Physical activity should be more than 1 hour/day and TV/media consumption less than 1 hour/day.

Main questions are:

Do children differ in intervention and control kindergartens according to their nutrition behaviour? Do children in the intervention kindergartens have a higher physical training than such in the control kindergartens? Data were collected with a standardised questionnaire.
