Gesundheitsökonomische Aspekte von Übergewicht und Adipositas

Zusammenfassung

Dieser Beitrag gibt einen Überblick über gesundheitsökonomische Aspekte von Übergewicht und Adipositas. Zunächst werden die Methoden der Messung von direkten und indirekten Krankheitskosten sowie die Ergebnisse von Krankheitskostenstudien aus der internationalen Literatur vorgestellt. In diesen Studien wurde der Anteil der durch Übergewicht und Adipositas verursachten Kosten an den Gesamtkosten der Gesundheitsversorgung meist auf zwei bis sechs Prozent geschätzt. Anschließend wird aufgezeigt, wie mit den Methoden der ökonomischen Evaluation die Kosteneffektivität präventiver Gesundheitsleistungen beurteilt werden kann. Probleme ergeben sich dabei aus der Notwendigkeit der Schätzung langfristiger Auswirkungen auf die Kosten und Effekte einer Vielzahl assoziierter Folgekrankheiten. In der Literatur vorhandene ökonomische Evaluationsstudien präventiver Gesundheitsleistungen weisen auf eine sehr günstige Kosteneffektivität hin. Zur Steigerung der Wirtschaftlichkeit der Gesundheitsversorgung sollten vermehrt kosteneffektive Maßnahmen zur Prävention von Übergewicht und Adipositas entwickelt und eingesetzt werden.

Summary

This article provides an overview of economic aspects of overweight and obesity. After describing the methods of measuring direct and indirect costs, results of cost-of-illness studies from the international literature are presented. In these studies, the proportion of direct health care costs caused by overweight and obesity has been estimated between 2 % and 6 %. Subsequently, this paper describes the methods that can be used to analyse the cost-effectiveness of preventive services. Problems arise from the need to estimate long-term effects of prevention on costs and health consequences of multiple associated diseases. Economic evaluations of preventive services published in the literature often report very favourable cost-effectiveness ratios. In order to increase the efficiency of health care, more costeffective preventive services for overweight and obesity should be developed and used.
