study was to estimate the prevalence of food insecurity among children with overweight/obesity presenting for weight management treatment and examine whether food insecurity predicts early change in body mass index (BMI), expressed as a percentage of the 95th percentile (%BMIp95). Method: Children (N = 69; ages 3–18 years) presenting to a hospital-based pediatric weight management intervention and 1 parent/guardian per child (N = 69) were included. At the first appointment, parents/guardians completed the US Household Food Security Survey Module: Six-item Short Form and a demographics questionnaire. Height and weight of the children were measured at the first and third appointments to calculate %BMIp95. Results: Among participating families, 29.0% reported experiencing food insecurity. Controlling for the ratio of income to poverty, 11.4% of the variance in %BMIp95 change from the first to third appointments was accounted for by food insecurity, ▵F (1, 66) = 8.46, p = 0.01. Children with greater food insecurity demonstrated a smaller magnitude of %BMIp95 decrease, representing a small-to-medium effect size within the context of the regression model (f2 = 0.13). Conclusion: A high proportion of families with children receiving weight management treatment reported experiencing food insecurity in comparison with US households with children. There may be unique characteristics of food insecurity, as opposed to household income alone, that explain the smaller magnitude of BMI decrease observed early in treatment. Future research should explore complex associations among food insecurity, income, BMI, and race over time.
