BackgroundAs life expectancy of men with prostate cancer (CaP)improves, the risks of chronic diseases and comorbid conditions become more relevant. Improving modifiable health behaviors now serves as a focus of guidelines to reduce all-cause morbidity and mortality from chronic disease among CaP survivors. Few studies have reported on these health behaviors in low-income, uninsured men with CaP MethodsIn addition to baseline demographic data, we collected four health behaviors in low-income men with CaP via telephone survey: physical activity, dietary intake of fruits and vegetables, weight management, and alcohol consumption. These behaviors were assessed for adherence to the American Cancer Society Prostate Cancer Survivorship Care Guidelines for health promotion. ResultsOf 236 participants, most self-identified as racial/ethnic minority (61% Hispanic, 16% Black). Most men demonstrated low (21%) or moderate (66%) adherence to guidelines, almost all of whom had poor adherence with recommendations for physical activity and fruit and vegetable intake. Multivariate analysis showed that non-white men were more likely to demonstrate low or moderate adherence. ConclusionsMost men in this cohort of low-income, uninsured CaP survivors did not engage the healthy behaviors promulgated by the American Cancer Society. Future interventions in this population should focus on encouraging and facilitating healthier lifestyle choices in physical activity, diet, and weight management.
