[Intersectionality: a key factor for studying and addressing social inequities in health]

The intersectional approach helps to understand how social health inequalities emerge from the interaction of multiple axes of vulnerability, such as gender, social class, ethnicity, age, or migration status, and how these intersect with institutional structures and public policies. Applying this perspective to the health field requires moving beyond fragmented views and adopting analytical and intervention strategies that acknowledge the complexity of social determinants. Incorporating intersectionality into research, professional practice, and policymaking implies revising theoretical frameworks, methodologies, and information systems to make visible the experiences of the most disadvantaged groups. It also calls for stronger collaboration across sectors, disciplines, and decision-making levels, as well as for promoting community participation spaces that integrate diverse forms of knowledge. This article summarizes the main reflections and lessons from the event "Intersectional Approach to the Analysis and Intervention on Social Health Inequalities" emphasizing the need to translate intersectionality into operational tools to guide public action toward health equity.
