Exercise interventions for smoking cessation.

BACKGROUND: Taking regular exercise may help people give up smoking by moderating nicotine withdrawal and cravings. OBJECTIVES: To determine whether exercise-based interventions alone or combined with a smoking cessation programme are more effective than a smoking cessation intervention alone. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group specialized register for studies including the terms 'exercise' or 'physical activity' in July 2004. In August 2004 we searched MEDLINE, EMBASE, PsycINFO, CINAHL, Dissertation Abstracts and SPORTDiscus. SELECTION CRITERIA: We included randomized trials which compared an exercise programme alone, or an exercise programme as an adjunct to a cessation programme, with a cessation programme, recruiting smokers or recent quitters, and with a follow up of six months or more. DATA COLLECTION AND ANALYSIS: We extracted data on study characteristics and smoking outcomes. Because of differences in studies we summarized the results narratively, making no attempt at meta-analysis. MAIN RESULTS: We identified 11 trials, six of which had fewer than 25 people in each treatment arm. They varied in the timing and intensity of the smoking cessation and exercise programmes. Three studies showed significantly higher abstinence rates in a physically active group versus a control group at end of treatment. One of these studies also showed a benefit for exercise versus control on abstinence at both the three month and 12 month follow-up points. One study showed significantly higher abstinence rates for the exercise group versus a control group at the three month follow up but not at the end of treatment or at 12 month follow up. The other studies showed no significant effect for exercise on abstinence. AUTHORS' CONCLUSIONS: Only one of the 11 trials offered evidence for exercise aiding smoking cessation. All but one of the other trials were too small to conclude that the intervention was ineffective, or included an exercise intervention which was insufficiently intense to achieve the desired level of exercise. Trials are needed with larger sample sizes, sufficiently intense exercise interventions, equal contact control conditions and measures of exercise adherence.

Increase in common cold symptoms and mouth ulcers following smoking cessation.

OBJECTIVE: To examine changes in reports of common cold symptoms and mouth ulcers following smoking cessation. It was hypothesised that reports of these symptoms would increase on stopping smoking. DESIGN: Smokers were assessed one week before stopping smoking (baseline), then after one, two, and six weeks of smoking abstinence. PARTICIPANTS: 174 smokers attending a seven week smoking cessation programme combining behavioural support with nicotine patches. MAIN OUTCOME MEASURES: Self reports of cold symptoms, mouth ulcers, and smoking abstinence (validated using expired carbon monoxide) were recorded on each measurement occasion. RESULTS: Following one, two, and six weeks of smoking abstinence 73.0% (127/174), 57.5% (100/174), and 44.8% (78/174) of the participants, respectively, maintained continuous abstinence and provided reports of cold symptoms and mouth ulcers. For those abstinent from smoking for six weeks, relative to baseline, a significant increase in reports of the number of cold symptoms was observed following one and two weeks of smoking abstinence (p = 0.009 and p = 0.038, respectively) and an increase in reports of mouth ulcers after one and two weeks of abstinence (p = 0.004 and p = 0.008, respectively). Following one week of abstinence significant increases in reports of sore throat, coughing, deafness, and sneezing were observed (p = 0.049, p < 0.001, p< 0.039, and p < 0.003, respectively). CONCLUSIONS: This is the first study to systematically document significant increases in cold symptoms and mouth ulcers following smoking cessation. Smokers should be informed that they have an increased chance of experiencing these symptoms on stopping smoking. Being psychologically prepared for these effects may reduce their impact on the attempt to stop smoking.

Effect of a short bout of exercise on tobacco withdrawal symptoms and desire to smoke.

RATIONALE: Previous research suggests that a long bout of vigorous intensity exercise may reduce tobacco withdrawal symptoms and desire to smoke during abstinence. OBJECTIVE: In the present study, we investigated whether a short bout of moderate intensity exercise reduced desire to smoke and withdrawal symptoms in abstaining smokers. METHODS: Seventy-eight smokers attended the laboratory in the afternoon having not smoked since the previous evening. They rated their desire to smoke and withdrawal symptoms immediately before, during and after 10 min of moderate intensity exercise on a stationary cycle (experimental condition), or after waiting passively (control condition 1) or watching a video (control condition 2). RESULTS: Ratings of desire to smoke and withdrawal symptoms decreased more in the experimental group than in both control groups, which did not differ from each other. The effect was evident at all measurement points and was maintained for at least 10 min following exercise. CONCLUSION: A single bout of 10 min of moderate intensity exercise has a rapid and measurable effect on desire to smoke and tobacco withdrawal symptoms in abstaining smokers. Short bouts of exercise may be useful in helping to reduce desire to smoke and withdrawal symptoms during smoking cessation.
