Abstract

The purpose of the study is to estimate prevalence of fragility fractures (FF), risk factors, and treatment rates in senior women and to assess impact of FF on physical function and quality of life. Women aged 65years and older from the EpiReumaPt study (2011-2013) were evaluated. Rheumatologists collected data regarding FF, clinical risk factors for fractures, and osteoporosis (OP) treatment. Health-related quality of life (EQ5D) and physical function (HAQ) were analyzed. Peripheral dual-energy X-ray absorptiometry was performed. FF was defined as any self-reported low-impact fracture that occurred after 40years of age. Prevalence estimates of FF were calculated. Among 3877 subjects evaluated in EpiReumaPt, 884 were senior women. The estimated prevalence of FF was 20.7%. Lower leg was the most frequent fracture site reported (37.8%) followed by wrist (18.6%). Only 7.1% of the senior women reporting a prevalent FF were under treatment for OP, and 13.9% never had treatment. OP treatment was not prescribed in 47.7% of FF women, and 23.4% refused treatment. Age (OR = 2.46, 95% CI 1.11-5.47), obesity (OR = 2.05, 95% CI 1.14-3.70), and low wrist BMD (OR = 2.29; 95% CI 1.20, 4.35; p = 0.012) were positively associated with prevalent FF. A significantly higher proportion of women in the lowest quintile of wrist bone mineral density reported FF (OR = 2.29, 95% CI 1.20-4.35). FF were associated with greater physical disability (β = 0.33, 95% CI 0.13-0.51) independent of other comorbidities. FF was frequently reported among senior women as an important cause of physical disability. However, the prevalence of OP treatment was low, which constitutes a public health problem in this vulnerable group.
