- *Proportion of boys and girls with low levels of active play, and/or greater than 2 hours per day of screen time by age category in the National Health and Nutrition Examination Survey 2001–2004. Estimates are weighted to be representative of US children age 4 to 11 years.
- † Percentage (95% Confidence Interval) calculated accounting for complex survey design.
-
§ Low active play defined as reported to play or exercise hard enough to sweat or breathe hard less than 7 times per week.
- ‡ High screen time defined as >2 hours per day; Screen time includes time spent watching television or videos, and using computers or computer-games.
-
§§ P value from logistic regressions by gender with age in years (at last birthday) as predictor, accounting for complex survey design.
- + Prevalence in girls different than prevalence in same age boys: Wald Chi-square, p < 0.1.
- *** Prevalence in girls significantly different than prevalence in same age boys: Wald Chi-square, p < 0.01.
