RESUMEN
Objective To provide scientific evidences for improving children early integrated development,through analyzing the mental developmental status and characteristics of 322 cases of 2-year-old children in Nanjing.Methods Intelligence and motor development condition in 322 cases of 2-year-old children were assessed by using Bayley Scales of Infant Development test,and the assessed results were analyzed.Results 1.The incidences of the children whose mental development index(MDI)or psychomotor development index(PDI)were under 69 were 3.1% and 5.6%,respectively;2.The MDI mean score(114.34?19.65)was significantly higher than that of PDI(101.73?21.53)(t=9.71,P0.05).Conclusions The incidences of mental retardation in this study were consistent with the result reported by World Health Organization.There were differences between motor and intelligence development in children,as well as the intelligence development between male and female.Therefore,it should be implemented early childhood developmental screening in child health care.Parents should be given scientific guides about intelligence and motor development of children.
