RESUMO
Objective To validate the practical value of zhang-lu index(ZLI) in evaluating the physical growth of neonates.Methods Collecting the data of body weight,height and head circumference from 413 neonates,the results of ZLI were calculated according to the ZLI expression,then through the original date coming from 31 small for gestational age(SGA),65 large for gestational age(LGA) and 317 appropriate for gestational age(AGA),ZLI was compared with the conventional method of body weight for gestational age.Results 1.Compared with the method of body weight for gestational age,the sensitivity was higher than the result validated by the nation.The diffe-(rence) was significantly(P0.05).2.The results of ZLI of neonates in Huaihua city were larger than the reference given by the national of neonatal scientific research associate;The differences were significantly(P
