HOMA1-IR and HOMA2-IR indexes in identifying insulin resistance and metabolic syndrome: Brazilian Metabolic Syndrome Study (BRAMS)

Abstract: Objective: To investigate cut-off values for HOMA1-IR and HOMA2-IR to identify insulin resistance (IR) and metabolic syndrome (MS), and to assess the association of the indexes with components of the MS. Methods: Nondiabetic subjects from the Brazilian Metabolic Syndrome Study were studied (n = 1,203, 18 to 78 years). The cut-off values for IR were determined from the 90 th percentile in the healthy group (n = 297) and, for MS, a ROC curve was generated for the total sample. Results: In the healthy group, HOMA… Show more

“…In a 2009 Brazilian study, Geloneze and cols. analyzed 1,203 patients without diabetes and without HCV infection (35). They reported a HOMA-IR cutoff point of 2.7 for IR diagnosis, which is close to the level we used in our study.…”

“…The HOMA-IR (homeostasis model assessment -insulin resistance) was calculated according to the formula proposed by Matthews et al 15 . Insulin resistance was defined as HOMA-IR > 2.7 6 .…”

“…An alternative to the evaluation of IR is the homeostatic model assessment index of insulin resistance (HOMA-IR), is a validated method which predicts insulin sensitivity by simple measurements of fasting blood glucose and insulin, is easier to apply and has a strong correlation with the clamp method. HOMA-IR is a suitable method for large-scale studies 6 . Anthropometric and body composition indicators are alternative instruments to evaluate IR in an accessible, fast and noninvasive manner 5 .…”

“…Foram definidos os grupamentos ponderais de acordo com o IMC: normal (18,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)9), sobrepeso (25-30) e obesidade (>30). A pressão arterial (mmHg) foi mensurada no braço direito, com a paciente sentada, após cerca de dez minutos em repouso.…”

“…Nesse intervalo também foi efetuado o exame ultrassonográfico, pelo que a exploração privilegiou a densidade do estroma ovariano, ampliado e luzente (plano transversal) e a localização periférica ou disseminada dos folículos 13 . De modo a refletir a sensibilidade à insulina, foi utilizado o homeostatic model assessment of insulin resistance (HOMA-IR) -modelo matemático de aferição da resistência insulínica -por intermédio do HOMA Calculator 14 , com ponto de corte ≥1,8 15 . As análises se cumpriram, além das dosagens de glicose e insulina, acrescidas do teste oral de tolerância à glicose (TOTG, 75 g) 16 .…”
