title: High increments of overweight along with low length-for-age growth during the first 24 months of life.
abstract: BACKGROUND
  It has been reported that children nursed in orphanages loose one month of lineal growth for every three months they spend in the orphanage.
  
  
  OBJECTIVE
  The purpose of this study was to evaluate the daily variation of weight- for- length and length-for-age among infants under 24 months of age, living in a temporary public orphanage in Mexico.
  
  
  METHODS
  Ninety children from 0 to 24 months of age, who were institutionalized at an orphanage, were assessed during a three month period. Upon arrival their height and weight were measured daily, Monday through Friday. Daily growth velocity for weight and length was calculated. Length-for age (LAZ) and weight-for-length (WHZ) age z- scores were calculated based on WHO criteria. Risk of overweight (ROW) and overweight (OW) were classified using the WHO criteria.
  
  
  RESULTS
  The increments of daily weight were lower than the normal range (9 g daily), but the ROW and OW increased from 10% and 3% at the beginning of the study to 14% and 11% at the end. At the end of the follow-up, WHZ was inversely associated to length (cm/day) velocity (r = -302, p < 0.01). Although a significant increase in ROW and OW was observed, at the end of the study, 31% of the children showed signs of stunting (-2 SD in length-age) and 5% remained emaciated (-2 SD in weight-length).
  
  
  CONCLUSIONS
  Children living in an orphanage showed reduced increments of weight and length-for-age, as well as a reduced length velocity and an increased ROW and OW.
