Early exposure to environmental contaminants, home stimulation, and child cognitive development trajectories
Ines Gonzalez-Casanova, Ph.D.
BACKGROUND: Children of underserved households are less likely to achieve their full developmental potential. SES is associated with both the risk of exposure to environmental contaminants (ECs) and the quality of the home learning environment, which have been shown to impair cognitive development.
GAP: The role of prenatal exposure to environmental contaminants and home stimulation during childhood on cognitive development are not completely understood, particularly within the context of the strong association between SES and development.
HYPOTHESIS: Prenatal exposure to environmental contaminants and home social environment during early childhood are in the pathway of the association between SES and child development
METHODS: This is a longitudinal study of the effect of household socioeconomic status, environmental contaminants, and home environment stimulation on child development across time. The study includes 802 mother-child pairs participating in a trial being conducted in Cuernavaca, Mexico, with available information on household socioeconomic status, environmental contaminants or home stimulation, and at least one measure of cognitive development during childhood.
IMPACT: This research can be translated into recommendations to promote home environments that contribute to an optimal childhood development, especially among those most at risk.
