Colorectal Cancer Awareness and Beliefs in Malaysia: A Population-Based Survey

Abstract

Background: Colorectal cancer (CRC) is the third most common cancer and the fourth major cause of cancer deaths globally; in Malaysia, CRC is the second most common cancer in both males and females. Low awareness of cancer delays help-seeking and contributes to late presentation, poor detection and survival. Aim: We aim to investigate the level of colorectal cancer awareness and beliefs among the Gombak district population of Malaysia as part of a larger study designed to evaluate a cancer awareness-raising campaign. Methods: A survey of colorectal cancer awareness was conducted in Rawang (Gombak district, Selangor) between January and March 2018. This district is representative of a mix of ethnicities, age groups, education levels and income groups. A total of 4000 households were selected randomly from a list of all households by the Government Department of Statistics Malaysia to attain a sample size of 730 adults as indicated by our power calculation and taking potential refusals into account. Trained enumerators randomly selected eligible adults aged over 40 years old from each household and conducted an interview that included sociodemographic information as well as the Bowel Cancer Awareness Measure (CAM), the Attitudes and Beliefs about Cancer questionnaire (ABC) and the Champion Health Belief Model Scale (CHBMS) which were validated in Malaysia. Results: Data collection for this part of the larger study was completed in March. Currently, we are cleaning and entering the survey data into a database in preparation for statistical analysis including χ2 tests of association and logistic regression. The results of the analysis will be presented at the conference. Conclusion: This analysis will provide the first profile of awareness and beliefs about colorectal cancer among the Gombak district population of Malaysia.
