The equation of z-score (Z) calculated is : Z ={(X/M)*L -1}/(L*S). [Where, X=height/weigh/BMI, L, M and S are the age specific values of appropriate table corresponding reference populations]. The equation of z-score (Z) calculated is : Z = { (X/M)*L -1}/ (L*S). [Where, X=height/weight/BMI, L, M and S are the age-specific values of appropriate table corresponding reference populations Weight-for-age z-score distribution for children under 5 years, pre A and post B intervention. WAZ: Weight-for-age z-score (WAZ) The vertical bars represent measured data, the solid line represents the expected distribution of z-scores, and the dashed line represents ±2 standard deviations. Birth to 2 years (z-scores) Z-scores (BMI in kg/m 2) Year: Month Month L M S -3 SD -2 SD -1 SD Median 1 SD 2 SD 3 SD 0: 0 0 -0.3053 13.4069 0.09560 10.2 11.1 12.2 13.4 14.8 16.3 18.1 0: 1 because the BMI-for-age for Birth to 2 years is based on length. For children 2 to 5 years measured lying down, convert length to height by subtracting 0. Height-for-age, weight-for-height and weight-for-age Z-scores are calculated using the 2006 WHO child growth standards recommended for international settings . Children are considered stunted when they have height-for-age z-score below two compared with the WHO Child Growth standards median of same age and sex.
