In order to contribute to the goals of the EU Action Planon Childhood Obesity 2014-2020, a Joint Action on Nutrition and Physical Activity (JANPA), co-funded by Member States and the 3rd EU Health Programme, was launched in 2015. JANPA fosters the discussion and sharing good practices among 25 Member States and Norway using four technical work packages (WP). As outcomes, JANPA promotes 1) advocacy based on an estimation and forecast of economic cost of childhood overweight and obesity (WP4); 2) increasing use of nutritional information on food and diet by public health authorities, stakeholders and families as well as for nutrition policy purposes and to promote food reformulation (WP5); 3) integrated actions in pre-school and school settings (WP6) and 4) improvement in implementation of interventions to promote nutrition and physical activity for pregnant women and for families with young children (WP7). WP6 is focusing on helping Member States to identify ways to create healthier environments in kindergartens and schools. It aims to provide guidance on policy options and initiatives at different levels for facilitating more effective measures in the countries. In this regard, WP6 collects and analyses existing good practices from WP6 partner member states based on a standardized protocol.
