  1. *Values are adjusted for age.
  2. ** Mean (SD).
  3. Abbreviations: Fp-gluc, fasting plasma glucose; BP systolic, systolic blood pressure; BP diastolic, diastolic blood pressure; HDL-C, high density cholesterol; Trigly, triglycerides; TFR, transferrin receptor; Hs-CRP, high sensitivity c-reactive protein.
  4. Components of MetS.
  5. 1. Waist >102 cm (male) or >88 cm (female).
  6. 2. FP-glucose ≥ 5.6 mmol/L.
  7. 3. Systolic blood pressure ≥ 130 mmHg or diastolic ≥ 85 mmHg or antihypertensive medication.
  8. 4. HDL–cholesterol < 1.03 mmol/l (men) or < 1.29 mmol/l (women) or medication for dyslipidemia.
  9. 5. Triglycerides >1.7 mmol/l or medication for dyslipidemia.
  10. Current use of alcohol was consireded low with no use of alcohol, moderate with use of <2 portions/day and high with use of >2 portions/day. Physical activity was considered to be high in subjects who exercised daily at least 30 minutes in their leisure time, moderate in subjects who exercised at least three times per week, and low if exercising frequency was less than three times per week.
