G: Association between diagnosed diabetes and self-reported cancer among U.S. adults: findings from the 2009 Behavioral Risk Factor Surveillance System. Diabetes Care 2011

OBJECTIVE—To assess the association between diagnosed diabetes and self-reported cancer among U.S. adults. RESEARCH DESIGN AND METHODS—We analyzed data for 397,783 adults who participated in the 2009 Behavioral Risk Factor Surveillance System and had valid data on di-abetes and cancer. RESULTS—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). CONCLUSIONS—Our results suggest that diabetic adults have higher prevalences of certain cancers than nondiabetic adults. Diabetes Care 34:1365–1368, 2011 D iabetes and cancer are two commonchronic diseases that exert seriousadverse effects on public health in the U.S. Approximately 25.6million adults (11.3%) aged 20 years or older were es-timated to have diabetes in 2010 (1). Ap-proximately 11.7 million Americans were living with cancer in 2007. Studies have found that diabetes is associated with an increased risk for certain types of cancer (2,3), and diabetes may increase the risk of all-cause mortality among people with cancer (4). To compare the prevalence of cancer between adults without and with diabetes, we analyzed a large population– based sample from the Centers for Diseas
