An 18-month follow-up study of growth-retarded neonates. Relation to biochemical tests of placental function in late pregnancy and neurobehavioural condition in the newborn period.
Serial estimations of maternal urinary oestriol, serum cystine aminopeptidase (S-CAP), and human chorionic somatomammotrophin (S-HCS) were studied prospectively in 29 pregnancies complicated by intrauterine growth retardation. The newborn growth-retarded infants were examined by neurological and behavioural techniques. Growth variables and neurological and developmental findings were compared with those in 18 healthy controls at 5, 10 and 18 months of age. The growth-retarded infants caught up with regard to body size from 5 months of age, although the severely retarded infants (birth weight less than or equal to -2 SD) differed from the controls with regard to weight and head circumference at 18 months of age. Abnormal maternal oestriol excretions were negatively correlated to weight and length during the follow-up period. Infants who had been severely growth-retarded at birth were neurologically below optimal level at 10 months of age, compared to the controls. There were no significant differences between the growth-retarded infants and the controls with regard to psychomotor development, as assessed by a screening test and by Griffiths' method. Significant correlations were found between abnormal biochemical placental tests (especially urinary oestriol and S-CAP) and psychomotor development. Significant correlations also appeared between neonatal orientation and motor behaviour and some Griffiths' scales at 18 months of age. No relationship was found between the neurological condition in the neonatal period and the neurological findings and development at follow-up.
