Body Composition Analysis

AAWC offers the most advanced body composition analysis – SECA mBCA, which calculates a whole range of vital body composition parameters with medical precision, in just 17 seconds! No pain, no injections, no undressing. Just stand on the scale & it does the work! Some of these essential body numbers everyone needs to know about their bodies include:

Fat Mass/Fat-Free Mass FM/FFM

· The medically precise distinction between fat mass and fat-free mass is important when weight changes occur – whether you are overweight, obese or malnourished

· Amount of fat mass is important for weight management, diabetes or general health

· A metabolic unhealthy person with insulin resistance, for example, nearly exclusively loses water when starting weight loss treatments, which is why assessing fat mass is essential to prevent misinterpretations

· Interpreting fat mass is also crucial in malnourished patients, especially elderly or chronically sick patients with cancer, heart, lung, kidney, liver or psych diseases

· Assessing or monitoring fat mass with athletes in sports medicine can determine the fitness level or controlling trainings

Skeletal Muscle Mass SMM

· The development and retention of skeletal muscle mass plays an important role in malnourished patients, in the area of sports medicine, and in the reduction of body weight. The display shows the individual values for each of the patients, extremities as well as their torso

· Quantifying muscle mass is essential when monitoring weight changes in overweight & obese

· It is essential that the majority of existing muscle mass is preserved when reducing weight in weight management settings, in diet programs in diabetology, cardiology and hospital nutrition in general

· Especially malnourished patients with sarcopenic and cachectic states – often found in oncology, cardiology, nephrology require an adequate amount of muscle mass to reduce morbidity and mortality. Sarcopenia and cachexia are also found in psychology when it comes to anorexia nervosa or bulimia

· Another interesting area of application for assessing or monitoring muscle mass is in the sports medicine field when it comes to determining the fitness level and controlling trainings, physiotherapies and rehabilitation

Visceral Fat VAT

· The higher the visceral fat value, the higher the risk of cardiometabolic illnesses. With the seca mBCA, negative trends can be detected early in order to initiate corresponding treatments and therapies

· The easy and quick assessment of visceral fat is an essential brick for estimating the cardiometabolic risk

· It has therefore become an established value especially overweight and obese patients

· The medical fields wanting to obtain visceral fat values are bariatrics, weight management, diabetology, hospital nutrition, cardiology and general health

Body Composition Chart BCC

· The BCC displays fat mass and fat-free mass in a graphic which enables you to interpret body composition at a glance

· In addition, a series of measurements can be used to determine whether the fat mass or fat-free mass contributed to any weight change

· It is therefore an essential tool in weight management, diabetology, cardiology, general health or hospital nutrition when it comes to losing weight

· In malnourished individuals, for example in oncology, cardiology, nephrology but also in psychology – when it comes to anorexia nervosa or bulimia – the Body Composition Chart delivers accurate and important information on body composition changes

· It helps to determine the fitness level and to control physiotherapies and rehabilitation procedures in sports medicine

How do I interpret the BCC?

The Body Composition Chart has two axes. The Fat Mass (FM) is on the Y-axis and Fat-Free Mass (FFM) is on the X-axis. Each value is presented as an index, which means – as in the BMI – that the values are normalized by height. This allows a comparison to be made between a man who is 5 ft and a man that is 6.5 ft. Add the FMI and FFMI values together to yield the BMI. The Body Composition Chart is a two-dimensional (or over time a three-dimensional) BMI that shows what contributes to weight loss – fat mass or muscle mass. The center of the graphic is the statistical average for the specific patient. In this case, the fat mass is slightly below average for a man because the measurement point moves downwards from the midpoint. The Fat-Free Mass is above-average since the measurement point moves to the right of the midpoint.

Physically active obese people have both an increased FM and an increased FFM. This type of body composition is reflected in the points in the two upper right quadrants. A low FM with a simultaneous high FFM indicates an athletic body composition and a low FM with low FFM indicates a lean composition. An undesirable body composition is one with an elevated Fat Mass – obesity – along with a reduced Fat-Free Mass – muscle deterioration, referred to as sarcopenic obesity.

Total Body Water/Extracellular Water TBW/ECW

· The medically precise assessment of total body water and extracellular water is essential in nephrology to better evaluate the dry weight

· The distribution of fluids detects edema which are often found in cardiology or other fields of internal medicine like pneumology or hepatorenal in nephrology patients, which mostly also require hospital nutrition aid

· In sports medicine the management of fluids is valuable for fluid management to prevent dehydration and maximize individual performance

· The determination of body water also helps to better understand weight loss situations in weight management, diabetes, cardiology or general healthwhere great amounts of water are lost when commencing diets due to for example insulin resistances

Bioelectrical Impedance Vector Analysis BIVA

· Bioelectrical Impedance Vector Analysis (BIVA) delivers information on the amount of body fluids water and phase angle (marker for cell metabolism) at the same time

· It therefore assists to evaluate the hydration status, which is valuable in sports medicine, but also may identify patients with fluid overloads, which are typically found in nephrology or cardiology

· On the other hand it delivers information on the nutritional status and has proven to be valuable in weight management, diabetology, oncology, but also in psychology when it comes to anorexia nervosa or bulimia

· In general health the BIVA readings allows to categorize patients and allows to draw hypothesizes, which can be verified with specific additional tests

How do I interpret the BIVA?

Bioelectrical Impedance Vector Analysis (BIVA) presents information on Total Body Water and the phase angle in a single diagram. This allows the doctor to assess the patient’s hydration status, nutritional status and fitness level. By considering these values together, the doctor can distinguish, for example, an overhydrated patient with heart failure from a bodybuilder. While the amount of body water is identically high (a bodybuilder’s body water is elevated because muscle contains 75% of intracellular water), the bodybuilder has a high phase angle and the patient with heart failure has a low phase angle, given the overhydration in the extracellular area.

Phase Angle PA

· Phase angle correlates with the nutritional and functional (metabolic) status of individuals

· A sound nutritional state as well as a healthy metabolism result in a high phase angle value

· It has proven to show disease severity, especially in malnutrition like cancer patients, HIV, etc

· Low phase angle results in apparently healthy, young individuals should be followed up by differentiated diagnosis (blood tests, etc.)

· This is important for general health during routine checkups, but also in sports medicine for the detection of exhaustive states

· As low phase angle values also correlate with malnutrition it is an important marker in psychology when it comes to anorexia nervosa or bulimia or in hospital nutrition in general

How can I interpret the phase angle?

The phase angle is an indicator of overall health, metabolic activity and nutritional status. Percentiles in the normal ranges for age and gender are suitable for interpretation of the data. In addition to an adequate cell mass (BMI in the normal range), a pronounced muscle mass has a strong influence on the phase angle. Since men have a higher proportion of muscle than women typically men have a higher phase angle. As we age, the phase angle declines with muscle mass and metabolic changes. Low phase angle values result from reduced cell mass (underweight), chronic illness and in particular from overhydration (e.g., in dialysis).
