PIP: 761 infant weighing 1500 gms or less at birth were admitted to the Neonatal Intensive Care Unit at the Guatemalan Institute of Social Security between 1983-88. Cases with severe congenital or chromosomal anomalies were excluded. 386 infants survived this initial hospitalization. 150 completed 2 years and 65 completed 5 years of follow-up at a special multidisciplinary clinic. Follow-up visits were scheduled 1-3 months after discharge and subsequently at 4, 7, 10, 12, 15, 18, 21, and 24 months and every 6 months thereafter through age 5. The consultation focused on health protection, early diagnosis of growth or developmental delays, and prompt rehabilitation. 74 of 81 infants weighing 500-800 g died, as did 97 of 130 weighing 801-1000 g, 96 of 170 weighing 1001-1200 g, and 108 of 380 weighing 1201-1500 g. The proportion of very low birth weight infants increased from 7.6 to 11.7% of all births between 1983-88 and averaged 8.6% for the 6 years.
