双能X线吸收法全身身体成分分析对诊断骨质疏松症的临床价值的探讨及研究

目的了解乌鲁木齐地区汉族人群随年龄增长骨密度的变化规律;确立全身身体成分分析用于临床及科研的价值;从骨密度的角度来分析"全身身体成分分析"测得的BMD与国际公认的单部位(前臂、腰椎、股骨近端)BMD的差异;帮助临床医生正确解读全身身体成分分析报告。方法采用DMS公司LEXXOS型骨密度仪对乌鲁木齐地区2300例汉族人群的全身身体成分(包括左侧肋骨、右侧肋骨、胸椎、腰椎、骨盆、左侧下肢、右侧下肢)进行精确测定,分析各部位相关数据对于诊断骨质疏松症的意义。结果全身身体成分分析是否可以用于骨质疏松症的诊断,不能一概而论,应视患者的具体情况,具体分析、具体对待。结论若除去左侧肋骨、右侧肋骨以外,其它部位(胸椎、腰椎、骨盆、左侧下肢、右侧下肢)的Z-score出现低值时,可考虑患者有低骨量骨病;当这些部位的T-score均出现低值时则可考虑骨量减少或骨质疏松症。而骨质疏松症的诊断还是以检查单部位(前臂、腰椎、股骨近端)骨密度为主。全身身体成分分析因为它特定的多个软件最主要应用于临床保健医学、体质测定、营养评定、运动医学等领域的科研及监测。

The exploration and research of the clinical value of whole body composition analysis on osteoporosis using double X-ray absorption method

Objective To investigate the alterative pattern of bone mineral density along with age in Urumqi residents,to establish the value of the body component analysis for clinical and scientific research,and to help clinicians to interpret the body component analysis report correctly.Methods The whole body composition of 2300 Han residents in Urumqi was measured using the dual energy X-ray absorptiometry(LEXXOS,DMS),including the left ribs,right ribs,thoracic spine,lumbar spine,pelvis,left leg,and right leg.The relevant data was analyzed for diagnostic value.Results The diagnostic value of body component analysis for osteoporosis could not be generalized.The situation of patients should be specifically analyzed and treated.Conclusion When Z-score of the whole body component decreases,except the left ribs and the right ribs,osteopenia can be possibly diagnosed.When T-score of the whole body component decreases,osteopenia or osteoporosis can be possibly diagnosed.The diagnosis of osteoporosis should rely on the results of BMD of positions including the forearms,spinal vertebra,and proximal femur.Because of the existence of multi-software specifically for the whole body composition analysis,it should be applied mainly on the medical care,physical fitness testing,nutritional assessment,sport medicine,and other fields.
