Purpose/Objective(s): Diabetes remains one of the most common chronic diseases in the United States among older Americans, which while sensitive to lifestyle intervention such as dietary changes and exercise, can be difficult to control. Prior evidence has suggested that individuals with a diagnosis of cancer have more difficulty in managing their diabetes. This analysis aims to comprehensively explore the role of and timing of a prostate cancer diagnosis and its treatment to several diabetes management activities, including diet, exercise, and weight loss, in a large, nationally representative, cross-sectional study.

Materials/Methods: Our analysis used five cross sections from the publicly available National Health and Nutrition Evaluation Survey (NHANES) from 2001-2010. A sample of 87 diabetic or pre-diabetic men with a history of prostate cancer was matched to a comparison group of 132 men with elevated PSA but no reported diagnosis of prostate cancer. Outcomes of interest included HbA1c results, grams of sugar consumed daily, physical activity and body mass. Multivariate regression analyses were conducted to clarify the associations of a prostate cancer diagnosis with these outcomes. Treatment modality (prostatectomy or radiation therapy) was also considered. Demographic and socioeconomic factors, including education, race, income, and marital status, were controlled for in all models.

Results: The average age of prostate cancer patients in the sample was 71.4 years, who were diagnosed on average 6.8 years prior to the survey. On multivariate analysis, compared to controls, diabetics and pre-diabetics with newly diagnosed prostate cancer within 5 years of the survey consumed an average of 28 more grams of sugar daily (p<0.05). Prostate cancer patients had a body mass index that was 1.6 kg/m2 higher, on average, than that of controls (p<0.05). With regard to prostate cancer treatment modality, individuals who received both a prostatectomy were approximately 33% more likely to report being less physically active than peers. There was no association between prostate cancer diagnosis or treatment and Hemoglobin A1c.

Conclusion: Pre-diabetic and diabetic men with prostate cancer report fewer behaviors and outcomes consistent with optimal glycemic management including a higher BMI, less physical activity and higher sugar consumption. Interventions designed to improve diabetes awareness and self-management may be useful in this population.
