PURPOSE: Smoking is a major cause of cardiovascular and respiratory disease. Second hand smoking has been associated with respiratory symptoms. We studied the prevalence of chronic cough and sputum production as a surrogate of pulmonary abnormalities in patients with second hand smoking.
METHODS: One hundred thirty nine patients from a Veterans’ Administration Medical Center who underwent left ventricular ejection fraction measurements for clinical reasons, were evaluated for the presence of chronic cough and sputum production and history of second hand smoking, Using Fisher’s Exact and Chi Square Test, we evaluated any association between second hand smoking and chronic cough and sputum production.
RESULTS: Second hand smoking was significantly associated with chronic sputum production (second hand smoker (17 of 41, 41.5% vs 2 of 18, 11.19% in control OR: 5.7 CI 1.2-27.9, p=.0.02). There was a trend toward increase prevalence of cough in patient with second hand smoking (19 of 41, 46.3.5% vs 4 of 18, 12.2% in control group OR: 3.0 CI 0.85-10.8, p=.0.08).
CONCLUSION: Second hand smoking is associated with chronic cough and sputum production.
CLINICAL IMPLICATIONS: This study suggests that second hand smoking has deleterious effect on the lung function.
