Objectives To explore the relationship between Fatty Liver disease and Gender, Age, body mass index (BMI) 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 analysed 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%, P < 0.01). The trend of prevalence of Fatty Liver was growing with the age increasing (P < 0.01). 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 statistically significant (p < 0.01) for both normal weight group and overweight group, while p > 0.05 for 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 (P < 0.01). 5) Multiple regression analysis showed that Age, FBG, TG, HDL-C, DBP, UA, Overweight and Obesity were risk factors for fatty liver (OR: 1.032, 1.215, 1.379, 1.703, 1.036, 1.005, 6.347, 30.543, respectively).
Conclusions 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.
