Clin 1 midterm 1 Flashcards
What are stages of nutrient deficiency progression and how canwe assess each stage
What is the difference betweeen anthropometry and body composition
how can you assess body size and composition
Heght,weight,circumferences, skinfolds, ratios
Anthropometry is used to estimate ___ and design ___
Nutritional status
Intervention
Because body composition correlated with function
Can mesurements performed one time be called reliable?
No, need to perform at least 3 times
Can you determine specific nutrient deficiences with anthropometric measurements?
No
How can you assess the amount of fat in the body
With skinfold thickeness and waist circumeference
What is the proportion of fat, skeleton/skin, extracellular, plasma proteins, viscera, skeletal muscles in the body
How can you identify viscera part
Albumin, TTR (protein made by the liver that helps carry thyroid hormone and vitamin A in the blood), RBP -> proteins secreted by the liver
How many cl is stored in muscle and in fat
Fat- 190 000 kcal
Skeletal muscle- 26k kcal
How can you measure the maount of skeletal muscle
arm muscle circumference (MAMC)
Creatinine height index (CHI)
As a simple model how usually body is broken down
2 compartment (fat and fat-free mass)
3 compartment ( 2 compaartment + bones)
How much weigh the total protein part of the body
12 kg
How height should be measured if standing
Using stadiometer ,barefoot, heels and shoulders touching the wall, Frankfurt plane parallel to the floor)
How height should be measured if the person cannot stand
Knee height (90 degrees in the knee and measure form the knee to the bottom of the heel). From that using the equation to estimate thhe height
All the measurements should be performed____
In the same conditions (time, fasted state, etc.) to compare over time and avoid any variations
Is arm span a recommended method to measure height?
No, used if the person is not able to stand straight and not for Asians,African Americans, spinal deformations
Only a rough estimation
Knee height is measured using
Calipers
How can measure frame size
By wrist circumference
r=height (cm)/wrist circumference (cm)
Not used on its own , is used to confirm with other methods
Classification of frame size in men aand women
What is weight
Sum of all components at each level of body composition -measure of body stores
How weight can be measured and what considerations should be taken into account
Using standing, chair, or bed scales
• Wearing minimal clothing, no shoes
• Timing and hydration changes
• No single measure of weight accounts for body composition
Amputation adjustments and calculate what will happen with weight calcualtion if arm was amputated and the patient wasa weighted at 70 kg
