Influence of Gender, Race, and Ethnicity on Suspected Fatty Liver in Obese Adolescents

Abstract

In a national, school-based sample of obese adolescents, boys were 6 times more likely than girls to have an unexplained elevated ALT. Given that participants were well and causes of chronic liver disease were excluded, we speculate that obese adolescent boys have an increased prevalence of fatty liver compared with obese adolescent girls. This population-based study also supports the hypothesis that NAFLD is more common in Hispanic adolescents. These findings have implications for both disease screening and studies of fatty liver pathophysiology.
