AbstractThe study aimed to assess: (1) differences in nutritional status and lung function between CF patients and the control group; (2) differences in body composition and lung function between groups of patients with CF designated by type of mutation; (3) the relationship between lung function and body composition in CF patients.We studied 37 CF patients aged 19 to 51 years, and 41 healthy non-CF volunteers. Nutritional status was evaluated based on the BMI and the bioelectrical impedance analysis. The lung function was described by FEV1%. CF patients were classified according to the CFTR genotype based on five classes of mutations. BMI were lower in CF patients compared to reference group (women: Z = 3.76, p <0.001, men: Z = 3.06, p = 0.002). CF patients had a lower mean content of particular body components, as well as FEV1% values. BMI differed significantly depending on the type of mutation in females (H = 10.33, p = 0.006) and males (H = 8.26, p = 0.016). The lowest values of BMI were observed in the group of patients with severe types of mutations. Also, variables describing body composition were statistically significantly lower in patients with a severe type of mutations. The CFTR gene mutation type statistically significantly differentiated FEV1% (H = 23.22, p <0.000). The results of the logistic regression analysis showed that the likelihood of dropping FEV1% below the norm was twice as high in undernourished females and males. To assess the nutritional status of CF patients, more informative methods describing the proportions of body components are required.

Body composition assessment is an important tool in both clinical and research settings able to characterize the nutritional status of individuals in various physiologic and pathologic conditions. Health care professionals can use the information acquired by body composition analysis for the prevention and treatment of diseases, ultimately improving health status. Here we describe commonly used techniques to assess body composition in healthy individuals, including dual-energy x-ray absorptiometry, bioelectrical impedance analysis, air displacement plethysmography, and ultrasonography. Understanding the key underlying concept(s) of each assessment method, as well as its advantages and limitations, facilitates selection of the method of choice and the method of the compartment of interest.

The Relationship

Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of fourteen fortnightly assessments (BIA and biometry). After euthanasia, the following parts were weighed: whole carcass with the head, fillet, and skin (WC); fillet with skin (FS); and the remainder of the carcass with the head (CH). Together, FS and CH were ground and homogenized for the bromatological analyses. Estimates of the body composition and yields of tambatinga, with models including ichthyometric and BIA variables, showed correlation coefficients ranging from 0.81 (for the FS yield) to 1,00 (for the total ash). Similarly, models that included only BIA variables had correlation coefficients ranging from 0.81 (FS and CH yields) to 0.98 (for the total ash). Therefore, in tambatinga, the BIA technique allows the estimation of the yield of the fillet with skin and the body composition (water content, fat, ash, and protein). The best models combine ichthyometric and BIA variables.

Abstract Nutrition has an important role in the management of inflammatory bowel disease (IBD) and metabolic syndrome (MS). The goal of this study was to assess the nutritive status of patients treated with IBD and metabolic syndrome in the Gastroenterology Centre, Pauls Stradiòð Clinical University Hospital. Body bioelectrical impedance analysis (BIA) using GENIUS 220 PLUS (Jawon Medical) was used to determine Body Mass Index (BMI) kg/m², Metabolic Body Fat (MBF) kg, Soft Lean Mass (SLM) kg, Total Body Water (TBW) kg, body composition, metabolic type, Basal Metabolic Rate (BMR) kcal, and total Energy Expenditure (TEE) kcal in patients with IBD and metabolic syndrome and in a similarly aged control group. The obtained data showed that BMI was not correlated with MBF, BTW and Lean Body Mass (LBM). Patients with Crohn’s disease (CD) had normal value of BMI (M 24.3 kg/m²; F 20.2kg/m²), but we found variety-specific differences in body composition that confirmed deficiency or increase of specific body parameters. The performed prospective study confirmed the importance of the more precise nutritional status analysis, as it was clinically useful for the nutritional management of IBD. Patients with CD had expressed nutrient deficiency, sarcopenia, and reduced amount of proteins and minerals. For patients with MS, sarcopenia was present despite obesity.

AbstractBackgroundYoung ballet dancers are at risk of health issues associated with altered nutritional status and of relative energy deficiency in sport compared to the general population.AimTo evaluate the nutritional status and body composition in ballet dancers.Materials and methodsThe study group consisted of 40 young ballet dancers (mean age 19.97 years). Height and weight were measured and body mass index was calculated in all subjects (mean BMI value 19.79 kg/m2, SD: 2.051). Body composition was estimated using the bioelectrical impedance method.ResultsThe dancers’ fat-free mass was 47.33 kg (SD: 5.064) and, on the average, body fat represented the 15.92% (SD: 16.91) of their body weight.ConclusionsBallet dancers, who usually show significantly lower BMI values compared to the general population, also displayed body fat values under the suggested range. Some screening for altered nutritional status should be performed. In addition, education programs should be recommended in young ballet dancers, in order to inform about energy and nutrition requirements for health and training and to prevent malnutrition-related problems.

The aim of the paper was to asses changes in body composition using bioelectrical impedance analysis (BIA) methodology in members of national karate team after teen week preparatory training period. The investigation was carried out on 11 male karate contestants, aged 18 to 28 years mean age (21.82± 3.58). The body composition was analyzed with In Body 720. The BIA outcomes were divided in 3 group of variables: body fluid and body composition variables, obesity diagnose variables and segmental analysis variables. All BIA variables were insignificantly higher at second measuring (p>005). Only Body mass index (BMI=24.1 vs 24.55); mineral (4.69 kg vs 4.77 kg) and osseous (3.85 kg vs 3.92 kg), were significantly higher (p≤0.05) after preparatory period. Body fat mass (BFM=10.34 kg vs 10.75 kg, p=0.329) and body fat percent (BF%= 12.73 vs13.22%) insignificantly increased after preparatory period. The skeletal mass has changed from 40.03kg to 40.55kg (p=0.276). Body composition analysis, changes in weight, BMI and body fluids are essential for weight categories dependent sports such as karate. Positive changes in body components and in body fluids suggest that the training process during the preparatory period did not show negative effects on body components and the hydration of the karate athletes.

Human Body Composition

This study 1) further validated the relationship between total body electrical conductivity (TOBEC) and densitometrically determined lean body mass (LBMd) and 2) compared with existing body composition techniques (densitometry, total body water, total body potassium, and anthropometry) two new electrical methods for the estimation of LBM: TOBEC, a uniform current induction method, and bioelectrical impedance analysis (BIA), a localized current injection method. In a sample of 75 male and female subjects ranging from 4.9 to 54.9% body fat the correlation between LBMd and LBM predicted from TOBEC by use of a previously developed regression equation was extremely strong (r = 0.962), thus confirming the validity of the TOBEC method. LBM predicted from BIA by use of prediction equations provided with the instrument also correlated with LBMd (r = 0.912) but overestimated LBM compared with LBMd in obese subjects. However, no such systematic error was apparent when new prediction equations derived from this heterogeneous sample of subjects were applied. Thus the TOBEC and BIA methods, which are based on the differing electrical properties of lean tissue and fat and which are convenient, rapid, and safe, correlate well with more cumbersome human body composition techniques.

The aim of this study was to investigate body composition in patients with COPD using two methods, Quételet index and bioelectrical impedance analysis (BIA), and to compare their diagnostic values.Methods. The study included 198 patients with COPD admitted to the Territorial Teaching hospital No.2, and 28 healthy volunteers. According to COPD severity,  patients were divided into 4 groups; healthy volunteers (n = 28) were included in  the control group. All groups were matched for sex and age. Anthropometry with  body mass index (BMI) calculation and BIA were done in all participants.Results. The lowest average BMI was found in patients with severe and very severe COPD. Patients with infrequent exacerbations without decreased BMI had  reduction in fat-free mass (FFM) in 12.3% (n = 25); 14.1% patients (n = 28) had  increased body fat mass and decreased FFM. According to BIA results, reduction of  FFM was seen significantly more often than reduction of BMI (57.6% vs 30%; χ2=  58.71; p = 0.03). BIA parameters describing muscle tissue were significantly  related to the severity of bronchial obstruction (FEV1).Conclusion. Investigation of body composition using BIA method should be used  as a tool for comprehensive examination of COPD patients, for personalized choice  of treatment and in rehabilitation programs.
