The Infant Development and Environment Study (TIDES)

The Infant Development and Environment Study (TIDES) is a multi-center study designed to examine how everyday chemicals in food, cosmetics, and household products may affect children’s health and development. TIDES researchers are particularly interested in how the mother’s exposure to these chemicals while pregnant may affect children before they are born with changes observable during childhood and later.

Initial Results

The first five years of our study, in which we enrolled almost 800 moms and their babies, has led to a number of important results. Our work suggests that prenatal exposure to common chemicals in our diet and homes –phthalates, which make plastics soft and flexible—may affect the reproductive tract development of boys but not that of girls. These results were affected by the number of stressful life events that the mom reported during pregnancy. We also found that women’s attitudes about phthalates and other environmental chemicals vary widely and can influence their consumer choices and the amount of these chemicals to which they are exposed. View our publications

Further Research-TIDES II

The National Institutes of Health has funded us to follow TIDES children to examine how early exposures shape development in their preschool years.

Study Centers

The Icahn School of Medicine at Mount Sinai is the Data Coordinating Center for TIDES and serves as a participating center along with, the University of Rochester School of Medicine and Dentistry; Seattle Children’s Hospital/University of Washington School of Medicine; University of Minnesota; and University of California at San Francisco.

TIDES is supported by a grant from the National Institutes of Health (NIH / NIEHS) R01 ES25169-1 and the Mount Sinai Translational Center on Early Environmental Exposures (P30) P30ES023515.
