This study was designed to establish @entity79 ( @entity79 ) Reference Databases for multiple skeletal sites appropriate for the diagnosis and evaluation of @entity170 ( @entity170 ) in Chinese @entity1 . We recruited 2702 healthy Chinese @entity1 , 5-96 years of age, for @entity79 assessment. @entity79 values at multiple skeletal sites including anteroposterior (AP) and lateral (Lat) lumbar spine, hip, and forearm were measured by dual-energy X-ray absorptiometry (DXA) using a QDR 4500A device; results were analyzed according to age group using eight regression models. @entity79 Reference Databases (CWD) were established according to the best regression equation and compared with Hologic reference databases for "Oriental @entity1 " (OWD). Results indicated that the cubic regression model was superior to the quadratic, linear, logarithmic, and exponential regression models, etc. for our purpose, with a determinate coefficient ( R(2)) of 0.363-0.650 ( P = 0.000). We included 1636 female @entity1 , aged 35-86 years, in our tests. In comparison with Hologic Reference Databases, the mean detection rate of @entity170 in the newly established @entity79 Reference Databases for Chinese @entity1 (CWD) was 16.0% +/- 2.68% lower (range, 13.7%-20.5%) at the AP spine, 16.8% +/- 11.0% lower (range, 3.5%-32.8%) at the Lat spine (except for L4), 18.7% +/- 4.6% lower (range, 12.6%-24.2%) at the hip, and 14.3% +/- 6.9% higher (range, 4.7%-24.3%) at the forearm. The difference in detection rates for @entity170 was significant between the two reference databases ( P = 0.000), which was consistent with the differences in peak @entity79 values and the biological variability between them. Based upon our data, we confirmed that the Hologic @entity79 Reference Databases for Oriental @entity1 (OWD) were not suitable for the diagnosis of @entity170 in Chinese @entity1 ; the @entity79 Reference Databases for Chinese @entity1 (CWD) established in this study would provide reliable diagnostic standards for detection of @entity170 in the @entity1 of South China.
