Cognitive performance at school age of very low birth weight infants with bronchopulmonary dysplasia.

Full Abstract

The hypothesis was that bronchopulmonary dysplasia (BPD) adversely affects cognitive performance at school age. This prospective cohort study examined three groups of children at 8 to 10 years of age. Group 1 (n = 311) consisted of very low birth weight (VLBW) infants without BPD and Group 2 (n = 95) consisted of VLBW infants with BPD. Group 3 (n = 188) consisted of term infants without BPD. Regression analysis determined the effect of BPD on eight performance measures while controlling for possible confounding variables. Children in Group 3 had the best performance and children in Group 2 had the poorest performance on all measures. These differences were significant (p = .0001) for the Full Scale IQ, Performance IQ, and reading and math grades and ages. Children in Groups 3 and 1 performed better than children in Group 2 for the Verbal IQ (p = .0001) and the Developmental Test of Visual-Motor Integration (p = .0012), but for these two measures there was no significant difference between children in Groups 3 and 1. Thus, poorer performance was found in VLBW infants with a history of BPD.
