Neurological follow-up of small-for-gestational age newborn infants. A study of risk factors related to prognosis at one year of age.
To examine the relative importance of some risk factors and neurological prognosis in the first year of life, 37 small-for-gestational age newborns were followed prospectively to 1 year of conceptional age. An abnormal neurological examination was found in 51.3% of the newborns and, at 12 months, 32.5% were still considered abnormal. Only 8.1% of the group had severe neurological sequelae at 1 year of corrected age. The developmental tests showed little changes during the first year, with abnormality rates varying from 16.1 to 25%. The following risk factors were analyzed concerning their relation to neurological and developmental abnormalities: high-risk pregnancy, maternal hypertension, social class, pre-term birth, neonatal asphyxia and weight and height less than 2.5 percentile at the age of 1 year. The statistical analysis showed a high correlation between subnormal weight gain and neurological (p = 0.0001) and developmental (p = 0.001) abnormalities at 1 year. None of the other risk factors were statistically related to neurological prognosis at 1 year.
