ABSTRACT
The correct interpretation of bone mineral density [BMD] measurement by dual energy x ray absorptiometry [DEXA] requires a population specific reference range. We collected data on age 20-35 years to obtain reference values of BMD for Isfahani women in order to make a population specific diagnosis of osteoporosis. In 660 healthy Isfahani women Volunteers [20-35 years] without illness, use of drugs or predisposing conditions to osteoporosis, the BMD [gr/cm 2] of lumbar spine and non-dominant femur was measured by lunar DPX -IQ machine. The mean BMD and its standard deviations at each site were calculated and compared with normative data from Caucasian US/North European women. No significant differences were detected between them. Bone mineral density measurements of these 660 healthy Isfahani women can serve as a reference guide for the diagnosis of osteoporosis in Isfahani women
