Study Type : Observational
Actual Enrollment : 1520 participants
Observational Model: Ecologic or Community
Time Perspective: Cross-Sectional
Actual Study Start Date : August 1, 2013
Actual Primary Completion Date : November 30, 2013
Actual Study Completion Date : December 31, 2014

Group/Cohort Intervention/treatment
a cross-sectional study.
Other: No intervention
No intervention.

Primary Outcome Measures :
  1. circulation concentration of glucose [ Time Frame: less than 4 hours ]
    Glucose (mmol/L) was measured in less than 4 hours after sample collection

  2. circulation concentrations of 4 types of lipids [ Time Frame: less than 4 hours ]
    TG, TC, LDLC, and HDLC (mmol/L) were measured in less than 4 hours after sample collection

  3. circulation concentrations of 5 minerals [ Time Frame: 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)

Secondary Outcome Measures :
  1. body mass index [ Time Frame: 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).

  2. circulation concentration of 25OHD [ Time Frame: less than 3 years ]
    all samples were stored at minus 75 degrees Celsius until ready for analysis collectively with ELISA kits (nmol/L)

Biospecimen Retention:   Samples With DNA
Blood samples were collected and separated by centrifugation for supernatant and blood cells.
