Aim: we evaluate the effectiveness of fat mass, BMI, and other obesity indicators(waist circumference, Waist-to-Hip ratio)to predict all-cause and cause-specific mortality
scientific rationale: it is still unclear which indicator of obesity is highly close to all-cause mortality and cause-specific mortality.
public health impact: The founding of our study will help us control obesity and choose suitable indicators of obesity
project duration:3 years
