BCA-WA-ETHICS (Building capacities in gender mainstreaming for ethics committee members from Senegal to West Africa) is a cooperation between the University of Zaragoza, the West African research institution IRESSEF (Institute for Health Research, Epidemiological Surveillance and Training), and the Senegalese Ministry of Health and Social Action. BCA-WA-ETHICS is funded by the European & Developing Countries Clinical Trials Partnership (EDCTP). The main aim of the project is to facilitate the incorporation of a gender perspective into health research in West Africa, through the training of scientists and ethicists in sex- and gender-based analysis and gender mainstreaming approaches in research protocol evaluation and research site inspection. In addition, the project will train West African research institutions in the design and implementation of gender equality plans. Furthermore, research will conducted on the gender-related barriers against the educational and professional development of West African female scientists and health researchers. We expect the project to contribute to the achievement of the 3rd and 5th UN Sustainable Development Goals by promoting gender equality in health research.
