Mediterranean Diet Intervention Among Men at LBJ Hospital With Prostate Cancer

Primary Objectives:

To determine the feasibility of a Mediterranean diet-based intervention adapted for underrepresented minority men with prostate cancer, defined based on the following process measures68:

• Enrollment (completion of 25 patient accrual within 2 years)
• Retention (completion of the study through the 6-month time point, with ≥80% defined as successful)
• Adherence (the percentage of completed study sessions and clinic visits, with ≥70% considered successful).

Secondary Objectives:

To determine changes due to the Mediterranean diet intervention in the following measures:

• Mediterranean diet score (define using MEPA I calculated using VioScreen data)
• Weight/BMI
• QoL (EQ-5D-5L)
• Physical activity (IPAS)
• Non-invasive biomarkers
• Gut microbiome
• Metabolomics

To determine fidelity of intervention,62 including a description of patient comprehension, cognitive skills and perceived ability to change diet during the intervention.
