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.

Background Tobacco advertising, promotion and sponsorship (TAPS) has been shown to increase tobacco use in both adults and young people. In Ethiopia, TAPS is recognised as a top priority for the government, and all tobacco advertising, promotion, and sponsorship forms are prohibited. There is recognition that there are gaps in the evidence needed to inform policy and practice on TAPS, but the extent and nature of these gaps have not been explored. This review was aimed at understanding the extent and nature of the evidence gaps on TAPS in Ethiopia and identifying primary research priorities to inform future research direction. Methods Systematic searches were conducted in February 2022 in the following research databases: Medline, EMBASE, and PsycInfo. Two reviewers independently screened the study reports for eligibility and extracted data from the eligible studies. The extracted data was collated and summarised descriptively and policy, practice, and research recommendations were drawn. Research topics on TAPS in Ethiopia that stakeholders perceived to be priorities for primary research were identified through a consultation workshop. Results 579 research reports were identified, and only six studies were included in the scoping review. The included studies explored the following topics: the use of tobacco imagery in movies/films (two studies); the association between mass media exposure or home internet access and tobacco use (two studies), watching of televised football and tobacco smoking in adolescents (one study), exposure to point-of-sale advertising of tobacco products and daily occurrence of smoking or second-hand smoke exposure in the home among women (one study), and exposure to anti-smoking messages through mass media and disparities in risk perceptions across socio-economic and urban-rural subgroups (one study). None of the included studies investigated tobacco-related sponsorship. The top research priority topics identified by stakeholders in Ethiopia were: 1) barriers and facilitators to TAPS policy implementation, enforcement, and compliance monitoring; and 2) developing and testing effective, low-cost, and scalable strategies for TAPS enforcement and compliance monitoring. Conclusions There is a need for research evidence to inform policy and practice on TAPS in Ethiopia, particularly on barriers and facilitators to TAPS policy implementation, enforcement, compliance monitoring, and effective, low-cost, and scalable strategies for TAPS enforcement and compliance monitoring.
