Evidenzbasierung von Primärprävention am Beispiel einer Interventionsstudie zum kindlichen Übergewicht

BackgroundThe most challenging step on the road map to primary prevention is transferring evidence-based intervention modules into practice and achieving their sustainability. This road map is illustrated by an epidemiological intervention study targeting lifestyle-related disorders in children.MethodsStarting from the health problem of interest a suitable target group is identified that can be reached effectively and in whom the most profound effects are to be expected. Modifiable risk factors and realistic targets of the intervention are specified.ResultsThese determine the outcome measures as the main evidence of the effectiveness of the intervention. Target groups and outcome measures are the cornerstones of the study design and the definition of comparison groups. If the intervention requires the active involvement of participants, then the program should follow participatory approaches and take into account the sociocultural and living environment.ConclusionsEvaluation is the key component of any intervention. It involves assessing the structure and process and evaluating the outcome according to rigid scientific criteria
