RESUMO
Objective To compare the growth velocity of low birth weight premature (LBWP),mature low birth weight (MBLW)and normal birth weight(NBW)infants and to explore the intervention mode for low birth weight (LBW)infants. Methods 1 133 Infants were divided into LBWP group,MBLW group and NBW group.The growth velocity of weight, height and head -circle were compared.Results The growth velocity of LBW group was greater than that of NBW group (P <0.05).Head circumference of LBWP group was the same as NBW group when they were 1 year old.The growth velocity of LBWP group was greater than that of MBLW group(P <0.05 )and the growth velocity of LBWP group was significantly greater than that of MBLW group when they were 1 year old (P <0.01).Conclusion LBWP infants have greater growth velocity potential than MBLW and NBW infants.It's necessary to pay more attentions to the growth velocity of MLBW infants.
