Background: Colorectal cancer is one of the most important and most common cancers and thesecond leading cause of cancer deaths worldwide.Every year, nearly 1million new cases of colorectalcancer are recognized around the world and nearly half of them lose their lives due to the disease.Thestatistics reveal shocking incidence and mortality from colorectal cancer, therefore secondaryprevention of this cancer is important and research has shown that by early diagnosis 90% of patientscan be treated.Among the colorectal cancer screening tests, fecal occult blood test(FOBT)takes thepriority because of its convenience and also low cost. But due to various reasons, the participation ofpeople in this screening test is low. The goal of this study is to assess the factors that affect participationof population at average risk in colorectal cancer screening programs, based on health belief modelstructures. Materials and Methods: A cross‑sectional survey of 196 individuals, more than 50 yearsold, was conducted in Isfahan. Ninety‑eight people of the target group were selected from laboratorieswhile they came there for doing FOBT test; the method of sampling in this group was random sampling.The method of data collection in the other 98 individuals was by home interview and they were selectedby cluster sampling. The questionnaire used was based on health belief model to assess the factorsassociated with performing FOBT. The data collected were analyzed using descriptive and inferentialstatistical methods. Results: The mean score of knowledge in the first group was 48/5 ± 11/7 and inthe second group was 36/5 ± 19/3. Individuals in the first group were more likely to be married, hadmore years of schooling, and better financial status. There were significant relationships betweenknowledge (P<0.001), perceived susceptibility (P<0.001), perceived severity (P<0.001), perceivedbarriers (P<0.001), and self‑efficacy (P<0.001) in the two groups. There was no significant associationbetween the perceived benefits in the two groups. Those people who have had FOBT test in lastyear in each group reported better score of Health Belief Model model structures. Conclusion:According to this study, it seems that there is an urgent need to pay more attention to this diseaseand its prevention through screening. With a better understanding of factors affecting the test, it canbe a useful step to reduce the rate of death and costs, and improve the community health outcomes.
