This study showed that particulate air pollutants, or some metals contained in the particles, significantly affected the PEFR after adjusting for confounding factors as well as the genetic polymorphisms of GSTM1 and GSTT1.
The PeakLog is a lightweight, hand-held electronic device that measures PEFR. A built-in microchip records the date, time, and peak flow value each time the device is used.
However,pulmonary function screening of children in the school setting offers numerous benefits which include: 1) early identification and management of EIA, 2) facilitation of the child's participation in sport activities by using a FRAST or exercise-challenge and peak expiratory flow rate (PEFR) measurements to determine need for treatment, 3) provision of guidance for school personnel when a child has episodes of asthma at school, 4) education of families in monitoring respiratory status and initiating prompt treatment, and 5) collection of research data relative to EIA in the school setting.
The results shown that there is reduction in FVC%, PEFR, and MVV values and FEV1% and FEV1/FVC% ratio are increased in overweight and obese individuals as compared to non-obese individuals who are consistent with restrictive lung disease.
From the above table and by applying one-way ANOVA, it was found that FEV1% and PEFR (L/min) was statistically significant (F=39.94, p= <0.001).
In this study, 32.1% of participants had low PEFR (<80%).
Peak expiratory flow rate: Peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.
There was slight reduction in pulmonary function indices (FVC, [FEV.sub.1], and FEV1/FVC, PEFR and [FEF.sub.25%-75%]) as the duration of exposure increases.

The pulmonary function test, peak expiratory flow rate (PEFR) was performed to diagnose the presence of any lung related disorder.
