[Osteoporosis prevalence in Croatian males--the results of calcaneus ultrasound].

The aim of the study was to establish the normative QUS data in a healthy sample of Croatian males and estimate the prevalence of osteoporosis. A total of 1002 male participants, aged 20-99, were recruited in seven study centers (Zagreb, Ivanić-grad, Koprivnica, Sibenik, Pula, Slavonski Brod, Vukovar). In each subject broadband ultrasound attenuation (BUA), speed of sound (SOS) and quantitative ultrasound index (QUI) of the calcaneus were measured using the Sahara ultrasound device.
