Observational Study
Ethnic Disparities in Trends in High BMI Among California Adolescents, 2003-2012.
Because California is home to one in eight U.S. children and accounts for the highest Medicaid and Children's Health Insurance Program spending, childhood obesity trends in California have important implications for the entire nation. California's racial/ethnic diversity and large school-based data set provide a unique opportunity to examine trends by race/ethnicity, including understudied Asian and American Indian youth, which has not been possible using national data sets. This study examined racial/ethnic disparities in prevalence of high BMI from 2003 to 2012. ⋯ Based on California's statewide data, there is evidence that racial/ethnic disparities in prevalence of high BMI have widened over time. Minority youth have either decreased more slowly or increased in prevalence compared with non-Hispanic white youth. There continues to be an urgent need for policies and interventions that effectively reduce racial/ethnic obesity prevalence disparities.
