Clinical Nutrition

Vector bioimpedance analysis (BIVA) shows different vector positions of obese (O), sarcopenic (S), and obese sarcopenic (S-O) subjects, with a longer vector length indicating greater fat mass in the O and S-O groups, and a lower phase angle in the S group.

BMI is not the most useful parameter for estimating fat mass (FM). Hip circumference and FM, obtained by anthropometric analysis and BIA, show a better association with FM obtained by DXA.

This study compares the analysis of hydration status using conventional bioimpedance analysis (BIA) and BIA vector analysis (BIVA) in women with moderate and severe obesity. The impedance vector distribution followed a clear pattern, with progressive shortening as BMI increased.

International journal of obesity and related metabolic disorders

The vector shift in the bioimpedance plot in obese subjects distinguishes weight loss due to fluid removal (longer vector) from weight loss due to a high-calorie restrictive diet (vector does not shift).

Nutrients

In all BMI classes, women have lower concentrations of Vitamin D (25OHD) than men, and these concentrations are inversely correlated with fat mass %. It is possible that differences in body composition between genders may influence Vitamin D deficiency.

Clinical Nutrition

This huge observational study including over 8,000 bioimpedance measurements on as many obese subjects, turns out to be the largest Italian study on body composition in obese subjects.
Thanks to this landmark study, new norms have been defined on specific bioelectrical parameters for subjects with BMI> 30, setting the basis for the development of new equations adapted for patients suffering from obesity. The prevalence of low muscle condition has been analyzed and new ways of interpreting body composition data trough bioimpedance analysis in severe obese patients have been discussed.

Nutrients

Phase angle (PhA) is a predictor of inflammation status in patients with low level of 25-Hydroxi-vitamin D and enables to stratify obese patients at risk that could take advantage from an accurate supplementation.

BIVA analysis enables evaluation of the efficacy of resistance training programmes. Physical exercise carried out three times a week favours a more significant improvement in body composition parameters such as Phase Angle (PhA) and the handgrip strength test than the same programme performed once a week.
