“…Among all the pulmonary function test parameters Peak expiratory flow rate (PEFR) directly indicate the nutritional status which is also an easy and non-invasive method for estimating the lung function in children. [6] PEFR increases progressively with age, weight, height and more so with height in both sexes. For a given age, weight & height, boys have higher PEFR than girls.…”

Background: The predictive normal value of peak expiratory flow rate (PEFR), in children, is correlated with height and other anthropometric measurements, however, it shows ethnic Differences. The present study was conducted to establish the normal value of PEFR in healthy school children and to know the effect of various anthropometric factors on PEFR. Methodology: This study was conducted among 2200 students to assess their Peak Expiratory Flow Rate (PEFR) using Mini-Wright peak flow meter. PEFR values correlated with age, gender and various anthropometric measurements. Results: Out of total 2200 students, 1122 were boys which accounted for 51%. Mean PEFR for boys was 282.53 L/min and for girls was 270/.79 L/min. In boys and girls PEFR value increase as the age advances. Multiple regression modeling with PEFR as dependent variable and MUAC, BMI, Age, CC, Height, Weight and BSA as independent variables shows that Height, Weight, BMI, BSA, Age and chest circumference are independently associated with PEFR value. However, MUAC is not independently associated with PEFR values. Conclusion: From this study we conclude that in children between 6 to 17 year of age group the PEFR value in higher in boys compared to girls at any age. Height has strongest association with PEFR then the other variables.

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. A study of the association of overweight and peak expiratory flow rate (PEFR) among children.

Objective: The primary aim of our study was to assess the variation of PEFR with BMI in normal medical students of Karachi, Pakistan.Design: Cross-sectional study.Setting: Medical students of Karachi Medical and Dental College.Participants: 138 non-smoker healthy medical students composed of 111 females and 27 males.Variable Parameters: They include mean age, body height and body weight and PEFR. They were marked separately for each gender. Results:The mean BMI in females was found out to be 18.54±2.10 corresponding with that of mean PEFR value 431.62±56.62 whereas in males the mean BMI was 25.07±2.96 corresponding with that of mean PEFR value 533.70±23.22. Also there is a statistically significant variation in PEFR with an increase in BMI. Conclusion:The study concludes that PEFR is affected positively by variation in BMI. Also young males have more BMI and PEFR values than their young female counterparts. A large sample size with accurate peak flow meter is required along with ethnic consideration of the study population for better and accurate results.
