Update on the Covid-19 situation

We at MIREC are closely monitoring the COVID-19 situation. These are challenging times for everyone. The in-person components of our ongoing MIREC-ENDO follow-up study have been paused. Meanwhile, we have resumed remote data collection activities, with an eye to ensuring that we do not lose touch with our participants, or miss important milestones in children’s development. We will keep our participants informed about any further changes to study activities as the situation evolves.

To the MIREC participants:
At this time, we are not able to invite you to our clinic for MIREC-ENDO visits. Phone calls, emails, and other remote data collection activities may continue.

For any questions related to your participation in MIREC studies, you can reach us by clicking on “Contact Us” at the top of this page.

What is MIREC?

The Maternal-Infant Research on Environmental Chemicals (MIREC) Study started back in 2007. Our goal was to examine the effects of prenatal exposure to environmental chemicals on the health of pregnant women and their infants.

From 2008 to 2011, we recruited 2001 pregnant women from 10 Canadian cities. We followed them at each trimester and at birth, collecting a wealth of data from questionnaires and physical measurements (e.g., blood pressure, weight). We also collected biological specimens from the mother (blood, urine, hair, milk) and the infant at birth (cord blood, meconium).

Since 2011, we have completed three follow-up studies (MIREC-ID, MIREC-CD3, and MIREC-CD Plus), and have begun a fourth one called MIREC-ENDO. ENDO stands for endocrine, named for the endocrine system which secretes hormones into the bloodstream to regulate body functions. In 2018, we have begun enrolling families in the first phase of the study, and we will continue to do so until March 2021.

MIREC also includes a data and biospecimens Biobank, for future research. We refer to this body of research as the MIREC Research Platform.
