CAT scanners have been modified to reduce x-ray exposure, so this may no longer be a limitation. While all these techniques lack ease of use in the field, DXA at least appears to have the potential to serve as a new criterion measure to validate anthropometric equations.

studies could be limited to specific tests that prove to be most meaningful and reliable. Tests based on cytokine assays, especially those of the proinflammatory cytokines and related molecules excreted in urine, have great potential for adding important new diagnostic measures at a relatively inexpensive cost/benefit ratio.

Advanced methodologies for a wide assortment of immunological assessments are already available in research laboratories, but considerable effort may be required to adapt them for field use. This problem can be minimized by focusing on a small, select number of tests that will yield the greatest amount of clinical information.

COMMITTEE CONCLUSIONS These conclusions were developed in executive session and represent the views of the CMNR. • Methods of measuring body composition are relevant and important to the military to assure accuracy and fairness in the application of body composition measures to accession and retention of military personnel.

receiving significant support by federal and industrial funds should continue, and therefore, DoD investment is not recommended at this time. • Since military operations are frequently stressful and may be carried out in very hostile environments, it is important to understand the role that the body's immune function plays in helping the soldier cope and to consider ways in which immune responses may be controlled or enhanced to maximize the individual's ability to perform.
