In order to clasify our 124 SF subjects as metabolically healthy, we used well-defined criteria: absence of abdominal obesity based on waist circumference, absence of metabolic syndrome components, normal lipid values, normal fasting glucose concentrations, normal C-reactive protein concentrations and absence of IR as evaluated by the Matsuda index (Table 3) [4,32,38,39]. This evidence concerns the gene CRP and metabolic syndrome.
