Prevalence and risk factors of fatty liver in civil servants in Tongzhou district of Beijing

ObjectiveTo investigate the prevalence and important risk factors of fatty liver among civil servants in Tongzhou district of Beijing.MethodsTotally 1 336 civil servants taking physical examination in hospitals were measured for body mass index(BMI),blood pressure(Bp),serum triglyceride(TG),total cholesterol(TC),and blood glucose.Fatty liver cases were diagnosed with type B ultrasonic tomography.Metabolic syndrome(MS)was confirmed according to the criteria of Chinese Diabetes Society(CDS)in 2004.ResultsThe prevalence of fatty liver disease in the civil servants was 30.4% (95% confidence intervalCI:27.9%-32.9%),with a significant gender difference(P<0.01).There was a trend for the prevalence to be increased with age(Z=-8.500,P<0.001).The prevalence was closely related to MS.The servants with MS showed a higher risk of fatty liver(odds ratio=7.23,95% CI:4.86-10.76;P<0.01).After adjusting for age,gender,and interaction of age and gender for MS,logistic regression analyses showed that gender was a confounder factor for the relation of MS and fatty liver(P<0.05).The prevalence of fatty liver increased with the number of MS components(Z=-17.941,P<0.01).ConclusionThe fatty liver prevalence among the civil servants of Tongzhou district in Beijing is relatively high and closely related to age,gender,and the development of MS.Further study is needed to explore the risk factors of fatty liver.
