A comparative study of airway resistance, conductance and residual volume in first year MBBS day scholars and hostelites from rural areas of BMCRI
Journal Title: Medpulse International Journal of Physiology - Year 2018, Vol 6, Issue 1
Abstract
Background: Literature states that exposure to automobile pollution is a proposed marker for future development of acute or chronic respiratory disease. Hence the current study was undertaken with a view to investigate the effect of automobile pollution on pulmonary function parameters of First year MBBS day scholars. The potential health risks in First year MBBS day scholars can be minimised by early identification of abnormalities in Pulmonary Function Test parameters and periodic retesting can detect pulmonary disease in the earliest stages when corrective measures are more likely to be beneficial. Objectives: 1. To record airway resistance, conductance and residual volume in day scholars and hostelites from rural areas (population <20,000) of First year MBBS from Bangalore medical college and research institute. 2. To test the hypothesis that there is decline in above parameters in First year MBBS day scholars due to long term exposure to air pollutants after comparing 2 groups. Materials and Methods: This is a comparative study done in 100 First year MBBS students from BMCRI. Group A: 50 healthy non-smoking day scholars of First year MBBS residing in Bangalore for 5yrs or more. Group B: 50 healthy non-smoking hostelites of First year MBBS from rural areas (population <20,000) are included for the study. Pulmonary function test was carried out, parameters like FEV1, FVC, FEV1/FVC, PEFR, FEF25-75 were measured using MEC PFT and RAW and sGAW were measured using body plethysmograph in both the groups. Results: It was found that Group A showed significant decrement in pulmonary function parameters like FEV1, FEV1/FVC, PEFR, FEF25-75, sGAW and significant increase in RAW(p value < 0.001) in First year MBBS day scholars when compared with hostelites counterparts. Conclusion: Results of our study showed that obstructive type of pulmonary abnormality is observed in First year MBBS day scholars exposed to automobile pollution for longer duration.
