Anxiety and depression in patients with asthma
2011
Aim: To study the existence of anxiety and depression in patients with asthma and chronic bronchitis.
Material and methods: Descriptive epidemiological population-based study (2009 European Health Survey for Spain). Study subjects were selected by means of probabilistic multistage sampling, with the first-stage units being census section, and the second-stage units, main family dwellings. Subjects aged 18 years and over were selected. We identified asthmatic and chronic bronchitis (CB) individuals through a specific questionnaire. We analyzed socio-demographic characteristics and health related variables, including health care services use and concomitant chronic diseases diagnosed such as anxiety and depression.
Results: From 19.598 subjects included in the study, 1.632 were classified as asthmatic (8.32%, CI 95% 7.93-8.71) and 1467 (7.48, CI 95% 7.11-7.85%) as CB. The overall prevalence of anxiety was 7.69% (95% CI: 7.38-8.04) among people with asthma and 6.96% (95% CI: 6.62-7.31) among people with CB, no significant differences between them, although there were differences between each of them with healthy individuals, where the prevalence was 4.38% (95% CI: 4.09-4.67). The overalls prevalence of depression was 7.43% (95% CI: 6.18-8.67) among asthmatics and 9.93% (95% CI: 8.30-11.56) in those with CB, no significant differences between them, although there were differences between each of them with healthy individuals, where the prevalence was 4.57% (95% CI 4.28-4.86).
Conclusions: Patients with asthma and CB have higher rates of anxiety and depression than healthy individuals. Doctors involved in the management of these processes should take account of these results to improve control of their patients.
