HealthDay News — Few US children meet all 3 guidelines for physical activity, screen time, and sleep, according to a study published online in the American Journal of Preventive Medicine.
Ciarán P. Friel, EdD, from the Feinstein Institutes for Medical Research in Manhasset, New York, and colleagues used cross-sectional data from the 2016 to 2017 National Survey of Children’s Health to describe the national prevalence estimates of US children who meet physical activity, screen time, and sleep guidelines. The guidelines recommend ≥60 minutes of physical activity per day; no more than 2 hours of screen time; and 9 to 12 hours of sleep for children aged 6 to 12 years (8 to 10 hours for those aged 13 to 17 years).
The researchers found that only 8.8% of US children met the combination of all 3 guidelines. Most (86%) attained the sleep guideline, while only 23% and 32.9% met the physical activity and screen time guidelines, respectively. There was a substantial age effect, with a decrease in the prevalence of meeting each guideline and all 3 guidelines with age.
“These data indicate that most US adolescents are transitioning into adulthood with poor movement behaviors across the 24-hour period that will likely predispose them to heightened cardiometabolic risk at an early age,” the authors write.
