Topics
Evidence for Action (E4A) grantees are working in a broad range of topic areas to assess the health outcomes of various interventions aimed at addressing key determinants of health, with a particular focus on improving population health and health equity. Below we highlight topics in which grantees are currently working. We aim to continue funding work in these areas, as well as expand our funding to support research on new topics.
