A new method for the estimation of body composition in humans, called infrared interactance, is discussed. Infrared interactance is based on the principles of light absorption, reflection, and near-infrared spectroscopy. Body composition (percentage fat) was estimated in 53 adults (23 to 65 yr of age) by infrared interactance and compared to results from deuterium oxide dilution (r = 0.94), skinfold (r = 0.90), and ultrasound (r = 0.89) measurements. The method is safe, noninvasive, rapid, easy to use, and may prove useful to predict percentage body fat, especially in the obese.
本文讨论了一种用于估计人体身体成分的新方法——红外交互作用法。红外交互作用法基于光吸收、反射和近红外光谱原理。通过红外交互作用法对53名成年人（年龄在23至65岁之间）的身体成分（脂肪百分比）进行了估计，并与氧化氘稀释法（r = 0.94）、皮褶厚度法（r = 0.90）和超声法（r = 0.89）的测量结果进行了比较。该方法安全、无创、快速、易于使用，可能在预测身体脂肪百分比方面很有用，尤其是对于肥胖者。
