目的:了解影响婴幼儿智能发育因素,及早采取防治措施。方法:用DST法对南阳市3105例入保婴幼儿进行智能发育检查及相关因素调查。结果:智力指数(MI)<85分发生率9.37%,发育商(DQ)<85分发生率15.56%;MI>120分发生率8.21%,DQ>120分发生率8.40%。出生低体重、早产、阳性家族史、母亲低龄生育、出生窒息、胎头吸引器助产,人工喂养及未胎教的婴幼儿发生智能低下的构成比依次明显高于正常儿童,经统计学处理,差异有统计学意义。母乳喂养有利于智能发育。结论:出生前、出生时、出生后的不良因素对婴幼儿的智能发育有重要影响。
Objective: To understand the factors that affect the intelligence and development of infants and young children, to take early prevention and treatment measures. Methods: DST was used to investigate the intelligence development of 3105 infants in Nanyang City and related factors. Results: The incidence of MI <85 was 9.37%, the incidence of DQ <85 was 15.56%, the incidence of MI> 120 was 8.21%, and the incidence of DQ> 120 was 8.40%. The proportions of low birth weight, premature birth, positive family history, low mother birth, birth asphyxia, fetal head suction midwifery, artificial feeding and non-prenatal infant mental retardation were significantly higher than normal children, the statistics, The difference was statistically significant. Breastfeeding is good for smart development. Conclusions: Prenatal, birth, and postnatal adverse factors have a significant impact on the infant’s intellectual development.
