This Research Partnership will aim to strengthen our research capacity in investigating inequalities in access to early diagnosis and treatment for the two most common female cancers in Brazil: breast cancer and cervical cancer. The planned work will involve: 1. Gaining access to, and linking, at a national level, SISMAMA and SISCOLO national data to Censuses, hospital and mortality records, socioeconomic surveys, and Bolsa Familia. 2. Comparing different approaches to data linkage (e.g. probabilistic vs. deterministic; individual record linkage vs. area-based aggregated level). 3. Developing a multi-disciplinary conceptual framework to identify demand (e.g. socio-economic status, belief system) and supply determinants (e.g. services availability) of inequalities in health care using such comprehensive data linkage. 4. Organising a workshop in the UK to discuss the methodological challenges associated with the analyses of large routinely-collected datasets (e.g. missing data) and the modelling of inequalities in access to health care. 5. Organizing a workshop in Brazil to discuss the findings, and their implications for optimizing strategies for early detection ("downstaging") and treatment of BC and CC cancers in the country and for designing more "in-depth" studies of the demand and supply barriers to health care access. 6. Building research capacity in Brazil by training five Brazilian students/junior researchers through scholarships. 7. Preparing methodological guidelines on "best practice" for: (i) linking health-related databases and (ii) analyzing multi-dimensional pathways to health care, and identifying demand and supply barriers underlying inequalities.
