osteoporosis is a major health problem because of the large health care costs associated with its clinical consequences. it is therefore of great importance to identify modifiable risk factors. we investigated association between fruit and vegetables intake and bone mineral density in rural population of tehran surroundings. subjects were a subgroup of a large study on prevalence and causes of ...

background patients with thalassemia major and intermedia are susceptible to osteopenia and osteoporosis. the mechanism of osteoporosis in these patients is multifactorial. transfusion related iron overload in endocrine organs leads to impaired growth hormone secretion, diabetes mellitus, hypothyroidism, hypoparathyroidism, lack of sex steroids and vitamin d deficiency that contribute to impair...

BACKGROUND Persons with unilateral, lower-extremity amputation sometimes develop osteoarthritis in the intact limb. The purpose of this study was to investigate gait mechanics and bone mineral density in unilateral, trans-tibial amputees to test the hypotheses that the intact limb knee and hip will have larger frontal plane net joint moments and bone mineral density than the prosthetic side and...

Bone tissue is constantly renewed during childhood and adolescence to assure skeleton growth both in size and mineral density: up to 90 percent of peak bone mass is acquired by age 18 in girls and age 20 in boys, which makes youth the best time to "invest" in bone health. The reduction in bone mineral density leading to compromised strength and microarchitecture of bone tissue can favour the oc...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...

background: osteoporosis is a major public health concern around the world. it has been shown that bone mineral den­sity is correlated to anthropometric measures like height and weight, but this association may vary depending on ethnic and environmental factors. the aim of this study was to identify probable relations between anthropometric measures and bone mineral density. methods: in this po...

Introduction: Various therapeutic options such as Calcitonin are suggested for patients with low bone density. However, the efficacy remains uncertain in all patients. C-telopeptide of type I collagen (CTx) is the authentic bone marker which is recently used to assess the bone turnover. This study aimed at revealing the therapeutic effects of Calcitonin on osteopenic women via ...

osteoporosis is a silent epidemy of today's world, and is also a prevalent problem of health in iran. the role of nutrients such as ascorbic acid, a key antioxidant vitamin, in this disease has recently attracted researchers' attention. in this study, we studied the relation between plasma ascorbic acid concentration and bone mineral density (bmd) in women referring to jami clinic, te...

The aim of this study was to study the variation of isokinetic strength and bone mineral density on the lower limb in youth soccer players according to age level. Sixty-one youth male soccer players from three age groups (Under19, Under-17, and Under-15) take part on the study. Hamstrings and quadriceps concentric strength was evaluated by isokinetic dynamometry, and body composition was assess...

PURPOSE The aim of this study was to compare the relation between differently measured sports activities (metabolic equivalent [MET] and peak strain score) and distal radius bone mineral density in college-aged women. METHODS Lifetime sports activity was scored in two different ways: 1) a sports activity score by multiplying the intensity (METs) and duration and 2) a sports activity score by ...
