title: Socioeconomic Disparities in Colorectal Cancer Screening in Korea: A Nationwide Cross-Sectional Study.
abstract: Colorectal cancer (CRC) is a common cancer worldwide. The incidence and mortality rates of CRC are higher among lower socioeconomic status (SES) populations. We investigated the association between different indicators of SES and CRC screening rates in Korea. The eligible study population included males and females aged 50 to 74 years who participated in a nationwide cross-sectional survey (2010-2012). The "compliance with recommendation" category was applicable to participants who had undergone a fecal occult blood test (FOBT), double-contrast barium enema, or colonoscopy within 1, 5, or 10 years, respectively. In total, 6221 subjects (51.4% female, 55.6% aged 50 years) were included in the final analysis. Lower household income was significantly negatively related to compliance with screening recommendations (P for trend < 0.01) and marginally significantly related to noncompliance with recommendations (P for trend = 0.07). Older age and poor self-reported health were associated with the screening rate using the FOBT; male sex, older age, higher household income, having supplemental insurance, family history of cancer, and poor self-reported health were associated with a higher screening rate using colonoscopy. Lower household income was associated with a higher screening rate using the FOBT and with a lower screening rate using colonoscopy. To increase the rate of CRC screening using colonoscopy, efforts should be made toward improving the education and promotion of screening to the low household income target population.
