TANITA Sarcopenia Detection

Sarcopenia detection

Whether your patient’s experience of Sarcopenia is due to aging, chronic illness, acute conditions, or lifestyle factors, the health costs of late diagnosis are clear.

• With Tanita bio-impedance analysis, you will benefit from the highest levels of precision and accuracy, with technology validated against the gold standard in body composition.
• Specialist measurements support your accurate diagnostic, clinical and prescribing decisions so that each patient can receive tailored support.

Early detection and treatment is key

There is a growing body of evidence indicating poor nutritional status (as measured by a range of markers including fat-free mass & muscle mass) is linked with poorer patient outcomes and worse prognosis.(1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12), (13)
Sarcopenia is an independent risk factor for mortality in all patients and as such, was reclassified as a disease in 2016.(14)
Cachexia is the immediate cause of death for 1 in 5 cancer patients.(15)
Patients particularly at risk from surgical complications, increased hospital stays, poorer recovery and mortality include cancer patients, patients with COPD and CF and patients suffering from renal disease.

The cost of Sarcopenia

It is estimated that Sarcopenia results in treatment related annual excess costs of £2.5 billion in the UK.(16)

Sarcopenia is also associated with increased risk of:

Who is the sarcopenia patient?

• Weight and BMI alone do not allow for accurate estimation of lean mass vs fat mass.
• It is impossible to diagnose without a holistic assessment of body composition.
• Body composition analysis enables you to quickly and easily diagnose low muscle mass and sarcopenia.
• Tanita technology uses bio-impedance analysis to provide an accurate assessment of body composition.
  

Increasing the risk of Sarcopenia

Sarcopenia is a progressive loss of muscle mass and function as a consequence of aging. However, it is increasingly being observed in younger people.(17)

The risk of developing or progressing Sarcopenia is increased by:

• Sedentary lifestyle
• Smoking
• Poor diet and malnutrition
• Genetic factors
• Some neurological conditions (stroke, Parkinson’s disease, multiple sclerosis, myasthenia gravis, etc.).
• Inflammatory disease
• Physical disability
• Cachexia
  

Body composition and bio-impedance analysis

How does it work?
Electrodes send a very low voltage, safe electrical current through your feet, legs and abdomen.
In segmental models you will also hold 4 electrodes and the signal is passed from arm to arm and a cross sectional hand to foot.
Tanita multi frequency technology is able to penetrate the cell membrane, offering a much more accurate interpretation of body composition.

What does it measure?

Resistance (R)

Resistance is the effect on an alternating current caused by ‘resistivity’ or the energy dissipating characteristics of the body. A low resistance is consistent with a high amount of fat-free mass. A high resistance is consistent with a lower amount of fat-free mass. Old single frequency technology could only measure resistance.  Resistance is related to water in the body. Low resistance, indicating high conductivity, is due to large amounts of water in the body. As fat-free mass within the body is approximately  75% water, resistance in the body is proportional to the amount of fat-free mass. Resistance is measured in units called ohms.

Reactance (X)

Reactance is the effect on an alternating current caused by the capacitance, or energy storage of the body. By measuring reactance, it is possible to determine the body’s capacitance and the size and integrity of body cell mass. A high capacitance or high reactance indicates large quantities of intact cellular membranes.

• Independent studies worldwide highlight Tanita as the BIA Gold Standard within the scientific community.
• The Tanita Advisory Board (TMAB) ensures Tanita remains at the forefront of scientific advances.
• Tanita invest in ground breaking research projects including the world’s first child centiles for body fat and muscle mass, the health of older people and sarcopenia obesity.
• Award winning Japanese manufacturing which guarantees the highest quality and meets strict international quality standards.
• Tanita utilizes 4C methodology in refining our algorithms and regression equations to ensure the most accurate bio-impedance and body composition analysis available.

Welcome to the next level in 4ccuracy

Introducing the 4-Compartment measurement from Tanita
Tanita continues to offer the most accurate calculation of fat, lean mass (or muscle) and bone mineral density available, but with 4C monitoring we go even further, giving an unparalleled, 4-Compartment measurement.
Our new 4C method will enable you to fully assess levels of body fat, protein, bone mineral mass and water within the body.

What is the 4-Compartment (4C) model?
The 4C model divides body weight into fat, water, mineral, and protein using the gold standard method for measuring each element.
The 4C model involves the measurement of body mass or weight, total body volume (air displacement), total body water (D20), and bone mineral (DXA); however, specialized laboratory equipment is required minimizing the availability of the 4C method to many clinicians and researchers.

“The 4-Compartment model is a gold standard method to assess body composition in many conditions such as over and under nutrition, hydration, obesity and sarcopenia.”
