Prevalence rate and risk factors on fatty liver among iron and steel workers

Objective To investigate the prevalence and risk factors on fatty liver among iron and steel workers and to provide evidences for preventive measures. Methods A stratified sampling study on the epidemiological feature of fatty liver was conducted among 1992 workers from 4 factories of Ma'anshan iron and steel general company. Results The prevalence rate of fatty liver was 14.96% in 1992 workers, with 15.96% in males and 11.83% in females, respectively. The rates of fatty liver were significant in different sex, age and career ( P <0.05). The differences of WHR, BMI, SBP, DBP, TC, TG and FSG between fatty livers group and non-fatty livers group were significant ( P <0.05). The incidences of fat intake, snacks, drinking, exercise, taking car, riding bicycle, mental work hypertension in the two groups were also significant ( P <0.05). Conclusions The prevalence of fatty liver was similarly high among iron and steel workers. These results implied that a comprehensive intervention should be taken in the prevention of fatty liver.
