Abstract
The intersectionality seek to expand the explanations for inequalities in health in contemporary society. This study sought to map the conceptual and methodological approach of intersectionality using quantitative data analysis studies on health inequalities. Systematic review was held in April 2017 using multiple sources of information. In-clusion criteria were articles that converged with the themes of health care dispari-ties, gender identity, ethnic groups, social class, and public health and that simulta-neously applied the concept of intersectionality in the analysis. Exclusion criteria were articles that only mentioned intersectionality without discussing its applicability and articles exclusively theoretical and conceptual or with a qualitative methodolog-ical approach. The search strategy resulted in 1,763 articles. After removing the du-plicates and articles by titles and abstracts, 20 articles composed the corpus of analysis of the review. The methodological resources most often used in the intersec-tional analyses were stratification of social markers of difference, interaction analysis, multivariate regression models, and multilevel analysis. The perspective of inter-sectionality allows for a greater specificity in mapping health disparities. However, caution is required in the subdivision of the population arising from the stratification of variables, without forgetting to focus on the interactive systems of power at the source of health inequalities.
