Promising directions of medical technologies for the correction of sleep disorders in menopausal women of various ethnic groups

ethnic groups. Materials and methods.The objects of the study were menopausal women of Russian and Buryat ethnic groups (n=466), who were divided into a control group (without sleep disturbances) and main subgroups (with insomnia and comorbidity of insomnia with obstructive sleep apnea syndrome). All women underwent clinical and anamnestic examination, genotyping for3111T/C Clock gene polymorphism, determination of the circadian profile of melatonin secretion, parameters of lipid metabolism and the system lipid peroxidation antioxidant protection. Results.In Caucasians with sleep disorders, a higher prevalence of the3111T/T genotype and theClockgene3111Tallele was revealed as compared to the control (p0.05). Perimenopausal Caucasians showed a shift in the peak of melatonin secretion to the morning hours; in Mongoloids, both peri- and postmenopausal women, a decrease in melatonin total levels was revealed. Dyslipoproteinemia is characteristic of both races patients who have comorbidity of insomnia and obstructive sleep apnea syndrome, and it is more pronounced in postmenopausal Caucasians. Oxidative stress in sleep disorders is more pronounced in Mongoloids. The medical technologies directions for correction of sleep disorders are proposed: the use of melatonin drugs in the evening and light therapy in the early morning hours in Caucasians who are carriers of the3111T Clockgene allele; melatonin drugs to increase its total level in Mongoloids; personalized prescription of antioxidant therapy in all patients; specific therapy to eliminate breathing disorders during sleep in those who have obstructive sleep apnea syndrome. Conclusions.Presence of insomnia, chronobiological rhythms of melatonin secretion, lipid peroxidation processes in sleep disorders are ethnospecific.
