Concentrations of serum Vitamin A, Vitamin E, and Vitamin D were log-transformed and then standardized
Each component of metabolism syndromes was categorized based on NCEP: ATP III guidelines. Waist circumference was categorized into low (< 102 cm in men or < 88 cm in women) and high (≥ 102 cm in men or ≥ 88 cm in women) groups, and the low group was used as the reference; triglyceride was categorized into low (< 150 mg/dL) and high (≥ 150 mg/dL) groups, and the low group was used as the reference; high-density lipoprotein was categorized into low (< 40 mg/dL in men or < 50 mg/dL in women) and high (≥ 40 mg/dL in men or ≥ 50 mg/dL in women) groups, and the high group was used as the reference; blood pressure was categorized into low (systolic blood pressure < 130 mmHg and diastolic blood pressure < 85 mmHg) and high (systolic blood pressure ≥ 130 mmHg or diastolic blood pressure ≥ 85 mmHg) groups, and the low group was used as the reference; fasting plasma glucose was categorized into low (< 110 mg/dL) and high (≥ 110 mg/dL) groups, and the low group was used as the reference
