BACKGROUND:
Commercial actors, such as alcohol and ultra-processed food producers markedly determine global health outcomes. Understanding their colonial antecedents and afterlives through innovative empirical research is an important approach for decolonising global health. This organised session introduces and provides opportunities to apply methods for considering coloniality in commercial determinants of health (CoDH) research.

METHODS:
Three novel methods, adapted from prior experience and informed by coloniality theory, for CDoH in sub-Saharan Africa research, will be introduced. In small groups, participants will see a demonstration of, and apply, one method of their choice.

RESULTS:
Mapping multistakeholder engagement is an analytical method grounded in Nkrumah’s neocoloniality, that visualises the concentration of power within and across commercial and political spheres. Using data mapping corporate engagement in global governance, participants will examine the implications of such interactions for understanding tensions between multistakeholder approaches to sustainable development and action to tackle CDoH. Crowdsourcing is a method that leverages internet and smart phone technologies to enable mass public participation in collecting visual (photographic) data that “speaks” for people whose voices are usually excluded. Participants will explore setting up and adding photographic data to an online database platform. They will consider the theoretical underpinnings of methods that capture the lived experiences of structurally marginalised people. Community impact mapping is a participatory data collection method adapted from rapid rural appraisal methods. It intended to address epistemic injustice which is central to coloniality, by collecting data about citizens lived experiences of the impacts of commercial determinants of health, at the local level. Applying this method in the workshop, participants will draw on their lived experiences, to produce and analyse community map data.

CONCLUSIONS:
Workshop participants will develop capacity to consider coloniality in commercial determinants of health research and practical experience applying one methods.
