Objective: To evaluate health-related quality of life in asthma patients treated at a referral center in southern Brazil, identifying differences between male and female patients, as well as to evaluate differences between the males and females in terms of asthma control, lung function, and nutritional status. Methods: This was a cross-sectional study involving patients ≥ 18 years of age treated at an asthma outpatient clinic. We evaluated clinical parameters, lung function, nutritional status, and quality of life. Results: A total of 198 patients completed the study. The mean age was 56.2 ± 14.8 years, and 81.8% were female. The proportion of patients with uncontrolled asthma was higher among females than among males (63.0% vs. 44.4%; p = 0.041). The body mass index (BMI) and percentage of body fat were higher in females than in males (30.2 ± 5.8 kg/m2 vs. 26.9 ± 4.5 kg/m2 and 37.4 ± 6.4% vs. 26.5 ± 7.4%; p = 0.002 and p < 0.001, respectively). Quality of life was lower in females than in males in the following domains: symptoms (3.8 ± 1.5 vs. 4.6 ± 1.7; p = 0.006); activity limitation (3.6 ± 1.3 vs. 4.4 ± 1.5; p = 0.001); emotional function (3.6 ± 1.9 vs. 4.5 ± 1.7; p = 0.014); and environmental stimuli (3.2 ± 1.6 vs. 4.3 ± 1.9; p = 0.001). Conclusions: Male asthma patients appear to fare better than do female asthma patients in terms of health-related quality of life, asthma control, BMI, percentage of body fat, and comorbidities.
