Preventive gynecologic care is a cornerstone of women's health, yet millions of women living with disability may be systematically excluded from it — not by choice, but by structural and clinical failure. A large-scale insurance database study now puts hard numbers to a long-suspected disparity, revealing that cerebral palsy functions as an independent predictor of reduced preventive screening across multiple modalities.
Drawing on the PearlDiver national insurance database covering 2010 through early 2022, researchers identified 138,277 adult women with cerebral palsy and matched them 1:4 by age to 553,102 women without the condition. Rates of routine gynecologic examinations, Pap smear testing, and mammography were tracked across five-year age intervals from 20 to 69 years. After controlling for age, comorbidity burden via the Elixhauser Comorbidity Index, U.S. region, and insurance type, cerebral palsy remained a statistically significant independent predictor of lower utilization across all three screening categories — meaning the gap cannot be explained by demographic or insurance-related confounders alone.
This finding sits within a growing body of evidence documenting healthcare disparities among people with physical disabilities, a population that clinicians often deprioritize for preventive care under the flawed assumption that competing medical concerns take precedence. Women with cerebral palsy face real practical barriers — including inaccessible examination equipment, difficulty tolerating pelvic exams, and provider uncertainty about adapting standard protocols — but the scale of this study (nearly 700,000 matched individuals) makes a strong epidemiological case that the gaps are system-wide, not incidental. The observational design limits causal inference, and insurance-based datasets miss the uninsured. Still, the magnitude and consistency of the disparity across age groups and screening types signal a genuine public health concern. Gynecologic cancers are highly treatable when caught early; closing this screening gap could meaningfully reduce preventable morbidity in a population already navigating substantial health challenges.
