Spirometry Evaluation of Asymptomatic Non-Smoking Overweight and Obese Subjects
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 1
Abstract
Introduction: Obesity has a significant impact on the respiratory function. In this study, we attempt to find a relation between the body mass index (BMI) and spirometry findings in healthy, non-smoking adults from North Kerala. Materials and Methods: Totally, 100 healthy non-smoking adults with BMI more than 25 were evaluated over 1 year with a detailed history, clinical examination, and spirometry. Data were evaluated using statistical software service provisioning system software version 21 for correlation between BMI and spirometry. Results: Out of 100 adults, 72 were males, and 28 were females. 63 adults were overweight, 31 had mild obesity, and 6 had moderate obesity. In the overweight group, 48 had restrictive anomaly, 2 had mixed anomaly, and 13 was normal. In the mild obesity group, 24 had restrictive anomaly, 2 had mixed anomaly, and 5 had normal spirometry. In the moderate obesity group, 3 had restrictive anomaly, 1 had mixed anomaly, and 2 had normal spirometry. There was a significant association between abnormal spirometry and BMI in both the overweight and obese groups. We could not find a significant association between the BMI and degree of restriction in any of the groups. Conclusion: Overweight as well as obese adults had abnormal spirometry in our study. There was no correlation between the degree of obesity and spirometry values. Hence, we conclude that even a small reduction in weight can improve the pulmonary function.
