Abstract

Objective To analyze the intelligence development of preterm with different gestational ages,in order to provide suggestions for healthcare of premature infants. Methods A total of 2 579 children aged 6-24 months in Guangzhou Women and Children's Medical Center were enrolled in this study from February 2012 to December 2015. And the participants were divided into four groups according to gestational age,including moderate preterm (MPT) (32^+0/7-33^+6/7weeks),late preterm (LPT)(34^+0/7-36⁺⁶weeks),early term (ET)(37^+0/7-38⁺⁶weeks) and full-term (FT)(39^+0/7-41⁺⁶ weeks) infants. Gesell development Scale was used to assess the neurodevelopment of participants,and the difference among four groups were compared. Results Compared with those born full term,the risk of neurodevelopmental delay in MPT(OR=2.38,95%CI:1.18-4.78),LPT(OR=1.63,95%CI:1.07-2.48) and ET(OR=1.42,95%CI:1.12-1.81) infants were much higher. Conclusions Moderate,late and early preterm increase the risk of delayed neurodevelopment proportion compared with full term infants. And an inverse dose-response relationship between gestational age and risk of developmental delay is found in the tested children.
