Asthma control assessed in the EGEA epidemiological survey and health-related quality of life. Respiratory medicine. 2012;106(6):820-8. DOI: 10.1016/j.rmed.2012.01.009http://hdl.handle.net/10230/25425BACKGROUND: The aims were to assess 1) the relationship of asthma control assessed by combining epidemiological survey questions and lung function to Health-Related Quality of Life (HRQL) and 2) whether individuals with controlled asthma reach similar generic HRQL levels as individuals without asthma. METHODS: The analysis included 584 individuals without asthma and 498 with asthma who participated in the follow-up of the Epidemiological study on Genetics and Environment of Asthma (EGEA). Asthma control was assessed from survey questions and lung function, closely adapted from the 2006-2009 Global Initiative for Asthma guidelines. The Asthma Quality of Life Questionnaire (AQLQ, scores range:1-7) and the generic SF-36 (scores range: 0-100) were used. RESULTS: Adjusted mean total AQLQ score decreased by 0.5 points for each asthma control steps (6.4, 5.9 and 5.4 for controlled, partly-controlled and uncontrolled asthma respectively, p < 0.0001). The differences in SF-36 scores between individuals with controlled asthma and those without asthma were minor and not significant for the PCS (-1, p = 0.09), borderline significant for the MCS (-1.6, p = 0.05) and small for the 8 domains (<5.1) although statistically significant for 4 domains. CONCLUSION: These results support the discriminative properties of the proposed asthma control grading system and its use in epidemiology.application/pdfeng© Elsevier This is the published version of an article http://dx.doi.org/10.1016/j.rmed.2012.01.009 that appeared in the journal Respiratory medicine.
