In addition to the traditional biomedical parameters, quality of life (QoL) evaluation has found its well-deserved place in the overall assessment of patients with chronic obstructive pulmonary disease (COPD). The impact of socioeconomic status (SES) was rarely evaluated in QoL studies in such patients with no such studies having been conducted in Poland. The aim of our study was to compare QoL between COPD patients and the control group and to evaluate the impact of SES, selected demographic characteristics, smoking and bronchial tree obstruction on the QoL in COPD patients.
We enrolled 120 patients with COPD (98 men and 22 women; mean age: 62.3 years) with no comorbidities and 85 healthy individuals (39 men and 46 women; mean age: 56.0 years). All the COPD patients underwent spirometry. QoL was assessed with the SF-36 Health Survey and the St George's Respiratory Questionnaire. To assess SES, demographic variables and smoking we used a questionnaire of our own authorship.
COPD patients showed a significantly lower QoL compared to controls. Univariate analysis demonstrated effects of educational background, income, occupation, employment status and bronchial obstruction on the individual QoL domains. Multivariate regression analysis revealed that the sociodemographic factors significantly affecting the overall QoL included: present occupation, employment status, monthly income, educational background and total exposure to cigarette smoke. No effects of age, sex or smoking status on the QoL in COPD were shown.
The QoL in patients with COPD is affected by many factors. In addition to spirometric abnormalities the significant factors that modify QoL are: educational background, monthly income, present occupation and employment status, while sex, age and smoking status do not significantly affect QoL.
除了传统的生物医学参数外，生活质量（QoL）评估在慢性阻塞性肺疾病（COPD）患者的整体评估中也占据了应有的地位。社会经济地位（SES）的影响在这类患者的生活质量研究中很少被评估，波兰尚未开展过此类研究。我们研究的目的是比较COPD患者与对照组的生活质量，并评估社会经济地位、选定的人口统计学特征、吸烟和支气管树阻塞对COPD患者生活质量的影响。
我们纳入了120例无合并症的COPD患者（98例男性和22例女性；平均年龄：62.3岁）以及85名健康个体（39例男性和46例女性；平均年龄：56.0岁）。所有COPD患者均接受了肺活量测定。使用SF-36健康调查和圣乔治呼吸问卷评估生活质量。为了评估社会经济地位、人口统计学变量和吸烟情况，我们使用了自行编制的问卷。
与对照组相比，COPD患者的生活质量显著更低。单因素分析表明教育背景、收入、职业、就业状况和支气管阻塞对各个生活质量领域有影响。多因素回归分析显示，显著影响总体生活质量的社会人口学因素包括：当前职业、就业状况、月收入、教育背景和香烟烟雾总暴露量。未显示年龄、性别或吸烟状况对COPD患者生活质量有影响。
COPD患者的生活质量受多种因素影响。除了肺活量测定异常外，影响生活质量的重要因素还有：教育背景、月收入、当前职业和就业状况，而性别、年龄和吸烟状况对生活质量无显著影响。
