What’s a Z-Score ?

Ans: Nutritional status may also be expressed in terms of SD score of an anthropometric index such as WH. This score, also known as Z score, invitation of a nutritional status for NCHS reference values.

SD core = Individual’s value –median value of reference population
SD value of reference population
AWA and ZHA can be calculated in a similar way. If the individual value is greater than the median, then the value of + 1 SD taken to calculate the SD value of reference population:

For WA and WH : 1 Z score unit is about 10% of the median, except in infants <6 months of age.
For Ha : 1 Z score unit is about 5% of the median.

Malnutrition is defined as less than 2 standard deviations from the median (<- 2 z scores).
WH<-3 z is severe wasting
HA<-3 z is severe stunting
WA<- 3 z is severe underweight.
