Abstract: Objective To explore the features of physique and motor development of preterm infants at the corrected age of 18 months and provide the theoretical basis for the improvement of their health related quality of life. Methods A prospective cohort study was performed from 2012 to 2015 at the following-up center of high-risk children in Maternal and Child Health Care Hospital,with 174 preterm infants and 183 term infant as the control group.Physique and motor development parameters were compared at the corrected age of 6,12 and 18 months,respectively. Results Preterm infants developed statistically significant worse on weight,length and head circumference at the corrected age of 6 months (P<0.01).Although,there was no difference in gross motor scores for the preterm infants at corrected age of 12 and18 months compared with the term infants.However,the preterm infants hadn't caught up with especially those who was small for gestational age (P<0.05) in the term of fine motor development and language and person society and adaptive behavior. Conclusion Preterm infants at the corrected age of 6 months hadn't caught up with the term ones,especially growing potential of who was small for gestational age was less than those appropriate for gestational age.Adequate nutrition and intelligent training for the preterm infants at the early stage might have potential value on the improvement of their life qualify.
