ABSTRACT
The authors evaluated the respiratory symptoms and pulmonary function test results (forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1], and ratio of FEV1 to FVC [FEV1%]) of female residents of the critically polluted industrial estate of Vapi, Gujarat (state), India, and compared these with control information derived from a village 20 km away. The authors categorized the studied residents as living in Vapi, in town, or in villages proximal to the Gujarat Industrial Development Corporation; living 2 to 3 km away from Vapi; living 3 to 5 km away from Vapi; and being in the control group. The authors found no significant association between respiratory symptoms and pulmonary function among Vapi residents. However, the obstructive type of abnormality was most predominant and significantly different among Vapi residents. The restrictive type was highly prevalent among residents living 2 to 3 km away from Vapi compared with the control group. These results suggest significant respiratory morbidity among residents that was associated with age and distance from the development corporation.
