In comparison to the United States, Maryland is facing a significantly higher burden of colorectal cancer incidence and mortality. The primary objective of this study was to determine the predictors of colorectal cancer screening use in Maryland.


We performed secondary analyses on Maryland Cancer Survey 2002 data from 2994 respondents to investigate important predictors for individual colorectal cancer screening tests. CRC screening outcomes were defined as (1) FOBT within the past year, (2) sigmoidoscopy within the past 5 years, or (3) colonoscopy within the past 10 years.


We found that clinician recommendation for a screening test is the best predictor in both age categories (50-64 years and 65+ years); it is a very strong indicator and consistently improves the odds of use by a factor of at least 8 for any screening test.


There remains a great need for improved colorectal cancer screening in Maryland. According to our results, it is clear that the most influential way to improve overall colorectal cancer screening for each test and both age groups is to increase clinician recommendation for these tests.
