The Prevalence and Predictors of Elevated Serum Aminotransferase Activity in the United States in 1999-2002

Abstract

The current prevalence of elevated ALT activity in the United States (8.9%) is more than double that of previously available estimates. This prevalence is very high (7.3%) even among persons without viral hepatitis C or excessive alcohol consumption and is strongly associated with risk factors for nonalcoholic fatty liver disease.
