BackgroundGovernments can intervene to change health-related behaviours using various measures but are sensitive to public attitudes towards such interventions. This review describes public attitudes towards a range of policy interventions aimed at changing tobacco and alcohol use, diet, and physical activity, and the extent to which these attitudes vary with characteristics of (a) the targeted behaviour (b) the intervention and (c) the respondents.MethodsWe searched electronic databases and conducted a narrative synthesis of empirical studies that reported public attitudes in Europe, North America, Australia and New Zealand towards interventions relating to tobacco, alcohol, diet and physical activity. Two hundred studies met the inclusion criteria.ResultsOver half the studies (105/200, 53%) were conducted in North America, with the most common interventions relating to tobacco control (110/200, 55%), followed by alcohol (42/200, 21%), diet-related interventions (18/200, 9%), interventions targeting both diet and physical activity (18/200, 9%), and physical activity alone (3/200, 2%). Most studies used survey-based methods (160/200, 80%), and only ten used experimental designs.Acceptability varied as a function of: (a) the targeted behaviour, with more support observed for smoking-related interventions; (b) the type of intervention, with less intrusive interventions, those already implemented, and those targeting children and young people attracting most support; and (c) the characteristics of respondents, with support being highest in those not engaging in the targeted behaviour, and with women and older respondents being more likely to endorse more restrictive measures.ConclusionsPublic acceptability of government interventions to change behaviour is greatest for the least intrusive interventions, which are often the least effective, and for interventions targeting the behaviour of others, rather than the respondent him or herself. Experimental studies are needed to assess how the presentation of the problem and the benefits of intervention might increase acceptability for those interventions which are more effective but currently less acceptable.

Networked models are often proposed as a means to enhance health research capacity‐building in Africa. This paper addresses a knowledge gap on what works and does not in capacity‐building in African research settings. It provides an analysis of how multi‐partner networks are built and how their success depends on building institutional level capacity‐strengthening within partner institutions. To do this, the paper focuses on the Wellcome Trust's African Institutions initiative, drawing on initial learning and evaluation project data. We identify priority areas for policy attention and share emerging early insights on mechanisms and strategies being implemented by consortia to address key challenges.

The digital transformations taking place across the African continent present an urgent need for fresh thinking in the study of publics. This introduction lays out the impetus and contribution of this Special Issue to such a rethinking of the study of publics in Africa. Following in the footsteps of a wider body of scholarship, we draw on Africa's pasts and present in order to move beyond the limiting assumptions, histories and languages that are embedded within Western scholarship on publics. We make the case that both de-Westernising and capturing publics in a digital age in Africa require openness to a diversity of disciplines, approaches and questions. In addition, we explain how, collectively and individually, the articles in this Special Issue contribute to taking up this task. Taken together, the articles are an eye-opening collection on the unfolding practices of citizens convening and participating in discussions using both newer and older media and communication platforms across Somalia,

This article presents new empirical insights into what people do with conspiracy theories during crises. By suppressing the impulse to distinguish between truth and falsehood, which has characterized most scholarship on the COVID-19 “infodemic,” and engaging with claims surrounding two popular COVID-19 conspiracies—on 5G and on Bill Gates—in South Africa and Nigeria, we illustrate how conspiracies morph as they interact with different socio-political contexts. Drawing on a mixed-method analysis of more than 6 million tweets, we examine how, in each country, conspiracies have uniquely intersected with longer-term discourses and political projects. In Nigeria, the two conspiracies were both seized as opportunities to extend criticism to the ruling party. In South Africa, they produced distinctive responses: while the 5G conspiracy had limited buy-in, the Gates conspiracy resonated with deep-rooted resentment toward the West, corporate interests, and what is seen as a paternalistic attitude of some external actors toward Africa. These findings stress the importance of taking conspiracy theories seriously, rather than dismissing them simply as negative externalities of digital ecosystems. Situating conspiracies in specific dynamics of trust and mistrust can make an important difference when designing responses that are not limited to broadcasting truthful information, but can also enable interventions that account for deeply rooted sentiments of suspicion toward specific issues and actors, which can vary significantly across communities.
