Determination Of Bone Mineral Density By Absorptiometry To Han And Uygur Nationality In Normal People In Urumqi

Objective: To determine bone mineral density (BMD) of Han and Uygur nationality in health in Urumqi and further to investigate the change regularities of BMD with age. Methods: BMD values of lumber spine and proximal femur in healthy subjects were determined by duel energy X-ray BMD detector (Model lexxos made by DMS co.Ltd, France) in Urumqi residents whose ages over 20-75. The mean BMD value, standard deviation (SD) and according to different sex and age which per 5 years be in one group. Result: The peak bone mass for each skeleton site appeared in different ages both Han and Uygur nationality. The females BMD showed a sharp decline after 50 years while no such a tendency occurred in males post the peak. Conclusions: This study may provide useful evidence and data for osteoporosis study in the Han and Uygur ethnic group of Urmuqi area.
