Sleep disorders and effectiveness of various methods of insomnia therapy in pregnant women (Literature review)

Abstract

Sleep disorders (dyssomnia) during pregnancy are of high prevalence and may be associated with negative peri- and postnatal outcomes. However, these conditions are often not effectively diagnosed and treated. In this review a systematic evaluation of the effectiveness of different methods of therapy to improve the quality of sleep and in the presence of insomnia during pregnancy was conducted.Systematic search in PubMed, Psycinfo and Medline databases was conducted without limiting the publication date till November 3, 2022. The relevant studies included pregnant women of any age and gestation; they included the clinical intervention schemes aimed at improving sleep quality; the data before and after treatment for one or more sleep-related results were reported. 16 studies were selected with a total of 988 pregnant women. According to the results of researches the effectiveness of different types of interventions was established: cognitive-behavioral therapy for sleep disorders, pharmacotherapy, acupuncture, yoga, relaxation and phytotherapy. The recent publications have determined that sleep disorders have a connection with the adverse pregnancy outcomes, including fetal growth restriction, premature births, weakness of uterine labor activity and high delivery frequency of caesarean section.There is an extremely high relevance and need for high-quality randomized controlled studies about sleep disorders during pregnancy and implementation of effective standard obstetric care programs. There is a necessity to improve psychological care and sleep care during pregnancy to maintain a positive pregnancy course, childbirth and postpartum period. Future clinical studies should be randomized and include a sufficient number of women for statistical efficacy, including checking the effectiveness of cognitive-behavioral insomnia therapy to prevent pregnancy/childbirth complications and somatic diseases in the long-term period.
