RESUMO

This study s objective was to evaluate the postnatal growth of very low birth weight (VLBW) newborns at the Neonatology Service in the Center for Integral Assistance to Women s Health, at the University of Campinas (CAISM - UNICAMP), prospectively following 179 neonates, without hydropsis, congenital anomalies or infection and not large for gestational age (LGA). All of them were fed according to the Service nutrition protocol, and discontinuation occurred due to severe clinical disturbances, hospital discharge or death. Using daily weight measurements, postnatal growth curves were traced, from birth up to 6th day of life^ and from the 7th to 49th day of life, for each neonate. General curves to each birth weight group, using the average values of the postnatal growth curves, and then compared to Dancis curves. Daily growth presented an initial period of loss that was more noticeable than Dancis , although also presented a posterior period with more accelerated gain. Another point of concern was the postnatal growth through weekly weight values, using corrected age. According to this method, for each neonate, weight curves were traced, consisted of more than three values, excluded the birth weight value. The average of the curves for the general population, the adequate (AGA) and the small (SGA) for gestational age were compared with data from the literature on intrauterine and postnatal growth curves. Head circumference and length were also studied in a similar method, as described above. Evaluation of growth, according to post-conception age, presented a different pattern from the one observed in the intrauterine growth curve, either to weight or length and head circumference, that is an initial period of postnatal growth with lower speed. Nevertheless, close to term, both weight and length presented partial recovery of the intrauterine values, while head circumference reached over its average values
