BACKGROUND  Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States.  Epidemiologic studies suggest that individuals diagnosed with type 2 diabetes mellitus (T2DM) are at 40% higher risk of CRC compared with non-diabetic individuals.  Given, the high risk of CRC among diabetic patients, CRC screening is important for early detection and treatment of CRC.  Limited evidences are available regarding CRC screening rate, and factors related to uptake and barrier to CRC screening among T2DM patients.

METHODS  We conducted a retrospective analysis of the Medical Expenditure Panel Survey (MEPS) 2011-2014.  Respondents aged 50-75 years diagnosed with T2DM were determined as being upto-date on CRC screening if they reported having had a blood stool test within the past year, sigmoidoscopy in the past five years, or colonoscopy in the past 10 years based on the 2016 US Preventive Services Task Force recommendation.  We used descriptive statistics to summarize the characteristics of T2DM patients by whether or not they were up-todate on CRC screening.  Multivariate logistic regression models were used to calculate adjusted odds ratios for likelihood of CRC screening uptake by comorbid conditions, health services utilization, and diabetes care learning source among individuals with T2DM.
