“…These measures suggest that prematures as a group have not caught up at the ages of eight to ten years to the extent that low birth weight children are relatively impaired on both tests. 1 This analysis controlled for three levels of social class as determined by an index consisting of parental education, income, housing and employment. F ratios for the interaction of three levels of social class with four levels of birth weight were 1.34 and 0.60 (6 and 810 df) for the Stanford-Binet test and WISC respectively.…”

An earlier report considered the mental status of these subjects when they were six to seven years of age [6].…”

ExtractFive hundred low birth weight children and 492 full-term infants were seen when approximately 40 weeks of age for a pediatric-neurologic examination. Of these, 822 provided the data upon which this report is based. To each child, when eight to ten years of age, there was administered ten subtests of the Wechsler Intelligence Test for Children (WISG), the Bender Gestalt Test and the Wide Range Reading and Spelling Achievement Test. In addition, observations were recorded regarding speech articulation and complexity of grammar. The number of perseveration instances and indications of possible comprehension aphasia observed during the examinations were recorded. The Verbal IQ_, Performance IO_ and Full Scale IO_ scores, as well as the independently obtained Bender Gestalt score, showed increasing impairment with decreasing birth weight. Approximately twice as large a proportion of low birth weight children as of control children fell into the IO_ category (50-79) which is associated with special medical or educational needs. At the ages of six to seven years the results of the Stanford-Binet Test showed an IQ, difference between the low birth weight and full-sized groups of 3.4 points (F = 7.77, 3 and 810 df, p < 0.001), whereas the WISG given at the ages of eight to ten years indicated an IO_ difference of 4.9 points (F = 10.87, 3 and 810 df, p < 0.001) for the same samples of children. Of the twenty psychological measures used to assess development of those who had been premature, relative impairment on 16 were significantly associated with birth weight and one was nearly so at the 0.05 level of significance. When the effect of the presence of indicators of possible neurologic abnormality was removed by analysis of covariance, the statistical significance of the association with birth weight was reduced for each of the variables measured, and only six of the twenty remained with significant assocation. SpeculationFuture research might profitably consider whether performance by adolescents of low birth weight is relatively impaired in scholastic situations. Also, recent research suggests that a low birth weight occurring in conjunction with long gestational periods, may significantly prejudice intellectual capacity. However, there are little longitudinal data regarding this.

“…The connection between prematurity and intelligence defects has been analyzed by a long series of authors, using both the retrospective and prospective method of study. Rosanoff and InmanKane showed as early as 1934 that the mentally defective were more often born prematurely than others, and this was later confirmed by Beskow (1949), Blegen (1952), Harper et al (1959), Drillen (1961 and, and others. Douglas (1960) and Baird (1962) believed that the low intelligence frequently associated with prematurity was not due to the prematurity but to social factors correlated with prematurity.…”

where and transferred to the Premature Infant Center. During this time, a total of 187 infants were admitted of whom 87 died in the neonatal period while 6 succumbed in the subsequent 11 months. The 94 who survived the first year of life constituted the sample to be followed.The examination included medical and neurologi¬ cal examinations, psychological testing, electroencephalography, ophthalmological examination, and evaluation of the social situation of the families of the patients. The children returned to the Out Pa¬ tient Department of the Colorado General Hospital for these examinations.
