Bone mineral density (BMD), a measure of bone strength, is a strong predictor of hip fracture risk [ 2], and is used as a surrogate measure of the severity of osteoporosis [ 3], the mechanism of BMD-hip frelationshiptisnotip is not well understood.
After ultrasound tests, the researchers found that the children in the pain group had decreased "bone speed of sound" — a measure of bone strength and breakability — suggesting that they suffered instead from "a local overuse syndrome".
36 It is possible to also derive a measure of bone strength in the form of SSI.
Radiograph-assessed cortical bone width as a measure of bone strength and bone loss was proposed in 1960 using radiographs of the hand bones [ 12, 13].
Cortical area, or, since cortical bone mineral density shows very little inter-individual variation, also bone mineral content, can serve as a surrogate measure of bone strength in compression [18,33].
This proposal of a lower requirement for Si in humans appears not to fit with our previous observational data reporting higher intakes of dietary Si to be associated with higher bone mineral density (BMD, a measure of bone strength) and thus better bone health [18,19].
Furthermore, only BMC and BMD measurements were available in this study, and consequently no other measures of bone strength could be explored, neither could counts of bone formation markers.
Outcome measures included bone strength, bone histomorphometry and architecture, serum IGF-1 and osteocalcin.
Surrogate measures of bone strength increased, particularly in the tibia diaphysis, as the discipline-specific speed increased.
Both birthweight and conditional weight at 1 year were related to measures of bone strength (fracture load X, fracture load Y, polar strength strain index) at both the radius and tibia.
