The ENGAGE (efficacy of a referral and physical activity program for survivors of prostate cancer) study established that a clinician referral and 12-week exercise training program increased vigorous physical activity at 12 weeks among men with prostate cancer. Here, we report the 6- and 12-month outcomes.
In this multicenter cluster randomized controlled trial, we compared a clinician referral and exercise training program to usual care. Discounted gym membership was offered to men in the intervention condition on completion of the 12-week exercise program. Self-reported physical activity at 6 and 12 months was the primary outcome. Quality of life, anxiety, and depressive symptoms were secondary outcomes.
A total of 147 men meeting eligibility criteria agreed to participate (54 intervention, 93 control). A positive interaction effect for vigorous physical activity was observed at 6 months, but not 12 months. No significant effects for the secondary outcomes were found.
A clinician referral and community-based supervised and unsupervised exercise training program, along with discounted gym membership, had a positive short-term effect on vigorous physical activity levels, but did not improve quality of life, in men with prostate cancer.
