Résumé
ultrasound (QUS) parameters and the intermethods agreement in active males. Methods: In this cross-sectional study, bone health
(by DXA and calcaneal QUS), physical activity (by accelerometers), and anthropometrics measurements were assessed in 117
active adolescents (12–14 y old). Bivariate correlation coefficients were calculated to assess the relationships between DXA
standard regions of interest and QUS parameters. Intraclass correlation coefficients and Bland–Altman plots were used to assess
the level of agreement between bone mineral content regions derived from DXA and stiffness index. The measurements were
z score transformed for comparison. Results: Most QUS parameters were positive and significantly correlated with DXAoutcomes
(stiffness index: r = .43–.52; broadband ultrasound attenuation: r = .50–.58; speed of sound: r = .25–.27) with the hip showing the
highest correlations. Moreover, the present study found fair to good intraclass correlation coefficients of agreement (.60–.68)
between DXA and QUS to assess bone health. The Bland–Altman analysis showed a limited percentage of outliers (3.2%–8.6%).
Conclusion: QUS device could represent an acceptable alternative method to assess bone health in active adolescent males.
