title: [Follow-up of infants with birth weight under 1,500 g].
abstract: A prospective study of 199 children with birth weight less than 1,500 g was done. 86 boys and 113 girls, 141 (71%) adequate for gestational age and 58 (29%) small for gestational age. At follow-up 43 (21.6%) infants were lost to control, 17 (7%) moved to other places and 7 (3.5%) died in the first year of life. In the first year of life, infants whose birthweights were adequate for gestational age had been hospitalized more frequently and the small for dates showed higher percentage of undernutrition. After the second year of life, it was possible to know the impairment. It was found 7.4% of cerebral palsy, 2.9% of hipoacusia and 2.2% of retinopathy of prematurity, these diagnosis were most frequent in children that were adequate for gestational age. We concluded that small for dates infants are at risk of undernutrition and that those adequate for gestational age are at risk of permanent sequelae.
