ABSTRACT
Objective: To assess the influence of BMI on the pulmonary functions of the employees and young people of Shaqra University, Shaqra.
Study Design: cross-sectional survey study
Place and Duration of Study: This study was conducted at the Department of Medicine, Colleges of Medicine, Shaqra University (SU), in Riyadh, Saudi Arabia, from September 2022 to February 2023.
Materials and Methods: A specified questionnaire assessed the medical history of the participants followed by spirometry according to the American Thoracic Society. ANOVA with Tukey’s post hoc test was used to assess any difference in BMI and lung metrics between various groups, and Spearman’s correlation coefficient was used to determine any relationship between BMI and lung metrics. A p-value of 0.05 was considered significant.
Results: Two hundred and twenty-nine (77.0%), 35 (12.0%), and 33 (11.0%) of the 297 participants were Saudis, South Asians, and Africans, respectively. Their mean age was 31.3± 10.2 years. Analyzing the effect of BMI on spirometry values showed that there is a significant negative correlation between BMI categories and the lung function parameters (FEV1, FVC, FEV6, FEF25-75%) except for FEV1/FVC and FEF25-75%/FVC.
Conclusion: The BMI is inversely related to lung function parameters and it entails to curtail the curse of obesity in our populations.
Key Words: Body mass index, lung function parameters, spirometry, obesity, healthy adults.
