[The Environmental Burden of Disease Concept].

GOAL OF THE STUDY: Environmental risk factors are of great importance for public health with a considerable but often unused potential for prevention. However, knowledge about the complex associations between the environment and health effects is limited for some risk factors. A concept, which is using the existing evidence on associations between the impact of environmental factors and health effects, is the environmental burden of disease (EBD) concept. The aim of this article is to present the quantification method of the EBD concept and to discuss the advantages and its points of criticism.

METHODS: The EBD concept combines morbidity and mortality data in a single measure (Disability-Adjusted Life Year, DALY) to enable a comparative description of the burden of disease. Life years are used as measurement unit. The environmental share of the total DALYs is quantified by using the attributable fraction.

RESULTS: Despite its increasing application especially in the international context, the method is still criticized, because by summarizing the complex construct of health in one single measurement unit, much important information about quality of life is lost. A further criticism refers to partly arbitrarily set social value choices. Additionally, missing or insufficient data can limit the quality and validity of EBD estimations.

CONCLUSION: A scientific discourse is needed to decide to what extent the EBD approach can and should be used in Germany.
