Severe fatigue is highly prevalent in patients with asthma and moderately associated with dyspnea, asthma control, and asthma-related quality of life (QOL), a new study found. The retrospective cross-sectional study of outpatients with asthma upon referral to a chest physician assessed fatigue, lung function, asthma control, exercise capacity, and asthma-related QOL. Researchers found:
- 733 patients with asthma (mean age 47.4 ±16.3 years, 41% male) were eligible and analyzed.
- Severe fatigue was detected in 62.6% of patients.
- Fatigue was not related to airflow limitation but was moderately related to asthma control, asthma-related QOL, and dyspnea.
- In stepwise multiple regression analysis, 28.9% of variance in fatigue was explained by asthma control, dyspnea, and age.
