MIGUEL, Viso et al. Insulin resistence, obesity and metabolic síndrome. Cohort CDC Canarian in Venezuela. Salus [online]. 2013, vol.17, n.1, pp.18-24. ISSN 1316-7138.

Obesity is a chronic disease, a public health problem, with high morbidity associated to the insulin resistance (IR). Metabolic syndrome (MS), predicts cardiovascular disease and type 2 diabetes, being obesity and IR the main risk factors. HOMA, is a simple validated marker for IR, non invasive and inexpensive. The objective was to estimate IR and its relation with the nutritional status of canarian-venezuelan adults with and without MS. The sample was comprised of 67 adults (20-84 years old), born in canaries islands and their children older than 19 years of age living in Venezuela, 23 with MS and 44 controls. Anthropometric measurements, blood pressure, fasting glucose, HDL-cholesterol, triglycerides and insulin were performed in each individual. Subjects with obesity showed significantly higher values of HOMA (3,63 ± 1,27 vs 2,33 ± 0,52, p<0,001) as well as abdominal circumference, diastolic blood pressure, triglycerides, glucose, insulin and triglycerides/HDLcholesterol, when compared to the eutrophic subjects,. The Chi² test showed a highly significant association (p<0,001) between HOMA and MS. MS subjects had 4.7 times more risk for IR, being this finding statistically significant. To establish the correlation between variables was performed Pearson analysis demonstrating a significant correlation between HOMA and body mass index (BMI), abdominal circumference, triglycerides and triglycerides/ HDL-cholesterol. Obesity showed a high association with insulinresistance. Concluding that obesity, hypertriglyceridemia and high index triglycerides/HDL-cholesterol are high parameters for RI.
