Abstract: Objective: To investigate the intelligent development of late preterm infants and its influencing factors, and to provide a theoretical basis for early intervention. Methods: Two hundred late preterm infants were enrolled, and 100 full term infants were served as controls. The intelligence development level was assessed by Gesell development schedules test, and the risk factors for influencing the development of intelligence were analyzed. Results: The average developmental quotient score of 200 late preterm infants was 94.5+6.7, and the abnormal rates of gross motor development, fine movement, verbal skills, social behavior and adaptability were 9.00%, 10.00%, 8.50%, 8.50%, and 9.00%, respectively. Multi factor logistic regression analsis showed that, very low birth weight (OR=2.235), low blood glucose (OR=2.002) and parental education level (OR=0.750) were associated with mental development in late preterm infants(P< 0.05). Conclusions: The late preterm infants are at high risk for mental development, abnormal rates are significantly associated with very low birth weight, low blood glucose and low parental education level.
