Clinical Trial Summary
This project aims to test the effectiveness of an integrated intervention of brief cessation
advice (AWARD) and simple physical exercise with Instant Messaging (IM) support compared with
control participants among current smokers who joined the contest.
Description:
Although smoking prevalence is decreasing in Hong Kong, it accounts for over 7,000 deaths per
year and a large amount of medical cost, long-term care, and productivity loss of US$ 688
million (0.6% Hong Kong GDP). Quitting is difficult because nicotine is highly addictive.
Long-term habitual tobacco smoking could foster a series of physical and psychological
dependence on nicotine, and thus induce cravings and nicotine withdrawal symptoms when
remaining abstinent.
In addition to pharmacotherapy and behavioral counseling, exercise has shown promising
effects on reducing craving, cigarette consumption, withdrawal symptoms, and increasing
intention and attempt to quit. Randomized trials on smoking cessation have shown that
vigorous or moderate exercise (including aerobics, brisk walking, and weightlifting)
increases tobacco abstinence. However, these exercise-based smoking cessation trials were
small-scaled with sample sizes ranging from 20 to 543, and mainly targeted the smokers who
were motivated to quit (active treatment seekers). Most (15/20) of the vigorous or moderate
exercises adopted in the smoking cessation trials required the participants to attend
multiple exercise sessions (at least weekly for 5 months) under supervision or
self-monitoring using equipment (e.g., pedometers) with a low proportion (<50%) of the
participants achieved targeted level of attendance and exercise. The effects were short-term
(end of treatment) and long-term (6 months or above) effects were uncertain, and cannot be
generated in smokers who had low motivation to quit.
Mobile health (mHealth) is now a part of the World Health Organization's (WHO) strategies on
combating smoking (http://www.who.int/tobacco/mhealth/en/) and has been used in many
countries given its low cost and popular use. Instant messaging (IM) applications (apps)
(e.g., WhatsApp, WeChat) are compatible with smartphones and allow sending interactive
messages such as text, photos, video, animation, and files. The widespread availability of IM
apps allows healthcare professionals to deliver health information and behavioral
interventions through messaging. The QTW Contest 2017 using chat-based psychosocial support
through IM apps effectively increased short-term (end of treatment, 3 months) and long-term
(6 months since intervention initiation) smoking abstinence.
The chat-based IM support has the potential to support the use of other treatment components.
The investigators aimed to test (1) the effectiveness of an integrated intervention of brief
cessation advice (AWARD), simple physical exercise with Instant Messaging (IM) support
compared with control participants among current smokers; (2) to explore participants'
experience and perceptions towards the intervention.
