“…Therefore, we are confident that main findings persist. Moreover, additional calculations to estimate fluid overload are useful, as various studies have shown correlations between BIA derived fluid overload and outcome of disease [49,55,56]. The PA is calculated directly from reactance and resistance and is therefore less directly influenced by fluid overload, although theoretically, rapid fluid shifts can contribute to cell damage and, therefore, decrease PA [22].…”

Association of bioelectric impedance analysis body composition and disease severity in COVID-19 hospital ward and ICU patients: The BIAC-19 study

Background: The current severe acute respiratory syndrome coronavirus 2 pandemic is unprecedented in its impact. It is essential to shed light on patient characteristics that predispose to a more severe disease course. Obesity, defined as a BMI>30 kg/m 2 , is suggested to be one of these characteristics. However, BMI does not differentiate between fat mass and lean body mass, or the distribution of fat tissue. The aim of the present study was to assess the body composition of COVID-19 patients admitted to the ward or the ICU and identify any associations with severity of disease. Methods: We performed an observational cross-sectional cohort study. Bioelectric impedance analysis was conducted amongst all confirmed COVID-19 patients admitted to the ward or ICU of our hospital in the Netherlands, between April 10 and 17, 2020. Body water measurements and derived values were recalculated to dry weight, using a standard ratio of extracellular water to total body water of 0.38. Data were compared between the ward and ICU patients, and regression models were used to assess the associations between baseline characteristics, body composition, and several indicators of disease severity, including a composite score composed of mortality, morbidity, and ICU admission. Results: Fifty-four patients were included, of which 30 in the ward and 24 in the ICU. The mean age was 67 years (95%-CI 64e71), and 34 (63%) were male. Mean BMI was 29.7 (95%-CI 28.2e31.1) kg/m 2 and did not differ between groups. Body composition values were not independently associated with disease severity. In multiple logistic regression analyses, a low phase angle was associated with COVID-19 severity in the composite score (OR 0.299, p ¼ 0.046). Conclusion: We found no significant associations between body composition, including fat mass, visceral fat area, and fat-free mass, and disease severity in our population of generally overweight COVID-19 patients. A lower phase angle did increase the odds of severe COVID-19. We believe that factors other than body composition play a more critical role in the development of severe COVID-19.

“…Furthermore, excessive ECW may be estimated more accurately by factoring in increases in ECW with age. This method may allow us to quantitatively evaluate excessive ECW not only in patients with HD but also in patients with abnormal body water distributions (e.g., those with CKD, HF, and critical illness [8,14,18]).…”

“…Previously, ECW/TBW was used as a classification index of excessive fluid volume regarding mortality in patients with chronic kidney disease (CKD), heart failure (HF), or critical illness [8]. In addition, ECW/TBW of healthy subjects, measured by MF-BIA, was used as an index of body water distribution to estimate appropriate body weight, that is, dry weight in patients undergoing HD who cannot self-regulate body water content [9,10].…”

Characteristics of body water distribution in healthy adults measured by multi-frequency bioelectrical impedance analysis

et al. 2019

To investigate the characteristics of the ratio of extracellular water (ECW) to total body water (TBW) volume (ECW/TBW) in a large group of healthy adults, measured by multi-frequency bioelectrical impedance (bioimpedance) analysis (MF-BIA). Subjects and methods: The correlation between ECW and TBW was studied in 957 healthy adults who underwent general medical examinations. Differences between measured and predicted ECW from ECW-TBW correlation equations (ΔECW) were calculated, and possible factors for non-zero ΔECW were explored. To investigate the influence of percent fat mass (%FM) on ECW/TBW, the ECW/TBW values of "lean" and "obese" groups, classified by %FM, were compared. ECW/TBW was also compared between "non-obese" and "obese class I-II" groups, classified by the body mass index for both genders. Results: ECW and TBW showed strong positive correlations in both genders. ΔECW was within ±0.2 L and increased with advancing age; ECW/ TBW also increased. There were no significant differences in ECW/TBW between the "lean" and "obese" groups in either gender, or between the "non-obese" and "obese class I-II" groups in the female group. Conclusions: ECW/TBW measured by MF-BIA was considered to be an index of body water distribution in healthy adults ranging from "lean" to "obese class I-II," which is not significantly affected by body fat.

“…Bioelectrical impedance analysis (BIA) is widely used in the clinical setting for the evaluation of nutritional status and fluid status (17,18). BIA is a simple, noninvasive, rapid, portable, and convenient method, which indirectly estimates the body composition and fluid distribution by sending a weak electric current throughout the body (19).…”

Clinical characteristics of hyponatremia in patients receiving nutrition support : A cross-sectional study evaluated by bioelectrical impedance analysis

et al. 2021

View full text Add to dashboard Cite

Background & aims : We investigated the contributing factors of hyponatremia in patients on nutrition support using bioelectrical impedance analysis (BIA). Methods : Thirty patients administered enteral or parenteral nutrition support for at least 72 hours were studied. We collected nutritional and electrolyte intake, serum biochemical parameters, and body composition measured by BIA. Patients were classified into two groups according to their serum sodium levels : (1) Normanatremia group, 135-145 mEq / L (n = 18) and (2) Hyponatremia group, less than 135 mEq / L (n = 12), and their characteristics were analyzed. Results : There were no significant differences between the Normonatremia and Hyponatremia groups in terms of energy, protein, and sodium intake. Serum biochemical parameters other than serum sodium and chloride levels were comparable between the two groups. On the other hand, the ratio of extracellular water to total body water (ECW / TBW) obtained by BIA was significantly higher in the Hyponatremia group than in the Normonatremia group. Further, an elevated ECW / TBW significantly and negatively correlated with serum albumin level. Conclusions : Regardless of sodium intake, higher ECW / TBW was associated with hyponatremia in patients on nutrition support. ECW / TBW may be an important clinical parameter relevant to the nutritional care of hyponatremia.
