Nutritional Status Assessment Flashcards
Name the 3 types of nutritional statuses.
- Undernutrition
- Well nourished
- Overnutrition
Define malnutrition
undernutrition + overnutrition
Describe the deficiency chain.
Deficiency -> declining nutrient stores -> abnormal functions in body -> physical signs and symptoms
Define primary deficiency.
Inadequate diet
Define secondary deficiency.
Problem inside body that causes deficiency
How can health providers examine the deficiency chain?
Primary: diet history
Secondary: health history
Declining nutrients + abnormal functions: lab tests
Physical S & S: physical examinations/anthropometric measures
What is the ABCDFG of Nutritional Status Assessment?
- Anthropometry
- Biochemical Lab tests
- Clinical Assessment
- Diet History
- Functional Assessment
- Genomics
What does anthropometry measure?
Height and weight
What does biochemical lab tests measure?
Nutrient and metabolite concentrations in blood, breath and urine
What does clinical assessment measure?
appearance and signs and symptoms
What does diet history measure?
- 3 or 7 day diet record
- 24 h food recall
What does functional assessment measure?
- muscle function
- lung function in chronic obstructive pulmonary diseases

Define lean tissues and its components.
Fat-free mass (water, muscle, bone)
Define adipose tissue.
Fatty mass
What is body composition for males?
- 15% fat
- 20% protein
- 60% h2o
- 5% minerals
What is body composition for females?
- 25% fat
- 15% protein

How do you convert feet to meters?
1) Divide inches / 12 = feet
2) Add to feet and divide by 3.28
How do you convert pounds to kg?
Pounds x 0.454 = kg
How do you convert kg to pounds?
kg x 2.2 = pounds
Where are minerals located in the body?
bones
Why do women have more fat?
to prepare for pregnancy
Name the 6 techniques for determining the amount of fat.
- Skinfold thickness
- BMI
- Underwater weighing
- Plethysmography
- Bioelectrical Impedance Analysis
- Dual X-Ray Absorptiometry
What is the BMI formula?
BMI = weight (in kg)/height (in m^2)
What does the BMI normagram explain?
lower bmis = bottom right
highest bmis = top left
What are the limitations of BMIs?
not a direct measure of fat, does not take into account muscle
Name the 5 classifications by BMI.
- Underweight
- Normal
- Overweight
- Obese
- Extremely Obese
What is the BMI of someone underweight?
< 18.5
What is the BMI of someone normal?
18-5-24.9
What is the BMI of someone overweight?
25-29.9
What is the BMI of someone obese class I?
30.0-34.9
What is the BMI of someone obese class II?
35.0-39.9
