INTRODUCTION
The purpose of this study was to investigate the use of lung age to motivate a quit attempt among smokers presenting to a hospital pulmonary function testing (PFT) laboratory.
METHODS
Participants were randomized to receive a lung age-based motivational strategy (intervention group) versus standard care (control group). At 1 month, all participants were interviewed by telephone to determine whether they made a quit attempt.
RESULTS
A total of 67 participants were enrolled, and 51 completed the study. Baseline mean data included age = 52 years, 70% women, 40 pack-years of smoking, FEV(1) = 69% predicted, and lung age = 83 years. The quit attempt rates were not different between the intervention and control groups (32% vs. 24%, respectively, p = .59). There was a near significant interaction between lung age and intervention strategy (p = .089), with quit attempt rates among those with normal lung age of 18% in the intervention group versus 33% in the control group and among those with high (worse) lung age of 39% in the intervention group versus 17% in the control group; p = .38.
CONCLUSIONS
Using lung age to motivate smokers presenting to the PFT laboratory to quit may succeed in patients with high lung age but may undermine motivation in smokers with normal lung age. Further work is needed to refine the approach to smokers with normal lung age.
简介
本研究旨在调查使用肺龄来激励到医院肺功能检测（PFT）实验室就诊的吸烟者尝试戒烟。
方法
参与者被随机分配接受基于肺龄的激励策略（干预组）或标准护理（对照组）。在 1 个月时，所有参与者均通过电话进行访谈，以确定他们是否尝试戒烟。
结果
共纳入 67 名参与者，其中 51 名完成了研究。基线平均数据包括年龄为 52 岁，女性占 70%，吸烟 40 包年，FEV1 为预计值的 69%，肺龄为 83 岁。干预组和对照组的戒烟尝试率无差异（分别为 32%和 24%，p =.59）。肺龄和干预策略之间存在显著的交互作用（p =.089），在干预组中，肺龄正常的参与者的戒烟尝试率为 18%，而对照组为 33%；在干预组中，肺龄较高（较差）的参与者的戒烟尝试率为 39%，而对照组为 17%；p =.38。
结论
使用肺龄来激励到 PFT 实验室就诊的吸烟者戒烟可能对肺龄较高的患者有效，但可能会削弱肺龄正常的吸烟者的戒烟动机。需要进一步研究来完善针对肺龄正常的吸烟者的方法。
