Exercise is commonly recommended in the prevention and management of osteoporosis. The most common method to monitor bone mass and its response to interventions is bone densitometry. While closely associated with risk of fracture, densitometry-derived areal bone mineral density (aBMD) does not provide a reliable indication of bone geometry or morphological adaptation to stimuli. In fact, the ef...

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...

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. ...

Background: The menopausal transition called perimenopause, happens after the reproductive years, and isspecified with irregular menstrual cycles, perimenopause symptoms and hormonal changes. Women going throughperi menopausal period are vulnerable to bone loss.Osteoporosis is one of the most common debilitating metabolic bone diseases ,especially in the women almostaround 50 years .This study ...

The goal of this chapter is to describe the underlying principles and error sources associated with X-ray based bone densitometry methods used to assess the central skeleton. The first portion of the chapter focuses on projectional densitometry measurements which are most widely used in the clinical setting. The concepts of single and dual photon absorptiometry are used to provide a simple and ...

OBJECTIVES Osteoporosis is a systemic skeletal disease with a consequent increased risk of fracture, decreased quality of life and economic burdens for both the patients and health care system. While Dual energy X-Ray absorptiometry remains the gold standard for assessment of bone mineral density, it cannot be requested for all patients for obvious reasons. By determining other variables that m...

This study aimed to evaluate the bone mineral density (BMD) of post-menopausal women with previous pre-menopausal hysterectomy including bilateral ovarian conservation compared to a group of non-hysterectomized women with natural menopause. Data from a cross-sectional study of 30 pre-menopausally hysterectomized women evaluated in the post-menopause were compared with 102 naturally post-menopau...

Glucocorticoids, widely used in inflammatory disorders, rapidly increase bone fragility and, therefore, fracture risk. However, common bone densitometry measurements are not sensitive enough to detect these changes. Moreover, densitometry only partially recognizes treatment-induced fracture reductions in osteoporosis. Here, we tested whether the reference point indentation technique could detec...

OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided into four groups of 15 segments each and demineralized in an aqueous 0.5 N hydrochloric aci...
