THE EFFECTS OF ANNOUNCING TO CIGARETTE-SMOKERS
(CSS) THEIR SPIROMETRIC LUNG AGE (SLA) ON THEIR

C8 SMOKING ATTITUDES

Introduction. In exclusive CSs, the real merit and benefits of announcing their SLA is largely
controversial.

Aims. To evaluate the effects of telling a population of male exclusive CSs workers their SLA on their
smoking attitudes and to determine the clinical and spirometric profile of CSs who quit smoking.

Methods. An interventional study took place in a cable factory in Sousse (Tunisia). The intervention
included four steps: i) CSs attended a presentation raising the smoking hazards awareness; ii) CSs
performed a general questionnaire including the evaluation of their smoking habits and their nicotine
dependence level (Fagerström test); iii) height, weight, and spirometric data (FEV1, FEV6,
FEV1/FEV6) were noted, and SLA was calculated and announced to them; and iv) CSs were called
back (10 months later) to evaluate their smoking attitudes. CSs were divided into two groups
according to their spirometric pattern (no bronchial obstruction: FEV1/FEV6 ≥ 0.80; possible bronchial
obstruction: 0.70 ≤ FEV1/FEV6 0.80) and their nicotine dependence level
(dependent/nondependent), and into four groups according to their smoking attitudes (quit smoking,
stable, decrease or increase consumption).

Results. Among the 53 CSs, only 36 ones completed the four steps. Their mean±SD of chronological
age, SLA, and cigarettes consumption, were, 34±6 yrs, 39±11 yrs, and 14±9 pack-years. Ten months
after the intervention, four (11.1%), 19 (52.7%), 11 (30.5%) and 2 (5.5%) CSs quit smoking,
decreased their consumption by 7±4 cigarettes/day, kept a stable consumption, and increased their
consumption by 9±6 cigarettes/day. The four groups had similar chronological age, anthropometric
and spirometric data/patterns and Fagerström scores. However, compared to the subgroups of CSs
with stable or increased consumption, the quit smoking subgroup, had a significantly higher SLA
(34±8, 25±17, and 48±14 yrs). The dependent (n=30) and the nondependent (n=6) groups had similar
chronological ages, SLAs, spirometric data and included similar percentages of CSs with bronchial
obstruction.
Conclusion. Announcing the SLA had motivated 64% of CSs to quit smoking or to reduce their
smoking consumption. The profile of the quit smoking subgroup was characterized by a significantly
higher SLA.
