ABSTRACT

Total 732 subjects aged 30-60 years undergoing health check-up at Beijing Hospital Medical Examination Center in 2009,who had no history of non-alcoholic fatty liver disease (NAFLD) were recruited in the study.According to the quartile of hemoglobin (HGB) level,the subjects were divided into 4 groupsQ1HGB ≤ 131 g/L (n =192),Q2HGB ＞ 131 g/L and ≤ 140 g/L (n =178),Q3HGB ＞ 140 g/L and ≤152 g/L (n =184),Q4HGB ＞ 152 g/L (n =178).All participants were followed up for 4 years,the prevalence rates of NAFLD in groups Q1,Q2,Q3 and Q4 were 8.3％ (16/192),17.4％ (31/178),23.4％ (43/184) and 25.3％ (45/178),respectively (P ＜0.05).Logistic regression showed that the rates of NAFLD in groups Q2,Q3 and Q4 were 2.32 (1.22-4.41),3.36 (1.81-6.21) and 3.72(2.02-6.87) times higher as group Q1 (P ＜ 0.05).Multiple logistic regression analysis showed that the hemoglobin level,TG and BMI were the independent risk factors of NAFLD.
