Abstract
Objective To investigate the neurobehavioral developmental differences between late-preterm infants and full-term infants at 12 months and 18 months of age, and to compare the neurobehavioral developmental changes at these two periods.Methods In the study 75 late-preterm infants and 80 full-term infants were selected as samples to test and compare their neurobehavioral development at 12 months and 18 months of age.Results At the age of 12 months, late-preterm infants had significantly lower quotient scores in the aspects of big movement, fine motor, adaptibility, language and personal social intercourse than the full-term infants ( t value was -3.837, -5.801,-3.532, -5.258 and -4.582, respectively, all P<0.05).At the age of 18 months, late-preterm infants still had significantly lower quotient scores in the above five aspects (t value was -2.786, -3.967, -4.946, -4.155 and -3.449, respectively, all P<0.05). Late-preterm infants’ score of big movement was obviously higher and that of personal social intercourse was remarkably lower at the age of 18 months than at the age of 12 months (t value was 1.982 and -4.214, respectively, both P<0.05).For the full-term infants the scores of big movement and adaptability were significantly higher and the score of personal social intercourse was lower at the age of 18 months (t value was 2.188, 2.683 and -3.880, respectively, all P <0.05).Conclusion Late-preterm infants’ neurobehavioral developmental level is lower than the full-term infants’ both at the age of 12 months and 18 months.Both late-preterm infants and full-term infants have lower scores of personal social intercourse at 18 months of age than at 12 months of age, but the reason for it needs to be further explored.Late-preterm infant’ s neurobehavioral development is not mature enough, so it is very important to concern and promote early development of late-preterm infants.关键词
