Abstract: Objective To explore the premature effect on the mental,motor and visual cognitive development of preterm infants from 12 to 36 months of age. Method 55 preterm children(including:very preterm children 25 cases,moderately to late preterm children 30 cases)were selected,40 normal full-term children served as a control group.Bayley-Ⅱ Infant Development Scale was used to evaluate children neurodevelopment at 12,18,24 and 36 months,and the results were indicated as mental development index(MDI),psychomotor development index(PDI) and the rate of visual items passed. Results The very preterm group showed the scores of MDI and PDI were significantly lower than the full-term group at 12,18,24 and 36 months of age(P<0.05); The moderately to late preterm children showed the scores of MDI were significantly lower compared with the full-term group at 12 and 24 months of age(P<0.05),while there was no significant difference in the score of PDI between two groups(P>0.05).The rate of visual items passed among the very preterm children,the moderately to late preterm children and the control group was 46.3%,61.5% and 74.4% respectively. Conclusion Premature has the negative influence on the development of children's cognitive,motor and visual cognitive function,especially for very preterm children.The early intervention in preterm children should be implemented to promote their healthy growth as soon as possible.
