Effect of particulate matter (PM 10) pollutant concentration on peak expiratory flow rate score in junior high school students
AbstractBackground Various pollutants especially particulate matter with
diameter of 10 micrometer or less (PM 10) reduce the function of
lung. However, its effect to peak expiratory flow rate (PEFR) as a
parameter of central airway resistance is still inconsistent.
Objective This study was designed to assess the impact of differ-
ent PM 10 concentration to PEFR score among junior high school
students who live in two areas.
Methods It was a descriptive analytical study with cross sectional
design to junior high school students who lived in areas with high
PM 10 i.e, Cililin sub district (252.63 mg/m 3 /h) and low PM 10 i.e.,
Paseh sub district (27.15 mg/m 3 /h). PEFR was measured by using
Mini Wright Peak Flow Meter and body weight by microtoire. Data
of indoor pollutants were collected from questionnaires.
Results There were 463 subjects, 242 students in Cililin and 221
students in Paseh, who fulfilled the inclusion criteria which were
aged 12 â€“15 years, living more than one years continuously within
radius of 5 km from the location of pollutant measurement, non
smokers, and considered â€œhealthâ€ according to history taking and
physical examination. The PEFR score in Cililin (305.9+57.9 l/min)
was significantly lower than that in Paseh (327.7+54.8 l/min (t=4.15;
Conclusion Although the influence of indoor pollutants especially
cooking stoves could not be ignored, the difference of PEFR score
in these two groups were possibly due to the different concentra-
tion of PM 10
