Description
Summary:Background Tobacco use remains a major public health problem especially in developing countries and emerging economies. The evidence about the effect of spirometry on smoking cessation is still controversial. The aim of this study was to determine whether a spirometry and lung age announcement were a motivator for smoking cessation. Methods We conducted a randomized controlled trial among patients who attended the smoking cessation clinic (SCC) at Fattouma Bourguiba University Hospital in Monastir, from June 2017 to February 2020. Participants were assigned into two groups, a control arm receiving standard program and intervention arm receiving standard program and lung age announcement. The primary outcome was the smoking cessation rates after one year of follow-up between the intervention arm and the control arm. Results A total of 500 patients were recruited and randomized with 250 patients in each group. At one-year endpoint, a total of 456 patients were reachable for assessment, 236 in control group and 220 in spirometry group. The loss rate was equal to 8.8% (54/500). Six months smoking rate was 78 (33.1%) in control group and 106 (48.0%) in intervention group (p = 0.002). One-year smoking cessation rate was higher in the intervention group than the control group (25.5% versus 16.5%), with a considerable statistical significance (p = 0.019). Spirometric lung age was significantly higher at paired comparison with chronologic age (58.81vs 46.54; p
