Background: Peak Expiratory Flow Rate (PEFR) recording
is an essential measure in the management and evaluation of
asthmatic children.It is helpful in monitoring disease progression
and response to treatment. The PEFR can be measured by a
simple instrument—peak expiratory flow meter.
Aims and Objectives: To construct nomogram of PEFR in healthy
rural school going children from Mandya district of Karnataka
state, India and to use these nomograms for comparison with
that of children with obstructive lung diseases for this region.
Material and Methods: The study was conducted on Healthy
rural school going children, both boys and girls between the age
group of 5-16 years. For the determination of PEFR we used Mini
Wright Peak Flow Meter. At three time measurement, the highest
value of PEFR was recorded. Formula for prediction of PEFR was
estimated by linear regression analysis after the correlation of
PEFR with age and height for both boys and girls.
Results: PEFR was measured in 1028 children aged 5 to 16 years
by using Wright’s mini peak flow meter. Prediction equations
were derived for PEFR with height in boys and girls. Normograms
were plotted based on the observed values of PEFR in the study
population. Significant linear correlation was seen of PEFR with
height in boys (p<0.001, r=0.7624) and in girls (p<0.001, r=0.8825).
Prediction equation for PEFR are -317.43 + 4.40 x height (cm) in
boys and – 321.21 + 4.25 x height (cm) in girls.
Conclusion: Reference values of PEFR are affected by regional,
environmental and anthropometric factors. Hence, it is necessary
to have regional reference values for children. Among different
factors affecting PEFR, height correlates better with PEFR than
weight and sex. Hence nomograms constructed can be used for
this region. |
