Unweighted counts. Respondents with missing data on demographic characteristics (n = 10,169) or physical activity (n = 52,887) were excluded from the analysis.
Weighted prevalence of reporting at least 1 activity occurring in short bouts (<10 minutes). Respondents reported 2 types of nonoccupational physical activities or exercises, such as running, calisthenics, golf, gardening, or walking that they spent the most time doing in the past month. For each reported activity, frequency and bout duration were assessed by using the following questions: “How many times per week or per month did you take part in this activity during the past month?” and “When you took part in this activity, for how many minutes or hours did you usually keep at it?” Respondents who reported a bout duration of 1 to 9 minutes for either activity were categorized as reporting a short bout of physical activity.
Corrected Pearson χ2 tests were used to examine differences across categories of demographic characteristics.
