RT Journal A1 Shah J, Gupta S, Rockey DC T1 COlonoscopy screening in black and white patients JF JAMA JO JAMA YR 2009 FD February 25 VO 301 IS 8 SP 827 OP 829 DO 10.1001/jama.2009.164 UL http://dx.doi.org/10.1001/jama.2009.164 AB Black individuals represented only 6.4% of the population studied. In contrast, black persons represent 13.4% of the US population.2 This raises the possibility of bias in the population examined, particularly if black individuals who underwent screening were at elevated risk for colorectal cancer or polyps compared with the general black population. Additionally, although the data were obtained from a national endoscopic database, the underrepresentation of black persons raises concern that they may not be receiving colon cancer screening in adequate numbers compared with white individuals. This leads to the question of what is different about the small number of black individuals who chose to have a colonoscopy vs those who did not. These issues are critical to both the interpretation of the findings of this study and to future policies regarding tailored colorectal cancer screening.
