Colorectal cancer screening in 3 racial groups

Area of Science:

• Oncology
• Public Health
• Health Disparities

Background:

• Colorectal cancer (CRC) incidence and mortality rates vary significantly across racial and ethnic groups in the United States.
• Understanding the factors influencing CRC screening adherence is critical for reducing cancer-related health disparities.

Purpose of the Study:

• To identify predictors of adherence to colorectal cancer (CRC) screening guidelines.
• To examine these predictors across diverse racial and ethnic groups, including African Americans, European Americans, and Native Americans.

Main Methods:

• A survey was administered to assess participants' knowledge, beliefs, and behaviors concerning CRC screening.
• Predictive regression modeling was employed to analyze the factors associated with CRC screening.

Main Results:

• CRC screening rates did not significantly differ by race.
• Key predictors for screening adherence included being male, receiving a physician's recommendation, having a history of polyps or tumors, being under 70 years old, possessing greater CRC knowledge, and experiencing fewer barriers to screening.

Conclusions:

• Race was not found to be a significant predictor of CRC screening adherence.
• Knowledge, perceived barriers, and physician recommendation are vital factors influencing CRC screening across all racial groups.
• Interventions aimed at increasing CRC screening should focus on these modifiable factors.
