which person is at a greater risk for health issues related to being overweight or
obese?
Janet has a BMI of 28 and a waist to hip ratio of 0.95. Fred has a BMI of 28.9 and a
waist to hip ratio of 0.78. - correct answer-Janet. Both have a BMI that indicates
being overweight, but Janet has a more at-risk waist to hip ratio as her value is
greater than 0.8.
(Women should have a waist to hip ration less than 0.8 and males should have
less than 0.9.)
What range of BMI values represents a person with a healthy weight? - correct
answer-18.5-<25
What shape has the greatest health risks and why? - correct answer-Apple,
because the fat in the abdominal tissues interferes with the liver's ability to use
insulin.
, What are some factors that can influence an individual's BMR? (list at least 5) -
correct answer-The BMR varies per person based on a number of factors such as;
gender, lean body mass, body size, temperature, age, nervous system activity,
caffeine, smoking, pregnancy, and diet.
The following can be used to determine a person's body fat: - correct answer-
calipers, underwater weighing, electrical resistance, direct calorimetry
Anthropometrics estimates a person's percentage of fat by: - correct answer-
using a caliper
What range of BMI values represents a person that is obese? - correct answer->
30
Indirect calorimetry estimates a person's energy requirements by: - correct
answer-comparing the amount of oxygen consumed with the amount of carbon
dioxide expired
Ignoring factors other than age, how does BMR change as a person grows older?
What does this mean for their dietary intake? - correct answer-As we age our
BMR declines by 1-2% per decade. If no change in diet or activity level occurs
from one decade to the next, a slow weight gain will be the result.
Calculate the Estimated Energy Requirement (EER) for a female who is 23 years
old, 5 feet 4 inches tall, and 130 pounds with a sedentary lifestyle. Use BMR and
an activity factor to find the EER. - correct answer-BMR Calculations:
Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age)
