Objective:To determine the prevalence of fatty liver in physical examination group of Chongqing

and to analyze its risk factors.Methods:Total 13610 persons who underwent physical examination and laboratory tests

were measured the level of body mass index(BMI)?blood pressure(BP)?blood lipids(TC&TG)?glucose(FBG)and liver function(ALT&AST).The results of cases of fatty liver were compared with those of non-fatty liver.Results:The ratio of fatty liver was16.9%

and the prevalence of fatty liver in male was significantly higher(22.4%) than that of in females(8.69%)

about 2.6 times.The prevalence of fatty liver was increased with age.There was significant difference between the fatty liver and non-fatty liver groups in their BMI?BP?TC?TG?FBG?ALT and AST.The morbidity of obesity?dyslipidemia?hypertention?and diabetes mellitus in the fatty liver group were significantly higher than in non-fatty liver.The ratio of hepatitis B carrier was no significant difference between the two groups.Conclusion:Obesity?diabetes mellitus?hyperlipidemia and hypertention may be independent risk factors of fatty liver.The mildly to moderate abnormal hepatic functions could be found in patients with fatty liver.To lose the body weight?control the hyperlipidemia and maintain normal glucose?blood pressure are important measures to prevent the fatty liver.
