Objective: To evaluate the bone mineral density (BMD) of the axial and appendicular skeleton in a group of collegiate dance students undergoing intensive training between a 24 months interval and to correlate these changes to the presence or absence of apparent athlete triad syndrome (ATS).Methods: Forty full time collegiate dance students were recruited from a tertiary Performing Arts Institute. All subjects had basic anthropometric measurements, a full...

Objective: To evaluate the BMD changes around 2 years after delivery using standard dual energy X-ray absorptiometry (DXA) of the lumbar spine and hip, peripheral quantitative computerized tomography (pQCT) of the distal tibia and radius, and quantitative ultrasound (QUS) of the oscalcis.Methods: Consecutive patients with uncomplicated singleton pregnancies were recruited from a general obstetric clinic. Standard BMD measurements of the lumbar spine and ...

Objective: To compare whether interval BMD changes in adolescent females that can be detected using conventional dual energy X-ray absorptiometry (DXA) can also be detected using quantitative peripheral quantitative computerized tomography scans (pQCT) and quantitative ultrasound (QUS)of the os calcis.Methods: Two groups of adolescent females were recruited for assessment of BMD changes over an interval of 22–24 months. These included full time coll...

Background: Prolonged hypothalamic amenorrhoea with anovulation has been associated with hypo-oestrogenism in adolescents and has been shown to be associated with lower bone mineral density (BMD) values.Objective: To determine whether differences in BMD between oligo/amenorrhoeic adolescents at risk of low BMD and normal eumenorrhoeic controls can be detectable by quantitative ultrasound (QUS) of the os calcis.Methods: Adolescents ...
