Analysis of prevalence rate of fatty liver and it's related factors for science researchers in Beijing

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 it's early intervention.Methods A total of 445 cases were included in this study which was carried out in our hospital Check-up Center in Nov.2012,with complete information developed.The physical examination results were analyzed with statistical method.Results(1) There were 73persons diagnosed of fatty liver disease by B-type ultrasonic scanning in this study.The total prevalence rate of fatty liver was 16.4%.The prevalence rate in male and female were 17.0%,15.0%(P 0.05),respectively.The trend of prevalence of fatty liver was growing with the age increasing(P 0.05).(2) For each age group,the prevalence rate of fatty liver increased with level growth of BMI(normal,overweight,obesity,P 0.01).The difference of prevalence rate among all age sub-groups proved no statistically significant(P 0.05) for normal weight group,overweight group and obesity group.(3) Single factor analysis showed that BMI,blood pressure,blood lipid,FBG,UA and ALT from the fatty liver group was significantly higher than that of the non fatty liver group(P 0.01).(4)Prevalence of metabolic syndrome was higher in fatty liver group than in non fatty liver group(43.8% vs.6.5%,P 0.01).(5) Multiple regression analysis showed that sex,dyslipidemia,UA,overweight,obesity and blood pressure classification(high-normal blood pressure,high blood pressure level Ⅰ,high blood pressure level Ⅱ) were risk factors for fatty liver(OR: 3.445,7.264,1.008,5.642,8.710,2.228,3.496,3.885,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 of fatty liver.
