Association between self-reported depression and screening colonoscopy participation.

The impact of depression on participation in screening colonoscopy is poorly characterized. This study attempts to understand this relationship by conducting a cross-sectional analysis on a nationally representative sample of adults aged 50 to 75 years without a history of colorectal cancer or inflammatory bowel disease from the 2009 Medical Expenditures Panel Survey. Multivariable analysis shows that the odds of having a current colonoscopy is 1.3 times higher for individuals with depression compared with those without depression (odds ratio = 1.3; 95% confidence interval = 1.1-1.7). These findings suggest that depression may not be a risk factor for underutilization of CRC screening.
