The research evaluated the impact of an inflatable colon exhibit on colorectal cancer (CRC) knowledge and screening intentions among 940 men at two state fairs in the Midwest in 2023. Using an observational cohort design, participants completed a presurvey, walked through the inflatable colon, and then completed a postsurvey. The surveys assessed changes in both actual and perceived knowledge of CRC and intentions to undergo screening. Results revealed a notable improvement in understanding key CRC concepts, such as the role of polyp removal in cancer prevention. Men over 45 had higher factual knowledge but lower perceived awareness. A majority (95.4%) found the exhibit to be an effective educational tool. The study concluded that community-based efforts, like the inflatable colon, are effective in boosting CRC knowledge and encouraging screening. It highlights the importance of using state fairs and similar events to reach underserved groups and promote early cancer detection.
