Abstract
CONTEXT AND OBJECTIVE: It is not known which factors are associated with fracture in nonosteoporotic elderly. The aim of this study was to assess the association between fall-related risk factors and fracture risk in men and women without osteoporosis. DESIGN: This study was part of the ongoing Dubbo Osteoporosis Epidemiology Study, which was designed as a prospective population-based cohort investigation. PARTICIPANTS: At baseline, 924 women and 723 men aged 60+ yr did not have osteoporosis [bone mineral density (BMD) T-scores > -2.5]. The individuals have been followed for up to 15 yr. MAIN OUTCOME MEASURES: Atraumatic fractures were prospectively identified through radiologists' reports. RISK FACTORS: At baseline, femoral neck BMD (FNBMD) was measured by dual energy x-ray absorptiometry (DXA); history of fall, postural stability, and quadriceps strength was obtained. RESULTS: During the follow-up period, among the nonosteoporotic group, 221 women and 105 men had sustained a fracture, accounting for 55 and 74% of total fractures in the entire Dubbo Osteoporosis Epidemiology Study sample, respectively. The following factors were independent risk factors for any fracture: in women, age per sd (hazard ratio, 1.2; 95% CI, 1.0-1.3), postural sway per sd (1.1, 1.0-1.2), FNBMD per sd (1.6, 1.3-1.9), fall in the previous 12 months (2.1, 1.6-2.7), and prior fracture (1.8, 1.2-2.7); in men, age (1.4, 1.1-1.6), postural sway (1.2, 1.0-1.3), FNBMD (1.2, 1.0-1.5), and fall in the previous 12 months (1.9, 1.2-3.0). Exposure to at least one of the risk factors could account for 49% (women) and 39% (men) of any fractures in this population. CONCLUSION: In nonosteoporotic elderly, the combination of low BMD, advancing age, fall during the last 12 months, and prior fracture could identify a subgroup of individuals with high risk of fracture.
