Background
Various aspects of lifestyle seem to change during confinement, particularly during the COVID-19 pandemic. The current study examines confinement’s effects on tobacco smoking habits (SH).
Methods
A survey was distributed among adults living in Jordan (age >18 years) of both genders during April-May of 2020, of which 1925 responded to the survey.
Results
The prevalence of smoking was 33.3%, 46.1%, and 21.1% for cigarettes (Cg), waterpipe (Wp), and E-cigarettes (ECg), respectively. Among the smokers, 38.5–45.8% reported a “no-change,” while 32.1–41.7% reported a “decrease” in SH during confinement. On the other hand, 18.0–22.1% reported an “increase” in the SH. However, concerning the factors that might affect SH, the results showed that age, gender, income, and job sector contribute to the observed changes.
Conclusions
Changes in the SH during COVID-19 have been reported in about 50% of participants who smoke tobacco, with a more reported decrease than increase in use. Studies and interventions are needed to confirm further and understand the current results and discourage smoking during the COVID-19 pandemic.
