Methods for the measurement of nutrition impact and adaptation of laboratory methods into field settings to enhance and support community-based nutrition research

摘要

International nutrition will become increasingly concerned with evaluation of nutritional status at the community level to diagnose situations of risk for nutrient deficits and excesses, and to monitor the impact of remedial interventions. Advances in biologic concepts and technology (particularly miniaturization of assays) are assisting the creation of noninvasive, robust, and acceptable diagnostic tests of nutritional status for field settings. As with more complex and formal assays, the principles of accuracy, reliability, and construct validity need to be applied.
