Peak expiratory flow rate was measured in 1500 rural Nigerian children using the mini-1-Wright's Peak Flow Meta Their ages ranged from 5-16years (mean SD: 10.0(5.-1) years for boys and 11.2(3.2) years/or girls). The mean (SD) values for PEFR were 350.4(52. 2) Ll111in for boys and 300. 0(60. 3) Limin for girls. The predicted data derived from the prediction formula for Caucasians was significantly higher (PLO. 001) than the observed values of the same age group. PEFR showed significant correlation with many constitutional variables. A positive correlation observed age and PEFR suggests that in Nigerians, a fal1 in PEFR will occur only after the age at which maximum PEFR is attained A combination o/age and height gave the regression equation with the least standard error of estimate for predicting PEFR in both sexes.
