Description: This data set includes data on 671 infants who had a very low birth weight, defined as being less than 1600 grams. The data were collected between 1981 and 1987 at Duke University Medical Center by Dr. Michael O'Shea, now of Bowman Gray Medical Center. This project was funded by a Clinical Epidemiology Grant from the Mellon Foundation.
Note that ALL these infants had very low birth weights, so if you are comparing infants with a relatively high birth weight to infants with a relatively low birth weight, even the relatively high birth weights are very low compared to normal infant birth weights.
Results of the study were published in M. O'Shea, D.A. Savitz, M.L. Hage, K.A. Feinstein: Prenatal events and the risk of subependymal / intraventricular haemorrhage in very low birth weight neonates. Paediatric and Perinatal Epdiemiology 1992;6:352-362.
