Purpose: to determine the influence of climatic conditions, in particular temperature, in connection with the change of seasons, based on the results of a retrospective analysis of requests for determination of the level of glycated hemoglobin of patients in the LLC “Medical Laboratory Panakeyaˮ; to study the gender and age structure of patients with type II DM.
Materials and Methods. An analysis of information resources on the issue of the connection between changes in climatic conditions and the health status of patients with diabetes mellitus, pathogenetic mechanisms of the influence of environmental temperature on the level of glycemia was carried out, and information was collected and processed on the results of similar studies.
Results. The data of the literature review on the influence of ambient temperature on the health status of patients with DM are quite contradictory. According to the results of our analysis, the age range with the maximal number of patients with DM was 60–70 years, while the smallest number of patients was noted in the 20–30 years age range. Men significantly outnumbered women in the age group of 40–50 years and among children and adolescents, while women outnumbered men in the age groups of 20–30 years and 70 and older. Only 8.0 % of the participants had glycated hemoglobin indicators that corresponded to the normal range, while 14.0 % had indicators corresponding to the prediabetic state; the remaining 78.0 % had active diabetes. In November and December, the number of patients with elevated HbA1c decreases by 22.0 % and 26.0 %, respectively, compared to October. However, it increased significantly in January and remained at the same level throughout the spring months with a downward trend, but increases again during the summer months. Such results correspond to the data of the literature regarding the influence of temperature on the health status of patients with diabetes mellitus.
Conclusions. The maximal frequency of requests for determination of HbA1c levels in serum is noted in the age group of 60–70 years, with almost the same frequency in both men and women. In November and December, the number of patients with elevated HbA1c decreases in comparison with October, but increases in January. In the warm season, the level of HbA1c is significantly higher, which indicates a more negative effect of high temperatures on the health of the patients with diabetes.
