The WHO European Childhood Obesity Surveillance Initiative (or COSI), is a unique system that for over 10 years has measured trends in overweight and obesity among primary school aged children. COSI involves taking standardized weight and height measurements from over 300 000 children across the WHO European Region, providing nationally representative data for participating countries, as well as a large Region-wide data set for analysis of the determinants of childhood overweight and obesity

The Department of Nutritional Sciences and Dietetics of the International Hellenic University (IHU) is responsible for COSI Data collection actions in Greece since 2010, when Greece joined the initiative (Round 2). NISLAB is assisting in coordinating the data collection and also developed and maintains the NUTR.IHU questionnaires platform which is used for all online surveys.
