Undernutrition and severe acute malnutrition in children is measured in terms of z- scores or No. of standard deviations in WHO nomenclature
AUTHOR DEFINES MODERATE AND SEVERE UNDERNUTRITION AS FOLLOWS:
Moderate acute malnutrition
Low weight for height/length (<−2 to ≥−3 standard deviations of median WHO child growth standard)
Severe acute malnutrition
Very low weight for height/length (<−3 standard deviations of median WHO child growth standard) .
Here we would ask what is subclinical (mild) acute malnutrition.
We furthermore add that -2 standard deviation is -2 z-scores and -3 standard deviations is -3 z scores. And zero SD is mean or median whatever in usage.1
