Mineral Density and Quantity of Bone, Parameters of Body Composition in Postmenopausal Women

Abstract

In diagnostic of osteoporosis the golden standard is bone mineral density, though X-ray densitomenry parameters not always determine risk for osteoporotic fractures. That is why new methods are being looked for to find the parameters not only mineral density, but rather quantity of bone. One of theses methods is trabecular bone score. As general weight of body includes fat and lean mass some researchers tried to determine their role in development of structural and functional impairments in bone, however there is no clear answer to this question: while some scientists considered fat mass as a basic factor of protection from fractures, other ones decided that lean mass is more connected with mineral density of bone tissue. The aim of study was to investigate parameters of quantity and density of bone of spine, neck of femur and body composition depending on the postmenopausal period; to study connection between fat mass and mineral density and quantity of bone. Materials and methods. The observed females were divided into the groups: premenopausal women and women with postmenopause of various duration (early, middle, late). There were conducted a general clinical observation of a patient and investigation of mentioned above parameters using X-ray densitomentry General Electric. Results. Quantity of bone (TBS) and bone mineral density significantly decrease depending on postmenopausal period. Fat and lean masses do not significantly change. In the middle and late postmenopausal periods bone mineral density of the spine and hip neck increase while fat mass increases.
