Authors :
Obesity is a global health hazard. As standards of living are continuing to rise, weight gain and obesity are posing a growing threat to health in countries all over the world. These obese individuals are at increased risk of morbidity and mortality because of its relationship with various metabolic disorders. It is also known to cause alterations in pulmonary functions, so the present study was planned to assess the effect of obesity on pulmonary function tests in adult males and females. To investigate the relationship between body mass index (BMI) and forced expiratory volume in one second (FEV1), forced vital capacity (FVC), ratio between FEV1/FVC, and peak expiratory flow (PEF) among nonsmoking adult males and females. Data were collected from 247 of adult healthy subjects with range age 32.63, There were 112 males and 135 females subjects, was classified on the basis of sex specific BMI as normal weight, overweight, obese, and moderate obese groups. Pulmonary function test (PFT) and body mass index (BMI) were compared among sex and BMI groups. Subjects underwent spirometry tests according to American thoracic society standards with measurement of the following values, the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEF). We found no significant differences in FVC and PEF (p value ˃ 0.05) in comparison between the obese and non-obese subjects, but there were a significant FEV1and FEV1/FVC with increasing BMI for adult females. An increase in BMI had no significant effect on spirometric measurements in adult males. Mean FVC, FEV1, FEV1/FVC, and PEF were found a high significant differences (P- value ˂0.0001) between mean spirometric values of men and women for all range BMI overweight, obese, and moderate obese.
