Accelerometry data reduction settings for ICAD 2 (Dec 2015):.Video of ICAD symposium at ISBNPA Annual Meeting (June 2015, Edinburgh).Dec 2018: Day-time only summary variables (Evenson cut-points) now available.ICAD approved proposals and progress (updated Mar 2021).Acknowledgement slide for presentations (with new logo).MRC Epidemiology Unit data sharing pages.We are processing ICAD applications, but please be aware that the process may take slightly longer. PLEASE NOTE: All ICAD and MRC Epidemiology Unit staff are working from home during the COVID-19 pandemic. Data will be released in chronological order by date of proposal acceptance and is usually within 5 to 10 working days. Please contact with data requests using the application form below. General and pre-submission enquiries should be directed to Lauren Sherar ( Please review the available variables, and the information provided on data harmonisation.
Please find information regarding the application process to access the data below. The ICAD is open for data requests as a supported access resource. For the purposes of ICAD data sharing the following definition of a bona fide researcher has been adopted (see p24). The database is managed by the MRC Epidemiology Unit and is publicly available for data requests from bona fide researchers across the world. The ICAD Working Group consists of: Dr Andrew Atkin, Prof Ulf Ekelund, Dr Dale Esliger, Dr Bjorge H Hansen, Dr Lauren Sherar, and Dr Esther van Sluijs. A Working Group manages the day-to-day running of ICAD. The ICAD is managed in collaboration by the MRC Epidemiology Unit, Loughborough University, Norwegian School of Sport Sciences, University of Agder (Norway), and University of East Anglia. ICAD is led by a Steering Committee including representatives from all contributing partners. The initial ICAD project was funded by the National Prevention Research Initiative.
Example harmonised variables have been derived for a range of demographic and health-related constructs further data is available for harmonisation by individual researchers (see Data Harmonisation page). All accelerometer data has been reprocessed to ensure consistency across waves. Compared to the first release, the updated ICAD includes more longitudinal data and provides access to a wider range of non-accelerometer data.
increase statistical power due to a large sample size.In addition, non-accelerometer data were harmonised in a transparent and structured way.īy pooling data from different studies the ICAD has the potential to: Data were processed to create comparable accelerometer variables in over 37,000 young people aged 3 to 18 years across studies from Europe, the US, Brazil and Australia. The International Children’s Accelerometry Database (ICAD) project is a consortium including 20 partners which pooled and reduced raw accelerometer data using standardized methods. 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.
