Trends in physical activity and sedentary time among U.S. adults with diabetes: 2007–2020

Abstract

AimsTo examine temporal trends in physical activity and sedentary time among U.S. adults with diabetes from 2007 to 2020. MethodsWe performed serial cross-sectional analyses for participants aged ≥ 20 years with diagnosed diabetes from the U.S. National Health and Nutrition Examination Survey from 2007 to 2020. Participants completed the Global Physical Activity Questionnaire. ResultsThe analytic sample comprised 5096 adults with diabetes (mean age: 60.3 years; 48.2% females; 60.1% White people; mean body mass index: 33.0 kg/m2). From 2007-2008 through 2017–March 2020, the proportion of being physically sufficiently active increased from 41.5% (95% CI, 35.9%–47.2%) to 55.8% (95% CI, 51.3%–60.3%) (P-trend<0.001), whereas that of physical inactivity declined from 43.7% (95% CI, 38.1%–49.2%) to 31.0% (95% CI, 27.7%–34.3%) (P-trend<0.001). The decline was driven by increasing engagement in work-related and leisure-time activity. However, engagement in transportation-related activity stayed persistently low (16.7% [95% CI, 14.8%–18.8%] in 2017–March 2020) (P-trend = 0.25), and the mean daily sitting hours remained unaltered (6.2 [95% CI, 5.9–6.5] in 2017–March 2020) (P-trend = 0.60). Adults who were middle-aged or older, or with class III obesity, cardiovascular or chronic kidney concomitants were less likely to be sufficiently active and prone to prolonged sitting. ConclusionsPhysical activity levels in U.S. adults with diabetes have increased from 2007 to 2020, but about one in two remains inactive or insufficiently active. Sedentary time has not decreased. For diabetes management, nationwide efforts are needed to promote transportation-related physical activity while minimizing prolonged sitting, especially among those who are middle-aged or older, or with severe obesity or other complications.
