Anthropometric Indicators of Nutrition

Anthropometric indicators are used to assess and determine nutritional status.

Anthropometry

Combining "anthropos" (human) and "metris" (measurement),
Sizes the physical characteristics of the human body

Nutritional Anthropometry

Measures physical dimensions (height, weight, circumference) to assess nutritional status
Determines body composition (fat and muscle tissue)
Is a sensitive method for determining nutritional status in nutritional epidemiology.

Assessment of Nutritional Status by Anthropometric Methods

Includes:
- Growth Measurements:
  - Height (lying or standing)
  - Weight
  - Head circumference
  - Knee height
  - Upper middle arm circumference
- Body Composition:
  - Determination of body fat mass
  - Skinfold thickness
  - Waist-to-hip ratio
  - Upper middle arm fat area
  - Determination of lean body mass

Indexes for Anthropometric Nutrition Indicator

Height by age
Body weight by age
Body weight by height
Head circumference by age
Waist/hip ratio, etc.

Anthropometric Indicators

Used in public health research and epidemiologic studies
Data on nutritional and health status of population is obtained from these measurements.

Growth and Development

Growth: Maturity in terms of size
Development: Changes in the working order of organs
Growth and development: Developments towards adulthood in size and working order of organs.

Positive Aspects of Anthropometric Measurements

Simple
Noninvasive
Reliable
Inexpensive
Easy to implement (with training)
Accurate and precise (with standardized techniques)
Expressed in numbers
Objective
Fast
Sensitive

Selection of the appropriate method in anthropometry depends on:

Risk groups
Age
Gender
Available resources

Standards/Reference Data

1st National, 2nd International
Longitudinal and cross-sectional data

Evaluation of Anthropometric Measurements

Percentiles: Percentage of observations below a certain value
Z-scores: Distance and direction of an observation from the mean value of a population
Percentiles are used in industrialized countries
Z-scores are recommended in developing countries

When Taking Anthropometric Measurements

Regularly check the accuracy of the measurement tools
Train the measurers
Use reference values/standards to verify the measurements
Identify any intersection points

Anthropometric Measurements for Nutritional Status

Height
Body weight
Skinfold thicknesses (e.g., triceps, biceps, suprailiac, subscapula)
Waist circumference
Hip circumference
Upper middle arm circumference
Head circumference
Chest circumference

Components of Body Weight

Protein (Muscle)
Total Fat
Bone Mineral Mass
Other parameters

Body Weight

A simple but important morphological indicator
Used to detect growth rate, obesity, and malnutrition
Clinically significant if more than 10% of body weight is lost in less than 6 months.

Body Weight by Age (Children)

Data for age ranges 0-5 years and 5.5-10 years are included in referenced tables

Z-Score Assessments (Weight-for-age GIRLS)

Z-scores assess weight relative to age-specific averages.
Standardized values for various growth and development assessment.

Height

Measures linear growth
Reflects physical development & skeletal structure.

Percentiles and Z-score assessments for Height

Data presented to categorize growth: stunted, short, normal, tall, very tall

Body Weight Measurements Procedures

Different procedures for adults and children (using different equipment) are stated.

Height-for-age Index

Indicates linear growth retardation
Short stature for age points towards stunted growth
Stunting is linked to chronic malnutrition

Body Mass Index (BMI)

Widely used to calculate ideal body weight recently.
Defines obesity and obesity risk at the population level.
Calculated as body weight (kg) divided by the square of height (m²).

BMI-Practical and Accurate Method for Assessing Body Weight

BMI Classification (WHO)

Classifies individuals over 19 years based on BMI values (kg/m²)
Provides categories for weight assessment

BMI in Children

Uses regional and international standards
Also uses percentiles and standard deviation scores (Z-scores) for assessment.

Head Circumference

Primarily measured in 0–3-year-old children to assess brain development and potential anomalies.
In older children, measurement may be necessary if a problem is suspected or no previous measurement exists.

Waist Circumference

Measures abdominal fat distribution & poor health.
Measurement procedure outlines a standard (standing upright, arms beside, feet together).

Waist Circumference Risks (Men & Women)

High waist circumference in both men and women indicates an increased risk of obesity complications and mortality

Hip Circumference/Waist-to-Hip Ratio

Hip circumference measurement and the waist-to-hip ratio indicate fat storage.
Waist/hip ratios above specific thresholds for men and women suggest increased obesity-related health risks.

Neck Circumference

Measures neck size as an indicator of abdominal obesity
Circumferences above specific thresholds for men and women suggest higher risk.

Skinfold Thickness

Triceps and subscapular measurements determine total body fat percentage.
Skinfold calipers are used in the measurements

Turkey Health Surveys, 2022

Show data pertaining to height and weight, by sex and age (self-reported); various charts showing survey data for obesity trends over time within Turkey,
Includes reference data tables and graphs on national anthropometric surveys of Turkey

International Comparison of Obese or Pre-obese Status, 2021

Charts showing percentile data on obesity and pre-obesity status of individuals age 15 years and over in different countries across the world
