Abstract：Objective To investigate the correlation between non alcohol fatty liver disease (NAFLD) and body mass index (BMI) as well as patient's age in Dalian.Methods The 14,655 subjects who underwent health examination were divided into different age groups at an interval of 10 years,moreover,according to BMI (BMI ＜ 18.5kg/m2,18.5kg/m2 ～23.9kg/m2,24.0kg/m2 ～ 27.9kg/m2,≥28.0kg/m2),they were divided into four groups.The differences of incidence rate of NAFLD were observed and compared among different age groups and different BMI groups.Results There were significant differences in incidence rates of NAFLD in the same age group between males and females (P ＜ 0.05).At the same BMI group,the incidence rate of NAFLD in 40 ～ 60 years group of males was higher,however,which was higher in ＞ 50 years group of females.Except for ＞ 70 years group,the incidence rate of NAFLD in the other age groups of males were higher than that of females,moreover,except for BMI ＜ 18.5kg/m2 group,the incidence rate of NAFLD in the other BMI groups of males were higher than that of females,Conclusion The incidence rate NAFLD is increased with the increasing of BMI,moreover,with the increasing of patient's age the incidence rate of NAFLD has an increasing trend.The incidence rate of NAFLD in males is higher than that in females.Except for ＞ 70 years group,the incidence rates in the other age groups and BMI groups in males are higher than those in females.
