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.
