This review will focus chiefly on recently published studies utilizing air-displacement plethysmography (i.e. BOD POD) in geriatric populations. This innovative technology has been available commercially since 1995. As the test procedure is relatively easy to perform and quick, it may provide an improvement in body composition testing, especially in older individuals with poor ambulation and health.
This review will explain in a concise and detailed manner the underlying principles of air-displacement plethysmography specifically related to the BOD POD. Second, it will review the studies using this new technology in comparison with more commonly used techniques (hydrostatic weighing, dual energy X-ray absorptiometry, deuterium oxide, multi-compartmental models) for body composition analysis in geriatric populations. Third, it will provide a direction for future studies.
A review of the current body of literature in which air-displacement plethysmography was used is beginning to emerge with a clear picture. Although this technique is still new, it appears that air-displacement plethysmography is a valid and reliable alternative to more traditional body composition techniques, as indicated by small mean differences between techniques. This has special implications in a geriatric population because traditional techniques are difficult to perform in individuals with joint pain, ambulation issues, and overall poor health.
本综述将主要聚焦于近期发表的在老年人群中使用空气置换体积描记法（即BOD POD）的研究。这项创新技术自1995年起已商业化应用。由于测试过程相对易于操作且快速，它可能会改善身体成分检测，尤其是对于行走能力差和健康状况不佳的老年人。
本综述将以简洁且详细的方式解释与BOD POD具体相关的空气置换体积描记法的基本原理。其次，将综述在老年人群体身体成分分析中使用这项新技术并与更常用技术（水下称重法、双能X线吸收法、氧化氘、多室模型）进行比较的研究。第三，将为未来研究提供方向。
对目前使用空气置换体积描记法的文献进行的综述开始呈现出清晰的图景。尽管这项技术仍然新颖，但技术之间较小的平均差异表明，空气置换体积描记法似乎是比传统身体成分技术更有效且可靠的替代方法。这在老年人群体中有特殊意义，因为传统技术在有关节疼痛、行走问题和整体健康状况不佳的个体中难以实施。
