title: [Bone mineral density characteristics at the femoral neck and Ward's triangle for Chinese women].
abstract: The incidence of hip fracture is not as high in Chinese women compared to women from Western countries, though they usually have low bone mineral density(BMD) and get osteopenia easily. In this study, reference data(white women) supplied by the manufacturer of Hologic was compared with data obtained from healthy women in Changsha, Hunan, P.R.C. One thousand four hundred and eighty-eight Chinese women aged 15 to 95 years were randomly recruited. Measurements of BMD were taken at the hip by the dual energy x-ray absorptiometry(QDR 4,500A, Hologic Inc., USA). The BMD was somewhat lower than reference curves at all ages and all sites. But at the femoral neck and Ward's triangle, Chinese women reached their peak BMD 5 to 10 years later than the reference group, and had a lower BMD rate of decrease for about 35 years after peak BMD was reached. Whether the differences(i.e., longer time to peak BMD and a lower BMD decrease rate at the neck and Ward's triangle after the peak BMD reached) will result in a protection from hip fractures for Chinese women needs to be studied in the future.
