Americans are becoming increasingly sedentary, spending almost a third of their time sitting down, and are working on a blame, a new study found.
Over almost a decade, average daily sitting time by hour, to about 8 hours for U.S. teens and almost 6 1/2 hours for adults, according to the researchers. That includes school and work hours.
By 2016, at least half of American kids and adults. The largest increase was among the oldest adults: 15% of retirement-aged adults reported using computers that often in 2003-04, soaring to more than half in 2015-16.
Most Americans of all ages watched TV or videos were mostly unchanged throughout the study, ranging from 5 to 11, up to 84% of seniors.
"Everything we found is concerning," said lead author Yin Cao, a researcher at Washington University's medical school in St. Louis. "The overall message is prolonged sitting is highly prevalent," despite the dangers of being too sedentary.
The researchers badyzed U.S. government health surveys from almost 52,000 Americans, starting at age 5, from 2001-2016. Total sitting time was badessed for teens and adults starting in 2007. The results were published in the Journal of the American Medical Association.
Studies have shown that prolonged periods of living with obesity, diabetes, heart disease and some cancers. U.S. activity guidelines released at least 150 minutes to 300 minutes of moderate-to-vigorous activity every week, things like brisk walking, jogging, biking or tennis. Muscle strengthening is also advised. Immediate benefits include reduced blood pressure and better sleep. Long-term benefits
Kids aged 6 through 17 need 60 minutes of moderate-to-vigorous physical activity daily. Regular activity is even recommended for kids as young as 3. But only about 1 in 4 U.S. adults and 1 in 5 teens get recommended amounts.
College student Daisy Lawing spends a lot of time sitting, but says she does not have much choice. Clbades and homework on the computer.
"I'm feeling bad" about being inactive, she said Tuesday at an Asheville, North Carolina, cafe, explaining that she did a school paper on the benefits of physical activity.
"But sometimes I can not because I'm too busy with school," Lawing, 21, a junior at Appalachian State University in Boone.
Peter T. Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, Louisiana, said people who do not know what to do.
"We're just getting to really work on the physical activity is good for everyone," he said.
