title: The effects of prenatal and perinatal complications on development at one year of age.
abstract: 35 variables descriptive of birth and obstetric complications, prematurity, maternal discomfort, and demographic status were studied for a sample of 322 infants. Factor analyses of these variables resulted in 7 major factors that were used to predict developmental status at 1 year of age for 233 of the subjects. Factors identified as "prematurity," "delivery and related variables," "ethnicity," and "complications" made significant independent contributions to Cattell DQ at 1 year. When Cattell DQs were corrected for the effects of gestational age, only delivery and related variables remained critical, confirming the importance of this factor for later development.
