Abstract: Objective To explore the related factors of controlled attenuation parameter (CAP) of liver obtained by FibroScan examination in healthy individuals. Methods The CAP was obtained by FibroScan in208healthy persons, and the main biochemical indexes, gender, age, body mass index (BMI), waist-hip ratio (WHR), waist-height ratio were collected at the same time, and the relationship between CAP value, these common indicators was analyzed. Results Multiple linear regression analysis showed that CAP value was significantly correlated with BMI, WHR, age (for BMI, β=0.280, P=0.0002;for WHR, β=0.206, P=0.0059;for age, β=0.192, P=0.0022);And the regression equation established after multiple linear regression analysis, partial least squares regression were CAP=-137.70+9.40*TG+5.40*BMI+176.34*WHR+1.60*age, the adjusted CAP=-92.11+10.67*TG-10.25*HDL+4.45*BMI+196.25*WHR+1.03*age. Conclusions The range of CAP value is affected by BMI, WHR, and age in the general population, the adjusted regression equation is more better to predict the CAP value of the liver
