Study Overview

All Our Families is a longitudinal cohort study about pregnancy, parenting and child development.


All Our Families includes over 3,200 women recruited during pregnancy, some of whom participated in a group prenatal care program (Centering Pregnancy), and some provided blood samples and cord blood. All Our Families mothers have described their experiences and lifestyles during pregnancy, as new parents, as parents of toddlers, preschoolers, and as the All Our Families children engage in formal schooling.

Participating families have completed routine questionnaires at time points relevant for understanding child development and family well being, and they also participate in important topical questionnaires when major events happen such as the H1N1 outbreak (2009), the Calgary Flood (2013), and the COVID-19 Pandemic (2020-2023). Some of our research has involved in-person assessments of children, where families have contributed further by coming to our research centre to meet with researchers and engage in developmental assessments.
