Aim This study examined the outputs of research papers in diabetes from 31 European countries between 2002 and 2013, and their funding.Methods Diabetes research papers in the Web of Science were identified by means of a filter based on journals and title words. For 2009-2013 papers, the funders were coded to show their sector and nationality.Results Europe published 40 547 diabetes papers in the 12 years between 2002 and 2013. Denmark, Sweden and Finland published the most relative to their wealth, but the UK published the most absolutely despite an apparently low burden (as measured by disability-adjusted life years). The largest source of funding was government (30%), followed by the non-profit sector (18%) and industry (13%). The European Commission supported 2.7% of papers, but more in Latvia (33%) and Estonia (16%). Based on an estimated cost per paper of €260 000, the annual research expenditure in Europe was approximately €986 million in 2013.Conclusions The European diabetes burden in disability-adjusted life years increased by one third between 2002 and 2012, but its output of research papers has decreased from 44% to 36% of the world total. This decrease needs to be reviewed in the context of European non-communicable disease research policy. Diabet. Med. 34, 1354-1360 Introduction Diabetes represents a major global health problem and, together with other non-communicable diseases, has led to a major policy document on its prevention and control from the World Health Organization (WHO) [1]. Worldwide, 1.5 million deaths were directly associated with diabetes in 2012, and 2.2 million more were related to high blood glucose [2]. In the European region in 2015, almost 60 million people had diabetes. Based on data from the WHO website on the disease burden for the 31 European countries (EUR31; the 28 European Union Member States, plus Iceland, Norway and Switzerland) between 2002 and 2012, the average percentage of disability-adjusted life years (DALYs) from diabetes increased from 2.0% to 2.6% [3]. In 2012, the figure ranged from 1.3% in the UK to 4.9% in Cyprus. Countries in the Mediterranean and Southern Europe (Portugal 4.3%, Spain 3.7%, and Italy 3.5%) had the highest levels, except for Greece (2.2%). Besides the UK, the lowest percentages occurred in Romania, Lithuania and Finland (1.8%) and Iceland (2.0%).This paper presents the results of a bibliometric study of outputs (i.e. scientific papers) and funding for diabetes research from 2002 to 2013. The study, of the EUR31 countries, was performed as part of the Mapping NonCommunicable Diseases (NCD) project, funded by the European Commission under the 7th Framework Programme. The aim was to map research activity and assist research funding organizations such as the Commission to identify gaps and overlaps in the current state of diabetes research, and point out areas on which to focus future strategies. Previous studies that have applied a bibliometric approach to the outputs of diabetes research have mainly focused on a specific type of diab...
