Triceps Skinfold Thickness (triceps + skinfold_thickness)
Selected AbstractsTwo new potent and convenient predictors of mortality in older nursing home residents in JapanGERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 2 2004Orie Tajima Background: Malnourishment is closely connected with poor health outcomes in frail elderly. However, the relative importance of specific nutritional predictors of mortality remains unclear in the Japanese population. We investigated the potent nutritional factors associated with mortality from nutritional assessments of three parameters in Japanese frail elderly. Methods: Ninety residents in a nursing home in Japan, aged 65 and over (18 men, 72 women; mean age 82.2 ± 8.0 years) were enrolled in a 38-month follow-up study. The eligibility condition for analysis was having lived at the nursing home for more than 30 days, so three participants were excluded. Three nutritional parameters, which included: anthropometric measurements (body mass index, mid-arm circumference, triceps skinfold thickness and calf circumference); serum markers (albumin, total protein, prealbumin, retinol binding protein and total cholesterol); and food intake, were assessed. After categorizing each putative factor according to tertile distribution, risk of mortality was analyzed using Cox proportional hazard models. Results: At the end of the 38-month follow-up period, 29 participants had died. After adjustment for gender, age, clinical status, and functional status, three indicators (i.e. mid-arm circumference, triceps skinfold thickness and lipid intake) showed a significant relationship with mortality. When all of the putative factors were included in a stepwise procedure, mid-arm circumference and lipid intake were significantly associated with adjusted mortality. Conclusion: Among institutionalized Japanese frail elderly, lower levels of mid-arm circumference and lipid intake could potently predict an increased risk of mortality. These two indicators may be useful for many kinds of assessments and intervention for the improvement of health conditions in Japanese frail elderly. [source] Dialysis adequacy and nutritional status of hemodialysis patientsHEMODIALYSIS INTERNATIONAL, Issue 1 2008Fernanda TEIXEIRA NUNES Abstract To characterize the nutritional status of renal failure patients and its relationship with hemodialysis adequacy measured by Kt/V, a study was carried out with a population of 44 adult patients with renal failure and mean age 51±15 years. Anthropometric data, such as dry weight, height, arm circumference, triceps skinfold thickness, mid-arm muscle circumference, and body mass index were assessed, and biochemical tests were conducted for urea, potassium, creatinine, serum albumin, and phosphorus levels, in addition to hemogram and quarterly urea reduction rate average (Kt/V). In order to evaluate calorie intake, a dietary questionnaire on habitual daily food ingestion was administered, taking into consideration the hemodialysis date. The patients were divided into 2 separate groups for the statistical analysis, with 50% of the patients in each group: A (Kt/V<1.2) and B (Kt/V>1.2). The data were tabulated as mean and standard deviation, with differences tested by Student's t test. The correlations between variables were established by the coefficient p of Pearson. Most of the patients (43%) were considered eutrophic, based on the BMI, and presented inadequate calorie intake, corresponding to 88.5±24% (30.8 kcal/kg actual weight) of the total energy required and adequate protein intake, reaching 109.9±40% of the recommended daily allowance (1.24 g/kg of actual weight). There was a correlation of Kt/V with anthropometric parameters such as body mass index, arm circumference, and mid-arm muscle circumference. The biochemical parameters related to dialysis adequacy were albumin, ferritin, and urea (predialysis). Well-dialyzed patients presented better levels of serum albumin. There was an influence of gender and age on correlations of the analyzed variables. Female and younger patients presented better dialysis adequacy. The dialysis adequacy was related to the nutritional status and influenced by the protein intake and body composition. Gender and age had an important influence in the dialysis adequacy, as men presented lower dialysis adequacy and younger adults presented better dialysis adequacy. Further research is necessary to understand better how to facilitate effective and efficient techniques for the nutritional status assessment of hemodialysis patients. [source] Percutaneous endoscopic gastrostomy feeding in haemodialysis out-patientsJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 5 2000H. A. Sayce Introduction Malnutrition is highly prevalent in haemodialysis (HD) patients and plays a major role in influencing outcome. Although use of home enteral feeding is expanding rapidly in the UK, it is a method of nutritional support which remains under-utilized in HD out-patients. We report our experience and outcomes in a series of eight cases. Methods Home gastrostomy feeding was initiated in eight malnourished HD out-patients, administered either continuously overnight or as daily bolus feeds. Nutritional parameters were monitored weekly by the renal dietitian and included dry weight, upper-arm anthropometry and serum albumin. The number and duration of hospitalizations during the period of feeding were recorded. Results After 3 months of feeding, median dry weight increased from 43.0 to 48.3 kg (P = 0.012), mid-upper arm circumference increased from 20.2 to 24.8 cm (P = 0.018), triceps skinfold thickness increased from 7.3 to 11.3 mm (P = 0.046), mid-upper arm muscle circumference increased from 17.7 to 19.8 cm (P = 0.027) and serum albumin increased from 29.5 to 36.5 g L,1 (P = 0.011). Few complications were encountered and hospital admission rates were low. Conclusion Home gastrostomy feeding, with appropriate monitoring and support, is an effective method of improving and maintaining nutritional status in this vulnerable group. [source] Body composition and respiratory function in healthy non-obese childrenPEDIATRICS INTERNATIONAL, Issue 5 2007FRANCISCO J. GONZALEZ-BARCALA Abstract Background: The purpose of the present paper was to evaluate the role that body composition plays in lung function, among healthy children and adolescents. Methods: Cross-sectional study was undertaken using sex- and age-stratified sampling among healthy children and adolescents aged 6,18 years. Spirometry was performed on every child who fulfilled inclusion criteria. Fat mass (FM) and fat-free mass (FFM) were calculated from triceps skinfold thickness and arm circumference. Multiple logistic regression was used to obtain adjusted prevalence odds ratios (OR) and 95% confidence intervals (95%CI) between low pulmonary function (PF) of schoolchildren and body composition expressed in FM and FFM. Calculations of OR imply that the outcome is dichotomous (low PF/normal PF), therefore those children who had parameters of pulmonary function below the 25th percentile were classed as cases and the rest of the subjects were considered as controls. Results: A total of 2408 children were included; 1270 (53%) of them were male and 1138 (47%), female. Among boys the increase of FFM was associated with an increase of forced expiratory volume in 1 s (FEV1). Among girls the increase of FFM was associated with an increase of FEV1, forced vital capacity, and peak expiratory flow. The increase in FM was associated with a decrease of spirometric parameters in both genders, with a stronger effect among boys. Conclusions: The present study confirms the negative effect of body fat on the PF of children and adolescents, even though obese subjects were excluded. The effect is different between boys and girls. [source] Evaluation of iron deficiency as a nutritional adaptation to infectious disease: An evolutionary medicine perspectiveAMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 2 2009Katherine Wander An evolutionary perspective suggests that iron deficiency may have opposing effects on infectious disease risk, decreasing susceptibility by restricting iron availability to pathogens, and increasing susceptibility by compromising cellular immunocompetence. In some environments, the trade-off between these effects may result in optimal iron intake that is inadequate to fully meet body iron needs. Thus, it has been suggested that moderate iron deficiency may protect against acute infection, and may represent a nutritional adaptation to endemic infectious disease stress. To test this assertion, we examined the association between infection, reflected by C-reactive protein, a biomarker of inflammation, and iron status, reflected by transferrin receptor (TfR) and zinc protoporphyrin to heme ratio (ZPP:H), among school-age Kenyan children, and evaluated the hypothesis that moderate iron deficiency is associated with lower odds of infectious disease. TfR > 5.0 mg/l, with sensitivity and specificity for iron deficiency (ZPP:H > 80 ,mol/mol) of 0.807 and 0.815, was selected as the TfR definition of iron deficiency. Controlling for age and triceps skinfold thickness (TSF), the odds ratio (OR) for acute viral or bacterial infection associated with iron deficiency (compared to normal/replete) was 0.50 (P = 0.11). Controlling for age and TSF, the OR for infection associated with an unequivocally iron replete state (compared to all others) was 2.9 (P = 0.01). We conclude that iron deficiency may protect against acute infection in children. Am. J. Hum. Biol, 2009. © 2008 Wiley-Liss, Inc. [source] Prevalence of overweight among adolescent females in the United Arab EmiratesAMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 6 2003Huda M. Al-Hourani The purpose of the study was to investigate the prevalence of overweight in adolescent females in the United Arab Emirates (UAE). A total of 898 females, ages 11,18 years, were recruited from five of the seven Emirates with the highest resident Emirati population. Height, weight, triceps skinfold thickness (TSF), and mid-upper-arm circumference were measured in each subject. Reference data from the National Health and Nutrition Examination Surveys (NHANES) were used for comparison. At risk for overweight or overweight were defined as a body mass index (BMI, kg/m2) ,85,95th percentile and ,95th percentile, respectively. Mean values for BMI and TSF at all ages were higher than the 50th percentile (median) of the NHANES reference data. Using the BMI classification, 14% and 9% of all subjects were classified as at risk for overweight or overweight, respectively. The proportion of subjects at risk for overweight ranged between 7,19% and the prevalence of overweight ranged between 6,15%. The proportion of subjects with a BMI ,85 percentile ranged from 15% at age 17 years to 33% at age 11 years. Furthermore, 27% and 28% of subjects ages 11 and 12 years, respectively, were above the TSF 90th percentile. These two age groups also showed a high prevalence of overweight using the BMI classification. In conclusion, the findings from our study suggest that a high proportion of adolescent females in the UAE are overweight or at risk for overweight. The consequences of this are a serious concern for public health and need to be addressed. Am. J. Hum. Biol. 15:758,764, 2003. © 2003 Wiley-Liss, Inc. [source] The relationship between sleep duration and obesity in Turkish children and adolescentsACTA PAEDIATRICA, Issue 4 2009A Ozturk Abstract Aim: To determine the relationship between sleep duration and obesity in Turkish children and adolescents. Methods: This study was conducted in Turkey with 5358 children aged 6 to 17 years. Height, weight, waist circumference (WC), mid-upper arm circumference (MUAC), triceps skinfold thickness were measured. Body mass index (BMI), arm fat area were calculated. Self-reported sleep duration by parents were obtained. Results: As sleep duration increased, BMI, which was significantly higher in girls sleeping ,8 h, decreased (p < 0.05). WC, MUAC, BMI were significantly higher in boys sleeping ,8 h versus males sleeping ,10 h. Boys sleeping ,10 h in 6.0,17.0-years had significantly higher risk of overweight/obesity. In 6.0 to 17.0 years, the risk of overweight/obesity in boys sleeping 9,10 h, 8,9 h and ,8 h were 1.86-, 1.74- and 2.06-times higher respectively, versus children sleeping ,10 h (p < 0.05). Conclusion: Sleep duration may be an important factor for obesity and providing ,10 h of sleep is recommended as a prevention strategy for obesity. [source] The changes in serum leptin, body fat mass and insulin resistance after renal transplantationCLINICAL TRANSPLANTATION, Issue 1 2003S Mehmet Kayacan Abstract:,Background:, In this prospective-controlled study, we aimed to investigate the effect of changes in insulin resistance and anthropometrical parameters on serum leptin levels (SLL) after renal transplantation (Tx). Patients and methods:, Thirty-four patients (M/F: 19/15, mean age: 29 ± 9 yr) and 30 age and sex-matched healthy controls (C) were included. Body weight, subscapular, suprailiac, periumbilical, biceps and triceps skinfold thicknesses, neck, wrist, hip and waist circumferences, as well as body mass index and body fat mass were measured as anthropometrical parameters. In order to measure the serum glucose, insulin and SLL, blood samples were obtained before and 1 wk, 1 and 6 months after Tx. Homeostasis Model Assessment (HOMA) values were calculated as an index of insulin resistance. Results:, Serum leptin levels (SLL) of the patients at pre-Tx were significantly higher than C (21.5 ± 3.5 vs. 7.8 ± 0.9 ng/mL, p = 0.002) and decreased at first week after Tx (from 21.5 ± 3.5 to 8.4 ± 1.5 ng/mL, p < 0.001). Thereafter, it gradually increased to 12.8 ± 2.1 ng/mL in the first month and to 14.4 ± 2.1 ng/mL in the sixth month after Tx. Serum leptin levels at sixth month were significantly higher than C (p = 0.005). Serum insulin and HOMA values changed similar to SLL after Tx. Correlations between SLL and HOMA persisted during the study period [pre-Tx (r: 0.40) and at first (r: 0.38) and sixth (r: 0.47) months]. In linear regression analysis, HOMA and fat mass were found as independent variables for predicting SLL at the sixth month after Tx. Conclusion:, Serum leptin levels dramatically decreased immediately after Tx and significantly correlated with serum insulin levels and HOMA during the entire study. Increase in SLL at sixth months was probably because of increase in fat mass, insulin resistance and steroid use in renal transplant recipients. [source] | ||||||||||
