Definition of NAFLD

◼ There is evidence of hepatic steatosis either by

imaging or by histology and no causes for

secondary steatosis

NAFLD is a highly prevalent form of FLD

caused by over-nutrition

NAFLD is an acquired metabolic stress-

induced liver diseases associated with insulin

resistance and genetic susceptibility

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

Definition of NAFLD

◼ There is evidence of hepatic steatosis either by

imaging or by histology and no causes for

secondary steatosis

NAFLD is a highly prevalent form of FLD

caused by over-nutrition

NAFLD is an acquired metabolic stress-

induced liver diseases associated with insulin

resistance and genetic susceptibility

Definition of NAFLD

◼ There is evidence of hepatic steatosis either by

imaging or by histology and no causes for

secondary steatosis

NAFLD is a highly prevalent form of FLD

caused by over-nutrition

NAFLD is an acquired metabolic stress-

induced liver diseases associated with insulin

resistance and genetic susceptibility

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

Definition of NAFLD

◼ There is evidence of hepatic steatosis either by

imaging or by histology and no causes for

secondary steatosis

NAFLD is a highly prevalent form of FLD

caused by over-nutrition

NAFLD is an acquired metabolic stress-

induced liver diseases associated with insulin

resistance and genetic susceptibility

Incidence of NAFLD in Shanghai

◼ 5226 non-drinking workers without US-fatty liver at

baseline

◼ After 2-year follow-up 310 pts (62) were found to

have NAFLD

◼ Incidence of NAFLD (3 new cases100 people year) is equal to

that in Dionysos study

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

Definition of NAFLD

◼ There is evidence of hepatic steatosis either by

imaging or by histology and no causes for

secondary steatosis

NAFLD is a highly prevalent form of FLD

caused by over-nutrition

NAFLD is an acquired metabolic stress-

induced liver diseases associated with insulin

resistance and genetic susceptibility

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

Incidence of NAFLD in Shanghai

◼ 5226 non-drinking workers without US-fatty liver at

baseline

◼ After 2-year follow-up 310 pts (62) were found to

have NAFLD

◼ Incidence of NAFLD (3 new cases100 people year) is equal to

that in Dionysos study

◼ The baseline BMI serum triglyceride and their subtle

gain during follow-up were independent predictors of

incident of NAFLD Fan JG et al Hepatol International 2010

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome

◼ NAFLD is emerging into a new and major health problem in Chinese

NAFLD is not just a lsquoWesternrsquo problem

◼ Prevalence of fatty liver increased rapidly in past decades with obesity and MetS pandemic in China

◼ Fatty liver is more often associated with obesity than with alcoholism

◼ Chronic HBV infection do not account for increased trend of fatty liver and fatty liver increased in CHB as well

◼ Cardiovascular and diabetic risk may compete with liver disease-related risk in dictating the final outcome
