Improving the career progression of women and ethnic minorities in public health universities has been a longstanding challenge, which we believe might be addressed by including staff diversity data in university rankings. We present findings from a mixed methods investigation of gender-related and ethnicity-related differences in career progression at the 15 highest ranked social sciences and public health universities in the world, including an analysis of the intersection between sex and ethnicity. Our study revealed that clear gender and ethnic disparities remain at the most senior academic positions, despite numerous diversity policies and action plans reported. In all universities, representation of women declined between middle and senior academic levels, despite women outnumbering men at the junior level. Ethnic-minority women might have a magnified disadvantage because ethnic-minority academics constitute a small proportion of junior-level positions and the proportion of ethnic-minority women declines along the seniority pathway.

To identify in the international scientific literature the obstacles and potential promoters for the advancement of women academics and researchers in biomedical sciences during their professional careers. PubMed, Scopus, CinahlPlus, Cochrane Database of Systematic Reviews, PsycInfo and Sociological Abstracts were systematically searched for articles published in English and Spanish between January 2006 and December 2016 on the phenomenon of the glass ceiling in women academics and researchers in biomedical sciences. The screening was carried out by independent reviewers. A total of 2254 studies were found, of which 23 were included in the review. The obstacles identified for the promotion of women academics and/or researchers in biomedical sciences are: gender bias in the evaluation of research results, individualism and lack of collaboration, women's lack of influence, the existence of gender inequalities in access to employment. The perception of sexism and discrimination in the work environment, and the difficulties in reconciling work and family life. The promoting elements are: examples of women in leadership positions, mentoring, facilitating conciliation, transparency in recruitment, participation in decision-making, gender assessment of research, awareness of gender inequalities in institutions, promoting collaboration, and pay equity. By enhancing the elements favouring the promotion of academic women in biomedical sciences would help to reduce the glass ceiling in the career paths of women academics and health science researchers by increasing their participation, leadership and representation. A change of organizational and institutional values is required to achieve this.
