The World Health Organisation (WHO) recommends weight-for-length/height (WFL/H), represented as a Z score for diagnosing acute malnutrition among children aged 0 to 60 months. Under controlled conditions, weight, height and length measurements have high degree of reliability. In 1999, WHO defined severe malnutrition in children as a weight-for-height 1 below -3 SD2 (based on NCHS reference) and/or the presence of oedema (6). Experts in a meeting in 2005, (7,8) recommended to add MUAC less than 110 mm (in 6 to 60 month old children) as an independent diagnostic criterion. Degree of Malnutrition Mild (z score < -1) Moderate (z score -2 to -3) Severe (z score < -3) Etiology Illness related Not illness related, behavioural, socioeconomic Inflammatory State Present usually in malnutrition related to illness Absent usually in malnutrition related to starvation Pathogenetic Mechanism Starvation Hypermetabolism Malabsorption The z score is the standard deviation (SD) above or below the mean. A z score of 0 is the same as a 50th percentile, ± 1.0 plots at the 15th or 85th percentiles, respectively, ± 2 at roughly the 3rd or 97th percentiles. At birth, Josh’s z score was at about -3.7, or 3.7 SD below the mean. 2000 CDC growth charts to report growth metric percentiles and Z-scores on infants from 0 to 36 months of age.

Management of complicated severe acute malnutrition in children in resource-limited countries View in Chinese …"thinness" (corresponding to moderate malnutrition) is defined as a Z-score <-2 SD, and severe thinness (corresponding to severe malnutrition) is <-3 SD. Fix the chart on an even wall with the bottom of the chart touching the floor. Take the child's weight to the nearest 500 g and record. Locate the child's weight with your finger. Ask the caregiver to put the child under your finger against the wall chart. So, a z score of 0 is the equivalent of the 50th%ile or average of what you are measuring (weight, height, weight for height or BMI) for that age. A z score of +1 means your plots fall at the 15th%ile or 85th%Ile and a z score of +2 falls roughly at the 3rd or 97%Ile. These files contain the z-scores values for the z-scores of –2, -1.5, -1, -0.5, 0, 0.5, 1, 1.5, and 2 by sex (1=male; 2=female) and half month of age. For example, 1.5 months represents 1.25-1.75 months. The only exception is birth, which represents the point at birth.
