The Triple B Study: Bumps, Babies and Beyond is an innovative Australian study of approximately 1,600 families. The project is a longitudinal pregnancy cohort which examines a range of biopsychosocial factors that relate to the health and development of Australian children and families. Importantly, the project has a key focus on examining the impacts of substance use and mental health in pregnant women and their partners during the prenatal period on child development and family functioning. The results of this study will inform public health and treatment initiatives that improve the health and wellbeing of Australian children and families.
