 I like to think of the social determinants of health as where we live, where we learn, where we work, where we play, where we pray. So all of the factors around us that influence where we get to get our food from. And the one thing I want to remind people is that social doesn't just mean social in this context. It means social, economic, physical, structural, political barriers. There are many challenges in terms of research. One of the challenges precisely is to connect the different disciplines. That's what we call trans-disciplinarity. And then we need to find strategies to put together all these people so that they come up with ideas, with solutions, with proposals in terms of policy to address most of the problems. If we keep making research and even policy only for single problems, unfortunately we are not going to solve many of them. One of the great things about this journal in this meeting today is how interdisciplinary we are. In this room we have physicians, sociologists, policy, individuals, political scientists, economists. All of us need to come together if we're really going to solve these complex problems because these are complex problems and we need solutions that involve various disciplines and sectors coming together. And that's what's exciting to me about the journal, about the future of the journal. And really what we're doing here today is to sort of launch moving forward and emphasizing the social determinants of health. The journal has, or the discipline itself, is trans-disciplinary because it's rich a moment where we find an integration, say, of methods coming from the social science, merge with theories of political sociology to answer public health problems new disciplines are created. When there is this trans-disciplinarity with new methods, new theories that cannot be uniquely attributed to other disciplines but that are somehow original to this new body of knowledge. The idea is precisely to have social determinants in the title because having social determinants means that all these political, economic, cultural, ecological problems that are driving the health and the health inequalities in the population need to be studied together, need to be analyzed, and then we also need to evaluate policy. That's part of the proposals and the challenge we want to address in the journal.
