摘要
Background and aims: Although the intelligence quotient (IQ) test is useful to assess general cognitive function, it may miss more specific and subtle deficits of learning, working memory, attention and executive function. This study aims to evaluate cognitive performance and academic school readiness (SR) concepts in preterm very low birth weight (PT/VLBW) children, compared to typically developing term controls and to evaluate factors affecting basic (SR) concepts in children with IQ>85. Methods: A prospective cohort study of 123 PT/VLBW survivors with birth weights ?1250 g and 74 term controls born between 2007 and 2009 in Singapore were assessed for school readiness using Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III), Bracken School Readiness Assessment (BSRA-3) and Beery-Buktenica Developmental Test of Visual Motor Integration (VMI) at age 5.5 years. Social risk composite score (SRCS) was calculated based on ethnicity, parental education and family income and marital status. Uni- and multi-variable regressions were conducted to evaluate risk factors associated with poor academic SR in the entire cohort and in those with IQ >85. Results: Mean gestational age and birth weight of the 123 PT/VLBW children were 27.8 (2.3) weeks and 939 (194) grams while that of the 74 term controls were 38.8 (1.2) weeks and 3165 (402) grams. PT/VLBW survivors had statistically significant lower full composite scores on WPPSI-III (97.0 vs 114), BSRA-3 (98.5 vs 112.3) and VMI (107.2 vs 112.9) compared to controls. The differences remained significant in preterm and children with higher SRCS even after adjustment. Conclusions: Prematurity and high social composite risk scores were risk factors affecting academic SR and this difference persisted in PT/VLBW children with normal cognitive scores with IQ >85.
