ABSTRACT
【Objective】 To investigate the correlation between body composition and thyroid function indicators in type 2 diabetic patients with euthyroidism of different genders. 【Methods】 Type 2 diabetic patients with euthyroidism who were hospitalized in the Endocrinology Department of The Second Affiliated Hospital of Xi’an Jiaotong University from February 2016 to September 2018 were enrolled in this study. Bioelectric impedance analysis was used to measure body composition, and the thyroid function indicators (FT3, FT4, and TSH) were tested. The male and female subjects were matched according to the ratio of 2:1 using the propensity score matching method, and the correlation between body composition and thyroid function indicators was studied in different genders by correlation analysis. 【Results】 The basal metabolic rate, trunk fat mass, fat-free mass, fat-free mass index, bone mass, water mass, total body muscle mass, skeletal muscle mass, and skeletal muscle index were positively correlated with FT3 in male patients (P<0.05). The percentage of body fat mass and fat mass index were positively correlated with FT3 and TSH (P<0.05), and the percentages of lean mass, water mass, and total body muscle mass were negatively correlated with FT3 and TSH (P<0.05), and the basal metabolic rate was negatively correlated with FT4 (P<0.05) in female. 【Conclusion】 In euthyroid type 2 diabetic patients, the correlation between body composition and thyroid function indicators are different between males and females. In males, only FT3 is positively correlated with basal metabolic rate, trunk fat mass, and fat free-related composition; while in females, both FT3 and TSH are positively correlated with fat-related composition, but negatively correlated with fat-free-related composition.
ABSTRACT
RESUMEN El objetivo de este estudio fue determinar la relación entre consumo de alimentos ultraprocesados y los indicadores del estado de nutricional de una muestra de población económicamente activa en México. Se realizó un estudio transversal en individuos de ambos sexos (18 a 60 años, n=150). Para la obtención de datos antropométricos de la población y de composición corporal, se utilizó un equipo de bioimpedancia. Además, se aplicó un cuestionario de frecuencia de consumo de alimentos ultraprocesados (previamente validada) para la evaluación dietética. Los resultados de los indicadores de estado nutricional demostraron que el 80% de la población estudiada presentó obesidad y sobrepeso; el 88,7% tuvo un % de grasa alto; y el 75,3% presentó riesgo metabólico alto. Con respecto a la evaluación dietética, el grupo de alimentos de ultraprocesados con alto contenido de azúcares simples fue el de mayor consumo (47%, 10,4 veces por semana). Los resultados del análisis de correlación de Pearson, indicaron que existe una correlación negativa significativa entre la edad y el consumo en cuatro de cinco grupos de alimentos ultraprocesados. Finalmente, se encontró que la muestra presenta riesgos de salud importantes que pueden afectar su calidad de vida y productividad. Se deben implementar estrategias a corto plazo de mejora de hábitos de alimentación y estilo de vida saludables en este sector de la población tan importante.
ABSTRACT This work aimed to correlate ultra-processed product consumption and nutritional status in a sample of the Mexican labor force population. A cross-sectional study assessed subjects from both genders (18 to 60 years, n=150). Bioimpedance equipment was used to obtain anthropometric measurements and body composition parameters. Moreover, a previously validated frequency questionnaire of ultra-processed foods was used to obtain dietetic data. Results from the nutritional status evaluation indicated that 80% of the sample was obese or overweight; 88.7% had high total fat mass percentage, and 75.3% had high metabolic risk. Regarding the dietetic evaluation, ultra-processed products with high sugar content were the most consumed (47%, up to10.4 times per week). Furthermore, the Pearson correlation analysis results showed a significant negative correlation between age and consumption in four of the five ultra-processed product groups evaluated. Therefore, there is a need to implement internal strategies to diminish the consumption of ultra-processed products and improve healthy food choices and physical activity of the sample to avoid quality of life deterioration and reduce economic losses in this sector.
ABSTRACT
Owing to the combined effect of tumor burden and cancer therapy, pediatric patients with tumor with a high incidence of malnutrition.Traditional nutritional indicators(such as weight, body mass index, and albumin, etc)fail to distinguish between adipose tissue and muscle tissue, which has limitations in evaluating the nutritional status of children with tumor.With the rapid development of body composition analysis techniques, the assessment of body composition can not only obtain the objective quality of each component of body mass but also enable longitudinal monitoring of nutritional status, therefore it plays a critical role in the assessment of nutritional status and the development of individualized nutritional support protocols in children with tumor.This review summarizes the application of body composition analysis for nutritional assessment in childhood cancer.
ABSTRACT
The maternal components are constantly changing with gestational weight gains during pregnancy. Body composition analysis is a method for evaluating the maternal body composition accurately during pregnancy, models of which consist of fat mass, extracellular water, intracellular water, inorganic salts and protein basically. Among various methods to execute body composition analysis, bioelectrical impedance analysis is an important method for pregnant women. Many studies have reported about clinical applications based on correlations between maternal individual components and gestational diseases. This article reviews the researches on clinical applications of body composition analysis to pregnant women.
ABSTRACT
Heart failure is the final stage of heart disease caused by various causes,it has a high rate of morbidity,re-hospitalization and mortality,and therefore,it becomes a particularly serious and common clinical syndrome.Research indicates that body composition analysis can provide more valuable clinical data for illness such as heart failure and chronic obstructive pulmonary disease.
ABSTRACT
Objective At present no deep investigation has been done on the relationship between handgrip strength and appendicular lean mass (ALM) in patients with chronic obstructive pulmonary disease (COPD). The study aimed to explore the present situation of handgrip strength in patients with stable COPD and relationship between handgrip strength and ALM.Methods A total of 93 patients with stable COPD who hospitalized in our department from August 2016 to July 2017 were selected for the study. All the patients underwent handgrip strength test, body composition analysis, as well as the analysis of the relationship between handgrip strength and ALM.Results Multivariate linear regression analysis showed age(X1), education(X2), smoking(X3), course of disease(X4) and lower limb lean mass(X5) could be taken as predictive factors for the variation degree of handgrip strength (R2=50.5%), and multiple linear regression equation was Y=9.959-4.315X1+1.397X2+2.679X3-1.526X4+1.538X5. The variation degree decreased to 48.1% when the course of disease was removed from the model, 28.3% when the limb lean mass was removed, 26.5% when two variables were removed. The correlation coefficients of ALM, upper limb, lower limb and torso lean mass (\[22.32±3.25\]kg, \[6.48±1.05\]kg, \[15.83±2.26\]kg, \[22.27±3.22\]kg) with handgrip strength (\[32.27±7.27\]kgf) were respectively 0.484, 0.436, 0.496 and 0.496 (P＜0.01).Conclusion The handgrip strength in patients with stable COPD is closely associated with ALM, and the course of disease and the lower limb lean mass greatly affect the handgrip strength. Clinical workers should pay extra attention to the relationship in order to give timely clinical intervention.
ABSTRACT
Objective:To evaluate the nutritional status before and after chemotherapy in patients with colon cancer by measuring energy metabolism and body composition.Methods:Fifty-one patients with colon cancer were included and were investigated using self-control method (before and after chemotherapy).Resting energy expenditure (REE) was determined by bed metabolic instrument,and body composition was measured by body composition analyzer.Results:For all patients,the REE on the 2nd day after chemotherapy was decreased significantly compared with that before chemotherapy (P ＜ 0.05).After chemotherapy,body fat percentage and body moisture percentage were increased significantly (P ＜ 0.05),and lean body mass percentage was decreased significantly (P ＜ 0.05).Conclusion:After chemotherapy,the REE and lean body mass percentage of the patients with colon cancer were decreased,and body fat percentage and body moisture percentage were increased.
ABSTRACT
Impedance plethysmography (IPG) came into existence in 1940 as a result of Jan Nyboer’s pioneering work in the noninvasive assessment of central and peripheral blood flow. The technique got an impetus after introduction first-time derivative of the impedance for accurate determination of stroke volume (SV) and various cardiac intervals. Later, this signal was employed by Parulkar et al for estimation of blood flow index (BFI) and differential pulse arrival time (DPAT) in various segments of the extremity, which were adequate to detect the aortic and peripheral arterial blocks and estimate collateral circulation and distal arterial runoff. The technique was widely used for measurement of respiration and body water. All these applications have resulted into use of bioimpedance for body composition analysis and continuous monitoring of cardiac output as US Food and Drug Adminstration (FDA) approved technologies, which are being used worldwide. Physiological variability has added more value to this technique as single data acquisition gives variability in heart rate and SV (or peripheral blood flow). Morphology index thus derived is very useful in screening patients suspected with coronary artery disease (CAD). All these milestones are briefly described in this paper.
ABSTRACT
Objective To explore the changes of appendicular skeletal muscle (ASM) in peritoneal dialysis (PD) patients, and to analyze the relationship between ASM changes and dietary intake.Methods One hundred and fourteen PD patients were enrolled in Department of Nephrology, Peking University Third Hospital using convenience sampling.At baseline, and 6 and 12 months after PD, bioelectrical impedance analysis was used to assess the body weight, total muscle mass, and ASM of these patients, and three-day food record was used to assess the dietary intake.Demographics and clinical data were also collected at baseline.Results Compared with baseline, the patients' ASM at 12 months after PD decreased significantly [(19.27 ± 5.59) kg vs.(25.65 ±6.09) kg, P =0.000], the dietary protein intake and energy intake decreased significantly [(0.85 ± 0.21) g/(kg · d) vs.(0.90 ± 0.27) g/(kg · d), P =0.038;(128.37 ± 26.67) kJ/(kg· d)vs.(137.27 ±29.23) kJ/(kg· d), P=0.001].The patients were divided into three groups based on ASM loss, the mean dietary protein intake of the top-loss 1/3 group was statistically lower than that of the bottom-loss 1/3 group [(0.82 ± 0.18) g/(kg · d) vs.(0.91 ± 0.20) g/(kg · d), P =0.021].Conclusions With the continuation of PD, ASM of patients may decrease, which is likely to be mainly related to deficiency in protein and energy intakes.Dietary management should be strengthened in PD patients to alleviate the loss of ASM.
ABSTRACT
Objective To observe the change of lipid metabolism during adaptive heart failure.Method The transverse aorta constriction mouse models established by minimal invasive surgery technique were evaluated for early small changes of body composition by EchoMRITM whole body composition analysis,and the different gene expression was analyzed by whole genome expression microarray.Results Three weeks after the surgery,the fat composition,in the mouse models were (0.49 ± 0.13) g,which was significantly lower than that in the sham surgery group [(0.81-±0.14) g] (P =0.002).The expression of the natriuretic peptide type A significantly increased over time (R2 =0.939,P =0.005).In addition,the levels of fatty acid desaturase,long-chain fatty acid elongase 5,and N-acylsphingosine amidohydrolase increased,and the levels of acyl-coenzyme A dehydrogenase,muscle glycogen phosphorylase,and pyruvate dehydrogenase kinase decreased,showing increased fat mobilization and decreased carbohydrate utilization.Conclusions Surgery for transverse aorta constriction can cause complex metablic changes in heart.The activated lipid mobilization maybe lead to the low body fat composition.
