8. Functional consequences

A number of functional consequences of undernutrition have already been touched upon. However, we have very little information about the extent to which mild or moderate degrees of deficit affect physical and mental functions, and whether the relationships are linear or have a threshold. In adults, the BMI is increasingly used as a measure of chronic energy deficiency. There is some evidence that when the BMI falls below a level of about 17, functional impairments begin to appear, e.g., increased absenteeism from work, and in women low birth weight of infants. In children we know that severe stunting is accompanied by delays in mental development, but the concomitants of smaller deficits in linear growth have not been studied. This subject presents a major challenge for future work.
