RESUMO
Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.
