8 Which anthropometric index to use? Depends on target groupDepends on what you want to measureFor children <5 years of age:Nutritional problemIndexChronic malnutrition (stunting)Height-for-ageAcute malnutrition (wasting)Weight-for-heightAny protein-energy malnutrition (underweight)Weight-for-age

10 Acute and chronic protein-energy malnutrition What are the characteristics of acute malnutrition?ChronicWhat are the characteristics of chronic malnutrition?
11 Acute and chronic protein-energy malnutrition Acute shortage of foodProduces recent rapid weight lossResults in wastingIs reversibleMeasured by weight-for-heightAdults can become wastedIs most important type in emergenciesChronicChronic shortage of nutrients or presence of multiple infectionsOccurs over a long periodResults in stuntingIn kids > 2 years, may be irreversibleMeasured by height-for-ageAdults cannot become stuntedIs very common in stable populations
12 Acute and chronic protein-energy malnutrition Both type of malnutrition can have serious consequences.
13 Anthropometry in adults Body mass index (BMI)Is ratio of weight and height: Weight (kgs)(Height [m]) 2Single cut-off points for all ages:BMICategory of Nutritional Status< 16.0Severe MalnutritionModerate MalnutritionMild Malnutrition18.5 – 24.9Normal Nutrition Status> 25Overweight
14 Why is it important how well we measure? Accurate data is needed to correctly classify nutritional status of individualsNeed correct classification of individuals to measure nutritional status in populationsWe use population assessments to make important program decisions
15 Measuring height (children 24 months or older) 1. Measure height for children 24 months and older if they can stand unassisted.2. Measure child without shoes and wearing light clothing.3. Remove hair accessories that interfere with measurement.4. Position child with feet flat and together on the base of the board.5.

For some children this is not possible and only the heels and buttocks will touch the board.6 Shoulders level and eyes looking straight ahead.7. Headpiece firmly against top of the child’s head and firmly against the board.8. Read measurement to the nearest 0.1 cm.
23 How to measure length1. Measure length for children less than 24 months of age.2. Measure infant without shoes and wearing light underclothing or clean diaper.3. Remove hair accessories that interfere with measurement4. Lay child on his back in the center of the measuring surface.5. Assistant cups the ears to hold the infant’s head so the infant is looking upward and the crown of the head is against the headpiece.6. Bring knees together, extend both legs and bring movable foot piece to rest against heels.7. Read measurement to the nearest 0.1 cm.
