A z-score is the number of standard deviations below or above the reference median value. Anthropometric indices (Height for Age Z-score(HAZ); Weight for Height Z-score (WHZ) and Weight for Age Z-score (WAZ)) were calculated using the Epinut 2.0 (EpiInfo library by Chris D. Smith; CDC Division of Surveillance and Epidemiology, USA; EpiInfo-6.04 software package).
