Association between diagnosed diabetes and self-reported cancer among U.S. adults: findings from the 2009 Behavioral Risk Factor Surveillance System.

Abstract

To assess the association between diagnosed diabetes and self-reported cancer among U.S. adults. We analyzed data for 397,783 adults who participated in the 2009 Behavioral Risk Factor Surveillance System and had valid data on diabetes and cancer. After adjustment for potential confounders, diabetic men had higher adjusted prevalence ratios for cancers of the prostate (1.1 [95% CI 1.0-1.3]), colon (1.3 [1.0-1.7]), pancreas (4.6 [1.8-11.7]), rectum (2.2 [1.0-4.7]), urinary bladder (1.7 [1.2-2.2]), and kidney (1.9 [1.2-3.0]) than nondiabetic men (all P < 0.05). Diabetic women had higher adjusted prevalence ratios for cancers of the breast (1.1 [1.0-1.3]) and endometrium (1.6 [1.2-2.0]), and leukemia (2.3 [1.3-4.2]) than nondiabetic women (all P < 0.05). Our results suggest that diabetic adults have higher prevalences of certain cancers than nondiabetic adults.
