Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The main objective of the 3D study is to create a large pregnancy and birth cohort, allowing for the assessment of the effects of combined prenatal exposure on both birth outcomes and longer-term infant and child health. The specific objectives are to:
1. Determine the effects of pre- and post-natal exposures to environmental contaminants, nutritional factors and psychosocial stress on pregnancy and neurodevelopmental outcomes;
2. Assess the contribution of social, genetic, epigenetic, nutritional and environmental factors to the etiology and outcomes of intrauterine growth restriction (IUGR) and preterm birth; and
3. Assess the effects of assisted reproductive technologies (ART) on indicators of epigenetic modifications, and the relationship between such epigenetic changes and infant neurodevelopmental, cardiovascular, and metabolic outcomes.
