Abstract Body:
Background: Guidelines of the American Cancer Society and US Preventive Services Task Force specify that colorectal cancer (CRC) screening using guaiac-based fecal occult blood test (FOBT)/fecal immunochemical test (FIT) should be done at home. We examined the prevalence and correlates of individuals who screen for CRC using FOBT/FIT, at home versus in a physician’s office. Methods: Analysis of 11,443 respondents, age 50-75 years, from the Cancer Controls Supplement of the National Health Interview Survey was conducted. Weighted multivariable logistic regression was used to identify the determinants of CRC screening using FOBT/FIT at home versus in-office.Results: Overall, 22.8% of respondents had CRC screening using FOBT/FIT, and among this screening population, the prevalence of in-office screening was 25% (95% CI, 22.7-27.4). In the multivariable model, age, geographic region, health insurance coverage status, and CRC risk factors predicted FOBT/FIT uptake, regardless of setting. When comparing in-office versus at-home screening, we found that sociodemographic factors alone, not CRC risk factors, predicted FOBT/FIT uptake. Hispanics had greater odds of utilizing in-office FOBT/FIT (aOR 1.61; 95% CI, 1.05-2.47). Compared to those who were 50 to 59 years of age, respondents age 60-69 years (aOR: 0.64, 95% CI: 0.49, 0.84) and 70-75 years (aOR: 0.48, 95% CI: 0.34, 0.67) were less likely to utilize in-office FOBT/FIT.Conclusion: This study identified high prevalence of in-office FOBT/FIT use, as well as differences in the uptake of CRC screening using FOBT/FIT, at home versus in-office. Our study highlights poor adherence of physicians to national guidelines.
