Peak expiratory flow rate of primary school children in high and low air pollution level areas

Abstract: Background Chronic inhalation of air pollutants may causebronchoconstriction, bronchiolitis, and edema of airway, thus alterlung volume. To measure the lung volume, a simple lung functiontest, the peak expiratory flow rate (PEFR), can provide a feature oflung volume in liters/minute.Objective The purpose of this study was to measure PEFR val-ues of primary school children in a high air pollution level area(Medan) and compare the results with the PEFR values of those ina low air pollution level area (Tebing Tin… Show more

“…This explanation is supported by the finding that PEF, which is a measure of airway obstruction, was significantly lower in children from Zabrze than in children from Gdynia. Previous studies have shown that PEF may decrease due to air pollution in asthmatic children [33], but a similar effect among healthy children was reported only in some studies [34] and not in others [35].…”

“…Bila dianalisa dan dibandingkan dengan persamaan prediksi nilai PEFR normal berdasarkan faktor jenis kelamin, usia, tinggi badan, dan berat badan pada anak-anak Thailand (Srisingh & Phuaksaman, 2021), sebanyak 53,75% siswa-siswi memiliki PEFR lebih rendah dari batas bawah nilai normal (80% nilai normal hasil prediksi) (Kovesi et al, 2012). Bila dibandingkan dengan hasil pemeriksaan lain di Indonesia, rata-rata pengukuran pada anak laki-laki dan anak perempuan juga cenderung lebih rendah dibandingkan hasil pengukuran pada anak di Tebing Tinggi dan Medan (Tabel 7) (Hasibuan et al, 2003). Perbedaan pada hasil pengukuran dapat disebabkan oleh adanya variasi pada ras, genetik, geografik, etnis, serta umur (Srisingh & Phuaksaman, 2021).…”
