Vaping during the COVID-19 lockdown period in Belgium

Impact of mandatory masking amid the COVID-19 pandemic on outdoor smoking: an interrupted time-series analysis of a 33-month unobtrusive observational study

Background

Mask-wearing in outdoor public places in Hong Kong was mandated on 29 July 2020, amid the COVID-19 pandemic. We aimed to evaluate the impact of mandatory masking with no exemption for smoking on outdoor smoking.

Methods

We conducted 253 unobtrusive observations at 10 outdoor smoking hotspots in 33 months from July 2019 to March 2022 and counted smokers and non-smoking pedestrians in fixed boundaries. We conducted interrupted time-series analyses on the monthly mean volume of smokers (persons per hour) using generalized linear models. The independent variables were as follows: time since the first observation, implementation of the mask regulation, time since the regulation, seasonality, and waves 1-5 outbreaks. We checked the robustness of the association using the daily mean volume of smokers as the dependent variable. Two sensitivity analyses were conducted to include the hotspot location or the number of all pedestrians as an offset.

Results

Monthly outdoor smoking decreased immediately after the regulation (incidence rate ratio [IRR]: 0.505, 95% confidence interval [CI]: 0.374 to 0.680, P < 0.001). Daily smoking analysis and the two sensitivity analyses supported the results. However, monthly outdoor smoking increased by 11% since the regulation (IRR: 1.110, 95% CI: 1.074 to 1.147, P < 0.001). An exception was observed at the most severe wave 5 outbreak when monthly outdoor smoking decreased (IRR: 0.415, 95% CI: 0.327 to 0.525, P < 0.001).

Conclusion

Outdoor smoking fell immediately after mandatory masking, rebounded to pre-pandemic levels, and decreased again at the most severe wave 5.

Impact of COVID-19 lockdown on smoking and vaping: systematic review and meta-analysis

OBJECTIVES

COVID-19 and the implementation of lockdowns have impacted daily lives worldwide. This systematic review and meta-analysis aimed to investigate the impact of lockdowns on the smoking and vaping behaviours of adults during the pandemic.

STUDY DESIGN

This was a systematic review and meta-analysis.

METHODS

A systematic literature search was conducted up to 28 April 2022 in the following databases: PubMed, Embase and Web of Science.

RESULTS

In total, 77 studies met the inclusion criteria for this review. In 34 studies, an increase in smoking behaviour was reported for the majority of participants; however, in 21 and 18 studies, 'no change' and 'decrease' in smoking were the predominant responses, respectively. The results from the meta-analysis, which examined the change in the number of cigarettes smoked per day, showed no difference between the pre- and post-lockdown periods: 0.81 weighted mean difference (95% confidence interval, -0.59 to 2.21). Regarding vaping, three of seven studies reported an increase in smoking for the majority of participants, whereas 'no change' and 'decrease' were the predominant answers in the other four studies.

CONCLUSIONS

The results show that lockdowns led most participants to increase smoking/vaping, whereas a decrease or cessation of smoking/vaping was only reported in the minority of participants. Attention should be given to the non-communicable diseases that could arise as a result of the increase in smoking/vaping during lockdowns, and further research in this area is needed.

E-Cigarette Users' Profiles and Their Association with Identified Impacts of COVID-19 on Vaping among Young Adults in Malaysia

Electronic cigarettes (ECs) users' profiles and behaviors during the COVID-19 pandemic remain unclear. This cross-sectional study aimed to explore Malaysian EC users' profiles and their associations with related behaviors during the pandemic. The EC users (N = 351) were recruited from an official national vape entity. Respondents were predominantly of Malay ethnicity (90.6%), aged 31 to 35 years (27.6%), males (97.7%), married (68.7%), from Malaysia's west region states (63.5%) and tertiary educated (69.2%). The majority (80.3%) were non-dual users, and most purchased their vaping products online (77.2%), liked that they can vape while working at home (83.8%) and vaped more because of boredom (55.3%), had low and moderate nicotine addiction levels (94.9%), had low motivation level to quit EC use (92.6%) and were more likely to perceive that vaping did not increase the chances of complications from COVID-19. Respondents with moderate to high addiction levels had twice the odds of checking on their current EC supplies, whilst respondents with low motivation to quit had higher odds of using their tank/pod until the last drop and distancing from others when vaping. EC users should be encouraged to quit EC use, especially during the COVID-19 pandemic.

The Impact of the COVID-19 Pandemic on Smoking, Vaping, and Smoking Cessation Services in the United Kingdom: A Qualitative Study

BACKGROUND

Existing evidence suggests that while the coronavirus disease 2019 (COVID-19) pandemic triggered quit attempts among many smokers, it led some to smoke more and others to relapse back to smoking. These diverse effects have the potential to have a long-term impact on individuals' smoking and vaping behaviors.

AIMS AND METHODS

This study explored the effect of COVID-19 on smokers and vapers, vape shops (VS), and stop smoking services (SSS). A total of 39 semi-structured interviews were conducted with stop-smoking practitioners, tobacco control leads, smokers and/or vapers, and vape shop owners. Interviews were transcribed verbatim and analyzed thematically.

RESULTS

Four themes were identified: Lockdown as a barrier to becoming or remaining smoke-free; COVID as a catalyst for quitting and remaining smoke-free; changes in vaping and challenges for vapers and VS; and changes and challenges for stop smoking support. Fear of COVID resulting in severe health implications for smokers facilitated behavior change; however, the boredom and monotony of lockdown and associated stress created difficulties in remaining a smoke free. Results showed that the enforced switch from face-to-face to the remote provision of SSS was beneficial for improving engagement, particularly for vulnerable groups such as pregnant women. Stop smoking professionals and vapers disagreed with the forced closure of VS because it created unnecessary difficulties for vapers to access supplies.

CONCLUSIONS

COVID-19 was both a barrier and facilitator for smoking cessation. Remote provision of SSS implemented due to lockdown was beneficial for hard-to-reach groups; services should look to incorporate these changes into day-to-day practice.

IMPLICATIONS

This study is one of the first to explore how the COVID-19 pandemic directly affected smokers, vapers, SSS, tobacco control leads, and VS. It provides evidence for the continued use of the remote provision of smoking cessation services to increase engagement among hard-to-reach groups and provides information on how pandemics can be a catalyst for health behavior change. This study is unique in that it incorporates the views of different stakeholders.

Changes in tobacco use at the early stage of the COVID-19 pandemic: Results of four cross-sectional surveys in Hong Kong

INTRODUCTION

Changes in tobacco use since the COVID-19 outbreak differed by countries and little is known about changes in the use of specific tobacco products.

METHODS

We analyzed data from four cross-sectional telephone/online surveys from April to June 2020 to investigate such changes since the 1st and 2nd wave outbreaks (February to April 2020) in Hong Kong. The respondents were 1595 adults (83.2% male) who used tobacco before the COVID-19 outbreak from our previous intervention study and surveys. We investigated the changes in tobacco use, intention to quit and quit attempts during the outbreak.

RESULTS

About two-thirds (65.3%) of respondents reported no change in overall tobacco use, while 23.1% used less (including cessation) and 11.6% used more, resulting in a net decrease of 11.5 percentage points. A greater net decrease was observed for cigarettes (14.3% points) than heated tobacco products (HTPs, 3.3% points) and electronic cigarettes (e-cigarettes, 2.5% points). Decreased use was mainly due to the more extended stay at home (63.2%), health considerations (52.6%) and mask-wearing (47.4%), while increased use was for passing time (75.0%) and releasing stress (46.4%). Eight percent of cigarette, HTP and e-cigarette users reported a higher intention to quit since the pandemic outbreak. Nineteen percent of tobacco users (176/948) attempted to quit during the pandemic. Only 2.9% (46/1569) were abstinent at the time of the survey.

CONCLUSIONS

Overall tobacco use decreased after the first two waves of the COVID-19 outbreak in Hong Kong. A greater proportion of cigarette users decreased use than HTP and e-cigarette users. Given the different methods used in the four surveys, future studies should aim for a large and representative sample.
