A new study shows that getting half of American 8-to 11-year-olds into 25 minutes of physical activity three times a week would save ＄21.9 billion in medical costs over their lifetimes.
The increase from the current 32 percent to 50 percent of kids taking part in exercise, active play, or sports would also result in 340, 000 fewer overweight teenagers.
"Physical activity not only makes kids feel better and helps them develop healthy habits, it's also good for the nation's bottom line, " says Bruce Y. Lee, executive director of the Global Obesity Prevention Center at Johns Hopkins University. "Our findings show that encouraging exercise and investing in physical activity when kids are young pays big dividends as they grow up."
The study, published in the journal Health Affairs, suggests an even bigger advantage if every 8 to 11-year-old in the United States exercised 75 minutes over three times in a week. In that case, the researchers estimate(估计), ＄62.3 billion in medical costs over the course of their lifetimes could be avoided and 1.2 million fewer youths would be overweight. And the money would increase if not just current 8-to-11 year olds, but every future elementary school child joined their game.
Exercise at least 25 minutes a day, three days a week, is a guideline developed for kids by the Sports and Fitness Industry Association. An overweight person's lifetime medical costs average ＄62, 331. For the overweight person, these amounts are great.
"Even a little increase in physical activity could cause billions of dollars in savings, " Lee says. He also says there are other benefits of physical activity that don't affect weight, such as improving bone density, improving mood, and building muscle.
Lee says "We need to be adding physical education programs and not cutting them. We need to encourage kids to be active, to reduce screen time and get them running around again. It's important for their physical health and the nation's financial(经济的) health."
