At an International Epidemiological Association (IEA) event in Abuja, director Aluisio Barros led sessions on inequality metrics and took part in the official presentation of the new edition of the Dictionary of Epidemiology

The director of the International Center for Equity in Health (ICEH/UFPel), Aluisio Barros, was part of the faculty of the Early Career Epidemiologists Workshop, held by the International Epidemiological Association (IEA) from 19 to 25 July in Abuja, Nigeria. The event brought together early career epidemiologists from African countries for an intensive week of training with internationally renowned researchers.

During the workshop, Barros led sessions on the social determinants of health and on measures of health inequality, fostering the exchange of experiences and deeper engagement with methodologies for measuring population-level disparities.

An editorial milestone for the Equiplot

One of the highlights of the programme was the official presentation of the new edition of the Dictionary of Epidemiology, led by its editor, epidemiologist Miquel Porta. The work, regarded as the field's leading conceptual and terminological reference worldwide, now formally includes the Equiplot among its entries.

Created by ICEH in 2012, the Equiplot is a graphical tool designed to display the coverage of interventions and health outcomes across population subgroups. Its main innovation lies in its ability to translate patterns of absolute inequality into intuitive, easy-to-read charts.

"Seeing the Equiplot added to the field's reference dictionary alongside the fundamental concepts of our discipline reaffirms that simplicity in communicating complex data is an indispensable tool for evidence-based policymaking," said Aluisio Barros.

Over the past decade, the Equiplot has become an established analytical resource in major international reports, including those of the Countdown to 2030 initiative and of international agencies linked to the UN, and in a growing number of scientific publications worldwide.
