Week 13 - Anthropometrics Flashcards
What is anthropometrics?
Measurement of the human body
What percentage of Americans are obese?
about 1/3 (34.9%)
What measurements are involved in anthropometrics?
- Weight/Height/BMI
- Girth Measurements
- Skinfold Calipers
- Hydrostatic Weighing
- Bod Pod
- Limb Length
- Finger Pressure (peripheral edema)
Which measurement is considered the gold standard?
Hydrostatic weighing
BMI classifies a persons _____/_______ ratio.
height/weight
What are the 4 categories of BMI and what are their values?
- Underweight = <18.5%
- Normal = 18.5-24.9%
- Overweight = 25.0-29.9%
- Obese = >30%
How many subcategories of obesity are there?
3
Waist to hip ratio measurements involves taking the waist measurement where and the hip measurement where?
- Waist- narrowest part of the torso
- Hip- maximal circumference of hip/proximal thigh
What are the health risk values associated with the waist/hip ratio in regards to both females and males?
Low Risk
- M = .95 or below
- F = .80 or below
Mod Risk
- M = .96-1.0
- F = .81-.85
High Risk
- M = 1.0+
- F = 0.85+
What is the standard measurement for limb circumference?

What are the three variables associated with skinfold measurements?
Sex, age, and race
What are the two equations we can use for body density?
- 7 site formula
- 3 site formula
- Is hydrostatic weighing the gold standard?
- What is taken into account when performing hydrostatic weighing?
- Yes
- Body weight, water density, residual lung volume, air in GI
How does the bod pod work?
Measures air displacement
- How does a bioelectrical impedance work?
- What is important to consider?
- Measures conduction of electrical currents through the body
- hydration, temperature
