Abstract
BACKGROUNDS: Diabetes is one of the most common metabolic disorders worldwide. This study aim was to provide detail analysis of diabetes research output and its trend in Iran as well as in the world and compare them. METHODS: Data was retrieved from PubMed database using a suitable search strategy and application of proper operator "AND", "OR" and "NOT". All English documents published from 2008 to 2012 were included. Meeting abstract, letter to the editor, guidelines, consensus and reviews were excluded. Obtained documents for Iran and world were categorized in eleven groups including diabetes management, education, paediatrics, nutrition, epidemiology, diabetes complications, stem cells, gestational diabetes mellitus (GDM), psychiatrics, genetics and prevention and were compared. RESULTS: Total number of DM publications was 59513 for world and 648 for Iran. Trend of DM publications was increasing during the 5 years with a growth rate of 22.5% for world and 23.4% for Iran. Contribution of Iran in the world diabetes output reached 1.08 in 2012. The most and the least number of DM documents were related to complications and preventions, respectively both in Iran and the world. Three leading countries with highest proportion of RCTs (randomized clinical trial) to their total DM publications were Italy, Germany and Iran. CONCLUSION: The most number of diabetes research was in the field of diabetes complication, management and genetics in the world as well as in Iran. During the 5-year period, despite of the world sanctions against Iran, diabetes research trend was increasing in Iran relatively parallel to the world research and sanction had no significant effect on Iran.
