Assessment of Undernutrition Among the Under-5 Children in a Slum of Kolkata: A Comparison Between z Scores and the Conventional System

Background. This cross-sectional study was done to assess undernutrition among children under the age of 5 years in a slum of Kolkata (n = 188) and to compare these results with z score and the conventional Indian Academy of Pediatrics (IAP) system.
