Abstract: Context. In recent years, a large number of techniques have been developed to estimate the bone mineral density for the diagnosis of osteoporosis. However, diagnostic criteria established by WHO are invariably applied for the interpretation of dual radiological densitometry (DEXA), which could not be correct in the case of the interpretation of ultrasound.Method. We studied 2,589 randomly chosen people of both sexes, 1,138 males and 1,451 women from 10 to 99 years, in 11 spanish provinces. We carried out a measurement of the following calcaneous ultrasound parameters with the Sahara(R) and Hologic(R) devices: speed of the sound (SOS), coefficient of attenuation of wide band (BUA), index of consistency (QUI) and estimated bone mineral density (est. BMD). The prevalence of osteopenia and osteoporosis was calculated by applying the WHO criteria (osteopenia Tscore less than or equal to 1 and osteoporosis Tscore less than or equal to 2.5) and the prevalence of osteoporosis by applying a Tscore -1.8 as threshold.Results. According to the WHO criteria, osteoporosis (Tscore less than or equal to 2.5) is seen in 1.5% males and 5.9% females from 51 to 70 years, and in 2.6% males and 22.1% females over 70 years. Using a Tscore -1.8 as threshold, osteoporosis prevalence increases to 8.2% males and 21.9% females from 51 to 70 years, and to 8.4% males and 40.9% females over 70 years.Conclusion. Osteoporosis prevalence in spanish people of both sexes differs notably when applying the cut off point in a Tscore of -2.5, as WHO recommends, or in a Tscore of -1.8 as is suggested by other authors. Consensus is necessary to establish the appropriate cut off point or threshold for the diagnosis of osteoporosis with quantitative ultrasonography of calcaneum.
