Abstract

Introduction Vaping has continued to rise, besides smoking, among youth in Bangladesh in recent years. While there has been evidence of the impact of vaping on physical health, studies focusing on mental health specifically from the South Asian context are almost non-existent. Therefore, this study examines the association between vaping and a spectrum of mental health issues, such as psychological distress, depression, and anxiety, among university students in Bangladesh. Methods A cross-sectional study with undergraduate students, aged 18-25 years, from seven universities in Bangladesh, was conducted. Data were collected using a web-based questionnaire. Data on smoking, vaping, and dual use were collected. Psychological distress was measured by using the K10 scale, while the CES-D10 and GAD-7 scales assessed depression and anxiety, respectively. Univariate and multivariate logistic regression analyses determined the relevant associations. Adjusted Odds Ratios (AORs) and 95 Confidence Intervals (CIs) were reported. Results Of the 1615 study participants, males and females were distributed equally, and 54 were from two private universities. Findings revealed that one in six (15.4, n = 248) participants were currently vaping. Exclusive current smokers were 6.2, exclusive vape users were 6.5, and dual users were 8.9. Among vape users, the prevalence of psychological distress (80.5 vs. 76.6) and depression (63.8 vs. 60.8) was higher among dual users compared to current vape users; anxiety was similar (56.9 vs. 57.6) in both groups. After adjusting potential confounders, current vaping was associated with drinking alcohol (AOR 11.43, 95 CI 7.41�17.63) and used of recreational drugs (AOR 4.29, 95 CI 2.36�7.79) However, dual use was associated with higher depression (AOR 1.93; 95 CI 1.04�3.57) and without a preexisting mental health condition was associated with severe anxiety (AOR 2.00, 95 CI 1.25�3.20). Conclusion The study underscores a concerning impact on mental health amongst the young group of the population who were vaping, specifically among the dual users. Besides raising awareness, university-based tobacco cessation support and counselling should be considered a student well-being support strategy. © 2026 Sabrina et al.
