Growth and development of term disproportionate small-for-gestational age infants at the age of 7 years.

Twenty-four term infants with disproportionate intrauterine growth retardation (SGA group) and 24 normally grown term infants matched for age, sex, birth rank and social class were followed from birth until 7 years of age. Both groups were free from perinatal complications and chronic diseases. The children in the SGA group continued to be underweight-for-height with a low ponderal index and a relatively small head circumference at the age of 7 years. Only minor shifts occurred in the individual growth curves since the age of 3 years. In 12 SGA children and 1 control multiple 'soft' neurological signs were found. Their grammar school teachers observed problematic behavior (hyperactivity, poor concentration and clumsiness) in 9 and academic problems in 5 of the 12 SGA children with neurological dysfunction. These findings indicate that disproportionate intrauterine growth retardation at term can have long-term effects on growth and development.
