About our research group/lab
Interactions between parental conditions, environmental exposures, and genetic variations affect growth, development, plasticity, and functioning of parental gametes and (extra-) embryonic and fetal organs. Evidence is compelling that these interactions during pregnancy also contribute to obesity and other non-communicable diseases during the life course. Most reproductive failures, pregnancy complications, and adverse pregnancy outcomes originate in the periconceptional period, a time window of 14 weeks before and up to 10 weeks after conception. Therefore, we focus our research on this specific window to achieve the greatest short- and long term health benefits for both the mother, father and their (unborn) child.
The research group Periconception Epidemiology investigates the influences of the maternal and paternal 1-carbon metabolism, cardiovascular and metabolic pathway and lifestyle behaviours (folic acid, nutrition, smoking, alcohol, exercise) on parental health, and embryonic and fetal development and growth, in the periconceptional period. With these findings, we developed innovative eHealth and digital interventions, such as Slimmer Zwanger (Smarterpregnancy), targeted at improving poor lifestyle factors. Slimmer Zwanger is a proven (cost-)effective interactive tailored coaching platform, which not only increases healthy behavior of participants, but also increases chances of ongoing pregnancy.
Rotterdam periconception cohort (Predict study)
A major part of our research is embedded in the Predict study, a large ongoing prospective cohort study focused on women and partner enrolled in the periconception period. This study started as a pilot and since 2010 consist of > 3000 couples and pregnancies. Here, we focus on the investigation of:
determinants of the couple’s periconceptional health;
the reproductive performance and pregnancy course and outcome;
the underlying epigenetic profiles to explain associations between periconceptional parental health, reproductive performance and pregnancy course and outcome.
Thus far, we have welcomed numerous scientists and students from various scientific disciplines (medicine, nutrition, biomedical sciences, epidemiology, psychology, technology, industrial design) and from all over the world. Thus far, 45 PhD students have finalized their PhD in our group and more than 200 MSc or MD projects have been completed within the team.
