The changes in protein and energy intakes and weight in 2 weeks after birth in appropriate for gestational age ;and small for gestational age preterm infants with gestational age less than 34 weeks / 临床儿科杂志

ABSTRACT

Objective To investigate the changes of protein and energy intakes and the z-score of weight for age in appropriate for gestational age (AGA) and small for gestational age (SGA) preterm infants with gestational age less than 34 weeks. Methods The data from 314 hospitalized premature infants ( 268 cases of AGA and 46 cases of SGA) during January 2012 to December 2014 were retrospectively collected. The intakes of protein and energy and the changes of weight within 2 weeks after birth were compared. Results Compared with AGA group, the hospital stays, durations of parenteral and enteral nutrition and total enteral nutrition, and time to achieve full dose feeding were signiifcantly longer in SGA group (P?birth in SGA group was obviously lower than in AGA group;the protein intakes on day 6 and 8 in SGA group was also obviously lower than in AGA group (P?weight gain was signiifcantly higher in SGA group than that in AGA group (P?birth. Moreover, the z-score of weight for age at 2 weeks was lower in SGA group than that in AGA group (P?growth velocity in SGA premature infants was faster than that in AGA premature infants with gestation age lower than 34 weeks after recovery of birth weight. There was catch-up growth to some extent. However, the growth of SGA and AGA premature infants need to be improved.
