Most DXA (dual-energy x-ray absorbtiometry) manufacturers are not able to provide specific reference values for their equipment yet. The mean bone mineral density can vary among different populations.The aim of this study was to identify local reference values from a group of Turkish women living in Istanbul, in order to compare with the results obtained from other countries. We measured BMD at the lumbar spine, proximal femur, forearm, and total body in 205 healthy women between ages 20–79. They are all residents in Istanbul. Bone mineral density measurement was performed by DXA equipment. All measurements were made by an experienced technician in our hospital, using the same DXA equipment. Subjects enrolled in the study also filled in a questionnaire before the test.The mean age at menopause was 46.29 (± 14.28) years. Peak bone mineral density values were obtained in the 20–39 year age group when measured at the ultradistal radius, however, peak values were in the 30–39 age group when measurements were made at other sites. The number of women who had bone loss was higher with the forearm measurements compared to measurements made from the spine and femur. Bone mineral density values measured from the spine, hip, and forearm in our study group were lower than the values from American and European women, on the other hand, total body bone mineral density values from our group were higher than the values reported from western countries. Bone mass from different populations varies due to genetic and geographical factors. We, therefore, suggest that each country should use their localized reference values for bone mineral density measurement.
