Web-based Lifestyle Trial Among Men With Prostate Cancer: Prostate 8 (Prostate 8)

A Randomized Clinical Trial of Web-based Lifestyle Tools and Resources Versus Usual Care Among Men With Prostate Cancer

A randomized controlled trial of a technology-based lifestyle intervention vs. usual care among men with low-risk prostate cancer to determine the feasibility and acceptability of the intervention and the effect of the intervention on behavior change related to exercise, diet, and not smoking.

This is a PI-initiated, randomized, unblinded, clinical trial of a technology-based 3 month lifestyle intervention vs. usual care among men with low risk prostate cancer. We will recruit and consent 76 men with prostate cancer at UCSF. The subjects will be asked to complete questionnaires, 7 days accelerometer measurement, body measurements (weight, waist, hip, pulse, blood pressure) and collection of blood specimen at baseline and 3 months. Subjects will be randomized into two arms (Intervention Group and Control Group). The Intervention Group (N=38) will have access to the lifestyle website and an activity monitor (e.g., Fitbit), receive text messages, and be provided with individualized lifestyle recommendations. The Control Group (N=38) will have standard of care and be asked to continue with their usual lifestyle habits. They will receive access to the lifestyle website and be provided with individualized lifestyle recommendations at 3 months.

Men will receive a web-based, personalized lifestyle program. They will receive personalized prostate cancer-specific lifestyle recommendations on specific habits based on their eligibility survey responses. They will have access to the website composed of four topic areas (get active, eat well, stop smoking, and find support), receive a Fitbit and access to a Fitbit account and community group, and receive text messages and refrigerator magnet to reinforce behaviors. The website will be updated frequently with new tips and material and two weekly blogs will be maintained. Final content is reviewed by study investigators and patient advocates. Men will complete an intervention acceptability survey (acceptability of the website and intervention components) at 3 months.

Men randomized to the control group will receive standard of care. They will receive access to the website and personalized lifestyle recommendations on the 8 healthy habits targeted in the study after the 3 month trial.

Patients will have access to the lifestyle website and an activity monitor (e.g., Fitbit), receive texts, and be provided with individualized lifestyle recommendations.

We will measure the number of days the Fitbit was used during the study period in the intervention arm only to assess study feasibility

We will measure the number of text messages responded to that required a reply in the intervention arm only during the study period to assess study feasibility

We will measure the total number of days the website was visited in the intervention arm only during the study period to assess study feasibility

We will measure the total number of website visits in the intervention arm only during the study period to assess study feasibility

Memorial Anxiety Scale for Prostate Cancer and State Anxiety completed at baseline and 3 months. Trait anxiety completed at baseline.

Expanded Prostate Cancer Index Composite-26 and Short Form Health Survey-36 completed at baseline and 3 months.
