Role of Race in Nutritional Approach in Men on ADT

Description

There is a well-documented association between androgen deprivation therapy (ADT) and cardiovascular morbidity. A majority of men on ADT gain weight contributing to an increase in cardiovascular risk factors (CVRFs) and cardiovascular morbidity. Dietary intervention combined with exercise have shown success in reducing weight/fat mass and improving cardiovascular risk factors (CVRF). There is little data on whether African American men would respond to diet and exercise interventions differently from non-Hispanic white men. We will conduct a pilot, controlled two-phase intervention study stratified by race to investigate the following objectives: 1. Compare effect of a hypocaloric, anti-inflammatory diet on changes in fat mass between African- American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. 2. Compare effect of a hypocaloric, anti-inflammatory diet on changes in cardiovascular risk factors (body weight, lean body mass, waist-to-height ratio, blood pressure, lipids and HbA1C) and inflammatory markers (hs-CRP and cytokines) between African-American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. 3. Compare effect of a hypocaloric, anti-inflammatory diet on changes in cancer-related fatigue and quality of life between African-American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. We will enroll 35 African American and 35 non-Hispanic white men with prostate cancer undergoing ADT therapy. In phase 1, after baseline assessment, men will consume their habitual diet and continue their habitual activity level for 3 months. During phase 2, participants will be instructed to consume a hypocaloric (-500 kcal), anti- inflammatory diet and walk for 1 hour on 3 days per week for 3 months. At baseline, after phase 1 and 2 primary outcome (fat mass) and secondary outcomes (CVRF and inflammatory markers) and tertiary outcomes (cancer-related fatigue and quality of life) will be determined.
