To the Editor: The article by Aldhafiri et al1 raises several clinically relevant issues. As addressed in the principle objective given in the study, measurement of bone mineral density in children by dualenergy x-ray absorptiometry (DXA) requires adjustment for height and weight, therefore providing validation of our observations reported in 2009.2 Secondly, it is important to establish local ...

Osteopenia, term of child pathologies, is a decrease in bone mass relative to chronological age, being an intermediate state between normal bone mass and osteoporosis. It has multiples etiological factors, comprising a heterogen group of diseases of the connective tissue with genetic determinism and osteopenia gained in various pathological conditions affecting bone homeostasis. Early diagnosis...

The insulin-sensitizing effect of adiponectin (1–4) is mediated via adiponectin receptors (AdipoR1 and AdipoR2) (5). AdipoR1 is abundantly expressed in skeletal muscle, whereas AdipoR2 is also expressed in the liver, with lower levels of expression in skeletal muscle (5). Both receptors are expressed in adipose tissue (6) and pancreatic -cells (7). It has been shown recently that expression of ...

fracture. Several chronic medical conditions, medications, and life style factors affect bone mineral accrual. This study aims to evaluate the bone mineral densities and hip axis lengths in the local population. Materials and Methods: 336 normal Bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). Results:...

Bone densitometry (dual energy x-ray absorptiometry-DXA) is a vital medical tool needed for the diagnosis of osteoporosis in non-fractured patients; predicting future fracture risk; and monitoring bone mineral density (BMD) in untreated or treated patients. The history of the pivotal international society involved in the science and clinical interpretation of DXA, the International Society for ...

OBJECTIVE To examine the ability to use Quantitative Ultrasonography (QUS) densitometer for screening of osteoporosis and osteopenia by comparing QUS values obtained at the calcaneus region to bone mineral density (BMD) values measured at the spine and the neck of the femur using Dual Energy X-ray Absorbemetry (DXA). METHODS QUS (in the calcaneus region) and DXA (the spine and the neck of fem...

Dual-energy X-ray absorptiometry (DXA) in single energy mode has been shown to permit the visualisation of bone and soft tissue, such as patellar tendon through two-dimensional sagittal imaging. However, there is no validated DXA-based measurement Achilles moment arm (dAT). The aims this study were: 1) compare vivo DXA derived measurements dAT at rest against two previously methods: excursion (...

OBJECTIVE We compared body composition estimates using an eight-electrode, segmental, multiple-frequency bioelectrical impedance analysis (segmental MF-BIA) and dual x-ray absorptiometry (DXA) in a group of healthy adults with a range of body mass indexes (BMIs). METHODS Percentage of body fat (%BF), fat-free mass, and fat mass assessed by DXA and segmental MF-BIA in 132 healthy adults were c...

OBJECTIVE To determine whether categories of obesity based on BMI and an anthropometry-based estimate of fat mass percentage (FM% equation) have similar discriminative ability for markers of cardiometabolic risk as measurements of FM% by dual-energy X-ray absorptiometry (DXA) or bioimpedance analysis (BIA). DESIGN AND METHODS A study of 40-79-year-old male (n = 205) and female (n = 388) Finns...

Excess visceral adipose tissue (VAT) is associated with a cluster of metabolic abnormalities. A new dual-energy X-ray absorptiometry (DXA)-based VAT measurement approach, CoreScan™, computes VAT mass and volume within the android region of a total body DXA scan. However, there have been no reference values developed for this method. The objective of this study was to determine the normal refere...
