Evaluation of lipid peroxidation - Antioxidant protection in perimenopausal women with sleep disorders

Abstract

Objective: Our aim was to assess lipid peroxidation - antioxidant protection with the definition of the oxidative stress coefficient in perimenopausal women with sleep disorders. Methods: 45 perimenopausal women (mean age 49.1±0.32) were examined: 26 patients with sleep disorders, 19 - without sleep disorders. Evaluation of sleep disorders was conducted using a questionnaire of Stanford Centre for the Study of Sleep, test for assessment subjective severity of insomnia, the questionnaire for the quantitative assessment of the risks of sleep apnea, the scale for quantifying the degree of daytime sleepiness Epworth. We used spectrophotometric methods for lipid peroxidation - antioxidant system investigation. Statistical analysis was performed by non-parametric tests. Results: In perimenopausal women sleep disorders often presents falling asleep difficulties (93.3%) and morning awakening difficulties (78.8%). Complaints of snoring detected in 33.3% of patients. Insomnia severity index was 21.3±0.54, the total score on the Epworth scale - 12.2±0.42. The study results showed increase of secondary products of lipid peroxidation (ketodienes and coupled trienes) levels by 2.2 times (p <0.05). Coefficient oxidative stress in women with sleep disorders is higher by 2 times than in group without sleep disorders. Conclusion: In perimenopausal women sleep disorders are associated with oxidative stress, which is pathogenic rationale for inclusion in the complex therapy of these patients drugs that inhibit of lipid peroxidation activation.
