Definition: Severe loss of weight [wasting] in children or adults, or lack of weight gain in children leading to an observe
d weight that is at least 3 standard deviations below the mean valu
e for the reference population (or a similar loss expressed
through other statistical approaches). When only one measurement is available, there is a high probability of severe wasting when the observed weight is 3 or more standard deviations below the mean of the reference population.
