Analysis of prevalence rate of fatty liver and it′s related factors for employees of the enterprises

Objective To explore the prevalence rate of fatty liver and the relationship between it and it′s related factors in order to provide evidence for its early intervention.Methods A total of 2386 cases were included in this study which was carried out using our hospital Mobile Physical Examination Vehicle in July 2012,with complete information developed.The physical examination results were analyzed with statistical method.Results (1)There were 356 persons diagnosed of fatty liver disease by B-type ultrasonic scanning in this study.The total prevalence rate of fatty liver was 14.9%.Men had a higher prevalence than women(16.1% vs.4.5%,P0.01).The trend of prevalence of fatty liver was growing with the age increasing(P0.01).(2)For each age group,the prevalence rate of fatty liver increased with level growth of BMI(normal,overweight,obesity,P0.01).The difference of prevalence rate among all age sub-groups proved statistically significant(P0.01)for both normal weight group and overweight group,while P0.05 for obesity group.(3)Prevalence of metabolic syndrome was higher in fatty liver group than in non fatty liver group(P0.01).(4)Multiple regression analysis showed that age,FBG,TG,DBP,UA,overweight and obesity were risk factors for fatty liver(OR:1.299,1.286,1.795,1.376,1.374,5.771,27.206,respectively).Conclusion High blood pressure,overweight,obesity,dyslipidemia and increasing of UA are closely correlated with fatty liver disease.This is to provide an important evidence for early health management program of fatty liver.
