Abstract
Body composition measurements from DXA have been available since DXA technology was developed 30years ago, but are historically underutilized. Recently, there have been rapid developments in body composition assessment including the analysis and publication of representative data for the US, official usage guidance from the International Society for Clinical Densitometry, and development of regional body composition measures with clinical utility. DXA body composition is much more than whole body percent fat. In this paper celebrating 30years of DXA for body composition, we will review the principles of DXA soft tissue analysis, practical clinical and research applications, and what to look for in the future.
摘要
DXA 技术 30 年前问世以来，其身体成分测量结果便已可得，但历史上并未得到充分利用。最近，身体成分评估领域发展迅速，包括美国代表性数据的分析和发布、国际临床骨密度学会的正式使用指南，以及具有临床实用性的区域性身体成分测量方法的发展。DXA 身体成分测量结果远不止全身脂肪百分比。在这篇庆祝 DXA 身体成分 30 年的论文中，我们将回顾 DXA 软组织分析的原理、实际的临床和研究应用，以及未来的发展方向。
