RT Journal Article SR Electronic T1 The international and domestic politics of type 2 diabetes policy reform in Brazil JF BMJ Global Health JO BMJ Global Health FD BMJ Publishing Group Ltd SP e002457 DO 10.1136/bmjgh-2020-002457 VO 5 IS 9 A1 Eduardo J Gómez YR 2020 UL http://gh.bmj.com/content/5/9/e002457.abstract AB Introduction Understanding the international and domestic political factors influencing the evolution of type 2 diabetes policies and primary care institutions is a new area of scholarly research. This article contributes to this area of inquiry by illustrating how a government’s shifting foreign policy aspirations, that is, to establish the government’s reputation as an internationally recognised leader in type 2 diabetes policy, and presidential electoral incentives provide alternative insights into the evolution of type 2 diabetes treatment policies and primary care institutional reforms.Methods I conduct a single-case study analysis with the usage of qualitative data; quantitative statistical data on epidemiological trends and government policy spending is also provided as supportive evidence.Results The case of Brazil illustrates how a reduction in foreign policy commitment to international reputation building in health as well as presidential electoral incentives to use diabetes policy as an electoral strategy account for a decline in sustaining policy and primary care institutional innovations in response to type 2 diabetes.Conclusion Future scholars interested in understanding the lack of sustainability and effectiveness in type 2 diabetes programmes should consider investigating the complex international and domestic political factors influencing political interests, incentives and commitment to reform.
