Montreal Antenatal Well-Being Study

Lead Researcher: Kieran O'Donnell, PhD




As many as one in five moms experience anxiety or depression during pregnancy, the experience of which is associated with detrimental outcomes for both mothers and their children. For example, maternal suicide is a leading cause of death in the prenatal period. Likewise, research shows that a mother's prenatal mental health can affect her child's development, including cognitive and socio-emotional development. Little is understood about how biological, social and psychological factors combine to increase women's risk of experiencing adverse mental health during pregnancy. Neither do we understand why some children experience the developmental affects of prenatal mental health while others do not. 

The Montreal Antenatal Well-Being Study is one of the largest studies in Canada to better understand how biological, social and psychological factors combine to influence women’s mental health and well-being  during pregnancy and the postpartum period. We are also seeking to understand when the best time is to screen pregnant women for anxiety and depression. We hope that, in the future, this will allow us to better support women who need help to boost their mood during pregnancy.
