Body Weight and Height Estimation from Second- and Fourth-Digits Length in Nigerian Children

Abstract

INTRODUCTION: Accurate body weight and height estimation is crucial for pediatric healthcare, nutrition assessment, and forensic investigations. Traditional methods often rely on direct measurements, which may not always be feasible, especially in emergency or resource-limited settings. The present study aimed to develop regression equations for predicting body weight and height from the length of the second and fourth digits in male and female children in Nigeria. 

METHODS: 318 male children and 336 female children between the ages of 7-15 years selected from three primary schools in Zaria local government, Kaduna state, Nigeria, were used in the study. The height of each participant was measured using a stadiometer, while body weight was measured using a bathroom scale. The length of the second digit (2D) and fourth digit (4D) of both hands in each participant was measured as the distance from the basal crease of the digit to the tip of the digit using a Vernier Calliper. 

RESULTS: The result revealed that female children have significantly (P<0.05) longer 2D and 4D in both hands when compared to male children. It also showed that the body weight and height of children can be significantly (P < 0.001) predicted from the lengths of right and left 2D and 4D. 

CONCLUSION: Body weight and height can be estimated from the lengths of the right and left 2D and 4D.
