Final answer:
A determination of percent body fat is required on personnel when assessing overall health and disease risks. Body fat content can be measured using methods such as skin-fold tests, hydrostatic weighing, and DEXA. These measurements help assess weight, fat mass, and relative risk of chronic diseases.
Step-by-step explanation:
A determination of percent body fat is required to be made on personnel when assessing overall health and disease risks. Body fat content can be measured using various methods such as skin-fold tests, hydrostatic weighing, and dual-energy X-ray absorptiometry (DEXA).
The skin-fold test involves using a caliper to measure the thickness of skin on different parts of the body. Hydrostatic weighing requires the person to be completely submerged in water to calculate their body density. DEXA uses low-dose X-ray beams to measure bone density and estimate fat content.
By determining percent body fat, health professionals can assess an individual's weight, fat mass, and distribution, and their relative risk of chronic diseases. This information can help in diagnosing obesity and developing appropriate health interventions.
