Smoking Status, Body Mass Index, Health-Related Quality of Life, and Acceptance of Life With Illness in Stable Outpatients With COPD.

Smoking and obesity are important factors related to the etiology and clinical features of chronic obstructive pulmonary disease (COPD). The aim of this study was to carry out deeper analyses of the links between smoking status and body mass index as well as of the links between individual dimensions of health-related quality of life (QoL) and acceptance of life with disease in patients with COPD. Information about BMI, smoking status, clinical features of COPD, a COPD assessment test, and airflow obstruction indicators were obtained from 105 outpatients attending a pulmonary clinic. Analysis of covariance demonstrated that the subgroups of patients distinguished based on smoking status and BMI differed significantly in severity of Cough, Dyspnea, Limitation of daily activities, Lack of self-confidence, and Quality of sleep, independently of sociodemographic factors and clinical features of COPD. The results of our study suggest a certain path of the potential effects of obesity and smoking status on QoL. Risky health behaviors, such as smoking and at-risk body mass, only affect some aspects of health-related QoL.

The role of psychological and medical variables in the process of adaptation to life with chronic illness in a group of COPD outpatients.

Many studies suggest that psychological factors play an important role in chronic diseases. This study aimed to describe the role of certain medical variables (airflow obstruction indicators), personal resources, coping strategies, and health-related quality of life (HRQoL) in the process of adaptation to chronic obstructive pulmonary disease (COPD). The Brief COPE inventory, the General Self-Efficacy Scale, COPD Assessment Test, and the Acceptance of Life with the Disease Scale were completed by 111 outpatients. Groups of patients distinguished based on degree of airflow obstruction did not differ in frequency of use of coping strategies, General Self-efficacy, HRQoL, or level of acceptance of life with the disease. Groups distinguished in terms of frequency of the strategies used differed in terms of indicators of airflow obstruction and acceptance of life with the disease. General Self-efficacy was correlated with active coping, use of emotional support, and planning. The best predictors of Acceptance of Life with the Disease were coping strategies, HRQoL, and General Self-efficacy. The obtained data indicated that psychological factors play an important role in adapting to life with illness. This study also found that self-efficacy is a very significant personal resource which future psychological interventions for COPD could focus on.
