Colorectal Cancer Screening Among Adults in Zuni Pueblo: Factors Associated with FOBT and Colonoscopy Utilization

Although strategies to mitigate barriers to colorectal cancer (CRC) screening have proven successful in some parts of the US, few of these strategies have been studied in rural, American Indian communities that may exhibit unique culturally driven attitudes toward and knowledge of colorectal cancer and experience increased barriers to healthcare access. In this study, we describe the results of a survey among CRC screen-eligible members of Zuni Pueblo (N = 218) on an array of questions regarding CRC screening behaviors, knowledge, satisfaction with and access to healthcare services, social support for CRC screening, perceptions toward FOBT, and preference for evidence-based interventions or strategies for improving CRC screening rates. Results from the multivariable model suggest age, having a regular healthcare provider, and harboring fewer negative perceptions toward FOBT are key drivers of ever completing CRC screening. Respondents reported strong support for Community Guide-recommended interventions and strategies for increasing CRC screening for nearly all proposed interventions. Results confirm the need for multilevel, multicomponent interventions, with a particular focus on improving Zuni Pueblo community members' access to a regular source of care, improving knowledge of CRC risk factor, and addressing negative perceptions toward CRC screening. These results provide critical, community-specific insight into better understanding the drivers of low guideline-adherent screening rates and inform local healthcare providers and community leaders of context-specific strategies to improve CRC screening in Zuni Pueblo.
