title: Early and Late Outcome of Premature Newborns with History of Neonatal Intensive Care Units Admission at 6 Years Old in Zanjan, Northwestern Iran.
abstract: OBJECTIVE
  Premature birth is an important factor for mortality and morbidity of neonates. This study was designed to evaluate the outcome of preterm neonates who needed neonatal intensive care (NICU) hospitalization after 6 yr at their entrance to the school.
  
  
  METHODS
  This cross sectional study was conducted on premature neonates consecutively hospitalized in NICU of Valie Asr Hospital (the Academic Pediatric Hospital, Zanjan, Northwestern Iran) from September 2001 to September 2003. All children with a history of prematurity and NICU treatment were evaluated at their entrance to the school. Demographic findings, clinical examinations, IQ test, hearing and visual acuity exams were recorded.
  
  
  RESULTS
  From 179 neonates, 78 (43.6%) survived and were discharged from hospital. Fifty-four of them were available and entered first grade in primary school. Only one case had severe mental retardation. One case had severe retinopathy of prematurity (ROP). Hearing abnormality was not detected in any case. There was no significant relation between IQ score, visual as well as hearing findings and gestational age.
  
  
  CONCLUSIONS
  We did not find significant disability in the outcome of surviving infants. This could be explained by the high mortality rate of neonates during hospitalization.
