Introduction. Bone mineral density (BMD) is used to diagnose osteoporosis. According to World Health Organization (WHO) osteoporosis was defined as a BMD value more than 2.5 standard deviations below the mean for normal young white women. X-ray absorptiometry (DXA) of proximal femur and lumbar spine is currently the gold standard used to confirm this diagnosis. Recent published studies introduced an innovative echographic approach, defined as REMS technology. The aim of this study is to compare REMS-based BMD values of lumbar spine and femoral neck between premenopausal and postmenopausal women. Methods. In this study, a total of 165 women underwent echographic scan using REMS technology. Acquisitions of lumbar spine and femoral neck were done for each patient in two Bulgarian centers. The following characteristics of the women were recorded: age, weight, height, BMI and REMS-based BMD of lumbar spine L1-L4, total lumbar spine, femoral neck, trochanter and total hip. Results. The mean REMS-based BMD measurements of postmenopausal group of L1-L4 and total lumbar spine were significantly lower than those of the premenopausal group (p=0.000). Femoral neck REMSbased BMD (p=0.011), trochanteric REMS-based BMD (p=0.007) and total hip REMS-based BMD (p=0.009) also differed significantly between the premenopausal and postmenopausal group. Conclusion. Postmenopausal women showed significantly lower lumbar spine REMS-based BMD of L1-L4 and total lumbar spine REMS-based BMD compared to premenopausal women. Femoral neck REMS-based BMD of postmenopausal women was also significantly lower than those of premenopausal women. [ABSTRACT FROM AUTHOR]
