Depressive symptoms among cigarette smokers and non-smokers during the first wave of COVID-19 pandemic: Preliminary findings from Bangladeshi male university students

University students may be particularly vulnerable to develop mental disorders, including depression, due to sudden and unexpected changes in their daily life during the COVID-19 pandemic. The present study aimed to assess depression among male smokers and non-smokers university students during the first wave of COVID-19 in Bangladesh. A web-based cross-sectional survey was conducted among 444 university male students using convenient and snowball sampling with a 1:1 ratio of male smokers and non-smokers from July to October, 2020. The prevalence estimates of moderate to severe depression were 53.6 % and 22.1 %, respectively among male smokers and non-smokers with an overall prevalence rate of 37.9 %. The participants who smoked cigarette were 4.05 times more likely to have depression compared to those who did not smoke (AOR = 4.05; 95 % CI = 2.60–6.30, p < 0.001). The following factors were found to be associated with depression: being smokers, having family members who lost jobs due to the impact of COVID-19, and having food scarcity due to COVID-19. The findings suggest mental health awareness and psychosocial support programs with a special focus on quitting smoking behavior among university students.
