Indian Journal of Chest Diseases & Allied Sciences. 2023 Mar; 65(1): 14-170377-9343http://imsear.searo.who.int/handle/123456789/221857Background and objective: Silicosis is one of the oldest occupational lung diseases. However, there are very few studies identifying the anthropometric variables associated with silicosis. The present study aimed at studying the association between body surface area (BSA), pulmonary function indices, and 6-minute walk distance (6MWD) in patients with silicosis. Materials and methods: The study was conducted on 102 male patients of silicosis. Height and weight were measured to calculate BSA. Spirometry and 6 minute-walk tests were performed. Data were analyzed using EPI info V 7 software. Student's t-test of significance (ANOVA) was applied to test the difference between means. Results: There are no significant changes found in the 6-minute walk distance with years of exposure and BSA. Statistically significant lower values of pulmonary function indices were observed in patients with BSA <1.6 sq m. Statistically significant higher values of forced expiratory volume in the first second and forced vital capacity were observed in patients with BSA >1.9 sq m in all categories of exposure. Conclusion: In conclusion, patients of silicosis with >1.9 sq m BSA had higher values of pulmonary function indices. Large body size may be of value in protection from developing occupational lung disease.Occupational lung diseasePneumoconiosisPulmonary function test6-minute walk testRelationship between Body Surface Area and Pulmonary Functions in Patients of SilicosisJournal ArticleIndiaDepartment of Physiology, ESIC Medical College & Hospital, Faridabad, Haryana, IndiaDepartment of Community Medicine, ESIC Medical College & Hospital, Faridabad, Haryana, IndiaDepartment of Physiology, Amrita School of Medicine, Faridabad, Haryana, IndiaDepartment of Pulmonary Medicine, ESIC Medical College & Hospital, Faridabad, Haryana, IndiaDepartment of Pathology, ESIC Medical College & Hospital, Faridabad, Haryana, India
