VANCOUVER, B.C. -- Late preterm infants have a higher incidence of future neurodevelopmental two studies showed.

In the one study, a team from the University of Iowa in Iowa City performed structural brain MRIs on 52 children an average of 9.4 years old who were born at 34-36 weeks, and 74 children with a mean age of 10 years born at term. All of the children were singletons.

Among other findings, the mean volume of subcortical tissue was almost a quarter standard deviation lower in late preterm (LPT) children than in children born at term, a difference driven mostly by smaller thalami and hippocampi.

"The structural difference on MRI directly related to areas in which the LPT cohort performed more poorly" on a battery of assessments, especially visual short-term memory (Pearson coefficient [r] = 0. …
