Background/Aim. Chronic obstructive pulmonary disease (COPD) has a significant impact on quality of life of patients. We investigated which demographic and social characteristics can predict the global quality of life (QoL) of COPD patients. Methods. The patients (n = 288) were divided into three groups according to the stage of disease: Group I = stage 0-at risk; Group II = Stages I and II; Group III = stages III and IV. The patients fulfilled a questionnaire related to the demographic and social characteristics and the validated multidimensional questionnaire-Serbian version of the St. George's Respiratory Questionnaire (SGRQ). The Student's t test, χ² test, ANOVA, univariate and multivariate logistic regression tests were used for statistical analyses. Results. In the group I, prevailed the men, employed persons, with a moderate financial status and no family history of COPD. In the group II dominated women, pensioners, with a moderate financial status, duration of illness up to five years, and no family history of COPD. In the group III prevailed women, unemployed persons, a moderate financial status, COPD duration up to 5 years and Ključne reči: pluća, opstruktivne bolesti, hronične; kvalitet života; demografija; socijalno-ekonomski faktori; ankete i upitnici; srbija.
