Understanding Health Inequalities Research Capacities: Insights and Recommendations From Comparing Two High Income Settings.

Generating evidence on health inequalities (HI) is necessary to raise awareness of these issues, describe and monitor their evolution, analyze their causes, and inform interventions aiming to improve health equity. Yet not all cities and countries have the capacity to produce this type of research. Recent research provides new contextual and causal insights into this research production process, and in-depth understanding on why and how this type of research is produced in certain settings. This article aims to analyze two recent case studies that have uniquely explored this process in two high producers of HI research and high-income country settings to identify learning and distil recommendations, which may be insightful for other settings. Expanding and investing in this line of research is critical, particularly in places with lower HI research output and related capacity, in order to identify key contextual conditions and mechanisms that may enable or hinder this process. This new knowledge could guide the development of new HI research capacity strengthening strategies to foster this research in different settings, worldwide. More understanding is also needed on the relationship between HI research, policy, and action in order to tackle HI.
