Short-term effects of announcing spirometric lung-age on smokers’ attitudes: results from a Tunisian real-life pilot study

Résumé fourni par la source

Background To determine the effects of informing smokers of their spirometric lung-age (SLA) on smoking cessation (SC) rates and tobacco consumption.Research Design and Methods An interventional study was conducted in real-life through a humanitarian event led by the Red Crescent on 9 January 2022, in Hammam-Sousse (Sousse, Tunisia). The study comprised four steps: i) Medical questionnaire (general questionnaire, Fagerström test for cigarette dependence, SC motivation questionnaire); ii) Measurement of spirometric data; iii) SLA estimation and its announcement to participants; and iv) Self-reported evaluation of smoking behavior three months later through telephonic recall. Smokers were divided into groups (nondependent vs. dependent groups and insufficient/moderate motivation vs. high/very high motivation groups) and categories (ceased smoking, reduced consumption, maintained stable or increased consumption).Results Fifty-two smokers were included (94% were males). Three months after the event, i) 9 (17%) smokers ceased smoking, ii) 39 (75%) smokers reduced their daily smoking consumption by 12 ± 8 cigarettes/day, and iii) 4 (8%) smokers maintained stable (n = 3) or increased (n = 1) consumption.Conclusions Informing smokers of their SLA led 92% of them to cease smoking or reduce their consumption. Announcing SLA could be an effective motivational tool and an easy-to-understand concept to help smokers cease their habit.
