Abstract:
The body composition (BC) describes the different components that makeup the human being and refers to the proportion of fat and fat - free mass inthe body. Aging processes are natural complex physiological alteration in thebody associated by weakness of the structure and functions in the organs.The alterations in body composition that occur with the aging process nothappen homogeneously. Although there are various techniques forassessment of body composition in research and clinical settings, DualX - ray absorptiometry (DXA) is the most commonly used methods forexamination and also preferred choice and golden clinical tool for thediagnosis of osteoporosis and assessment of its severity. This equipment isnoninvasive, widely available and currently the scanning of hip and spineused as the gold standard by a major number of clinicians. In recent years,there has been an increasing interest in BC measurement to assess the health.This is the first study in Iraq to assess healthy subjects.Objectives : to evaluate the changes of bone mineral density and fatty massand lean mass in postmenopausal period and to correlate them withanthropometric measurements. Also to correlate between BMD with serumcalcium, phosphate and alkaline phosphatase.Subjects and methods : This cross - sectional study was conducted at DXAUnit in Baghdad Teaching Hospital from November 2016 to December2017. Data were collected from (120) postmenopausal female subjects and(120) premenopausal female subjects with total of 240 females from age of40 - 69 years were randomly selected from the patients attending DXA unit inBaghdad Teaching Hospital. The postmenopausal female subjects weredefined as individuals with menopause at least one year since the last naturalmenstruation. Osteoporosis was diagnosed according to WHO criteriaIIT - score was used for postmenopausal subjects and Z - scores forpremenopausal subjects. Women were excluded from the study if they anycondition may affect the BMD or other constituents of BC.Results : a highly significant lower BMD of lumbar spine and both femurswere found in postmenopausal group. Although the mean of areas of ribs, lumbar spine, pelvis, legs and total body fat mass were higher in postmenopausal subjects but no significantly differences of body fat mass g̸cm² measured by DXA between the postmenopausal and premenopausal subjects. A highly significant difference of LM g ̸cm² measured by DXA between the postmenopausal and premenopausal subjects (p - value0.0004 - 0.001) in measurements of total LM and anatomical areas. Significant effects were found of total FM and total LM on BMD of lumbar spine and neck of both femurs in postmenopausal subjects but LM had more effect than FM.Conclusion : A highly significant lower BMD and LM were found with increased adiposity among postmenopausal women. Both FM and LM affect BMD of lumbar spine and both femurs but LM had more effect
