circulation concentration of glucose
Glucose (mmol/L) was measured in less than 4 hours after sample collection
Time frame: less than 4 hours
circulation concentrations of 4 types of lipids
TG, TC, LDLC, and HDLC (mmol/L) were measured in less than 4 hours after sample collection
Time frame: less than 4 hours
circulation concentrations of 5 minerals
all samples were stored at minus 75 degrees Celsius until ready for analysis collectively on a ICP-MS machine for calcium, cobalt, iron, selenium, and zinc (ng/ml)

body mass index
body weight (kg) and hight (m) were measured when the volunteers were visiting the health examination center, and the body mass index was calculated later by the formula of body weight/ hight/ hight (kg/m\^2).
