Second-Hand Tobacco Smoke Exposure and Smoke-Free Environments in Ethiopia: A Scoping Review and Narrative Synthesis.

Ethiopia passed a law prohibiting tobacco smoking in all public places in 2019. We conducted a scoping review to identify gaps in the existing literature on second-hand smoke (SHS) exposure and smoke-free environments in Ethiopia that need to be prioritised for future research to support policy and practice. We conducted systematic searches in January 2022 in the following databases: Medline, EMBASE, and PsycInfo. Two reviewers independently screened the identified study reports for eligibility and extracted data from the eligible studies. The extracted data was descriptively analysed, and research recommendations were drawn. A stakeholder consultation workshop was held to identify research topics on SHS exposure and smoke-free environments in Ethiopia that they perceived to be priorities for primary research. Of the 388 research reports identified, only nine were included in the scoping review. The topics explored includes prevalence of SHS exposure (six studies); knowledge on SHS exposure (three studies); compliance to smoke-free environments legislation (two studies); and exposure to anti-smoking messages (one study). The stakeholders prioritised further research addressing compliance monitoring and enforcement of the smoke free laws in Ethiopia. There is a need for studies that test new methods for compliance monitoring and enforcement, evaluate strategies to increase knowledge on the harms of SHS exposure and the smoke-free legislation, and evaluate the current smoke-free legislation in Ethiopia.
