Assessing Intersectional Disparities in Cervical Cancer Screening by Disability Status, Race, and Ethnicity

Separate bodies of research have studied disparities by disability status and by race or ethnicity in receipt of cervical cancer screening. Much less is known about how these disparities intersect. The purpose of this study was to evaluate disparities in compliance with the U.S. Preventive Services Task Force guidelines for Pap testing in age-eligible women at the intersection of disability and race or ethnicity.

We conducted cross-sectional analyses of the Medical Expenditure Panel Survey Household Component deidentified public data files pooled for years 2007-2016, using a modified Poisson regression analysis to compute prevalence ratios for being up to date with Pap testing by disability status and race or ethnicity. We also calculated predicted marginal proportions adjusting for demographic and socioeconomic covariates.

The analytic sample included 68,507 women with nonmissing covariates; 15.6% had a disability. Overall, the proportion current with Pap testing was significantly lower among women with disabilities than among those without disabilities (82.1% vs 88.6%, p<0.0001). Furthermore, within each racial and ethnic group, women with disabilities were less likely than those without disabilities to be current with Pap testing. In adjusted analyses, prevalence ratios for White women with disabilities (adjusted prevalence ratio=0.94; 95% CI=0.92, 0.96) and other race women with and without disabilities (adjusted prevalence ratio=0.91; 95% CI=0.86, 0.95 and adjusted prevalence ratio=0.91; 95% CI=0.89, 0.95, respectively) were significantly below those for the reference group of White women without disabilities. Hispanic women with disabilities did not differ significantly from White women without disabilities, and Black women with disabilities had significantly higher adjusted prevalence ratios than White women without disabilities (adjusted prevalence ratio=1.07; 95% CI=1.05, 1.09). When taking covariates into account, the proportion of Black women with disabilities current with screening was only slightly lower than the estimated proportion for Black women without disabilities (92% vs 93%). The gap in screening between White women with and without disabilities narrowed somewhat (from 9 percentage points to 4 percentage points) but remained significant.

Our results extend previous research focused separately on disability or race and ethnicity. Women with disabilities in all racial and ethnic groups fell short of Healthy People 2020 goals for cervical cancer screening.
