Recent trends in hip fracture rates by race/ethnicity among older US adults. uri icon


  • Hip fracture incidence has declined among whites in the United States since 1995, but data on recent trends in racial and ethnic minorities are limited. The goal of this analysis was to investigate hip fracture incidence trends in racial/ethnic subgroups of older Medicare beneficiaries. We conducted a cohort study to determine annual hip fracture incidence rates from 2000 through 2009 using the Medicare national random 5% sample. Beneficiaries were eligible if they were 65 years of age and had 90 days of consecutive full fee-for-service Medicare coverage with no hip fracture claims. Race/ethnicity was self-reported. The incidence of hip fracture was identified using hospital diagnosis codes or outpatient diagnosis codes paired with fracture repair procedure codes. We computed age-standardized race/ethnicity-specific incidence rates and assessed trends in the rates over time using linear regression. On average, 821,475 women and 632,162 men were included in the analysis each year. Beneficiaries were predominantly white (88%), with African, Hispanic, and Asian Americans making up 8%, 1.5%, and 1.5% of the population, respectively. We identified 102,849, 4,119, 813, and 1,294 hip fractures in white, black, Asian, and Hispanic beneficiaries over the 10 years. A significant decreasing trend (p<0.05) in hip fracture incidence from 2000-2001 to 2008-2009 was present in white women and men. Black and Asian beneficiaries experienced nonsignificant declines. Irrespective of gender, the largest rate of decline was seen in beneficiaries 75 years of age. The overall and age-specific rates of Hispanic women or men changed minimally over time. Hip fracture incidence rates continued to decline in recent years among white Medicare beneficiaries. Further research is needed to understand mechanisms responsible for declining rates in some and not others, as hip fractures continue to be a major problem among the elderly.
