Americans getting more inactive, computers partly to blame

Americans are becoming increasingly sedentary, spending almost a third of their waking hours sitting down, and computer use is partly to blame, a new study found.

Over almost a decade, average daily sitting time increased by roughly an hour, to about eight hours for U.S. teens and almost 6 1/2 hours for adults, according to the researchers. That includes school and work hours, but leisure-time computer use among all ages increased too.

By 2016, at least half of American kids and adults spent an hour or more of leisure time daily using computers. The biggest 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.
