Assessment of the Relationship between Hand Length and Stature among Undergraduate Students

CHAPTER ONE

1.1 Background of the Study

Stature estimation plays a major role in forensic science, anthropology, and biometric identification. It helps identify individuals when complete bodies are not available. Among the many body measurements used for this purpose, hand length has shown a strong and consistent relationship with height (Krishan & Sharma, 2016).

The hand is one of the most accessible and durable body parts. It often remains intact even after decomposition or injury, making it useful for forensic investigations. By measuring hand length, experts can estimate stature with reasonable accuracy. In addition, this relationship assists in ergonomics, sports science, and garment design because it reflects body proportion and growth patterns.

Every population exhibits unique physical characteristics influenced by genetics, environment, and nutrition. These differences mean that formulas developed in other countries cannot always predict stature accurately for Nigerians. Consequently, there is a strong need to develop local regression equations based on Nigerian populations (Akpan & Igiri, 2019).

In forensic practice, having reliable local models can improve identification accuracy after accidents, disasters, or criminal investigations. Similarly, health and fitness professionals can apply these findings to design tools and equipment that suit Nigerian body proportions. Therefore, this study seeks to explore how hand length correlates with stature among Nigerian undergraduates and to produce equations useful for both forensic and anthropometric work.

1.2 Statement of the Problem

Most available regression equations for predicting height come from studies on non-African populations. When applied to Nigerians, these equations often give inaccurate results. This creates problems in forensic identification and anthropological studies. Hence, it is important to establish a locally valid model that links hand length and stature among Nigerian youths.

1.3 Aim and Objectives of the Study

The aim of this study is to assess the relationship between hand length and stature among undergraduate students.

The specific objectives are to:

1. Measure hand length and stature among male and female students.

2. Determine the correlation between these two parameters.

3. Develop regression equations that estimate stature from hand length.

1.4 Significance of the Study

The results of this research will provide valuable information for forensic and biometric identification in Nigeria. Forensic experts will use the data to estimate stature from incomplete remains, while designers and ergonomists can apply the findings to improve the comfort and safety of tools, clothing, and workspaces. Moreover, the study will contribute to the growing database of human body measurements within African populations.

1.5 Scope of the Study

The study focuses on male and female undergraduate students aged 18–25 years in selected Nigerian universities. Researchers will use standard anthropometric instruments to collect accurate hand and height measurements. Data will then be analyzed statistically to identify correlations and develop predictive equations.

1.6 Operational Definition of Terms

• Stature: The natural standing height of an individual in an upright position.

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

• Regression Equation: A statistical formula that predicts one variable based on another.
