More than a third of U.S. adults ages 45 to 75 are not up to date on colorectal cancer screening, and people without a regular doctor are among the most likely to fall behind. That is the finding of a research letter in JAMA Network Open, published Oct. 19 by surgeons at The Ohio State University Wexner Medical Center and James Comprehensive Cancer Center in Columbus.
The team analyzed 2023 National Health Interview Survey data from 12,016 adults, representing about 95 million Americans. Overall, an estimated 34.5% were not up to date on screening. After adjusting for other factors, adults with no usual source of care had a 61% higher risk of being overdue, and uninsured adults had a 47% higher risk.
