Here's some news you shouldn't take sitting down: since the release of national physical activity (PA) guidelines in 2008, Americans haven't really made a dent in improving PA rates, while "significantly" increasing the amount of time spent on sedentary behavior. Those findings were the major revelations from a first-of-its-kind study that factored work, leisure-time, and transportation-related PA (most PA studies have focused on leisure-time activity only).
The study, published in JAMA Network Open, analyzed results from 27,343 adults who participated in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016. Researchers wanted to find out what percentage of Americans met the US Department of Health and Human Services' activity guidelines, and how that rate may have changed since the release of the guidelines in 2008. Those guidelines, updated in 2018, recommend at least 150 minutes per week of moderate-intensity PA or 75 minutes of vigorous PA (or an equivalent combination of both).
What they found wasn't encouraging. Over the 10-year study period, the percentage of Americans who reported meeting the PA guidelines remained nearly flat—from 63.2% in 2007-2008 to 65.2% in 2015-2016.
Even worse, researchers noted a significant increase in sedentary behavior over the same time period, from 5.7 hours per day in 2007-2008 to 6.4 hours per day in 2015-2016. The increase was recorded in nearly every demographic subgroup in the study, and was highest among individuals with college-or-higher educations and individuals who are obese.
