Environmental Risk Exposure and its Effects from Infancy to Adolescence: Differential Susceptibility to Context

Wed, April 7, 11:35am to 1:05pm EDT (11:35am to 1:05pm EDT), Virtual

Session Type: Paper Symposium

Abstract

The symposium brings together cutting-edge research to explore contextual risk factors to inform our understanding of how to enhance children and youth’s well-being. Presentations will focus on contextual (i.e., maternal and neighborhood) exposures from the prenatal period to adolescence, examining how early environmental risk may impact later child development. The first presentation uses two studies to examine how prenatal inflammation impacts cognitive development during childhood. Findings demonstrated that prenatal infection and inflammation was associated with more communication disorder and hyperactivity symptoms during childhood (i.e., 8 years) as well as lower Bayley scores at 12 months. The second presentation explores how environmental toxins, air pollution, during the prenatal period impact inhibitory control during childhood and academic achievement during early adolescence. Results showed a mediation process such that that the impact of higher air pollution exposure on lower academic performance was explained by inhibitory control in girls only. The last presentation examines how the timing of residential moves during childhood and adolescence impacts internalizing and externalizing behaviors as well as academic achievement. Contrary to expectations, findings demonstrated that moving during childhood and adolescence was positively associated with academic performance. However, during adolescence, moving was also associated with more internalizing symptoms. Together these studies continue to advance developmental science using interdisciplinary scholarship and diverse samples to show differential susceptibility to and implications of environmental risk. The discussant will highlight the implications of the ECHO (Environmental Influences on Child Health Outcomes) program’s collective work and provide recommendations for future studies to address lingering questions.
