Anthropometric Measurements
Anthropometric measurements are quantitative measures of the size, mass, proportions, and composition of the human body. Within nutritional assessment they form one of the core domains of the ABCD framework (Anthropometric, Biochemical, Clinical, Dietary), providing non-invasive, low-cost indicators of body energy stores, growth, and changes in nutritional status over time.
Definition
Anthropometry is the systematic measurement of the physical dimensions and gross composition of the human body, including stature, weight, circumferences, skinfold thicknesses, and derived indices, used to assess nutritional status, growth, and body composition.
Scope
This area orients the reader to body-size and body-composition measurement as used in nutritional assessment. It groups the principal sub-topics: weight-for-height indices such as the body mass index, methods for estimating body composition, circumference measures and indicators of fat distribution, and the growth charts used to evaluate infants and children. It is a reference overview of how these measurements are defined and interpreted, not a protocol for clinical decision-making.
Sub-topics
Key concepts
- ABCD framework of nutritional assessment
- Weight-for-height indices
- Body composition (fat mass and fat-free mass)
- Fat distribution (central vs peripheral adiposity)
- Growth assessment in children
- Reference standards and measurement standardization
- Measurement reliability and reproducibility
Clinical relevance
Anthropometric indicators are widely used to screen for undernutrition, overweight, and obesity at individual and population levels, and to monitor change over time. They describe how nutritional status is measured and classified rather than prescribing treatment, and their interpretation depends on appropriate reference standards and standardized measurement technique.
Epidemiology
Because anthropometric measures are inexpensive and require minimal equipment, they are the backbone of nutritional surveillance worldwide, from national health surveys to community growth-monitoring programmes. Standardized indices and WHO reference standards allow comparison of nutritional status across populations and over time.
History
Anthropometry developed from nineteenth-century physical and forensic measurement into a tool of nutrition science during the twentieth century. Keys and colleagues (1972) consolidated the body mass index as the preferred weight-for-height index, while later work on body composition, fat distribution, and international growth references extended anthropometry into a standardized component of nutritional assessment.

Frequently asked questions
- What does 'anthropometric' mean in nutritional assessment?
- It refers to measurements of body size, mass, proportions, and composition - such as weight, height, circumferences, and skinfolds - that serve as non-invasive indicators of nutritional status.
- Why are anthropometric measurements used so widely?
- They are inexpensive, non-invasive, and require minimal equipment, which makes them practical for both individual assessment and large-scale nutritional surveillance.
