The prevalence of prediabetic state (impaired fasting glucose(IFG) and/or impaired glucose tolerance (IGT)) and type 2 diabetes is still increasing and nowadays reaches the size of epidemic. Moreover, diagnosis of type 2 diabetes is often overtaken by the appearance of late diabetic complications. The aim of the study was to evaluate the prevalence of prediabetes and type 2 diabetes in inhabitants of Warsaw and the province of Mazovia, situated in the centre of Poland, who were over 45 years of age and/or presented type 2 diabetes risk factors. The additional aim of the study was to estimate the presence of late complications in patients with newly diagnosed type 2 diabetes. In order to National Programme for Diabetes Prevention and Education for year 2012, 1510 citizens of Warsaw and Mazovia province were examined. In each subject with newly diagnosed impaired fasting glucose (IFG) an oral glucose tolerance test (OGTT) was conducted. Each person with newly diagnosed type 2 diabetes, afterwards was a subject of the set of examinations including: ECG, USG of lower extremities arteries, ophtalmoscopy, neurological consultation (verification of touch, pain, temperature and vibration sensation) and biochemical tests (HbA1c, total cholesterol, triglicerides, creatinine and urine albumin concentration). We diagnosed type 2 diabetes in 121 subjects and prediabetes in 337 individuals (8.01% and 22.3% of participants, respectively). In newly diagnosed type 2 diabetics macroangiopathy was present in 11.58% of patients, diabetic retinopathy in 10.74 %, whereas the largest percentage of patients (19%) presented diabetic neuropathy.
