Figure 3. Trends in the joint prevalence of high sitting time (>8 hours per day) and physical inactivity among US adults by domain of physical activity, NHANES 2007/2008 to 2017/2018.

Figure 3.

The blue line represents the percentage who reported both sitting for more than 8 hours per day and engaging in less than 10 minutes per week of leisure-time physical activity. The gray line represents the percentage who reported both sitting for more than 8 hours per day and engaging in less than 10 minutes per week of multi-domain (leisure-time, occupational/household, or transportation-related) physical activity. Error bars represent 95% confidence intervals.

From 2007/2008 to 2017/2018, a significant positive linear trend and negative quadratic trend (p<0.05) was observed for the joint prevalence of high sitting time and leisure time physical inactivity. From 2007/2008 to 2017/2018, a significant negative quadratic trend (p<0.05) was observed for the joint prevalence of high sitting time and multi-domain physical inactivity, with no significant linear trend.
