Using Lunar DPX-L DXA, the BMD of 518 subjects were measured from June 1995 to July 1996. The 93 excluded cases include minority nationalities, southern chinese or underlying patients. Modifying BMD by body weight, the measurement results of 45 healthy subjects showed: in male the age of formatting peak bone is 20 ∼ 24 at lumbar, proximal femur and total body, however in female is 25 ∼ 29 at the same sites. Before the age of 40, the BMD of all sites in both sexes are basic stable. Further working plan were reported in this paper. (author)
