Body composition evaluation -

Measurement of the mid-arm muscle circumference is an easy tool to diagnose sarcopenia [ 38 ]. The mid-arm muscle circumference has been shown to be correlated with survival in patients with cirrhosis [ 39,40 ], HIV infection [ 41 ], and COPD in a stronger way than BMI [ 42 ].

The relation between FFM loss and mortality has been extensively shown with BIA [ 21,22,23,24,25,26,27,28,31,37 ], which is the most used method. Recently, very interesting data suggest that CT could evaluate the disease prognosis in relation to muscle wasting. In obese cancer patients, sarcopenia as assessed by CT measurement of the total skeletal muscle cross-sectional area is an independent predictor of the survival of patients with bronchopulmonary [ 5,7 ], gastrointestinal [ 5 ], and pancreatic cancers [ 6 ].

FFM assessed by measurement of the mid-thigh muscle cross-sectional area by CT is also predictive of mortality in COPD patients with severe chronic respiratory insufficiency [ 43 ]. In addition to mortality, a low FFMI at hospital admission is significantly associated with an increased LOS [ 3,44 ].

A bicentric controlled population study performed in 1, hospitalized patients indicates that both loss of FFM and excess of FM negatively affect the LOS [ 44 ]. Patients with sarcopenic obesity are most at risk of increased LOS.

This study also found that excess FM reduces the sensitivity of BMI to detect nutritional depletion [ 44 ]. Together with the observation that the BMI of hospitalized patients has increased during the last decade [ 17 ], these findings suggest that FFM and FFMI measurement should be used to evaluate nutritional status in hospitalized patients.

BIA measures the phase angle [ 45 ]. The phase angle threshold associated with reduced survival is variable: less than 2. The phase angle is also associated with the severity of lymphopenia in AIDS [ 56 ], and with the risk of postoperative complications among gastrointestinal surgical patients [ 57 ].

The relation of phase angle with prognosis and disease severity reinforces the interest in using BIA for the clinical management of patients with chronic diseases at high risk of undernutrition and FFM loss.

In summary, FFM loss or a low phase angle is related to mortality in patients with chronic diseases, cancer including obesity cancer patients , and elderly patients in long-stay facilities.

A low FFM and an increased FM are associated with an increased LOS in adult hospitalized patients. The relation between FFM loss and clinical outcome is clearly shown in patients with sarcopenic obesity. In these patients, as the sensitivity of BMI for detecting FFM loss is strongly reduced, body composition evaluation appears to be the method of choice to detect undernutrition in routine practice.

Overall, the association between body composition, phase angle, and clinical outcome reinforces the pertinence of using a body composition evaluation in clinical practice.

Numerous methods of body composition evaluation have been developed: anthropometry, including the 4-skinfold method [ 58 ], hydrodensitometry [ 58 ], in vivo neutron activation analysis [ 59 ], anthropogammametry from total body potassium [ 60 ], nuclear magnetic resonance [ 61 ], dual-energy X-ray absorptiometry DEXA [ 62,63 ], BIA [ 45,64,65,66 ], and more recently CT [ 7,43,67 ].

DEXA, BIA, and CT appear to be the most convenient methods for clinical practice fig. Compared with other techniques of body composition evaluation, the lack of reproducibility and sensitivity of the 4-skinfold method limits its use for the accurate measurement of body composition in clinical practice [ 33,34 ].

However, in patients with cirrhosis [ 39,40 ], COPD [ 34 ], and HIV infection [ 41 ], measurement of the mid-arm muscle circumference could be used to assess sarcopenia and disease-related prognosis.

DEXA allows noninvasive direct measurement of the three major components of body composition. The measurement of bone mineral tissue by DEXA is used in clinical practice for the diagnosis and follow-up of osteoporosis.

As the clinical conditions complicated by osteoporosis are often associated with undernutrition, i. elderly women, patients with organ insufficiencies, COPD [ 68 ], inflammatory bowel diseases, and celiac disease, DEXA could be of the utmost interest for the follow-up of both osteoporosis and nutritional status.

However, the combined evaluation of bone mineral density and nutritional status is difficult to implement in clinical practice because the reduced accessibility of DEXA makes it impossible to be performed in all nutritionally at-risk or malnourished patients.

The principles and clinical utilization of BIA have been largely described in two ESPEN position papers [ 45,66 ]. BIA is based on the capacity of hydrated tissues to conduct electrical energy. The measurement of total body impedance allows estimation of total body water by assuming that total body water is constant.

From total body water, validated equations allow the calculation of FFM and FM [ 69 ], which are interpreted according to reference values [ 70 ]. BIA is the only technique which allows calculation of the phase angle, which is correlated with the prognosis of various diseases.

BIA equations are valid for: COPD [ 65 ]; AIDS wasting [ 71 ]; heart, lung, and liver transplantation [ 72 ]; anorexia nervosa [ 73 ] patients, and elderly subjects [ 74 ]. However, no BIA-specific equations have been validated in patients with extreme BMI less than 17 and higher than Nevertheless, because of its simplicity, low cost, quickness of use at bedside, and high interoperator reproducibility, BIA appears to be the technique of choice for the systematic and repeated evaluation of FFM in clinical practice, particularly at hospital admission and in chronic diseases.

Finally, through written and objective reports, the wider use of BIA should allow improvement of the traceability of nutritional evaluation and an increase in the recognition of nutritional care by the health authorities. Recently, several data have suggested that CT images targeted on the 3rd lumbar vertebra L3 could strongly predict whole-body fat and FFM in cancer patients, as compared with DEXA [ 7,67 ].

Interestingly, the evaluation of body composition by CT presents great practical significance due to its routine use in patient diagnosis, staging, and follow-up. The muscles included in the calculation of the muscle cross-sectional area are psoas, paraspinal muscles erector spinae, quadratus lumborum , and abdominal wall muscles transversus abdominis, external and internal obliques, rectus abdominis [ 6 ].

CT also provided detail on specific muscles, adipose tissues, and organs not provided by DEXA or BIA. L3-targeted CT images could be theoretically performed solely, since they result in X-ray exposition similar to that of a chest radiography.

In summary, DEXA, BIA, and L3-targeted CT images could all measure body composition accurately. The technique selection will depend on the clinical context, hardware, and knowledge availability.

Body composition evaluation by DEXA should be performed in patients having a routine assessment of bone mineral density.

Also, analysis of L3-targeted CT is the method of choice for body composition evaluation in cancer patients. Body composition evaluation should also be done for every abdominal CT performed in patients who are nutritionally at risk or undernourished. Because of its simplicity of use, BIA could be widely implemented as a method of body composition evaluation and follow-up in a great number of hospitalized and ambulatory patients.

Future research will aim to determine whether a routine evaluation of body composition would allow early detection of the increased FFM catabolism related to critical illness [ 75 ]. The evaluation of FFM could be used for the calculation of energy needs, thus allowing the optimization of nutritional intakes according to nutritional needs.

This could be of great interest in specific situations, such as severe neurologic disability, overweight, and obesity. In 61 children with severe neurologic impairment and intellectual disability, an equation integrating body composition had good agreement with the doubly labeled water method.

It gave a better estimation of energy expenditure than did the Schofield predictive equation [ 36 ]. However, in 9 anorexia nervosa patients with a mean BMI of In overweight or obese patients, the muscle catabolism in response to inflammation was the same as that observed in patients with normal BMI.

Indeed, despite a higher BMI, the FFM of overweight or obese individuals is similar or slightly increased to that of patients with normal BMI. Thus, the use of actual weight for the assessment of the energy needs of obese patients would result in overfeeding and its related complications.

Thus, follow-up of FFM by BIA could help optimize nutritional intakes when indirect calorimetry cannot be performed. Body composition evaluation allows a qualitative assessment of body weight variations.

Body composition evaluation could be used for the follow-up of healthy elderly subjects [ 90 ]. Body composition evaluation allows characterization of the increase in body mass in terms of FFM and FM [ 81,91 ].

After hematopoietic stem cell transplantation, the increase in BMI is the result of the increase in FM, but not of the increase in FFM [ 81 ]. By identifying the patients gaining weight but reporting no or insufficient FFM, body composition evaluation could contribute to influencing the medical decision of continuing nutritional support that would have been stopped in the absence of body composition evaluation.

In summary, body composition evaluation is of the utmost interest for the follow-up of nutritional support and its impact on body compartments. This point has been recently illustrated in oncology patients with sarcopenic obesity. FFM loss was determined by CT as described above.

In cancer patients, some therapies could affect body composition by inducing muscle wasting [ 92 ]. In turn, muscle wasting in patients with BMI less than 25 was significantly associated with sorafenib toxicity in patients with metastatic renal cancer [ 8 ].

In metastatic breast cancer patients receiving capecitabine treatment, and in patients with colorectal cancer receiving 5-fluoro-uracile, using the convention of dosing per unit of body surface area, FFM loss was the determinant of chemotherapy toxicity [ 9,10 ] and time to tumor progression [ 10 ].

In colorectal cancer patients administered 5-fluoro-uracil, low FFM is a significant predictor of toxicity only in female patients [ 9 ]. The variation in toxicity between women and men may be partially explained by the fact that FFM was lower in females.

Indeed, FFM represents the distribution volume of most cytotoxic chemotherapy drugs. In 2, cancer patients, the individual variations in FFM could change by up to three times the distribution volume of the chemotherapy drug per body area unit [ 5 ]. Thus, administering the same doses of chemotherapy drugs to a patient with a low FFM compared to a patient with a normal FFM would increase the risk of chemotherapy toxicity [ 5 ].

These data suggest that FFM loss could have a direct impact on the clinical outcome of cancer patients. These findings justify the systematic evaluation of body composition in all cancer patients in order to detect FFM loss, tailor chemotherapy doses according to FFM values, and then improve the efficacy-tolerance and cost-efficiency ratios of the therapeutic strategies [ 93 ].

corticosteroids, immunosuppressors infliximab, azathioprine or methotrexate , or sedatives propofol. In summary, measurement of FFM should be implemented in cancer patients treated with chemotherapy.

Clinical studies are needed to demonstrate the importance of measuring body composition in patients treated with other medical treatments. The implementation of body composition evaluation in routine care presents a challenge for the next decades.

Indeed the concomitant increases in elderly subjects and patients with chronic diseases and cancer, and in the prevalence of overweight and obesity in the population, will increase the number of patients nutritionally at risk or undernourished, particularly those with sarcopenic obesity.

Body composition evaluation should be used to improve the screening of undernutrition in hospitalized patients. The results could be expressed according to previously described percentiles of healthy subjects [ 95,96 ].

Body composition evaluation should be performed at the different stages of the disease, during the course of treatments and the rehabilitation phase. BIA, L3-targeted CT, and DEXA represent the techniques of choice to evaluate body composition in clinical practice fig. In the setting of cost-effective and pragmatic use, these three techniques should be alternatively chosen.

In cancer, undernourished, and nutritionally at-risk patients, an abdominal CT should be completed by the analysis of L3-targeted images for the evaluation of body composition. In other situations, BIA appears to be the simplest most reproducible and less expensive method, while DEXA, if feasible, remains the reference method for clinical practice.

By allowing earlier management of undernutrition, body composition evaluation can contribute to reducing malnutrition-induced morbidity and mortality, improving the quality of life and, as a consequence, increasing the medico-economic benefits fig.

The latter needs to be demonstrated. Moreover, based on a more scientific approach, i. allowing for printing reports, objective initial assessment and follow-up of nutritional status, and the adjustment of drug doses, body composition evaluation would contribute to a better recognition of the activities related to nutritional evaluation and care by the medical community, health care facilities, and health authorities fig.

Screening of undernutrition is insufficient to allow for optimal nutrition care. This is in part due to the lack of sensitivity of BMI and weight loss for detecting FFM loss in patients with chronic diseases.

Methods of body composition evaluation allow a quantitative measurement of FFM changes during the course of disease and could be used to detect FFM loss in the setting of an objective, systematic, and early undernutrition screening. FFM loss is closely related to impaired clinical outcomes, survival, and quality of life, as well as increased therapy toxicity in cancer patients.

Thus, body composition evaluation should be integrated into clinical practice for the initial assessment, sequential follow-up of nutritional status, and the tailoring of nutritional and disease-specific therapies. Body composition evaluation could contribute to strengthening the role and credibility of nutrition in the global medical management, reducing the negative impact of malnutrition on the clinical outcome and quality of life, thereby increasing the overall medico-economic benefits.

To minimise the technical error of measurement, measurement sites and techniques have previously been defined 9. Practitioners can become accredited in anthropometric measurement through the International Society for the Advancement of Kinanthropometry ISAK.

Skinfold measurements taken just one centimetre away from the defined ISAK sites have previously been shown to produce significant differences in measurement values at each site, indicating how important it is to mark and measure skinfolds correctly for accurate data Therefore, the intra-rater reliability of the test is extremely important.

Whole Body Plethysmography BodPod Air-displacement plethysmography ADP can allow for the calculation of body composition through a 2-compartment model, based on assumptions of value constants for FM and FFM densities. Body weight and body volume are determined by this method, with mass divided by volume providing a measure of density.

Again, this measurement is a non-invasive and quick method, with the advantage of not requiring exposure to radiation. BodPod has been shown to be a valid measure of group average body composition when compared to DEXA in female collegiate athletes However, research has suggested a difference of 5.

BodPod has also shown limited accuracy when attempting to determine changes over time 13 , a primary consideration when choosing an assessment method for athletes.

Body density is determined and then used to estimate body fat percentage. Again, this estimate is based on assumptions regarding the density of FFM, which may vary with age, gender, ethnicity and training status, potentially limiting its use in athletic populations Although this method was previously considered the gold standard by the American College of Sports Medicine, it is not without measurement error.

The results are highly reliant on subject performance, and as the process itself is uncomfortable, it may take multiple tests to get a valid measurement.

For example, measurement error can occur through unsuccessful attempts to blow all of the air out of the lungs, or air bubbles trapped in hair or swimsuits. Bioelectrical Impedance Analysis BIA BIA is based on the concept that electric current flows through the body at different rates depending on its composition It involves running a light electrical current through the body and determining body composition through the resistance of the tissues to the electrical current.

The low cost, speed of measurement and lack of need for technical expertise make BIA an attractive option for body composition measurement, particularly in epidemiological research.

However, the accuracy of BIA is dependent on several factors, and as a result, it is likely the least valid measure of body composition discussed in this article. BIA relies on empirical equations to estimate total body water, FFM and body cell mass; these equations use gender, age, weight, height and race as variables.

Therefore, for BIA to be used as a valid measure of body composition, the correct equation must be used based on these factors The validity of BIA in some populations has been questioned, particularly in obese patients 18 , and in those with conditions that may alter fluid distribution, such as oedema BIA data is influenced by hydration status, and although the standardisation of fluid intake in the hours before testing may reduce the effects of hydration on body composition measurements, there is a lack of standardisation, or at least its reporting, in current research This may also be true in applied practice with athletic populations.

Exercise has been shown to lead to vast inaccuracies in body composition analysis using BIA 21 , as has changes in hydration status As a result, BIA may not be suitable for determining body composition changes due to fluctuations in hydration status following training.

Body composition measurement in vivo is an estimate. As mentioned previously, the cost and practicality of measuring body composition vary greatly, and often there is a trade-off between the two. Each method has a use in certain settings, and it is the job of the practitioner or user to understand the benefits and drawbacks of each method.

A further issue with body composition is often the focus of individuals on their absolute body fat percentage values. Rather than focusing on an absolute body fat number, it may be of more value to standardise measurement and track changes over time.

As measures of body composition are developed, more accurate measurements of FM and FFM can be established in various athletic populations. This means that future research should aim to determine:. There are a multitude of body composition assessment tools available to the practitioner, each with varying cost, accessibility and accuracy in each population.

It is important to understand the benefits and limitations of each method, and how best to utilise each one in practice. Most assessment tools are useful in various settings, and accuracy can be improved with proper standardisation prior to testing. Learn how to improve your athletes' agility.

The terms fat-free Metabolic health forum and Type diabetes prevention strategies body mass are often incorrectly used interchangeably. Practical Uses of Body Composition Assessments for Personal Trainers Heyward and Stolarczyk suggest the following ways the personal trainer can use body composition measures: 1. To identify the client’s health risk associated with excessively low or high levels of total fat 2. To identify the client’s health risk associated with excessive accumulation of intra-abdominal fat 3. To promote the client’s understanding of health risks associated with too little or too much body fat 4.

Most diets compositio on body weight and efaluation loss over maintaining healthy body composition. Your body composition is the percentage of body fat, muscle, compositioj, and other tissues.

Read on to understand what body composition means and why physical fitness is preferable to weight loss. Body composition is the term used in the fitness svaluation health community to refer to the evaluatioj of fat, water, bone, muscle, skin, and other lean tissues that make up the body.

Typically, people break body composition into two groups: evapuation mass and fat-free mass. Fat mass Metabolic health forum the amount of body fat. Fat-free mass is all compositiin lean tissues Body composition evaluation your body like muscles, organs, bone, water, etc, Body composition evaluation.

Body Metabolic health forum index BMI is another evaluatino term used in the medical and Optimize fat burning community to describe body measurements.

Body fomposition is different from body Quench Your Thirst index because BMI focuses on how your compositjon body weight compares to your height. BMI is calculated by taking total body mass in kilograms kg and dividing it by height in meters m squared.

Body composition evaluation composition is important because it can give you a better idea of your health risk, especially if you fall in the overweight or obesity evaluztion for Metabolic health forum efaluation you have evaluatiln muscle and lean tissue.

Body composition is measured using tools to estimate your compposition fat percentage. The ways to measure Hormone balancing for premenstrual syndrome composition vary.

It uses a eevaluation measure to see how wide around specific Energy boosters for morning parts are. Circumference is often assessed on body compposition like the waist, arms, chest, thighs, and hips.

Research suggests carrying evaluarion weight on your abdomen is associated with an compositkon risk for health problems. The circumference method helps assess the risk for disease based on the weight you carry on your belly.

However, this method may not be the best if your goal is to assess your overall body fat percentage because it only measures the circumference and not the percentage of fat and muscle.

The dual energy X-ray absorptiometry scan, known as a DEXA scanuses low-energy X-rays to accurately measure the weight of bone, muscle, and body fat.

After the scan, you receive an assessment of your bone densitybody fat percentage, and mass of each body part. Many professionals consider the DEXA scan the gold standard for measuring muscle mass. However, it can be harder to find a place to have a DEXA scan done depending on where you live, and it may be a more expensive option.

Hydrostatic weighing measures the water displacement when someone is fully submerged in water. Hydrostatic weighing was long considered the gold standard for assessing body composition until other methods, like DEXA scans, were developed. While this method is accurate, some people find it difficult to stay submerged in water long enough for the assessment, and it may not be accessible.

A bioimpedance analysis BIA uses a painless, low-energy electrical current to assess fat mass, muscle mass, and hydration water mass. Muscle contains more water than fat, so it conducts the energy current better than fat.

Fat tissue impedes the movement of the current. The BIA scanner can assess body composition based on how the energy moves through the body. This test tends to cost less and may be easier to find than other types of scans. However, the accuracy of this assessment changes based on how hydrated you are.

If you drink too much water before the test, you could appear leaner than you are. Some other methods of assessing body composition include:. The best way to improve your body composition is to make healthy changes, like:.

Eating a diet full of highly processed foods that provide large amounts of sugar and fat is associated with gaining weight and body fat. Moving more and exercising regularly helps improve body composition. Research shows all types of exercise programs helped improve the body composition of people who were sedentary.

The results showed strength training programs that develop the whole body had the biggest impact on body composition and improving bone density.

Here are some tips to help you increase your physical activity. The amount of time you sleep and your sleep quality can greatly impact your body composition. A study found poor sleep quality was associated with:. Here are some tips to help increase your sleep quality:.

In addition to the above lifestyle changes, other changes that may help your body composition include:. Body composition is a measurement of the amount of body fat and lean tissue in your body. Body composition can be measured with tests like skinfold assessment, DEXA scan, body circumference, hydrostatic weighing, and bioimpedance analysis.

In addition, you may be able to improve your body composition by focusing on lifestyle changes like a healthy diet, exercise, sleeping better, and managing stress. Body composition can give you a better understanding of your current fitness and health level. In addition, repeating the body composition test over time can help you track your progress on your wellness journey.

Many calculations for finding healthy body weight use factors like age, sex, and height. These measures can be limited and provide an estimated range.

Still, finding your height on a BMI chart can give you an idea of what a healthy weight may be for you. Strength training and interval training may have a bigger impact on raising your muscle mass and lowering your body fat percentage. Centers for Disease Control and Prevention.

J Am Soc Nephrol ;— NEXT STEPS. In patients with non-small cell lung cancer, FFM loss determined by computerized tomography CT was observed in each BMI category [ 7 ], and in young adults with all types of cancer, an increase in FM together with a decrease in FFM were reported [ 29 ].
What does body composition mean?	While this method is accurate, some people find it difficult to stay submerged in water long enough for the assessment, and it may not be accessible. The BIA scanner can assess body composition based on how the energy moves through the body. Research Interests. Paiva SI, Borges LR, Halpern-Silveira D, Assunção MC, Barros AJ, Gonzalez MC: Standardized phase angle from bioelectrical impedance analysis as prognostic factor for survival in patients with cancer. About us Contact us Join our team Privacy policy Terms of use Terms and conditions Disclaimer. Final Thoughts Becoming a highly skilled SKF technicians takes careful practice and precise adherence to measurement procedures. There are multiple types of BIA tools available on the market.
What is Body Composition?	To obtain accurate measurements, you need to wear skin-tight clothing or a bathing suit during testing. The Bod Pod is the main ADP device currently used. It predicts your body fat with air rather than water. BIA devices detect how your body responds to small electrical currents. This is done by placing electrodes on your skin. Some electrodes send currents into your body, while others receive the signal after it has passed through your body tissues. Electrical currents move through muscle easier than fat due to the higher water content of muscle BIA devices work by sending small electrical currents through your body to see how easily they travel through your tissues. Many different devices are available, although advanced devices produce more accurate results. BIS and BIA devices look similar but use different technology. BIS uses a much larger number of electrical currents than BIA, in addition to high and low frequencies, to mathematically predict your amount of body fluid BIS also analyzes the information differently, and some researchers believe that BIS is more accurate than BIA 14 , However, similar to BIA, BIS uses the body fluid information it gathers to predict your body composition based on equations The accuracy of both of these methods depends on how similar you are to the people for whom these equations were developed However, BIS uses more electrical currents and processes the information differently. However, while BIA and BIS send currents through your whole body, EIM sends currents through smaller regions of your body These devices are placed on different parts of the body to estimate the body fat of those specific areas Because this device is placed directly on specific body regions, it has some similarities to skinfold calipers, although the technologies are very different. EIM injects electrical currents into small body regions. Portable devices are placed directly on different body parts to estimate the body fat percentage at those locations. More research is needed to establish the accuracy of this method. For some devices, you stand on a rotating platform for several minutes while the sensors detect your body shape. Other devices use sensors that rotate around your body. In this way, 3-D body scanners are similar to circumference measurements. However, a greater amount of information is provided by a 3-D scanner The method uses information about your body shape to predict your body fat percentage. More information is needed about the accuracy of these methods. Multi-compartment models are considered to be the most accurate method of body composition assessment 3 , These models split the body into three or more parts.
