Abstract
Standard projectional bone density of the femoral neck (BMD), defined as bone mineral content divided by the projected area of the neck, pre dicts hip fractures but may not accurately estimate the true volumetri c bone density of the femoral neck. To determine whether an estimate o f the volumetric bone density of the neck, ''bone mineral apparent den sity'' (BMAD), would be a better predictor of hip fracture, we analyze d dual x-ray absorptiometry scans obtained prospectively from 7963 old er white women, of whom 83 suffered a hip fracture during follow-up. B oth BMD and BMAD were stronger predictors than bone mineral content (B MC) of the femoral neck. However, BMD and BMAD had very similar predic tive values for hip fracture: each standard deviation decrease in eith er BMD or BMAD of the femoral neck increased the age-adjusted risk of hip fracture 2.6- to 2.7-fold. We conclude that BMD and BMAD of the fe moral neck have a similarly strong predictive value for hip fracture.
