NAFLD is an emerging problem in Asia, with raising prevalence and strong impact on the health care system. More and more people will suffer from not only the liver impairment of NAFLD but also the associated metabolic diseases e.g. DM and hypertension. The incidence of DM, hypertension, coronary heart diseases (CHD) and stroke will increase together with the prevalence of NAFLD and the health service expenditure will rise in coming decades. However the prevalence of and the metabolic diseases associated with NAFLD are not well studied in Asian populations. The objective of this project is to systematically review the articles related to NAFLD.
