Introduction: Peak Expiratory Flow Rate (PEFR) can be measured by cheap and portable instrument, peak flowmeter which is useful in detecting early asthmatic changes and monitoring the treatment response. Methods: This study was conducted on 1000 normal healthy children of nine to 14 years of age of either sex from various schools of Faridkot district in South West Punjab, India. Anthropometry was done and PEFR was measured using Mini Bell Peak Flow Meter. Linear regression analysis was done and normograms were constructed. Results: Linear regression equations were derived for PEFR with height, weight, BSA and BMI in boys and girls. The most significant correlation was seen with height (r = 0.527 in boys, r = 0.410 in girls) followed by body surface area (r = 0.506 in boys, r = 0.296 in girls). Body mass index had negative correlation (r = -0.200) with PEFR in girls. Nomograms were constructed on basis of linear regression equations of PEFR with height (-46.67 + 2.02 x height for boys, -12.64 + 1.50 x height for girls) and BSA (82.02 + 137.2 x BSA for boys, 96.61 + 88.11 x BSA for girls) Conclusion: There is need for nomogram for each region so that personal value of PEFR can be compared to normal reference population and also with predicted value from regression equation as PEFR varies from region to region. The nomograms and regression equations derived from this study can be useful for predicting normal values of PEFR of children of South West Punjab.

“…Several studies have been conducted in the past both in developed and developing countries including India and showed significant association between PEFR rate and age, sex, geographic area and anthropometric parameters including height, and weight. [10][11][12][13][14] Evidence has consistently showed that a significant regional, geographical and communities differences residing within the same country in terms of lung function parameters. In view of the above, the study has been conducted in Puducherry, given that to our knowledge none had previously attempted created nomograms in healthier population.…”

“…Southern studies reported a positive correlation between PEFR values with age, height, and weight in both sexes while the highest correlation was obtained for height. [10][11][12][13][14] Especially height influences the pulmonary functions amongst boys while age and weight for girls. However, in contrast, Pulickal 15 reported a linear but insignificant association between height and PEFR for both boys and girls.…”

BACKGROUNDThe aim of this study was to measure the peak expiratory flow rate (PEFR) among healthy school going children in 8-13 years age group. Further, the study aimed to examine the correlation between PEFR and anthropometric parameters including height, and weight stratified by age and sex, to create nomogram of PEFR and formulate regression formula for PEFR. MATERIALS AND METHODSA cross-sectional study was conducted on school going healthy children of 8-13 years age group at a selected school in Pondicherry using simple random sampling method. After baseline data collection, including height and weight, using standard method, PEFR was measured using mini-Wright peak flow meter. For the study, the highest of three measurements were recorded. RESULTSThe study included 643 healthy students, out of which 391 and 252 were boys and girls respectively. The findings showed that the age (β=7.83, p<0.001), height (β=0.84, p=0.036) and weight (β=0.79, p=0.015) are the significant predictors of PEFR values for girls while age (β=10.03, p<0.001) and height (β=1.36, p<0.001) but not weight (β=0.36, p=0.255) for boys. Nomograms were plotted based on the PEFR values observed in the study population. Predicted equations for PEFR accounting all the three-age, height and weight: PEFR (L/min) = -74.947 + 10.028 * Age (in years) + 1.361 * Height (in cm) + 0.358 * Weight (in Kg) in boys and PEFR (L/min) = -9.465 + 7.825 * Age (in years) + 0.840 * Height (in cm) + 0.797 * Weight (in Kg) in girls. CONCLUSIONThe present study showed a significant correlation between anthropometric parameters including weight and height with PEFR across age and sex among 8 to 13 years healthy school children. The equation would be helpful in evaluation of children with airway diseases.

“…The impact of ethnicity on PEFR (l/min) values was reported in a number of studies. Studies done by Singh HD et al, 14 swaminathan et al 3 Mahajan KK et al, 15 Ramachandra et al 16 and Malik SK et al 4 showed that south Indian children had lower PEFR values in comparison to north Indian children who in turn had lesser PEFR values when compared to their western counterparts as evidenced by studies done by Godfrey S et al, 9 Carson JWK et al, 17 Sanz et al 18 and Host A et al 11 In the present study, PEFR values were low in comparison to North Indian children. In contrast, the study conducted by Parmar et al 19 showed that PEFR values in healthy North Indian school children were similar to the findings from the western countries.…”

PEFR is a simple bedside tool to assess the degree of airway obstruction in asthmatic children. As it is influenced by age, anthropometric data, racial and ethnic differences, region specific nomograms have been advocated for use. This study has been undertaken with a view to establish reference values for PEFR and develop nomograms in Vizianagaram district. Material and Methods: The present study was undertaken at MIMS medical college, Vizianagaram. The main aim of this school based, cross-sectional, descriptive study was to establish standard nomograms of PEFR for healthy school going children between 5-15 years age group. A total of 2684 students were included in the study after meeting the inclusion criteria. PEFR values were recorded with mini-Wright peak flow meter. Body surface area and body mass index were calculated from height and weight. Statistical analysis was carried out using R version 3.4.2. Results: PEFR showed high positive correlation with respect to Height, Weight, Age, Body Surface area and moderate positive correlation with BMI. Separate regression models were developed for boys and girls. Conclusions: PEFR had positive correlation with height, age, weight, BMI and BSA.PEFR values of children in Vizianagaram district were lesser than those of other south Indian, north Indian and western children.
