Cross-sectional	No intervention	a cross-sectional study.

Primary Outcome Measures

Name	Time	Method
circulation concentration of glucose	less than 4 hours	Glucose (mmol/L) was measured in less than 4 hours after sample collection
circulation concentrations of 5 minerals	less than 3 years	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)
circulation concentrations of 4 types of lipids	less than 4 hours	TG, TC, LDLC, and HDLC (mmol/L) were measured in less than 4 hours after sample collection

Secondary Outcome Measures

Name	Time	Method
body mass index	less than 1 month	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).
