Racial Disparities in the Prevalence of Arthritis among Native Hawaiians and Pacific Islanders, Whites, and Asians

摘要

The health disparities of Native Hawaiians and Pacific Islanders (NHPI) are well established for diabetes and cardiovascular disease, but less is known about disparities in arthritis. This study examined possible disparities in the prevalence of arthritis by age, sex, and severity comparing NHPI, Whites, and Asians. The study population included adult Hawai‘i participants in the 2013 Behavioral Risk Factor Surveillance Survey. NHPI males had a significantly higher prevalence of arthritis, which peaked twenty years earlier, than White and Asian males (P<.001). The prevalence of arthritis peaked at 65–79 years in males and females in all racial groups, except in NHPI males where it peaked at 45–54 years. The mean ages (years) for males with arthritis were 46.2 for NHPI, 59.1 for Whites, and 60.5 for Asians; the respective ages for females were 54.2, 60.5, and 58.8. NHPI males body mass index averaged 2.4 kg/m2 greater than White males (P<.001), and obese NHPI males had twice the age-adjusted odds of arthritis than obese White males. Although NHPI females had a greater body mass index than White females (P=.05), the prevalence of arthritis was only slightly and not significantly higher. NHPI males and females reported high pain scores more frequently than Whites did, but the differences did not reach statistical significance. Diabetes was a comorbidity more than twice as often in NHPI and Asians of both sexes than among Whites. This study demonstrated racial disparities in the prevalence of arthritis among NHPI, Whites, and Asians.
