According to evidence based medicine, about 10 years bone mineral density (BMD) results were analyzed retrospectively which came from DEXA, pDEXA, RA, and SPA methods in China mainland. This paper tries to get out Chinese osteoporosis diagnostic criteria more objectively and more exactly. Searching Chinese magazine and paper databases, 52,166 male case-times and 107,929 female case-times BMD lose rate data were quoted and calculated from 49 papers. The average values and standard deviations also were calculated by SPSS 11.0 (SPSS Inc., Chicago, IL) and the BMD lose rate curves were drawn according to 10 to 90 years old phases. It is suggested that the Chinese criteria of osteoporosis diagnosis should use 25% in BMD lost rate or 2 SD. The measure position is suggested in some sequences that femoral neck is better than forearms, lumbar P-A position, phalanges (2nd, 3rd, and 4th) detected by RA and femoral Troch’s region. The femoral WARD’s region and lumbar lateral measurements are not supported. To use evidence based medicine can get more accuracy and more reliable results. It is worthy of developed, deeper research.
