Correlation of asphyxia and other risk factors with outcome: a contemporary view.

The relationships between 14 maternal/prenatal, 24 perinatal and 12 asphyxia-related variables and outcome at 40 weeks, nine, 18 and 36 months were evaluated in a sample of 608 children enrolled in the multi-center National Heart, Lung and Blood Institute Collaborative study. Correlations were weak generally, although they tended to be stronger for perinatal variables and neurological outcome at 36 months. When the maternal/prenatal and perinatal variables (medical/biological), the SES-Composite Index (environmental/psychosocial) and the Early Neuropsychologic Optimality Rating Scale-9 (behavioral/developmental) were used as optimality scales, prediction was enhanced; however, it appeared that the environmental/psychosocial and behavioral/developmental scales were more predictive of 36-month outcome than were medical/biological variable groupings.
