Ethnic minorities and women carry a disproportionate burden of colorectal cancer (CRC). Despite the effectiveness of colorectal screening, screening remains low among these populations. Physician recommendation is the strongest determining factor for cancer screening. A sample of 5733 screening eligible aged >=50, with a physician visit within 12 months was used. Underlying factors associated with unequal physician recommendations were examined using stepwise logistic regression.
Results: About 26% received an endoscopic screening recommendation. Likelihood of receiving a recommendation was lower for Hispanics and Blacks as compared with Whites in all ages and both genders, especially for women. Hispanics were 34% and Blacks 28% less likely to receive a recommendation compared to Whites. When controlling for annual income, the difference decreased to 23% for Hispanics and 17% for Blacks, although the difference remained significant. Controlling for education reduced it to 19% for Hispanics, 18% for Blacks and statistical significance was lost. Controlling for both education and income reduced the difference to 10% for Hispanics, 13% for Blacks. Multivariate adjustment diminished the difference to zero for Hispanics and Blacks to 3%. Controlling for insurance and regular source of care, the difference remained significant. When education was added to the control variables, the differences lost statistical significance.
Implication: Differences in screening can be explained through access to care and socioeconomic characteristics, especially education. Interventions to increase screening rates should therefore be targeted at increasing physician sensitivity to reduce unequal recommendations for women and the underserved.
