Summary: Combining traditional BIA with BIVA(specific) parameters can improve the accuracy of predicting body composition in children, effectively explaining the variability in fat-free mass and fat mass. This approach may be useful for pediatric patients.

Summary: This study aimed to improve the accuracy of body composition assessment in children with obesity through the use of bioimpedance technology, resulting in a predictive equation that reduced bias in FFM and FM measurements. By comparing the BIA outputs to a validated model of ADP adjusted by FFM density, the new equation significantly enhanced agreement with the 4-compartment model and eliminated the trend of increasing bias with higher FM and FFM levels.

Summary: This study aimed to establish age- and gender-specific reference curves for body fat mass, skeletal muscle mass, fat-free mass, and percent body fat in Czech children aged 6-11 years. The results showed that boys had peak values of BFM and %BF around the age of 11, while girls displayed a different pattern of age-related changes. This study provides valuable information for evaluating body composition in Czech children and for comparison with global studies.

Summary: The study found that birthweight z-score (BWZ) was positively associated with fat-free mass (FFM), height, fat-free mass index (FFMI), fat mass (FM), and fat mass index (FMI) at 3 years of age. Additionally, newborn fat-free mass (FFM) was positively associated with FFM, height, FFMI, and FM at 3 years, while newborn fat mass (FM) showed positive trends with FM and FMI at 3 years of age.

Summary: The study found that acutely violating BIA measurement assumptions does not significantly alter predicted percent fat mass values across different conditions, especially under different body mass index categories. Although women may experience larger percent fat mass differences than men during dehydration, overall the errors were relatively small.

Summary: The study evaluated the role of PhA in diabetes in older adults and found that men with PhA <= 4.9 were more likely to have diabetes, which was associated with oral hypoglycaemic agents. No significant relationship between PhA and diabetes was found in women. Further research is needed to determine the potential of PhA as a prognostic tool for diabetes.

Summary: An estimation equation for abdominal subcutaneous fat area (SFA) was established using bioimpedance analysis (BIA) combined with sagittal abdominal diameter (SAD). The equation showed high accuracy in estimating SFA at different levels of obesity. This study provides a simple, reliable, and practical measurement for epidemiological studies and individual SFA measurement.

Summary: This study analyzed the relationship between body composition and bioelectrical variables in 6801 children and adolescents aged 8-20 years. The findings showed that classic and specific bioelectrical impedance vector analysis (BIVA) agreed well with the evaluation of body composition using dual-energy X-ray absorptiometry (DXA) or bioimpedance spectroscopy (BIS), providing valuable tools for growth studies, malnutrition prevention, and athlete performance monitoring.

Summary: This study evaluated the ability of bioelectrical impedance technology to predict fat-free mass in infants and found that the addition of the impedance index improved prediction accuracy, although to a limited extent. Prediction using mixture theory was inaccurate and not recommended for use in infancy.

Summary: This study evaluated the agreement between bioelectrical impedance analysis (BIA) and air displacement plethysmography (ADP) for assessing body composition in children. The results showed that BIA underestimated fat mass and overestimated fat-free mass in normal weight children, while the opposite trend was observed in children with obesity. The agreement between the two methods in measuring fat mass and fat-free mass was strong. Overall, the BIA device is a valid tool for assessing body composition in Chinese preschool children.

Summary: About one-fourth of hospitalized COVID-19 patients were malnourished, and they showed worse outcomes in terms of needing invasive mechanical ventilation, in-hospital mortality, and duration of hospital stay compared to non-malnourished patients.

Summary: The study investigated the potential of standing 8-electrode BIA devices for assessing visceral fat area (VFA) and body fat mass (BFM) in athletes. The results showed strong agreement in BFM measurements compared to the reference method, but weaker agreement in VFA assessments, indicating a need for improvement in evaluating athletes' VFA.

Summary: This study described the Resistance and Reactance values obtained by BIA in a cohort of Italian patients with mild to severe obesity, and found a significant association between these values and BMI, sex, and age. The results provide a basis for developing new equations adapted for patients suffering from obesity.
