Fruit and Vegetable Intake and Prostate Cancer Outcomes Among African American Men

摘要

This study was conducted to evaluate the impact of dietary behaviors, specifically fruit and vegetable consumption, on outcomes of prostate cancer (PC) among a random sample of African American (AA) men. The goal was to determine how fruit and vegetable behavior might enhance treatment outcomes and the quality of life among AA men. Currently it is unknown how culturally- specific dietary behaviors impact treatment outcomes for PC for AAs. The parent study was a four-year study, conducted through black churches located in Atlanta, GA, and maintained two specific aims: 1) to develop a multicomponent, culturally-sensitive nutrition intervention package (Tx) for AAs, and 2) to evaluate the feasibility and efficacy of the intervention. primary outcome variables for the study which included servings of fruit and vegetables (F & V), total fat and fiber intake, serum cholesterol and serum carotenoids. Given the small number of men who reported a history of being treated for PC (n = 2), we were not able to test the mediation impact of dietary practice on PC outcomes. However, as anticipated, those men who reported being treated for PC tended to be older, and to maintain lower blood pressure and levels of cholesterol. We were able to evaluate a profile of those men who were likely to get screened for PC compared to those who were not. Participants who had been screened for PC were approximately 12 years older, had a somewhat higher systolic blood pressure, level of cholesterol and body mass index (BMI). Fifry percent (50.6%) of respondents reported ever being screened for PC (Table 1). Of those reporting being screened for PC, 64.0% indicated having a PSA compared to 51.3% for those that had a DRE conducted.
