Anatomical Study of the Relationship between Hand Length and Foot Length as Predictors of Stature among Nigerian Youths

Anatomical Study of the Relationship between Hand Length and Foot Length as Predictors of Stature among Nigerian Youths

CHAPTER ONE

1.1 Background of the Study

Human body measurements, or anthropometry, provide useful data for health assessment and forensic identification. Among these, hand length and foot length are reliable indicators of overall body stature (Krishan & Sharma, 2007). These dimensions remain relatively stable even when other body parts are damaged, making them valuable in forensic investigations.

In clinical settings, estimating height from hand or foot measurements assists in assessing growth disorders and nutritional status. For instance, doctors can estimate a person’s height when direct measurement is impossible due to injury, deformity, or amputation. Since body proportions vary among ethnic groups, locally derived predictive models are necessary.

Nigeria’s population diversity makes it important to establish reference data specific to Nigerian youths. Understanding the relationship between hand length, foot length, and height can improve both forensic and clinical applications. Therefore, this study seeks to examine how these parameters correlate and to develop regression models for estimating stature in Nigerian youths.

1.2 Statement of the Problem

Height estimation is crucial in medical and forensic fields. However, many existing equations are based on data from non-African populations. These formulas may yield inaccurate results for Nigerians due to genetic and environmental differences. This study aims to bridge that gap by generating accurate local equations.

1.3 Aim and Objectives of the Study

The aim of this study is to determine the relationship between hand length, foot length, and stature among Nigerian youths.

The specific objectives are to:

1. Measure hand length, foot length, and standing height of participants.

2. Analyze correlations between hand and foot dimensions with stature.

3. Develop regression equations for predicting stature using hand and foot measurements.

1.4 Significance of the Study

The findings will be useful to forensic experts, anthropologists, and clinicians who rely on body measurements. It will also enhance local anthropometric databases and improve identification accuracy in forensic cases involving partial remains.

1.5 Scope of the Study

The study will involve healthy Nigerian youths aged 18–25 years. Participants with limb deformities or growth abnormalities will be excluded.

1.6 Operational Definition of Terms

• Anthropometry: The scientific measurement of body size and proportions.

• Hand Length: The linear distance from the wrist crease to the tip of the middle finger.

• Foot Length: The linear distance from the heel to the tip of the longest toe.
