Knowledge production in Iranian social determinants of health research centers: Toward health equity

Background: As the partner country of the WHO Commission on Social Determinants of Health (SDH), Iran has expanded the knowledge based on the social determinants of health- as one of commission recommendations- by establishing SDH research centers to collect evidence and design responses to the existing health equity gap. Considering the importance of the role assigned to these research centers, this study aimed to present the knowledge production of SDH research centers and determine their status in Iran's health research system (HRS). Methods: In this cross sectional study, research performance of SDH research centers was assessed based on international research indicators and compared with national medical research centers and HRS knowledge production. Then, SDH research centers were scored and ranked based on the research indicators. Results: Out of 37 approved SDH research centers, the knowledge performance of 33 research centers was reviewed. The total number of academic members was 334. The number of these centers' indexed published articles and the proportion of published articles per academic member have been doubled from 483 and 1.44 in 2015 to 984 and 2.94 in 2017. In this period, the number of citations of the past 5-year publications was 4355 according to Scopus database. The proportions of these centers' high-quality publication (Q1) and international collaborations per published articles were 14.8 and 8.25. In ranking, the first to third ranks were occupied by SDH research centers of Kermanshah, Kurdistan, and Qazvin Universities of Medical Sciences. Conclusion: Although knowledge production seems desirable in mentioned research centers, it is essential to create a virtual research network to increase intersectoral collaboration and develop strategies to solve the puzzle of gathering evidence on the social determinants affecting health inequities.
