Burden of disease from hypercholesterolemia in Portugal

Cardiovascular diseases are the main cause of death in Portugal, in developed countries and indeed, worldwide. Hypercholesterolemia is a major risk factor for these diseases. What are the potential health gains to be obtained by reducing the prevalence of hypercholesterolemia in the Portuguese population? How are they to be estimated and quantified? Studies of the burden of disease aim to measure and evaluate the impact of a disease or group of diseases on overall levels of health. Although they do not strictly speaking constitute an economic evaluation, since no specific interventions are analyzed, burden of disease studies do provide an accurate picture of a specific health problem and its magnitude, as well as an indication of changes in health policy and in preventive or corrective measures that might lead to improvement. This paper reports the results of a study of the disease burden of hypercholesterolemia in Portugal, calibrated for data from the year 2000. In this study, the disease burden is estimated as the component attributable to hypercholesterolemia in DALYs (disability-adjusted life years). DALYs are a measure used by international organizations such as the World Health Organization and the World Bank.
