This study has aimed to analyze the quality of life of asthmatic patients, evaluated by one generic and another specific instrument as well as to verify the correlations between them.
A cross-sectional, descriptive and observational study with 51 adult asthmatic subjects (26 men and 25 women) with a mean age of 54.46 years (SD 19.17 years), all recruited from the out-patient clinic of the University Hospital of Salamanca, Spain, from October 2008 to March 2009. A clinical evaluation was performed, this including the spirometry, a socio-demographical form and the application of the Spanish version of the World Health Organization Quality of Life (WHOQOL-BREF) and the Saint George Respiratory Questionnaire (SGRQ).
Age correlated inversely and significantly with all the WHOQOL-BREF domains and only with the activity domain of the SGRQ. The severity classification and forced expiratory volume (FEV1%pred) did not show any relationship with any of the domains of both instruments. The physical and psychic domains of the WHOQOL-BREF correlated inversely and significantly with all the SGRQ domains.
In spite of the lack of relation between asthma severity and the different domains of the WHOQOL-BREF, the instrument is sensitive to the age variable and two of its four domains have correlated with all of the SGRQ domains.
