International Journal of Integrative Medical Sciences. 2019 Feb; 6(2): 780-7842394-41372394-6318http://imsear.searo.who.int/handle/123456789/203096Introduction: Obesity, waist-hip ratio, rather than Body Mass Index (BMI) explains large part of the variance in pulmonary gas exchange. Hence, present study will be taken up to study the correlation between BMR, and Peak Expiratory flow rate (PEFR) in healthy underweight, normal weight, and obese adults.Materials and Methods: The present cross section study conducted in the department of Physiology, Kurnool medical college, Kurnool, with randomly selected 100 health voluntaries from both the sexes of the age group 20-40 yrs. The height and weight were taken to calculated BMI and PEFR was recorded.Results: The mean PEFR values were significantly lower in obese group when compared to normal weight. BMI was significantly and negatively correlated with PEFR in both males and females.Conclusion: The isolated effects of obesity unassociated with other diseases must be identified and the analysis of those effects should be stratified so that obesity related dysfunction may be evaluated in detail.Body Mass IndexObesityandPeak Expiratory Flow Rate.Journal ArticleIndiaAssistant Professor, Physiology Kurnool Medical college, Kurnool, Rayalaseema, Andhra Pradesh, India.
