COVID-19-related global health governance and population health priorities for health equity in G20 countries: a scoping review.

Since the declaration of the COVID-19 pandemic, the promotion of health equity including the health of various population sub-groups has been compromised, human rights jeopardised, and social inequities further exacerbated. Citizens worldwide, including in the Group of 20 (G20) countries, were affected by both global health governance (GHG) processes and decisions and public health measures taken by governments to respond to COVID-19. While it is critical to swiftly respond to COVID-19, little is known about how and to what extent the GHG is affecting population health priorities for health equity in global economies such as the G20 countries. This scoping review synthesised and identified knowledge gaps on how the COVID-19-related GHG is affecting population health priorities for policy, programme, and research in G20 countries. We followed the five-stage scoping review methodology promoted by Arksey and O'Malley and the PRISMA Extension for Scoping Reviews guidelines. We searched four bibliographic databases for references conducted in G20 countries and regions and published in English and French, between January 2020 and April 2023. Out of 4,625 references and after two phases of screening, 14 studies met the inclusion criteria. G20 countries included in the review were Australia, Brazil, Canada, China, France, India, Italy, Japan, Russia, South Africa, the United Kingdom, the United States of America, and the European Union. We found insufficient collaboration and coordination and misalignment among governance actors at multiple levels. In most cases, equity considerations were not prioritised while unequal consequences of COVID-19 public health measures on population groups were widely reported. COVID-19-related population health priorities mainly focused on upstream and midstream determinants of health. Our scoping review showed the stark inequities of COVID-19 public health outcomes, coupled with a prevalent lack of coherent collaboration and coordination among governance actors. Moreover, governance as an object of empirical study is still emerging when examining its intersection with global health and population health policy, programme, and research. An urgent shift is required to effectively act upon structural health determinants that include transformative and comprehensive policies for prevention, equity, resilience, and sustainable health.
