Values of peak expiratory flow rate (PEF), ECG and Hematological variables in 250 females at their reproductive ages, made up of 123 pregnant subjects and 127 non-pregnant control group, living and/or working in kura local government area and its environs were obtained. Pearsons correlation coefficient between PEF and ages as well as ECG, Hematological and other anthropometric measurements were calculated in both groups.Multiple regression analyses were made to obtain the best prediction formula using the measured variables in pregnant and non-pregnant groups.
