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
◼ The baseline BMI serum triglyceride and their subtle
gain during follow-up were independent predictors of

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

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

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
Fan JG J Hepatol 2009 JGH 2013
Thanks for your attentionThanks for your attention
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

Criteria for obesity and MetS
ethnic differences
◼ Only 2-3 of Asians classified as obesity by Western criteria
◼ All Asian populations studied had a higher BF at a lower BMI compared to Caucasians
◼ For the same BF their BMI was 3-5 units lower compared to Caucasians
Modified definition for Asians

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

Prevalence of NASH in Shanghai
Bao-Steel Company A total of 59131 employees of Shanghai Bao-Steel Company
were undergone biannual health check-up
Prevalence of abnormal ALT was 46 without obvious
changes between 1995 and 2002
Prevalence of fatty liver in patients with abnormal ALT was
increased between from 259 to 514
Prevalence of NAFLD among 14646 subjects was 131 in
2002 percentage of abnormal ALT among NAFLD patients
was 164
Prevalence of NASH might be around 22 in health
check-up adults in 2002

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

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

Normal liver NAFL NASH plusmn fibrosis Cirrhosis
Annual incidence of NAFLD 3-4
60 can reverse NAFLD by lifestyle intervention
25 progress from NAFL to NASH and have fibrosis progression in 3 yrs
Spontaneous reversal of NASH uncommon without intervention
Fibrosis progression 1 stage in 7 yrs in NASH 1 stage in 14 yrs in NAFL
No data on reversal of cirrhosis
HCC
bull Absence of cirrhosis reported in 30-50 of NAFLD-associated HCC in Asians
bull The absolute risk of HCC in non-cirrhotic patients is lt01 per year
bull 1-4 per year

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
