In 2016 only 26% of men, 19% of women, and 20% of adolescents report performing
sufficient physical activity defined as at least 150 minutes of moderate-intensity
aerobic (endurance) physical activity and two days per week of muscle-strengthening
(resistance) activity for adults and at least 60 minutes of moderate-intensity aerobic
physical activity and three days per week of muscle-strengthening activity for
youth.8 An estimated $117 billion in U.S. annual health care costs and about 10%
of premature mortality are associated with inadequate physical activity. Moving
more and sitting less will benefit everyone.
According to the 2015-2016 National Health and Nutrition Examination Survey
(NHANES), 25.7% of adults reported sitting for more than eight hours per day, and
44.6% were inactive. Among U.S. adults, average sitting time increased from
about five hours a day in 2007 to about six hours a day in 2016. The figure below,
reproduced from the 2018 Physical Activity Guidelines Advisory Committee
Scientific Report,12 shows that based on a standard of 150 minutes of moderate to
vigorous physical activity a week, half of Americans are still either inactive or insufficiently
Epidemiological studies indicate that sedentary behavior harms health. A systematic
review of 27 studies found that sedentary children and adolescents are more
likely to be obese and have unfavorable measures of blood pressure, total cholesterol,
self-esteem, social behavior, physical fitness, and academic achievement.
For adults, the study found “strong evidence of a relationship between sedentary
behavior and all-cause mortality, fatal and non-fatal cardiovascular disease (CVD),
type 2 diabetes, and metabolic syndrome.” In addition, there is moderate evidence
for increased incidence of ovarian, colon and endometrial cancers.
