Team to Address Bariatric Care in Canadian Children
(Team ABC3): Aim2Be Randomized Controlled Trial


In 2013, the Canadian Institutes of Health Research (CIHR) launched a strategic research initiative aimed at providing evidence regarding severe obesity and its treatment. Following an extensive CIHR peer review process, Team to Address Bariatric Care in Canadian Children (Team ABC3) was one of the three successful candidates. 

Team ABC3 is a large, coordinated group of researchers and clinicians from across Canada that received funding from CIHR to launch seven projects in Vancouver, Edmonton, Toronto and Hamilton over five years. Collectively, the team’s research focuses on understanding and managing obesity in children


One of the seven Team ABC3 projects is evaluating the Aim2Be app. The project is based out of Vancouver and is led by Dr. Louise Mâsse of the University of British Columbia. 

The Aim2Be app is being designed to support Canadian youth (10-17 years) and their families in adopting lifelong healthy behaviours in four areas: healthy eating, physical activity, recreational screen time, and sleep. The app content blends best evidence with behaviour change techniques to provide a non-judgemental, tailored and family-focused approach to support youth and their families to reach current Canadian lifestyle recommendations.


We are recruiting youth (10-17) and their parents (one parent and one child per family) to use Aim2Be over 6 months and provide feedback via online questionnaires. We will mail you a scale, measuring tape, and Fitbit that will be yours to keep. Three times during the study, teens will be asked to wear the Fitbit for fourteen days, and a parent will be asked to report their child’s height and weight. Participating families will receive up to $240, based on the number of study activities they complete. In order to participate, parent and teens must meet the following criteria:  

  • Teen must be between 10 and 17 years old
  • Teen must have a body mass index (BMI) above the 85th percentile for their age
  • Parent and teen must be literate in English and be able to read at the grade 5 level or above
  • Parent and teen must have a computer or mobile device, and internet access at home
  • Teen must primarily live in the household with the participating parent

Our staff will follow up with you in a few days to complete a screening questionnaire, and to determine your eligibility to enter the study.
