  Purpose

Adult female smokers will participate in an exercise-aided smoking cessation program, and will then be randomized into one of four cessation maintenance conditions: (a) Exercise Maintenance only (b) Exercise Maintenance + Relapse Prevention Booklets(c) Relapse Prevention Booklets + Contact and (d) Contact Control. Primary follow-up outcome is smoking behaviour. Secondary outcomes include exercise behaviour, Physiological measures (body composition (Dual-emission X-ray absorptiometry; DXA), vascular health (stiffness, endothelial function, carotid plaque volume), physical fitness), and Psychological measures (self-regulatory cognitions related to exercise adherence [exercise, scheduling, barrier, relapse, and concurrent self-regulatory self-efficacy]).

The hypotheses detailed below are specific to the randomization of participants into the following 4 groups:

  1. Exercise Maintenance only
  2. Exercise Maintenance + Relapse Prevention Booklets
  3. Relapse Prevention Booklets + Contact
  4. Contact Control

Hypothesis 1: Compared to quitters in the contact control condition, quitters exposed to a home-based lifestyle exercise maintenance intervention (Exercise Maintenance only and Exercise Maintenance + Relapse Prevention Booklets) will demonstrate significantly greater exercise adherence and fitness levels, as well as significantly less weight gain and smoking relapse rates following exercise-aided smoking cessation program termination.

Hypothesis 2: Compared to quitters in the contact control condition, quitters exposed to relapse information only (Relapse Prevention Booklets + Contact) will experience significantly less smoking relapse following exercise-aided smoking cessation program termination.

Due to the novelty and exploratory nature of the respective prevention programs, no hypotheses are specified with respect to which prevention program (exercise maintenance or relapse prevention information) will be superior to the other, or whether the additive benefits (i.e., exercise maintenance plus relapse prevention information) will be superior to one prevention program alone.

Primary Outcome Measures:
  • Smoking Behaviour [ Time Frame: 56 weeks post participant start date ] [ Designated as safety issue: No ]
    Continuous smoking behaviour will be measured from week 4-week 14, week26, week 56 (one year following quit). Smoking behaviour will be measured via self-report, breath Carbon Monoxide less than 6 parts per million, saliva cotinine.


Secondary Outcome Measures:
  • Exercise Behaviour [ Time Frame: for 56 weeks post participant start ] [ Designated as safety issue: No ]
    Exercise behaviour will be measured via Actical accelerometer at baseline, week 14, week 26 and week 56.

Arms Assigned Interventions
Experimental: Exercise Maintenance

Randomization and Group-Mediated Cognitive Behavioural therapy (GMCB) sessions will begin on week 8 of the program. Topics of self-regulation related to exercise (Social cognitive theory of self-regulation, Albert Bandura, 1991) will be discussed: monitoring, scheduling, goal setting, coping, overcoming barriers, rewards, social support.

Following the termination of the 14 week exercise aided smoking cessation program, trained exercise facilitators will deliver 15 minute biweekly (for the first month), monthly (for the next 2 months), and then bimonthly (for last 8 months) intervention strategies over the phone to continue to enhance the GMCB principles on how to maintain exercise behavior.

Behavioral: Exercise Behaviour Maintenance
Following the termination of the 14 week exercise aided smoking cessation program, trained exercise facilitators will deliver 15 minute biweekly (for the first month), monthly (for the next 2 months), and then bimonthly (for last 8 months) phone calls to remind the participants of the self-regulatory skills they learned during group discussion.
Other Name: Physical Activity
Experimental: Ex. Maintenance + relapse prevention

The same topics of self-regulation related to exercise maintenance(Social cognitive theory of self-regulation, Albert Bandura, 1991) will be discussed: monitoring, scheduling, goal setting, coping, overcoming barriers, rewards, social support.

Following the termination of the 14 week exercise aided smoking cessation program, trained exercise facilitators will deliver 15 minute biweekly (for the first month), monthly (for the next 2 months), and then bimonthly (for last 8 months) intervention strategies over the phone to continue to enhance the Group-Mediated Cognitive Behavioural therapy (GMCB) principles on how to maintain exercise behavior.

Participants in this arm will also receive the Brandon et al. (2004) Forever Free smoking relapse prevention booklets.

Randomization and group discussion sessions will begin on week 8 of the program. Topics of women's health, unrelated to exercise will be discussed (control).
