OBJECTIVE To examine the magnitude and types of hospitalizations among persons with prediabetes, undiagnosed diabetes, and diagnosed diabetes. RESEARCH DESIGN AND METHODS This study included 13,522 participants in the Atherosclerosis Risk in Communities (ARIC) study (mean age 57 years, 56% female, 24% black, 18% with prediabetes, 4% with undiagnosed diabetes, 9% with diagnosed diabetes) with ...

BACKGROUND To estimate the prevalence of diagnosed and undiagnosed diabetes mellitus, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and combined IFG/IGT in a large urban Iranian population aged > or = 20 years. METHODS The study population included 9,489 participants of the Tehran Lipid and Glucose Study with full relevant clinical data. Age-standardized prevalence of diab...

BACKGROUND The Achutha Menon Centre Diabetes Risk Score (AMCDRS), which was developed in rural Kerala State, South India, had not previously been externally validated. We examined the performance of the AMCDRS in urban and rural areas in the district of Vellore in the South Indian state of Tamil Nadu, and compared it with other diabetes risk scores developed from India. METHODS We used the da...

OBJECTIVE We examined the prevalences of diagnosed diabetes, and undiagnosed diabetes and pre-diabetes using fasting and 2-h oral glucose tolerance test values, in the U.S. during 2005-2006. We then compared the prevalences of these conditions with those in 1988-1994. RESEARCH DESIGN AND METHODS In 2005-2006, the National Health and Nutrition Examination Survey included a probability sample o...

OBJECTIVE Health administrative data are frequently used for diabetes surveillance, but validation studies are limited, and undiagnosed diabetes has not been considered in previous studies. We compared the test properties of an administrative definition with self-reported diabetes and estimated prevalence of undiagnosed diabetes by measuring glucose levels in mailed-in capillary blood samples. ...

This was a cross-sectional study designed to assess the validity of the Finnish Diabetes Risk Score for detecting undiagnosed type 2 diabetes among general medical outpatients in Botswana. Participants aged ≥20 years without previously diagnosed diabetes were screened by (1) an 8-item Finnish diabetes risk assessment questionnaire and (2) Haemoglobin A1c test. Data from 291 participants were an...

The aim of this study was to obtain an accurate estimate of diabetes prevalence in Croatia and additional estimates of impaired fasting glucose (IFG), undiagnosed diabetes and insulin resistance. The study was part of the First Croatian Health Project. Field work included a questionnaire, anthropological measurements and blood sampling. A nationally representative sample of 1,653 subjects aged ...

OBJECTIVE To assess, in an older population, the prevalence of diagnosed and undiagnosed diabetes, the number needed to screen (NNTS) to identify one individual with undiagnosed diabetes, and factors associated with undiagnosed diabetes. RESEARCH DESIGN AND METHODS Socioeconomic and health-related factors were assessed at the baseline examination of the Health, Aging, and Body Composition (He...

OBJECTIVE To evaluate A1C for screening and diagnosis of undiagnosed type 2 diabetes defined by oral glucose tolerance testing in clinical and general populations. RESEARCH DESIGN AND METHODS A1C cut offs (< or =5.5% to rule out diabetes; > or =7.0% to rule in diabetes) were derived from a clinical group (Melbourne Pathology [MP] group: n = 2,494; undiagnosed diabetes 34.6%) and then evaluate...

We aimed to assess clinical and socio-demographic characteristics of undiagnosed diabetes, including glucose control, in French community-living elderly people. Diagnosed and undiagnosed diabetes, impaired fasting glucose (IFG) and characteristics of subjects were assessed by interview, clinical examination and fasting blood glucose measures at the baseline visit of the Three-City (3C) study in...
