background: the ultimate goal of diabetes control is hba 1c improvement. the purpose of this study was to assess the effect of empowerment model on hba 1c among adolescents with type 1 diabetes. methods: the present semi-experimental study was carried out on some 47 diabetic adolescents in order to investigate the effect of an educational program based on the empowerment model on hba 1c among a...

Background and aims: Dyslipidemia is one of the major factors implicated in the development of the vascular complications of diabetes. In this study, it was evaluated the association between serum lipids profile and Hemoglobin A1c (HbA1c) in type 2 diabetes mellitus. Methods: In this cross-sectional study, the serum lipid profile and...

BACKGROUND Few studies have examined patients' views, knowledge, and understanding of glycohemoglobin A(1c) (HbA(1c)) testing. We explored such issues in patients with type 1 diabetes and used their statements to estimate analytical quality specifications for HbA(1c) testing. METHODS We recruited 201 patients from a hospital outpatient clinic. A questionnaire was used to collect information o...

OBJECTIVE To describe the distribution of HbA(1c) levels among children and young adults in the U.S. and to evaluate the effects of age, sex, race/ethnicity, socioeconomic status, parental history of diabetes, overweight, and serum glucose on HbA(1c) levels. RESEARCH DESIGN AND METHODS We analyzed HbA(1c) data from the Third National Health and Nutrition Examination Survey, 1988-1994, for 7,9...

OBJECTIVE To assess the pattern of glycosylated hemoglobin (HbA(1c)) requests by clinicians from eight health departments by calculating indicators of demand appropriateness. METHODS A cross-sectional study of the number of HbA(1c) requests by primary care clinics in 2008 and 2009. The indicator of demand appropriateness was the proportion of HbA(1c) values lower than 6.5%. Variables were col...

OBJECTIVE To compare the effects of monotherapy using nateglinide and the thiazolidinedione troglitazone with initial combination of the two agents on glycated hemoglobin (HbA(1c)) in patients with type 2 diabetes inadequately controlled by diet alone. RESEARCH DESIGN AND METHODS This study consisted of a 28-week, double-blind, randomized, multicenter study that included a 4-week, single-blin...

OBJECTIVE The A1C-Derived Average Glucose (ADAG) study demonstrated a linear relationship between HbA(1c) and mean plasma glucose (MPG). As glucose variability (GV) may contribute to glycation, we examined the association of several glucose variability indices and the MPG-HbA(1c) relationship. RESEARCH DESIGN AND METHODS Analyses included 268 patients with type 1 diabetes and 159 with type 2 ...
