Distinguishing factors for asymptomatic colonoscopy screening

Area of Science:

• Oncology
• Preventive Medicine
• Health Services Research

Background:

• Colorectal cancer (CRC) remains a significant public health concern.
• Effective screening methods like colonoscopy are available but underutilized.
• Understanding factors influencing screening uptake is vital for public health strategies.

Purpose of the Study:

• To compare demographic, knowledge, belief, and barrier factors between individuals who underwent asymptomatic colonoscopy screening and those who did not.
• To identify key determinants associated with CRC screening adherence.

Main Methods:

• Cross-sectional study comparing two groups: asymptomatic colonoscopy screeners (n=100) and non-CRC screening individuals (n=142).
• Data collected on demographics, medical history, physician factors, knowledge, beliefs, and perceived barriers related to CRC screening.
• Statistical comparison between the two groups.

Main Results:

• Screeners were more likely to have lower income and education levels compared to non-screeners.
• Individuals who underwent screening demonstrated higher knowledge about colonoscopy purpose and perceived it as more normative.
• Screeners reported significantly fewer perceived barriers to undergoing colonoscopy.

Conclusions:

• Lower socioeconomic status and higher knowledge/normative beliefs are associated with CRC screening adherence.
• Perceived barriers significantly influence CRC screening decisions.
• Interventions should address knowledge gaps and reduce perceived barriers to improve CRC screening rates.
