Human body composition as related to surface area

European Journal of Pediatrics

|December 1, 1980

Summary

Body composition changes during growth, with extracellular fluid decreasing as body cell mass increases. Growth cessation is linked to specific body cell mass thresholds in men and women, impacting metabolic rates.

Area of Science:

Human physiology
Body composition analysis

Background:

Extracellular fluid shows a linear relationship with body surface area in humans.
Body composition undergoes significant shifts during growth, affecting various physiological parameters.

Purpose of the Study:

To investigate the relationship between extracellular fluid and body surface area.
To define growth cessation points based on body cell mass and body surface area.
To analyze body composition differences between sexes and their implications.

Main Methods:

Measurements of total body potassium, thiosulfate space, and total body sodium.
Analysis of 24-hour urine creatinine values.
Assessment of basal metabolic rate.

Main Results:

Extracellular fluid fraction decreases as body cell mass, fat-free solids, and body fat increase during growth.
Growth cessation occurs at 22.5 kg/m2 body surface area in men and 16.9 kg/m2 in women.
Sex-specific ratios of non-muscle to muscle cell mass are established, with women having a proportion more favorable for reproduction.

Conclusions:

Body composition changes linearly with body surface area, with distinct growth cessation points for males and females.
The basal metabolic rate is dependent on non-muscle mass, while total energy change is linked to body cell mass.
Infant body composition reflects fetal characteristics, with low body fat and non-muscle cell mass relative to surface area.
