This article presents a revision of the literature regarding the influence of sex differences on the recovery and long-term behavioral and cognitive outcomes of preterm children. After initial discussion of some methodological concerns, the literature regarding the concept of "male disadvantage," which is often used when talking about early neurological and psychomotor outcomes in preterm children, is presented. Subsequently, the literature data on sex-related differences in preterm children are discussed, focusing on their influence on the developmental pathways of cognition, language, executive function, behavior and affect, and response to rehabilitation therapies. Finally, evidence about brain structural and connectivity correlates of sex differences in the brain of preterm survivors is taken into account. Although visuo-spatial and visuo-perceptual functioning is widely studied in the preterm child and is strongly sex specific, little to no data are available regarding male-female differences in preterm children and the interaction effect between sex and preterm birth. For this reason, original data analyses of male-female differences in visuo-spatial performance from a small sample of preterm children are also presented.
Keywords: neurocognitive outcome; prematurity; sex differences; visuo-spatial.
