Maternal-Infant Research on Environmental Chemicals (MIREC)
The MIREC Study examines the effects of prenatal exposure to environmental chemicals on the health of pregnant women and their infants. From 2008 to 2011, the study recruited approximately 2,000 participants in their first trimester of pregnancy from 10 cities across Canada. The cohort were followed at each trimester, at birth and up to 2 months after delivery, and contributed data through questionnaires, biospecimens and physical measurements. Since the original MIREC Study, multiple follow-up studies of the MIREC children and mothers have been conducted.
