Abstract

Background: Obesity is a state of excess adipose tissue mass. As adipose tissue accumulates in excess amounts a variety of adaptations/alterations in cardiorespiratory structure and function occur even in the absence of co-morbidities. The pulmonary disorders due to obesity results in increased mortality and morbidity. So, the study was to examine the effect of obesity on Peak Expiratory Flow Rate in different age groups.
Methods: 100 Healthy males with BMI ³ 30 kg/m2 were classified as obese and divided into three groups depending upon their age. 100 Healthy males with BMI of 18.50–24.99 kg/m2 were taken as controls. Anthropometric parameters were recorded and Body mass index was derived. Peak Expiratory Flow Rate (PEFR) were recorded on a computerized spirometer. ANOVA was used for multiple group comparisons and student’s t-test for two group’s comparison. Pearson’s correlation coefficient was used to measure the relationship between the measurements.
Results: In our study PEFR showed a significant decrease in obese subjects compared to non-obese subjects. There was statistically significant decrease in PEFR in obese subjects compared to non-obese subjects in all groups. Study shows the correlation between body mass index and PEFR and BMI which showed a statistically significant negative correlation.
Conclusion: In our study BMI had an inverse relationship with PEFR in obese when compared to the normal weight subjects. Thus it is evident from the present study that obesity significantly affects the pulmonary functions which may give rise to long term complications and may lead to early morbidity and mortality.
