Background: Limited research exists on the relationship between food insecurity and children's adiposity and diet and how it varies by demographic characteristics in the United States.
Objective: The aim of this study was to assess the relationship between household food insecurity and child adiposity-related outcomes, measured as BMI (kg/m2) z score (BMI-z), weight status, and waist circumference, and diet outcomes, and examined if the associations differ by age, sex, and race/ethnicity.
Methods: Data collected in 2013-2015 from 5138 US schoolchildren ages 4-15 y from 130 communities in the cross-sectional Healthy Communities Study were analyzed.
