While the MIREC researchers and student trainees continue analysing the data collected so far, we are searching for funding to conduct additional research. We hope that we will be able to continue to follow the MIREC children as they get older. The focus will now shift towards puberty—when it starts and how it progresses. Visit us often, we will keep you informed!

The MIREC Research Platform is an important resource for research on the mother’s and child’s health. The usefulness of the material collected goes far beyond this single study. The unused portions of the biological samples collected were saved to create what became the MIREC Biobank, which also includes a very large dataset from questionnaires and laboratory analyses. Since the initial study, which followed 2001 pregnant women, three follow-up studies were conducted, and five projects were done, based on the Biobank content. For more information regarding the MIREC Biobank, please refer to the below documentation. Do not hesitate to contact us if you have questions.
