Abstract：Objective To explore the variation of weight for age Z score in preterm infants with extrauterine growth restriction (EUGR)during the hospitalization.MethodsData of the premature infant from the Neonatal intensive care unit of Huai′an Maternity and Child Healthcare Hospital from December 1,2010 to November 30,2013 were collected retrospectively.The criteria for enrollment were gestational age <32 weeks,within the first 24 hours of life and survived when discharged,and hospitalization period ≥2 weeks.With the criteria,all of the premature infants were divided into extrauterine growth restriction (EUGR) group and non-EUGR group.And then,WAZ score count of each specific group was described to observe their growth situation during the hospitalization.ResultsPreterm infants with EUGR were 122 cases,the incidence of EUGR assessed by weight was 40.7%.WAZ scores of the EUGR group and non-EUGR group were almost negative. Z score of the EUGR group was lower than that of the control group.All of the WAZ scores were showed significant difference (Z=10.72,11.00,11.47,10.72,8.91,14.42 respectively,P<0.05) between the EUGR and non-EUGR group in each observing time,such as at birth (-0.83±0.37,-0.25±0.39),the 1st week (-1.16±0.35,-0.54±0.43),the 2nd week (-1.14±0.35,-0.46±0.46),the 3rd week (-1.21±0.34,-0.58±0.39),the 4th week (-1.35±0.41,-0.65±0.42),and at the discharged time(-1.68±0.38,-0.52±0.44).ConclusionsThe weight for age Z score in preterm infants with EUGR show a progressive decline.The WAZ score′ variation tendency have some clinical significance to prevent EUGR.
