The aim of this study was to determine the range of bone mineral density (BMD) in a normal Turkish female population and to compare them to USA and Northern European data. BMD measurements were performed at four sites (antero-posterior spine, femur, ultradistal radius, total body) in 339 women aged 20-79 years using a Lunar DPX densitometer at 19 different centers from different areas of the country. There was a linear correlation between BMD and both body weight and body mass index especially in postmenopausal stage. Spinal peak bone density (PBD) was reached in the 30-39 year age group whereas femoral PBD was reached in the 20-29 age group. The major fall in the BMD was observed after 50 years related to the menopause at all measurement sites. BMD showed a parabolic decline with aging. There was a cubic decreasing trend in BMD values at all sites related to the time since menopause. In comparison with USA and Northern European data, BMD values in Turkish women were lower at lumbar spine, whereas their femoral BMDs were similar to USA values but lower than Europeans in the 5th and 7th decades.
