Restless legs syndrome in pregnancy: A systematic review of prevalence

Restless legs syndrome is a neurological disease from the spectrum of movement disorders, with psychiatric comorbid symptoms and manifestations. Women are affected twice as often as men, and the frequency in the population is 4-10%, while during pregnancy the prevalence triples. This research was conducted as a result of a search and selection of studies on the prevalence of RLS in pregnancy, which include works published in domestic and foreign journals and searches of PubMed, PubMed Central, Web of Science, Scopus and Embase. A primary search of medical databases found 316 publications. In this secondary process, due to the lack of access to the abstract or full text, and due to the poor quality of the articles, 11 relevant publications were finally found and included in this systematic review. The total number of respondents included in this research is 7033, aged 19-45. The lowest prevalence was 4.9% in Japan, and the highest prevalence was 54.7% in Saudi Arabia. In this review, the overall mean frequency of restless legs syndrome during pregnancy was 24.69%. Furthermore, in our ongoing research conducted in 2022 on restless legs syndrome, we recorded a frequency of 26.5% in a population of 266 pregnant women in the third trimester of pregnancy. The frequency of restless legs syndrome is high among the population of pregnant women, and according to its etiology, clinical manifestations and comorbid manifestation, this disorder represents a close link between psychiatry, neurology and gynecology. For this reason, pregnant women should pay extra attention to the early detection of this disorder, which can significantly affect a pregnant woman's daily energy level, poor sleep and daytime sleepiness, and more frequent symptoms of anxiety and depression.
