DAGIS (Increased Health and Wellbeing in Preschools) is a research project interested in energy balance-related behaviours (EBRBs) and stress regulation in Finnish preschool children (3-6 year olds). Energy balance-related behaviours include sedentary behaviours, physical activity and dietary behaviours. As well as studying preschool children, DAGIS will research the work wellbeing of preschool personnel.


DAGIS has three main aims:

  1. To improve EBRBs of children.
  2. To improve work wellbeing and the lifestyle of preschool personnel.
  3. To create preschool as an environment for healthy lifestyle and wellbeing for children and personnel.
