Americans sat an extra hour each day in 2016 compared to 2007. Total time spent sitting daily increased to 8.2 hours for adolescents and 6.4 hours for adults, with 59 to 65 per cent sitting while watching television or videos at least two hours a day. The proportion of people who used computers for one hour or more daily during leisure time increased by 13 per cent among children, 4 per cent among adolescents, and 21 per cent among adults.
