Abstract
Rationale: Respiratory symptom questionnaires (RSQ) are often used in assessing the health of individuals exposed to respiratory hazards. Methods: To investigate the validity of items fiom a self-administered standardized RSQ, we studied RSQ responses and results of spirometry and chest x-ray films (CXR) among 3376 underground coal miners who had participated in the NIOSH Enhanced Coal Workers' Health Surveillance Program fiom September 2005 to November 2007. Spirometry was conducted and interpreted in accordance with American Thoracic Society/European Respiratory Society guidelines. CXR were classified for coal workers' pneumoconiosis (CWP) using the International Labour Office system. For each symptom item, individuals who responded 'Yes' were compared to those who said 'No', assessing differences in mean spirometry values, the proportion of abnormal spirometry and CWP, using t-test and Chi-square statistics, respectively. Prevalence ratio regression analysis was performed to investigate associations, controlling for age, smoking, and body mass index. Results: Cough, phlegm, wheeze, shortness of breath (SoB), attacks of SoB with wheezing (SoBWZ), chest tightness (ChT), and doctor-confirmed emphysema (Em) were higWy associated (p
