Usefulness of differentiating metabolic syndrome into visceral fat type and subcutaneous fat type using ultrasonography in Japanese males

Background Although metabolic syndrome (MS) is likely to be associated with nonalcoholic fatty liver disease (NAFLD), visceral fat type MS and subcutaneous fat type MS have not been distinguished. In this study, we divided persons with MS into those with visceral and subcutaneous fat types by ultrasonography (US), and elucidated differences between these types of MS in Japanese males.
