osteoporosis is a major public health problem in iran. bone densitometry is used to diagnose osteopenia and osteoporosis and if necessary, prevent bone fractures, especially that of femoral neck. bone density is related to several factors including race, age, sex, environmental factors and nutrition. no comprehensive study has been performed in iran, yet. among the 10 to 75 year-old population ...

background there is evidence in support of low bone density in young patients with disorders of phenylalanine metabolism; however, little is known about muscle and fat mass in these patients, especially in those with mild hyperphenylalaninemia (mhpa). objectives we aimed to evaluate body composition of children and adolescents with early-diagnosed disorders of phenylalanine metabolism. patients...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...

background: tea consumption is common in our country and consumes more than coffee and other drinks. many studies investigated the association between coffee and bone mass density (bmd) but there is few study about association between tea and bmd. according to high prevalence of osteoporosis in country and change in demographic patterns that is associated with increasing middle-aged and older a...

A 14-year-old girl with type-III Ehlers-Danlos syndrome (EDS) underwent a dual energy X-ray absorptiometry (DXA) evaluation of the bone mineral density (BMD) in the scoliotic lumbar spine (L-spine), which measured 0.464 g/ cm (T-score: -5.3, Z-score: -4.23) (Picture 1). The BMD was found to be 0.230 g/cm (T-score: -4.5) in the deformed distal forearm and 0.181 g/cm (T-score: -4.1) in the ultrad...

Osteoporosis is a disease characterized by low bone mass and micro architectural alterations of bone tissue leading to enhanced bone fragility and increased fracture risk. Although research in osteoporosis has focused mainly on the role of bone loss in the elderly population, it is becoming increasingly clear that the amount of bone that is gained during growth is also an important determinant ...
