This study reports on two aspects of outcome in a sample of infants whose birth weights ranged from 500 to 799 gm. First, maternal and early neonatal variables were analyzed by means of stepwise logistic regression. Five-minute Apgar score and initial pH were the only variables that predicted mortality at p less than or equal to 0.05. Second, the surviving infants were examined at ages ranging from 17 months to 7 years. The majority (72%) had neurologic and/or developmental examinations in the suspect or abnormal range and required rehabilitation or early intervention services.
