Abstract: Objective To analyze the influence of preterm on physical growth and neuromotor development in infants, in order to provide evidence for improving motor development. Methods A total of 408 preterm infants with detailed case data in Neonatology Department of Qinzhou Maternal and Child Health Care Hospital were enrolled in this follow-up study. The head circumferences and body weights at corrected age of 40 weeks, 6 and 12 months were collected. Also, the score of Neonatal Behavioral Neurological Assessment (NBNA) at corrected age of 40 weeks and the development quotient in Gesell Developmental Scale at gestation-adjusted age of 6 and 12 months were collected. Comparison on physical growth and neuromotor development between physical growth retardation group and normal growth group was made. Results The incidence of physical growth retardation at corrected age of 40 weeks was the highest (21.8%), and was significantly lower at the age of 12 months than that at the age of 6 months. The incidence of impaired gross motor development at corrected age of 12 months was significantly lower than that at corrected age of 6 months (7.6% vs 16.4%). The infants with physical growth retardation had significantly higher incidences of neuromotor developmental delay at the three time points (P＜0.05). Conclusions Most preterm infants had achieved catch-up growth in physique and good development in neuromotor at corrected age of 12 months. Physical growth retardation at corrected age of 12 months is a risk factor for abnormal gross motor development.
