Name and explain in short, the most commonly used method of indirectly estimating percent body fat in clinical settings? Write three advantages.

Expert Solution

Body fat refers to the amount of fat deposited in the adipose tissues. Body fat percentage refers to the percentage of essential body fat and storage body fat that is necessary to maintain normal human life.

In clinical setting the fat percentage is calculated using Dual energy X ray absorptiometry (DEXA). It also refers to bone densitometry. X ray is used to scan the entire body to determine body fat percentage and the bone mineral density.

DEXA scan helps to measure the density of bones at the bony prominences at the spine,hip,arm,forearm. Two types of DEXA scan are done namely : Central DEXA - that helps to measure density in the hip and spine. Peripheral DXA helps to evaluate the density of bone in finger,hand,foot. The results are interpreted using T Score to compare the bone density between the younger age group people with same gender with peak bone mass. Z score is to analyse the density of fat in relation to the other people of same age group.

Advantages:

- Dexa scan is more useful for the athletes to evaluate the fat percentage and bone density.

- The use of low radiation dose helps the less exposure of the individual

- It is easy to do regional analysis of whole body to determine the fat percentage estimation.

Body mass index (BMI) is a reliable indicator of body fat for most children and teens. BMI is calculated from a child’s weight and height and is used as an easy-to-perform method of screening for weight categories that may lead to health problems. For children and teens, BMI is age- and sex-specific and is often referred to as BMI-for-age. The Centers for Disease Control and Prevention (CDC) reports BMI-for-age growth charts for girls as well as boys to obtain a...

Three percent of a man's body is essential fat; for a woman the percentage is closer to 12.5%. As the name implies, essential fat is necessary for a normal healthy body. Fat is stored in small amounts throughout the body. Too much fat, however, can be dangerous to your health. For men between 18 and 39 years old, a healthy percent of body fat ranges from 8% to 19%; for women of the same age, it's 21% to 32%. Measuring...
