International Children’s Accelerometer Database

Project Details


Objective methods, such as accelerometers, have become a preferred option when measuring population levels of physical activity, examining trends in activity patterns and when examining associations between activity and health outcomes in young people. The International Children’s Accelerometry Database (ICAD) project is a consortium including 20 partners which pooled and reduced raw accelerometer data using standardized methods to create comparable outcome variables in 32,000 young people aged 3 to 18 years across studies from Europe, the US, Brazil and Australia [1].

By pooling and reanalysing accelerometer data from different studies the ICAD has the potential to increase statistical power due to a large sample size, create a more heterogeneous and potentially more representative sample and provide a means to study the causes of inter-study variability in physical activity. Key studies to date have explored the metabolic associations with sedentary time in youth [2] and differing activity levels of youth by age, sex, weight status and country [3].

The ICAD project was funded by the National Prevention Research Initiative in the UK and is led by a steering committee including Prof. Ashley Cooper, Dr. Angie Page, and representatives from MRC Epidemiology Unit, Loughborough University and the Norwegian School of Sports Sciences.

The database is managed by the MRC Epidemiology Unit and is publicly available for data requests.
