Abstract
The study presented the mathematical approach to determine the Peak expiratory flow rate of male bakers in Abeokuta, Ogun State, Nigeria with the relationship of the peak expiratory flow rate and the anthropometrical parameters. A total of One hundred and Eighty (180) individuals were investigated with ninety (90) bakers (study group) who are exposed to flour dust and ninety (90) control subjects. The entire subject both study and control group are male. Peak expiratory flow rate (PEFR) and anthropometrical parameters were measured using mini-Wright peak flow meter (PFM 20, OMRON) and Detecto PD300MDHR (Cardinal Scale manufacturing company USA) column scale respectively. PEFR measured were compared using T-test and regression analysis. A mathematical model was developed to determine the peak expiratory flow rate (PEFR) with four factors of body mass, height, age and year of exposure where applicable. The study showed that PEFR in bakers was 182.67 ± 16.34 L/min as against 287.67 ± 17.03 L/min for control group from the regression analysis. Similarly, the model revealed that baker has 182.69 L/min and 285.77 L/min for control group. The Study concluded that using the developed model will serve as a great importance to workers to determine the level of their health and subsequently prevent untimely death.
