Analysis of Publication Trends in Childhood Obesity Research in PubMed Since 1945.

Background: Childhood obesity (CO) has become a true epidemic and a subject of increasing publications. The aim of this study was to assess if the number of publications in that field increases over time in proportion to the epidemic, and also according to socioeconomic factors. Methods: A PubMed search was carried out to extract articles related to CO published between 1945 and 2017. Data were downloaded from PubMed and processed through a dedicated parser. Socioeconomic data were collected from international organizations. Results: Overall, 36,554 articles were retrieved among 3329 journals, one-third of them being concentrated in 44 journals. The annual growth rate of publications on CO was on average 11.6% per year between 1990 and 2016, whereas the growth rate of articles on pediatrics or of the total articles indexed in MEDLINE was 2.6% and 4.4%, respectively. The most productive countries were the United States (37.80%), the United Kingdom (6.24%), and Italy (4.56%). There was a significant relationship between publications on CO in a country and prevalence of CO in that country (p = 0.002) and between evolution of the number of publications and evolution of the Human Development Index (p = 0.01). Following exponential growth, CO publications reached a plateau in 2013, whereas publications targeted on obesity in infants continue to increase. Conclusions: Research on CO has risen markedly in the last two decades, with a higher growth rate than biomedical research overall, as a result of the worldwide obesity epidemic and also due to specific socioeconomic factors.

Epidemiology of systematic reviews in imaging journals: evaluation of publication trends and sustainability?

PURPOSE: To evaluate the epidemiology of systematic reviews (SRs) published in imaging journals. METHODS: A MEDLINE search identified SRs published in imaging journals from 1 January 2000-31 December 2016. Articles retrieved were screened against inclusion criteria. Demographic and methodological characteristics were extracted from studies. Temporal trends were evaluated using linear regression and Pearson's correlation coefficients. RESULTS: 921 SRs were included that reported on 27,435 primary studies, 85,276,484 patients and were cited 26,961 times. The SR publication rate increased 23-fold (r=0.92, p<0.001) while the proportion of SRs to non-SRs increased 13-fold (r = 0.94, p<0.001) from 2000 (0.10%) to 2016 (1.33%). Diagnostic test accuracy (DTA) SRs were most frequent (46.5%) followed by therapeutic SRs (16.6%). Most SRs did not report funding status (54.2%). The median author team size was five; this increased over time (r=0.20, p<0.001). Of the studies, 67.3% included an imaging specialist co-author; this decreased over time (r=-0.57, p=0.017). Most SRs included a meta-analysis (69.6%). Journal impact factor positively correlated with SR publication rates (r=0.54, p<0.001). Magnetic resonance imaging (MRI) and 'vascular and interventional radiology' were the most frequently studied imaging modality and subspecialty, respectively. The USA, UK, China, Netherlands and Canada were the top five publishing countries. CONCLUSIONS: The SR publication rate is increasing rapidly compared with the rate of growth of non-SRs; however, they still make up just over 1% of all studies. Authors, reviewers and editors should be aware of methodological and reporting standards specific to imaging systematic reviews including those for DTA and individual patient data. KEY POINTS: • Systematic review publication rate has increased 23-fold from 2000-2016. • The proportion of systematic reviews to non-systematic reviews has increased 13-fold. • The USA, UK and China are the most frequent published countries; those from the USA and China are increasing the most rapidly.

Social inequality in health: revisiting moments and trends in 50 years of publication of RSP / Desigualdade social em saúde: revisitando momentos e tendências nos 50 anos de publicação da RSP

ABSTRACT This study describes the frequency and types of articles on social inequalities in health published in 50 years of the Revista de Saúde Pública, taking as reference some milestones that were used as guidelines to develop the research on this theme. Checking titles, keywords and abstracts or full texts, we identified 288 articles whose central or secondary focus was social inequalities in health. Corresponding to just 1.8% in the initial years, articles on social inequalities in health have represent 10.1% of the articles published in the last decade. The designs used were mainly cross-sectional (58.0%) and ecological (18.1%). The most analyzed themes were: food/nutrition (20.8%), mortality (13.5%), infectious diseases (10.1%), oral health (9.0%), and health services (8.7%). Articles focused on the analysis of racial inequalities in health amounted to 6.9%. Few articles monitored the trends of social inequalities in health, essential enterprise to assess and support interventions, and an even smaller number evaluated the impact of policies and programs on the reduction of social inequalities in health.

RESUMO Este estudo descreve a frequência e os tipos de artigos sobre desigualdades sociais em saúde publicados nos 50 anos da Revista de Saúde Pública, tomando por referência alguns marcos que balizaram o desenvolvimento das investigações nessa temática. Checando títulos, palavras-chave e resumos ou textos completos, foram identificados 288 artigos cujo foco central ou secundário era desigualdades sociais em saúde. Correspondendo a apenas 1,8% nos anos iniciais, artigos sobre desigualdades sociais em saúde chegaram a representar 10,1% dos publicados na última década. Os desenhos utilizados foram principalmente transversais (58,0%) e ecológicos espaciais (18,1%). Os temas mais analisados foram: alimentação/nutrição (20,8%), mortalidade (13,5%), doenças infecciosas (10,1%), saúde bucal (9,0%) e serviços de saúde (8,7%). Artigos voltados à análise de desigualdades raciais em saúde somaram 6,9%. Poucos artigos monitoraram as tendências das desigualdades sociais em saúde, empreendimento essencial para avaliar e subsidiar intervenções, e um número ainda menor avaliou o impacto de políticas e programas na redução das desigualdades sociais em saúde.

Health policy on the pages of revista de saúde pública / A política de saúde nas páginas da revista de saúde pública

ABSTRACT We carried out a narrative review of the scientific production in the area of Policy, Planning and Management in Revista de Saúde Pública (RSP), between 1967 and 2015. All the fascicles of RSP, in the period, were accessed via SciELO platform, which provides all articles online. We selected and classified the articles according to the main topics of scientific production in the area of Policy, Planning and Management. Revista de Saúde Pública has published 343 articles on this subject, with significant growth in the last two decades. The most discussed topics were Health Economics, Primary Health-care, Access and Use of Health Services, and Evaluation of Services and Programs. In the last decade, the topics of Policy and Access to Medicines and Public-Private Relationship, including judicialization, gained importance. The pages of RSP embraced the vast and diverse production of Policy, Planning and Management in its first 50 years, contributing to the consolidation of the area in Brazil.

Tendências da produção científica brasileira de enfermagem sobre violência no período de 2003 a abril de 2008 / Brazilian nursing scientific production on violence: trends in the period of 2003 to april, 2008 / Tendencias de la producción científica brasileña de enfermeria sobre la violencia, en el periodo de 2003 a abril de 2008

A violência como problema social vem refletindo, em todas as esferas, no cotidiano das pessoas. Por essa razão, é importante considerarmos como ela está sendo vista e tratada no setor da saúde, em especial na enfermagem. Consideramos, pois, que se torna essencial estudarmos sobre essa temática identificando e analisando a existência de artigos científicos sobre violência. Para tanto, analisamos a produção científica brasileira de enfermagem sobre violência, publicadas no período de 2003 a abril de 2008, nas bases de dados da Biblioteca Virtual em Saúde/Biblioteca Regional de Medicina (BVS/BIREME). Para tanto utilizamos o Lilacs, o Medline, Scielo e o BDENF, enfocando o método, a região brasileira em que se realizou a pesquisa, a categoria do autor (docente, discente de pós-graduação e graduação, enfermeiro assistencial), idioma, ano de publicação, tipo de violência abordada e periódicos veiculados. Foram encontrados 154 artigos e desses foram selecionados 47. Desse total, em 33 (70,2%) foi utilizada uma abordagem qualitativa, 17 (36,2%) realizados na Região Sudeste, 32 (68,1%) por docentes, 39 (83,0%) na língua portuguesa, no ano de 2007, 20 (42,6%); 22 (46,8%) versaram sobre a violência contra a criança e o adolescente. O periódico que mais publicou essa temática foi a Latino-Americana de Enfermagem, com 10 publicações (21,3%). Conclui-se que a produção científica brasileira sobre a temática da violência ainda é escassa, mas que, no período pesquisado, houve um gradativo crescimento em relação a essas publicações.

As a social problem, violence has been reflecting its consequences over people's daily lives. For such reason, it is important to understand how it is seen and addressed by health professionals, especially by nurses. It is therefore essential to study this issue by identifying and analyzing scientific paper on the theme. With this objective, we analyzed all Brazilian nursing scientific production on violence published in the period of 2003 to April, 2008. Articles from Biblioteca Virtual em Saúde / Biblioteca Regional de Medicina (BVS/BIREME) were accessed using LILACS, MEDLINE, SCIELO and BDENF database. We focused on methodology, Brazilian region where the study was performed, author's degree (professor, undergraduate or postgraduate student, assistant nurse), language, yearof publication, type of violence covered and publication vehicles. A total of 154 articles were found, out of which 47 were selected. Qualitative approaching was used in 33 papers (70, 2%). Seventeen studies (36, 2%) had been performed in the Southeast of Brazil, 32 (68, 1%) had been carried out by professors, 39 (83, 0%) were written in Portuguese and 22 (46, 8%) dealt with violence against children and teenagers. The publication that most frequently had articles on the subject was Revista Latino-Americana de Enfermagem, with a total of 10 papers (21,3%). We conclude that Brazilian scientific production on violence is still scarce, even though there has been a gradual increase in the studied period.

La violencia como problema social se refleja en todos los ámbitos del día a día de las personas. Por ese motivo es importante saber como se la siente y se la trata en el sector de la salud, en especial en enfermería. Consideramos, por lo tanto, esencial estudiarla identificando y analizando artículos científicos sobre la violencia. Analizamos la producción científica brasileña de enfermería sobre la violencia publicada del 2.003 a abril del 2.008 en las bases de datos de la Biblioteca Virtual en Salud/ Biblioteca Regional de Medicina (BVS/BIREME). Para ello utilizamos LILACS, MEDLINE, SCIELO y BDENF, enfocando el método, la región brasileña donde se realizó la investigación, la categoría del autor (docente, discente de posgrado y grado, enfermero asistencial), idioma, año de publicación, tipo de violencia enfocada y medio de publicación. Se encontraron 154 artículos de los cuales se seleccionaron 47. De ese total: 33 (70,2%) se emplearon en práctica cualitativa, 17 (36,2%) en la región Sureste, 32 (68,1%) por docentes, 39 (83,0%) en idioma portugués, 20 en el 2007 (42,6%); 22 (46,8%) sobre violencia contra el niño y adolescente. Quien más publicó sobre el tema fue la Revista Latinoamericana de Enfermería con 10 artículos (21,3%). Llegamos a la conclusión de que la producción científica brasileña sobre la violencia es escasa y que dentro del período investigado hubo un crecimiento gradual de las publicaciones que tratan del tema.
