Plain English Summary

Background and study aims
The aim of this study is to test a school-based, family-involved scheme to promote health behaviours that help to prevent obesity in children aged 10-12 years old across Europe. The scheme, called Up4fun, aims to reduce sitting time in school and at home (with special emphasis on TV and PC/electronic games)

Who can participate?
10-12 year old children at selected schools.

What does the study involve?
Participating schools will be randomly allocated to either the intervention group or the control group. The control group schools were asked to continue with their usual school curriculum. The intervention group schools took part in the Up4fun scheme for 6 weeks in the fall semester of 2011.
The teachers involved will be given training and are requested to spend one school hour (45 minutes) to teach a pre-planned lesson each week for 5 weeks. Weekly newsletters (6 in total) for the parents and pre-planned homework for the children will be handed out by the teacher. The parents will be fully informed about the contents and the aims of the study and will be asked for consent for the participation of their child. The pupils will complete questionnaires about their sedentary (sitting) behaviours, physical activity and dietary habits. Additionally, some of the children’s physical activity levels will be measured using accelerometers. The parents will also complete a questionnaire about their own and their child’s nutritional and physical activity.

What are the possible benefits and risks of participating?
The scheme may help to reduce the prevalence of obesity and improve public health. No risks are involved, but the questionnaires take time and might be boring to fill out, a few questions might be uncomfortable for some to answer.

Where is the study run from?
The study is run from centres in Belgium, Germany, Greece, Hungary and Norway. The lead centre is University of Agder, Norway. The project leader is based in VU University Medical Center, Amsterdam, the Netherlands.

When is the study starting and how long is it expected to run for?
From September 2011 to run for 6 weeks.

Who is funding the study?
The European Commission.

Prevention of excessive weight gain by reducing sedentary behaviour


The intervention, including about 10 schools (5 intervention schools and 5 control schools) in each of the 5 participating countries primarily aiming at reducing sitting time in school and at home (with special emphasis on television and personal computer (PC)/electronic games), will last for 6 weeks in the fall semester of 2011 in the intervention schools. The teachers involved will be given training (1.5 hours) as week 0 of the intervention, and completed materials to be used are provided by project workers. During the project period teachers are requested to spend one school hour (45 minutes) to teach a pre-planned lesson each week for 5 weeks. Weekly newsletters (6 in total) for the parents and pre-planned homework for the children will be handed out by the teacher.
