Body composition during growth in children: limitations and perspectives of bioelectrical impedance analysis

There are a number of differences between the body composition of children and adults. Body composition measurements in children are inherently challenging, because of the rapid growth-related changes in height, weight, fat-free mass (FFM) and fat mass (FM), but they are fundamental for the quality of the clinical follow-up. All body composition measurements for clinical use are 'indirect' methods based on assumptions that do not hold true in all situations or subjects. The clinician must primarily rely on two-compartment models (that is, FM and FFM) for routine determination of body composition of children. Bioelectrical impedance analysis (BIA) is promising as a bedside method, because of its low cost and ease of use. This paper gives an overview of the differences in body composition between adults and children in order to understand and appreciate the difference in body composition during growth. It further discusses the use and limitations of BIA/bioelectrical spectroscopy (BIA/BIS) in children. Single-frequency and multi-frequency BIA equations must be refined to better reflect the body composition of children of specific ethnicities and ages but will require development and cross-validation. In conclusion, recent studies suggest that BIA-derived body composition and phase angle measurements are valuable to assess nutritional status and growth in children, and may be useful to determine baseline measurements at hospital admission, and to monitor progress of nutrition treatment or change in nutritional status during hospitalization.

“…The results, indicating a higher TBW in obese patients were received by Resende et al, studying a group of people aged 10-19 [23]. Higher TBW in obese women compared to women of normal weight was also described in the study of Silva et al, who examined a population of 371 women [24].…”

Introduction: Disturbances in hydration status can increase the frequency of post-operative pain, nausea and vomiting (PONV), complicate the wound healing process and thus, increase the period of hospitalization, especially in overweight and obese patients. Aim of the research: To assess the impact of the standard and low-pressure pneumoperitoneum on hydration status of obese female patients undergoing laparoscopic cholecystectomy in the early post-operative period. Material and methods:The study included 52 female individuals with asymptomatic cholelithiasis who underwent laparoscopic cholecystectomy. Patients were assigned to three groups according to the body mass index and value of intraabdominal pressure. Evaluation of the hydration status was performed at three time points: point 0 -before the operation, point 24 -24 hour after the surgery, and point 48 -48 hours after the surgery. Results: A higher total body water (TBW) and dehydration was observed in obese compared to normal weight patients in the time point 24 and 48. Extracellular water (ECW) was significantly higher in obese compared to normal weight patients in the time studied time point. Intracellular water (ICW) and ECW/ICW did not differ significantly between the studied groups in the studied time. Conclusions: Obesity alters the hydration status. Values of carbon-dioxide pneumoperitoneum pressure used during short duration laparoscopic surgery did not have an influence on the hydration status of the obese female patients.

Background & Aims:Considering that obese adolescents present alterations in the quantity of body water, fat and lean body mass, specific formulae need to be adjusted through a reference method. This study aimed to describe and compare the body composition data obtained by bioelectrical impedance analysis (BIA) and the deuterium oxide dilution method (DODM). To identify possible correlations and agreement between these two techniques and adjust linear regression models for the prediction of DODM values on the basis of BIA results. Methods: Anthropometric measurements were accomplished for obese adolescents, and their body composition was assessed by the BIA and DODM techniques. Results: Compared to the DODM technique, BIA overestimated the fat-free mass (FFM) and the total body water (TBW) and underestimated the fat mass (FM). There was a significant positive correlation but no agreement between the FFM (kg), FM (kg), and TBW (L) data achieved via DODM and BIA. The application of linear regression model adjustments to the values measured by BIA enabled prediction of the DODM values for body composition in obese adolescents. Conclusion: These formulas have been demonstrated to improve the agreement between the two methods, so a more accurate tool that is closer to the DODM reference technique has been made available for use in clinical practice.
