Descriptive statistics for predictor and outcome variables

Predictor variables
	Baseline	6 months^a
	Mean (SD)	Mean (SD)
BCPT Musculoskeletal	3.38 (2.29)	2.68 (2.14)
BCPT Vasomotor	2.19 (2.28)	1.58 (2.15)
BCPT Cognitive	2.56 (2.45)	1.84 (2.41)
SF-12 Physical	47.97 (7.68)	52.06 (7.21)
SF-12 Mental	52.36 (7.91)	54.14 (7.88)
Outcome variable
	Baseline	6 months^b	12 months	18 months^c
	Median (IQR) (N= 176)	Median (IQR) (N =176)	Median (IQR) (N=148)	Median (IQR) (N=142)
Bouted MVPA min/week	18.19 (59.28)	55.56 (163.69)	43.0 (129.50)	38.1 (119.25)

Note: BCPT = Breast Cancer Prevention Trial Symptom Checklist

MVPA = moderate to vigorous physical activity

Paired t tests indicated that all BCPT scales significantly decreased from baseline to 6 months (all p values < .01) and both SF-12 measures significantly improved (both p values =.01).

Mean bouted MVPA min/wk significantly increased from baseline to 6 months (p = .001)

Mean bouted MVPA min/wk significantly decreased from 6 months to 18 months (p = .001)
