BACKGROUND: The World Health Organization considers diabetes mellitus as a significant public health problem, including this disease as one of the four priority noncommunicable diseases. Over the past few decades, the prevalence of diabetes has been steadily increasing and represents a significant threat to the public health of the world’s population. In connection with the territorial features of residence and the availability of medical care to residents of urban and rural areas, studies that include an analysis of the incidence of diabetes mellitus, disability and mortality of the urban and rural population from complications of this disease are one of the important mechanisms for monitoring the health status of the population, which predetermines the improvement and implementation strategies aimed at improving the demographic situation.

AIM: To conduct a comparative retrospective analysis of the health indicators of patients with type 1 and type 2 diabetes mellitus living in urban and rural areas of the Saratov region.

MATERIALS AND METHODS: Information on life expectancy, morbidity, complications, causes of disability, direct causes of death in patients with type 1 and type 2 diabetes mellitus living in the Saratov region in urban and rural areas was obtained from the Federal Register of Patients with Diabetes; information on the urban and rural population of the Saratov region was obtained from official statistical sources published on the website of the Federal State Statistics Service. Mathematical, statistical and analytical research methods were used. Statistical data processing was carried out using the Microsoft Excel 2019 program. The significance of the difference between the average and relative values was assessed using the Student’s t-test. The presence of a relationship between the signs was determined using the Pearson coefficient. The Mann-Whitney U-test was used to compare populations by quantitative characteristics. The significance level was determined at t>2 and p<005. Data were presented as P ± m, where P is the relative value and m is its standard error, and M ± m, where M is the mean value and m is its standard error.

RESULTS: A higher average life expectancy was noted for people with type 2 diabetes, regardless of place of residence, in comparison with the same indicator in the Saratov region. The average life expectancy of patients with type 1 diabetes is 18 years lower than in the Saratov region for those living in urban areas and 17 years for rural residents. There is an excess of the levels of primary and general morbidity in people suffering from type 1 and 2 diabetes and living in rural areas over the same indicators of urban residents. The main causes of death in both urban and rural patients with type 1 and 2 diabetes are: chronic cardiovascular insufficiency, cerebrovascular accident and acute cardiovascular diseases. Disability rates in patients with type 2 diabetes living in urban areas are lower than in rural areas.

CONCLUSION: Analysis of data from the Federal Register of Patients with Diabetes Mellitus in the Saratov Region showed high levels of primary and general morbidity, disability and mortality in patients with type 1 and 2 diabetes living in rural areas. Also, frequently occurring complications from the cardiovascular system were identified in all patients with type 1 and type 2 diabetes, regardless of the place of residence. The relationship between the levels of morbidity, mortality, disability, the incidence of complications and the place of residence of patients with type 1 and type 2 diabetes is not statistically significant.
