The aim of this study was to examine the effect of different reference ranges in bone mineral density on the diagnosis of osteoporosis.

This cross-sectional study involved 357 men and 870 women aged between 18 and 89 years, who were randomly sampled from various districts within Ho Chi Minh City, Vietnam. BMD at the femoral neck, lumbar spine and whole body was measured by DXA (Hologic QDR4500). Polynomial regression models and bootstraps method were used to determine peak BMD and standard deviation (SD). Based on the two parameters, we computed T-scores (denoted by T _VN) for each individual in the study. A similar diagnosis was also done based on T-scores provided by the densitometer (T _DXA), which is based on the US White population (NHANES III). We then compared the concordance between T _VN …
