In 2009, we received funding from Health Canada for a follow-up study called MIREC-ID (standing for Infant Development), to follow MIREC mothers and infants at birth and 6 months of age. In total, MIREC-ID enrolled 525 MIREC mothers from our Vancouver, Hamilton, Kingston, Ottawa, Montreal and Halifax sites.
The purpose of this follow-up was to evaluate whether prenatal exposure to environmental chemicals had any measurable effect on the infant’s growth, general development and behaviour at 6 months.
We finished the last 6-month assessment in March 2012. The analyses for this study are also underway. As for MIREC, we will share with you all the findings and publications when available.
With the completion of the MIREC and MIREC-ID studies, a new follow-up study started in 2012. This study, also funded by Health Canada, is called MIREC-CD3, standing for Child Development at age 3.
This new follow-up study was focusing on mothers and their MIREC toddler at age 3. The goal of this study was to collect data that will help us learn more about the potential links between prenatal exposures, language and behaviour.
In 2013, we were happy to launch a new follow-up of our MIREC children called MIREC-CD Plus, standing for Child Development, but not limited to age 3.
We invited the MIREC families from our Vancouver, Toronto, Hamilton, Kingston, Montreal and Halifax site to participate in that follow-up, which included a biomonitoring and a neurodevelopmental component. The visits were made mainly in the participants’ homes.
The main objective was to assess exposure of the MIREC child to environmental chemicals and measure his/her growth, development and behaviour.
In 2018, we started MIREC-ENDO, a new follow-up study of our MIREC children.
ENDO stands for endocrine, the system secreting hormones into the bloodstream to regulate the body.
We will be looking at prenatal exposure to environmental chemicals and their effect on growth, behaviour, language development and the general development of the MIREC children. We have begun enrolling families, starting with the oldest children, and we will continue to do so until March 2021.
