Air-displacement plethysmography holds promise as an alternative to more traditional body composition techniques, although our understanding of air-displacement plethysmography is less than complete. Specifically, factors that influence its validity and application in certain populations, for example children, the obese, and athletes, must be better understood. This review will summarize recent findings on the validity and precision of air-displacement plethysmography and will focus primarily on papers published since 2004, with particular attention on its use in infants.
The most significant recent findings in the air-displacement plethysmography literature are mechanistic in nature specifically dealing with measurement issues such as heat, moisture, clothing, and recently, inter-device variability.
It is important to recognize that air-displacement plethysmography can be a practical instrument in the evaluation of body composition in a wide range of populations. Therefore, based on the body of literature that has emerged, air-displacement plethysmography appears to be a suitable and reliable instrument in the assessment of body composition. Of particular interest is its use in pediatric and obese individuals, areas requiring further study. Research is also needed to help us better understand sources of measurement error.
空气置换体积描记法有望成为更传统身体成分测量技术的替代方法，尽管我们对空气置换体积描记法的了解还不够全面。具体而言，必须更好地理解影响其在某些人群（如儿童、肥胖者和运动员）中有效性和应用的因素。本综述将总结空气置换体积描记法有效性和精密度的最新研究结果，主要关注2004年以来发表的论文，特别关注其在婴儿中的应用。
空气置换体积描记法文献中最近最重要的研究结果本质上是机制性的，具体涉及热、湿度、衣物等测量问题，以及最近的设备间变异性。
必须认识到，空气置换体积描记法在评估广泛人群的身体成分时可以是一种实用工具。因此，基于已出现的文献，空气置换体积描记法似乎是评估身体成分的一种合适且可靠的工具。特别值得关注的是其在儿科和肥胖个体中的应用，这两个领域需要进一步研究。还需要开展研究以帮助我们更好地理解测量误差的来源。
