A Bibliometric Study of Scientific Literature on Obesity Research in Web of Science Database (2008-2020): Evidence from the MENA Region.

Obesity has increasingly become a health threat in the Middle East and North Africa (MENA) countries. This study aimed to investigate the scientific publications on obesity in the MENA countries during 2008-2020. A longitudinal analysis of 13 years (2008-2020) of bibliographic data from obesity-related articles was performed. Web of Science core collection (WoS) was searched for bibliographic data. The bibliometric indicators including overall productivity and collaboration along with the prevalence of obesity and socioeconomic status were used to assess and compare the context of obesity research efforts in the MENA region. The overall obesity-related articles of the MENA countries cumulated to 23680 publications. The MENA region accounted for a 6.5% global publication share in obesity research. Turkey contributed the highest rate of total publications (n=6162) followed by Iran (n=5302) and Israel (n=2847). Iran and Turkey had the lowest rates of international collaborations. The overall obesity research was not significantly associated with socio-demographic index (SDI) measure (r=-0.26, P=0.27). No significant association was found between Gross National Income (GNI) per capita and the overall production of obesity research (r=0.41, P=0.08). Additionally, obesity research was not significantly associated with the prevalence of obesity in the countries (r=0.24, P=0.30). This study observed an increased share of scientific productivity in the field of obesity from the MENA countries. Neither SDI, GNI per capita, nor obesity prevalence was not significantly associated with the overall productivity of the region.

Comparing the post-WWII publication histories of oceanography and marine geoscience

Oceanography and marine geosciences are closely related subjects, though they have had differing influences. The UK, which has experienced the financial benefits of North Sea oil and gas, while also having an extensive fishing industry and a science base linked to other English-speaking countries and European countries, potentially illustrates some changing influences and collaborative tendencies well. In this article, differences in article publication rates and collaborative tendencies, both globally and for the UK, are examined using the Web of Science™, Scopus™ and Georef™ for the period 1946–2018. The results show that publication rates of global oceanography articles rose exponentially faster than all global scientific publishing from the mid-1960s to 1980. Subsequently, the exponential rate of increase slowed though has remained faster than global science publishing. Global Marine Geoscience publication rates increased into the late 1980s, but have since declined. UK oceanography has roughly followed global trends, though its share of global oceanographic publishing declined from 28% in the 1950s to 8% in 2018. UK Marine Geoscience publishing has also generally followed global trends for that field. However, its share of global publications abruptly increased from 4.9% (average 1960–1980) to 13.2% by 1990, largely due to articles arising from UK participation in the Deep-Sea Drilling Project and Ocean Drilling Program. Oceanography and marine geoscience have also experienced strongly differing histories of collaborative articles over the last four decades. While oceanographic articles co-authored with researchers in other countries have been steadily increasing as a share of total UK Oceanography articles, those of marine geoscience peaked in 1990 and have since declined, though remained at high levels similar to those experienced by 2018 in Oceanography. Comparing global publication rates in both fields with measures of data and sample collection at sea suggests fundamental changes occurred in the way research was carried out. For example, Marine Geoscience publication rates were strongly correlated with geophysical track-line distances for the decade until ~1970, but were inversely correlated for the decade after then. This reflects, for example, the development of plate tectonics, which partly involved analysis of existing marine geophysical data, improved equipment capabilities and the increased role of scientific drilling.
