ABSTRACT
Body mass index (BMI) is a quotient that has been in use since the mid-19th century, it is the calculation of weight divided by height, and it is universally expressed in kg/m2. Major BMI classifications are Underweight - BMI under 18.5 kg/m2, Normal weight - BMI between 18.5 to 24.9 kg/m2, Overweight – BMI between 25 to 29.9 kg/m2, Obesity – BMI greater than or equal to 30 kg/m2. Cardiopulmonary function indices include Forced vital capacity (FVC), Forced expiratory volume in 1sec (FEV1), Peak Expiratory Floe Rate (PEFR), Blood Pressure and Pulse Rate. The aim of this study was to determine if there is any correlation between Body Mass Index and Cardiopulmonary function indices in male subjects. A total of 20 male subjects within the age range of 18-25years, 5 subjects were used as Underweight, 5 subjects were used as Normal weight, 5 subjects were used as Overweight and 5 subjects were used as Obesity. The subjects were seated and asked to inhale fully then blow into a spirometer forcefully, They were instructed to take a deep breath, put the mouthpiece of the peak flow meter inside mouth between the upper and lower jaw, and expel the air forcefully in one blow, their blood pressure and pulse rate where measured using an electronic sphygmomanometer. The result showed no significant increase in peak expiratory flow rate, blood pressure and pulse, there was a significant increase in FVC values for overweight (2.48+0.21) and significant increase in FEV1 values for overweight (2.44+0.19) compared to the underweight. However, this result may not be regarded as enough evidence to conclude that body mass index has an effect on cardiopulmonary function indices.
