Plain English Summary

Background and study aims
NHS smoking cessation treatment aims to help people to remain abstinent after a quit attempt, but even with the best available support as few as 22% are abstinent at 12 months. Studies have shown that during smoking abstinence, a short period of physical activity (e.g., a brisk walk, seated exercise) reduces cravings and withdrawal symptoms, and delays the time between smoking cigarettes. Physical activity has the potential to increase cessation rates. In this study we wish to examine whether physical activity enhances quit attempts and successful quitting among 'hard-to-reach' smokers from lower socio-economic groups.

Who can participate?
Heavy smokers (more than 15 cigarettes per day) aged 18 and over who wish to cut down but who have not yet quit.

What does the study involve?
Participants are randomly allocated to one of two groups. One group receives brief advice on cutting down. The other group receives brief advice and also a physical activity intervention (Health Trainer counselling, use of pedometers and guidance into free physical activity options). Both groups are offered support by the Plymouth NHS Stop Smoking Service for up to 6 weeks. The smoking status of all participants is assessed at 8 and 16 weeks after the start of the study, and at 4 weeks after any quit attempt. We also assess the number of quit attempts, quality of life, withdrawal symptoms, cravings, readiness to quit, confidence to quit and stay quit, use of NHS Stop Smoking Service; physical activity and weight. Taped interviews are conducted with GPs, stop smoking advisors and smokers to assess the feasibility and acceptability of the study procedures.

Study information

Scientific title

An exploratory trial to evaluate the effects of a physical activity intervention as a smoking cessation induction and cessation aid among the 'hard to reach'


EARS (Exercise Assisted Reduction then Stop)

Study hypothesis

Primary objective:
To develop a multi-component physical activity (PA) intervention aimed at helping smokers (not intending to quit in the next month), among 'hard to reach' groups, to cut down.

Secondary objectives:
1. To assess via interview the acceptability of such a PA intervention as an aid to cutting down, among 'hard to reach' smokers
2. To assess via interview the acceptability of recruitment, assessment and randomisation procedures within a pilot pragmatic randomised controlled trial to compare the effects of a PA intervention versus brief advice (usual care) on quitting, among 'hard to reach' smokers
3. To obtain an estimate of the intervention (PA versus brief advice) effect size, relative risk and its precision to inform sample size calculations for a fully powered trial, from a pilot randomised trial to assess carbon monoxide confirmed abstinence at 4 weeks post-quit date
4. To assess process measures at 4, 8 and 16 weeks post-baseline including:
4.1. Self-reported cigarettes smoked
4.2. Number of quit attempts
4.3. Self-reported quality of life
4.4. Mood and physical symptoms
4.5. Cravings
4.6. PA by self-report and accelerometer (in a sub-sample)
4.7. Pharmacological and behavioural support used
4.8. Weight
5. To estimate the resource use and costs associated with delivery of the intervention, and to pilot methods for determining future cost-effectiveness analyses

Smoking reduction and cessation


Brief advice:
Written and verbal information on NHS Stop Smoking Service (SSS) with information on the benefits of quitting and how to quit provided at baseline. Those expressing a desire to make a quit attempt will subsequently be referred to NHS SSS.

PA intervention:
Written and verbal information on NHS SSS with information on the benefits of quitting and how to quit provided at baseline. Smokers will select one of three strategies for smoking reduction and receive weekly support to attain this. Face to face physical activity support sessions will be conducted at weeks 1, 4, and 8 along with supportive phone calls in each intermediate week. The communications will involve tailored physical activity counselling, guidance on using a free pedometer to achieve SMART goals, and signposting to local exercise opportunities with subsidised access as required, with the aim of increasing the amount of regular physical activity completed by each participant for both implicit and explicit purposes as an aid to quit. Those expressing a desire to make a quit attempt will subsequently be referred to NHS SSS.

Added 14/07/2010:
Please note that this trial is recruiting only in Plymouth, specifically in Stonehouse and Devonport areas of the city, where smoking prevalence is more than twice the national, regional and citywide average.
