Abstract
The study’s aims were to first determine if racial/ethnic disparities in ADL limitations for low-income Medicare beneficiaries. The logistic regression results suggested there is a variance in ADL limitation among Medicare Beneficiaries across race. Then, it tested if low-income elderly Medicare enrollees aged 65 years and older were at a higher risk of experiencing transportation barriers to care. On account of covariates, persons with ADL limitations (OR: 2.47 p<0.001) had higher odds of having transportation barriers compared to those without ADL limitations. Non-Hispanic African Americans had a higher chance of experiencing transportation delays than non-Hispanic Whites (OR 1.76 p<0.001). Finally, the effect size for transportation access barriers did not have a dose-relationship with increasing ADL limitation severity. Though the point estimates suggested that barriers were greatest for those with moderate severity (3-4 ADLs), it failed to find evidence of a statistically significant dose-response relationship between ADL severity and transportation.
