A Cross sectional Study on Estimation of Stature from Forearm length in the age group of 18 to 25 years in Telangana population

Abstract

A cross sectional study on correlation of the stature from forearm length was conducted in the population of Telangana region of India, A total of 150 members participated in the study among 75 males and 75 females in the age group of 18 to 25 years. The aim of the study is to estimate stature from a fragmentary body part forearm in the population of Telangana and to derive a separate regression equation for both right and left hand and for both male and female individuals. Measurement of the body part forearm length has taken as distance from the tip of the olecranon to proximal wrist crease in semi flexed posture measured by using vernier caliper. Statistical analysis was done by descriptive statistics like mean standard deviation, correlation coefficient and linear regression. P vale <0.05 was considered as statistical significant. The data was analyzed by using SPSS version 25 software. The formula for right forearm is y = 50.76 + 4.18 X, left forearm is y = 50.89 + 4.19 X for total study group. For male population the formula for right forearm is y = 67.80 + 3.62 X, left forearm is y = 72.84 + 11.19 X. For female population the formula for right forearm is Y = 68.45 + 8.13 X and for left forearm is Y = 64.88 + 3.60 X.We found highly significant correlation between the forearm length and height of the individual. We observed a separate regression equation for right and left hand in both male and female population yield better result. We also observed left forearm equation is more accurate than right forearm. The height of the individual is about 6.1 times of forearm length. Linear regression formula developed in our study group is more appropriate for Telangana population
