1

What is nutritional status?

Basically a measure of whether you are getting enough of the right nutrients. (a balance between nutrient intake and expenditure)

2

What does the ABCDE of nutritional assessment stand for?

A = Anthropometry
B = Biochemical
C = Clinical
D = Dietary evaluation
E = economical/social standing

3

Define the 'A' domain and LIST the various tests of it?

Antrhopometry refers to the study of measurements and proportions of the human body.

Common measurements of body weight/composition
BMI
Percentage age weight loss
Lean body mass
Waist circumference




4

How do you calculate BMI and what is the healthy range for adults in NZ?

Weight in kg/height in m squared.

Healthy range in NZ is between 19 - 25

5

When/who should BMI not be used for?

Shouldnt be used for athletes/some sports people eg rugby players who have a very large lean body mass.

It is also adjusted slightly for ethnicities eg pacific have larger values due to genetic body composition/bone structure whereas indian/asian have slightly smaller values

6

How do you calculate change in body weight? (% weight loss)

Usual weight - current weight x 100 /
usual weight

(in other words "what youve lost/what you are normally times 100")

7

What is your body weight composed of and what are the ideal percentages for men and women (adults)?

Body weight = body fat + lean tissue mass (including water)

Men - body fat should be between 12-20%
Women - body fat should be between 20-30%

8

What is a good way to measure body fat distribution? (in a general clinic)

Waist circumference (between bottom rib and top of hip bone) or more effectively the waist:hip ratio

9

what are the normal values for waist circumference and waist:hip measurements in adults?

Men = around 90cm and ratio around 1:1
Women = around 80cm and ratio 0.8:1

10

What are some examples of biochemical nutritional tests?

Blood test to measure serum albumin level - determines protein status as this is the main protein in the blood

Blood test to determine serum transferrin level - determines whether iron levels are high or low as it measures the iron carrying protein in the blood

11

What does the "C" domain refer to/ what kinds of tests does it involve?

The clinical domain refers to the subjective tests a doctor performs and not the concrete set objective tests that just give a measurement like the BMI does for example.

Examples of clinical assessment include:
Detect signs and symptoms of malnutrition just through basic question eg how is you appetite? have you lost any weight? tired/lots of energy?
Measuring cognitive ability/physiologic performance
Oral/dental health
Use of drugs/drug-nutrient interactions
grip test - test of lean body mass
patient history
GI symptoms - any abdo pain? nausea? vomitting? bowell movements?

12

What is involved in the "D" domain?

Analysis of food intake/consumption patterns most frequently through 24 hour recall.

Analysis of food security - do they have enough money to afford good nutrition?

Usage of supplements?
