AND INSIGHTS
●● what is the relationship between mortality risk and BMI
Answer: low BMI increase risk
moderate Bmi= low risk
high BMI = high risk
●● Risk classification according to BMI (memorize)
Answer: underweight <18.5
Normal 18.5-24.9
overweight (25-25.9)
obesity >30
class 1 30-34.9
,class 2 35-39.9
class3 > 40
●● Assessment of Body Composition
Answer: generally divided in fat and fat-free mass
●● fat free mass
Answer: everything that is not fat (bone, organs, muscles, connective
tissues etc.)
●● what is the best method to find body composition
Answer: dissection (because its accurate)
●● Densitometry
Answer: process that determines the density of a body mass( Body
volume is determined from measurement of body mass in air and while
immersed in water using Archimedes' principle.)
●● Visible Human Project
Answer: a computerized library of human anatomy at the National
Library of Medicine, seeking to create accurate, three-dimensional
representations of the male and female body.
,●● magnetic resonance imaging (MRI)
Answer: a technique that uses magnetic fields and radio waves to
produce computer-generated images that distinguish among different
types of soft tissue; allows us to see structures within the different parts
of the body
(expensive option ) requires
takes multiple imges requires alot of time to scan 30mins
●● computed tomography (CT)
Answer: a series of x-ray images are taken in multiple views (especially
cross section)
uses radiation
(can be used to construct 3d images)
●● dual energy x-ray absorptiometry (DEXA)
Answer: A highly accurate method of measuring body composition and
bone mass and density using multiple low-energy X rays.
also uses radiation
, ●● How does DEXA work?
Answer: measures bone density based on how easily the x-rays go
through the bone; if they are more dense, the x-ray is harder to get
through; if they are less dense, the x-ray goes through easier
●● Bioelectrical Impedance Analysis (BIA)
Answer: A method of assessing body composition by running a low-
level electrical current through the body.
●● what factors affects BIA
Answer: Affected by hydration status
Model of device used
Can provide regional body faT
●● Ultrasound
Answer: uses differences in how sound waves travel through tissue to
make images
●● Anthropometry
Answer: Measurement of the human body
●● skin fold measures
