Contextualizing Disparities: The Case for Comparative Research on Social Inequalities in Health.

Purpose: Research on healthcare disparities is making important descriptive and analytical strides, and the issue of disparities has gained the attention of policymakers in the US, other nation-states, and international organizations. Still, disparities scholarship remains US-centric and too rarely takes a cross-national comparative approach to answering its questions. The US-centricity of disparities research has fostered a fixation on race and ethnicity that, although essential to understanding health disparities in the United States, has truncated the range of questions researchers investigate. In this article, we make a case for comparative research that highlights its ability to identify the institutional factors may affect disparities.

Methodology/approach: We discuss the central methodological challenges to comparative research. After describing current solutions to such problems, we use data from the World Values Survey to show the impact of key social fault lines on self-assessed health in Europe and the U.S.

Findings: The negative impact of SES on health is more generalizable across context, than the impact of race/ethnicity or gender.

Research limitations/implications: Our analysis includes a limited number of countries and relies on one measure of health.

Originality/value of paper: The paper represents a first step in a research agenda to understand health inequalities within and across societies.
