The All Our Families cohort: understanding development across the lifecourse by Mary Canning

SAGE and All Our Families (AOF) are excited to announce that new data from the AOF study is now available through SAGE, just in time for our SAGE Secondary Data Use Grant. Researchers can now apply to use the AOF 36-month data via SAGE – find out more below!


The All Our Families (AOF) study is a Canadian longitudinal cohort study, following mother-child pairs from 25 weeks gestation to present, wherein the first wave of recruits have children turning 8 years of age in 2017. The self-reported data collected has given us tremendous insight to families in a typical urban setting, including information on breastfeeding, maternal mental health, lifestyle, language development, screen time, sleep and nutritional habits, and many more aspects of family life.

Through SAGE, anonymized AOF data is available to investigators, trainees and students who meet data access criteria (e.g. sound scientific question, Research Ethics Board approval). Examples of previous studies utilizing AOF data include topics such as Vaccine Hesitancy in Canadian Parents, Prenatal Counselling and Gestational Weight Guidelines, Risk Factors of Antenatal Anxiety, Risk and Resilience Factors Influencing Child development , Factors influencing Postpartum Depression, and Late Talking Toddlers: Patterns in Vocabulary Development, to name only a very few.

Recently, the SAGE repository added the 36-month time frame data to the AOF deposit. It now includes data from 6 collection points, starting at less than 25 weeks gestation and up to 36 months of age. The participants’ postal codes have been linked to the 2011 NHS Census data to reflect neighbourhood characteristics. Other data includes information collected from participants following the 2013 Calgary Flood, as well health information from birth records.
