INTRODUCTION : Quality of life (QoL) evaluation is a useful tool to measure outcomes
of tobacco smoking. Understanding the relationship between them is important to
improve motivation to smoking cessation and for treatment outcomes.

Objective: Assess association of cigarette smoking intensity with quality of life in
COPD patients.
METHODS : We enrolled a cross sectional study including 105 COPD patients in the
Functional Exploration department of Farhat Hached Hospital. Anthropometric and
clinical characteristics were assessed by a standard medical questionnaire. Tobacco
consumption was estimated in pack years. Life quality was assessed according to the
ST. GEORGE'S RESPIRATORY QUESTIONNAIRE (SGRQ). All subjects underwent the
spirometry with measurement of Forced expiratory volume in one second (FEV1%)
and Forced vital capacity (FVC %). COPD is confirmed when the ratio FEV1/FVC post
bronchodilator test <0.7.

RESULTATS : Mean age was 63.8 ± 10.3 years and 87.6% were males. Median smoking
intensity (pack-years) and FEV1 (L) were 51.5 [37; 70] and 1.24 [0.87; 1.61] respectively.
In this study, 1%, 71.4%, 22.9% and 4.8% of the patients had GOLD stages 1, 2, 3 and 4,
respectively. Mean SGRQ score was 35.3±12.7. A statistically significant correlation
between smoking intensity and SGRQ score was found (p= 0.032 and

r= 0.220).

CONCLUSION : Low QoL is associated with higher smoking intensity. This finding can
raise awareness of both smokers and clinicians to become more conscious of the
sub-clinical outcomes of tobacco smoking and to encourage smoking cessation
programs.
