Vape Knowledge Among Dental Students in Karachi

Abstract

Objective: To investigate the knowledge, perceptions, and associated factors influencing Vape (E-cigarette) use among dental students in Karachi, Pakistan.

Methodology: A cross-sectional survey was conducted from April 2023 to July 2023 at two dental colleges in Karachi after obtaining ethical approval. A total of 200 dental students, selected through convenience sampling, participated in the study. A modified version of a pre-validated questionnaire was administered, covering demographics, knowledge, e-cigarette use, and perceptions. Data were analyzed using IBM SPSS software version 22, with the chi-square test used to explore associations, considering a P value of <0.05 as statistically significant.

Results: Of the 200 participants, 53% (n=106) were female, and 57% (n=114) were aged 20-24 years. The study revealed that 36% (n=72) of dental students currently vape, while 79.5%(n=159) were knowledgeable about vaping. Social media played a significant role, influencing 58.5% (n=117) of students to start vaping. Approximately 45% (n=90) purchased vape products online, and 49% (n=98) believed that vaping could help in smoking cessation. However, 78% (n=156) of students acknowledged that vaping posed serious health risks.

Conclusion: A significant proportion of dental students in Karachi are aware of vaping, with a substantial number actively using e-cigarettes. Social media is a key driver of vaping behavior.
