Abstract
INTRODUCTION. Active searching for patients with carbohydrate metabolism
disorders is the best method for preventing of chronic complications of the disease.
The aim of the study was to find risk factors and to estimate prevalence of type
2 diabetes (known and unknown) in Wrocław population.
MATERIAL AND METHODS. The study was entered by subjects aged 55-75 years who were randomly chosen (the random number method) from the Wrocław population PESEL database. The first stage consisted of: age, profession, life-style questionnaire, family history, suffered diseases before and the anthropometrical evaluation, blood pressure and fasting capillary glucose level were performed. The patients with incorrect glucose level were included to second stage where fast glucose level and OGTT above 5.5-6.7 mmol/l evaluated.
RESULTS. To second stage study 362 (216 women and 146 men) from 1500 subject were included with glycaemia higher than 5.5 mmol/l. The known diabetes was found in 72 persons (19.8%). The diagnosis of diabetes was confirmed because of two examination results higher than 7 mmol/l. Based on OGTT in 21.37% of patients diabetes and in 37.24% impaired glucose tolerance.
CONCLUSIONS. Between 55-65 aged patients the prevalence of unknown diabetes was higher than known diabetes while known diabetes in patients older than 65 years was more common. Unknown diabetes was found significantly more often in females. In female with unknown and known diabetes BMI was not significantly different.
