Summary
Nearly half of adults aged 50+ in nonurban Minnesota were not adherent to colorectal cancer (CRC) screening guidelines. This study assessed adherence across four CRC screening methods, highlighting significant gaps in screening.
Area of Science:
- Public Health
- Epidemiology
- Cancer Prevention
Background:
- Colorectal cancer (CRC) screening is crucial for early detection and prevention.
- Adherence to CRC screening guidelines remains a public health challenge, particularly in nonurban populations.
Purpose of the Study:
- To determine the self-reported colorectal cancer screening adherence rates among adults aged 50 years and older in five nonurban Minnesota counties.
- To assess adherence across all four recommended CRC screening modalities.
Main Methods:
- A survey was administered in 2000 to 1693 randomly selected adults aged 50+.
- The survey assessed adherence to fecal occult blood test, flexible sigmoidoscopy, colonoscopy, and barium enema.
- Nonresponse was adjusted using Horvitz-Thompson weighting.
Main Results:
- Overall adherence to any CRC screening method was 55.3%.
- Specific modality adherence rates were: fecal occult blood test (24.5%), flexible sigmoidoscopy (33.8%), colonoscopy (29.3%), and barium enema (13.7%).
- 44.7% of respondents were not adherent to recommended CRC screening guidelines.
Conclusions:
- Nearly half of the target population remained unscreened by any CRC screening method.
- The study highlights the need for improved strategies to increase CRC screening adherence in nonurban areas.
- Assessing all four screening modalities provides a comprehensive understanding of adherence and nonadherence.
