Exercise Counseling to Enhance Smoking Cessation Outcomes: The Fit2Quit Randomized Controlled Trial
Regular exercise has been proposed as a potential smoking cessation aid.
This study aimed to determine the effects of an exercise counseling program on cigarette smoking abstinence at 24 weeks.
A parallel, two-arm, randomized controlled trial was conducted. Adult cigarette smokers (n = 906) who were insufficiently active and interested in quitting were randomized to receive the Fit2Quit intervention (10 exercise telephone counseling sessions over 6 months) plus usual care (behavioral counseling and nicotine replacement therapy) or usual care alone.
There were no significant group differences in 7-day point-prevalence and continuous abstinence at 6 months. The more intervention calls successfully delivered, the lower the probability of smoking (OR, 0.88; 95 % CI 0.81–0.97, p = 0.01) in the intervention group. A significant difference was observed for leisure time physical activity (difference = 219.11 MET-minutes/week; 95 % CI 52.65–385.58; p = 0.01).
Telephone-delivered exercise counseling may not be sufficient to improve smoking abstinence rates over and above existing smoking cessation services. (Australasian Clinical Trials Registry Number: ACTRN12609000637246.)
