BACKGROUND/OBJECTIVES: @entity23398 ( @entity23398 ) is used to measure bone quality and is known to be safe, radiation free and relatively inexpensive compared with dual-energy X-ray absorptiometry (DXA) that is considered the gold standard for bone status assessments. However, there is no consensus regarding the validity of @entity23398 for measuring bone status. The aim of this study was to compare @entity23398 and DXA in assessing bone status in Thai @entity1 . SUBJECTS/METHODS: A total of 181 Thai @entity1 (90 @entity1 and 91 @entity1 ) aged 6 to 12 years were recruited. Bone status was measured by two different techniques in terms of the speed of sound (SOS) using @entity23398 and bone mineral density (BMD) using DXA. @entity460 intake was assessed by 24   h diet recall. Pearson's correlation, k-statistic and Bland and Altman analysis were used to assess the agreement between the methods. RESULTS: There was no correlation between the two different techniques. Mean difference (s.d.) of the Z-scores of BMD and SOS was -0.61 (1.27) that was different from zero (P<0.05). Tertiles of Z-scores of BMD and @entity23398 showed low agreement (k 0.022, P=0.677) and the limits of agreement in Bland and Altman statistics were wide. CONCLUSIONS: Although @entity23398 is easy and convenient to use, the SOS measurements at the radius seem not appropriate for assessing bone quality status.European Journal of Clinical Nutrition advance online publication, 28 October 2015; doi:10.1038/ejcn.2015.180.
