Brief Summary

Obesity and its associated comorbidities are becoming a key and rapidly growing public health problem. The cause of obesity is an imbalance between energy intake and energy expenditure in favor of the former. Childhood and adolescence are seen as critical time for its development. It is therefore crucial to provide both prevention and treatment actions already during childhood. The prevention and treatment weight-management programs in children focus on improving diet, eating behaviours, psychosocial aspects and increasing physical activity. One important basic requirement for any weight-management program is, that both children and their families are motivated and ready for change. Video games, including exergames, serious games or combined approaches offer additional chances in the treatment and prevention of obesity by approaching children in their environment and motivating them to deal with life-style topics.

The investigators developed a motion-controlled serious game for children aged between 9 and 12 years, addressing all the three core areas nutrition, physical activity, and psychosocial factors. In addition to the motion control, a tablet is used for knowledge-based and cognitive tasks. In comparison to other studies the nutrition part not only deals with the food pyramid but also with the energy density of foods and liquids and offers a self-reflexive diagnostic tool to analyse daily food intake. Moreover, psychological aspects, especially stress and stress-coping strategies are addressed e.g. by relaxation-exercises. The game consists of two sessions, having each a duration of about 35 minutes.

The aim of this study is to evaluate the program in a cluster-randomized controlled trial in a primary school setting in children aged 9 to 12 years. Therefore, six 4th grade classes of the same school will be randomly allocated to an intervention and a control group. The intervention group will play the game within two weeks, whereas the control group will receive basic information. At baseline, two weeks after baseline and at four weeks follow-up, measurements will be performed. The primary outcome of the study is the gain of knowledge (nutrition, psychosocial aspects) measured by a self-constructed questionnaires tailored specifically for the serious game. Secondary outcomes are the acceptance of the game, changes of nutrition behaviour, physical activity and intentions of the children to follow a healthy lifestyle, measured by mostly validated questionnaires.

Arm && Interventions

Group	Intervention	Description
Intervention	The serious game KOP	Children in a primary school, aged between 9 and 12 years, play the serious game (two sessions, duration of each session 35 minutes, within two weeks). The game equips the children with knowledge about the core areas nutrition, physical activity, and psychosocial factors.

Primary Outcome Measures

Name	Time	Method
Knowledge of the children about nutrition and psychosocial aspects by a self-developed questionnaire specific for the serious game	Change between baseline and two weeks after the baseline measurement

Secondary Outcome Measures

Name	Time	Method
Acceptance of the serious game by the children using a self-developed questionnaire specific for the serious game	At baseline and directly after the end of the second session of the game (on average two weeks after baseline measurement)
Nutrition Score (Ernährungsmusterindex) by Kleiser et al., 2007 used in the KIGGS cohort (Studie zur Gesundheit von Kindern und Jugendlichen in Deutschland)	Change between baseline and four weeks follow-up (on average 6 weeks after baseline measurement))	Parents and children are independently asked to report the food frequencies for key foods in order to calculate the Ernährungsmuster index
Food frequency of specific foods which are addressed in the serious game	Change between baseline and four weeks follow-up (on average 6 weeks after baseline measurement))	Parents and children are independently asked to report the food frequencies of specific foods
Physical activity using a validated questionnaire filled in by the children and also the parents	change between baseline and four weeks follow-up (on average 6 weeks after baseline measurement))	Parents and children are independently asked to fill in the questionnaire
Intentions of children to stick to a healthy lifestyle by using a tailored questionnaire specific for the contents of the serious game	Change between baseline, and two weeks after baseline measurement, and four weeks follow-up
