Poor Lung Function of Industrial Workers of Bhutan: a retrospective study

Introduction: Occupational lung diseases are some of the common causes function impairment. Spirometry is a gold standard to determine and, diagnose obstructive and restrictive diseases. Therefore, this study aimed prevalence abnormal among employees different industries Bhutan. Methods: This retrospective was carried out by retrieving all spirometry findings demographic variables Bhutan from Software Respiratory Laboratory at Center for Research in Neuroscience (CRRN), Khesar Gyalpo University Medical Sciences (KGUSMB) . All these retrieved data were saved Microsoft Excel simple descriptive statistics used analyze expressed numbers, percentages, mean deviation. Results: results 3508 industrial obtained. The age 33.8years BMI 24.95 Kg/m2. Non-smokers comprised 79.9% (2804) total employees. Abnormal forced expiratory volume between 25% 75% vital capacity (FEF25%-75%), marker small airway disease, constituted 24.1% (846) Furthermore, 1.1% (39) had (FVC), 1.3% (46) presented 1 second (FEV1 ) 1.5% (53) showed reduced FEV1 /FVC. Conclusions: Small impairment workers indicating presence high occupational its early stage which may potentially become clinically apparent after long latency.
