Relación entre síndrome metabólico e insulino resistencia en adultos con riesgo para diabetes tipo 2

摘要

Type 2 diabetes mellitus (T2DM) is very common in the population but not always diagnosed. Alterations in the metabolism of glucose (Glu) and the metabolic syndrome (MS) are presented years before T2DM. A cross-population study, randomized and stratified by socioeconomic level in 223 subjects aged 45 and over at risk for T2DM was performed. SM was determined according to AHA / NHLBI. Objectives: a) to determine the frequency of subjects with impaired fasting Glu and SM; b) to determine the relationship between different indices of insulin resistance (IR), QUICKI, HOMA, insulin (Ins) and Ins/Glu with MS and its components. Results: elevated fasting Glu (100-125 mg/dL) was 19.3% (males 22.1%, women 17.8% (ns)), Glu≥126 mg/dL, 2.2%, SM 38.1% (males 33.8%, women 40.4% (ns)). IR was associated with waist and triglycerides (p 2.1, Ins>10 mU/L, Ins/Glu>1.8. HOMA-IR>2.1 vs MS showed: sensitivity 72.6%, specificity 70.1%, positive predictive value 60.4%, negative predictive value 80.3%. For logistic regression analysis found predictors of MS: HOMA> 2.1, OR=8.76 (95% CI 4.37-17.55), p 2.1 and QUICKI <0.33 were strong predictors of SM associated with increases in waist and triglycerides. Family history of diabetes and low levels of formal education shaped a strong predictor of SM profile.
