“…The result was better than the percentage reliability of 2.3% we previously obtained on a sample of younger infants (Gartner et al, 1994). On the other hand, the value of our technical error of measurement was somewhat higher than values (below 7.5 O) obtained by Vettorazzi et al (1994) on a series of 10 measurements on four infants.…”

“…The need for standardization of electrode placement in BIA in young children has been reported previously (Gartner et al, 1992), and the placement of the sensor electrodes represents a high source of error in the BIA method. As in our previous studies (Gartner et al, 1994) and in studies by another team using BIA in malnourished children Vettorazzi et al, 1990Vettorazzi et al, , 1994, we chose to place the signal electrode on the dorsal side of the wrist and the sensor electrode 6 cm along the forearm; the leg signal electrode was placed on the dorsal side of the ankle and the sensor electrode 6 cm away in the pre-tibial region. By connecting the analyser clips to the electrodes, electrical current passed through the whole body.…”

Objective: To evaluate body composition changes using bioelectrical impedance analysis and skinfold thickness measurements in infants from tropical areas who become stunted between 4-18 months of age. Design and measurements: Follow-up study. Extracellular water to total body water ratio index (length 2 /resistance at low to high frequency), peripheral fat (tricipital and subscapular skinfold thickness), and length-for-age index were studied at 4 and 18 months of age. Settings: Low-income areas in four tropical regions (Congo, Senegal, Bolivia and New Caledonia). Subjects: Infants were included in the analysis provided they were neither stunted nor wasted at 4 months. Two groups of infants were compared, those that were stunted at 18 months (n ¼ 61) or not (n ¼ 170). Results: The extracellular water to total body water ratio index and the sum of skinfold thickness measurements were similar in the two groups at 4 months, and only the extracellular water to total body water ratio index was significantly different at 18 months. When no stunting appeared between 4 and 18 months, the change in the extracellular water to total body water ratio index was not linked with variations in length-for-age, and presented the expected pattern of variation in body water compartments. When stunting occurred, variation in length-for-age was related to significant changes in the extracellular water to total body water ratio index, the biggest increase in the proportion of extracellular water being found in the most stunted infants. Variations in the sum of the two skinfold thickness measurements presented the expected pattern for the 4-18 months growth and did not differ between the two groups. Conclusions: Multifrequency resistances suggested that stunting was associated with a lack of the expansion of the intracellular compartment that is expected during normal growth of cell mass, together with preserved fat mass.

Body Composition Measurements during Infancy

Infancy is the period of most rapid postnatal growth and is accompanied by major changes in body composition (BC). There are many challenges to successfully measuring BC of infants in vivo, which include the inherent limitations in the underlying assumptions for each technique. The small body mass and rapid nonuniform changes in body parts, that is, the components of BC during infancy, can strain the technical limits of all methods. Many techniques for in vivo BC measurement used in older people have been applied to infants. However, the vast majority of them either are difficult to adapt for widespread use in infants, or the roles and limitations for using them during infancy are ill‐defined because of limited or no critical validation and cross‐calibration studies. Based on validation data from animals, well‐defined methodological issues in data acquisition and analyses, availability of normative data, and pertinent accuracy and precision of the technique to allow us to determinate clinically relevant changes in BC within a reasonable time interval, three techniques appear to be most suitable for in vivo BC measurement in infants. Anthropometric measurements can be used in field studies or for group comparisons, and total body electrical conductivity (TOBEC) and selected dual‐energy X‐ray absorptiometry (DXA) measurements can be used to compare BC in individual infants. DXA has the advantages of being able to measure bone mass and the potential to be adaptable to the widely available existing instruments. However, regardless of the techniques used in measuring BC in infants, meticulous attention to details in data acquisition and data analysis, and a knowledge of the limitations of the particular technique are the prerequisites for generating valid data.
