Decimal precision  

 

 

 Assessment of stunting

 
Z-score >-2: No stunting
Z-score >-3 and ≤-2: Moderate stunting
Z-score ≤-3: Severe stunting

 

 

 Assessment of wasting

 
Z-score >-2: No wasting
Z-score >-3 and ≤-2: Moderate wasting
Z-score ≤-3: Severe wasting

 
 

 
Notes
  • This calculator is based on the World Health Organization (WHO) growth standard.
  • Moderate malnutrition is defined as moderate stunting or wasting.
  • Severe malnutrition is defined as severe stunting, severe wasting, or edematous malnutrition.
  • Patients with edematous malnutrition (Kwashiorkor) should be considered to have severe malnutrition even if stunting or wasting Z-scores are not in the severe range.
  • At the extremes (>97th percentile or <3rd percentile), small differences in percentiles represent clinically important differences. At these extremes, the Z-score is a more precise reflection of how far the measurement deviates from the mean and is a useful tool for tracking changes.
  • For all LMS tables, the row in the table corresponding to the patient-specific value is found in the first column of the table; values to be used for L (the Box-Cox power), M (the median), and S (the generalized coefficient of variation) in the equation for Z-score are retrieved.
  • The accuracy of the calculation can be assessed by viewing the graph of height-for-age percentiles for this sex and age group in UpToDate.
  • Z-scores may be used to do a table lookup for the corresponding percentile in the Normal table percentiles for Z-score table (below). Numbers along the left side (Y-axis) of the table represent the first number and first decimal place of the Z-score, while the numbers along the top (X-axis) of the table represent the second decimal position of the Z-score.

 
Equations used
 
Z_Score_Height_for_Age = ((Height/M)L - 1) / (L * S)
Z_Score_Weight_for_Height = ((Weight/M)L - 1) / (L * S)
Height-for-age percentile = ZtoPercentile(Z-score height-for-age)
Weight-for-height percentile = ZtoPercentile(Z-score weight-for-height)
