WHOLE BODY MEASUREMENTS OF BONE AND SOFT TISSUE BY DEXA

本研究的目的是比较用于测量骨矿物质密度和软组织读数的两种仪器（这是目前使用的两种主要仪器）。 执行此操作是为了评估下一个 NHANES 数据收集工作的方法。 国家卫生统计中心要求研究者进行这种比较。 该地点将研究 50 名 20-80 岁的个体（另外还将研究来自 USCF 的 50 名个体）。 当天将进行扫描。 数据分析被清楚地概述，并且基于协议所附的对应关系，存在检测显着差异的能力。这项研究已顺利完成。 输入所有志愿者并分析数据。 该数据用于帮助国家健康检查调查确定是否在下一次 NHANES 调查中使用 Hologic 双能 X 射线吸收测定设备进行身体成分分析。

The objective of this study is to compare the two instruments (these are the two major instruments currently in use) listed for the measurement of bone mineral density and soft tissue readings. This is being performed to evaluate the methods for the next NHANES data collection effort. The investigator has been asked by the National Center for Health Statistics to perform this comparison. Fifty individuals aged 20-80 will be studied at this site (an addition 50 from USCF will also be studied). Same day scans will be performed. The data analysis is clearly outlined and based on correspondence attached to the protocol, the power to detect significant differences is present. This study was successfully completed. All volunteers were entered and the data analyzed. This data is used to help the National Health Examination Survey determine whether to use hologic dual energy x-ray absorptiometry equipment to perform body composition analysis in the next NHANES Survey.
