This MCQ was made to help you understand what your body is made of, what effects it and how to calculate and estimate BMI. This MCQ also relates to the learning outcomes mapped to the body compostion lecture in phase 1 at Warwick medical School. Good luck!

Describe body composition
The relative proportions of protein, fat, water, and mineral components in the body that make up total body weight
The relative proportions of protein, fat, water (excluding skin and bone) in the body that make up total body weight
The relative proportions of protein, fat (excluding skin and bone and water) in the body that make up total body weight
The relative proportions of water, and mineral components in the body that make up total body weight
What is fat free mass and what does it consist of?
Body mass that only takes fat mass into consideration
Body mass that consists of free fatty acids
Body mass that does not take fat mass into consideration (contains water, protein, bone minerals)
Body mass only considering the fat surrounding the abdominal region
What is body weight composed of?
Free fat mass + water and bone minerals
Free fat mass + Fat mass
Fat mass + muscle mass + bone mass + water
Bone mass + fat mass + free fat mass
How do you measure BMI?
BMI = mass (kg)/(height (m))^2
BMI = (mass (kg)) ^ 2 / height (m)
BMI = (mass (kg)) ^ 2 / height (cm)
BMI = mass (kg)/2(height (cm))
Your white British female patient weighs 53 kg and is 168 cm tall. Calculate and interpret their BMI
You would like to measure the BMI of a bed bound patient, but they cannot stand up to have their height taken for the calculation. What measure could you use to approximate their BMI?
Mid upper arm circumference
Knee height calliper
Which of the following is not a limitation of BMI?
It does not take age and gender into consideration
It does not take body composition into account
It does not take bone density into account
BMI in children and adolescence can vary due to differences in fat-free mass
Which of the following is a limitation in approximating BMI in measures such as mid arm circumference?
The arm stores less fat relative to the rest of the body
It does not take body composition into account (ex.body building, muscle wasting)
This measure is not evidence based and has fallen out of practice
More accurate measures such as ulnar length are better estimators of BMI
Which of the following is not a way of measuring body composition?
Knee height calliper
What is a gynoid vs an android body type?
Gynoid relates to lower body obesity, and adenoid to central obesity
gynoid relates to central obesity and android to lower body obesity
Gynoid relates to female body composition, adenoid to male body composition
Gynoid relates to free fat mass and adenoid to higher body mass
What diseases can be linked to overnutrition?
What is the M.U.S.T tool?
A 5 step screening tool used to identify adults at risk for metabolic syndrome
A 5 step screening tool used to identify adults at risk for undernuitrition, malnourished or obese
A 5 step screening tool used to identify adults at risk of diabetes
A 5 step screening tool used to identify adults at risk of cardiovascular disease
Which of the following is not a biological factor that affects body composition?
Which of the following is not a lifestyle factor that affects body composition?
Drugs and alcohol
Which of the following is not a biometric factor that affects body composition?
Free muscle mass
