The 5-year-old payoff
From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.
Physically active 5-year-olds seem to get a benefit that lingers. Kathleen Janz of the University of Iowa saw it in measurements of 333 kids, using a special scanner that measures bone, fat and muscle, and a device that measures movement.
[Kathleen Janz speaks] "Kids who were active at 5 got something that stayed with them – they got a benefit that was sustained – so that even at later, at age 8 and 11, when they may or may not have been active, they were still leaner than their peers."
The average 5-year-old got 30 minutes of moderate to vigorous activity a day – and every 10 minutes above that meant the kid weighed a third of a pound less at ages 8 and 11.
The study in the American Journal of Preventive Medicine was supported by the National Institutes of Health.
