Context. The metabolic syndrome is a profound, systemic impairment of the metabolism of lipids, carbohydrates and branched amino-acids, affecting specially obese people. Recently, many studies outlined the presence of the metabolic syndrome, also in non obese persons. Objective and design. To assess the relationship between insulin resistance and the cardiovascular component of the metabolic syndrome in a group of young, non obese subjects using a cross sectional study. Subjects and methods. We enrolled 103 subjects with body mass index < 30 Kg/m2, without metabolic syndrome to whom fasting glucose, triglycerides, high density lipoprotein cholesterol, insulinemia, waist circumference and arterial pressure were recorded in a crosssectional approach. Insulin resistance was evaluated using the homeostasis model assessment for insulin (HOMA-IR) index. Statistic data processing included Pearson relation and multiple regression (backward method), using the SPSS version 21 software. Results. A significant relationship between waist circumference, diastolic blood pressure and HOMA-IR is found. High value of HOMA-IR (>2.6) was more frequently in men (p=0.011). The incidence of the 2 metabolic components mentioned above was higher in the high value HOMA-IR group: 33% vs. 7% in women and 50% vs. 4% in men. Multiple regression showed a strong correlation between HOMA-IR and waist circumference (p<0.001) and diastolic blood pressure (p=0.008) that was maintained inside the women group (p=0.016 and p=0.032, respectively). In men, HOMA-IR correlated with waist circumference (p=0.031). Conclusion. We found a significant interdependence between waist circumference, diastolic blood pressure and HOMA-IR. Based on our results, we consider that lifestyle intervention should start as soon as abnormal waist circumference is recorded.

Keywords: metabolically non-obese young population, HOMA-IR, waist circumference, diastolic blood pressure.
