KEP: Reproductive Epidemiology
“The time we spend in utero is undoubtedly the most important developmental time period of our lives; we go from one cell to a viable individual in roughly 38 weeks!”
Sara Öberg, PhD thesis, Karolinska Institutet, 2011
Our aims are to understand the etiology and factors influencing:
- risks of maternal and fetal/infant health during pregnancy, delivery and after delivery;
- associations between pregnancy and the long term prognosis for the mother and child.
For this purpose, we use population-based research registries and local data bases. The research is performed in collaboration with other research groups within the Clinical Epidemiology Unit (KEP), other research groups within Karolinska Institutet and other universities in Sweden and internationally.
Maternal overweight and obesity and risk of preterm delivery
Using the Swedish Medical Birth Register, we found that risk of preterm delivery increased with maternal BMI. Maternal overweight increased risks of both spontaneous and medically indicated extremely (<22-27 weeks) preterm delivery, while associations with very and moderately preterm delivery (28-31 and 32-36 weks, respectively) were mainly confined to medically indicated preterm delivery.
