In the Waterlow criteria, weight for length is evaluated as an index of which form of malnutrition?

Explanation:
Weight-for-length (or weight-for-height) is used to gauge wasting, which reflects acute malnutrition. It compares how heavy a child is for their actual length, capturing recent weight loss or a short-term failure to gain weight due to inadequate intake or illness. This contrasts with chronic malnutrition, which shows up as stunting—low height-for-age—indicating long-term growth deficits. Biochemical factors like hypoalbuminemia aren’t the index used in the Waterlow scheme, and while illness can drive acute weight loss, the classification itself is about current body proportions rather than a specific illness.
