A model for the estimation of height and body mass index from arm span and to determine the socio-demographic characteristics cross-sectional study of Bowen University Students

Arm span is the most reliable anthropometric measurement to predict the stature of an individual. Arm span, hand length, foot length, head circumference etc., have been proven to be useful to correctly estimate the height of a person. This study was intended to derive a model for the estimation of height and body mass index from arm span and also to determine the socio-demographics characteristics of the participants. Samples of 500 students in Bowen University were used for this research (250 males and females respectively) with varying ethnicity. Heights were measured accurately while Weight was taken using a standard calibrated weight scale; arm span measurement. Analyzed by Pearson’s correlation, the results analysis showed a significant effect of arm span on height on males, and a significant effect of height on BMI in both sexes. There is a significant effect of arm span on BMI on male and no significant effect in females; results from t- test indicated sexual dimorphism in height and arm span but not in BMI.
