Background: Black Americans have the greatest colorectal cancer (CRC) incidence and mortality rates in the United States. Suboptimal CRC screening rates may be mediated by health literacy, a lack of knowledge about the screening benefits and influenced by health services factors. We examined the relationship between CRC risk perceptions and socio-demographic characteristics, disease prevention activities, and personal/family history of CRC among Black men.

Methods: The cross-sectional survey used a self-administered questionnaire and was conducted in five cities in the State of Florida between April 2008 and October 2009. Of the total 425 participants, 331 responses were valid for analysis. Descriptive statistics and logistic regression were performed.

Results: Of 331 participants, higher CRC risk perceptions were exhibited among those aged ≥60 years (70.5%) and American nativity (59.1%). Multivariate analyses found men aged ≥60 had three times greater odds of having higher CRC risk perceptions compared to those ≤ 49 years. Obese participants had more than four times the odds and over-weight subjects had more than twice the odds as compared to healthy weight/underweight participants, to have higher CRC risk perceptions. Men with a personal/family history of CRC also had greater odds of having higher CRC risk perceptions (OR = 9.18; 95% CI = 2.02-41.79).

Conclusion: Given early-onset of CRC in Black men, community educational programs tailored to Black men are needed to improve CRC screening uptake. This information will inform culturally resonate health promotion interventions to elevate CRC risk perceptions and increase screening in Black men.
