Women who engage in higher levels of exercise while trying to quit smoking have been shown to be less likely to relapse and to sustain their smoking abstinence longer. This study sought to examine the benefits of exercise for improving smoking cessation among Black women.
We evaluated the feasibility of a 12-week smoking and exercise intervention, Quit and Fit, tailored for Black women. All participants (intervention and control) received 12 weeks of smoking cessation counseling via telephone and 9 weeks of nicotine lozenges. Participants who were randomly assigned to the intervention condition were also assigned to a 12-week exercise group.
Thirty-eight women were enrolled and 27 completed a 12-week follow-up assessment. Women from the intervention group were more likely to complete the 12-week follow-up assessment compared to participants in the control group (80% vs. 61%). Overall, 7 of the 38 participants (18%) were abstinent at 12 weeks (biochemically verified by expired carbon monoxide). Among the 25 women who completed the 12-week follow-up, abstinence was reported in 33% of the intervention group and 20% of the control group. Using an intent-to-treat approach, 25% of women in the intervention group were abstinent at 12 weeks (n = 5), compared to 11.1% for the control group (n = 2). These differences were not statistically significant.
The overall retention rate was 71% (27/38) at 12 weeks with higher among the intervention group (16/20; 80%) compared to the control group (11/18; 61%). The study demonstrates that it is feasible to retain African-American women in a short-term study of smoking cessation and exercise.
研究表明，在尝试戒烟的过程中，运动水平较高的女性复发的可能性较低，并且能够更长时间地保持吸烟戒断。本研究旨在探讨运动对改善黑人女性戒烟效果的益处。
我们评估了一种针对黑人女性的 12 周吸烟和运动干预计划（Quit and Fit）的可行性。所有参与者（干预组和对照组）都通过电话接受了 12 周的戒烟咨询，以及 9 周的尼古丁贴片治疗。随机分配到干预组的参与者还被分配到一个为期 12 周的运动小组。
共招募了 38 名女性，其中 27 名完成了 12 周的随访评估。与对照组相比，干预组的女性更有可能完成 12 周的随访评估（80%对 61%）。总体而言，38 名参与者中有 7 名（18%）在 12 周时达到了戒烟（通过呼出的一氧化碳含量的生物化学验证）。在完成 12 周随访的 25 名女性中，干预组的戒烟率为 33%，对照组为 20%。采用意向治疗方法，干预组 25%的女性在 12 周时达到了戒烟（n=5），而对照组为 11.1%（n=2）。这些差异没有统计学意义。
12 周时的总体保留率为 71%（27/38），其中干预组的保留率较高（16/20；80%），对照组的保留率较低（11/18；61%）。研究表明，在一项短期的戒烟和运动研究中，保留非洲裔美国女性是可行的。
