| Objective: Through measuring the bone mineral density of 1485 healthy people of Uygur dwellings in Urumqi Xinjiang ,certaining the reference valus of bone mineral density in Urumqi.To analyze the regularities of changes in bone mineral density(BMD) . Methods:The BMD of anteroposterior position of lumbar and proximal femur in left were measured by DMS Lexxos dual emengy x-ray absorptiometer (DEXA)for health people of Uygur dwellings in Urmqi (aged more than 20 years).we can make 5 years for one age group,obtain the typical value of BMD,root-mean-square error,the percent of accumulate loss.Result:The BMD peak values of anteroposterior position of lumbar were seen in 35-year-old group for males and females.However,the peak bone mass of proximal femur was found in 20-year-old groups of both sexes.BMD diminished with increasing age.the bone loss was sharply decreased for females after 50 years of age.but that of males was progressive and slow.Conclusions: The prevalence of osteoporosis in female was higher than that of male in Urumqi.The prevention and treatment of osteoporosis are very important to the female but should not be ignored in male .Setting up the peak value of bone and the reference values of bone mineral density in Urumqi.It is important for us to diagnose the primary osteoporosis in early. |
