[Results] The average prevalence of BMI, overweight, obesity and fatty liver were 24.56, 42.11%, 15.29% and 34.17% in males and 22.50, 21.94%, 6.84% and 10.10% in females, respectively, female. The prevalence of overweight and obesity among fatty liver patients was 53.21% and 30.28% in males and 51.72% and 20.69% in females, respectively, all higher than those without fatty liver.
