This commentary introduces this volume's symposium on "Comparative Approaches to Reducing Health Disparities." Disparities in the health of socially and economically disadvantaged compared with more advantaged populations are observed worldwide. The lack of progress in addressing these disparities compels a continuing search for new ideas and evidence about potential solutions as well as efforts to understand when and where these solutions work and how they work. The symposium consists of five in-depth reviews led by established scholars who approach the topic from their different disciplinary and topical perspectives. Taken together, these reviews point out the conceptual and methodological opportunities for generating more effective disparities research within biomedical, public health, and health services approaches, the value of also applying theory and methods from disciplines such as political science and economics to health disparities research, and insights to be gained from comparisons of how disparities occur and are remedied in different societies.

SYMPOSIUM INTRODUCTIONDiverse social and political realities create huge, predictable differences in health outcomes among nations and between population groups within nations (2,3,8,10,12,19 Yet, disparities persist even in the most "egalitarian" societies. This arena of research and policy is extremely complex as well as political and politically sensitive. The call for remedies that involve government interventions in the lives of individuals and for new resources or new uses of existing resources to achieve equity becomes interwoven with advocacy and political stances to keep the issue on public policy agendas. Health disparities imply or confirm injustice, systematic unfair treatment (e.g., of racial/ethnic minorities, immigrants, the poor, or those less educated), or at least a failure of societies to distribute equitably the resources needed to support health for all. Uncertainties about where and how to intervene to eradicate disparities arise because of the plethora of potentially relevant causes, variations in the effects of these causes across the life course, and cumulatively, the fact that these causes are often interrelated, and the diverse groups that are disadvantaged. In addition, interventions to address disparities must identify focal and leverage points that are modifiable. This is highly problematic because health or social disadvantage is rooted within the institutions, social stratification, and cultural norms of societies. Such societal characteristics are difficult to change, perhaps especially because they provide the underpinnings of power, privilege, and social advantage. Failure to acknowledge these fundamental, structural influences on disparities leads to a futile focus on changing the health-related behaviors of people in...
