What is a significant factor affecting colorectal cancer screening rates?

Education and income level significantly influence colorectal cancer screening rates because individuals with higher levels of education often possess better health literacy and are more likely to understand the importance of preventive screenings. They may also be more aware of the available resources and recommended guidelines regarding screening. Additionally, income level can directly affect one's ability to afford healthcare services, including screening tests, as well as impact one’s access to insurance coverage that facilitates such screenings.

Factors such as gender and age are relevant but less impactful when compared to education and income, as these demographics do not necessarily correlate with an individual's understanding or access to screening opportunities. Ethnicity and geographic location can influence health disparities and access to care, but education and income more universally affect these barriers across different populations. Access to healthcare facilities is critical, but without the underlying education and income support that drive individuals to seek out these screenings, merely providing access may not be sufficient to increase screening rates.
