Objective:
The quantitative ultrasound (QUS) method has been recognized as an optimal screening tool for assessing bone mass status. The aim of this study was to provide standardized values for bone health status measured by the QUS technique based on age, sex, and body mass index (BMI).
Methods:
The study population consisted of 1322 healthy individuals (822 females and 500 males) aged 14-25 years. Bone mass in both calcaneus was estimated with QUS to obtain Broadband ultrasound attenuation (BUA) (dB/MHz).
Results:
The linear models revealed statistically significant differences between bone mass status of the calcaneus and age, sex, and BMI (P < .001). Bone mass increased at a rate of approximately 0.015 units per year after the age of 14 and these values increased in approximately 0.1 units in males in comparison to females. There was an increase of approximately 0.17 units for each increase in categories of BMI.
Conclusion:
It is crucial to provide standardized values for the QUS parameter in young males and females to allow reliable comparisons and evaluate trends in preventive programs that may enable the identification of individuals at risk for osteoporosis.
