Abstract

Background: Obesity is one of the major health issues worldwide and so is in Saudi Arabia. It has enormously contributed to the increase in the incidence of diabetes and cardiopulmonary problems. However, very few studies are available where the effects of obesity on pulmonary functions have been investigated in young healthy Saudis. The aim of this study was to examine the lung function in the form of Peak Expiratory Flow Rate (PEFR) in healthy adults grouped into non-obese, pre-obese, and obese. Moreover, Study groups were analyzed for the PEFR changes in association with different obesity markers other than BMI. This was to identify the obesity markers that may have a better association with lung function impairment than Body mass index (BMI).

Methods: Young healthy students ages 18-19 years were selected for this study. Their height, weight, waist & hip circumference, and PEFR were measured. On the basis of BMI, subjects were divided into non-obese18.5-24.9, pre-obese 25-29.9, and obese > 30. All the analyses were performed using Graphpad Prism version 4 Mac (Graphpad software).

Results: Average values of all the morphometric parameters except height obtained from both pre-obese and obese subjects when compared with non-obese showed significantly higher values. Both the pre-obese and obese subjects showed a reduction in PEFR compared to the non-obese. However, this reduction was found significant only in obese subjects. Further, PEFR showed a significant negative correlation with BMI, Waist circumference (WC), waist-hip ratio (WHR), and body fat percentage.

Conclusion: Obesity produces significant deterioration in the PEFR in young healthy subjects and this deterioration is found to have a significant negative correlation with all the different obesity markers. This study also reveals that about 50% of young students belong to either pre-obese or obese groups and this rising trend needs to be addressed.
