HYPERTENSIVE DISORDERS IN PREGNANT WOMEN SUBJECT TO THE CLIMATE CHANGE
Department of Obstetrics and Gynecology № 1, Avicenna Tajik State Medical University, Dushanbe, Republic of Tajikistan
Based on the analysis of the world literature, it turned out that climate change in the direction of warming worsens pregnancy and perinatal outcomes. However, the results of numerous studies conducted in different parts of the world to study the correlation between ambient temperature, relative humidity and intensity of sunlight, as well as the frequency of hypertensive disorders during pregnancy, are contradictory. Despite differences in results, a tendency to a higher incidence of preeclampsia is observed during the cold months. An explanation in support of this theory would be that more low temperatures affect the incidence of preeclampsia and eclampsia, increasing the vasospasm inherent in the disease. Recognizing the exact relationship with different weather conditions can help you understand what factors may be involved in the launch of these processes. These studies are particularly relevant in the conditions of Tajikistan, where the mass of extragenital diseases present in pregnant women in the region is also joined by the climate warming factor.
