Body-height predictions with lower extremity length in the mentawai ethnic group

Abstract

Introduction: This study was aimed to determine the correlation between body-height with lower extremity length and to predict the formula for body-height prediction of the Mentawai ethnic group. Material and Methods: The research was conducted at several places on Sipora Island with a sample size of 201 persons and analyzed through a Spearman correlation test as well as simple and multiple linear regression analyses. Results: The simple linear equation for male upper leg was Y = 130.291 + 0.674 upper leg length (±7.496), female Y = 129.484 + 0.489 upper leg length (±4.522) and for male Lower leg was Y = 130.488 + 0.934 lower leg length (±4.520), female Y = 129.423 + 0.681 lower leg length (±3.590). The multiple linear regression equation for males was Y = 114.193 + 0.437 upper leg + 0.81 lower leg (±6.615) and for females was Y = 117.150 + 0.357 upper leg + 0.572 lower leg (±4.773). Discussion and Conclusion: The Mentawai ethnic adult aged male body height, upper leg length, and lower leg length were greater than in females. As well, there was a significant correlation between body height with upper leg length and lower leg length.The obtained regression equotions can be used in the future to predict Mentawai ethnic adult-aged male and female body-heigth.
