Area of Science:

  • Public Health
  • Health Disparities
  • Preventive Medicine

Background:

  • Colorectal cancer (CRC) screening is recommended for individuals 50 and older to reduce mortality.
  • Despite recommendations, CRC screening rates remain low.

Purpose of the Study:

  • To assess attitudes and practices regarding CRC screening among Black and White men and women aged 50-79 in Genesee County, Michigan.
  • To identify barriers and motivators for CRC screening adherence.

Main Methods:

  • Telephone interviews using random digit dialing with 355 participants.
  • The Health Belief Model framework was used to assess attitudes and practices.

Main Results:

  • Whites showed higher awareness of endoscopic screening procedures compared to Blacks.

  • Fewer than 30% of all respondents adhered to CRC screening guidelines.
  • Black females had the lowest adherence rates for fecal occult blood test (21%), flexible sigmoidoscopy (20%), and colonoscopy (12%).
  • Physician recommendation was a significant motivator; perceived need and embarrassment were key barriers.

    • Conclusions:

    • Interventions targeting both physicians and patients are crucial for increasing CRC screening rates.
    • Physician-guided promotion addressing identified barriers can improve CRC survival rates.
