Metabolic syndrome and nonalcoholic fatty liver disease in a Spanish population

Abstract

The MetS is quite frequent in the general population, although its prevalence varies considerably according to the criteria used for its definition. The MetS is associated with NAFLD, with the WHO definition being the best to determine its presence, probably because of the inclusion of insulin resistance as a main component. Unification of criteria is needed to adequately compare the prevalence of MetS and its relationship with NAFLD in different population groups.
