Changes in Citations and Downloads of Papers Published in Journal of Environmental and Occupational Medicine, 1984-2013

Objective ] To observe the pattern of changes in citations and downloads of papers published in the Journal of Environmental and Occupational Medicine （JEOM） since its launch in 1984. Methods ] From 1 May to 10 July 2014, information on total number, citation frequency, and download frequency of papers published in the JEOM from 1984 to 2013 were collected by searching through China National Knowledge Infrastructure （CNKI）. The contents and characteristics of the most cited or downloaded papers were analyzed. Results ] From 1984 to 2013, a total of 6000 papers in 170 issues of 30 volumes published in the JEOM; the total citation frequency was 1036, and the total downlOad frequency was 10721. The peaks of average citation and downloaded frequency were both located between 2002 and 2008. The annual average citation frequency of the papers published in 2000-2013 （709.3） was significantly higher than that in the 1990s （78.5） or 1980s （16.9）. A positive correlation was found between citation frequency and download frequency （r=0.653, P 〈 0.01）, while it had no correlation with citation frequency （r=-0.218, P〉0.218）. Highly cited or downloaded papers were focused on the following topics： associations between pesticide, dust, heavy metals or tumor and occupational populations as well as relevant detection technologies at workplaces; analysis on pollution levels of formaldehyde in decorative materials and plasticizers in edible oil; effect comparison of residential air purifiers; air and soil environment pollutions and health risk assessments, etc. Among the leading 150 cited papers, reviews, survey study, and experimental study ranked the top three （34.67%, 28.67%, and 23.33%, respectively）, with the average citation frequencies of 29.12, 29.49, and 24.49 and the average download frequencies of 466.44, 216.67, and 165.86, respectively. The proportion of editorial board members in the leading contributing authors in all analyzed time intervals were higher than others. The EHP c
