Height: Ulna Ratio-A Method of Stature Estimation Used in Comparing the Stature of Ikwerre and Kalabari Tribes in Rivers State, Nigeria
Journal Title: Scholars International Journal of Anatomy and Physiology - Year 2018, Vol 1, Issue 1
Abstract
Abstract:This study was aimed at comparing the height predicted from ulna lengths in the adults (aged between 20 to 50 years old) from the two different ethnic groups. Analysis of stature of 600 healthy males and 600 females from Ikwerre and Kalabari ethnic groups, both in Rivers State, Nigeria, Height was measured using a stadiometer, while ulna length was taken with a sliding verniercalliper. The measurements were recorded in centimetres to the nearest 0.1 cm. A multiplication factor i.e ratio of the stature to the respective physical measurements was then calculated for each measurement. The multiplication factors were multiplied with the ulna length to give the estimated value which correlated with the measured stature. The mean male Ikwerre stature was 173.1 while the female was 160.77. The mean stature for Kalabari male was 166.83, while the female was 158.83. Correlation coefficient in the study for Ikwerre males is 0.96 and females 0.997 I and that of the Kalabari males is 0.996 and females 0.996. Regression coefficient for Ikwerre males is 7.89 and females 6.48 and that of Kalabari males is 6.31 and female 6.15. The observed data was subjected to ‘z’ test for correlation coefficient. The value for ‘z’ test was found to be statistically not significant. It was concluded that ulna length can be used as a surrogate in measuring height. Also, there was no significant difference in the stature of the two different tribes. Keywords: Height, Ulna, Stature, Ikwerre and Kalabari.
