Objective To evaluate the growth and neurobehavioral development of very low/extremely low birth weight infants in the first year after birth, so as to provide evidence for early intervention. Methods A total of 222 very low/extremely low birth weight infants admitted to Nanjing Maternal and Child Health Care Hospital from August 2014 to July 2017 were followed up.Their growth and neurobehavioral development at 3, 6 and 12 months of corrected gestational age were evaluated.The infants were divided into different groups according to birth weight(≤1 000 g, 1 000<-1 500 g) and gestational age(≤28 weeks,＞28 weeks). T test and chi-square test were used for statistical analysis. Results The height, weight and head circumference increased with the increasing of age (40 weeks and 3, 6 and 12 months).There were no statistically significant differences in height, weight and head circumference in different birth weight groups and gestational age groups(P＞0.05).In terms of Gesell Scale, scores of each dimension increased gradually with age.And there were no statistically significant differences in five regions of the Gesell Scale in different birth weight groups and gestational age groups in infants at the age of 6 and 12 months old(P＞0.05). Conclusions Intrauterine retardation and neurobehavioral development lag in very low/extremely low birth weight infants can gradually catch up with age.And it is necessary to build up a standardized follow-up system.
