Preventing Postpartum Relapse to Smoking Using Yoga and Cognitive Behavioral Therapy: A Randomized Pilot Study

• smoking abstinence by CO testing
  

• smoking abstinence by self-report
  

Many women quit smoking during pregnancy, but postpartum relapse rates are high, approximately, 50-80% (Van't Hof, et al). The majority of women who quit smoking during pregnancy resume smoking within the first 3 months postpartum (McBride, et al). The environmental risks of tobacco smoke on the newborn child can lead to acute respiratory infections, bronchitis, pneumonia, and SIDS. Several studies have tried to identify reasons for the high rates of relapse. Postpartum relapse has been attributed to decreased self-efficacy, the lack of effective coping strategies to resist temptation to smoke, and weight concerns (McBride, et al). Addictive behaviors such as smoking are learned behavioral means of coping. By learning new rules for dealing with problems, a behavior can be modified or unlearned. Physical exercise, when combined with cognitive behavioral therapy (CBT) as a smoking cessation treatment, is useful in the maintenance of smoking cessation in women. Yoga, as a form of exercise, has been shown to promote the desire to stop smoking and enhance subjective well-being and mood. Though untested in postpartum relapse prevention, yoga practice, when coupled with CBT, may address both mood and physiologic postpartum sensations that may be associated with the prevention of smoking relapse. Women are more apt to decrease or even stop smoking during pregnancy, and if successful in sustaining cessation, are likely to live longer.

This randomized exploratory pilot study will use a controlled parallel group design using smoking cessation yoga intervention and cognitive behavioral therapy. The study will include a total of 30 participants aged 18-45 years. Smoking status will be identified by self-report and carbon monoxide testing at enrollment. At randomization and following time points, smoking status will be identified by self-report and confirmed by carbon monoxide testing.
