| Summary: | Introduction
How e-cigarette use relates to changes in smoking status and
respiratory symptoms in the population remains controversial. The aim was to
study the association between e-cigarette use and, changes in smoking status and
changes in respiratory symptoms.
Methods
A prospective, population-based study of random samples of the population
(age 16–69 years) was performed within The Obstructive Lung Disease in
Northern Sweden (OLIN) study and West Sweden Asthma Study (WSAS). A
validated postal questionnaire containing identical questions was used in OLIN
and WSAS at baseline in 2006–2008 and at follow-up in 2016. In total, 17325
participated on both occasions. Questions about respiratory symptoms and tobacco
smoking were included in both surveys, while e-cigarette use was added in 2016.
Results
In 2016, 1.6% used e-cigarettes, and it was significantly more common
in persistent tobacco smokers (10.6%), than in those who quit smoking (2.1%),
started smoking (7.8%), or had relapsed into tobacco smoking at follow-up (6.4%)
(p<0.001). Among current smokers at baseline, tobacco smoking cessation was
less common in e-cigarette users than e-cigarette non-users (14.2% vs 47.6%,
p<0.001) and there was no association with a reduction in the number of tobacco
cigarettes smoked per day. Those who were persistent smokers reported increasing
respiratory symptoms. In contrast, the symptoms decreased among those who quit
tobacco smoking, but there was no significant difference in respiratory symptoms
between quitters with and without e-cigarette use.
Conclusions
E-cigarette use was associated with persistent tobacco smoking and
reporting respiratory symptoms. We found no association between e-cigarette use
and tobacco smoking cessation, reduction of number of tobacco cigarettes smoked
per day or reduction of respiratory symptoms. |
