Using the Waterlow criteria, weight-for-length is an index of which type of wasting?

Explanation:
Weight-for-length is used to identify wasting, which signals acute malnutrition. Because length (or height) changes slowly, a low weight-for-length mainly reflects a recent weight loss or short-term energy deficit from inadequate intake or acute illness. That makes it an indicator of acute wasting. Chronic malnutrition shows up as stunting (low height-for-age), reflecting longer-term inadequate intake. Wasting due to illness or hypoalbuminemia isn’t a separate category in this framework; the distinction here is that weight-for-length monitors acute depletion rather than long-term growth failure.
