Peak expiratory flow rate nomogram in Libyan schoolchildren.
The study aimed to develop a peak expiratory flow rate nomogram for Libyan children. Of 900 children randomly selected from four Tripoli primary schools, 670 (330 girls and 340 boys) with age range 4.5-14.9 years, fulfilled the selection criteria. Peak expiratory flow rate (PEFR) was recorded in a standing position using a mini-Wright peak flow meter. Anthropometric measurements, weight, height, head circumference and mid-upper-arm circumference were recorded and surface area and body mass index were calculated. Our findings showed PEFR to be significantly related to height (r = 0.74), age (r = 0.70), surface area (r = 0.64) and weight (r = 0.62): P < 0.001. The PEFR nomogram in Libyan children differed from the British standard, which highlights the need for a local reference nomogram.
