Abstract
Introduction: The loss of body height in elders results in challenging threat for Forensic experts, Anatomists as well as Anthropologists by posing difficulties in applying equations based on estimates from adult population. Thus this study is conducted to evaluate the accuracy of body height equations from both foot lengths and Knee height measurements in subjects of all age.
Materials and methods: This evaluative study is conducted on 1000 (500 males and 500 females) asymptomatic, healthy adults, residing in Teerthanker Mahaveer University of cosmopolitan origin with age over 18 years old with no diagnosed history of knee arthropathy and spinal deformity and a written informed consent was taken from the subjects.
Results: The Linear regression equations for body height with knee height in males and females were found to be
B.H. = 75.62+1.79(KH); r2 =0.55, S.E.E. = 5.1 cms; B.H. =71.92+1.79(KH); r2 =0.33, S.E.E.= 5.7 cms respectively.
The Linear multiple regression equations for body height with knee height and age in males and females were found to be
B.H.=81.790+1.73(K.H.)-0.15(Age in years); R2= 0.566, M.S.E.= 25.86
B.H. = 74.137+1.78(K.H.)-0.06(Age in years); R2= 0.333, M.S.E. = 33.44 respectively.
Conclusion: Knee height is the best predictor of Body height alone as well as inclusion of age as a predictor variable shows improved R2* values in both the sexes along with lowest S.E.E.* values with Simple linear regression and with multiple linear regression showed decreased values of M.S.E.* than both foot lengths in both the sexes.
