The Association Between Experienced Discrimination and Pain in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study

Background: The relationship between experienced discrimination and its effects on pain interference and management among racial disparities is not well explored. This research investigated these associations among Black and White U.S. adults.

Methods: The analysis involved 9369 Black and White adults in the REasons for Geographic and Racial Differences in Stroke (REGARDS), assessing experiences of discrimination, pain interference (SF-12), and pain treatment, incorporating factors like demographics, comorbidities, and stress.

Results: Black participants experiencing moderate discrimination were found to have a 41% increased likelihood of pain interference (aOR 1.41, 95% CI 1.02-1.95), similaritythose facing high levels of discrimination also showed a 41% increase (aOR 1.41, 95% CI 1.06-1.86) compared to those without such experiences. White individuals reporting moderate discrimination also faced a heightened risk, with a 21% greater chance of pain interference (aOR 1.21, 95% CI 1.01-1.45). Notably, the presence of moderate discrimination among Black participants correlated with a 12% reduced probability of receiving pain treatment (aOR 0.88, 95% CI 0.56-1.37). Furthermore, Black, and White individuals who reported discrimination when seeking employment had a 33% (aOR 0.67, 95% CI 0.45-0.98) and 32% (aOR 0.68, 95% CI 0.48-0.96) lower likelihood, respectively, of receiving treated pain.

Conclusion: The study elucidates how discrimination exacerbates pain interference and restricts access to treatment, affecting Black and White individuals differently. These findings underscore an urgent need for strategies to counteract discrimination's negative effects on healthcare outcomes. Addressing these disparities is crucial for advancing health equity and improving the overall quality of care.
