Alcohol Attributable Fractions and Costs in Portugal

Aim: This study estimates alcohol attributable fractions which are used to obtain a measure of health expenditures related to alcohol misuse in Portugal. Methods and Sources: Studies estimating alcohol-attributable expenditures focus usually on specific diseases or conditions. This study takes a broader approach by examining all expenditures considered as being attributable to excessive drinking, i. e., those resulting from utilization directly and indirectly related to alcohol associated diseases. Unlike studies using the relative risk methodology, where population alcohol-attributable fractions (or etiologic fractions) are based on epidemiological studies identifying potential causes of death and disease associated with alcohol excessive consumption, this study has adopted the microeconometric methodology which gets estimates of attributable fractions running econometric regressions of the annual costs of medical care (medical appointments or hospital admissions) for individuals. It has an advantage over the risk approach in that it allows to control for the effect of factor
