Study Notes

Anthropometry Measurements in Nutritional Assessment

Anthropometry measurements can identify mild, moderate, and severe states of malnutrition
They can identify individuals and populations at risk of malnutrition
They can evaluate changes in nutritional status over time
They can serve as proxy indicators of constraints to human welfare
They can monitor nutritional problems and evaluate the impact of interventions

Advantages of Anthropometry Measurements

Simple, safe, and non-invasive techniques are used
Inexpensive equipment is required, which is portable and durable
Relatively unskilled personnel can perform the measurement procedures with adequate training
Methods can be precise and accurate with standardized techniques and trained personnel
Retrospective information is generated on past long-term nutritional history
Mild to moderate undernutrition, as well as severe states of under- or overnutrition, can be identified
Changes in nutritional status over time and from one generation to the next can be evaluated
Screening tests can be devised to identify individuals at high risk to under- or overnutrition

Definition of Nutritional Anthropometry

Nutritional anthropometry involves measurements of the physical dimensions and gross composition of the human body at different age levels and degrees of nutrition
Measurements vary with age (and sometimes with sex and race) and degree of nutrition

Objectives of Anthropometric Measurements

To identify individuals and populations at risk of malnutrition
To evaluate changes in nutritional status over time
To monitor nutritional problems and evaluate the impact of interventions

Types of Anthropometric Measurements

Body size measurements: stature, weight, and head circumference
Body composition measurements: based on the "two component model" of fat mass and fat-free mass
Fat mass measurements: skinfold thickness measurements are used to estimate the size of the subcutaneous fat deposit
Fat distribution measurements: measurement of waist circumference is used to estimate the distribution of body fat
