Abstract
Objective: Colorectal cancer (CRC) is the most preventable cancer if adherence to its screening guidelines through compliance with physician recommendations are met. Lack of access to care is the most significant barrier which was decreased by the Affordable Care Act (ACA), that may influence healthcare behaviors/practices. The aim of this study was to determine the factors affecting compliance with recommendations for CRC screening between two US National Health Interview Surveys (NHIS) in 2010 and 2015. Methods: We used individual data of adults aged ≥50 years from the Cancer Module of NHIS that repeats every-5-years. Multiple logistic regression analyses were employed to identify the compliance associated factors and their changes after five years. Results: We included final data of 1,553 and 2259 and individual from 2010 and 2015, respectively. Overall, compliance to physician recommendations for colorectal cancer was 85.70% in 2010 and 81.54%. Men compiled more in 2010 than women which was reversed in 2015. The multivariable-adjusted odds of compliance were increased with age; lower for female [Odds ratio (OR)= 0.45 Confidence Interval (CI 95% 0.27, 0.75), having a family history of CRC [OR=3.05 CI:1.02, 9.05], having insurance [OR 3.58 CI:1.4, 9.12], and Odds increased with the number of doctor visit in 2010. However, in 2015 the odds were substantially increased with the increasing age, reversed odds for female [OR= 3.49 CI: 1.67, 7.29)], increased for non-Hispanic Blacks [OR= 4.87 CI: 2.05, 11.55] and lower for Asian [OR=0.33 CI:0.15, 0.74], higher for family history of colorectal cancer [OR=3.31 CI:1.92, 5.69]. Although insurance coverage and the number of doctor visits were significant predictors of compliance in 2010, those became non-significant in 2015. Conclusions: Compliance disparities by gender and access to healthcare either reduced in strength or reversed between 2010 and 2015. The non-Hispanic Black significantly higher in compliance than other race-ethnicities in 2015.
