Impact of COVID-19 pandemic on overall and exams-related energy drinks consumption among students of the University of Sarajevo, Bosnia and Herzegovina.

Background: A pilot study conducted in academic 2017/18 among undergraduates of the University of Sarajevo showed energy drinks to be most frequently consumed during academic activity, less frequently mixed with alcohol in leisure, and rarely in the sports activity. The aim of this study was to assess the impact of the COVID-19 pandemic on energy drinks consumption among undergraduates of the same University, with a focus on their consumption during exams. Study design: A cross-sectional study was conducted by an online questionnaire. Methods: The questionnaire, mainly based on the Consortium Nomisma-Areté questionnaire, was customized to compare energy drinks consumption before and during the COVID-19 pandemic, and distributed among students between July 26th, 2020 and April 3rd, 2021. Results: Out of 1,045 students who chose to participate in the study (participation rate of 14.7%), 653 students, mostly women, attending the lower study years, reported energy drinks consumption. Both be-fore and during pandemic, overall energy drinks consumption was most frequently reported as rare [281 (43.9%) before, 326 (51.2%) during the pandemic], and exams-related energy drinks consumption as once or twice a week [156 (43.8%) before, 130 (42.1%) during pandemic]. The pandemic increased the number of frequent consumers (consumption of 4-5 energy drinks per week) in both overall [35 (5.5%) before, 46 (7.2%) during pandemic] and exams-related energy drinks consumption [42 (11.8%) before, 48 (15.5%) during pandemic]. Study year (OR=0.842; 95% CI 0.77-0.921; p<0.001), being single and living alone [OR=0.512; 95% CI 0.296-0.883; p=0.016), or living with a partner and children [OR=0.377; 95% CI 0.168-0.847; p=0.018) were identified as negative independent predictors for exams-related energy drinks consumption, while being a regular smoker (OR=0.429; 95% CI 0.223-0.875; p=0.011) appeared its new negative independent predictor during pandemic. Conclusions: The pandemic seemed to decrease both the overall and exam-related energy drinks consumption among undergraduates of the University of Sarajevo with the exception of a portion of already frequent energy drinks consumers.

Impact of COVID-19 pandemic on patterns of cigarette, hookah and marijuana consumption among undergraduate students of University of Sarajevo Bosnia and Herzegovina: a repeated cross-sectional study.

Aim: The aim of the study was to assess the impact of COVID-19 pandemic on patterns of cigarette, hookah and marijuana consumption among undergraduate students of Bosnia and Herzegovina. Methods: The first part of the double cross-sectional study was conducted among undergraduate students of the University of Sarajevo from 22nd to 26th January 2020, prior to the first COVID-19 case in the country (study period 1), and the second part from March 25th to August 26th 2021, during the third wave of COVID-19 outbreak (study period 2). Results: The majority of the 1,230 respondents were women (N1 70.9%, N2 70.1%), pursuing medical sciences (N1 60.0%, N2 55.0%), in their 3rd year of study (N1 26.3%, N2 26.7%), and living in urban environment (N1 84.9%, N2 86.4%). Similar proportion of cigarette smokers (N1 38.5%, N2 39.2%), and smaller, similar portions of hookah smokers (N1 19.3%, N2 21.1%) were classified in both study periods, while the smallest portion of marijuana smokers (N2 8.0%) was classified during COVID-19. Similar number of cigarettes per day, types of cigarettes consumed and consumption frequency in the last 30 days, with the similar independent predictors of cigarette consumption (being woman and living in rural environment associated with decreased risk, and age older than 22 associated with increased risk) were identified both before and during COVID-19 pandemic. Compared to before COVID-19 pandemic, increased trends in intentions (73.6% vs. 81.2%) and attempts (51.9% vs. 75.1%) to smoking cessation among cigarette smokers, but decreased determination not to smoke in the coming year among cigarette non-smokers (N1 72.2%, N2 51.6%) and decreased awareness of smoking harmfulness among both cigarette smokers (N1 68.0%, N2 46.5%) and especially cigarette non-smokers (N1 60.9%, N2 22.9%) were seen during COVID-19 pandemic. Also, risky behavior among hookah smokers was evident during COVID-19 pandemic. Conclusions: COVID-19 pandemic seemed to positively affect intentions and attempts to smoking cessation among cigarette smokers while negatively affecting attitudes towards cigarette smoking among cigarette non-smokers.
