Comparison of peak expiratory flow rate (PEFR) before and after physical exercise in obese and non-obese children
Keywords:
peak expiratory flow rate, obesity, physical exercise
Abstract
Background Obesity has been associated with respiratorycomplications and it is believed to reduce lung volume. Obesity
imposes additional stress on ventilation during exercise and
may even result in pulmonary function impairment. Exercise
induced-bronchospasm has also been found in obese children.
Lung function tests can be useful to confirm diagnosis, response
to therapy, or prediction of lung and respiratory diseases. The
peak flow meter is an inexpensive, practical way to measure lung
function, and can detect the early warning signs of a decrease in
lung function.
Objective To compare the peak expiratory flow rate (PEFR) before
and after physical exercise in obese and non-obese primary school
boys aged 6 to 12 years old.
Methods A quasi-experimental study using the one group pretest-
posttest design was performed on 30 obese children (BMI above
the 95<h percentile) and 30 non-obese children (BMI between
the 5<h - 85'h percentile) using a mini-Wright peak flow meter
to evaluate the PEFR before and after eight minutes of physical
exercise. Height, weight, body mass index, and physical status
were determined before testing.
Results The PEFR before and after exercise were 14.80 for obese
children and 9.76 for non-obese children. The mean value for
PEFR between obese and non-obese children was significantly
different (P<0.05).
Conclusion The PEFR for obese children is significantly lower
than non obese children even before physical exercise.
