ObjectiveData on the neurodevelopmental and associated behavioral effects of light to moderate in utero alcohol exposure are limited. This retrospective investigation tested for associations between reported maternal prenatal alcohol use and psychological, behavioral, and neurodevelopmental outcomes in substance-naive youths.MethodsParticipants were 9,719 youths (ages 9.0 to 10.9 years) from the Adolescent Brain Cognitive Development Study. Based on parental reports, 2,518 (25.9%) had been exposed to alcohol in utero. Generalized additive mixed models and multilevel cross-sectional and longitudinal mediation models were used to test whether prenatal alcohol exposure was associated with psychological, behavioral, and cognitive outcomes, and whether differences in brain structure and resting-state functional connectivity partially explained these associations at baseline and 1-year follow-up, after controlling for possible confounding factors.ResultsPrenatal alcohol exposure of any severity was associated with greater psychopathology, attention deficits, and impulsiveness, with some effects showing a dose-dependent response. Children with prenatal alcohol exposure, compared with those without, displayed greater cerebral and regional volume and greater regional surface area. Resting-state functional connectivity was largely unaltered in children with in utero exposure. Some of the psychological and behavioral outcomes at baseline and at the 1-year follow-up were partially explained by differences in brain structure among youths who had been exposed to alcohol in utero.ConclusionsAny alcohol use during pregnancy is associated with subtle yet significant psychological and behavioral effects in children. Women should continue to be advised to abstain from alcohol consumption from conception throughout pregnancy.

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term prospective relations between cognitive control and anxiety. Using longitudinal data from 149 adolescents (55% female; from predominantly White middle-class families), we assessed temperament in toddlerhood and cognitive control and anxiety at 4, 12, 15, and 18 years of age. At age 4, separate measures of task switching and inhibitory control were obtained via the Dimensional Change Card Sort and Stroop tasks, respectively. At 12, 15, and 18 years of age, planful control was assessed with the AX-Continuous Performance Test, and anxiety symptoms were assessed via self-report. Growth curve models revealed that children with greater inhibitory control at age 4, regardless of BI status, experienced a sharper increase in anxiety symptoms across adolescence. Children with heightened BI during early childhood displayed lower levels of planful control at age 12, but experienced a more rapid improvement in these skills across adolescence. Children with greater task switching ability at age 4 displayed higher levels of planful control at age 12, but experienced a smaller increase in these skills across adolescence. Finally, children's growth rate for anxiety was unrelated to their growth rate for planful control. These findings reveal that early-life temperament, cognitive control, and anxiety remain interconnected across development, from toddlerhood to at least late adolescence. Public Significance Statement: This study indicates that temperament and executive function in early childhood predict the future development of anxiety and executive function across adolescence. However, changes in anxiety across adolescence did not relate to changes in executive function across the same period. Together, results suggest that early interventions may have the best chance of improving adolescents' anxiety trajectories. [ABSTRACT FROM AUTHOR]

Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20 years, research has documented within‐child and socio‐contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio‐contextual factors influence differential pathways to anxiety versus resilience.
