[Criteria catalogue to systematize conceptual approaches in universal prevention of childhood overweight : Methodological approach and first results].

BACKGROUND: Overweight and obesity are serious health risks for children and adolescents. Hence, various prevention projects have been initiated and implemented. Until now, a systematic overview of interventions in different settings has been lacking. AIM(S)/RESEARCH QUESTION: The aim of the "Prevention of child overweight" project (SkAP-project) is to prepare a systematic overview of the conceptual approaches used in universal prevention of overweight among children and adolescents. First of all, a comprehensive criteria catalogue will be developed based on systematic searches. In the next step the criteria catalogue will be applied to identify and characterize conceptual approaches. DATA AND METHODS: Criteria to describe conceptual approaches as well as determinants of childhood overweight were determined by systematic searches. The searches included relevant data bases and were further expanded by internet and hand search. Three settings (kindergarten, school and communities) and families are addressed by the systematic searches. Additional non-setting specific searches were conducted. RESULTS: A comprehensive criteria catalogue was developed, which allows a detailed analysis of conceptual approaches. This catalogue covers further quality criteria as well as determinants of childhood overweight. DISCUSSION: Currently, the criteria catalogue is being employed. Although the detailed analysis of conceptual approaches can be regarded as advantage of the criteria catalogue, there are also some limitations, such as the lack of necessary information provided in publications. Overall, the application will reveal an overview regarding universal prevention in childhood overweight, which is still lacking, and will support development in this field.
