          Abstract

          Cada vez nacen más gemelos con discordancia de peso intrapar, factor de riesgo que puede afectar su desarrollo, especialmente el del hermano de menor peso intrapar. Sin embargo, pocos estudios abordan sus posibles disfunciones más allá de las obstétricas; de modo que el conocimiento acerca de las consecuencias de la discordancia de peso intrapar en su desarrollo psicológico es escaso. Este trabajo revisa la literatura y recapitula las consecuencias de la discordancia de peso intrapar en el desarrollo psicológico de los gemelos de menor peso intrapar, comparativamente a sus hermanos de más peso, así como la perdurabilidad de dichas consecuencias durante su ciclo vital. La literatura revisada muestra que los gemelos de menor peso intrapar obtienen puntuaciones inferiores a sus hermanos en habilidades cognitivas, verbales y psicomotoras; y mayor probabilidad de presentar rasgos asociados al desarrollo de hiperactividad. Estas diferencias persisten desde la infancia hasta la juventud, no existiendo datos referidos a la edad adulta. En conclusión, las consecuencias de la discordancia de peso intrapar sobre el desarrollo psicológico de los gemelos de menor peso intrapar son extensas tanto en las dimensiones afectadas como en su perdurabilidad. Es necesaria una mayor investigación que permita diseñar intervenciones tempranas preventivas y optimizadoras del desarrollo de estos niños; pues el óptimo desarrollo de todos los niños es la base de una sociedad en continuo progreso.

          Translated abstract

          More twins are being born with intrapair birth weight discordances. Discordance in birth weight is a risk factor that can affect the development of twins, especially that of the lightest twin. However, few studies have analysed the possible consequences of birth weight discordance on the lightest twin beyond possible neonatal obstetric problems. Thus, little is known about the consequences of birth weight discordance on the psychological development of such babies. This article reviews the literature and summarizes the effects of birth weight discordance on the psychological development of the lightest intrapair twins compared with their heavier twin siblings and the persistence of these effects during their lifetime. The literature shows that the lightest intrapair twins obtain lower scores than their siblings in cognitive, verbal, and psychomotor skills. They are also more likely to have traits associated with the development of hyperactivity. These differences persist from childhood to youth. There is no information about adulthood. In conclusion, birth weight discordance has marked effects on the psychological development of intrapair lower weight twins, both in relation to the affected dimensions and the persistence of these effects over time. Further research is needed on designing early preventative interventions that would optimize the development of these children. This proposal is of relevance, given that the optimal development of all children is the basis of a society in continuous progress.

            Socioeconomic status and executive function: developmental trajectories and mediation.

            Childhood socioeconomic status (SES) predicts executive function (EF), but fundamental aspects of this relation remain unknown: the developmental course of the SES disparity, its continued sensitivity to SES changes during that course, and the features of childhood experience responsible for the SES-EF relation. Regarding course, early disparities would be expected to grow during development if caused by accumulating stressors at a given constant level of SES. Alternatively, they would narrow if schooling partly compensates for the effects of earlier deprivation, allowing lower-SES children to 'catch up'. The potential for later childhood SES change to affect EF is also unknown. Regarding mediating factors, previous analyses produced mixed answers, possibly due to correlation amongst candidate mediators. We address these issues with measures of SES, working memory and planning, along with multiple candidate mediators, from the NICHD Study of Early Childcare (n = 1009). Early family income-to-needs and maternal education predicted planning by first grade, and income-to-needs predicted working memory performance at 54 months. Effects of early SES remained consistent through middle childhood, indicating that the relation between early indicators of SES and EF emerges in childhood and persists without narrowing or widening across early and middle childhood. Changes in family income-to-needs were associated with significant changes in planning and trend-level changes in working memory. Mediation analyses supported the role of early childhood home characteristics in explaining the association between SES and EF, while early childhood maternal sensitivity was specifically implicated in the association between maternal education and planning. Early emerging and persistent SES-related differences in EF, partially explained by characteristics of the home and family environment, are thus a potential source of socioeconomic disparities in achievement and health across development.
