Título: Efecto del sexo, peso y gravedad de la prematuridad en el neurocomportamiento de recién nacidos prematuros a través de la Neonatal Behavioral Assessment Scale. Resumen: El aumento de los recién nacidos prematuros en los últimos años hace que se incremente el interés por estudiar las consecuencias de este factor de riesgo. En este trabajo se evalúan 30 prematuros (a las 40 semanas de edad gestacional) con la Escala para la Evaluación del Comportamiento Neonatal de Brazelton y se comparan sus resultados con los de un grupo control formado por 28 neonatos a término. Así mismo se comparan dentro del grupo de prematuros el efecto del peso, el sexo y la gravedad de la prematuridad. Los controles muestran superioridad en 9 de los 28 ítems comportamentales de la Escala y en dos de las 5 categorías. Los prematuros muestran superioridad en Habituación. Las niñas muestran mejor ejecución en la categoría Social-Interactiva. Los prematuros se ven afectados por la abrupta interrupción de su maduración intrauterina. Aunque podría haber un efecto de aprendizaje debido a la exposición extrauterina.

Abstract:The increasing number of preterm babies in recent years has raised interest in studying the consequences of prematurity as a risk factor. In the present paper, 30 preterm babies (at 40 weeks of gestational age) were assessed using the Neonatal Behavioral Assessment Scale and the results were compared with those of a control group of 28 full term babies. Moreover, the influence of weight, sex and gestational age was analyzed considering the Brazelton results in the preterm group. The preterm group showed significantly lower scores than the control group for 9 of the 28 behavioral items in the Scale and for 2 of the 5 clusters. However, preterm babies performed better in habituation to disturbing stimuli (light and noise) during sleep. In relation to the influence of sex, premature girls performed better in the Social-Interactive cluster. The preterm group has lower neurobehavioral conditions than the full term group, probably due to the abrupt interruption of their intrauterine maturation. In contrast, they showed a better ability of habituation, maybe as a consequence of a learning effect due to earlier additional extrauterine exposition.
