ABSTRACT
Aim:To assess the peak expiratory
flow rates (PEFR) among healthy children aged 6 to 12 years
Study design: A cross-sectional study
Place and Duration: This Study
was conducted at Gambat
Medical College Khairpur Mir’s, Pakistan from April 2019 to March 2020.
Methodology: A study using a random sampling technique
was conducted in primary schools. Healthy school children of either gender ages
6 to 12 years were enrolled in the study. An EU scale peak flow meter measured
PEFR (60-800 l/min). While standing, their PEFR was determined. A total of
three readings were taken, with the highest value being recorded. SPSS version
21 was used for statistical analysis.
Results: Boys made up 56.15 percent (n=278) of the
495 participants. PEFR was measured at a minimum of 6 years old and a maximum
of 12 years old in both genders. Boys aged 6 to 12 years had a PEFR of 179.71 ±
30.67 (L/Min), whereas girls had a PEFR of 159.15 ± 25.77 (L/Min). There was no
discernible difference between genders and age categories (t=0.912, P=0.189).
Conclusion: Mean PEFR values may vary between gender and
age. PEFR results from this study can be utilized as a clinical reference for
children aged 6 to 12 years of age. Clinicians can use these PEFR values to
measure lung function and airway obstruction in this population subset.
