- A report by the World Health Organization concludes 80 percent of children between the ages of 11 and 17 aren’t physically active enough.
- The report stated that girls get less exercise than boys, possibly because of lack of access to programs.
- Experts say this global problem needs a multilayered approach to solve.
It’s not just kids in the United States.
体育投注网址Children worldwide aren’t getting enough physical activity.
That’s the main conclusion of a new World Health Organization (WHO)
The researchers report that slightly more than 80 percent of adolescents ages 11 to 17 were insufficiently physically active in 2016.
WHO says it’s the first global estimates of adolescents’ physical activity levels, a major factor in obesity, diabetes, and other health problems.
How rich the country was didn’t matter much, although nations in the Asia-Pacific region had the highest rates of insufficient physical activity, at 89 percent.
体育投注网址What did matter was gender.
体育投注网址On average, girls got less physical activity than boys. That includes the United States, where the discrepancy was more than 15 percentage points.
体育投注网址The percentage of boys getting enough physical activity actually increased slightly between 2001 and 2016, while the percentage of girls stayed the same.
Guthold says those small decreases could be due to actions such as school programs, increased participation in sports, creating new places for activities, and increased awareness of the importance of physical activity through education and media campaigns.
体育投注网址But, she said, “These actions seem to only have reached boys, not girls.”
“This is an important study in that it gives us additional data across dozens of countries to help inform the long-term planning and goal of addressing inadequate physical activity,” Kahan told Healthline. “At the same time, we have to take the data with a grain of salt.”
He says that in countries like the United States, the increased messaging about the importance of physical activity may be leading to an unintended complication.
体育投注网址“It begs the question, do these results suggest adolescents are moving more, or that they recognize that it’s important to move more and therefore they say they’re moving more?” Kahan said. “This is a common challenge with self-reported survey data.”
The other issue is that the 2001 numbers were already so high: 85 percent for girls globally and 80 percent for boys.
体育投注网址“When you have 80 percent of kids who are inactive, it gets kind of hard to have much more than that,” said , a pediatric orthopedist at the University of Wisconsin School of Medicine and Public Health who has served on the American Academy of Pediatrics’ Council on Sports Medicine and Fitness.
Part of those stories is that current training — beyond just at Nike — is often based on the physiology of male bodies.
That ties in to some possible solutions.
“The number one factor for kids participating in sports is that what they’re doing is fun,” Nemeth said. “Physical activity has to be something we’re enjoying.”
Beyond making sure it’s fun, “to make change on this is going to require a societal shift in how we view physical activity — from something to lose weight to something for overall good health,” he said.
Kahan says that tackling insufficient physical activity requires an approach similar to that used against problems such as tobacco use: both bottom-up and top-down.
“This is the only way we’ve made progress on a host of other pandemics,” he said.
Bottom-up would include building knowledge among parents, teachers, and others so they can inform and encourage children to be healthy.
体育投注网址Top-down would be decreasing barriers to physical activity. That could include things such as building more gym time into school life and addressing the environment, so cities are more walkable and have more places and opportunities for physical activity.
体育投注网址Guthold notes that the lack of those two possible solutions in some countries may be contributing to their exceptionally low physical activity levels.
In South Korea, for example, 97 percent of girls and 91 percent of boys didn’t get enough physical activity.
Guthold speculates that in such countries, those rates could be due to a strong focus on academic achievement at school at the expense of promoting physical activity.
She also points to the built-in environment in countries like South Korea with high urban density.
“Increased traffic and environments that are not safe for walking or cycling might be another explanation, particularly in big and growing cities,” Guthold said.
体育投注网址To really know how active kids are and how the factors around them affect that, we’d need more and better data, though.
That’s expensive, particularly in developing countries, but it can be done with tools like accelerometers and pedometers, Kahan says.
Then, instead of self-reported data, we’d have better information “so we know where we stand and what trends are and how much resources are needed.”
“This pandemic of inadequate physical activity is an aspect of modern life,” he said.
Technology makes physical activity less necessary, either for work or fun, and factors such as sprawl only add to that, Kahan says.
“It all sets the stage for physical activity, obesity, and diabetes pandemics,” he said.
