Prevalence of smoking in a psychiatric hospital and its relationship with respiratory symptoms and the prevalence of COPD.

Purpose: Psychiatric patients present an elevated rate of smoking, and the smoking habit is related to a high morbidity and mortality in this collective. The aim of this study was to determine the prevalence of smoking in patients admitted for psychiatric disorders and its relationship with respiratory disease, the prevalence of COPD, and alterations in the quality of life. Patients and methods: A cross-sectional, observational study was conducted and detailed information on smoking and respiratory symptomatology was obtained. The study participants underwent the following tests: spirometry with bronchodilator test, Fagerström test, determination of physical activity using the LCADL questionnaire, and evaluation of quality of life with the EuroQoL-5 Dimensions EQ-5D questionnaire. Results: Two hundred seventy-six patients (mean age 56.8 years) were included: 155 with schizophrenia (87.7% smokers), 46 with depressive or anxiety disorders (54.3% smokers), and 49 and 25 with intellectual disability and dementia (43.2% smokers), respectively. The mean Fagerström test score was 5.75 points. Smokers presented with cough (47.6%), expectoration (41.4%), and chronic bronchitis (36.6%). The prevalence of COPD in the total population was 28.9%. The EQ-5D and LCADL scores were better in smokers because of their younger age and lesser psychiatric involvement. A high prevalence of smoking was observed in the psychiatric population studied, and 28.9% were diagnosed with COPD. Conclusion: Smokers presented many more respiratory symptoms and chronic bronchitis but did not present a worse quality of life or physical activity due to their younger age and milder psychiatric involvement.
