Childhood obesity and schools: Evidence from the national survey of children's health

Background: The international prevalence of childhood obesity and obesity-related diseases has received increasing attention. Applying data from the Centers for Disease Control and Prevention, we explore relationships between childhood obesity and school type, National School Lunch Program (NSLP) and School Breakfast Program (SBP) eligibility, membership in sports clubs and other sociodemographic, and household factors.

Results: Though clinically small, statistically significant effects on BMI were found for children from households eligible for the NSLP/SBP, attending public schools. They have a mean BMI value 0.401 higher than counterparts attending private schools (p
