Associations between fertility problems and pregnancy and birth outcomes.


Certain known risk factors influence fertility, including poor diet, polycystic ovary syndrome, increasing maternal age, and increasing BMI. Such factors are also known to be associated with a range of pregnancy complications including gestational diabetes, preeclampsia, and the delivery of an earlier or heavier baby. There are increased risks of obstetric and/or neonatal complications in infertile patients, thus, potentially shared and underlying risk factors that contribute to infertility may also contribute to pregnancy complications and long-term health outcomes of the mother and child. The proposed study will investigate relationships between infertility problems and a range of pregnancy outcomes, taking into account key risk factors for infertility and pregnancy outcomes, such as BMI, diet quality, smoking, and physical activity.
