“…Other measures, such as skin‐fold thickness, waist circumference, or waist‐to‐hip ratio (WHR) estimate abdominal fat mass, whereas body impedance analysis (BIA) provides an estimate of the total amount of adipose and muscle tissue in the body . However, the accuracy of anthropometric methods and their capability to differentiate subcompartments, such as visceral versus subcutaneous fat, is limited . Accordingly, imaging methods that directly depict body fat and muscle volumes are being used increasingly.…”

Purpose: To determine age-and gender-dependent wholebody adipose tissue and muscle volumes in healthy Swiss volunteers in Dixon MRI in comparison with anthropometric and bioelectrical impedance (BIA) measurements. Methods: Fat-water-separated whole-body 3 Tesla MRI of 80 healthy volunteers (ages 20 to 62 years) with a body mass index (BMI) of 17.5 to 26.2 kg/m 2 (10 men, 10 women per decade). Age and gender-dependent volumes of total adipose tissue (TAT), visceral adipose tissue (VAT), total abdominal subcutaneous adipose tissue (ASAT) and total abdominal adipose tissue (TAAT), and the total lean muscle tissue (TLMT) normalized for body height were determined by semi-automatic segmentation, and correlated with anthropometric and BIA measurements as well as lifestyle parameters. Results: The TAT, ASAT, VAT, and TLMT indexes (TATi, ASATi, VATi, and TLMTi, respectively) (L/m 2 6 standard deviation) for women/men were 6.4 6 1.8/5.3 6 1.7, 1.6 6 0.7/1.2 6 0.5, 0.4 6 0.2/0.8 6 0.5, and 5.6 6 0.6/7.1 6 0.7, respectively. The TATi correlated strongly with ASATi (r > 0.93), VATi, BMI and BIA (r > 0.70), and TAATi (r > 0.96), and weak with TLMTi for both genders (r > -0.34). The VAT was the only parameter showing an age dependency (r > 0.32). The BMI and BIA showed strong correlation with all MR-derived adipose tissue volumes. The TAT mass was estimated significantly lower from BIA than from MRI (both genders P <.001; mean bias -5 kg). Conclusions: The reported gender-specific MRI-based adipose tissue and muscle volumes might serve as normative values. The estimation of adipose tissue volumes was significantly lower from anthropometric and BIA measurements than from MRI.

“…Namely, different manufacturers of BIA analysers treat the underlying regression equations as business secrets, which is not likely to change, and therefore BIA (as a method on its own) lacks thorough scientific evaluation. To avoid this limitation, some authors have suggested the use of direct BIA measures, thus impedance and resistance values [16, 39]; yet, cut-off impedance and resistance values for underweight, normal weight, overweight, and obese subjects, standardised to a selected reference method, are currently not available. Last, in the present study, UWW could not be reliably performed in some subjects due to their inability to perform a full underwater exhalation, although no non-swimmers were included.…”

“…These, however, are not methods that can usually be performed in the field. Not surprisingly, new field methods, such as bioelectrical impedance analysis (BIA), have gained popularity [12], although the validity of BIA measurements has been questioned [13][14][15], and thorough scientific evaluation of the method is difficult to perform as different BIA analysers are being used and their underlying equations are inaccessible [16].…”

Objective: Several methods for the assessment of body composition exist, yet they yield different results. The present study aimed to assess the extent of these differences on a sample of young, healthy subjects. We hypothesised that differences in body composition results obtained with different methods will vary to the extent that a subject can be misclassified into different nutritional categories. Research Methods and Procedures: Underwater weighing (UWW), bioelectrical impedance analysis (BIA), anthropometry (ANT), and dual-energy X-ray absorptiometry (DXA) were used to assess body composition. An extensive list of ANT regression equations (or sets of equations) was analysed in terms of accuracy and precision relative to DXA. Results: When DXA-determined body fat (BF) values were taken as a reference, UWW overestimated BF in both genders. In contrast, BIA (measured with a given bioimpedance analyser) underestimated BF in females, although BIA-determined BF did not differ from DXA in males. A huge difference in BF estimates (8-29% for females and 6-29% for males, for DXA-determined BF of 25.5% and 13.9% for females in males, respectively) was observed across a number of ANT regression equations; yet, ANT proved not to be inferior to DXA, provided that regression equations with the highest combinations of accuracy and precision were chosen. Conclusions: The study proved grounds for comparison of body composition results of young, healthy subjects, obtained with different methods and across a wide range of ANT regression equations. It also revealed a list of the most appropriate ANT regression equations for the selected sample and reported their accuracy and precision.

Rationale: the use of anti-TNFα therapy, such as Infliximab (IFX), in patients with Chron's disease (CD) can lead to changes in body composition. Objective: to evaluate the body composition and functional capacity of patients with CD. Method: Cross-sectional study with patients with CD in clinical remission using IFX. For anthropometric evaluation, it was measured: weight, height and waist circumference; functional capacity by the hand grip strength test and body composition by bioelectric impedance. After that, the fat-free mass index and body fat index were calculated. Continouns variables were analyzed by Pearson or Spearman coefficient. For the multiple linear regression model, the time of use of IFX was used as a dependent variable and waist circumference, fat-free mass index, phase angle and handgrip strength were used as independent variables. Results: forty-three patients were evaluated, with an average of 43.1± 13.5 years of age. Of the total, 44.2% were overweight and 44.2% had increased waist circumference, 58.1% were classified with high to very high fat-free mass, 30.2% were below the adequacy parameter for fat-free mass index and 11.6% had reduced functional capacity. Conclusion: overweight, as well as increased waist circumference and body fat, is common in CD patients in clinical remission using Infliximab. Most patients had preserved functional capacity, however there wasn’t association with time of use of IFX.
