The presence of metabolic syndrome, IFG, HOMA-IR >2.5, and hsCRP >1000 μg/mL were singly considered as dependent variables.

All models were controlled for education, marital status, working status, current smoking, family history of diabetes, waist circumference, physical activity score, medications. All Med Diet items were added. The presence of metabolic syndrome was added in IFG, hsCRP, and HOMA-IR models.

MetS, metabolic syndrome; IFG, impaired fasting glucose; B, regression coefficient; 95% CI, 95% confidence intervals; NS, not significant; BMI, body mass index; Med Diet, Mediterranean diet; HOMA-IR, homeostasis model assessment of insulin resistance; hsCRP, high-sensitivity C-reactive protein.
