Physical Activity in Promoting Smoking Cessation in African Americans

Using Physical Activity to Facilitate Smoking Cessation Among African American Adults

This randomized pilot clinical trial studies the use of physical activity in promoting the discontinuation of the habit of smoking (smoking cessation) in African Americans. Participating in physical activity during an actual smoking quit attempt may work better in helping African Americans stop smoking.

PRIMARY OBJECTIVES:

I. Evaluate the feasibility of a Smoking Cessation with Physical Activity (SCwPA) intervention among an African American (AA) church-based sample of adult current smokers.

II. Conduct post-intervention focus groups to obtain feedback from pilot participants regarding the acceptability of the SCwPA project design and procedures.

III. Examine how physical activity (PA) and the timing of PA initiation affects the mechanisms underlying cessation among an AA church-based sample of adult daily smokers who are attempting to quit.

OUTLINE: Participants are randomized to 1 of 3 arms.

ARM I (PRE-QUIT PHYSICAL ACTIVITY): Participants receive telephone-based cessation counseling over 15-20 minutes 1-2 weeks before assigned quit date and nicotine patch for 6 weeks. Beginning 2 weeks before the assigned quit date, participants receive a Walking Program guide and engage in the SCwPA comprising brisk, self-paced walking with a goal of 150 minutes of exercise activity per week for 5 weeks.

ARM II (QUIT DAY PHYSICAL ACTIVITY): Participants receive telephone-based cessation counseling over 15-20 minutes 1-2 weeks before assigned quit date and nicotine patch for 6 weeks. Beginning on the assigned quit date, participants receive a Walking Program guide and engage in the SCwPA comprising brisk, self-paced walking with a goal of 150 minutes of exercise per week for 5 weeks.

ARM III (NO PHYSICAL ACTIVITY): Participants quit smoking on an assigned date and receive telephone-based cessation counseling over 15-20 minutes 1-2 weeks before assigned quit date and nicotine patch for 6 weeks.
