  1. EHR = Electronic health record; SD = Standard deviation around mean difference.
  2. 1Restricted to children with valid parent-reported data.
  3. 2Children with a BMI-for-age percentile ≥ 85 were classified as overweight/obese and ≥ 95 as obese.
  4. aSignificant difference between age groups by chi-square test (P < .05).
  5. bSignificantly different from nonHispanic Whites by chi-square test (P < .05).
