Mediterranean Diet Intervention Among Men at LBJ Hospital With Prostate Cancer

Mediterranean Diet Intervention Among Men at LBJ Hospital With Prostate Cancer

This study, we will build upon our prior work and test the feasibility of a Mediterranean diet intervention for medically underserved men with prostate cancer seen at LBJ Hospital, a large safety net facility in Harris County, TX.

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.

Inclusion Criteria:

• Histologically confirmed adenocarcinoma of the prostate that is localized based on metastatic workup ordered by the treating physician (which may include CT scan, bone scan, MRI and/or other imaging). Note that metastatic workup is not required for enrollment.
• Diagnosis within 12 months prior to enrollment OR
• Currently managed on active surveillance, with initial biopsy being <5 years from date of enrollment
• Self-identified Hispanic and/or Black/African American
• Patient at LBJ Hospital

Exclusion Criteria:

• Special dietary requirements such that patient is unwilling to attempt dietary change
• Unwillingness to participate in study activities
• Inability to keep appointments
• Food allergy prohibitive of a Mediterranean diet, i.e. nuts allergy
