【Abstract】 The bone mineral density (BMD) was investigated by dual energy X-ray absorptiometry (DEXA) for 618 cases normal peoples in this paper.Of those,men were 283,women were 335,the average ages ranged from 20 to 86 years old.The results showed that the BMD peak values of lumbar spine could be seen in 30～39 years old group for females and in 20～29 group for males.However the peak bone mass of femoral neck,ward’s and trochanters were found in 20～29 years old group of both sexes.The bone loss was increased for females after 50 years old,but that for males was slower than for females over 50 years.The rate of accumulative loss of BMD seemed higher for females than males.更多还原
