Background: Since the launch of the Philip Morris IQOS heated tobacco products (HTPs) in 2014, studies on the process have been conducted worldwide. In the current study, global and domestic HTP-related papers published from 2015 to 2020 were analyzed, and research trends were compared.
Methods: PubMed, KoreaMed, and Journal of the Korean Society for Research on Nicotine and Tobacco databases were searched for studies on HTPs published between 2015 and 2020. Among these, studies unrelated to HTPs and studies that were not original articles were excluded. For the reviews and editorials, a separate analysis was conducted to identify academic interests. We collected, categorized, and analyzed data such as journals, nationality of the first author, number of citations, research methods, and topics.
Results: A total of 143 papers related to HTPs, published from 2015 to 2020, were searched on PubMed, with the number per year significantly increasing in 2018. Most papers corresponded to human:non-interventional studies when classified according to methodology. When categorized according to the topic, emission and toxicology were the most studied subjects worldwide, but they accounted for a small portion in domestic studies.
Conclusion: The publication of articles on HTPs is on the rise worldwide. The same is true in Korea; however, methods of studies are limited there, and not enough studies on emission and toxicology have been conducted. With the continuing release of new forms of heated tobacco, more research on various methods is needed.
