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 significantly longer in SGA group (P?
