OBJECTIVE To compare the 1999 World Health Organization (WHO) fasting plasma glucose (FPG) criteria and the WHO 2-hour post-challenge glucose (2hPG) criteria during an oral glucose tolerance test (OGTT) in identifying adults in Jamaica with hyperglycemia. As the OGTT is not commonly used in clinical practice, factors associated with the failure of the FPG criteria to detect persons with impaire...

The reported glucose and immunoreactive insulin (IRI) responses to oral and intravenous glucose in subjects with Type 2 diabetes have not always been consistent. This may have resulted from variations in the method of glucose administration, the ethnic backgrounds of subjects, the diagnostic criteria applied, the duration of the disease or IRI assay methods. The use of a mixed meal rather than ...

OBJECTIVE Our objectives were to determine the prevalence of previously undiagnosed abnormal glucose tolerance, i.e., diabetes and impaired glucose tolerance (IGT) in patients with acute coronary syndrome and to assess the utility of admission and fasting glucose in identifying diabetes in these patients. RESEARCH DESIGN AND METHODS Glycemic status was characterized on the basis of admission ...

OBJECTIVE Persons with diabetes have accelerated muscle loss. The association of fasting and postchallenge glucose levels per se to grip strength, a clinical marker of poor physical function, and potential sex differences in this relationship has not been previously described. DESIGN Longitudinal cohort. SETTING USA. PARTICIPANTS Participants were community-dwelling older adults (mean age...

OBJECTIVE To study the effects of losartan and atenolol on glucometabolic parameters in nondiabetic hypertensive patients. MATERIALS AND METHODS In a prospective, open-label, parallel group study, nondiabetic patients with mild to moderate hypertension were randomized to either losartan (titrated from 50 to 100 mg/day, n = 20) or atenolol (titrated from 25 mg to 100 mg/day, n = 20) for period...

The contribution of gluconeogenesis (GNG) to endogenous glucose output (EGO) in type 2 diabetes is controversial. Little information is available on the separate influence of obesity on GNG. We measured percent GNG (by the 2H2O technique) and EGO (by 6,6-[2H]glucose) in 37 type 2 diabetic subjects (9 lean and 28 obese, mean fasting plasma glucose [FPG] 8.3 +/- 0.3 mmol/l) and 18 control subject...

OBJECTIVE To report the age- and sex-specific prevalences of diabetes and impaired glucose regulation (IGR) according to the revised 1999 World Health Organization criteria for diabetes in Europe. RESEARCH DESIGN AND METHODS A total of 13 studies from nine European countries with 7,680 men and 9,251 women aged 30-89 years were included in the data analysis. RESULTS In most of the study popu...

Left ventricular (LV) hypertrophy and LV diastolic dysfunction are common cardiac changes in hypertensive patients, and these changes are modified by various factors other than blood pressure. The present study was conducted to investigate the influence of mild abnormalities in glucose metabolism on LV structure and function in essential hypertension. In 193 nondiabetic patients with treated es...

AIMS/INTRODUCTION The conventional oral glucose tolerance test (OGTT) cannot detect future diabetics among isolated impaired fasting glucose (is-IFG) nor normal glucose tolerant (NGT) groups. By analyzing the relationship between fasting (FPG) and 2-h plasma glucose (2hPG), the present study identifies is-IFG subjects liable to worsening glucose homeostasis. MATERIALS AND METHODS Oral glucose...

We aimed to investigate associations of the dietary inflammatory index (DII) with glucose-insulin homeostasis markers, and the risk of glucose intolerance. This cross-sectional study included 2975 adults from the Tehran Lipid and Glucose Study. Fasting plasma glucose (FPG), 2-h post-load glucose (2h-PG), and fasting serum insulin were measured. Homeostatic model assessment of insulin resistance...
