Background: Low hand grip strength (HGS) is one of the criteria for diagnosing frailty and sarcopenia, it is associated with the risk of metabolic and mental diseases; Studies have shown that in patients with arterial hypertension (BP), low HGS represents a risk of incidence of cardiovascular disease and mortality, in addition to mortality from other causes; however, there are still no conclusive studies regarding the factors that determine HGS in BP. Objective: Identify the factors that influence low HGS in patients with BP. Material and methods: Cross-sectional, observational, analytical case-control study. 100 patients with a diagnosis and treatment of HTN were included, and 100 controls matched by age and sex. Demographic data, self-report of physical activity, weight, height, body composition, and HGS were obtained. Descriptive statistics, Chi-square, were performed to look for differences in means, Mann-Whitney U, Kruskal-Wallis, and Games-Howell post-hoc analysis. Results: The average age of the sample was 47.40 ± 0.54; The results of body composition between the study groups did not show statistically significant differences; However, different factors were found that influence HGS. Conclusions: Body composition is what determines HGS in patients between 30 and 60 years of age, however in patients with BP it is visceral fat that is responsible for low HGS.

Introduction: Patients with protein metabolism disorders (PMDs) require a diet with strict protein control that can affect their growth and development. The aim of the study was to assess nutritional status and growth in patients with PMDs undergoing dietary treatment. Patients and methods: Prospective observational case-control study in 63 patients with PMDs and 63 healthy controls matched for age and sex. We collected data for anthropometric variables (weight, height, BMI, tricipital and subscapular skinfolds, arm and waist circumference) and calculated the corresponding z scores. We also estimated the body fat mass and classified patients into nutritional status categories. Results: The overall analysis found a lower height z score in patients with PMDs and an equal proportion of overweight and obesity with respect to controls (30.2%). When we divided patients with PMDs into 2 groups (phenylketonuria and other aminoacidopathies), we found that patients with phenylketonuria had a height that was similar to the height of controls and significantly higher compared to patients with other aminoacidopathies. When it came to nutritional status, the prevalence of overweight and obesity was greater in the phenylketonuria group (45.5%), while underweight and short stature were more frequent in the group with other aminoacidopathies. Conclusion: Not all patients with PMDs follow the same growth pattern, and their body composition is variable. In our sample, the group of patients with phenylketonuria had an adequate height but also a higher prevalence of overweight and obesity. On the other hand, patients with other aminoacidopathies had a higher prevalence of underweight and lower z scores for height and arm circumference. Resumen: Introducción: Los pacientes con errores innatos del metabolismo de las proteínas (EIMP) requieren una dieta con control proteico estricto que puede condicionar su crecimiento y desarrollo. El objetivo del estudio es valorar el estado nutricional y crecimiento en pacientes con EIMP sometidos a tratamiento dietético. Pacientes y métodos: Estudio observacional prospectivo caso-control en 63 pacientes con EIMP y 63 controles sanos emparejados por edad y sexo. Se obtuvieron datos antropométricos de peso, talla, IMC, pliegues tricipital y subescapular, perímetros del brazo y cintura, y se calcularon sus z-score. Se estimó la grasa corporal y se clasificó el estado nutricional. Resultados: El análisis global mostró un z-score de talla inferior en pacientes con EIMP, e igual proporción de sobrepeso y obesidad respecto a controles (30,2%). Al dividir los pacientes con EIMP en dos grupos (fenilcetonuria y otras aminoacidopatías) se observó que los pacientes con fenilcetonuria tuvieron una talla similar a los controles y significativamente superior a los pacientes con otras aminoacidopatías. Al clasificar el estado de nutrición, la prevalencia de sobrepeso y obesidad fue superior en el grupo de fenilcetonuria (45,5%), mientras que los pacientes más desnutridos y con talla baja se encontraron en el grupo de otras aminoacidopatías. Conclusión: No todos los pacientes con EIMP siguen un mismo patrón de crecimiento y su composición corporal es variable. En esta muestra, los pacientes con fenilcetonuria tienen una talla adecuada y mayor incidencia de sobrepeso y obesidad. Sin embargo, otras aminoacidopatías presentan mayores tasas de desnutrición y menor z-score de talla y perímetro del brazo.

El síndrome de Down (SD) es un trastorno genético que conlleva una serie de problemas de salud, entre ellos, una reducción de la capacidad cardiorrespiratoria. En el caso de las personas con SD, resulta complicado conseguir una evaluación precisa de la composición corporal, debido a su singular morfología. Sin embargo, se trata de un componente crucial para la detección precoz de la obesidad y para el diseño de intervenciones específicas sobre los hábitos. Participaron en el estudio cuatro corredores varones con SD, que se sometieron a mediciones antropométricas y al análisis vectorial de impedancia bioeléctrica (modalidades clásica y específica) antes y después de completar la carrera de 14 kilómetros. Se emplearon varias ecuaciones para estimar la composición corporal. Asimismo, se hizo un análisis del somatotipo y se compararon los cambios bioeléctricos que provocó la carrera. Se reveló una variabilidad considerable en la composición corporal y el rendimiento en carrera de las personas con SD. Las diversas ecuaciones para estimar la masa grasa arrojaron resultados variables (del 4.2 al 33.3 %). En particular, se observó un patrón único en cada participante en cuanto a la cantidad de líquidos. El Participante 1 destacó con un ángulo de fase marcadamente alto (9.8°), mientras que los demás obtuvieron valores medios inferiores (4.5-6.3°). El análisis del vector de impedancia bioeléctrica indicó una pérdida normal de líquidos durante la carrera (T2 = 92.2; p < .0001). Resultó sorprendente que el Participante 1, el cual consiguió el menor tiempo de carrera, experimentase la pérdida de líquidos más significativa, pero mostrase una mayor retención de agua intracelular. Este estudio subraya la importancia de diseñar métodos de evaluación de la composición corporal adaptados a las personas con SD. El diseño de herramientas de evaluación precisas contribuirá a mejorar el bienestar de esta población en su búsqueda de estilos de vida activos. Estas conclusiones arrojan luz sobre la compleja relación entre composición corporal, hidratación y rendimiento en personas con SD.

Introduction: in colorectal cancer (CRC) surgery, preoperative nutritional factors are often overlooked or underestimated. This situation represents a significant deficiency that may negatively affect patients' postoperative recovery processes. Objective: the objective of this study was to evaluate the impact of preoperative malnutrition, sarcopenia, obesity, and dietary inflammatory potential on early postoperative outcomes in CRC. Methods: preoperative sarcopenia was identified using European Working Group on Sarcopenia in Older People (EWGSOP2) criteria based on skeletal muscle obtained from computed tomography (CT) scans, and malnutrition was identified using Global Leadership Initiative on Malnutrition (GLIM) criteria. Visceral and subcutaneous obesity were assessed using CT scans. The energy-adjusted dietary inflammatory index (E-DII) was calculated from dietary records. Results: a total of 121 patients were included in the study, and 45.5 % of them were malnourished according to GLIM, 15.7 % were sarcopenic according to EWGSOP2. Multivariate logistic regression analysis showed that sarcopenia [OR = 3.973 (1.028-15.353), p = 0.043], malnutrition [OR = 3.954 (1.479-10.575), p = 0.006], and E-DII [OR = 4.955 (1.397-17.571), p = 0.013] were independent risk factors for complications. Sarcopenia [OR = 6.894 (1.080-43.998), p = 0.041] was also risk factor for long-term hospitalization. Conclusion: a comprehensive evaluation of preoperative nutrition and related factors in CRC surgery, along with timely interventions, has the potential to significantly reduce postoperative complications and length of hospital stays.

The aim of this study was to determine the effects 12 weeks Step aerobics program on anthropometric characteristics and body composition in young females. A total of 94 female participants were randomly divided in two groups. The E group subsample consisted of 44 participants (20±0.4 years), who had three Step aerobics program trainings per week and the C group subsample consisted of 50 participants (20±0.6 years), who did not take part in any organized exercise program and only conducted their regular daily activities. The following measurements were used: Body height, body weight, waist size, abdomen skinfold, back skinfold, upper arm skinfold, upper leg skinfold, body fat percentage and muscle mass percentage. Upon the Step aerobics program implementation, there was a body fat reduction by 4.9 % and waist size by 7.7 %, while the muscle mass was increased by 9.4 %. Above mentioned skinfolds showed a reduction (p>0.05) at the final measurement compared to the initial one - abdomen by 25 %, upper leg by 23.7 %, back by 15.7 % and upper arm by 3.5 %. Likewise, there was a body fat percentage reduction by 2.1 % and BMI by 6.4 %. Based on the obtained results, we can conclude that the Step aerobics training is efficient in reducing subcutaneous fat tissue and viscelar fat, as well as in increasing muscle mass.

This study aimed to determine differences in morphological characteristics and body composition between female handball players from the national teams of Montenegro and Kosovo (U16). Thirty-four participants were included in the study, divided into two subgroups. The first subgroup consisted of 18 players from the Montenegro national team, with an average age of 14.68±0.58 years. The second subgroup consisted of 16 players from the Kosovo national team, with an average age of 15.33±0.66 years. Testing was conducted during the qualification rounds for the European Championship took place in Podgorica in 2021. All players were assessed for anthropometric measurements and body composition, with a total of twelve variables. Body height, body weight, hand length, arm span, triceps skinfold, biceps skinfold, subscapular skinfold, abdominal skinfold, calf skinfold, thigh skinfold, body mass index (BMI), and body fat percentage (BF).The Tanita - model BC-418MA was utilized for the assessment of body composition. Differences in morphological characteristics and body composition of the female handball players from the two national teams were determined through discriminant parametric procedures using the T-test for independent samples with statistical significance set at p < .05. The results indicated that the players from the Montenegro team were significantly younger, had significantly greater average body height, body weight, and hand length compared to players from the Kosovo team. Statistical differences between the two treated teams were found in the variable thigh skinfold, while no significant differences were observed in BMI and BF. [ABSTRACT FROM AUTHOR]

The aim of this study was to establish an age-related dynamic of change model for predicting changes in body composition indicators in professional firefighters. The study included a total sample of 145 subjects, comprising professional firefighters from Serbia (Age: 36.6 ± 7.6 yrs., Min - Max: 21.0 - 52.0 yrs.). Four basic variables were analysed: Body Mass - BM, Body Fat Mass - BFM, Skeletal Muscle Mass - SMM, and Visceral Fat Area - VFA, as well as five derived, or index, variables: Body Mass Index - BMI, Percentage of Body Fat - PBF, Percentage of Skeletal Muscle Mass - PSMM, Protein-Fat Index - PFI, and Index of Body - IBC Composition. The results showed a statistically significant dynamic of change as a function of age for eight of the examined variables, while only one (Skeletal Muscle Mass - SMM) was not statistically significant. The highest statistical significance in terms of dynamics of change as a function of age was found for the variable VFA (F = 35.241, p = 000) and the variable PSMM (F = 31.398, p = 0.000). Professional firefighters in Serbia fall into the category of people with normal nutritional indicators. However, due to a dominant increase in visceral fat (VFA) combined with a dominant decrease in the proportion of skeletal muscles in the body (PSMM), it can be concluded that they are exposed to a risk of developing various chronic diseases, while their working conditions, which promote certain negative lifestyle habits, also contribute to the observed increase in body fat components.

Bioelectrical impedance analysis (BIA) is a non-invasive, economic and fast method for body composition assessment. Phase angle (PhA) is considered an indicator of cellular health and cell membrane integrity, and it seems to be related to physical capacity and performance. The aim of this study was to analyze the possible relationships between PhA and skeletal muscle mass percentage (SMM%) and between PhA and fat mass percentage (FM%) in a healthy Caucasian population with a wide age range. 210 healthy Caucasian participants (99 women and 111 men), aged 20-70 years were analyzed. A BIA foot-to-hand body composition analyzer (BIA-101, AKERN-Srl, Firenze, Italy) was used to determine bioelectrical parameters, and a whole body DXA scanner QDR, serie Horizon (Hologic Inc., Bedford, MA, USA) was used for SMM% and FM% assessment. Irrespective of age range, strong positive significant correlations were observed between PhA and SMM% (0.520-0.687; p < 0.01) and strong (or moderate/strong) negative significant correlations were observed between PhA and FM% (0.492-0.657; p < 0.01). These correlations indicate that PhA could be used as a marker to monitor the evolution of an active subject, whether an athlete or not. It would be useful to develop and validate new equations for skeletal muscle mass and fat mass assessment, which include PhA as a bioelectrical parameter. [ABSTRACT FROM AUTHOR]

Background: changes in body composition (BC) are common in interstitial lung disease, which leads to an increased risk of complications and infections, and are associated with poor quality of life and worse outcomes. BC assessment is important to identify malnutrition and sarcopenia. However, gold-standard techniques are not available in all clinical settings. Aims: this study aimed to evaluate the agreement and reliability of body composition estimated by bioelectric impedance analysis (BIA) and measured using dual-energy X-ray absorptiometry (DEXA) in women with interstitial lung disease. Methods: this is a cross-sectional study. BC (fat mass and appendicular skeletal muscle mass) were assessed using BIA multifrequency and DEXA in standardized conditions. Agreement and reliability between techniques were evaluated using Bland-Altman plots and the intraclass correlation coefficient (ICC). Results: a total of 50 women were evaluated. No differences were observed for FM (BIA, 25.8 ± 10.2 kg and DEXA, 26.3 ± 10.0 kg, p = 0.77) and ASMM (BIA, 14.1 ± 2.7 kg and DEXA, 13.9 ± 2.3 kg, p = 0.83). Based on ICC, good reliability was observed for FM (ICC, 0.98) and ASMM (ICC, 0.93). Conclusion: BC estimated by BIA showed good agreement and reliability with DEXA measurements. In the absence of this method, BIA can replace the DEXA technique for body composition assessment. [ABSTRACT FROM AUTHOR]

Introducción: Por mucho tiempo el índice de masa corporal (IMC) se ha utilizado por los trabajadores de la salud como un estándar para clasificar el estado nutricional, la cantidad de grasa y el riesgo de padecer enfermedades metabólicas; sin embargo, cada vez se reconocen más sus limitaciones. Objetivo: El objetivo de este trabajo era identificar si el IMC es un indicador confiable del estado de grasa corporal en adultos guatemaltecos. Metodología: Para determinar esto, se analizaron los datos de 781 adultos que asistieron a la clínica de Nutrición de Salud de la Universidad Francisco Marroquín (UFM) entre 2022 y 2023. Resultados: Se encontró que el IMC subestimó el estado de grasa corporal en al menos un 10 % de sujetos con respecto de la clasificación, según los índices de adiposidad medidos por DXA. Por otra parte, se encontró que la circunferencia de la cintura se correlacionó de forma significativa con el tejido adiposo visceral para mujeres y hombres (r=0.8608; p

La lactancia materna es la forma óptima de alimentación en las etapas tempranas de la vida. La Organización Mundial de la Salud (OMS) recomienda su práctica continua hasta los 6 meses, preferiblemente exclusiva, y prolongada hasta los 2 años, acompañando a una alimentación complementaria adecuada. Cuba posee una guía alimentaria para el niño menor de 2 años, que indica los momentos oportunos para introducir diferentes alimentos. El objetivo fue describir la alimentación complementaria en infantes lactados a pecho, valorar la seguridad alimentaria y determinar las asociaciones con el estado nutricional mediante indicadores antropométricos del crecimiento y composición corporal. Se realizaron encuestas de seguridad alimentaria y consumo de alimentos en 73 infantes entre 6 y 23 meses de vida, que mantuvieron lactancia materna exclusiva o predominante. El estado nutricional se evaluó por los patrones de la OMS, a partir de mediciones antropométricas, y la estimación de la composición corporal por isótopos estables, con las referencias del Organismo Internacional de Energía Atómica. Se realizó el procesamiento estadístico del total de la muestra y por grupos de edad. A pesar de observar inseguridad alimentaria leve en el 46,6% de los infantes, la alimentación fue variada en la mayoría, con un consumo diario de cereales, viandas, pan, lácteos y carnes. Se destacó la adición de aceites en las comidas, consumo de jugos envasados, pero poca representación de frutas y vegetales en su dieta habitual. El estado nutricional fue adecuado en más del 80% de los casos, pero no se asoció con el consumo de alimentos.

El objetivo del estudio fue evaluar la composición corporal de escolares de 6 a 11 años, matriculados en la enseñanza primaria I de escuelas municipales de una ciudad de Santa Catarina, Brasil. Participaron escolares de 1º a 5º grado, con un total de 804 niños para la muestra, 440 niñas y 364 niños, de edades comprendidas entre los 6 y los 11 años. Los instrumentos de investigación fueron mediciones antropométricas individuales para el cálculo del Índice de Masa Corporal (IMC) y el Índice de Adiposidad Corporal (IAC). Para el análisis y la interpretación de los datos obtenidos se utilizó el programa estadístico SPSS 20.0. Los resultados del IMC de la muestra fueron de 17,7 kg/m² y el IAC de 20,1%. Los varones presentaron valores inferiores de IMC (0,01 menos) y de IAC (0,03 menos). Al clasificar vemos que el 53% de la muestra se encuentra en "eutrofia", es decir, en el peso ideal según los valores del IMC (kg/m²). Lo mismo ocurre con el IAC (%). Observamos que 62% de la muestra está clasificada como "eutrófica". Se concluye que los alumnos de 6 a 11 años matriculados de 1º a 5º grado en escuelas municipales de una ciudad de Santa Catarina son mayoritariamente eutróficos.

El objetivo de este estudio fue determinar los efectos que tiene el sedentarismo en la composición corporal, condición física y rendimiento académico a lo largo de las etapas de Educación Primaria y Secundaria. La muestra incluyó 70 niños evaluados durante 5 años. Se obtuvieron datos de composición corporal (Índice de Masa Corporal, Índice de Cintura Cadera, % de grasa corporal y % de masa muscular), condición física (salto de longitud, salto de altura, Test de agilidad o Test de Tapping, Test de Cooper, presión manual) y rendimiento académico en cada asignatura cursada en ambas etapas educativas. Los resultados mostraron que a mayor edad existe un mayor número de alumnado con comportamiento sedentario, un empeoramiento de la condición física y, además, el rendimiento académico se ve afectado por estos comportamientos sedentarios y la inactividad física.

To take advantage of altitude, "intermittent hypoxia" methods have been developed that involve shorter exposures to hypoxia. In general, systemic hypoxia can be produced in two ways: (1) by lowering barometric pressure (BP, hypobaric hypoxia) or (2) by reducing the amount of oxygen in inspired air (FiO2) through oxygen filtration or nitrogen dilution (normobaric hypoxia). The objective of this analysis was to observe changes in body composition and aerobic performance after 8 weeks of intermittent hypoxia exposure at rest. A total of 20 male volunteers between the ages of 18-26 participated in the study. Participants were randomly divided into 2 groups (Control Group and Intermittent Hypoxia Group). The Intermittent Hypoxia Group completed the process by being exposed to intermittent hypoxia for 8 weeks. Each intermittent hypoxia session was planned as 3 days a week and for 1 hour. After 8 weeks of experimental process, statistically significant differences were found for lean mass, android lean mass, gynoid lean mass, the relative skeletal muscle mass index, peak lactate, 1mmol lactate threshold, 4mmol lactate threshold, and MaxVo2 variables (p<0,05). After 8 weeks of intermittent hypoxia exposure, an increase in maximal oxygen consumption capacity was observed. The increase in lean mass, especially in the gynoid and android regions, can be explained by the increase in fat burning activities due to oxygen utilization capacity. Almost every study reviewed in the literature used different intermittent hypoxia exposure protocols and different simulated altitudes. The method discussed in this study may be beneficial on the body composition and oxygen utilization capacity of sedentary individuals. [ABSTRACT FROM AUTHOR]

This study aims to investigate body typologies based on a combination of basic anthropo-morphological characteristics and body composition measured by multichannel bioimpedance in a sample from the adult population of Lebanon. A total of 302 subjects (173 males and 129 females) without acute or chronic health disorders were included in the study. Body composition was measured by the multichannel bioelectrical impedance (BIA) method, using the i30 device (MEDIANA, Korea). The research used 10 variables, including three basic anthropo-morphological variables, three for assessing fat, three for assessing the muscle component, and one index variable. K-means cluster analysis was used to define five specific clusters (5D) of body types based on sex. In light of the results, the study established five distinct clusters representing five different body typologies among Lebanese adults, categorized by sex: Male sample, Group 1 – Obese Endomorph (15.61 %), Group 2 – Balanced Mesomorph (16.76 %), Group 3 – Short Endomorph (30.06 %), Group 4 – Short Mesomorph (34.10 %), and Group 5 – Pathological Obese Endomorph (3.47 %); Female sample, Group 1– Obese Endomorph (2.33 %), Group 2 – Short Endo/Mesomorph (28.68 %), Group 3 – Short Ectomorph (32.56 %), Group 4 – Endomorph (22.48 %), and Group 5 – Balanced Mesomorph (13.95 %). Furthermore, the results indicated that the primary factor contributing to the distinctions among the identified clusters in terms of sex is fat tissue. This leads to the conclusion that eating habits cause the given differences, rather than the level of physical activity, regardless of sex. [ABSTRACT FROM AUTHOR]

Introduction: among the groups more affected by the COVID-19 pandemic were patients undergoing chronic hemodialysis (HD) treatment due to their comorbidities, advanced age, impaired innate and adaptive immune function, and increased nutritional risk due to their underlying inflammatory state. All of these factors contribute to a higher risk of severe complications and worse outcomes compared to the general population when infected with SARS-CoV-2. Objective: the objective of this study was to describe the nutritional characteristics of and their potential association with the prognosis of COVID-19 in patients undergoing chronic HD treatment. Method: a descriptive, retrospective, observational design. All cases of COVID-19 in patients undergoing chronic treatment at the Hemodialysis Unit of Hospital de Manises, Valencia, Spain, from the start of the pandemic to before vaccination were included. Results: for that, 189 patients were studied, who received chronic HD treatment in the hospital unit, 22 patients were diagnosed with COVID-19 (12 %) in that period. The mean age was 71 years, 10 were women, the Charlson index was 6.59 points, diabetes mellitus 10, vintage HD 51.6 months, 2 patients had previously received a currently non-functioning kidney transplant, 16 had arteriovenous fistula as vascular access, and 6 had central vascular access. The mean dialysis session time was 220.14 minutes and the initial value of the single dose of the Kt/V pool was 1.7. Sixteen patients had body composition measurement, a strong association (p < 0.05) was identified between mortality and BMI, as well as mortality and FTI. Furthermore, the differences between deceased and surviving groups in the serum levels of various variables related to nutritional status were analyzed, finding significant differences with p < 0.05 in the value of triglycerides and ferritin. Conclusions: higher body mass index and higher body fat content, along with lower baseline levels of triglycerides and ferritin, were significantly associated with higher COVID-19 mortality in patients on chronic hemodialysis. These findings suggest that the initial nutritional status of these patients can significantly influence the prognosis of SARS-CoV-2 infection. [ABSTRACT FROM AUTHOR]

Introduction: clinical practice guidelines recommend considering pharmacological treatment of obesity only as a complement to lifestyle modification. Drugs alone are usually ineffective in the long term after discontinuation, so pharmacological weight loss strategies should always be accompanied by lifestyle modifications. Objective: to analyze the changes in weight, body mass index and body composition by means of electrical bioimpedance after a 32-week treatment with liraglutide in patients with obesity, associated or not with a food education program. Materials and methods: the study involved 68 patients who were randomly divided into 2 groups. One group received treatment with liraglutide 3.0 mg/day along with individual dietary education, and the other group was treated with liraglutide 3.0 mg/day and standard medical follow-up for 32 weeks. The data collected were weight (kg), height (m) (Seca® brand), body mass index (kg/m2) and body composition using multifrequency bioimpedance (SECA 112® brand). The variables were analyzed at the beginning and at the end of the treatment. Results: after 32 weeks of treatment, both study groups lost weight significantly. The group treated with liraglutide and individual dietary education had a reduction of 8.77 kg (9.08 %) (p < 0.001) and the group treated with liraglutide without education had a reduction of 3.55 kg (3.45 %) (p < 0.001). The BMI of the participants treated with liraglutide and education decreased by -4,04 kg/m2 (10.35 %) (p < 0.001) and in the group without education it decreased by -3.22 kg/m2 (8.30 %) (p = 0.003). In the educated group, fat mass decreased by -7.65 kg (15.89 %) (p < 0.001), although skeletal muscle mass also decreased by -1.62 kg (6.8 %) (p < 0.001). In those treated with liraglutide without education, a reduction in fat mass and skeletal muscle mass was also observed -- fat mass by -4.72 kg (9.43 %) (p < 0.001) and skeletal muscle mass by -0.17 kg (0.70 %) (p < 0.001). Differences were also observed between groups, observing a greater reduction in weight, BMI, fat mass and skeletal muscle mass in the group with liraglutide and education compared to the group without education, although these differences were not statistically significant. Conclusions: dietary education associated with liraglutide treatment may contribute to increasing weight and fat mass losses. However, it was also associated with an unwanted loss of skeletal muscle mass, probably related to the greater intensity of weight loss, which will have to be reversed in future therapeutic approaches. Habit modification through multidisciplinary treatment, including nutritional education, combined strength and resistance exercise, and cognitive-behavioral therapy, could be an effective way to treat obesity and maintain weight, body composition, and adherence to a lifestyle.

Introduction: The physiological changes that manifest in children and adolescents during their growth and development have a significant impact on their adult life. Objective: To evaluate the evolution of physiological changes in 2 samples of children and adolescents using bioelectrical impedance vector analysis. Methods: Two samples of infant-juvenile populations of both sexes were used, a Cuban sample of 1067 individuals and an Italian sample of 1823, from two databases. The nomogram and the linear fit to each sample were performed, based on a mathematical model of the form characterize the trajectory of the data of each sample. Results: In the Cuban sample, the mean impedance vectors overlap from the 2 age group to the 12 age group. From the age of 13 years, the vectors of both sexes separate. In the Italian sample, these vectors overlap from the age group 2 years to the age group 13 years. From the 14 to 15 age group, the vectors of both sexes are separate. Both samples followed a straight line, decreasing with increasing age. Conclusions: The changes that occur in the bioelectrical vectors from childhood to adolescence are due to modifications in the stages that lead from childhood to puberty from the physiological point of view.

The intensive care units (ICU) and acute care units have been the containers for the advance of the COVID-19 pandemic. However, prolonged stay in this unit can impact patients' body composition (WC) and ability to exercise. This research aimed to determine if there is a relationship between body composition (BC) and the 6-minute walk test (6mWT). 17 people were recruited (8 women and 9 men). The following measurements were taken: 6mWT, its distance traveled (6mWTDT) and its speed (6mWTS) were considered. The WC variables measured were body mass index (BMI), fat mass (FM), fat-free mass (FFM), and lean mass (LM). 6mWTDT only showed a significant relationship with body LM (BLM). On the other hand, 6mWTS had a significant relationship with BLM. In addition to this, the FFM of the right lower limb and the FFM of the left lower limb showed a relationship with 6mWTS (r=0.422; p=0.041 and r=0.417; p=0.025, respectively). Also, the LM of the right lower limb and the LM of the left lower limb were significantly related to the 6mWTS (r=0.422; p=0.030 and r=0.420; p=0.042). In conclusion, there is a relationship between body composition and 6mWTS. This would allow us to quickly approach the level of functionality with which a patient enters a rehabilitation program.

The aim of this study was to determine the sensitivity of different methods of partialization, in terms of different body component indices in relation to indicators of strength and explosiveness. The research involved 187 subjects who were divided into two groups based on sex. This research consisted of measuring body composition characteristics by multichannel bioimpedance analysis (BIA) InBody 720, as well as contractile characteristics of different muscle groups with tenziometric Dinamometry method. Based on the results of the factor analysis we found that regardless of the sex the most sensitive variable for partialization of absolute body isometric strength variable (ABiS) is partialization by allometric scaling (0.964 for females and 0.947 for males explained factor variance). However, in the case of absolute body isometric explosiveness (ABiE), the results of this study have demonstrated that partialization relative to skeletal muscle mass according to the body longitudinality – skeletal muscle mass index (SMMI) is the methodological choice disregarding the sex (0.982 for females and 0.980 for males explained factor variance). The results of the study have shown that for the purpose of scaling the maximal strength relative to body composition, the allometric method can be considered as a choice, while for the partialization of maximal isometric explosiveness skeletal muscle mass index is the best choice insensitive of the sex.

Tang Soo Do is a versatile martial art that stands out for the use of the hip for its technical gestures. Karate is one of the most attractive martial arts around the world. Both karate and Tang Soo Do share a firm style in their techniques and combat. However, some of the forms in Tang Soo Do possess a gentle style similar to Kung Fu and Tai Chi. Therefore, it is interesting to describe and compare the physical abilities and body composition of recreational Tang Soo Do and karate practitioners. A search was carried out in Medline® and Web of Science® during January 2021. Following the search 10 studies were chosen, organizing their data according to body composition, muscular strength, muscular resistance, flexibility and VO2max. Two studies were found on recreational Tang Soo Do practitioners and eight on karate worldwide, hence, there are not enough studies to adequately describe and compare physical abilities and body composition among recreational practitioners; However, the results found, indicate that it is important to conduct further research to measures these variables, in order to consider Tang Soo Do as an important option for the physical and mental well-being of its practitioners. Future research can evaluate these data can be evaluated in different age groups, location, training time or types of competitions according to forms, combat or mixed. In addition, comparative studies can be carried out on Tang Soo Do practitioners that allow this martial art to become an important option for practice in schools and universities, as well as a lifestyle for its practitioners.

La diabetes es una enfermedad endocrina. La absorciometría de rayos X de energía dual (DXA) proporciona una vista detallada de la composición corporal para descubrir qué diferencia a las personas con diabetes de aquellas con otras enfermedades. Escaneamos a 371 pacientes con DXA para analizar sus parámetros de composición corporal. Se incluyeron 371 pacientes (178 mujeres/193 hombres), con diferentes enfermedades, con un Índice de Masa Corporal (IMC) medio ± DE de 25,32 ± 8,3 kg/m². Se evaluó la composición corporal de 371 pacientes. Se analizaron la densidad mineral ósea (DMO), el peso graso, el peso magro, la relación cintura-cadera, el índice de masa magra (LMI), el índice de masa grasa (FMI), y la relación entre el porcentaje de grasa y el IMC. De los 371 pacientes 156 eran diabéticos y 215 no diabéticos. Los pacientes no diabéticos también incluyeron 5 con obesidad, 9 con hígado graso, 39 con hipertensión, 22 con hiperlipidemia, 18 con enfermedad cardiovascular, 11 con enfermedad torácica y pulmonar, 4 con enfermedad crónica, 14 con enfermedad cerebral y 93 pacientes con otras enfermedades. Entre los 156 pacientes diabéticos, 129 tenían un IVA > 100 cm² y 27 tenían un IVA ≤100 cm². El peso magro (PV) de los hombres diabéticos fue significativamente mayor que el de las mujeres diabéticas. El peso graso (FW) de las mujeres diabéticas fue significativamente mayor que el de los hombres diabéticos. El índice cintura-cadera (ICC) fue de 1,37 ± 0,25 en hombres diabéticos y de 1,18 ± 0,21 en mujeres diabéticas. Entre los 215 pacientes no diabéticos, los pacientes obesos y con hígado graso, cuyo peso (WT) (obesidad: 83,87 ± 8,34 kg hígado graso: 85,64 ± 28,60 kg), FW (obesidad: 28,56 ± 4,18 kg hígado graso: 28,61 ± 10,79 kg), PV (obesidad: 52,62 ± 9,64 kg, hígado graso: 54,29 ± 17,58 kg), IMC (obesidad: 28,76 ± 1,88 kg/m², hígado graso: 29,10 ± 5,95 kg/m² ), fue mucho mayor que otros pacientes. Los pacientes diabéticos tenían menos masa grasa que los pacientes no diabéticos; la diferencia fue de alrededor de 2 kg. La DMO no difiere mucho. Los pacientes no diabéticos con obesidad debido al hígado graso y enfermedades cardiovasculares tenían mayor masa grasa e IMC que los pacientes con otras enfermedades. La composición corporal puede proporcionar información precisa sobre la composición de diferentes áreas del cuerpo, pero se requieren exámenes más profundos para determinar el perfil endocrino del cuerpo.

Introduction: body composition (BC) analysis is an essential element in clinical nutritional practice. Bioelectrical impedance is one of the most widely used techniques for estimating BC. Several approaches have been proposed to reduce the margin of error it presents, ensuring its application in all populations. One of them is the use of impedance vectors, using tolerance ellipses. Objective: to compare the sample vectors with the Italian population and to determine specifi c tolerance ellipses for the Colombian university population. Materials and Methods: observational cross-sectional study in 608 university students. Participation was at convenience and voluntary, between February 2022 and March 2023. BIVA 2002 software was used to calculate the tolerance ellipses and BIVA confi dence to compare the vectors of the ellipses with the Italian population using Hotelling's T2 test, which was considered as signifi cant at p < 0.05. Results: R/H and Xc/H measurements were higher in females (420.75 ± 56.012 O/m vs 308.7508 ± 41.81 O/m) and (46.15 ± 5.79 O/m vs 39.44 ± 5.01 O/m), respectively. The impedance vectors were positioned over the upper quadrants of the RXc plot, evidencing signifi cant differences in the distribution of the composition vectors between samples. Conclusions: the vectors of the Colombian university students were different from the reference population, so it was necessary to determine the specifi c ellipses. [ABSTRACT FROM AUTHOR]

Objective: The detection and classification of sarcopenia involves the analysis of many variables (50 to 60), which increases the time and costs required to diagnose and manage this condition. The objective of the study was to develop a synthetic statistical index to diagnose and classify sarcopenia in physically active women over 60 years old. Methodology: We conducted a cross-sectional study on 100 physically active women (64.88 ±4.4 years) on whom body composition measurements, muscle strength, and gait tests were performed. One thousand random selections of both training and test sets (80% and 20%, respectively) were made, logistic regression was fitted, and the regularization procedure (Elastic net regression) was performed. Results: the skeletal appendicular mass index (kg/m2), muscle mass (kg/m2) and SAMI (kg/m2) are highly correlated (0.93) and slow gait speed (m/sec) were the variables that contributed the most to the diagnosis of sarcopenia with a visibly high correlation, (94%). Conclusion: appendicular lean mass, gait speed, and explosive strength sufficiently describe the state of muscle and functional deterioration (sarcopenia) in physically active older women. Also, the precise identification and classification of this condition facilitates comprehensive multidisciplinary intervention, increasing the positive impact of health promotion and disease prevention programs.
