“…Another statistically significant positive correlation (p<0.05) was between PEFR and BMI. This finding is consistent with a previous study done on medical students in Karachi, Pakistan [ 18 ]. However, this association was found only in underweight and normal-weight people.…”

Obesity has been defined as the excessive deposition of fats on the body. It presents a very significant risk to humanity, with debilitating consequences for healthcare systems worldwide. It has multiple effects on the body, including grave consequences on the cardiovascular and respiratory systems. Our project explores the latter. There are multiple studies available in the scientific literature that attempt to explain this phenomenon, all with limited success and conflicting results. This cross-sectional exploration of the topic was done on medical undergraduates to pick up on any correlations between peak expiratory flow rate (PEFR) and the markers of obesity (body mass index (BMI), waist circumference (WC), hip circumference (HC), and waist to hip ratio (WHR)). In general, we found that male participants had sizably higher PEFR values than females (r=0.540, p<0.01). Appropriate BMI is mandatory for the physiologic functioning of the human body. This work also statistically demonstrates a negative overall correlation between lung health and various parameters of obesity. Our work suggests a positive correlation between WHR and PEFR (r=0.325, p<0.01), BMI and PEFR (r=0.573, p=0.02), along with weight and PEFR (r=0.464, p<0.01). Maintaining a BMI and WHR in the normal range is essential for optimal physiological functioning and physical well-being.

“…Our study findings are similar to the findings reported by Chandra Selvi et al 17 in children and Ashraf et al in medical students. 18 However, this finding is contradictory to the previous findings which demonstrated that increased BMI correlates positively with a reduced PEFR rate compared to their peers during childhood, young children who are overweight or obese. 8,9 The study by Philominal SS et al 15 reported a significant difference in the PEFR rate between obese and normal.…”

BACKGROUNDThe aim of this study was to examine the difference in the measure of Peak Expiratory Flow Rate (PEFR) between overweight, obese and non-obese school going children in the age group of 8-13 years. MATERIALS AND METHODSA cross-sectional study was conducted involving 643 healthy school going children aged 8-13 years. The study was conducted in one secondary school selected in the urban area of Puducherry between August and September 2017. After baseline data collection including height and weight, BMI was calculated using the Quetelet index. The PEFR was measured using a mini-Wright Peak flow meter. For the study, the highest of the three measurements were recorded. RESULTSThe study included 643 healthy students, out of which 391 and 252 were boys and girls respectively. Out of 643 children, 590 were in the ideal weight range while 28 and 25 categorized as obese and overweight respectively. The prevalence of overweight and obesity among children in the age group of 8 to 13 years was 3.9% and 4.4% respectively. The present study showed that PEFR was significantly higher in the obese group (256.07±55.47 L/min), than overweight (252.00±51.24) and non-obese group (224.15±53.74, p<0.001). CONCLUSIONThe present study showed a significant difference in the PEFR rate between obese, overweight and normal groups where higher PEFR has been reported on obese than normal. Excess weight directly and positively affects the PEFR, while further investigations on the underlying mechanism is warranted. HOW TO CITE THIS ARTICLE:Babu RV, Devaraj VS, Harish VKS.

Background: The increasing number of overweight and obese individuals is a serious health problem worldwide. Growing evidence had clearly and consistently evidenced that obesity is an essential and direct predictor of respiratory function. Aim and objectives were to observe body mass index (BMI) based variations in respiratory parameter in overweight and obese individuals. Methods: The study was carried out on 320 (18-28 years) subjects in district Dehradun of Uttarakhand, India. Different anthropometric parameters and respiratory parameter was measured by proper procedures. Results: The anthropometric parameters weight and height were found statistically significant (p<0.05) among all subjects. BMI based and gender-based comparison of respiratory parameter were found statistically significant (p<0.05). The correlation of BMI with peak expiratory flow rate (PEFR) was found statistically very highly significant. The correlation coefficient (r) between BMI with PEFR was found= -0.6, denotes partial negative correlation.Conclusions: Our study concluded that with increased BMI the PEFR decreases, which signifies that there is broncho construction due to various mechanisms like direct action of adipose tissue on the air ways via a decrease in luminal diameter of the air way and an increase in the probability of airway collapse.
