Slide 1 : Nutritional Anthropometric Techniques
Slide 2 : NUTRITIONAL ANTHROPOMETRY Measurements of variations of the physical dimensions and the gross composition of the human body at different ages and degrees of Nutrition.
Slide 3 : Anthropometric Measurements are of two types
Growth Measurements
Bogy Composition Measurements
Commonly used Anthropometric measurements
Body Weight
Height
Mid Upper Arm Circumference (MUAC)
Fat fold at Triceps
Head and Chest Circumference
Slide 4 : Advantages of Anthropometry The procedures are simple, safe, non-
invasive techniques and are applicable
to large sample sizes.
2. The equipment is inexpensive, portable,
durable and can be purchased locally.
3. Relatively unskilled personnel can
perform measurement procedures.
Slide 5 : Advantages of Anthropometry 4. The methods are standardized and are
precise and accurate.
5. The procedures are good in identifying
mild, moderate and severe forms of
malnutrition.
6. The procedures are useful in understanding
the changes in Nutritional Status over periods of time (Secular Trends).
Slide 6 : The common possible errors in the Nutritional Anthropometry are
Instrumental Errors
Technical Errors
Reading Errors
Recording Errors
Slide 7 : The Common Errors in taking the
Height
Subject not standing Straight
Head not in the FH Plane
Cross bar not touching the Vertex
Foot ware not removed
weight
Scale not calibrated to Zero
Subjects wearing heavy clothing
Subjects holding something
Slide 8 : The Common Errors in taking the
Mid Upper Arm Circumference
Subject not standing in the correct position
Tape too thick, stretched or creased
Incorrect arm
Mid arm point incorrectly marked
Arm not hanging loosely
Investigator not in the level of the measurement
Tape not at the mid point of the arm
Tape too tight / too loose
Slide 9 : The Common Errors in taking the
Fat fold at Triceps
Subject not standing in the correct position
Incorrect arm
Mid arm point incorrectly marked
Arm not hanging loosely
Finger thumb pinch taken very deep
Measurement taken too deep / too superficial
Jaws of the calipers not at the mid point
Investigator not in the level of the measurement
Late reading of the measurement
Slide 10 : Use of Anthropometric Measurements depends on two Factors …….
Accurate Age
Appropriate Normal Values for comparison (Standards / Reference values).
STANDARD reflects an optimal level of Growth suggesting that, all children have the potential to achieve that level.
REFERENCE is simply used for comparison.

BMI ? 5th - < 85th percentile : Normal
BMI ? 85th to < 95th percentile : Overweight
BMI ? 95th percentile : Obese School children and Adolescents (6-17 years) are classified in to different grades of nutritional status, using age/gender specific BMI centile values (Tim Cole) School children and Adolescents
Slide 20 : Adults are classified in to different Nutritional Grades
Based on BMI (WHO/Asia Pacific cut-off levels) as follows : ADULTS
Slide 21 : WHO Cut off levels to indicate a
abdominal obesity based on WC as
follows:
? 102 Cms for men
? 88 Cms for women
Asia Pacific cut off levels
? 90 Cms for men
? 80 Cms for women BMJ 1995; 311: 1401 IDF: 2005 Waist Circumference (Cm)
Slide 22 : WHO Cut off levels to indicate abdominal
obesity based on WHR as follows:
? 0.95 for men
? 0.80 for women
Asia Pacific regional cut off levels
? 0.90 for men
? 0.80 for women N Engl J Med 1999; 341: 427 IDF: 2005 Waist Hip Ratio (WHR)
