Executive Function in Children Born Moderate-to-Late Preterm: A Meta-Analysis.

Context: The risk of early neurodevelopmental delay is increasingly recognized in children born moderate-to-late preterm (MLP; 32-36 weeks' gestation), but school-aged cognitive outcomes are unclear, particularly for domains such as executive function (EF).

Objective: To evaluate EF outcomes (attentional control, cognitive flexibility, and goal setting) in school-aged children born MLP compared with children born at term.

Data Sources: Medline, Embase, PsycInfo, and Scopus.

Neurodevelopment at Age 9 Years Among Children Born at 32 to 36 Weeks' Gestation.

Importance: Although children born moderate to late preterm (MLP; 32-36 weeks' gestation) have more neurodevelopmental problems compared with children born early term or later (≥37 weeks' gestation), detailed understanding of affected domains at school age is lacking. Little is known of risk factors for poorer development.

Objective: To examine whether being born MLP compared with being born early term or later is associated with neurodevelopmental outcomes at age 9 years and to describe factors associated with poorer neurodevelopment in children born MLP.
