OBJECTIVE Insulin resistance (IR) in older individuals is associated with risk factors for coronary artery disease. The glucose clamp measures IR directly, but the homeostasis model assessment (HOMA) of IR, referred to here as HOMA-IR, is based on fasting glucose and insulin and is less invasive and labor intensive. This method requires validation in the elderly. RESEARCH DESIGN AND METHODS W...

BACKGROUND Polycystic ovary syndrome (PCOS) represents a moving spectrum of hormonal to metabolic abnormalities, as women with the syndrome are aging. Hormonal abnormalities, anovulation, and hyperandrogenic signs were predominant during the early years of PCOS and fade away with the years. Metabolic abnormalities and insulin resistance (IR) remain throughout the PCOS life cycle; however, it is...

Increased insulin resistance is a therapeutic target in patients with chronic liver disease. Branched-chain amino acids (BCAA) have been reported to improve insulin resistance in in vivo experiments. Thus, we investigated the effects of BCAA on insulin resistance in patients with chronic liver disease. Twelve patients with chronic liver disease were enrolled. Each patient was given one sachet o...

La obesidad infantil contribuye a la presencia de Resistencia Insulina (IR), lo que su vez incrementa el riesgo padecer alteraciones endocrino-metabólicas en niñez. El HOMA-IR ha demostrado tener gran utilidad para detección y seguimiento estas patologías, sin embargo, se deben considerar las variables fisiológicas patológicas está sujeto cálculo. Además tiene una buena correlación con clamp eu...

BACKGROUND Recent studies have demonstrated that low and high birth-weight at birth are risk factors of developing diabetes. The aim of this study was to determine if the abnormal birth-weight is related with hyperinsulinemia and elevated index of the Homeostasis Model assessment for Insulin Resistance (HOMA-IR) at birth, in at term newborns. METHODS Newborns with gestational age between 38 a...

Purpose: Insulin resistance (IR) plays an important role in the pathogenesis of polycystic ovary syndrome (PCOS); therefore, insulin-sensitizing agents are widely used to improve IR in women with PCOS. However, whether IR in patients without PCOS should be treated remains uncertain. This study aims to clarify whether IR in patients without PCOS affects the outcomes of in-vitro fertilization-emb...

The aim of this study was to measure insulin resistance (IR) in dialysis patients and its relation to Vitamin D status and nutritional parameters. We included patients on maintenance dialysis, both hemodialysis and peritoneal dialysis (HD and PD). IR was measured by homeostatic model assessment (HOMA)-IR index defined as fasting serum insulin (μU/L) × fasting blood sugar (mmol/L)/22.5. Baseline...

BACKGROUND Studies exploring the association between insulin resistance (IR) and cardiovascular disease in blacks have not been conclusive, especially for coronary heart disease (CHD). The McAuley index and homeostasis model assessment of IR (HOMA-IR) perform differently in predicting cardiovascular disease. We investigated this association in the Jackson Heart Study, a large longitudinal cohor...

Objective: There is an increased risk of coronary artery disease (CAD) in both diabetes and non-diabetes. Insulin resistance (IR) has been associated with the development of CAD in this both populations. However, there are not many studies on correlation between IR and severity of CAD in nondiabetes. This study aimed to establish a correlation between IR and severity of CAD in non-diabetic indi...

BACKGROUND Whether insulin resistance predicts ischemic stroke (IS) is still a matter of debate. OBJECTIVE To determine the association between insulin resistance (IR) and risk of first ischemic stroke in a large, multiethnic, stroke-free cohort without diabetes. DESIGN Prospective, population-based cohort study. SETTING Longitudinal epidemiologic study. PARTICIPANTS A cohort of 1509 no...
