Post-diagnosis physical activity was reported, on average, 6 months after diagnosis
All analyses in Table 2 are weighted or adjusted to take into account sampling
Total includes all races
To calculate total METs, MET values of 4.0 and 8.0 were assigned to moderate- and vigorous-intensity activity, were multiplied by reported number of hours per week for each activity type and then were summed
To evaluate change between pre- and post-diagnosis activity, the categorical variable was defined as follows: Increased: increased activity by ≥ 30 minutes compared to pre-diagnosis amount; Decreased: decreased activity by ≥ 30 minutes; No change: reported activity levels at post-diagnosis were within 30 minutes of pre-diagnosis levels
Sedentary = No activity reported; Insufficiently active >0 minutes but < 150 minutes of activity per week; Sufficiently active ≥ 150 minutes of activity per week
