OBJECTIVE -The aim of this study was to determine type 2 diabetes, impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) prevalence in Sivas, Turkey.
RESEARCH DESIGN AND METHODS-This cross-sectional study was conducted in the city center of Sivas. The study population of 771 subjects was selected by the cluster sampling method from 115,998 individuals aged Ն30 years. Participants with fasting venous plasma glucose concentrations Ͻ100 mg/dl were classified as "normal." Diabetes was diagnosed in participants if they had fasting blood glucose levels Ն126 mg/dl. An oral glucose tolerance test (OGTT) was performed in subjects with fasting blood glucose levels Ն100 mg/dl and Ͻ126 mg/dl.RESULTS -According to the fasting blood glucose levels of the 771 subjects, 44 (5.7%) had diabetes. OGTTs were performed in 80 (10.4%) subjects. According to OGTT results, there were 5 subjects with diabetes, 20 subjects with IGT (2.6%), and 55 subjects with IFG (7.1%). The combined prevalence of IFG and IGT was 9.7%. After OGTT, the total number of diabetic subjects was determined to be 49 (6.4%). Twenty-four (3.1%) of the subjects had a previous diagnosis of diabetes. Multivariate analyses showed that age, sex, hypertension, cigarette smoking, obesity, and family history of diabetes were risk factors for type 2 diabetes (P Ͻ 0.05).
CONCLUSIONS -Diabetes incidence increases with changes in dietary habits and lifestyle.Education is particularly important for public health, as the community may then have required knowledge about the disease and its risk factors.
Diabetes Care 28:795-798, 2005T ype 2 diabetes is recognized as a major global health problem, and its prevalence is increasing. The number of adults with diabetes is roughly estimated to be 135 million worldwide (1).Turkey resembles a bridge in geographical aspects between Europe and Asia. This study was conducted in Sivas, Turkey, which is the largest city of Central Anatolia in terms of surface area. In this region, immigration to the city center from rural parts of the territory is still an ongoing event. Economical improvements and urbanization cause major changes in lifestyles and dietary habits. Consumption of carbohydrates and fat is also frequent in this area.Previous studies reported diabetes prevalence of 1.0 and 1.5%, respectively, in Turkey's rural areas (2,3) and 4.5, 6.3, 6.9, and 6.0%, respectively, in Turkey's urban areas (4 -7).RESEARCH DESIGN AND METHODS -We conducted this cross-sectional study in the city center of Sivas between November 2003 and February 2004. The study population of 773 subjects was selected by cluster sampling method among 115,998 individuals aged 30 years. We were able to contact 771 subjects (␣ ϭ 0.05, d ϭ 0.03, P ϭ 0.05, q ϭ 0.95, n ϭ 115,998), and we interviewed these individuals face to face. Participants were informed of the purpose of the study and the test; a patient information sheet that included a brief outline of the reason for the test and the procedure to be used was provided at least 3 days before the test.
