OBJECTIVE Discordance between HbA(1c) and fructosamine estimations in the assessment of glycemia is often encountered. A number of mechanisms might explain such discordance, but whether it is consistent is uncertain. This study aims to coanalyze paired glycosylated hemoglobin (HbA(1c))-fructosamine estimations by using fructosamine to determine a predicted HbA(1c), to calculate a glycation gap ...

OBJECTIVE To determine the relationship between mean sensor glucose concentrations and hemoglobin A(1c) (HbA(1c)) values measured in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications laboratory at the University of Minnesota in a cohort of subjects with type 1 diabetes from the Juvenile Diabetes Research Foundation continuous glucose monitorin...

BACKGROUND Patient education is a cornerstone of treatment in diabetes mellitus, but there is not unanimity of opinion as to how it should be delivered. OBJECTIVE To determine whether a single, intensive group educational program would improve glycosylated hemoglobin (HbA(1c)) levels when compared with passive education. METHODS A total of 106 patients with HbA(1c) levels greater than 8.5% ...

In the general population, hyperglycemia in the absence of diabetes may be associated with increased risk for mortality. Hyperglycemia is prevalent in chronic kidney disease; however, the relationship between glycosylated hemoglobin (HbA(1c)) as a marker of chronic hyperglycemia and outcomes has not been studied in nondiabetic chronic kidney disease. HbA(1c) was measured at baseline in the rand...

BACKGROUND Type 2 diabetes is common, largely managed in primary care and requires effective glycaemic control to reduce the risk of microvascular complications. Oral hypoglycaemic agents are typically the first pharmacological intervention used to improve glycaemic control. OBJECTIVES To evaluate the management of people with type 2 diabetes with oral hypoglycaemic agents in primary care. ...

AIMS/HYPOTHESIS To analyze the relationship between glucose and glycated hemoglobin (HbA(1c)) in the adult Galician population, evaluate the use of HbA(1c) for the screening and diagnosis of diabetes, and calculate the diagnostic threshold required for this purpose. METHODS We analyzed data on 2848 subjects (aged 18-85 years) drawn from a study undertaken in 2004 to assess the prevalence of d...

OBJECTIVE Safety and efficacy of biphasic insulin aspart 70/30 (BIAsp 70/30, prebreakfast and presupper) were compared with once-daily insulin glargine in type 2 diabetic subjects inadequately controlled on oral antidiabetic drugs (OADs). RESEARCH DESIGN AND METHODS This 28-week parallel-group study randomized 233 insulin-naive patients with HbA(1c) values >/=8.0% on >1,000 mg/day metformin a...

OBJECTIVE To assess the validity of self-report measures of diabetes medication adherence and evaluate the effect of depression on the validity of these reports. RESEARCH DESIGN AND METHODS Adults with type 2 diabetes, treated with oral medications, completed a set of medication adherence self-reports that varied response scales and time frames, were administered structured clinical interview...

OBJECTIVE To assess change in health-related quality of life (HRQOL) in children with diabetes over 2 years and determine its relationship to change in metabolic control. RESEARCH DESIGN AND METHODS In 1998, parents of children aged 5-18 years attending a tertiary diabetes clinic reported their child's HRQOL using the Child Health Questionnaire PF-50. Those aged 12-18 years also self-reported...

OBJECTIVE To examine the influence of glycemic and nonglycemic parameters on HbA(1c) concentrations in young adults, the majority of whom had normal glucose tolerance. RESEARCH DESIGN AND METHODS We compared the diagnosis of normal glucose tolerance, prediabetes, and diabetes between a standard oral glucose tolerance test (OGTT; World Health Organization 2006 criteria) and HbA(1c) concentrati...
