Design and Development of Portable Body Composition Analyzer for Children

Area of Science:

• Biomedical Engineering
• Pediatric Health
• Body Composition Analysis

Background:

• Accurate body composition assessment is crucial for monitoring child health.
• Existing methods can be cumbersome or inaccessible for widespread pediatric use.

Purpose of the Study:

• To design and develop a portable body composition analyzer (BCA) for children.
• To validate the developed portable BCA against a commercial device (Tanita MC 980 MA).

Main Methods:

• Developed a portable BCA device measuring body weight, body fat (BF) %, total body water (TBW), fat-free mass (FFM), muscle mass (MM), and bone mass (BM).
• Validated the prototype with 200 healthy and obese children aged 8-12 years.
• Compared results with the Tanita MC 980 MA BCA device.

Main Results:

• The highest percentage differences were observed in body fat (50.39%) and body mass index (41.73 kg).
• Statistically significant differences were found in FFM (38.32 kg) and MM (37.89 kg).
• The prototype achieved an overall error of ±3% when validated against the Tanita MC 980 MA.

Conclusions:

• The developed portable BCA prototype demonstrates high accuracy and low standard error.
• This device has the potential to be a reliable tool for evaluating and tracking body composition in children.
