Prostate 8 Study: A Pilot Randomized Controlled Trial (Rct) Of A Web-Based Lifestyle Intervention Versus Control Group Among Men With Prostate Cancer.

105Background: Lifestyle behaviors may reduce risk of prostate cancer progression. Guidelines and tools to support lifestyle modification are needed to improve prostate cancer care. Methods: We conducted a 12-week RCT among 73 men with clinical stage T1-T3a prostate cancer to determine if a lifestyle intervention that included a responsive website, Fitbits, and text messaging helps men adopt 8 healthy lifestyle behaviors (vigorous activity, not smoking, and 6 diet factors) compared to a control group. Eligible men had no contra-indications to aerobic exercise, Internet access, and engaged in ≤4 of the targeted 8 habits at baseline. We explored the efficacy of the intervention (n = 32) vs. control (n = 32) on behavior change via a lifestyle survey, 7 days of ActiGraph GT3X+ accelerometer data, and the Prostate 8 (P8) score (8 self-reported behaviors assigned 0 or 1 point, range 0-8). Results: Baseline characteristics were similar between arms. The median baseline P8 score was 3 in each arm. 12-week assessm...
