Bowel Function by PA Guideline Categories
| BFI Scalea | Not Active weighted PA min = 0 /wk (n=190) |
Insufficiently Active weighted PA min =1–149/wk (n=145) |
Meeting Guidelines weighted PA min =150–299/wk (n=72) |
Above Guidelines weighted PA min ≥ 300/wk (n=150) |

Weighted PA min = “weighted physical activity minutes” calculated as moderate minutes/week + 2 × vigorous minutes/week
SE = Standard Error of regression coefficient
Higher BFI score denotes better function; Total BFI score range 14–70; Urgency/Soilage range 4–20; Frequency (defined only for anastomosis group) range 6–30; Dietary range 4–20
Predicted mean (SE) adjusted for age, years since surgery, income over $50,000 (Y/N), Charlson-Deyo score ≥ 2 (Y/N), and ostomy status (for analysis of women only)
p < 0.05 Trend across ordered weighted PA-minute categories
p < 0.01 compared to not active group
p < 0.05 compared to not active group
Exceeds minimally important difference (MID) compared to not active group (4.5 for Total Bowel Function, 1.3 for BFI Urgency/Soilage, 1.9 for BFI Frequency, and 1.3 for BFI Dietary)
Combined women with ostomy and anastomosis because contrasts with not active had consistent direction
