Immunocompetence is a sensitive and functional barometer of nutritional status.
Nutrition is a critical determinant of immunocompetence and risk of illness. Young children with protein-energy malnutrition exhibit increased mortality and morbidity, due largely to infectious disease. Recent work has demonstrated that undernourished individuals have impaired immune responses. The most consistent abnormalities are seen in cell-mediated immunity, complement system, phagocytes, mucosal secretory antibody response, and antibody affinity. Many of these immunologic changes occur early in the course of nutritional depletion and therefore can serve as sensitive functional indices of nutritional status.
