Background: Although there셲 been sharp increase in the use of heated tobacco product (HTP) in Korea, the accuracy has not been verified.
Methods: 121 participants to use any type of tobacco (conventional cigarette (CC), electronic cigarettes (EC), and/or HTP) and to complete an online survey in June 2019 were recruited. They were interviewed and classified into seven categories according to their combination
Results: Differences between self-reported and interviewer-rated tobacco use pattern was 39.7% (48/121). Great differences of prevalence were observed in HTP only (0% vs 24.8%), triple use (18.2% vs 4.1%) and dual use of CC/HTP (22.3% vs 14.0), but relatively small differences were in CC only (41.3% vs 42.1%), EC only (7.4% vs 9.1%), and dual use of CC/EC (10.7% vs 5.8%).
Conclusion: There was a big difference between self-reported and interviewer-related tobacco use pattern, especially among those who currently used HTP regardless of CC or EC use
