Racial and Socioeconomic Disparities in Disabling Chronic Pain: Findings From the Health and Retirement Study.

The U.S. National Pain Strategy calls for increased population research on "high-impact chronic pain" (ie, longstanding pain that substantially limits participation in daily activities). Using data from the nationally-representative Health and Retirement Study (HRS), we investigated the prevalence of high-impact chronic pain in U.S. adults older than age 50 overall and within population subgroups. We also explored sociodemographic variation in pain-related disability within specific activity domains. Data are from a subsample of HRS respondents (n = 1,925) who were randomly selected for a supplementary pain module in 2010. Our outcome was operationalized as pain duration of ≥7 months and a disability rating of ≥7 (0-10 scale) in at least 1 domain: family/home, leisure, social activities, work, or basic activities. Overall, 8.2% (95% confidence interval = 6.7-10.1%) of adults older than age 50 met criteria for high-impact chronic pain. This proportion rose to 17.1% (95% confidence interval = 12.3-23.4%) among individuals in the lowest wealth quartile. Prevalence differences according to education, race/ethnicity, and age were not significant. Arthritis and depression were significantly associated with high-impact pain in multivariable analysis. Among adults with any chronic pain, African American and individuals in the lowest wealth quartile reported more pain-related disability across activity domains.
