Abstract
Health equity is central to achieving sustainable development goals and COVID-19 has emphasized its importance. Ensuring health equity is prominent in policy discussions and decision-making is a critical challenge in all countries. Understanding the policy space for actors to promote health equity in the policy process may help to strengthen prioritization of equity in policy and programme discussions and decisions. Authors developed a conceptual framework for policy space based on a narrative literature review. This comprised five key elements and their associated factors, i.e. context, policy circumstances, policy characteristics, actor engagement and policy spaces. Authors then applied it in Myanmar during a period of political transition, using a qualitative case study design. Findings showed that political transition provided an important 'policy window' to develop more equitable health policy in Myanmar. Changing policy circumstances offered opportunities for advancing pro-equity policy. However, lack of visibility of health equity and long-standing inequalities were important challenges to policy space. Within a changing context, actors at individual and organizational levels used a range of policy spaces to advance pro-equity health policy. Learning from using the framework in Myanmar was incorporated into a revised framework. Application of this revised framework could provide valuable insights into the opportunities to promote a pro-health equity approach across policy and programme discussions and decision-making for actors trying to promote equity in other transition and non-transition contexts.
