“…A few studies have attempted to compare the PEFR values of highlander and lowlander populations and found a significant rise in PEFR among high-altitude residents [17]. A number of studies have distinctly substantiated the effect of various anthropometric parameters like age, height, and weight on lung function in normal children [18 -20].…”

Context: Peak expiratory flow rate (PEFR) is an effort-dependent parameter, emerging from the large airways within about 100-120 msec of the start of forced expiration. It measures the degree of obstruction in the airways. A child from an asthmatic family, having significantly low PEFR values than its height and age matched peers, can be considered under impending asthma category. Aims: The present study was proposed to detect early stages of airway obstruction in school going children. Settings and Design: Observational study conceived in the department of Physiology, AIIMS, Jodhpur, Rajasthan. Methods and Material: Hundred students of age group 7-15 years participated in the study. A family history for presence/absence of asthmatic symptoms was taken from all subjects. After anthropometric examination, PEFR values were recorded in standing position, using the Mini Wright Peak Flow meter after demonstrating them the right procedure. Three measurements were taken and the highest reading was recorded. Statistical Analysis Used: Fisher’s exact test was done to calculate the two tailed ‘P’ value, Odd’s ratio and relative risk. Results: Thirty-one Percent children with family history of airway obstruction showed PEFR values below 80% of the predicted value, while 5.74% who were not having any family history of asthma, also showed values below 80% of the predicted value. With Fisher’s exact test, the two tailed ‘P’ value was 0.0155 (significant). Conclusion: The results of this study support the vital role of PEFR related to changes in airflow, which eventually can result in early identification of children with airway obstruction.

Objective:Spirometric evaluation of pulmonary function has been evolved as clinical tool in diagnosis, management, and follow-up of respiratory disorders. There are very few studies on normative reference values of pulmonary function parameters for adolescents from Tripura, a North-eastern state of India. The present study was aimed to evaluate pulmonary function and their predictors in male and female adolescents of Tripura.Materials and Methods:A total of 640 (320 from tribal and 320 non-tribal) healthy, non-smoking male and female school children (age 10-14 years) from four different districts of Tripura were randomly sampled for the study. The pulmonary function parameters analysed included forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow rate (PEFR), forced expiratory flow between 25% and 75% expired volume (FEF25-75%), ratio of FEV1/FVC and maximum voluntary ventilation (MVV).Results:The results revealed that body weight, body mass index (BMI), PEFR, FEF25-75% and MVV are significantly high among male tribal children in comparison to non-tribal children. Height, weight, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), PEFR and MVV were found to be significantly more in tribal girls. In case of adolescents from Tripura, most of the pulmonary function parameters correlated with anthropometric parameters of the subject like height, weight, BMI, WHR, and WHtR.Conclusion:From the present study, it can be concluded that both anthropometric and pulmonary function status of tribal and non-tribal adolescents from Tripura are comparable. The computed regression norms may be used to predict pulmonary function of adolescents from Tripura by using anthropometric indices.

Background: The Peak Expiratory Flow Rate (PEFR) is useful to screen and monitor the severity of asthma in children. Many studies have documented that age, height and weight are some of the main factors that affect the PEFR. Thus, the present study was done to find the PEFR values among the school children and to find the factors that influences the PEFR values in our geographical area.Methods: It was a cross sectional study conducted in school children belong the rural area of Kancheepuram district, Tamil Nadu, India. A total of 378 students of both the gender at the age group of 5-10 years were selected for the study. The PEFR was measured by making the participant seated comfortably. One peak flow meter was used for 25 children and mouthpiece was changed for each student.Results: The PEFR value among and male and female participants was analyzed statistically (Table 2). The mean value of male and female study population was 169.53±37.38 and 146.24±33.01 respectively. The difference in the mean values were statistically significant (p=0.001) and found to be high in male participants. The Pearson correlation r between PEFR with height is 0.463, thus showing a positive correlation with the p˂0.001 which is statistically significant. The Pearson correlation r between PEFR and chest circumference is 0.335 thus indicating a positive correlation between PEFR and chest circumference.Conclusions: From the present study, the normal values of PEFR has been deduced for the healthy school children in our geographical area. Further, it was found that the height and chest circumference are influencing factors for PEFR. Further regression equation has been derived that can help us to find the approximate PEFR values with the help of height and chest circumference of the children.
