Early growth and development in low-birthweight infants following treatment in an intensive care nursery.
Sixty-seven appropriate-for-date infants with gestations less than 33 weeks were followed for 12 months after their term dates. All had been born after September 1970. None received hypercaloric alimentation as neonates. Growth from the expected date of delivery was compared with that of 24 normal full-term infants and with accepted growth standards. The boys did not differ from the controls or the standard in mean weight, length, and head circumference, in weight and height indices, or in velocity of weight and linear growth. The girls had a slower velocity of weight growth for the first six months and had significantly lower weight indices at 12 months than did their controls. Velocity of linear growth, height indices, and mean length and head circumference for the girls were similar to those of the control standards. Gross central nervous system defects occurred in 22.5% of the boys but in none of the girls. More than one half of the abnormalities were hydrocephaly. The mean post-conceptional developmental quotient was 110 for the girls and 108 for the boys.
