identified across US, Europe and Asia. The reported prevalence of NAFLD among the general population ranged between 22%-37% (US: 22%-32%; Europe 29-37%; Asia: 29.7%). Biopsy-confirmed NASH was reported between 16%-70% among the NAFLD population (US: 42-68%; Europe 16-45%; Asia: 70%). Two US studies reported the prevalence of NASH amongst the general population (0.05%-0.7%) using ICD-9 (571.8)/10 codes connected to NASH, as a proxy. Among the identified studies, a variety of comorbidities were reported in the study populations; diabetes, obesity, hypertension. The reported prevalence of NASH amongst type 2 diabetic patients and obesity patients, ranged between 57%-64% and 14%-47%, respectively. ConCluSionS: There is vast variability in the reported prevalence of NAFLD/NASH globally, however the findings are comparable to recently published meta-analyses. Although biopsy is considered the gold standard diagnosis for NASH, its limited use owing to associated procedural risks may not give us the true prevalence of NASH. Therefore, there is a need to achieve consensus in terminology, disease definition and diagnostic methods to better determine the true prevalence of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
