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

Area of Science:

• Public Health
• Sociology
• Health Services Research

Background:

• Healthcare disparities research is advancing but remains largely US-centric.
• The focus on race and ethnicity in the US context limits broader comparative inquiry.
• Policymakers globally are increasingly attentive to health disparities.

Purpose of the Study:

• Advocate for cross-national comparative research in health disparities.
• Highlight the utility of comparative studies in identifying institutional factors influencing disparities.
• Expand the scope of research questions beyond US-specific contexts.

Main Methods:

• Discuss methodological challenges inherent in comparative health disparities research.
• Outline existing solutions to these methodological challenges.
• Analyze the impact of social divisions on self-assessed health using World Values Survey data from Europe and the US.

Main Results:

• Socioeconomic status (SES) demonstrates a more consistent negative impact on health across different contexts compared to race/ethnicity or gender.
• Social fault lines, such as SES, have a demonstrable effect on self-assessed health.
• Findings suggest SES is a more universal determinant of health than race or gender.

Conclusions:

• The study represents an initial effort toward a research agenda on health inequalities within and across societies.
• Acknowledges limitations including a restricted number of countries and a single health measure.
• Emphasizes the need for further cross-national research to fully understand health inequalities.
