Objectives: To document the relationship between socioeconomic status (SES) and sleep health in African populations.

Methods: Observational cross-sectional or cohort studies examining the association between SES indicators and sleep outcomes in participants from African countries were included. The search was performed in the MEDLINE, Embase, and Web of Science Core Collection electronic databases in June 2021.
