Abstract

Objective To investigate the bone mineral density(BMD) in part of the population in Xi'an district and provide the basis for prevention,diagnosis and treatment of osteoporosis.Methods The BMDs of 1478 inhabitants of different age group in Xi'an district were measured using dual energy X-ray absorptiometry(DEXA).Results The peak BMDs(PBM) lie in the age group of 20-24 for women,and in the age group of 30-34 for men.but two small BMD peaks occurred in the age group of 30~34、50 in females and of 40、60~64 in men.The bone loss rate and prevalence of osteoporosis increased after 50 years old in women and 55 in men.Conclusions The prevalence of osteoporosis increases with age,especially after 50 years old in women and 55 years old in men.
