Colorectal Cancer Knowledge and Awareness Among University Students in a Caribbean Territory: a Cross-sectional Study.

introductionThe burden of colorectal cancer (CRC) has been on the rise globally over the last decade. Several studies point to the fact that there is a lack of knowledge and awareness for CRC which may be attributed to the increase in the burden over time. Therefore, we aimed to assess the level and predictors for knowledge of CRC and its risk factors.

methodsThis study was a cross-sectional study conducted on the student population of the University of the West Indies, St. Augustine Campus, Trinidad. We assessed CRC knowledge using scales examining their level of knowledge for CRC and its risk factors. Lifestyle behaviors (smoking, physical activity, dietary behaviors, and alcohol consumption) and perceived risk for developing CRC were also collected using a standard survey. Predictors for CRC knowledge were assessed using forward stepwise linear and logistic regression models.

resultsThe overall CRC knowledge was 54.740% ± 19.721%. Poor knowledge levels were seen among 36.23% while satisfactory/good knowledge was seen among 63.77%. Predictors of poor CRC knowledge were males (OR = 1.559; p = 0.003), frequent/excessive alcoholic drinkers (OR = 1.924; p = 0.029), and low physical activity (OR = 1.331; p = 0.042). Predictors of satisfactory/good CRC knowledge were those with higher scores for the prudent dietary pattern (OR = 0.893; p = 0.016), and compared with those who reported no risk, participants reporting low risk had an increased likelihood of obtaining good CRC knowledge scores (OR = 0.526; p = < 0.001) and high risk (0.310; p = < 0.001).

conclusionThe level of awareness/knowledge on CRC and its risk factors is low. Improvement of CRC awareness and healthy lifestyle campaigns among young adults is needed for the Caribbean region.
