About the project

In this research project funded by the Norwegian Research Council, the effects of one Norwegian and one European school-based intervention will be evaluated.

The Norwegian HEIA study has tested different measures targeting diet and physical activity among 11 to 13 year olds and their parents. Maternal and paternal education have also been surveyed.

The European study UP4FUN is an intervention over five weeks among 10-12 year olds, including Norwegian children. The goal has been to reduce and break up sitting time both at school and at home, and to find strategies for how to involve families.

As part of the post doctor project, new questionnaires for measuring family processes potentially related to diet will be developed and tested.


The main objective is to evaluate school-based obesity prevention interventions by gender, socio-economic status and parental involvement, and to assess family processes influencing energy balance-related behaviours.


Inconsistent effects of school-based obesity prevention interventions may be related to how different subgroups perceive them. Gender, socio-economic status and degree of parental involvement seem to influence the effects of interventions. To develop intervention strategies that improve energy balance-related behaviours, more research is needed investigating mediating factors in the family and home environment. Such factors may be parent-child communication and parenting practices as elements of parenting styles.


  • Investigate whether there are long term effects of a Norwegian multi-component, school-based intervention study on energy-balance related behaviours from age 11 to 15, and if effects differ by gender, socio-economic status and parental involvement.
  • Investigate degree of parental involvement in a European school-based intervention study on sedentary behaviour in adolescents developed with focus on reaching the parents, and whether this varies by gender, socio-economic status and country.
  • Develop three instruments (forms) measuring family processes influencing adolescents’ diet.
