Note: Obesity class is defined based on age- and sex-specific percentage of the 95th BMI percentile as follows: class I (BMI 95%–119%), class II (120%–139% or BMI ≥35 kg/m²) and class III (BMI ≥140% or BMI ≥40 kg/m²). Race was based on self-reported race and ethnicity. County of residence was referred to as metropolitan, adjacent non-metro and rural.
