“…The objective of this study was to observe changes in the visceral fat index after the intervention and their relationship with eating habits and functional capacity, which, as the literature demonstrates, are associated with an increased risk of morbidity [3, 6, 27]. Being female, fruit consumption, gain in leg strength and flexibility have been shown to be predictors of visceral fat reduction.…”

Introduction: Nowadays, obesity is one of the main causes of death and disability. In recent years, it has been shown that the excess and distribution of body fat increases morbidity, with excess visceral fat being the most important factor that triggers pathologies. Thus, estimation of visceral fat makes it possible to identify patients with a higher cardiovascular risk, aiding the management of obesity. The main objective of the study was to identify predictors of the visceral fat index through a lifestyle intervention and to observe the effect of the intervention on dietary habits and functional capacity. Methods: A randomized intervention, parallel-group study was made. This study included 97 obese and overweight people (control group, n = 48; experimental group, n = 49) with a low socioeconomic status in an 8-month lifestyle intervention. Anthropometric, fitness and nutritional tests were assessed. Results: It was found that being female, eating the recommended daily portions of fruit, gaining strength in the legs and gaining flexibility are factors predictive of a lower visceral fat index. Age over 45 years and eating the recommended weekly portions of cereals and meats, fat and processed meats increases the visceral fat index after a lifestyle intervention. There were changes in the visceral fat index and in the different physical condition variables, but not in eating habits. Conclusion: A multicomponent lifestyle intervention reduces the visceral fat index; age over 45 and consuming cereals and meat increases the visceral fat index.

“…BIA predicts body fat quantity from impedance as well as other factors such as age, sex, height, and weight. Of the BIA techniques included in this meta‐analysis, only the ViScan device (Tanita AB‐140; Tanita Corp., Tokyo, Japan) attempted to measure impedance across the abdomen. The other techniques used hand‐to‐foot or foot‐to‐foot electrode configurations, quantifying impedance across the total or lower body, respectively.…”

Objective: This meta-analysis aimed to assess the agreement between intra-abdominal adipose tissue (IAAT) quantified by alternative methods and the reference standards, computed tomography (CT) and magnetic resonance imaging (MRI). Methods: MEDLINE and EMBASE electronic databases were systematically searched to identify studies that quantified IAAT thickness, area, or volume by a comparator method and CT or MRI. Using an inverse variance weighted approach (random-effects model), the mean differences and 95% limits of agreement (LoA) were pooled between methods. Results: The meta-analysis included 24 studies using four comparator methods. The pooled mean differences were −0.3 cm (95% LoA: −3.4 to 3.2 cm; P = 0.400) for ultrasound and −11.6 cm 2 (95% LoA: −43.1 to 19.9 cm 2 ; P = 0.004) for bioelectrical impedance analysis. Dual-energy x-ray absorptiometry (DXA) quantified both IAAT area and volume with mean differences of 8.1 cm 2 (95% LoA: −98.9 to 115.1 cm 2 ; P = 0.061) and 10 cm 3 (95% LoA: −280 to 300 cm 3 ; P = 0.808), respectively. Conclusions: Ultrasound and DXA measure IAAT with minimal bias from CT or MRI, while bioelectrical impedance analysis systematically underestimates IAAT. However, with the exception of DXA for IAAT volume, the wide LoA caution against clinical or research use of the comparator methods and emphasize the need to optimize alternatives to the reference standards.

“…(range: 1‐59 a.u.). As stated by the manufacturer, the intra‐abdominal adipose tissue or visceral adipose tissue (VAT) area measured by computed tomography in centimeters squared corresponds to the visceral fat arbitrary units obtained by the ViScan multiplied by 10 . We categorized participants into quintiles according to body adiposity measures.…”
