Barriers to Endoscopic Colorectal Cancer Screening: Are Women Different from Men?

OBJECTIVES: The goals of this study were to compare women and men's understanding of screening flexible sigmoidoscopy (FS) and to identify predictors of endoscopic colorectal cancer (CRC) screening. METHODS: We mailed a 36-item questionnaire to asymptomatic patients aged 50 years or older who were scheduled for routine health assessments at a large multispecialty health-care group. Data collection included demographics, health behaviors, psychosocial factors, and CRC screening compliance. We followed participants for 1 year and assessed completion of endoscopic CRC screening. Both cross-sectional results examining previous screening and prospective results examining screening 1 year later were evaluated. RESULTS: 554 (54%) of 998 patients responded to the survey. Responses of 13 patients were excluded in the analyses due to unverifiable screening outcome. The majority of the respondents were white, and their average age was 62 years. Women reported significantly more embarrassment and fear about having FS than men. Women were more willing to consider having a FS if a female endoscopist performed the procedure. Of the 334 participants who were eligible to have endoscopic CRC screening, 53 (16%) had the procedure within a year. The odds of having the endoscopic procedures increased with the length of time the patients were under the care of their primary care providers and how strongly patients believed that one should have an FS even without symptoms. CONCLUSION: Our findings suggest some unique gender-specific attitudes and beliefs that act as potential barriers for CRC screening and further support the important role of primary care providers in facilitating timely completion of screening.
