Avoidable cancers in the Nordic countries-the potential impact of increased physical activity on postmenopausal breast, colon and endometrial cancer

Background: Physical activity has been shown to reduce the risk of colon, endometrial and postmenopausal breast cancer. The aim of this study was to quantify the proportion of the cancer burden in the Nordic countries linked to insufficient levels of leisure time physical activity and estimate the potential for cancer prevention for these three sites by increasing physical activity levels. Methods: Using the Prevent macrosimulation model, the number of cancer cases in the Nordic countries over a 30-year period (2016-2045) was modelled, under different scenarios of increasing physical activity levels in the population, and compared with the projected number of cases if constant physical activity prevailed. Physical activity (moderate and vigorous) was categorised according to metabolic equivalents (MET) hours in groups with sufficient physical activity (15+ MET-hours/week), low deficit (9 to Results: If no one had insufficient levels of physical activity, about 11,000 colon, endometrial and postmenopausal breast cancer cases could be avoided in the Nordic countries in a 30-year period, which is 1% of the expected cases for the three cancer types. With a 50% reduction in all deficit groups by 2025 or a 100% reduction in the group of high deficit, approximately 0.5% of the expected cases for the three cancer types could be avoided. The number and percentage of avoidable cases was highest for colon cancer. Conclusion: 11,000 cancer cases could be avoided in the Nordic countries in a 30-year period, if deficit in physical activity was eliminated. (C) 2019 Elsevier Ltd. All rights reserved.Peer reviewe

Rationale for a Swedish cohort consortium

We herein outline the rationale for a Swedish cohort consortium, aiming to facilitate greater use of Swedish cohorts for world-class research. Coordination of all Swedish prospective population-based cohorts in a common infrastructure would enable more precise research findings and facilitate research on rare exposures and outcomes, leading to better utilization of study participants' data, better return of funders' investments, and higher benefit to patients and populations. We motivate the proposed infrastructure partly by lessons learned from a pilot study encompassing data from 21 cohorts. We envisage a standing Swedish cohort consortium that would drive development of epidemiological research methods and strengthen the Swedish as well as international epidemiological competence, community, and competitiveness.Peer reviewe

Swedish Law on Personal Data in Biobank Research: Permissible But Complex

This chapter describes the regulatory and organisational infrastructure of biobank research in Sweden, and how the introduction of the GDPR affects the possibilities to use biobank material in future research. The Swedish legislator has chosen a rather minimalistic approach in relation to the research exception in Article 89 GDPR and has only enacted limited general exceptions to the data protection rules. This may be partly explained by the comprehensive right to public access to official documents which gives researchers vast access to information held in registries, albeit conditioned on abiding by secrecy and confidentiality rules. The Swedish legislation implementing the GDPR includes a general exception from the data protection rules in relation to the right to access to official documents, which researchers also benefit from. However, confidentiality rules for different categories of information differ between sectors, which hinders an effective use of the registries in research. The regulatory regime for using biobank and registry data in Sweden thus involves both data protection and secrecy rules, which makes the legal landscape permissible but complex. The operationalisation of the research exception in Article 89 GDPR is analysed against this background. Special attention is given to the possibility to link personal information derived from biobanks with personal information from other data sources, including large national population based statistical registries as well as information from national clinical registers
