Metabolic syndrome and sleep disorders in Brazil: a short review

Abstract

Purpose: The present study analyzed the production on metabolic syndrome and sleep disorders in Brazil in the indexed scientific literature. Methods: Keywords such as “ Metabolic Syndrome”, “Cardiometabolic Risk Factors”, and “Sleep Wake Disorders” were used to find relevant research papers in PubMed and Latin American and Caribbean Literature in Health Sciences – Virtual Health Library (LILACS - VHL). Additionally, a table was built with the synthesis of the publications recovered in the two databases to characterize the publications found and an analysis of textual bodies and similarity was carried out, in order to better understand the connections between the terms that emerged from the analyzed abstracts. Results: Regarding the central theme, of the 15 publications 9 were related to the quantity and quality of sleep, focusing mostly on obstructive sleep apnea (OSA), with metabolic syndrome. In addition to these, 2 publications present the relationship between metabolic syndrome with ethnicity and chronic non-communicable diseases. And 4 publications have as their main theme sleep-related disorders only. The similarity analysis showed us that there is a relationship between the structure that circumscribes the term “sleep” with strong connective features, that is, with greater width, between the aforementioned term and the following: “metabolic syndrome”; "index"; “risk factor”, “obstructive sleep apnea – OSA” and “association”. Conclusion: This short review evidenced that the theme related to metabolic syndrome and sleep disorders in Brazil, based on the search strategies carried out, showed little literature, as well as indicating a high relationship perceived by the mathematical model of co-occurrences between the term “sleep” with “OSA”, “risk factor” and “metabolic syndrome”.
