Medical examination in nutrition surveys.
Pellagra was the most important deficiency disease used as a model for nutrition surveys, because its diagnosis depended on physical signs. By the mid twentieth century, laboratory tests improved the specificity of physical signs in diagnosis of deficiency disease. The author uses his experience in Panama to illustrate how attention to the details of a medical examination can improve accuracy and sensitivity of a nutrition survey.
