Objective: (1) Describe the current literature on the relationship between EDS and SEP and (2) provide recommendations for consideration of SEP in sleep medicine and biomedical research. Methods: Databases Medline/Pubmed, Web of Science, Google scholar and Scopus were screened using PRISMA guidelines and 19 articles were included in the final synthesis. Results: All studies were cross-sectional. Among these studies, 21.05% (n = 4) are focused on children and adolescent and the lasting 88.95% (n = 15) focused on adults and old people. Age ranged between 8 and 17 years old for children/adolescent and ranged from 18 until 102 years old for adults. Main SEP measures presented in these studies were education, income, perceived socioeconomic status and employment. Sample size in these studies varied from N = 90 participants until N = 33865 participants. Overall, a lower educational level, a lower income and full-time employment were associated with EDS. EDS symptoms are prevalent in women, especially those with a low income or no job; and children and adolescents with difficult living conditions or people working part-time reported more sleep disturbances. Conclusions: SEP is already considered as an important determinant for many health outcomes, but if SEP is embedded in experimental design in psychosomatic research, biomedical research and clinical practice as a constant variable regardless of outcome; it will move forward future investigations.
