Factors Affecting Adherence to National Colorectal Cancer Screening: A 12-Year Longitudinal Study Using...

Area of Science:

• Public Health
• Epidemiology
• Cancer Prevention

Background:

• Consistent colorectal cancer (CRC) screening is crucial for reducing advanced-stage CRC incidence and mortality.
• Early detection through screening significantly improves patient survival rates.

Purpose of the Study:

• To identify socioeconomic, familial, and medical factors influencing CRC screening compliance in Korean adults.
• To analyze longitudinal data for a comprehensive understanding of screening adherence patterns.

Main Methods:

• A 12-year longitudinal study (2007-2018) of 3,464 Korean adults aged 50-79.
• Utilized linked data from national health surveys and insurance services.
• Employed ordinal logistic regression to analyze adherence levels (nonadherent, intermittently adherent, consistently adherent).

Main Results:

• Consistent CRC screening was positively associated with income (100-150% category), clerical/sales/service jobs, and medium-sized city residency.
• Higher education (high-school graduation), married status, and employment-based/private insurance use correlated with increased screening adherence.
• No disability, family history of CRC, and prior colorectal neoplasm history also significantly predicted consistent screening uptake.

Conclusions:

• Low regular participation in CRC screening in South Korea necessitates targeted interventions.
• Policies should prioritize enhanced educational and public relations efforts to boost screening rates.
