Epidemiological transition to mortality and re-fracture following an initial fracture

Abstract

This study sought to redefine the concept of fracture risk that includes refracture and mortality. We analysed data obtained from 2046 women and 1205 men aged 60+ years, whose health status, including bone mineral density (BMD), has been monitored. During the 20-year follow-up period, among 632 women and 184 men with a first incident fracture, the risk of sustaining a second fracture was higher in women (36%, n=229) than in men (22%, n=41), but mortality risk was higher in men (41%, n=75) than in women (25%, n=156). Key predictors of subsequent fracture risk included advancing age (hazard ratio [HR] 1.17; 95%CI, 1.08-1.26) and low BMD (HR 1.41; 1.23-1.61). Predictors of mortality were male gender (HR 2.4; 1.79-3.21), advancing age (1.67; 1.53-1.83), and lower femoral neck BMD (1.16; 1.01-1.33). These results were incorporated into a prediction model to aid patient-doctor discussion about fracture vulnerability and treatment decisions.
