Mapping the Past Two Decades of Nutrition and Food Security in Iran: A Co-Word Network Analysis

Background: Food security in communities can prevent health complications, so investigators have made efforts to find its related factors through various fields. This study aims to draw a road map for nutrition and food security research in Iran. Methods: Web of Science, PubMed, Scopus, Embase, and Islamic World Citation Center were searched for eligible publications in nutrition and food security related to Iran for the two decades from 2001 to 2020. Content analysis was done by a co-word network technique using VOSviewer software. Results: Finally, 28,995 scientific publications among 50,444 search results were eligible to include in this study. The research map was drawn using 403,262 keywords obtained from the title and abstract of the papers. A 23.53% growth rate of publications was seen. Iranian articles were mainly published in scientific journals under 10 subject categories. The highly repeated keywords of "treatment", "plant", "age", "risk", and "consumption" were in publications. Moreover, the articles were categorized into thematic clusters of "environmental and climate change", "health ", "food industry and food safety", and "agriculture and water resources management" which were related to nutrition and food security. An increasing trend was observed in the number of publications during the past two decades in Iran. Conclusion: The relation of clinical nutrition, malnutrition, diet, and in recent years, food production and climate change with food security have been extensively studied by Iranian researchers. However, they have neglected studies on public health and policy in food and nutrition security, which reveals their dominant clinical or agricultural approach.
