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… Expand

Near infrared interactance: Validity and use in estimating body composition in adolescents
Abstract Near Infrared Interactance (NIR) is a non-invasive, simple and rapid method of assessing percent body fat, but its possible use and validity has not been determined in adolescents. This… Expand
Total body fat estimations by near-infrared interactance, A-mode ultrasound, and underwater weighing.
TLDR
The Wherry-Doolittle test selection method was utilized to predict percent of total body fat (%fat) from either ultrasound or NIR data with anthropometric measurements, optimizing for the fewest number of data points which correlated highly with UWW results. Expand
The measurement of body composition by infrared interactance: An evaluation
Abstract The purpose of the present study was to investigate the validity of commercial instrumentation using near infrared interactance (NIRI) to predict total body fat. 169 adult men and women,… Expand
A near-infrared interactance model for the estimation of infant body composition
TLDR
A potential model for using near-infrared interactance (NIR) features for the estimation of infant fat mass and the deuterium dilution method as the reference method is developed and evaluated, demonstrating the potential of NIR to capture variability in body composition. Expand
Estimation of body composition of pigs by a near-infrared interactance probe technique
red (NIR) interactance was evaluated as a potentially new method for estimating live body and carcass composition of pigs. Using a surface placed fiber optic probe, measurements of the live animal… Expand
Reliability of near-infrared interactance body fat assessment relative to standard anthropometric techniques.
TLDR
The NIR method has good repeatability, with low intra- and interobserver variability, provided that readers are carefully trained, however, the NIR device offers little advantage in reliability over conventional measures of adiposity such as waist girth or BMI, and requires additional input of weight, height, frame size, physical activity level, age, and gender data.

Development of Diffuse Optical Spectroscopic Imaging (DOSI) for Quantitative Determination of Body Composition
Author(s): Reilly, Drew | Advisor(s): Tromberg, Bruce J | Abstract: Body composition and tissue hydration are critical parameters that play an essential role in each person’s health status and… Expand
Comparison of body composition measured by total body potassium and infrared interactance.
TLDR
As shown by repeated TBK measurements over a 22-year period in these same volunteers, this technique is reliable: the IRI assessments did not come to a close fit with TBK. Expand
The performance of an infra-red interactance instrument for assessing total body fat.
TLDR
It was noted that the infra-red interactance instrument yielded a very narrow range of body fats in females in comparison with the other techniques, and it is essential that these differences are reconciled beforeinfra- red interactance takes a significant role in body composition analysis. Expand

TLDR
Measurement of body density or of total body K or oftotal body water allows a calculation of the relative proportion of these two compartments in the body and therefore also of the total fat content. Expand

DENSITOMETRIC ANALYSIS OF BODY COMPOSITION: REVISION OF SOME QUANTITATIVE ASSUMPTIONS *
TLDR
It is shown that in a system consisting of two additive components which are mixed but the densities of which are known, the determination of the density of the system allows one to calculate the proportional masses of the two components. Expand

The data support the concept that the comparatively low specific gravity of fat makes the measurement of the specificgravity of the body mass valid for the estimation of fat content. Expand
