An inappropriate reference range for peak bone mineral density (BMD) may result in identification of an incorrect proportion of subjects with osteopenia and osteoporosis at dual-energy X-ray absorptiometry (DXA). In this study, we assessed the prevalence of low BMD in Turkish young adults with respect to local population reference range T-scores and the US reference range T-scores. The BMD values of lumbar spine (L1-L4) and proximal femur (femoral neck, intertrochanter, trochanter, Ward's triangle and total) were measured by DXA in 323 healthy young adults (171 women, 152 men) aged 19-25 years.
