TLDR
BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction.Abstract:
OBJECTIVE: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. SUBJECTS AND METHODS: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. RESULTS: VF areas > 130 cm2 were more prevalent among the elderly and among men. Adult females showed a stronger correlation between GV and %TBF-BIA. The other groups showed similar results and statistically significant correlations. Correlations between GV and phase angle were weak and not statistically significant. ROC Curves analyzes showed the following %TBF-BIA, which identified excess VF: for male subjects: 21.5% (adults) and 24.25% (elderly); for female subjects: 35.05% (adults) and 38.45% (elderly) with sensitivity of 78.6%, 82.1%, 83.3%, and 66.7%, and specificity of 70.6%, 62.5%, 79.1%, and 69%, respectively. CONCLUSION: BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction.read more

CT assessment of nutritional status and lean body mass in gastric and esophageal cancer
Thais Manfrinato Miola,Elizabeth Launeir Santos da Conceição,Juliana de Oliveira Souza,Paula Nicole Vieira Pinto Barbosa,Felipe José Fernandez Coimbra,Almir Galvão Vieira Bitencourt +5 more
TL;DR: A substantial portion of patients with gastric and/or esophageal cancer exhibited low lean body mass on computed tomography, and among the tested anthropometric parameter, mid-arm muscle circumference showed the best agreement with CT-measuredLean body mass.

Association between occupational stress, work shift and health outcomes in hospital workers of the Recôncavo of Bahia, Brazil: the impact of COVID-19 pandemic
TL;DR: In this article , a longitudinal study was conducted with 218 hospital workers over 18 years old to ascertain the level of occupational stress before and during the COVID-19 pandemic, how it changed and its association with health outcomes of hospital workers in the Recôncavo of Bahia, Brazil.

Evaluation of a Leg-to-Leg Bioimpedance Device in the Estimation of Abdominal Visceral Fat for the Elderly – Comparison with CT
Cheng-Chyuan Lai,Hsueh-Kuan Lu,Li-Ming Chiang,Jasson Chiang,Kuen-Chang Hsieh,Chung-Liang Lai +5 more
TL;DR: The results showed that each obese group all has large LOA when compared with the CT reference values, suggesting that the LBIA accuracy for estimating VFA is limited in the Chinese elderly population.

The Prediction of Human Abdominal Adiposity Based on the Combination of a Particle Swarm Algorithm and Support Vector Machine
TL;DR: A new prediction method based on an improved support vector machine (SVM) improves the prediction accuracy and reduces the sample size dependence of the algorithm, which can provide a reference for abdominal obesity.

Relation of Body Fat Distribution to Metabolic Complications of Obesity
TL;DR: In women, the sites of fat predominance offer an important prognostic marker for glucose intolerance, hyperinsulinemia, and hypertriglyceridemia, may be related to the disparate morphology and metabolic behavior of fat cells associated with different body fat distributions.

Anthropometric measurements in the elderly: age and gender differences.
TL;DR: In the elderly the oldest subjects showed a thinner body frame than the youngest of both genders, and there was a more marked fat redistribution in women, suggesting that visceral redistribution in old age predominantly affects females.

Bioelectric impedance phase angle and body composition
TL;DR: The use of bioelectric impedance phase angle for predicting body composition was determined in 53 males and 69 females 9-62 y of age and may be useful for predicting %BF in clinical and survey research.

Determination of total adipose tissue and body fat in women by computed tomography, 40K, and tritium
TL;DR: It is concluded that the CT-based AT determination of adipose tissue volumes is the most reproducible method so far available and might turn out to be of great value in human energy balance experiments.
