This study was conducted to investigate the prevalence of pulmonary problems, among a group of 1600 selected textile mill workers in the Yazd province. A standard questionnaire on respiratory symptoms was administered and forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were determined for each worker. The results obtained were as follow: Obstructive ventilatory defect 15 cases (0.9 percent), restrictive ventilatory defect 16 cases (1 percent), combined obstructive and restrictive ventilatory defect (Mix) 53 cases (3.3 percent) and normal 1516 cases (94.8 percent).
