Questions such as whether body weight or lean body mass is the best indicator of when premature babies are healthy enough to go home, or whether very chubby babies are more prone to develop cardiovascular problems as adults, can only be answered with research using precise body composition measurements and appropriate standard reference values.
The CNRC Body Composition Laboratory is the only laboratory of its type in the nation that can provide a complete complement of body composition measurements in all populations ranging from low-birth-weight infants to adults.
Data from the body composition laboratory research is also being used to develop age, gender and ethnic-specific body composition standard references, such those for bone mineral content and bone mineral density.

 Physiology & Psychology: Performance Benchmarks -- Body Composition
Body composition refers to the relative percentage of muscle, fat, bone, and other tissue of which the body is composed.
Because the amount of body fat, not the amount of weight, is the important factor in living a healthy life, it is better to determine the percentage of your body weight that is body fat (percent body fat).
Use the skinfold sum and your age to determine your percent fat in the body composition chart.

 Body Composition: Healthy Under The Skin
At this level of body fat percentage, the incidence of injuries and maladies to knees, backs, and ankles, the major support structures, is almost three times that of people with just average body fat percentages.
Being "average" in body composition is not necessarily healthy, as the overall population is more over-fat than 25 years ago, so a desirable situation is to have slightly less than an "average" body fat percentage.
Body composition or body fat scores normally trend upward with age, yet that is the result of our adult population being less physically active than in the past, and in actuality, many health experts feel the age-related rise is unhealthy.
