Tala Fakhouri, epidemic intelligence service officer at the Centers for Disease Control and Prevention, looked at national survey data involving elementary school kids.
The study found only 2-in-5 children met both screen time and physical activity recommendations. Fakhouri says 70 percent got at least 60 minutes of physical activity a day, and 54 percent spent no more than 2 hours a day before a screen, as recommended.
"This means that less TV does not necessarily predict more physical activity," Fakhouri said.
The study was published in the journal Journal of the American Medication Association's Pediatrics.
