小于胎龄儿智力发育的研究进展

摘要

Small for gestational age (SGA) infants are defined as infant with a birth weight below the 10th percentile of the average weight for gestational age or below 2 standard deviations for gestational age.More evidences have suggested that compared with the appropriate for gestational age infants,besides the short stature,there are also higher risks of lower intelligence,poor academic performance,low social competence,behavioral problems in SGA infants.%小于胎龄儿是指出生体重在同胎龄儿平均体重的第10百分位以下或低于平均体重2个标准差的新生儿.近年来,越来越多的证据表明小于胎龄儿除了存在身材矮小的问题,与适于胎龄儿相比,小于胎龄儿更有可能息有低智商、学业不良、社会适应性差及行为问题等.
