Zgodic A, Eberth JM, Breneman C, et al. - Utilizing a spatial multilevel model and the 2016 National Survey of Children’s Health, researchers sought to estimate childhood overweight and obesity (OWO) prevalence rates at the census regional division, state, and county levels using small area estimation with poststratification. A national OWO rate of 30.7% was estimated using a sample of 24,162 children aged 10-17 years. There was significant county-to-county variation (range: 7.0% to 80.9%), with 31 of 3,143 counties having an OWO rate that differed significantly from the national rate. Estimates from counties in the Pacific region were more uncertain than those from other regions, owing to a higher proportion of underrepresented sociodemographic groups. Child-level OWO was associated with their race/ethnicity, gender, parental highest education, as well as county-level walkability, and urban-rural designation. OWO remains a critical issue for US youth, with a significant area-level variation. The additional uncertainty for underrepresented groups demonstrates the need for surveys to target a more diverse sample.
