To investigate associations of lifestyle factors with bone mineral density among young men in Japan, we measured bone mineral density of the second metacarpal bone in 143 male university students, aged 18-22 years, by the computed X-ray densitometry. The subjects completed a lifestyle questionnaire including a quantitative food frequency questionnaire. Their mean+/-standard deviation of bone mi...

Loeys-Dietz syndrome (LDS) is a rare autosomal-dominant connective tissue disorder caused by heterozygous mutations in the genes encoding transforming growth factor beta receptor 1 or 2 (TGFBR1 or TGFBR2). Although an association between LDS and osteoporosis has been reported, the skeletal phenotype regarding bone mass is not well characterized. Here, we report on two LDS patients with mutation...

BACKGROUND Metabolic bone disease has long been associated with cholestatic disorders. However, data in noncholestatic cirrhosis are relatively scant. AIMS To determine prevalence and severity of low bone mineral density in noncholestatic cirrhosis and to investigate whether age, gender, etiology, severity of underlying liver disease, and/or laboratory tests are predictive of the diagnosis. ...

OBJECTIVES A longitudinal study was conducted to investigate the relationships of the change in radius bone mineral density for seven years with lifestyle, body measurement data and laboratory data. METHODS The subjects of this study were 191 female employees working in an LSI manufacturing factory in Japan. Bone mineral density was measured on the radius of their nondominant side using DXA (...

BACKGROUND/AIMS Calcium and vitamin D malabsorption in coeliac disease predispose to skeletal demineralisation. This study aimed to determine bone mineral density in patients studied in the first year after diagnosis of coeliac disease, and to detect changes in bone mineral density over the subsequent year. METHODS Lumbar spine and femoral neck bone mineral density was measured in 21 adults w...

OBJECTIVE The purpose of this study was to analyze the relationship between martial arts practice (judo, karate and kung-fu) and bone mineral density in adolescents. METHODS The study was composed of 138 (48 martial arts practitioners and 90 non-practitioners) adolescents of both sexes, with an average age of 12.6 years. Bone mineral density was measured using Dual-Energy X-ray Absorptiometry...

Background Improving peak bone mass and bone strength in the first years of life and enhancing it during young adulthood could prevent osteoporosis and fractures in the last years of life. We evaluated the prevalence of low bone mass in the lumbar and femoral neck and its associated factors in southern Iranian children. Methods This is a cross-sectional study on healthy Iranian children aged ...

background: revealing data on the role of vitamin d and calcium supplementation in bone health has led some to suggest that vitamin d and calcium treatment could also play a role in protecting bone against microgravity-induced mineral loss. objectives: the aim of the present study was to investigate the effects of vitamin d and calcium administration on microscopic and densitometric changes of ...

Loss of bone mineral density due to osteoporosis is the main cause of fragility fractures and leads to dropped quality of life and increased mortality. Disturbance of balance between bone formation and bone resorption is dangerous, can cause loss of bone mass and disruption of it's architecture. Correct development, achievement of peak bone mass and normal functioning of human skeleton depend o...

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, ...
