Abstract

Purpose

To examine predictors of exercise adherence in breast cancer survivors.

Methods

Seventy-five breast cancer survivors were randomly assigned to exercise (n = 37) or usual care (n = 38). Demographic, prognostic, physiologic, and psychosocial information was collected at baseline and 6 months. The exercise goal was 30 min of exercise 5 days/week for 6 months.

Results

Women randomized to exercise participated in moderate-intensity recreational exercise for 123 ± 52 min/week (81% of the prescribed 150 min/week) over 6 months. Baseline variables associated with better adherence were lower body mass index (BMI), smaller waist circumference, higher amounts of physical activity 6 months prior to enrollment, being in the preparation vs. contemplation Stage of Change and higher FACT-B breast cancer subscale score. After adjusting for these variables, lower BMI and higher Stage of Change continued to be associated with better adherence (p < 0.05).

Conclusions

Future studies of exercise and breast cancer prognosis should target obese women for participation, as well as women just beginning to contemplate participation and its benefits after a cancer diagnosis.
