Do you feel confident navigating health screenings like cancer checks without having a regular doctor?

A recent analysis of 2023 survey data indicates that 34.5% of U.S. adults ages 45 to 75 are not up to date on recommended colorectal cancer screenings. This gap in preventive care is significantly more pronounced among individuals who lack a consistent primary healthcare provider or health insurance.

Why it matters

The U.S. Preventive Services Task Force recommends regular screening for adults between 45 and 75, as early detection of colorectal cancer is vital for effective treatment. This research underscores that structural barriers to accessing care are major drivers of delayed screening, potentially impacting long-term health outcomes for millions of adults.

This cross-sectional study of 12,016 adults across the U.S. found that 34.5% of the population aged 45 to 75 remains overdue for colorectal cancer screening. The findings highlight a 61% increased risk of missing screening for those without a usual source of care, though the study relies on self-reported data.

An independent, volunteer panel of national experts that provides evidence-based recommendations about clinical preventive services.

JAMA Network Open

A peer-reviewed medical journal that publishes research on clinical care and public health.

The details

Researchers analyzed 2023 National Health Interview Survey data to understand how systemic access to medical care influences preventive health. They found that 71.6% of U.S.-born adults without a regular doctor were overdue for screening, compared to 30.6% of those who have a established provider. Additionally, being uninsured was linked to a 47% higher risk of being overdue, while recent immigrants to the U.S. faced a 25% higher risk of screening delays compared to U.S.-born adults.

Health Landscape

This study clarifies the current gap between clinical screening goals and real-world adherence for colorectal health in the United States. It illustrates how lack of insurance and primary care access serve as structural barriers to implementing the standards set by the U.S. Preventive Services Task Force.

If you are between 45 and 75, it is important to confirm you are current on your colorectal cancer screening schedule. If you do not have a regular physician, this is a topic worth discussing with a primary care provider to understand your specific risk and recommended screening timeline.

The takeaway

Regular screenings are a cornerstone of colorectal cancer prevention for adults starting at age 45. Speak with your healthcare provider to confirm your screening status and identify any local options for scheduling a test if you are currently overdue.
