Abstract

© 2015 Taylor & Francis. Objective: Intrauterine-growth restriction is associated with impaired neurodevelopment. However, studies on early childhood neurodevelopment of premature infants with placenta-related intrauterine-growth restriction (IUGR) are scarce and heterogeneous. We aimed to analyze the impact of placenta-related IUGR on preschool age neurodevelopment in preterm infants, and to ascertain which prenatal and postnatal factors influence neurodevelopment in these infants.Methods: Prospective cohorts study: 48 placenta-related IUGR premature infants and 25 matched non-IUGR premature infants (mean gestational age: 31.4 and 31.6 weeks, respectively). Preschool neurodevelopment assessment with cognitive Bayley Scales III and with ASQ-III surveys (age interval: 34.07-42.50 months). Inter-cohort result comparison. Analysis of perinatal and environmental factors associated with impaired neurodevelopment in both cohorts.Results: No statistically significant neurodevelopment differences were observed at preschool age between both preterm cohorts. Multivariate analysis of perinatal and environmental factors showed daycare, breastfeeding, higher parental educational level, and absence of severe neonatal morbidity to be associated with a lower risk of altered neurodevelopment at preschool age.Conclusions: Placenta-related IUGR does not have a significant impact on preschool neurodevelopment in our preterm patients. Instead, post-natal positive environmental factors such as parental educational level, breastfeeding, and daycare attendance make a difference towards an improvement in neurodevelopment in these infants.
