A city surveillance system for social health inequalities: the case of Barcelona. IJERPH. 2023 Feb 2;20(4):3536. DOI: 10.3390/ijerph200435361661-7827http://hdl.handle.net/10230/57248In the past, health inequalities were not prioritised in the political agenda of Barcelona. The change of city government (2015) was an opportunity to develop a Surveillance System for Social Health Inequalities in the city, which is described in this article. The design of the Surveillance System formed part of the Joint Action for Health Equity in Europe (JAHEE), funded by the European Union. Various steps were considered by the experts to set up the System: define its objectives, target population, domains and indicators, and sources of information; perform data analysis; implement and disseminate the system; define the evaluation; and perform regular data updates. The System considers the following domains: social determinants of health, health-related with behaviours, use of healthcare, and health outcomes, and includes eight indicators. As axes of inequality, the experts chose sex, age, social class, country of origin, and geographical area. The Surveillance System for Social Health Inequalities is presented on a website including different types of figures. The methodology used to implement the Surveillance System can be used to implement similar systems in other urban areas around the world.application/pdfeng© 2023 by the authors.
