A Serious Game for the Prevention of Obesity in School Children-Impact of Parent's Involvement: A Randomized Controlled Trial

Serious games convey information and use interactive components to reinforce and train behaviours. A serious game addressing nutrition, physical activity and stress coping-the Kids Obesity Prevention Program (KOP)-was previously evaluated for efficacy in children. This study aimed at evaluating the KOP-game regarding: (i) its acceptance and efficacy with respect to parents of primary school children receiving the same game intervention as the children; and (ii) whether the children could benefit by parental involvement. A randomized controlled trial with two groups of children aged 9 to 12 years was conducted which included a 6-month follow-up period. All children played the game twice in two weeks. In the family-intervention group, the parents additionally played the game. The primary outcome was the gain in knowledge in parents and children measured with a pretested questionnaire. The secondary outcomes were knowledge maintenance as well as several behavior changes. Parents and children in both groups improved and maintained their knowledge equally. The KOP-game increases knowledge of nutrition in children independently of the involvement of their parents. KOP games are well accepted in children; further research should examine the structured involvement of parents.

Automated summary

This study evaluated the acceptance and effectiveness of the Kids Obesity Prevention Program (KOP) game among parents of primary school children, and investigated the impact of parental involvement on children. The results showed that the KOP game increases children's knowledge of nutrition regardless of parental involvement.
