kids obesity prevention program part 2

Conditions: Obesity; Child

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. as children do not decide alone what they eat - but their parents - the involvement of parents in the intervention appears to be very important to reach a sustained effect. 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 and a reflexion exercise about leisure behaviour. the game consists of two sessions, having each a duration of about 35 minutes. the aim of the kop-1 study was to evaluate the game regarding its acceptance and efficacy in a cluster-randomized controlled trial in a primary school setting in children aged 9 to 12 years. the aim of the here presented kop-2 study is to evaluate the game regarding its acceptance and efficacy in a randomized controlled trial in parents of primary school children aged 9 to 12 years receiving the kop-1 intervention. therefore, 4th grade pupils of the same school will be randomly allocated to an intervention and a control group. both groups will play the game within two weeks, whereas the intervention group will take the game home on a tablet computer to play it with their parents in between session 1 and 2. at baseline, one day after session 2 and at four weeks follow-up, measurements will be performed in pupils and the parents of the intervention group. the primary outcomes of the study are the gain of knowledge (nutrition, psychosocial aspects) in parents and children, measured by a self-constructed questionnaires tailored specifically for the serious game. secondary outcomes are the interaction of pupils and their parents for the intervention group, 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.
