The WHO criteria published in 1999 required the presence of dysglycemia, which comprises impaired glucose tolerance, impaired fasting glucose or insulin resistance, and two of the following conditions: central obesity—waist-to-hip ratio > 0.90 (men), >0.85 (women) or body mass index > 30 kg/m2; dyslipidemia—triglycerides (TG): ≥1.695 mmol/L and high-density lipoprotein cholesterol (HDL-C) ≤ 0.9 mmol/L (men), ≤1.0 mmol/L (women); blood pressure: ≥140/90 mmHg; microalbuminuria: urinary albumin excretion ratio ≥ 20 μg/min or albumin–creatinine ratio ≥ 30 mg/g [4]. This evidence concerns the gene ALB and Impaired glucose tolerance.
