Scripted tours through a giant inflatable colon: An innovative and effective educational tool in urban communities

Effect of an Inflatable Colon on Colorectal Cancer Knowledge and Screening Intent Among Male Attendees at State Fairs in Two Midwestern States, 2023

Introduction

Colorectal cancer (CRC) is the third most-diagnosed cancer among men and women in the US. This study aimed to evaluate the influence of an interactive inflatable colon exhibit on CRC knowledge and screening intent among men attending state fairs in 2 midwestern states.

Methods

At the 2023 state fairs in 2 midwestern states, eligible participants (men aged 18-75 y who could speak and read English and resided in 1 of the 2 states) completed a presurvey, an unguided tour of the inflatable Super Colon, and a postsurvey. Primary outcomes were changes in knowledge (actual and perceived) and CRC screening intent from presurvey to postsurvey. We used χ2 tests to examine differences in survey results between the 2 sites and the association between demographic characteristics and behaviors (knowledge and intentions) before entering the Super Colon exhibit. We used the McNemar test to examine differences in presurvey to postsurvey distributions.

Results

The study sample (N = 940) comprised 572 men at site A (60.8%) and 368 men at site B (39.2%). Except for 1 question, baseline CRC knowledge was relatively high. Greater perceived knowledge was inversely associated with greater actual knowledge. After touring the Super Colon, participants improved their actual knowledge of CRC prevention and self-perceived CRC knowledge. Most participants (95.4%) agreed that the Super Colon was effective for teaching people about CRC.

Conclusion

These findings emphasize the role of community-based educational initiatives in encouraging CRC screening uptake and increasing research participation among men and affirm that the inflatable colon is as an effective educational tool for increasing CRC knowledge and encouraging early-detection screening behavior among men.

Educational interventions to improve bowel cancer awareness and screening in Organisation for Economic Co-operation and Development countries: A scoping review

Objectives

Summarise theory informed educational interventions for improving bowel cancer awareness and screening.

Methods

A search was conducted in PubMed, EMBASE, Web of Science and CINAHL. English studies from 2016 to 2022 which implemented community-based bowel cancer awareness and/or screening education interventions for adults in Organisation for Economic Co-operation and Development countries were included.

Results

Sixty-two studies were included, 32 measured both screening and awareness (24 measured screening only, 6 measured awareness only). Education interventions were grouped and summarised in five education types: lay community health education/counselling (n = 28), education material (n = 5), health professional education/counselling (n = 10), mass media (n = 5) and other (n = 19). Other included education interventions which did not fit into the four types previously mentioned. Six studies tested more than one education type. Each type within these studies were reported/summarised separately within the appropriate education type. Lay educators resulted in improved awareness and screening. Brochures were effective education materials for screening and combined with lay educators resulted in increased awareness. State-wide mass media campaigns significantly improved screening uptake for up to 2-months post-campaign. Fear and loss-framed messaging improved screening intentions compared to humour or gain-based messaging. Decision aids had limited improvements in awareness. Facebook campaign and telephone counselling had limited improvements in screening.

Conclusions

Lay community health educators, brochures, and mass media campaigns occurring multiple times a year may be effective interventions in improving screening and/or awareness. Such approaches should be considered when developing community education. Education interventions should include multiple components suggested above to maximise improvements of awareness and screening.

Changes in colorectal cancer knowledge and screening intention among Ohio African American and Appalachian participants: The screen to save initiative

African Americans and Appalachians experience greater incidence and mortality rates of colorectal cancer due to factors, such as reduced prevalence of screening. An educational session (the Screen to Save Initiative) was conducted to increase intent to screen for colorectal cancer among African Americans and Appalachians in Ohio. Using a community-based approach, from April to September 2017, 85 eligible participants were recruited in Franklin County and Appalachia Ohio. Participants completed a knowledge assessment on colorectal cancer before and after participating in either an educational PowerPoint session or a guided tour through an Inflatable Colon. Logistic regression models were used to determine what factors were associated with changes in colorectal cancer knowledge and intent to screen for colorectal cancer. The majority (71.79%) of participants gained knowledge about colorectal cancer after the intervention. Multivariate results showed that race (OR = 0.30; 95% CI: 0.11–0.80 for African Americans versus White participants) and intervention type (OR = 5.97; 95% CI: 1.94–18.43 for PowerPoint versus Inflatable Colon) were associated with a change in knowledge. The association between education and intent to screen was marginally statistically significant (OR = 0.42; 95% CI: 0.16–1.13 for college graduate versus not a college graduate). A change in colorectal cancer knowledge was not associated with intent to screen. Future educational interventions should be modified to increase intent to screen and screening for colorectal cancer. Further research with these modified interventions should aim to reduce disparities in CRC among underserved populations while listening to the voices of the communities.
