“…Although no scores related to sleep was extracted for our study, two articles were rated by EES [14,17], and one group was rated by PSQI [10]. Several studies showed that the non-RLS group slept better than RLS group [13,15,16]. Our ndings supported the idea that the most important cause of MDD might be chronic insomnia caused by RLS.…”
A significant association between major depressive disorder (MDD) and restless legs syndrome (RLS), but RLS prevalence is dramatically different among MDD individuals across studies. Our present work aimed to comprehensively evaluate available evidences to determine the role of RLS in MDD. PubMed, Web of Science, Embase, Science Online, Wip Chinese Biomedical Journal, Wanfang and Chinese National Knowledge Infrastructure were searched to identify observational and case-control studies relevant to RLS and MDD. Stata 12.0 software was used for meta-analysis. RLS individuals exhibited a higher risk of MDD than non-RLS controls (OR 2.05, 95%CI 1.80–2.33; p<0.05). No significant differences were found in MDD prevalence between young RLS patients (OR 2.10, 95%CI 1.72–2.56) and older RLS patients (OR 2.02, 95%CI 1.70–2.39). In addition, no significant difference in MDD prevalence was evident between between Asian (OR 1.98, 95%CI 1.66–2.37) and European or American (OR 1.76, 95%CI 1.54–2.01) RLS patients. Our meta-analysis provides evidence that the risk for MDD is higher among RLS patients compared to non-RLS individuals suggesting that RLS may play an important role in MDD patheogenesis.

“…In a study performed in Kayseri in Turkey, 665 cognitively intact older participants (aged ≥60 years) were evaluated and the prevalence of RLS was estimated %15.8 according to the criteria of International RLS group. RLS was significantly associated with impaired self-reported sleep quality and difficulty in falling asleep (25). Prevalence of RLS varies due to population characteristics and assessment method; either a single question or criteria.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
