Background: Our objective was to identify trends in research on electronic cigarettes and propose potential research topics for future investigations in South Korea.Methods: This study followed the systematic literature review reporting guidelines detailed in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to assess available research on the health effects of electronic cigarette use among Koreans.Five data sources were utilized to select articles published until June 30, 2023.Results: This review analyzed 32 articles, including 23 cross-sectional studies, 7 case studies, and 2 clinical trials.Of which, 8 targeted adolescents, 22 targeted adults, 1 targeted both the demographics, and 1 targeted infants.In these studies, electronic cigarette use was associated with an increased risk of cardiovascular diseases and acute nicotine addiction, leading to cardiac arrest and mortality.Additionally, electronic cigarette use was linked to various health conditions, including periodontal disease, asthma, allergic rhinitis, atopic dermatitis, dyslipidemia, obesity, hypertriglyceridemia, and hyperuricemia.Moreover, it was associated with an elevated risk of depression, stress, and suicidal behavior.Conclusion: To establish consistent scientific evidence for the regulation of electronic cigarettes, multidisciplinary research on usage patterns, associations with various health conditions, and intervention strategies is imperative.
