  1. Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared).
  2. *Proportion of boys and girls with low levels of active play, and/or greater than 2 hours per day of screen time by weight status and age category in the NHANES 2001–2004. Estimates are weighted to be representative of US children age 4 to 11 years.
  3. † Percentage (95% Confidence Interval) calculated accounting for complex survey design
  4. § low active play defined as reported to play or exercise hard enough to sweat or breathe hard <7 times per week.
  5. ‡high screen time defined as >2 hours per day. Screen time includes time spent watching television or videos, and using computers or computer-games.
  6. + Prevalence in obese children different than in non-obese children of the same age and gender: Wald Chi-square, p < 0.1.
  7. ** Prevalence in obese children significantly different than in non-obese children of the same age and gender: Wald Chi-square, p < 0.05.
  8. *** Prevalence in obese children significantly different than in non-obese children of the same age and gender: Wald Chi-square, p < 0.01.
