Values of peak expiratory rate (PEFR), ECG and Haematological variables in 250
females at their reproductive ages, made up of 123 pregnant subjects and 127 nonpregnant
control groups, living and/or working in Kura local government area and its
environs were obtained.
Pearson’s correlation coefficient between PEFR and ages as well as ECG,
Haematological and other anthropometric measurements were calculated in both
groups.
Multiple regression analyses were made to obtain the best prediction formulae using
the measured variables in pregnant and non-pregnant groups. Furthermore, graphs
were plotted to show the variation of PEFR with age in the subjects and controls with
specific weights. Data for plotting the graphs were generated using the prediction
formulae generated from this study and other prediction formulae generated from
previous studies among Nigerians, whose best prediction formulae incorporated age
and height. The graph illustrated the limitations of applying formulae derived from a
different race, tribe and/or generation to an entirely different people with dissimilar
characteristics. This lends credence to the need to make use of recent generated
formulae for local predictions.
