    Insulin sensitivity (IS) is the ability of cells to react due to insulińs presence; when this ability is diminished, low insulin sensitivity or insulin resistance (IR) is considered. IR had been related to other metabolic disorders as metabolic syndrome (MS), obesity, dyslipidemia and diabetes. IS can be determined using direct or indirect methods. The indirect methods are less accurate and invasive than direct and they use glucose and insulin values from oral glucose tolerance test (OGTT). The accuracy is established by comparison using spearman rank correlation coefficient between direct and indirect method. This paper aims to propose a lipid-anthropometric index which offers acceptable correlation to insulin sensitivity index for different populations (DB1=MS subjects, DB2=sedentary without MS subjects and DB3=marathoners subjects) without to use OGTT glucose and insulin values. The proposed method is parametrically optimized through a random cross-validation, using the spearman rank correlation as comparator with CAUMO method. CAUMO is an indirect method designed from a simplification of the minimal model intravenous glucose tolerance test direct method (MINMOD-IGTT) and with acceptable correlation (0.89). The results show that the proposed optimized method got a better correlation with CAUMO in all populations compared to non-optimized. On the other hand, it was observed that the optimized method has better correlation with CAUMO in DB2 and DB3 groups than HOMA-IR method, which is the most widely used for diagnosing insulin resistance. The optimized propose method could detect incipient insulin resistance, when classify as insulin resistant subjects that present impaired postprandial insulin and glucose values.

    Cephalic index (CI), the ratio of head breadth to head length, is widely used to categorise human populations. The aim of this study was to access the impact of anthropometric measurements on the CI of male Japanese university students. This study included 1,215 male university students from Tokyo and Kyoto, selected using convenient sampling. Multiple regression analysis was used to determine the effect of anthropometric measurements on CI. The variance inflation factor (VIF) showed no evidence of a multicollinearity problem among independent variables. The coefficients of the regression line demonstrated a significant positive relationship between CI and minimum frontal breadth (p regression analysis showed a greater likelihood for minimum frontal breadth (p regression analysis revealed bizygomatic breadth, head circumference, minimum frontal breadth, head height and morphological facial height to be the best predictor craniofacial measurements with respect to CI. The results suggest that most of the variables considered in this study appear to influence the CI of adult male Japanese students.

    Full Text Available http://dx.doi.org/10.5007/1980-0037.2009v11n2p217   A systematic review of original articles published between 1993 and 2007 and indexed in SciELO (Scientific Electronic Library Online was carried out to identify the anthropometric indicators used to assess abdominal obesity in different target subgroups, and to provide an overview of available evidence regarding the relationship between these anthropometric indicators and obesity-associated comorbidities. The articles were analyzed and the following data were collected:year of publication, sample size and age, anthropometric measure used to detect abdominal obesity, and main results of the study. The review comprised 47 articles which met all inclusion criteria, most of them published over the last 5 years. Waist-hip ratio and waist circumference were used as indicators of abdominal obesity in 34 and 11 of the articles reviewed, respectively. With respect to age range, the samples were heterogeneous in most of the studies (n=27 and ten included adolescents. Four studies were conducted on elderly subjects and three included children, but none exclusively involved adolescents as the target population. The sample size was larger than 500 in 26 studies. Despite disagreement in terms of the degree of correlation, the studies generally showed that the anthropometric indicators of abdominal obesity were correlated with hypertension, diabetes, dyslipidemias, and coronary heart risk. The results of this review suggest that abdominal obesity is associated with metabolic diseases. However, there is a lack of studies involving the adolescent population, suggesting the need for further research in this area.

    Programs focused on active aging do not always have actions to guide the elderly about healthy eating. Therefore, the concordance between the feeding habits and the morphological characteristics of this population group is little known. To correlate the anthropometric health indexes with the frequency of food consumption in physically active elderly (PAE). The sample consisted of 307 physically active Chilean elders of both sexes (8.4% males), with a mean age of 70.2 years. The studied variables corresponded to nutritional status, abdominal adiposity, cardiovascular risk and frequency of food consumption. A logistic regression model was applied, considering alpha active Chilean elderly who exhibit less healthy eating behavior.

    To investigate the association between various anthropometric indexes of obesity with arterial hypertension in elderly from Barbados (Bridgetown) and Cuba (Havana). Cross-sectional data were extracted from the Survey on Health, Aging and Well being in Latin America and the Caribbean (SABE). In Bridgetown and Havana, respectively, 1508 and 1905 subjects ( ≥ 60 years) were examined, and were selected by a controlled sampling design. The occurrence of hypertension was assessed by self-report. Multiple measurements of adiposity were used including body mass index (BMI ≥ 28 kg/m(2)), waist hip ratio (WHR = > 0.95 men; > 0.80 women), waist to height ratio (W/ht. = > 0.50) and waist circumference - WC(L) ( > 88 cm, women; > 102 cm, men) e WC(OK) ( > 90.3 cm, women; > 91.3 cm, men). Binary logistic regression analyses (Odds Ratio) were used to measure strengths of relationships. In the elderly of Bridgetown, the final design (adjusted for age, education, race, smoking, regular physical activity and diabetes) shows that, in men, WC(OK) and W/Ht were associated with hypertension, and in women, WCL and WCOK were the indexes associated. In the Cuban elderly, the final design shows that, with the exception of WHR, all indicators were associated with hypertension. WCOK and W/ht were the indexes most strongly associated with the outcome. The explanatory power of anthropometric indicators when determining the outcome differed between men and women, as well as between cultural groups living in relative proximity (Barbadians and Cubans).

    Full Text Available The worldwide prevalence of obesity mandates a widely accessible tool to categorize adiposity that can best predict associated health risks. The body adiposity index (BAI was designed as a single equation to predict body adiposity in pooled analysis of both genders. We compared body adiposity index (BAI, body mass index (BMI, and other anthropometric measures, including percent body fat (PBF, in their correlations with cardiometabolic risk factors. We also compared BAI with BMI to determine which index is a better predictor of PBF.The cohort consisted of 698 Mexican Americans. We calculated correlations of BAI, BMI, and other anthropometric measurements (PBF measured by dual energy X-ray absorptiometry, waist and hip circumference, height, weight with glucose homeostasis indices (including insulin sensitivity and insulin clearance from euglycemic clamp, lipid parameters, cardiovascular traits (including carotid intima-media thickness, and biomarkers (C-reactive protein, plasminogen activator inhibitor-1 and adiponectin. Correlations between each anthropometric measure and cardiometabolic trait were compared in both sex-pooled and sex-stratified groups.BMI was associated with all but two measured traits (carotid intima-media thickness and fasting glucose in men, while BAI lacked association with several variables. BAI did not outperform BMI in its associations with any cardiometabolic trait. BAI was correlated more strongly than BMI with PBF in sex-pooled analyses (r = 0.78 versus r = 0.51, but not in sex-stratified analyses (men, r = 0.63 versus r = 0.79; women, r = 0.69 versus r = 0.77. Additionally, PBF showed fewer correlations with cardiometabolic risk factors than BMI. Weight was more strongly correlated than hip with many of the cardiometabolic risk factors examined.BAI is inferior to the widely used BMI as a correlate of the cardiometabolic risk factors studied. Additionally, BMI's relationship with total adiposity

    The main purpose of this study was to develop Anthropometric, Growth and Maturity Index (AGaMI) in soccer and explore its differences to soccer player physical attributes, fitness, motivation and skills. A total 223 adolescent soccer athletes aged 12 to 18 years old were selected as respondent. AGaMI was develop based on anthropometric components (bicep, tricep, subscapular, suprailiac, calf circumference and muac) with growth and maturity component using tanner scale. Meanwhile, relative performance namely physical, fitness, motivation and skills attributes of soccer were measured as dependent variables. The Principal Component Analysis (PCA) and Analysis of Variance (ANOVA) are used to achieve the objective in this study. AGaMI had categorized players into three different groups namely; high (5 players), moderate (88 players) and low (91 players). PCA revealed a moderate to very strong dominant range of 0.69 to 0.90 of factor loading on AGaMI. Further analysis assigned AGaMI groups as treated as independent variables (IV) and physical, fitness, motivation and skills attributes were treated as dependent variables (DV). Finally, ANOVA showed that flexibility, leg power, age, weight, height, sitting height, short and long pass are the most significant parameters statistically differentiate by the groups of AGaMI (p<0.05). As a summary, body fat mass, growth and maturity are an essential component differentiating the output of the soccer players relative performance. In future, information of the AGaMI model are useful to the coach and players for identifying the suitable biological and physiological demand reflects more comprehensive means of youth soccer relative performance. This study further highlights the importance of assessing AGaMI when identifying soccer relative performance.

    A prospective study to attempt to relate the anthropometric parameters of height, weight, body mass index as well as age with the mammographic patterns obtained for the patients and obtain an anthropometric profile was carried out. The study was performed in 1.000 women who underwent a mammography in cranial-caudal and medial lateral oblique projection of both breasts, independently of whether they were screened or diagnosed. Prior to the performance of the mammography, weight and height were obtained, and this was also performed by the same technicians, and the patient were asked their bra size to deduce breast volume. With the weight, the body mass index of Quetelet was calculated (weight [kg]/height''2 (ml). After reading the mammography, the patient was assigned to one of the four mammographic patterns considered in the BIRADS (Breast Imaging Reporting and Data System) established by the ACR (American College of Radiology): type I (fat). type II (disperse fibroglandular densities), type III (fibroglandular densities distributed heterogeneously), type 4 (dense). The results were introduced into a computer database and the SPSS 8.0 statistical program was applied, using the statistical model of multivariant logistic regression. In women under 40 years, with normal weight, the dense breast pattern accounted for 67.8% and as the body mass index (BMI) increased, this pattern decreased to 25.1%. The fat pattern is 20% and as the BMI increases, this increased to 80%. In 40-60 year old women with normal weight, the dense pattern accounts for 44% and decreases to 20.9% in the grades II, III and IV obese. The fat pattern is 11.1% and increases to 53.7% in the grade II, III and IV obese. In women over 60 with normal, the dense pattern accounts for 19.3% and and decreases to 13% in the grade III obese. The fat pattern is 5.3% and increases to 20.2% in the grade iii of obesity. As age increases, the probability of presenting a mammographic pattern with a fat image in the

    Full Text Available Several complications during childhood is associated with nutritional status of infants at birth. Therefore, nutritional status of newborns must be evaluated properly after birth. Assessment of the nutritional status of neonates based on anthropometric and physical indices is simple and inexpensive without the need for advanced medical equipment. However, no previous studies have focused on the assessment methods of the nutritional status of infants via anthropometric and physical indices. This study aimed to review some of the key methods used to determine the nutritional status of neonates using anthropometric and physical indices. To date, most studies have focused on the diagnosis of fetal malnutrition (FM and growth monitoring. In order to diagnose FM, researchers have used growth charts and Ponderal index (PI based on anthropometric indices, as well as Clinical Assessment of Nutritional (CAN Score based on physical features. Moreover, in order to assess the growth status of infants, growth charts were used. According to the findings of this study, standard intrauterine growth curves and the PI are common measurement tools in the diagnosis of FM. Furthermore, CAN score is widely used in the evaluation of the nutritional status of neonates. Given the differences in the physical features of term and preterm infants, this index should be adjusted for preterm neonates. Longitudinal growth charts are one of the most prominent methods used for monitoring of the growth patterns of infants.

    Body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are used in screening and predicting obesity in adults. However, the best identifier of metabolic complications in children with obesity remains unclear. This study evaluated lipid profile distribution and investigated the best anthropometric parameter in association with lipid disorders in children with obesity. A total of 2243 school children aged 7-17 years were enrolled in Guangzhou, China, in 2014. The anthropometric indices and lipid profiles were measured. Dyslipidemia was defined according to the US Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents. The association between anthropometry (BMI, WC, and WHR) and lipid profile values was examined using chi-square analysis and discriminant function analysis. Information about demography, physical activity, and dietary intake was provided by the participant children and their parents. Children aged 10-14 and 15-17 years old generally had higher triglyceride values but lower median concentration of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol compared with children aged 7-9 years old (all P children aged 10-14 years old. The combination of age groups, BMI, WC and WHR achieved 65.1% accuracy in determining dyslipidemic disorders. BMI correctly identified 77% of the total dyslipidemic disorders in obese children, which was higher than that by WHR (70.8%) (Pchildren differed between younger and older age groups, and the tendency of these lipid levels remarkably fluctuated during 10 to 14 years old. BMI had better practical utility in identifying dyslipidemia among school-aged children with obesity compared with other anthropometric measures.

Measurements were taken from June 2008 to October 2009 at seven girl's high schools in Seoul, Korea. Participants were offered self-report questionnaire as a survey tool that included questions on anthropometric indices (height, weight, waist circumference, menarcheal age, menstrual pattern, frequency of menstruation per year.ResultsThe participants were categorized into three groups based on menarcheal age: early menarche group (younger than 2 standard deviations [SD], mid menarche group (within ±2 SD, late menarche group (older than 2 SD. The mean age of early menarche group was 9.9±0.2 years, mid menarche group 12.5±0.9 years, late menarche group 15.1±0.3 years (P < 0.001. Heights were recorded as 160.4±5.2 cm, 161.8±4.9 cm, 162.3±4.7 cm in early, mid, and late menarche group, respectively (P = 0.001. Body mass index (BMI and waist circumference significantly were lager in early menarche group than mid and late menarche ones (P < 0.001. The menarcheal age had a positive correlation with height and negative correlations with weight, BMI, waist circumference (P < 0.001. The prevalence of oligomenorrhea was more frequent in late menarche group than early and mid menarche group.ConclusionThe menarcheal age have positive relationship with height and inverse relationship with BMI and waist circumference in late adolescent girls in Seoul. Late menarcheal girls are disposed to have menstrual irregularity compared to early menarcheal girls.

    The present study examined 2-year changes in anthropometric variables and motor abilities in elite male youth soccer players to identify potential talent identification indexes. This was a cross-sequential study examining two different age groups at two time points. Height, weight, 40-m sprint speed, muscular power (5-step bounding), and change of direction (COD) ability (10 m×5 COD) were measured in 12- and 14-year-old soccer players and repeated after 2 years (at 14 and 16 years of age). Correlations and changes in ranking between the two measurements were determined. Both groups had small ranking changes in height (12-14-year-olds: r=0.80, 14-16-year-olds: r=0.89; ptalent identification index for youth soccer players. On the other hand, muscular power and COD ability is changeable during growth period suggests that these parameters is not useful for talent identification index.

    Body mass index (BMI) and endometriosis have been inversely associated. To address gaps in this research, we examined associations among body composition, endometriosis, and physical activity. Women from 14 clinical sites in the Salt Lake City, Utah and San Francisco, California areas and scheduled for laparoscopy/laparotomy were recruited during 2007-2009. Participants (N = 473) underwent standardized anthropometric assessments to estimate body composition before surgery. Using a cross-sectional design, odds of an endometriosis diagnosis (adjusted odds ratio [aOR]; 95% confidence interval [CI]) were calculated for anthropometric and body composition measures (weight in kg; height in cm; mid upper arm, waist, hip, and chest circumferences in cm; subscapular, suprailiac, and triceps skinfold thicknesses in mm; arm muscle and fat areas in cm 2 ; centripetal fat, chest-to-waist, chest-to-hip, waist-to-hip, and waist-to-height ratios; arm fat index; and BMI in kg/m 2 ). Physical activity (metabolic equivalent of task-minutes/week) and sedentariness (average minutes sitting on a weekday) were assessed using the International Physical Activity Questionnaire-Short Form. Measures were modeled continuously and in quartiles based on sample estimates. Adjusted models were controlled for age (years, continuous), site (Utah/California), smoking history (never, former, or current smoker), and income (below, within 180%, and above of the poverty line). Findings were standardized by dividing variables by their respective standard deviations. We used adjusted models to examine whether odds of an endometriosis diagnosis were moderated by physical activity or sedentariness. Inverse relationships were observed between endometriosis and standardized: weight (aOR = 0.71, 95% CI 0.57-0.88); subscapular skinfold thickness (aOR = 0.79, 95% CI 0.65-0.98); waist and hip circumferences (aOR = 0.79, 95% CI 0.64-0.98 and aOR = 0.76, 95% CI 0.61-0.94, respectively); total

    Chronic kidney disease (CKD) is associated with metabolic disorders, including insulin resistance (IR), mainly when associated with obesity and characterized by high abdominal adiposity (AbAd). Anthropometric measures are recommended for assessing AbAd in clinical settings, but their accuracies need to be evaluated. The aim of this study was to evaluate the precision of different anthropometric measures of AbAd in patients with CKD. We also sought to determine the AbAd association with high homeostasis model assessment index of insulin resistance (HOMA-IR) values and the cutoff point for AbAd index to predict high HOMA-IR values. A subset of clinically stable nondialyzed patients with CKD followed at a multidisciplinary outpatient clinic was enrolled in this cross-sectional study. The accuracy of the following anthropometric indices: waist circumference, waist-to-hip ratio, conicity index and waist-to-height ratio (WheiR) to assess AbAd, was evaluated using trunk fat, by dual x-ray absorptiometry (DXA), as a reference method. HOMA-IR was estimated to stratify patients in high and low HOMA-IR groups. The total area under the receiver-operating characteristic curves (AUC-ROC; sensitivity/specificity) was calculated: AbAd with high HOMA-IR values (95% confidence interval [CI]). We studied 134 patients (55% males; 54% overweight/obese, body mass index ≥ 25 kg/m(2), age 64.9 ± 12.5 y, estimated glomerular filtration rate 29.0 ± 12.7 mL/min). Among studied AbAd indices, WheiR was the only one to show correlation with DXA trunk fat after adjusting for confounders (P HOMA-IR values (r = 0.47; P HOMA-IR values was 0.55 (AUC-ROC = 0.69 ± 0.05; 95% CI, 0.60-0.77; sensitivity/specificity, 68.9/61.9).

    Low levels of serum 25-hydroxy vitamin D (25(OH)D) are common in type 2 diabetic patients and cause several complications particularly, in postmenopausal women due to their senile and physiological conditions. This study aimed to assess the effects of vitamin D-fortified low fat yogurt on glycemic status, anthropometric indexes, inflammation, and bone turnover in diabetic postmenopausal women. In a randomized, placebo-controlled, double-blind parallel-group clinical trial, 59 postmenopausal women with type 2 diabetes received fortified yogurt (FY; 2000 IU vitamin D in 100 g/day) or plain yogurt (PY) for 12 weeks. Glycemic markers, anthropometric indexes, inflammatory, and bone turnover markers were assessed at baseline and after 12 weeks. After intervention, in FY group (vs PY group), were observed: significant increase in serum 25(OH)D and decrease of PTH (stable values in PY); significant improvement in serum fasting insulin, HOMA-IR, HOMA-B, QUICKI, and no changes in serum fasting glucose and HbA1c (significant worsening of all indexes in PY); significant improvement in WC, WHR, FM, and no change in weight and BMI (stable values in PY); significant increase of omentin (stable in PY) and decrease of sNTX (significant increase in PY). Final values of glycemic markers (except HbA1c), omentin, and bone turnover markers significantly improved in FY group compared to PY group. Regarding final values of serum 25(OH)D in FY group, subjects were classified in insufficient and sufficient categories. Glycemic status improved more significantly in the insufficient rather than sufficient category; whereas the other parameters had more amelioration in the sufficient category. Daily consumption of 2000 IU vitamin D-fortified yogurt for 12 weeks improved glycemic markers (except HbA1c), anthropometric indexes, inflammation, and bone turnover markers in postmenopausal women with type 2 diabetes. www.irct.ir (IRCT2013110515294N1).

    Visceral adiposity index (VAI) is a new anthropometric indicator that makes it possible to define the risk of obesity-related cardiometabolic complications even before the diagnosis of metabolic syndrome. Evaluating the usefulness of VAI in order to differentiate metabolically unhealthy women (MU-PCOS) and defining the usefulness of this index in everyday practice. A prospective study was conducted among 43 women who met the Rotterdam criteria for diagnosing polycystic ovarian syndrome. Body composition was measured using bioelectrical impedance analysis. Statistical analysis was performed using STATISTICA v. 10 and relevant statistical tests. The adopted significance level was p = 0.05. Based on the study results, a significant positive correlation was found between the value of VAI and the concentration of insulin (r = 0.33; p index (r = 0.46; p correlation between VAI and the concentration of SHBG (r = -0.53; p HDL cholesterol (r = -0.88; p adiposity index makes it possible to introduce early prevention of metabolic disorders (including cardiometabolic disorders), as well as to evaluate the increase of hyperandrogenemia in women with polycystic ovary syndrome. The use of the cut-off point of VAI = 1.675 is a simple way to evaluate women with MU-PCOS.

    BMI (body mass index) is used to identify candidates for bariatric surgery, with a criterion of BMI ≥ 40. For lesser degrees of obesity, BMI 35-39.9, comorbidities are also considered. A Body Shape Index (ABSI) was derived to correct WC (waist circumference) for BMI and height. ABSI has been shown to be a linear predictor of long-term mortality across the range of BMI. Anthropometric risk indicator (ARI) combines the complementary contributions of BMI and ABSI and further improves mortality hazard prediction. We report for the first time ABSI and ARI for a bariatric surgical cohort at baseline and with 3-year follow-up. ABSI and BMI were calculated for 101 subjects from our bariatric surgery center database at baseline and after 3 years of follow-up. Raw values for BMI and ABSI were converted to Z scores and ARI values based on sex- and age-specific normals and risk associations from the National Health and Nutrition Examination Survey (NHANES) III sample of the US general population. Baseline scores for the anthropometric variables BMI and ABSI and the corresponding ARI were all higher than for the NHANES population sample. At 3-year post surgery, all three measures decreased significantly. While baseline BMI did not predict the change in mortality risk by ARI, baseline ABSI did (r = - 0.73), as did baseline ARI (r = - 0.94). Sleeve gastrectomy lowers ABSI and the associated mortality risk estimated from population studies after 3 years of follow-up. Considering our results, bariatric surgical candidates with BMI in the range of 35 to 39.9 with an increased ABSI-related mortality risk may have considerable survival benefit from bariatric surgery, even in the absence of qualifying comorbidities. 2814.

    The aim of the present study was to examine the effects of consumption of desserts with low glycemic index (GI) and low glycemic load (GL), as part of a balanced hypo-caloric diet, on anthropometric and biochemical parameters in patients with type 2 diabetes mellitus (T2DM). A total of 61 subjects with T2DM were randomly assigned to the intervention (n = 30) or to the control group (n = 31). Both groups followed the same hypo-caloric (-500 kcal) diet for 12 weeks. Consumption of four portions of low-GI/low-GL desserts/week was included in the diet in the intervention group while one portion of a favorite usual sweet/week was allowed to be consumed in the control group. Thirty subjects in the control and 28 subjects in the intervention group completed the trial. Body weight, body mass index, and waist circumference were reduced significantly in both groups. Arterial blood pressure, fasting blood glucose, glycosylated hemoglobin, insulin, and γ-GT were reduced significantly only in the intervention group; however, there were no significant differences between the two groups at endpoint. C-reactive protein was reduced in the intervention, and HDL cholesterol was also reduced in the control group; the reductions were significantly different at the end of the trial. No significant changes were observed in the other plasma lipids, uric acid, leptin, adiponectin, and interleukin-6 in either study group. Consumption of desserts with low GI/GL in a balanced hypo-caloric diet has a positive impact on anthropometric and metabolic parameters of patients with T2DM.

    Full Text Available Objective. To identify the degree of association between anthropometric indices and components of metabolic syndrome (MS and to determine optimal cut-off points of these indices for predicting MS in obese adolescents. Methods. A cross-sectional study with a sample of (n=110 Mexican obese adolescents grouped by sex and the presence/absence of MS. BMI percentile, waist circumference (WC, and waist-to-height ratio (WHtR were tested. ROC curves of the anthropometric indices were created to identify whether an index was a significant predictor of MS. Results. BMI percentile, WC, and WHtR were significantly correlated with systolic and diastolic blood pressure. As predictors of MS overall patients, the BMI percentile generated an area under curve (AUC of 0.651 (P=0.008, cut-off point above the 99th percentile. WC generated an AUC of 0.704 (P<0.001, cut-off point of ≥90 cm. WHtR demonstrated an AUC of 0.652 (P=0.008, cut-off point of 0.60. WHtR ≥0.62 and WHtR ≥0.61 generate AUC of 0.737 (P=0.006 and AUC of 0.717 (P=0.014 for predicting hypertension and insulin resistance, respectively, in females. Conclusion. WHtR is a better tool than WC and BMI for identifying cardiometabolic risk. The overall criterion (WHtR ≥ 0.6 could be appropriate for predicting MS in obese Mexican adolescents.

    This study was performed to quantify the effect of a 1-week freezer storage of urine on its calcium oxalate crystallization risk. Calcium oxalate is the most common urinary stone material observed in urolithiasis patients in western and affluent countries. The BONN-Risk-Index of calcium oxalate crystallization risk in human urine is determined from a crystallization experiment performed on untreated native urine samples. We tested the influence of a 1-week freezing on the BONN-Risk-Index value as well as the effect of the sample freezing on the urinary osmolality. In vitro crystallization experiments in 49 native urine samples from stone-forming and non-stone forming individuals were performed in order to determine their calcium oxalate crystallization risk according to the BONN-Risk-Index approach. Comparison of the results derived from original sample investigations with those obtained from the thawed aliquots by statistical evaluation shows that i) no significant deviation from linearity between both results exists and ii) both results are identical by statistical means. This is valid for both, the BONN-Risk-Index and the osmolality data. The differences in the BONN-Risk-Index results of both procedures of BONN-Risk-Index determination, however, exceed the clinically acceptable difference. Thus, determination of the urinary calcium oxalate crystallization risk from thawed urine samples cannot be recommended.

    To compare body mass index (BMI), waist circumference (WC), and body fat percentage (%BF), as index of overweight and obesity in young adults. We also intended to find an association between lifestyle behaviours and obesity. A cross-sectional study was conducted at Fatima Jinnah Dental College, Karachi, during 2007 to 2008, with 192 first year dental students, (18-21years) of high socioeconomic class. All were questioned regarding lifestyle behaviours. Overweight and obesity were estimated by measuring %BF, BMI, and WC. For %BF, skinfold thickness was measured using skinfold calipers. BMI > or = 23.0-24.9 kg/m2 was taken as overweight and > or = 25.0 kg/m2 as obese (Asians criteria proposed by Western Pacific Regional Office of World Health Organization). WC using Asian cutoff values for overweight and obesity were: males > or = 78 cm and > or = 90 cm; females > or = 72 cm and > or = 80 cm, respectively. Body fat percentage used to define overweight and obesity was: males 22.1-27.0 and > 27.1; females 27.1-32.0 and > 32.1, respectively. Pearson's correlation was done between the BMI, WC and %BF with statistical significance taken at P obese. Obesity was underpredicted by BMI when compared to skinfold calipers method. The obese were seen to skip breakfast more often [odds ratio (OR): 2.39], take frequent snacks (OR: 1.58), watch television more (OR: 1.58), and were physically less active than their non-obese counterparts. Body fat percentage using skinfold caliper is a reliable index of obesity. Lack of sleep and skipping of breakfast, are prominent promoters of obesity, in addition to other lifestyle behaviours.

    The relation between glycemic index, glycemic load, and subclinical coronary atherosclerosis is unknown. The aim of the study was to evaluate the associations between energy-adjusted glycemic index, glycemic load, and coronary artery calcium (CAC). This study was cross-sectional analysis of 28,429 asymptomatic Korean men and women (mean age 41.4 years) without a history of diabetes or cardiovascular disease. All participants underwent a health screening examination between March 2011 and April 2013, and dietary intake over the preceding year was estimated using a validated food frequency questionnaire. Cardiac computed tomography was used for CAC scoring. The prevalence of detectable CAC (CAC score >0) was 12.4%. In multivariable-adjusted models, the CAC score ratios (95% confidence intervals) comparing the highest to the lowest quintile of glycemic index and glycemic load were 1.74 (1.08 to 2.81; p trend = 0.03) and 3.04 (1.43 to 6.46; p trend = 0.005), respectively. These associations did not differ by clinical subgroups, including the participants at low cardiovascular risk. In conclusion, these findings suggest that high dietary glycemic index and glycemic load were associated with a greater prevalence and degree of CAC, with glycemic load having a stronger association.

    Governments have endorsed global targets to reduce childhood undernutrition as part of the Sustainable Development Goals. Understanding the socioeconomic differences in childhood undernutrition has the potential to be helpful for targeting policy to reach these goals. We specify a logistic regression model with the Composite Index of Anthropometric Failure (CIAF) as the outcome and indicator variables for wealth quartiles, maternal education categories and a set of covariates as explanatory variables. Wealth and education variables are interacted with a period indicator for 1990-2000 compared with 2001-2014 to observe differences over time. Based on these regressions we calculate predicted CIAF prevalence by wealth and education categories and over time. The sample included 146 surveys from 39 low-income and lower-middle-income countries with an overall sample size of 533 217 children. CIAF prevalence was 47.5% in 1990-2000, and it declined to 42.6% in 2001-2014. In 1990-2000 the CIAF prevalence of children with mothers with less than primary education was 31 percentage points higher than for mothers with secondary or higher education. This difference slightly decreased to 27 percentage points in 2001-2014. The difference in predicted CIAF prevalence of children from the highest and lowest wealth quartiles was 21 percentage points and did not change over time. We find evidence for persistent and even increasing socioeconomic inequalities in childhood undernutrition, which underlines the importance of previous calls for equity-driven approaches targeting the most vulnerable to reduce childhood malnutrition.

    Full Text Available Abstract Insufficient calcium intake has been proposed to cause unbalanced energy partitioning leading to obesity. However, weight loss interventions including dietary calcium or dairy product consumption have not reported changes in lipid metabolism measured by the plasma lipidome. Methods The objective of this study was to determine the relationships between dairy product or supplemental calcium intake with changes in the plasma lipidome and body composition during energy restriction. A secondary objective of this study was to explore the relationships among calculated macronutrient composition of the energy restricted diet to changes in the plasma lipidome, and body composition during energy restriction. Overweight adults (n = 61 were randomized into one of three intervention groups including a deficit of 500kcal/d: 1 placebo; 2 900 mg/d calcium supplement; and 3 3-4 servings of dairy products/d plus a placebo supplement. Plasma fatty acid methyl esters of cholesterol ester, diacylglycerol, free fatty acids, lysophosphatidylcholine, phosphatidylcholine, phosphatidylethanolamine and triacylglycerol were quantified by capillary gas chromatography. Results After adjustments for energy and protein (g/d intake, there was no significant effect of treatment on changes in weight, waist circumference or body composition. Plasma lipidome did not differ among dietary treatment groups. Stepwise regression identified correlations between reported intake of monounsaturated fat (% of energy and changes in % lean mass (r = -0.44, P P Conclusions Dairy product consumption or calcium supplementation during energy restriction over the course of 12 weeks did not affect plasma lipids. Independent of calcium and dairy product consumption, short-term energy restriction altered body composition. Reported dietary fat composition of energy restricted diets was associated with the degree of change in body composition in these overweight and obese individuals.

    Full Text Available Background. Although energy balance is the main factor that regulates body weight, recent studies suggest that calcium metabolism can modify the energy balance and help regulate body weight. Objective. To evaluate the association between the calcium intake in the diet and high body mass index in Mexican adults in the 20-59 age group. Material and methods. A cross-sectional secondary analytical study was conducted based on the 2006 Mexican National Health and Nutritional Survey (ENSANUT 2006. Food intake questionnaires applied to 16,494 adults were analyzed. After removing biologically implausible values or incomplete information, we arrived at a final sample of 15,662 adults grouped according to their body mass index. Linear regression was used to assess association between daily dietary calcium intake and body mass index. Results. There was an inverse association between dietary calcium consumption and a high body mass index. The mean calcium intake in subjects with normal body mass index was 903.9 mg/day versus 832.0 mg/day in obese subjects (p < 0.0001. Conclusion. The study corroborates existing evidence of an inverse association between the dietary calcium intake and a high body mass index.

    To test the usefulness of measuring pH and refractometry index, compared with measuring calcium carbonate concentration, of preparturient mammary gland secretions for predicting parturition in mares. Evaluation study. 27 pregnant Thoroughbred mares. Preparturient mammary gland secretion samples were obtained once or twice daily 10 days prior to foaling until parturition. The samples were analyzed for calcium carbonate concentration with a water hardness kit (151 samples), pH with pH test paper (222 samples), and refractometry index with a Brix refractometer (214 samples). The sensitivity, specificity, and positive and negative predictive values for each test were calculated for evaluation of predicting parturition. The PPV within 72 hours and the NPV within 24 hours for calcium carbonate concentration determination (standard value set to 400 μg/g) were 93.8% and 98.3%, respectively. The PPV within 72 hours and the NPV within 24 hours for the pH test (standard value set at 6.4) were 97.9% and 99.4%, respectively. The PPV within 72 hours and the NPV within 24 hours for the Brix test (standard value set to 20%) were 73.2% and 96.5%, respectively. Results suggested that the pH test with the standard value set at a pH of 6.4 would be useful in the management of preparturient mares by predicting when mares are not ready to foal. This was accomplished with equal effectiveness of measuring calcium carbonate concentration with a water hardness kit.

    Previous studies attempted to identify possible risk factors for acute and overuse injuries in several sports disciplines such as running, gymnastics or team sports. Given the lack of scientific works focused on risk factors for lower limb injuries in martial arts, the present study was aimed to investigate foot anatomy, anthropometric measures, and other background information as possible risk factors of injury in barefoot athletes practicing judo, karate, kung fu, thai boxe, or aikido. In addition, the injury rates were evaluated in relation with the different martial art styles. One group of 130 martial artists was retrospectively evaluated. Data of three foot morphological variables were collected: navicular height (NH), navicular drop (ND) and the rear foot (RF). In addition, each participant filled an interview questionnaire providing the following information: age, sex, body weight, height, BMI, hours of training per week, the kind of injury occurred to the lower limbs in the preceding year. Of 130 subjects, 70 (53.8%) did not sustain injuries, 35 (27.0%) suffered an acute injury and the remaining 25 (19.2%) reported an overuse injury. No significant differences were observed in the injury rates in relation to style and kind of martial art. Age, training volume and BMI were found as significant predictors of injury, while NH, ND and RF were not able to predict acute or overuse injury at lower limbs. The injury rates were similar in karate, judo, kung fu, aikido, and thai boxe. The foot morphology variables were not related with the presence or absence of acute and overuse injuries. Conversely, older and heavier martial artists, performing more hours of barefoot training, are at higher risk of acute and overuse injury. Athletic trainers should strongly take into account the present information in order to develop more accurate and specific injury prevention programs for martial artists.

    Multiparous early lactation Holstein cows (n = 16) were used in a randomized complete block design to determine the effects of feeding fatty acid calcium and the interaction of forage quality on production performance and biochemical indexes in early lactation cow. Treatments were as follows: (i) feeding low-quality forage without supplying fatty acid calcium (Diet A), (ii) feeding low-quality forage with supplying 400 g fatty acid calcium (Diet B), (iii) feeding high-quality forage without supplying fatty acid calcium (Diet C) and (iv) feeding high-quality forage with supplying 400 g fatty acid calcium. This experiment consisted 30 days. The milk and blood samples were collected in the last day of the trail. Intakes were recorded in the last 2 days of the trail. Supplementation of fatty acid calcium decreased significantly dry matter intake (DMI) (p < 0.01). Addition fatty acid calcium decreased milk protein percentage (p < 0.01) and milk SNF percentage (p < 0.01), but increased MUN (p < 0.05). Supplemented fatty acid decreased concentration of blood BHBA (p < 0.05), but increased TG, NEFA, glucagon, GLP-1, CCK, leptin, ApoA-IV, serotonin and MSH concentration in blood, the CCK concentration and feed intake showed a significant negative correlation (p < 0.05).

  20. Creatinine index as a surrogate of lean body mass derived from urea Kt/V, pre-dialysis serum levels and anthropometric characteristics of haemodialysis patients.

    Directory of Open Access Journals (Sweden)

    Bernard Canaud

    Full Text Available BACKGROUND AND OBJECTIVES: Protein-energy wasting is common in long-term haemodialysis (HD patients with chronic kidney disease and is associated with increased morbidity and mortality. The creatinine index (CI is a simple and useful nutritional parameter reflecting the dietary skeletal muscle protein intake and skeletal muscle mass of the patient. Because of the complexity of creatinine kinetic modeling (CKM to derive CI, we developed a more simplified formula to estimate CI in HD patients. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS: A large database of 549 HD patients followed over more than 20 years including monthly CKM-derived CI values was used to develop a simple equation based on patient demographics, predialysis serum creatinine values and dialysis dose (spKt/V using mixed regression models. RESULTS: The equation to estimate CI was developed based on age, gender, pre-dialysis serum creatinine concentrations and spKt/V urea. The equation-derived CI correlated strongly with the measured CI using CKM (correlation coefficient  = 0.79, p-value <0.001. The mean error of CI prediction using the equation was 13.47%. Preliminary examples of few typical HD patients have been used to illustrate the clinical relevance and potential usefulness of CI. CONCLUSIONS: The elementary equation used to derive CI using demographic parameters, pre-dialysis serum creatinine concentrations and dialysis dose is a simple and accurate surrogate measure for muscle mass estimation. However, the predictive value of the simplified CI assessment method on mortality deserves further evaluation in large cohorts of HD patients.

    STUDY OBJECTIVE: Shock index is a widely reported tool to identify patients at risk for circulatory collapse. We hypothesize that old age, diabetes, hypertension, and β- or calcium channel blockers weaken the association between shock index and mortality. METHODS: This was a cohort study of all...... first-time emergency department (ED) visits between 1995 and 2011 (n=111,019). We examined whether age 65 years or older, diabetes, hypertension, and use of β- or calcium channel blockers modified the association between shock index and 30-day mortality. RESULTS: The 30-day mortality was 3.0%. For all...... than or equal to 1 in patients aged 65 years or older was 8.2 (95% CI 7.2 to 9.4) compared with 18.9 (95% CI 15.6 to 23.0) in younger patients. β- Or calcium channel-blocked patients had an OR of 6.4 (95% CI 4.9 to 8.3) versus 12.3 (95% CI 11.0 to 13.8) in nonusers and hypertensive patients had...

    Full Text Available The aim of this study was to evaluate the relationship of dietary calcium intake with anthropometric measures, physical activity and adherence to the Mediterranean diet (MedDiet in 1176 Spanish children aged 6–9 years. Data were obtained from “Antropometría y Nutrición Infantil de Valencia” (ANIVA, a cross-sectional study of a representative sample. Dietary calcium intake assessed from three-day food records was compared to recommended daily intakes in Spain. Anthropometric measures (weight and height were measured according to international standards and adherence to the MedDiet was evaluated using the Mediterranean Diet Quality Index (KIDMED test. For the total sample of children, 25.8% had inadequate calcium intake, a significantly higher prevalence in girls (p = 0.006 and inadequate calcium intake was associated with lower height z-score (p = 0.001 for both sexes. In girls, there was an inverse relationship between calcium intake and body mass index (p = 0.001 and waist/hip ratio (p = 0.018. Boys presented a polarization in physical activity, reporting a greater level of both physical and sedentary activity in comparison with girls (p = 0.001. Children with poor adherence to MedDiet, even if they consume two yogurts or cheese (40 g daily, adjusted by gender, age, total energy intake, physical activity and father’s level of education, are at risk of inadequate total calcium intake (odds ratio adjusted [ORa]: 3.36, 95% confidence interval [CI]: 1.13–9.94, p = 0.001. The intake of these dairy products was insufficient to cover calcium intake recommendations in this age group (6–9 years. It is important to prioritize health strategies that promote the MedDiet and to increase calcium intake in this age group.

    Full Text Available Background: Importance of nutrition in human immunodeficiency virus (HIV is well-established; however, the information regarding the diet quality of people living with HIV (PLHIV especially in India is lacking. Objectives: The objective of this study is to assess the anthropometric and nutritional profile of Indian PLHIV. Material and Methods: The study was performed on 400 adult PLHIV registered at the Antiretroviral Center (ART center in New Delhi, India. Anthropometric data including height, weight, waist, hip, mid arm, and calf circumferences, were collected; 1-day 24-h dietary recall was done to gather nutrient intake from which nutrient adequacy ratios were computed. Mini Nutritional Assessment (MNA was also conducted. Results: The mean body mass index (BMI of the sample was 19.73 ± 3.55 kg/m 2 with around 40% having BMI <18.5 kg/m 2 . All anthropometric measurements were found to correlate positively and significantly with CD4 count (P < 0.05. The sample consumed poor quality of diet as they could not meet even the 2/3 rd of the Indian Council of Medical Research (2010 requirements for energy, protein, calcium, iron, riboflavin, niacin, folic acid, B12, copper, and zinc. Classification of subjects according to MNA indicated that more than 50% of the sample was at-risk of malnutrition and 34% were malnourished. With 40% of sample having BMI less than normal, 50% at risk of malnutrition together with poor nutrient intakes over a long period of time could contribute to further worsening of the nutritional status. Conclusion: There is a need to develop a database on nutritional profile of PLHIV in India which reinforces the need for development of effective strategies to improve their nutritional status.

    At present, there is a number of diagnostic imaging procedures allowing for the evaluation of atherosclerosis. The earliest, subclinical stage of atherosclerosis can be visualized with the development of computed tomography (CT) and ultrasound (US) techniques. Therefore, the purpose of this study was to assess the degree of coronary artery calcification and carotid intima-media thickness in diabetic subjects divided into different age groups. Fifty-six men, aged from 18 to 72 were included in the study. Participants were divided into 4 groups according to age (18–30, 31–45, 46–60 and more than 60 years). Two tests were performed: coronary calcium score (CS) determination and intima-media thickness (IMT) in ultrasound. CS was performed using a multi-slice scanner. Images were analyzed using the Agatson method. Ultrasound examinations were performed using a 9–12-MHz linear transducer. The correlation coefficient between calcium score index (CSI) and age of patients was 0.52 (p<0.001). The correlation between duration of diabetes and CSI was significantly lower (r=0.3; p<0.05). The increase of IMT is associated with age to a much greater extent and the correlation coefficient was 0.63 (p<0.001). IMT depended on the duration of diabetes, but the correlation was also weak (r=0.35; p<0.01). Comparison of the findings obtained in the presented study and in the group of healthy subjects proves that influence of diabetes on vascular deterioration may be observed, even among young individuals. Obtained results allow to make the following conclusions: 1. Calcium score index remains low in the group of male patients with diabetes before the age of 45. 2. Intima-media thickness correlates well with age (r=0.6; p<0.05) and weaker with the duration of diabetes (r=0.35; p<0.05). 3. IMT assessment may be a useful tool to identify the increased predisposition to atherosclerosis, also before the age of 30

    Obesity has been considered the key in metabolic syndrome (MetS) development, and fat accumulation may be responsible for the occurrence of metabolic abnormalities in hemodialysis patients. The use of gold-standard methods to evaluate obesity is limited, and anthropometric measures may be the simplest methods. However, no study has investigated the association between anthropometric indexes and MetS in these patients. Therefore, the aim was to determine which anthropometric indexes had the best association and prediction for MetS in patients undergoing hemodialysis. Cross-sectional study that included patients older than 18 years, undergoing hemodialysis for at least 3 months. Patients with liver disease and cancer or those receiving corticosteroids or antiretroviral therapy were excluded. Diagnostic criteria from Harmonizing Metabolic Syndrome were used for the diagnosis of MetS. Anthropometric indexes evaluated were body mass index (BMI); percent standard of triceps skinfold thickness and of middle arm muscle circumference; waist circumference (WC); sagittal abdominal diameter; neck circumference; waist-to-hip, waist-to-thigh, and waist-to-height ratios; sagittal index; conicity index; and body fat percentage. Ninety-eight patients were included, 54.1% male, and mean age was 57.8 ± 12.9 years. The prevalence of MetS was 74.5%. Individuals with MetS had increased accumulation of abdominal fat and general obesity. Waist-to-height ratio was the variable independently associated with MetS diagnosis (odds ratio, 1.21; 95% confidence interval, 1.09-1.34; P < .01) and that better predicts MetS, followed by WC and BMI (area under the curve of 0.840, 0.836, and 0.798, respectively, P < .01). Waist-to-height ratio was the best anthropometric predictor of MetS in maintenance hemodialysis patients. © 2015 American Society for Parenteral and Enteral Nutrition.

    The impact of race/ethnicity upon facial anthropometric data in the US workforce, on the development of personal protective equipment, has not been investigated to any significant degree. The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of 3997 US civilian workers. Survey participants were divided into two gender groups, four racial/ethnic groups, and three age groups. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques. A multivariate analysis of the data was performed using Principal Component Analysis. An exploratory analysis to determine the effect of different demographic factors had on anthropometric features was assessed via a linear model. The 21 anthropometric measurements, body mass index, and the first and second principal component scores were dependent variables, while gender, ethnicity, age, occupation, weight, and height served as independent variables. Gender significantly contributes to size for 19 of 24 dependent variables. African-Americans have statistically shorter, wider, and shallower noses than Caucasians. Hispanic workers have 14 facial features that are significantly larger than Caucasians, while their nose protrusion, height, and head length are significantly shorter. The other ethnic group was composed primarily of Asian subjects and has statistically different dimensions from Caucasians for 16 anthropometric values. Nineteen anthropometric values for subjects at least 45 years of age are statistically different from those measured for subjects between 18 and 29 years of age.

    Worldwide increase in the prevalence of abnormal anthropometric indices (i.e., body mass index (BMI), and waist circumference (WC)) are associated with increased risk of death and adverse health outcomes which causes great burden in public health. Studies on the association between radiation exposure and altered anthropometric indices reported both positive and negative associations in atomic bomb and childhood cancer survivors. We have initiated a radiologic technologists health study to investigate occupational radiation exposure and their health effects. Therefore, this study aims to investigate the association between occupational radiation dose with BMI and WC in radiologic technologists in South Korea. These results explain that occupational radiation exposure can possibly alter BMI and WC. Therefore, further study is required to verify the prospective causal effect of radiation exposure on anthropometric indices.

    The aim of this study was to investigate the dietary intakes and anthropometric profiles of county and club Gaelic football players and compare them to soccer players and control subjects. Seven-day dietary records were analyzed and anthropometric measurements were taken midway through the Gaelic football competitive season. The county group with a mean height of 1.82 +/- 0.04 m were significantly taller (p soccer players and 159 +/- 8 kJ x kg(-1) x day(-1) for the controls, with 57 +/- 4% and 44.9 +/- 5% of their energy from carbohydrate. The nature of Gaelic football demands a balanced diet, rich in energy and carbohydrate and with adequate calcium is consumed; the subjects needed to increase these dietary components in order to meet the energetic demands of competition and training. Additional nutritional counseling was provided on an individual basis.

    Several studies have shown good short-term outcomes after surgery for sagittal synostosis. However, the improvement in head shape usually regresses over the long term. The aim of this study was to compare anthropometric changes after surgery between osteoplastic expansion surgery and distraction osteogenesis for correcting sagittal synostosis. From November 2002 through December 2008, 17 patients with sagittal synostosis were analyzed. Anthropometric changes were assessed with cephalic indices obtained with computed tomography of the skull. The age of the patients at the time of surgery ranged from 2 to 25 months (mean, 8.2 months), and the follow-up period ranged from 6 to 63 months (mean, 17 months). In 16 patients, the cephalic index showed improvement immediately after surgery but gradually decreased in the follow-up period. The improving rate was decreased more after osteoplastic expansion surgery than after distraction osteogenesis (p<0.01). Although long-term follow-up is necessary, morphological improvement persists to a greater degree after distraction surgery. (author)

    Human peripheral lymphocytes from whole blood cultures were exposed to either soluble form of nickel carbonate hydroxide (NiCH) (0-60 {mu}M), or of nickel subsulfide (Ni{sub 3}S{sub 2}) (0-120 {mu}M), or of nickel oxide (NiO) (0-120 {mu}M), or nickel sulfate (NiSO{sub 4}) (0-120 {mu}M) for a short duration of 2 h. The treatments occurred 46 h after the beginning of the cultures. The cultures were harvested after a total incubation of 72 h, and sister-chromatid exchange (SCE), replication index (RI), and mitotic index (MI) were measured for each nickel compound. The soluble form of NiCH at 30 {mu}M but those of Ni{sub 3}S{sub 2} and NiO at 120 {mu}M produced significant increase in the SCE per cell compared to the control value, whereas NiSO{sub 4} failed to produce any such significant increase. Except NiSO{sub 4}, the soluble forms of NiCH, Ni{sub 3}S{sub 2}, and NiO produced significant cell-cycle delay (as measured by the inhibition of RI) as well as significant inhibition of the MI at respective similar concentrations as mentioned above. Pretreatment of human blood lymphocytes with catalase (H{sub 2}O{sub 2} scavenger), or superoxide dismutase (superoxide anion scavenger), or dimethylthiourea (hydroxyl radical scavenger), or deferoxamine (iron chelator), or N-acetylcysteine (general antioxidant) inhibited NiCH-induced SCE, and changes in RI and MI. This suggests the participation of oxidative stress involving H{sub 2}O{sub 2}, the superoxide anion radical, the hydroxyl radical, and iron in the NiCH-induced genotoxic responses. Cotreatment of NiCH with either verapamil (inhibitor of intracellular calcium ion ([Ca{sup 2+}]{sub i}) movement through plasma membranes), or dantrolene (inhibitor of [Ca{sup 2+}]{sub i} release from sarcoplasmic reticulum), or BAPTA (Ca{sup 2+} chelator) also inhibited the NiCH-induced responses. These results suggest that [Ca{sup 2+}]{sub i} is also implicated in the genotoxicity of NiCH. Overall these data indicate that various types

    Some questions remain regarding the anthropometric differences between the feet of young men and women, but the gap is much greater when dealing with older adults. No studies were found concerning these differences in an exclusively older adult population, which makes it difficult to manufacture shoes based on the specific anthropometric measurements of the older adult population and according to gender differences. To identify differences between the anthropometric foot variables of older men and women. Cross-sectional. 154 older women (69.0 ± 6.8 y) and 131 older men (69.0 ± 6.5 y). The foot evaluations comprised the variables of width, perimeter, height, length, 1st and 5th metatarsophalangeal angles, the Arch Index (AI), and the Foot Posture Index (FPI). A data analysis was performed using t test and a post hoc power analysis. Women showed significantly higher values for the width and perimeter of the toes, width of the metatarsal heads, and width of the heel and presented significantly lower values for the height of the dorsal foot after normalization of the data to foot length. The 1st and 5th metatarsophalangeal angles were smaller in the men. There were no differences between men and women with respect to AI and FPI. Overall, the current study shows evidence of differences between some of the anthropometric foot variables of older men and women that must be taken into account for the manufacture of shoes for older adults.

    Full Text Available Background: Vitamin D has been linked to health conditions and many serious diseases including cardiovascular, diabetes, and cancer. This study was conducted to determine the correlation between vitamin D with diet quality, sun exposure, physical activity, sociodemographic, and anthropometrics indices. Methods: In a cross-sectional study, 180 subjects (90 males and 90 females aged from 14 to 57 years were enrolled. A questionnaire was used to collect sociodemographic and anthropometric data, physical activity and food intake information. The correlation between serum vitamin D with these variables was analyzed. Results: Significant difference was noted between two genders regarding age, weight, body mass index, waist circumference, job, income, physical activity, LDL, HDL, TG, and cholesterol. Low quality diets denoted to a mean global score of 47±6.3 and 46±6.4 in male and females, respectively. No significant difference was found between diet quality, calcium intake (1310±734 mg, and vitamin D intake (1.8±1.5 mg with serum vitamin D level. Further analysis revealed that there was a significant positive correlation between cholesterol and saturated fat intake and serum vitamin D. Between two genders, the correlation between physical activity (p<0.005, sitting time(p<0.04, and income (p<0.04 with serum vitamin D level was significant. Conclusion: Based on significant correlation between serum vitamin D level, with cholesterol, saturated fat intake, physical activity and income, we can conclude that physical activity has correlation with a favorable vitamin D status.

    Background: Coronary atherosclerosis has traditionally been proposed to be associated with several cardiovascular risk factors and anthropometric measures. However, clinical data regarding the independent value of visceral adipose tissue in addition to such traditional predictors remains obscure. Materials and methods: We subsequently studied 719 subjects (age: 48.1 ± 8.3 years, 25% females) who underwent multidetector computed tomography (MDCT) for coronary calcium score (CCS) quantification. Baseline demographic data and anthropometric measures were taken with simultaneous body fat composition estimated. Visceral adipose tissue of pericardial and thoracic peri-aortic fat was quantified by MDCT using TeraRecon Aquarius workstation (San Mateo, CA). Traditional cardiovascular risk stratification was calculated by metabolic (NCEP ATP III) and Framingham (FRS) scores and high-sensitivity CRP (Hs-CRP) was taken to represent systemic inflammation. The independent value of visceral adipose tissue to systemic inflammation and CCS was assessed by utilizing multivariable regression analysis. Results: Of all subjects enrolled in this study, the mean values for pericardial and peri-aortic adipose tissue were 74.23 ± 27.51 and 7.23 ± 3.69 ml, respectively. Higher visceral fat quartile groups were associated with graded increase of risks for cardiovascular diseases. Both adipose burdens strongly correlated with anthropometric measures including waist circumference, body weight and body mass index (all p < 0.001). In addition, both visceral amount correlates well with ATP and FRS scores, all lipid profiles and systemic inflammation marker in terms of Hs-CRP (all p < 0.001). After adjustment for baseline variables, both visceral fat were independently related to Hs-CRP levels (all p < 0.05), but only pericardial fat exerted independent role in coronary calcium deposit. Conclusion: Both visceral adipose tissues strongly correlated with systemic inflammation beyond traditional

    Full Text Available The aim of this study was to compare body image and anthropometric indicators among adolescents living with HIV and healthy adolescents (control group. In addition, we verified the associations of anthropometric indicators, infection/treatment, sexual maturity, and sociodemographic characteristics with body image in adolescents living with HIV. One hundred and eleven adolescents aged 10 to 15 years were divided into those living with HIV (n = 57 and a control group (n = 54. Body image was investigated using an eight-point body silhouette scale. Body weight, height, circumferences, and skinfolds were measured. Body image dissatisfaction was found in 54.4% of the adolescents living with HIV, with 38.6% of them wishing to increase their body size. Conversely, body image dissatisfaction was due to the desire to reduce body size in the control group (40.7%. No difference between the HIV and control groups was found for the anthropometric indicators analyzed. Gender (β = -0.52, age (β = 0.18, body weight (β = 0.07, body mass index (β = -0.19, and upper arm muscle area (β = -0.08 explained 42% of the variation in the body image score of adolescents living with HIV. Thinness is the main reason for body image dissatisfaction in adolescents living with HIV. Almost half the body dissatisfaction of adolescents living with HIV was explained by demographic and anthropometric variables.

    Full Text Available Synchronized swimming and aerobic gymnastics are competitive sports that have grown in popularity throughout the Slovakia and around the world. Unfortunately, a paucity of research exists either on anthropometric and physiological characteristics or physical benefits of these sports. The present study examined anthropometric and cardiovascular characteristics of control group - CO (n = 10 in comparison to competitive synchronized swimmers - SS (n = 11 and aerobic gymnasts - AG (n = 10 between the ages of 13 and 25 years. The physical measures were assessed per the protocols in the following order: height (BH, weight (BW, body mass index (BMI, and % body fat (% BF. The measurements of maximal oxygen consumption (VO2max and maximum heart rate (HRmax were examined by spiroergometry via COSMED K4b2. All measurements were collected by trained data collection staff. An analysis of variance (Kruskal - Wallis with a Mann-Whitney U test for the significant effect among the three groups showed that aerobic gymnasts were taller than synchronized swimmers and control group (p = .02. Training and conditioning requirements specific for the two athletic groups caused that AG and SS have higher level of VO2max (p = .02 and VO2max.kg-1 (p = .00, and also lower level of the body weight (p= .01, BMI (p = .01 and the % BF (p = .00. These findings confirm that selected parameters are considered the bases for success in elite sports. This information could also help to design specific training and evaluate the adaptation to training stimuli with the aim to maximize sport performance.

    The methods most commonly used to measure the absorption and retention of orally administered calcium are reviewed. Nearly all make use of calcium radioisotopes. The magnitude of calcium absorption and retention depends upon the chemical form and amount of calcium administered, and the clinical and nutritional status of the subject; these influences are briefly surveyed.

    The dietary inflammatory index (DII) is a new tool to assess the inflammatory potential of the diet. In the present study, we aimed to determine the association between the DII and BMI, waist circumference and waist:height ratio (WHtR). We conducted a cross-sectional study of 7236 participants recruited into the PREvención con DIeta MEDiterránea trial. Information from a validated 137-item FFQ was used to calculate energy, food and nutrient intakes. A fourteen-item dietary screener was used to assess adherence to the Mediterranean diet (MeDiet). Sex-specific multivariable linear regression models were fitted to estimate differences (and 95% CI) in BMI, waist circumference and WHtR across the quintiles of the DII. All nutrient intakes, healthy foods and adherence to the MeDiet were higher in the quintile with the lowest DII score (more anti-inflammatory values) except for intakes of animal protein, saturated fat and monounsaturated fat. Although an inverse association between the DII and total energy was apparent, the DII was associated with higher average BMI, waist circumference and WHtR after adjusting for known risk factors. The adjusted difference in the WHtR for women and men between the highest and lowest quintiles of the DII was 1.60% (95% CI 0.87, 2.33) and 1.04% (95% CI 0.35, 1.74), respectively. Pro-inflammatory scores remained associated with obesity after controlling for the effect that adherence to a MeDiet had on inflammation. In conclusion, the present study shows a direct association between the DII and indices of obesity, and supports the hypothesis that diet may have a role in the development of obesity through inflammatory modulation mechanisms.

    Both genetic and environmental factors are known to affect body mass index (BMI), but detailed understanding of how their effects differ during childhood and adolescence is lacking. We analyzed the genetic and environmental contributions to BMI variation from infancy to early adulthood and the ways they differ by sex and geographic regions representing high (North America and Australia), moderate (Europe), and low levels (East Asia) of obesogenic environments. Data were available for 87,782 complete twin pairs from 0.5 to 19.5 y of age from 45 cohorts. Analyses were based on 383,092 BMI measurements. Variation in BMI was decomposed into genetic and environmental components through genetic structural equation modeling. The variance of BMI increased from 5 y of age along with increasing mean BMI. The proportion of BMI variation explained by additive genetic factors was lowest at 4 y of age in boys (a(2) = 0.42) and girls (a(2) = 0.41) and then generally increased to 0.75 in both sexes at 19 y of age. This was because of a stronger influence of environmental factors shared by co-twins in midchildhood. After 15 y of age, the effect of shared environment was not observed. The sex-specific expression of genetic factors was seen in infancy but was most prominent at 13 y of age and older. The variance of BMI was highest in North America and Australia and lowest in East Asia, but the relative proportion of genetic variation to total variation remained roughly similar across different regions. Environmental factors shared by co-twins affect BMI in childhood, but little evidence for their contribution was found in late adolescence. Our results suggest that genetic factors play a major role in the variation of BMI in adolescence among populations of different ethnicities exposed to different environmental factors related to obesity. © 2016 American Society for Nutrition.

    This study aims to explore the association of anthropometric indices of obesity with hypertension in Chinese elderly and its possible gender and age differences. A total of 7070 adults age 60 or older were interviewed in a cross-sectional study conducted in 2017. Anthropometric indices for each participant were measured by using standard methods of trained doctoral/master students. We performed two binary logistic regression models to examine the association of the nine different anthropometric indices and hypertension by gender. Lastly, analyses were performed in two steps stratified for age. Comparing individuals with and without hypertension, there were statistically significant differences in anthropometric indices except height, a body shape index (ABSI), and hip index (HI) in males; and except height in females. There were gender differences in the relationship between anthropometric indices and the prevalence of hypertension in Chinese older adults. After stratification by age, the associations of all anthropometric indices became weaker, disappeared, or even went in the opposite direction. Furthermore, body mass index (BMI) in men (except individuals older than 80) and hip circumference (HC) in women showed a significant impact on the risk of hypertension. The association of anthropometric indices of obesity with hypertension in Chinese elderly differ by gender and age. These findings indicate a need to develop gender-specific strategies for the male and female elderly in the primary and secondary prevention of hypertension.

    Previous research has shown that today's crane cabins fail to meet the needs of a large proportion of operators. Performance and financial losses and effects on safety should not be overlooked as well. The first aim of this survey is to model the crane cabin interior space using up-to-date crane operator anthropometric data and to compare the multivariate and univariate method anthropometric models. The second aim of the paper is to define the crane cabin interior space dimensions that enable anthropometric convenience. To facilitate the cabin design, the anthropometric dimensions of 64 crane operators in the first sample and 19 more in the second sample were collected in Serbia. The multivariate anthropometric models, spanning 95% of the population on the basis of a set of 8 anthropometric dimensions, have been developed. The percentile method was also used on the same set of data. The dimensions of the interior space, necessary for the accommodation of the crane operator, are 1174×1080×1865 mm. The percentiles results for the 5th and 95th model are within the obtained dimensions. The results of this study may prove useful to crane cabin designers in eliminating anthropometric inconsistencies and improving the health of operators, but can also aid in improving the safety, performance and financial results of the companies where crane cabins operate.

    Several observations of body size, shape, posture, and configuration were made to document changes resulting from direct effects of weightlessness during the Skylab 4 mission. After the crewmen were placed in orbit, a number of anatomical and anthropometric changes occurred including a straightening of the thoracolumbar spine, a general decrease in truncal girth, and an increase in height. By the time of the earliest in-flight measurement on mission day 3, all crewmen had lost more than two liters of extravascular fluid from the calf and thigh. The puffy facies, the bird legs effect, the engorgement of upper body veins, and the reduced volume of lower body veins were all documented with photographs. Center-of-mass measurements confirmed a fluid shift cephalad. This shift remained throughout the mission until recovery, when a sharp reversal occurred; a major portion of the reversal was completed in a few hours. The anatomical changes are of considerable scientific interest and of import to the human factors design engineer, but the shifts of blood and extravascular fluid are of more consequence. It is hypothesized that the driving force for the fluid shift is the intrinsic and unopposed lower limb elasticity that forces venous blood and then other fluid cephalad.

It intended to analyse the bone mineral density (BMD of menopausal women through the bone densitometry test (DO in the lumbar region (L1 to L4, femoral neck and total femur, and also use Bouchard’s self-recall of daily activities; employing the food record from Buker and Stuart to dose and quantify the daily intake of calcium and vitamin D. The data were analysed via Kolmogorov-Smirnov’s test, and default value of α = 0.05 was set to compare the BMD averages. It was observed that one hundred percent of the assessed individuals had a BMD level below the average fixed by WHO: 14.4% with osteopenia and 85.6% with osteoporosis; a lower BMD in the femoral area (0.721g and the biggest loss among the sedentary ones (0.698g. It was noticed that there was a correlation between the physical activities and the BMD only when associated with anthropometric standards and the daily ingestion of vitamin D.

    Overweight and obesity during working life are becoming an increasingly serious challenge to various professional groups where recruits and personnel must be healthy and fit. Marine recruitment, even at the training stage, should be open to applicants who meet health and fitness criteria. The objective of the study is to determine the overweight and adiposity rates among seafarer candidates (n = 368). Based on anthropometric measurements and somatic indices the extent of obesity among marine students/ /future seafarers was investigated. In the groups identified according to the year of study, arithmetic averages (SD - standard deviation) were calculated for somatometric characteristics, and were then used to analyse the phenomena of overweight and obesity. The comparison was performed using the Kruskal-Wallis test, one-way analysis of variance (ANOVA) by ranks. The highest average body mass index (BMI) score was found in fourth-year students (mean BMI 25.7 ± 2.8). The average BMI for years one and two was in the upper range of 'healthy' weight. In 24.0% of first-year students and 32.2% of second-year students, the waist circumference was higher than half of the body height. Body fat percentage results indicate that this feature is highly variable, with a strong upward trend. Findings regarding overweight among future seamen give cause for concern. The participants of the study were characterised by excessive weight and adiposity. Recruitment criteria for uniformed services are not as restrictive as they used to be, as it is getting increasingly more difficult to find sufficiently slim and fit applicants.

    Full Text Available Introduction: Polyarticular hypermobility manifests in an increased range of motion in the joints compared to standards that include gender and age. It is given that it occurs even in 30% of children. It can lead to many biomechanical disorders and injuries. Science, which describes the measurement of the different body parameters such as height, body weight or fat content in the body is anthropometry and it was used to characterize the child diagnosed with arthritis polyarticular hypermobility. Material and Methods: The study was conducted on the group of 35 children aged 6 to 11 years old with diagnosed polyarticular hypermobility. The control group were randomly selected children in the same age from the same school without diagnosed polyarticular hypermobility. Anthropometric parameters of all children were measured according to accepted methods. The children were tested for body weight, height, body mass index, WHR index and their skinfolds were measured by skinfolds calipers. Objective: The aim of this study was to evaluate the anthropometric parameters of children with diagnosed polyarticular hypermobility and to compare these results to their contemporaries with no identified polyarticular hypermobility. Results: All the examined parameters (height, body weight, BMI, WHR, skinfolds measurement in the two groups were on very similar levels, there were no statistically significant differences (BMI p = 0.3435, WHR p = 0.806. Conclusions: There is no significant difference between the study group and the control group in the examined anthropometric parameters (height, body weight and BMI. Children with diagnosed polyarticular hypermobility in terms of weight and height do not stand out from their peers.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p530   Anthropometric indicators enable professionals for predicting risk of falls in the elderly; however, there is a gap in literature on reference values. This study analyzes anthropometric indicators such as screening tests for falls in the elderly. Cross-sectional population-based systematic sampling was conducted through a household survey and body composition assessment. Anthropometric measurements were performed using portable electronic scale and stadiometer. Bioimpedance device was used to measure body mass index, body fat and lean body mass. Falls were evaluated in the 12 months preceding the interview as a dependent variable. Discriminatory analysis was performed for falls through the ROC curve, sensitivity, specificity, positive and negative predictive values. Overall, 275 older adults participated in this study, whose prevalence of falls was 23.6%. The average body mass index was 27.8kg/cm2 and 52.1% of individuals were overweight. Among older men, height (ROC=0.68; 95%CI 0.54-0.78 and lean body mass (ROC=0.63, 95%CI 0.58- 0.76 were associated to the occurrence of falls. When considering cutoff of 52.2kg and 166cm, sensitivity was obtained in 75% and high negative predictive values (88.1% and 89.1% respectively. For women, lean body mass (ROC=0.61, 95%CI 0.30-0.49 and body mass (ROC=0.60, 95%CI 0.53-0.72 were relevant from the optimal cutoff point of 28.9% and 57.2kg/m2. Lean body mass was more sensitive (63.2% and body mass little more specific (64.3%, both with high negative predictive values (82.0% and 83.0%. The indicators used were able to discriminate older adults who have suffered from falls.

    Typical training programmes in elite race walkers involve high training volumes at low and moderate intensities, which have been reported to induce functional and structural adaptations at an anthropometric level. Since anthropometrical variables are closely related to movement efficiency and performance in endurance events, the aim of this study was to describe the anthropometric profile of world-class race walkers. Twenty-nine world-class race walkers (21 men & 8 women) participated in this study. Anthropometric characteristics, including height, body mass, eight skinfolds, five girths and four bone breadths were measured. Body composition, somatotype, somatotype dispersion mean, somatotype attitudinal mean and height to weight ratio, as well as skinfolds extremity to trunk ratio were also calculated. Mean height, body mass and body mass index were 177.1 ± 7.1 cm, 66.4 ± 5.8 kg, and21.2±1.3kg·m2 formenand165.6±4.5cm,53.6±3.7kg,and19.6±1.6kg·m2for women, respectively. Women presented greater body fat content (6.7 ± 0.6 vs. 12.2 ± 0.8%; very large effect), less muscle mass (65.6 ± 4.6 vs. 61.6 ± 2.6 kg; large effect), and were more endomorphic (large effect) than men. Men specialists in 20-km showed greater muscle mass (66.7 ± 4.9 vs. 64.4 ± 4.3 kg; moderate effect), and slightly higher skinfolds, girths, body fat content and were more mesomorphic than 50-km specialists (moderate effect). The present study expands the limited knowledge on the anthropometric characteristics and somatotype elements of elite top-class race walkers. The characterisation of the morphology of elite race walkers provides coaches a reference values to control the training development of the race walker, as well as providing reference values to improve talent identification.

    To investigate the agreement in evaluation of risk of developing cardiovascular diseases based on anthropometric parameters in young adults. The study included 406 students, measuring weight, height, and waist and neck circumferences. Waist-to-height ratio and the conicity index. The kappa coefficient was used to assess agreement in risk classification for cardiovascular diseases. The positive and negative specific agreement values were calculated as well. The Pearson chi-square (χ"2) test was used to assess associations between categorical variables (p<0.05). The majority of the parameters assessed (44%) showed slight (k=0.21 to 0.40) and/or poor agreement (k<0.20), with low values of negative specific agreement. The best agreement was observed between waist circumference and waist-to-height ratio both for the general population (k=0.88) and between sexes (k=0.93 to 0.86). There was a significant association (p<0.001) between the risk of cardiovascular diseases and females when using waist circumference and conicity index, and with males when using neck circumference. This resulted in a wide variation in the prevalence of cardiovascular disease risk (5.5%-36.5%), depending on the parameter and the sex that was assessed. The results indicate variability in agreement in assessing risk for cardiovascular diseases, based on anthropometric parameters, and which also seems to be influenced by sex. Further studies in the Brazilian population are required to better understand this issue

    Millions of workers in China rely on respirators and other personal protective equipment to reduce the risk of injury and occupational diseases. However, it has been >25 years since the first survey of facial dimensions for Chinese adults was published, and it has never been completely updated. Thus, an anthropometric survey of Chinese civilian workers was conducted in 2006. A total of 3000 subjects (2026 males and 974 females) between the ages of 18 and 66 years old was measured using traditional techniques. Nineteen facial dimensions, height, weight, neck circumference, waist circumference and hip circumference were measured. A stratified sampling plan of three age strata and two gender strata was implemented. Linear regression analysis was used to evaluate the possible effects of gender, age, occupation and body size on facial dimensions. The regression coefficients for gender indicated that for all anthropometric dimensions, males had significantly larger measurements than females. As body mass index increased, dimensions measured increased significantly. Construction workers and miners had significantly smaller measurements than individuals employed in healthcare or manufacturing for a majority of dimensions. Five representative indexes of facial dimension (face length, face width, nose protrusion, bigonial breadth and nasal root breadth) were selected based on correlation and cluster analysis of all dimensions. Through comparison with the facial dimensions of American subjects, this study indicated that Chinese civilian workers have shorter face length, smaller nose protrusion, larger face width and longer lip length.

    To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/ length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.

  10. Calcium waves.

    Waves through living systems are best characterized by their speeds at 20 degrees C. These speeds vary from those of calcium action potentials to those of ultraslow ones which move at 1-10 and/or 10-20 nm s(-1). All such waves are known or inferred to be calcium waves. The two classes of calcium waves which include ones with important morphogenetic effects are slow waves that move at 0.2-2 microm s(-1) and ultraslow ones. Both may be propagated by cycles in which the entry of calcium through the plasma membrane induces subsurface contraction. This contraction opens nearby stretch-sensitive calcium channels. Calcium entry through these channels propagates the calcium wave. Many slow waves are seen as waves of indentation. Some are considered to act via cellular peristalsis; for example, those which seem to drive the germ plasm to the vegetal pole of the Xenopus egg. Other good examples of morphogenetic slow waves are ones through fertilizing maize eggs, through developing barnacle eggs and through axolotl embryos during neural induction. Good examples of ultraslow morphogenetic waves are ones during inversion in developing Volvox embryos and across developing Drosophila eye discs. Morphogenetic waves may be best pursued by imaging their calcium with aequorins.

    To analyze the predictive capacity of anthropometric indicators and their cut-off values for dyslipidemia screening in children and adolescents. This was a cross-sectional study involving 1139 children and adolescents, of both sexes, aged 6-18 years. Body weight, height, waist circumference, subscapular, and triceps skinfold thickness were measured. The body mass index and waist-to-height ratio were calculated. Children and adolescents exhibiting at least one of the following lipid alterations were defined as having dyslipidemia: elevated total cholesterol, low high-density lipoprotein, elevated low-density lipoprotein, and high triglyceride concentration. A receiver operating characteristic curve was constructed and the area under the curve, sensitivity, and specificity was calculated for the parameters analyzed. The prevalence of dyslipidemia was 62.1%. The waist-to-height ratio, waist circumference, subscapular, body mass index, and triceps skinfold thickness, in this order, presented the largest number of significant accuracies, ranging from 0.59 to 0.78. The associations of the anthropometric indicators with dyslipidemia were stronger among adolescents than among children. Significant differences between accuracies of the anthropometric indicators were only observed by the end of adolescence; the accuracy of waist-to-height ratio was higher than that of subscapular (p=0.048) for females, and the accuracy of waist circumference was higher than that of subscapular (p=0.029) and body mass index (p=0.012) for males. In general, the cut-off values of the anthropometric predictors of dyslipidemia increased with age, except for waist-to-height ratio. Sensitivity and specificity varied substantially between anthropometric indicators, ranging from 75.6 to 53.5 and from 75.0 to 50.0, respectively. The anthropometric indicators studied had little utility as screening tools for dyslipidemia, especially in children. Copyright © 2015 Sociedade Brasileira de Pediatria

  12. Evolution of the Calcium Paradigm: The Relation between Vitamin D, Serum Calcium and Calcium Absorption

    Full Text Available Osteoporosis is the index disease for calcium deficiency, just as rickets/osteomalacia is the index disease for vitamin D deficiency, but there is considerable overlap between them. The common explanation for this overlap is that hypovitaminosis D causes malabsorption of calcium which then causes secondary hyperparathyroidism and is effectively the same thing as calcium deficiency. This paradigm is incorrect. Hypovitaminosis D causes secondary hyperparathyroidism at serum calcidiol levels lower than 60 nmol/L long before it causes malabsorption of calcium because serum calcitriol (which controls calcium absorption is maintained until serum calcidiol falls below 20 nmol/L. This secondary hyperparathyroidism, probably due to loss of a “calcaemic” action of vitamin D on bone first described in 1957, destroys bone and explains why vitamin D insufficiency is a risk factor for osteoporosis. Vitamin D thus plays a central role in the maintenance of the serum (ionised calcium, which is more important to the organism than the preservation of the skeleton. Bone is sacrificed when absorbed dietary calcium does not match excretion through the skin, kidneys and bowel which is why calcium deficiency causes osteoporosis in experimental animals and, by implication, in humans.

The study included 736 women (≥ 18 years. Anthropometric variables (weight, height, waist circumference were collected for the determination of body mass index, waist-height ratio, and conicity index. Body image perception was evaluated using a nine-body silhouette scale. The prevalence of body image dissatisfaction was 73% (dissatisfaction due to excess weight = 67.4%; dissatisfaction due to thinness = 5.6%. Overweight women (PR=1.34; 95%CI=1.23-2.49, p<0.001 and women with an inadequate conicity index (PR=1.12; 95%CI =1.02-1.24, p=0.016 presented a higher prevalence of body image dissatisfaction. The prevalence of body image dissatisfaction is high and the proportion of inadequate anthropometric indicators requires attention. Moreover, body dissatisfaction was more prevalent among overweight women and women with an inadequate conicity index. These results indicate the need for interventions and for the implementation of programs designed to control body weight and to reduce cardiovascular risk factors and body image dissatisfaction in women attending primary health care centers, such as cancer screening services.

    It has been shown that obesity is associated with increased rates of dyslipidemia. The present work revisits the association between plasma lipid levels and classical indicators of obesity including body mass index (BMI). The significance of various anthropometric/metabolic variables in clinical assessment of type and severity of dyslipidemia was also determined. Recently described body indices, a body shape index (ABSI) and body roundness index (BRI), were also assessed in this context. For the present cross-sectional analytical study, the participants (n = 275) were recruited from the patients visiting different health camps. Participants were anthropometrically measured and interviewed, and their fasting intravenous blood was collected. Plasma lipid levels were accordingly determined. The values for different anthropometric parameters are significantly different between dyslipidemic and non-dyslipidemic participants. Receiver operating characteristics curve analyses revealed that all the tested variables gave the highest area under the curve (AUC) values for predicting hypertriglyceridemia in comparison to other plasma lipid abnormalities. BRI gave slightly higher AUC values in predicting different forms of dyslipidemia in comparison to BMI, whereas ABSI gave very low values. Several anthropometric/metabolic indices display increased predictive capabilities for detecting hypertriglyceridemia in comparison to any other form of plasma lipid disorders. The capacity of BRI to predict dyslipidemia was comparable but not superior to the classical indicators of obesity, whereas ABSI could not detect dyslipidemia.

    This study compared the efficacy of angiotensin receptor blockers (ARBs) and calcium channel blockers (CCBs) in the effect of insulin resistance (IR) as assessed using the homeostasis model assessment of insulin resistance (HOMA-IR) in non-diabetic patients. The MEDLINE, EMBASE, and Cochrane Library databases were searched to identify studies published before December 2012 that investigated the use of ARBs and CCBs to determine the effect on the HOMA-IR index in non-diabetics. Parameters on IR and blood pressure were collected. Review Manager 5.2 and Stata 12.0 were used to perform the meta-analysis. Fixed and random effects models were applied to various aspects of the meta-analysis, which assessed the therapeutic effects of the two types of drug using the HOMA-IR index in non-diabetic patients. The meta-analysis included five clinical trials. Patient comparisons before and after treatment with ARBs and CCBs revealed that ARBs reduced the HOMA-IR index (weighted mean difference (WMD) -0.65, 95% confidence interval (CI) -0.93 to -0.38) and fasting plasma insulin (FPI) (WMD -2.01, 95% CI -3.27 to -0.74) significantly more than CCBs. No significant differences in the therapeutic effects of these two types of drug on blood pressure were observed. Given that there are no significant differences in the therapeutic effects of ARBs and CCBs on blood pressure, as ARBs are superior to CCBs in their effect on the HOMA-IR index in non-diabetics, they might be a better choice in hypertension patients without diabetes. © 2013.

    Full Text Available The aim of this study was to investigate the relationship between percentage of body fat (% BF and anthropometric indicators in individuals attending a gym. Four hundred and thirty eight individuals, 195 men and 243 women, from 18 to 50 years of age took part in this study. The % BF was estimated by the skinfold method. The following anthropometric indicators were assessed: waist circumference, abdomen circumference (AC, waist-to-hip ratio, body mass index (BMI and waist-height ratio. Linear Pearson correlation and simple linear regression analysis were used to investigate the relationship between variables. For women, BMI strongly correlated with % BF (r = .73, whereas for males, AC showed high correlation with % BF (r = .73. With varying degrees of magnitude, there were significant correlations between all of the anthropometric indicators analyzed and % BF.

    This cross-sectional study was carried out to capture possible maternal factors affecting newborns' anthropometric measurements. Data were collected from eight public health centres and referral university hospital records in Tabriz and Heriss districts, north-west Iran, for 807 mother-neonate pairs delivering live singleton births and their offspring during the two years up to August 2014. The incidence of low birth weight (LBW) was 5.1%. A close correlation was found between maternal anthropometry and birth order with neonatal anthropometric data. Birth order and maternal height and body mass index (BMI) positively affected neonates' birth size (weight, length and head circumference). The rate of LBW was significantly higher for older (≥35 years), taller (≥170 cm), underweight (BMIbirth neonates. The results indicate that maternal anthropometric indices, age, iron intake and birth order influence the risk of LBW in newborns.

    AIMS—To compare five anthropometric methods of classifying failure to thrive in order to ascertain their relative merits in predicting developmental, dietary, and eating problems.
METHODS—The five anthropometric methods were compared in 83 children with failure to thrive.
RESULTS—The methods were inconsistent in classification of severity, and no one method was superior in predicting problems.
CONCLUSIONS—Weight alone, being the simplest, is still the most reasonable marker for failure to thrive and associated problems.

    Malnutrition is one of the major contributors to child mortality in Ethiopia. Currently established, child nutrition status is assessed by four anthropometric indicators. However, there are other factors affecting children's anthropometric statuses. Thus, the main objective of this paper is to explore some of the determinants of child anthropometric indicators in Ethiopia. Data from GROW (the Growing Nutrition for Mothers and Children), a survey including 1261 mothers and 1261 children was carried out in Ethiopia in 2016. Based on the data gathered, the goal of GROW is to improve the nutritional status of women of reproductive age (15-49), as well as boys and girls under 5 years of age in Ethiopia. In order to investigate the association between different factors and child anthropometric indicators, this study employs various statistical methods, such as ANOVA, T-test, and linear regressions. Child's sex (confidence intervals for (wasting = - 0.782, - 0.151; stunting = - 0.936,-0.243) (underweight = - 0.530, - 0.008), child's age (confidence intervals for (wasting = - 0.020, 0.007; stunting = - 0.042,-0.011) (underweight = - 0.025, - 0.002), maternal MUAC (confidence intervals for (wasting = 0.189, 0.985; BMI-for-age = 0.077, 0.895), maternal education (stunting = 0.095, 0.897; underweight = 0.120, 0.729), and open defecation (stunting = 0.055, 0.332; underweight = 0.042, 0.257) were found to be significantly associated with anthropometric indicators. Contrary to some findings, maternal dietary diversity does not present significance in aforementioned child anthropometric indicators. Depending on the choice of children anthropometric indicator, different conclusions were drawn demonstrating the association between each factor to child nutritional status. Results showed child's sex, age, region, open defecation, and maternal MUAC significantly increases the risk of child anthropometric indicators

    Full Text Available Objective. To examine whether anthropometric measures could predict diabetes incidence in a Chinese population during a 15-year follow-up. Design and Methods. The data were collected in 1992 and then again in 2007 from the same group of 687 individuals. Waist circumference, body mass index, waist to hip ratio, and waist to height ratio were collected based on a standard protocol. To assess the effects of baseline anthropometric measures on the new onset of diabetes, Cox's proportional hazards regression models were used to estimate the hazard ratios of them, and the discriminatory power of anthropometric measures for diabetes was assessed by the area under the receiver operating curve (AROC. Results. Seventy-four individuals were diagnosed with diabetes during a 15-year follow-up period (incidence: 10.8%. These anthropometric measures also predicted future diabetes during a long follow-up (. At 7-8 years, the AROC of central obesity measures (WC, WHpR, WHtR were higher than that of general obesity measures (BMI (. But, there were no significant differences among the four anthropometric measurements at 15 years. Conclusions. These anthropometric measures could still predict diabetes with a long time follow-up. However, the validity of anthropometric measures to predict incident diabetes may change with time.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n1p31   High blood pressure is a leading cause of mortality worldwide and a risk factor for several diseases. The aim of this study was to determine the predictive power of anthropometric indicators of obesity and establish their cutoff points as discriminators of hypertension and identify the anthropometric indicator of obesity that best discriminates high blood pressure in the elderly. This is a cross-sectional study with a sample of 300 older adults, 167 (56.5% women. The following anthropometric indicators of obesity were measured: body mass index (BMI, waist circumference (WC, waist / height ratio (WHtR and conicity index. Moreover, systolic and diastolic blood pressure measurements were collected. To identify hypertension predictors, the analysis of receiver operating curves (ROC with 95% confidence interval was adopted. Subsequently, cutoff points with their respective sensitivities and specificities were identified. Analyses were carried out considering 5% significance level. It was observed that some anthropometric indicators of obesity showed area under the curve (AUC significant with BMI = 0.60 (0.50 to 0.70; WHtR = 0.61 (0.51 to 0.71; conicity index = 0.58 (0.58 to 0.68 in men. The different cutoff points of anthropometric indicators with better predictive power and their respective sensitivities and specificities were identified. The best areas under the ROC curve were for BMI, WHtR and conicity index for men; however, such measures were not satisfactory to predict high blood pressure in women.

    BACKGROUND: Calcium electroporation describes the use of high voltage electric pulses to introduce supraphysiological calcium concentrations into cells. This promising method is currently in clinical trial as an anti-cancer treatment. One very important issue is the relation between tumor cell kill...... efficacy-and normal cell sensitivity. METHODS: Using a 3D spheroid cell culture model we have tested the effect of calcium electroporation and electrochemotherapy using bleomycin on three different human cancer cell lines: a colorectal adenocarcinoma (HT29), a bladder transitional cell carcinoma (SW780......), and a breast adenocarcinoma (MDA-MB231), as well as on primary normal human dermal fibroblasts (HDF-n). RESULTS: The results showed a clear reduction in spheroid size in all three cancer cell spheroids three days after treatment with respectively calcium electroporation (p

    To assess the accuracy of body mass index (BMI), Z score of the BMI, waist circumference, and waist-to-height ratio in selecting obese children with fasting metabolic impairments or impaired glucose tolerance. In a cohort of 883 obese children and adolescents (age 8-18 years), we assessed the associations of anthropometric indices with traditional metabolic complications of obesity (impaired fasting glucose, impaired glucose tolerance, hypertension, high triglycerides, low high-density lipoprotein-cholesterol). The accuracy of anthropometric indices as markers of metabolic impairment was assessed by receiver operating characteristic analysis and the areas under the receiver operating characteristics curves (AUROCs) of anthropometric indices were compared with each other by the DeLong test. BMI, Z score of the BMI, waist circumference, and waist-to-height ratio were associated with metabolic impairments but showed low to moderate accuracy in discriminating both single and clustered metabolic impairments. The AUROCs ranged from 0.55-0.70. The 4 anthropometric indices did not show significantly different AUROCs as predictors of clustered metabolic risk factors (all P values of DeLong tests: >.05). Commonly used anthropometric indices are not satisfactory markers of metabolic comorbidity among obese children and adolescents and should not be adopted as screening tools for the metabolic assessment of this category of patients.

    (i) gender; (ii) performance and; (iii) gender versus performance interactions in young swimmers' anthropometric, kinematic and energetic variables. One hundred and thirty six young swimmers (62 boys: 12.76 ± 0.72 years old at Tanner stages 1-2 by self-evaluation; and 64 girls: 11.89 ± 0.93 years old at Tanner stages 1-2 by self-evaluation) were evaluated. Performance, anthropometrics, kinematics and energetic variables were selected. There was a non-significant gender effect on performance, body mass, height, arm span, trunk transverse surface area, stroke length, speed fluctuation, swimming velocity, propulsive efficiency, stroke index and critical velocity. A significant gender effect was found for foot surface area, hand surface area and stroke frequency. A significant sports level effect was verified for all variables, except for stroke frequency, speed fluctuation and propulsive efficiency. Overall, swimmers in quartile 1 (the ones with highest sports level) had higher anthropometric dimensions, better stroke mechanics and energetics. These traits decrease consistently throughout following quartiles up to the fourth one (i.e. swimmers with the lowest sports level). There was a non-significant interaction between gender and sports level for all variables. Our main conclusions were as follows: (i) there are non-significant differences in performance, anthropometrics, kinematics and energetics between boys and girls; (ii) swimmers with best performance are taller, have higher surface areas and better stroke mechanics; (iii) there are non-significant interactions between sports level and gender for anthropometrics, kinematics and energetics.

    Background: Growth abnormalities are uniquely associated with autism spectrum disorders (ASD); however, the extent to which growth abnormalities are present has hardly been investigated. The current study aims to compare the differences in anthropometric parameters in a group of autistic Egyptian children and the healthy normal population. Methods: We recruited 100 children with ASD from the Outpatient Clinic for "Autistic Children" at the Medical Research Hospital of Excellence, National Research Centre in Cairo, Egypt. They were diagnosed by DSM-IV criteria of the American Psychiatric Association, Autism Diagnostic Interview-Revised, and Childhood Autism Rating Scale. Of these children at age of 3-10 years, 71 were males and 29 females. Eight anthropometric parameters were assessed in view of data of the healthy Egyptians of pertinent sex and age. Results: Weight and body mass index increased because of a signifi cant increase in subcutaneous fat thickness. This tendency with a probable decrease in muscle mass was more evident in male or in older children, likely resulting from sedentary life style and food selectivity. Conclusions: The Z head circumference score and its variance signifi cantly increased especially in males or older children, suggesting the relative overgrowth of the brain in a substantial percentage of Egyptian children with autism. We concluded that increased fat composition in Egyptian autistic children with decreased muscle mass necessitates tailoring a specially designed food supplementation program to ameliorate the severity of autism symptoms.

    The effects of milk intake on bone health are not clear in elderly Asian men with low dietary calcium intake. This study showed that greater milk intake is associated with lower bone turnover, higher bone density, and higher bone microarchitecture index in community-dwelling elderly Japanese men. The consumption of milk or dairy products is widely recommended for maintaining bone health regardless of gender or age. However, little evidence exists on the beneficial effects of milk intake on bone health in elderly Japanese men characterized with relatively low dietary calcium intake. Here we examined whether or not greater milk intake was associated with lower bone turnover, higher bone density, and stronger bone microarchitecture in community-dwelling elderly Japanese men. Interviews were conducted to obtain information on medical history and lifestyle, including the amount of habitual milk intake, nutrient intake calculations based on a 1-week food diary, and measurements of areal bone mineral density (aBMD) at the lumbar spine (LS), total hip (TH), and femoral neck (FN) by dual-energy x-ray absorptiometry (DXA), trabecular bone score (TBS) using DXA images at LS, and biochemical markers of bone turnover in sera. Participants with a history of diseases or medications that affect bone metabolism, or with missing data, were excluded from the analysis. The median intake of milk in the 1479 participants (mean age, 73.0 ± 5.1 years) was one glass of milk per day. Bone turnover markers showed a decreasing trend (p turnover, higher aBMD, and higher TBS in community-dwelling elderly Japanese men.

    Full Text Available Objective: The aim of this study is to compare the predic­tive power of anthropometric indices for risk of developing Coronary Heart Disease (CHD or CHD death. Methods: We used cross-sectional data from nationally representative Chronic Diseases and Risk Factors Sur­vey conducted by the Ministry of Health in 2011. Body mass index (BMI, waist circumference (WC, waist-to-hip ratio (WHR, waist to height ratio (WHtR, body adiposity index (BAI and A Body Shape Index (ABSI formed the anthropometric measures. For each participant risk of de­veloping CHD or dying from CVDs were calculated based on Framingham and SCORE risk equations. Predictive ability of anthropometric measurements was assessed by receiver operating characteristic (ROC curves. Results: Anthropometric measurements of central obe­sity recorded higher area under the ROC curve (AUC values than BMI in both men and women. While ABSI had the highest AUC values for Framingham 10-year pre­dicted risk (FRS for CHD death (AUC = 0.613, SCORE 10-year risk for CVD death (AUC = 0.633, in women AUC for ABSI was the highest for only SCORE risk threshold (AUC = 0.705. Among women, WHtR was found to be the best indicator for estimating CHD incidence (AUC = 0.706 and death from CVD (AUC = 0.696. Conclusion: Compared to traditional anthropometric measurements such as BMI, ABSI was a better indicator for given thresholds for estimating the risk of developing CHD and CVD death in men. Among women WHtR made better predictions for FRS thresholds, however, ABSI was better for predicting 10-year risk of CVD death calculated by SCORE risk equation.

    Full Text Available Aims. Sleep disorders have recently become a significant public health problem worldwide and have deleterious health consequences. Obstructive sleep apnea (OSA is the most common type of sleep-related breathing disorders. We aimed to evaluate anthropometric measurements, glucose metabolism, and cortisol levels in patients with obstructive sleep apnea (OSA. Materials and Methods. A total of 50 patients with a body mass index ≥30 and major OSA symptoms were included in this study. Anthropometric measurements of the patients were recorded and blood samples were drawn for laboratory analysis. A 24-hour urine sample was also collected from each subject for measurement of 24-hour cortisol excretion. Patients were divided equally into 2 groups according to polysomnography results: control group with an apnea-hypopnea index (AHI <5 (n=25 and OSA group with an AHI ≥5 (n=25. Results. Neck and waist circumference, fasting plasma glucose, HbA1c, late-night serum cortisol, morning serum cortisol after 1 mg dexamethasone suppression test, and 24-hour urinary cortisol levels were significantly higher in OSA patients compared to control subjects. Newly diagnosed DM was more frequent in patients with OSA than control subjects (32% versus 8%, p=0.034. There was a significant positive correlation between AHI and neck circumference, glucose, and late-night serum cortisol. Conclusions. Our study indicates that increased waist and neck circumferences constitute a risk for OSA regardless of obesity status. In addition, OSA has adverse effects on endocrine function and glucose metabolism.

    Full Text Available The contactless automatic anthropometric system is proposed for the reconstruction of the 3D-model of the human body using the conventional smartphone. Our approach involves three main steps. The first step is the extraction of 12 anthropological features. Then we determine the most important features. Finally, we employ these features to build the 3D model of the human body and classify them according to gender and the commonly used sizes.

    An automated procedure for measuring and recording the anthropometric active angles is presented. The small portable system consists of a microprocessor controlled video data acquisition system which measures single plane active angles using television video techniques and provides the measured data on sponsored-specified preformatted data sheets. This system, using only a single video camera, observes the end limits of the movement of a pair of separated lamps and calculates the vector angle between the extreme positions.

    This review is focused on anthropometric and physiological characteristics of soccer players with a view to establishing their roles within talent detection, identification and development programmes. Top-class soccer players have to adapt to the physical demands of the game, which are multifactorial. Players may not need to have an extraordinary capacity within any of the areas of physical performance but must possess a reasonably high level within all areas. This explains why there are marked individual differences in anthropometric and physiological characteristics among top players. Various measurements have been used to evaluate specific aspects of the physical performance of both youth and adult soccer players. The positional role of a player is related to his or her physiological capacity. Thus, midfield players and full-backs have the highest maximal oxygen intakes ( > 60 ml x kg(-1) x min(-1)) and perform best in intermittent exercise tests. On the other hand, midfield players tend to have the lowest muscle strength. Although these distinctions are evident in adult and elite youth players, their existence must be interpreted circumspectly in talent identification and development programmes. A range of relevant anthropometric and physiological factors can be considered which are subject to strong genetic influences (e.g. stature and maximal oxygen intake) or are largely environmentally determined and susceptible to training effects. Consequently, fitness profiling can generate a useful database against which talented groups may be compared. No single method allows for a representative assessment of a player's physical capabilities for soccer. We conclude that anthropometric and physiological criteria do have a role as part of a holistic monitoring of talented young players.

  1. Anthropometric change: implications for office ergonomics.

    Well-designed office workspaces require good anthropometric data in order to accommodate variability in the worker population. The recent obesity epidemic carries with it a number of anthropometric changes that have significant impact on design. We examine anthropometric change among US civilians over the last 50 years, and then examine that change in a subset of the US population--the US military--as military data sets often have more ergonomic dimensions than civilian ones. The civilian mean stature increased throughout the period 1962 to 2006 for both males and females. However, the rate of increase in mean weight was considerably faster. As a result, the male obesity rate changed from 10.7% in 1962 to 31.3% in 2006. The female change for the same period was 15.8% to 33.2%. In the Army, the proportion of obesity increased from 3.6% to 20.9%, in males. In the absence of national US ergonomic data, we demonstrate one approach to tracking civilian change in these dimensions, applying military height/weight regression equations to the civilian population estimates. This approach is useful for population monitoring but is not suitable for establishing new design limits, as regression estimates likely underestimate the change at the ends of the distribution.

    Since its first publication in 2000, the BONN-Risk-Index (BRI) has been successfully used to determine the calcium oxalate (CaOx) crystallization risk from urine samples. To date, a BRI-measuring device, the "Urolizer", has been developed, operating automatically and requiring only a minimum of preparation. Two major objectives were pursued: determination of Urolizer precision, and determination of the influence of 24-h urine storage at moderate temperatures on BRI. 24-h urine samples from 52 CaOx stone-formers were collected. A total of 37 urine samples were used for the investigation of Urolizer precision by performing six independent BRI determinations in series. In total, 30 samples were taken for additional investigation of urine storability. Each sample was measured thrice: directly after collection, after 24-h storage at T=21 degrees C, and after 24-h cooling at T=4 degrees C. Outcomes were statistically tested for identity with regard to the immediately obtained results. Repeat measurements for evaluation of Urolizer precision revealed statistical identity of data (p-0.05). 24-h storage of urine at both tested temperatures did not significantly affect BRI (p-0.05). The pilot-run Urolizer shows high analytical reliability. The innovative analysis device may be especially suited for urologists specializing in urolithiasis treatment. The possibility for urine storage at moderate temperatures without loss of analysis quality further demonstrates the applicability of the BRI method.

    Full Text Available The benefits of dairy consumption seem to extend beyond its significant contribution to ensuring nutrient intake adequacy as indicated by the favourable associations with several health outcomes reported by different studies. The aims of the present study were to examine the associations of milk consumption with fitness, anthropometric and biochemical indices in children and further explore whether the observed associations are attributed to vitamins B2 and B12 derived from milk. A representative subsample of 600 children aged 9–13 years participating in the Healthy Growth Study was examined. Data were collected on children’s dietary intake, using 24 h recalls, as well as on fitness, anthropometric and biochemical indices. Regression analyses were performed for investigating the research hypothesis, adjusting for potential confounders and for B-vitamin status indices (i.e., plasma riboflavin, methylmalonic acid and total homocysteine concentrations, dietary calcium intake and plasma zinc concentrations that could possibly act as effect modifiers. Milk consumption was positively associated with the number of stages performed in the endurance run test (ERT (β = 0.10; p = 0.017 and negatively with body mass index (BMI (β = −0.10; p = 0.014, after adjusting for several potential confounders and effect modifiers. Dietary intakes of vitamin B2 and B12 derived from milk were also positively associated with the number of ERT stages (β = 0.10; p = 0.015 and β = 0.10; p = 0.014 respectively. In conclusion, higher intake of milk as well as vitamin B2 and B12 derived from milk were independently associated with higher cardiorespiratory fitness in Greek preadolescents. The key roles of these B-vitamins in substrate oxidation, energy production, haemoglobin synthesis and erythropoiesis could provide a basis for interpreting these associations. However, further research is needed to confirm this potential interpretation.

    To investigate which anthropometric adiposity measure has the strongest association with cardiovascular disease (CVD) risk factors in Caucasian men and women without a history of CVD. Systematic review and meta-analysis. We searched databases for studies reporting correlations between anthropometric adiposity measures and CVD risk factors in Caucasian subjects without a history of CVD. Body mass index (BMI), waist circumference, waist-to-hip ratio, waist-to-height ratio and body fat percentage were considered the anthropometric adiposity measures. Primary CVD risk factors were: systolic blood pressure, diastolic blood pressure, high density lipoprotein (HDL) cholesterol, triglycerides and fasting glucose. Two independent reviewers performed abstract, full text and data selection. Twenty articles were included describing 21,618 males and 24,139 females. Waist circumference had the strongest correlation with all CVD risk factors for both men and women, except for HDL and LDL in men. When comparing BMI with waist circumference, the latter showed significantly better correlations to CVD risk factors, except for diastolic blood pressure in women and HDL and total cholesterol in men. We recommend the use of waist circumference in clinical and research studies above other anthropometric adiposity measures, especially compared with BMI, when evaluating CVD risk factors.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2015v17n2p248   A model of an anthropometric record to be used in the Núcleos de Apoio à Saúde da Família (Centers for Family Health Support in Brazil has been proposed in the literature, showing the logistics of use. The aim of this study was to discuss the anthropometric record, showing the potential and obstacles of its use. It was observed that, for adults, the screening measures (body mass index and waist circumference for the determination of the risk of cardiovascular and metabolic diseases can be considered promising, although the Basic Health Care network already uses these measures. Nevertheless, the supplementary assessment (skinfold thickness and body circumferences could be another potential possibility, except for the time spent to perform this assessment and the lack of studies of the cost-benefit of these anthropometric techniques. It was concluded that the anthropometric record proposed is an important instrument for improving the quality of the service provided to users of the Basic Health Care System; however, some adjustments, such as the removal of skinfold measurements as part of primary care, should be taken into consideration.

    The objective of this study was to examine the association between physical and anthropometric profiles and vertical jump performance in elite volleyball players. Thirty-three elite male volleyball players (21±1 y, 76.9±5.2 kg, 186.5±5 cm) were studied. Several anthropometric measurements (body mass, stature, body mass index, lower limb length and sitting height) together with jumping height anaerobic power of counter movement jump with arm swing (CMJarm) were obtained from all subjects. Forward stepwise multiple linear regression analysis was performed to determine if any of the anthropometric parameters were predictive of CMJarm. Anaerobic power was significantly higher (P≤0.05) in the tallest players relative to their shorter counterparts. A significant relationship was observed between CMJarm and lower limb length (r2=0.69; P0.05) predictors of CMJarm performance. This study demonstrates that lower limb length is correlated with CMJarm in elite male volleyball players. The players with longer lower limbs have the better vertical jump performances and their anaerobic power is higher. These results could be of importance for trained athletes in sports relying on jumping performance, such as basketball, handball or volleyball. Thus, the measurement of anthropometric characteristics, such as stature and lower limb length may assist coaches in the early phases of talent identification in volleyball.

    To determine factors associated with pubertal gynecomastia. A cross-sectional study among healthy male school children and adolescents in Riyadh, Saudi Arabia. Subjects were selected from diverse socioeconomic backgrounds. Tanner stage, height, weight, blood hormonal levels (leutilizing hormone [LH], follicle-stimulating hormone [FSH], total testosterone, and estradiol), and anthropometric and lipid parameters (body mass index [BMI], triglycerides, high-density lipoprotein [HDL], and low-density lipoprotein [LDL]), were collected and compared in children with and without gynecomastia. The study included 542 children and adolescents. Median (interquartile range) age in the whole group was 11(8-13) years. The prevalence of gynecomastia was 185/542 (34%), with a peak at age 14. The 2 groups compared had nonsignificant difference in cholesterol (P=.331), LH (P=.215) and FSH (P=.571) levels. Those with gynecomastia were significantly older, had lower gonad stage, had higher anthropometric (height, weight, and BMI), and lipid (triglycerides, HDL, and LDL) values. In multivariate regression analysis, factors significantly associated with gynecomastia were BMI (odds ratio [OR]=1.05; 95%CI 1.00-1.10; P=.013), HDL (OR=0.42; 95%CI 0.19-0.92; P=.03), and gonad (Stage II OR=2.23; 95%CI 1.27-3.92; P=.005, Stage III OR=6.40; 95%CI 2.70-15.0; P gynecomastia tends to increase in mid-puberty. In our setting, BMI, HDL, and gonad stage were the major factors associated with the development of pubertal gynecomastia.

    Full text: Malnutrition, a condition marked by deficiencies of energy, protein, fats, vitamins and minerals, can pose a great risk to the health of a child. This paper aims to determine the nutritional status and the relationship between sociodemographic characteristics, nutrient and energy intake with anthropometric indicators among children below five years old. This study is part of the Nutrition Survey of Malaysian Children, which is part of the four-country South East Asian Nutrition Surveys (SEANUTS). This nationwide cross sectional study recruited a total of 880 (48.2% boys, 51.8% girls) children aged between 0.5 months to 5 years through stratified random sampling. Anthropometric measurements comprised weight and height, and body mass index (BMI) was calculated. Dietary intake was assessed by food frequency questionnaires developed and validated for Malaysian children. WHO Child Growth Standards 2006 was used to determine z-scores for height-for-age (HAZ), weight-for-age (WAZ), weight-for-height (WHZ) and BMI-for-age (BAZ). Overall, 7.5% of the children were underweight, 13.3% stunted, 3.2% wasted and 2.6% thin with the highest prevalence in children aged below one year. The prevalence of underweight (8.6% vs 6.3%), stunted (16.8% vs 9.7%) and wasting (4.0% vs 2.3%) was found to be higher among boys; while thinness was higher among girls (3.5% vs 1.6%). WHZ (R2 = 0.296), HAZ (R2 = 0.291) and BAZ (R2 = 0.265) were found to have positive and significant relationships with intake of energy, calcium and vitamin C. Statistically significant linear dependence of the mean of WAZ on all nutrient variables was found (R2 = 0.448). Other factors influencing anthropometric outcomes were sex, locality of residence, household income and ethnicity. In conclusion, malnutrition is still a health concern among children under five in Malaysia. Stunting and underweight is the predominant nutritional problem among children below one year old. Problems of malnutrition need to be

    Many foot pathologies are associated with specific foot types. If foot structure and function are related, measurement of either could assist with differential diagnosis of pedal pathologies. Biomechanical measures of foot structure and function are related in asymptomatic healthy individuals. Sixty-one healthy subjects' left feet were stratified into cavus (n=12), rectus (n=27) and planus (n=22) foot types. Foot structure was assessed by malleolar valgus index, arch height index, and arch height flexibility. Anthropometrics (height and weight), age, and walking speed were measured. Foot function was assessed by center of pressure excursion index, peak plantar pressure, maximum force, and gait pattern parameters. Foot structure and anthropometric variables were entered into stepwise linear regression models to identify predictors of function. Measures of foot structure and anthropometrics explained 10-37% of the model variance (adjusted R(2)) for gait pattern parameters. When walking speed was included, the adjusted R(2) increased to 45-77% but foot structure was no longer a factor. Foot structure and anthropometrics predicted 7-47% of the model variance for plantar pressure and 16-64% for maximum force parameters. All multivariate models were significant (pFoot structure and function are related in asymptomatic healthy individuals. The structural parameters employed are basic measurements that do not require ionizing radiation and could be used in a clinical setting. Further research is needed to identify additional predictive parameters (plantar soft tissue characteristics, skeletal alignment, and neuromuscular control) and to include individuals with pathology.

    Although fractional calcium absorption is known to vary inversely with calcium intake, the extent and timing of individual hormonal and calcium absorption responses to altered calcium intake have not been defined. We measured fractional whole body retention of orally ingested 47 Ca, an index of calcium absorption, in nine normal women after they had eaten a 2000-mg calcium diet for 8 weeks and a 300-mg calcium diet for 1, 2, 4, and 8 weeks. After the diet change, serum intact PTH (32.2% increase; P = 0.005), serum 1,25-dihydroxyvitamin D [1,25-(OH)2D; 43.8% increase; P = 0.003], and fractional whole body calcium retention (42.8% increase; P = 0.004) increased within 1 week. Although the PTH and calcium retention responses remained fairly constant throughout the low calcium intake period, serum 1,25-(OH)2D concentrations declined toward baseline after week 1. Thus, the late increase in calcium retention may have resulted from calcium absorption that was independent of 1,25-(OH)2D stimulation

    Anthropometric methods of measuring the whole body and body parts are the most commonly applied methods of analysing the growth and development of children. Anthropometric measures are interconnected, so that with growth and development the change of one of the parameters causes the change of the other. The aim of the paper was to analyse whether dental development follows the overall growth and development and what the ratio of this interdependence is. The research involved a sample of 134 participants, aged between 6 and 8 years. Dental age was determined as the average of the sum of existing permanent teeth from the participants aged 6, 7 and 8. With the aim of analysing physical growth and development, commonly accepted anthropometric indexes were applied: height, weight, circumference of the head, the chest cavity at its widest point, the upper arm, the abdomen, the thigh and thickness of the epidermis. The dimensions were measured according to the methodology of the International Biological Programme. The influence of the pertinent variables' related size on the analysed variable was deter mined by the statistical method of multivariable regression. The middle values of all the anthropometric parametres, except for the thickness of the epidermis, were slightly bigger with male participants, and the circumference of the chest cavity was statistically considerably bigger (p development. There is a considerable positive correlation (R = 0.59) between dental age and anthropometric parameters of general growth and development, which confirms that dental development follows the overall growth and development of children, aged between 6 and 8 years.

    Full Text Available Calcium is an important mineral playing a vital role to maintain bone health. Calcium intake is considered as one of the most important determinants to assess the calcium status and to evaluate the calcium deficiency in the human body. Our study aims at estimating calcium intake in a sample of children and adolescent to be used in the global strategy to reduce calcium deficiency disorders in Morocco. Thus, 131 children and adolescents were recruited from public schools at Rabat and its regions in the framework of a descriptive cross-sectional study. For each participant, anthropometric parameters were measured. Calcium status was assessed by 24 h dietary recall. Food frequency questionnaire was used to evaluate children’s nutritional habits and to assess the consumption of calcium-rich food. Overall, the mean calcium intake was 522.0 ± 297.0 mg/day, and 85.5% of subjects highlighted calcium deficiency, with no significant difference between boys and girls. Calcium intake was significantly different according to age groups, and high consumption of calcium was found in subjects aged from 14 to 18 years (776.86 ±290.07 mg/day, giving evidence of the low calcium status of the studied population. Daily food intake and food frequency analysis showed that bread, vegetables, and fruits are the most consumed food and the main source of daily calcium intake. Consumption of dairy products, considered as the best source of calcium, is lower and represents only 14% of total calcium intake. Our study clearly showed that calcium status is very lower in Moroccan children and adolescents and a large proportion of this population have inadequate calcium intake. Hence, there’s an urgent need of specific strategies, including children sensitisation and nutritional education, to increase calcium intake and therefore reduce calcium deficiency disorders impacting the whole body during childhood and in adult age.

    Women with higher serum calcium may be more likely to be diagnosed and die of ovarian cancer. We evaluated that finding in a large, prospective cohort. We conducted a nested case-control study using a population-based biobank from Norway. We compared 202 ovarian cancer cases and 202 controls, matched for age, date at blood draw, and county of residence, with respect to serum calcium and albumin, adjusted for anthropometric variables. We evaluated risks using the entire follow-up period as well as 2-15 years and 16-25 years ("early" and "late", respectively). For the entire follow-up, risk was significantly increased in the highest tertile of albumin and for high albumin and calcium jointly. Risks for ovarian cancer differed markedly by follow-up time. In early follow-up, women in the highest tertile of serum calcium had a 2.5-fold increased risk, adjusted for height and body mass index (OR=2.47, 95% C.I. 1.12-5.45) with a significant dose-response (p=0.024). Risk was not elevated in late follow-up (OR=0.62, 95% C.I. 0.27-1.36). Similarly, in early follow-up, women in the highest tertile of serum albumin had an increased risk (OR=2.55, 95% C.I.1.22-5.49) with a significant dose-response (p=0.009). Conversely, risk was not increased in late follow-up (OR=1.36, 95% C.I. 0.65-2.83). These data confirm a prospective association between higher serum calcium and ovarian cancer. An association in early, but not late, follow-up suggests that the higher calcium reflects the presence of existing cancer. A positive association with serum albumin is novel and should be interpreted cautiously. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Anthropometric measurements, such as the circumferences of the hip, arm, leg and waist, waist-to-hip ratio, and body mass index, are of high significance in obesity and fitness evaluation. In this paper, we present a home based imaging system capable of conducting anthropometric measurements. Body images are acquired at different angles using a home camera and a simple rotating disk. Advanced image processing algorithms are utilized for 3D body surface reconstruction. A coarse body shape model is first established from segmented body silhouettes. Then, this model is refined through an inter-image consistency maximization process based on an energy function. Our experimental results using both a mannequin surrogate and a real human body validate the feasibility of the proposed system.

    To evaluate and correlate anthropometric, biometric, and refractive error changes in thalassemia major (TM). One hundred children with TM and another hundred healthy controls were recruited. Height, weight, body mass index (BMI), and occipitofrontal circumference (OFC) were the anthropometric parameters recorded. Full ophthalmologic examination was performed, including best-corrected visual acuity, cycloplegic refraction, slit-lamp examination, Goldmann applanation tonometry, indirect ophthalmoscopy, keratometry (K readings), and ocular biometry. Compared to controls, children with TM were shorter and lighter, with a smaller BMI (pbiometric data, patients with thalassemia had steeper mean K readings (p = 0.03), shorter axial length (AXL) (p = 0.005), shorter vitreous chamber depth (pbiometric changes (steeper corneas and thicker lenses) to reach emmetropization, with an exaggerated response and subsequent myopic shift. However, growth retardation is not directly related to ocular growth changes, myopic shift, or variations in biometric parameters.

    Studies of two calcium transporting epithelia, embryonic chick chorioallantoic membrane and the small intestine of rat and chick, have strongly suggested that the transfer of calcium across a cell involves processes distinctly different from intracellular calcium ion regulation. In the proposed model, transcellular calcium transport is considered as a specialized process developed only by certain cells in those tissues charged with bulk transfer of calcium. The overall effect of the endocytotic mechanism is bulk calcium movement across a cell, protection of mitochondria from exposure to high concentrations of calcium, and the avoidance of wide and potentially toxic fluctuations in cytosol ionic calcium levels.

    Full Text Available Proponents of the efficient market hypothesis believe that active portfolio management is largely wasted effort and unlikely to justify the expenses incurred. Therefore, they advocate a passive investment strategy that makes no attempt to outsmart the market. One common strategy for passive management is indexing where a fund is designed to replicate the performance of a broad-based index of stocks and bonds. Traditionally, indexing was used by institutional investors, but today, the use of index funds proliferated among individual investors. Over the years, both international and domestic index funds have disproportionately outperformed the market more than the actively managed funds have.

    2014-01-01

    This study explored whether anthropometric measures influence magnitude of skin cooling following exposure to whole body cryotherapy (WBC). Height, weight, body fat percentage, and lean mass were measured in 18 male and 14 female participants. Body surface area, body surface area to mass ratio, body mass index, fat-free mass index, and fat mass index were calculated. Thermal images were captured before and after WBC (−60°C for 30 seconds, −110°C for 2 minutes). Skin temperature was measured at the chest, arm, thigh, and calf. Mean skin temperature before and after WBC and change in mean skin temperature (ΔT sk) were calculated. ΔT sk was significantly greater in females (12.07 ± 1.55°C) than males (10.12 ± 1.86°C; t(30) = −3.09, P = .004). A significant relationship was observed between body fat percentage and ΔT sk in the combined dataset (P = .002, r = .516) and between fat-free mass index and ΔT sk in males (P = .005, r = .622). No other significant associations were found. Skin response of individuals to WBC appears to depend upon anthropometric variables and sex, with individuals with a higher adiposity cooling more than thinner individuals. Effects of sex and anthompometrics should be considered when designing WBC research or treatment protocols. PMID:25061612

    The aim of this study was to assess food behavior, self-image perception and anthropometric indices of college students. This was a cross-sectional study with 54 students in a public university. The lifestyle and self-image perception was collected using a standardized questionnaire tested. Food behavior was evaluated through the Eating Attitudes Test. Body composition was assessed for Body Mass Index (BMI, circumferences, skinfold analysis and bioelectrical impedance (BIA. The statistics tests used were Chi-square and Pearson correlation (p< 0.05. The students had 19 to 27 years old, 96.3% were non-smokers, 46.3% drank alcoholic beverages and 37.0% practiced regular physical activity. Most of the students (75.5% were considered normal weight (BMI but the body fat percentage was found to be above average. Regarding self- image perception, 40.7% felt overweight. Observing food behavior results, 12.0% were at risk of developing eating disorders. Positive correlations were verifi ed between BMI with skinfold and skinfold with bioelectrical impedance. It was concluded that a considerable number of the college students assessed had a distorted self-image perception. Many of them had normal weight but with high body fat percentage. This study is relevant to investigate the risk of eating disorders and body image perception as part of the nutritional assessment.

    We analyzed the discriminatory capacity of anthropometric indicators for body fat in children and adolescents. This systematic review and meta-analysis included cross-sectional and clinical studies comprising children and adolescents aged 2-19 y that tested the discriminatory value for body fat measured by anthropometric methods or indexes generated by anthropometric variables compared with precision methods in the diagnosis of body fat [dual-energy X-ray absorptiometry (DXA), computed tomography, air displacement plethysmography (ADP), or MRI]. Five studies met the eligibility criteria and presented high methodologic quality. The anthropometric indicators that had high discriminatory power to identify high body fat were body mass index (BMI) in males [area under the curve (AUC): 0.975] and females (AUC: 0.947), waist circumference (WC) in males (AUC: 0.975) and females (AUC: 0.959), and the waist-to-height ratio (WTHR) in males (AUC: 0.897) and females (AUC: 0.914). BMI, WC, and WTHR can be used by health professionals to assess body fat in children and adolescents. © 2017 American Society for Nutrition.

    A large number of anthropometric studies of the auricle have been reported in different nations, but little data were available in the Chinese population. The aim of this study was to analyze growth changes in the ear by measuring the width and length of ears in a Chinese population. A total of 480 participants were enrolled and classified into 1-, 3-, 5-, 7-, 9-, 12-, 14-, and 18-year groups (half were boys and half were girls in each group). Ear length, ear width, body weight, and body length were measured and recorded; ear index was calculated according to ear length and ear width. The growth of auricle and differences between genders were analyzed. Growth of ear in relation to body height and weight and the degree of emphasis on the length and width of the auricle were also analyzed. Ear length and width increased with age. Ear length achieved its mature size in both 14-year-old males and females. Ear width reached its mature size in males at 7 years and in females at 5 years. Different trends of ear index were shown between males and females. People in this population paid more attention to the length than the width of the auricle. The data indicated that ear development followed increase in age. There were gender and ethnic difference in the development of ear. These results may have potential implications for the diagnosis of congenital malformations, syndromes, and planning of ear reconstruction surgery.

    King, C.W.; Nestor, O.H.

    1989-01-01

    A new process for producing large, single, oriented crystals of calcium fluoride (CaF 2 ) has been developed which overcomes the limitations of current growing methods. This process has been reduced to practice and has yielded oriented crystals 17.5 x 17.5 x 5 cm 3 . Currently nearing completion is a system for producing 35 x 35 x 7.5 cm 3 single crystals. A scale up to one-meter-square is considered feasible. This crystal growing process makes possible the fabrication of very large CaF 2 windows. Suitability for very high power lasers, however, requires attention to properties beyond mere size. A process to generate higher purity growth stock (starting material) was also developed. The additional purification of the growth stock contributes to lower bulk absorption, the absence of color centers and increased radiation hardness. Also identified were several specific impurities which correlate with radiation hardness. A correlation was found between color centers induced by laser radiation and ionizing radiation. Other CaF 2 crystal properties such as tensile strength, absorption and laser damage thresholds were studied and are discussed

    Prevalence of obesity in schizophrenic patients is two to three times higher than in the general population and unhealthy dietary patterns, a sedentary lifestyle and antipsychotic medication use may contribute to the higher levels of obesity among schizophrenic patients. We evaluated the effects of diet therapy on weight loss, anthropometric and biochemical variables in overweight or obese (body mass index, BMI ≥ 27 kg/m(2)) female schizophrenic patients who use antipsychotic medications and in healthy volunteers. Primary demographic variables were collected via questionnaire; blood samples and anthropometric measurements were obtained. Personalized diet recipes were prepared and nutritional education was shared. We logged the physical activity of the patients and maintained food consumption records at 3-day intervals. Participants were weighed every week; anthropometric measurements and blood samples were collected at the end of the first and second months. At the end of the study, reductions in body weight and other anthropometric measurements were statistically significant (P < 0.05). Reductions in body weight and BMI values for patient group were - 4.05 ± 1.73 kg and - 1.62 ± 0.73 kg/m(2) and for the control group were - 6.79 ± 1.80 kg and - 2.55 ± 0.64 kg/m(2), respectively. When compared with the patient group, reductions in the anthropometric variables of the control group were statistically significant (P < 0.05). Fasting glucose, blood lipids, albumin and leptin levels were decreased; insulin and homeostatic model assessment-measured insulin resistance (HOMA-IR) levels were increased insignificantly. Increases in the blood ghrelin levels for both groups were statistically significant (P < 0.05). Improvements to the diets of schizophrenic patient led to improvements in anthropometric measurements and biochemical variables and reduced the health risks caused by antipsychotic medications. Furthermore, we hypothesize that antipsychotic medications do not

    Large consortia have revealed hundreds of genetic loci associated with anthropometric traits, one trait at a time. We examined whether genetic variants affect body shape as a composite phenotype that is represented by a combination of anthropometric traits. We developed an approach that calculates averaged PCs (AvPCs) representing body shape derived from six anthropometric traits (body mass index, height, weight, waist and hip circumference, waist-to-hip ratio). The first four AvPCs explain >99% of the variability, are heritable, and associate with cardiometabolic outcomes. We performed genome-wide association analyses for each body shape composite phenotype across 65 studies and meta-analysed summary statistics. We identify six novel loci: LEMD2 and CD47 for AvPC1, RPS6KA5/C14orf159 and GANAB for AvPC3, and ARL15 and ANP32 for AvPC4. Our findings highlight the value of using multiple traits to define complex phenotypes for discovery, which are not captured by single-trait analyses, and may shed light onto new pathways.

    Background: The recommended anthropometric methods to assess the weight status include body mass index (BMI), skinfold thickness, and waist circumference. However, these methods have advantages and disadvantages regarding the classification of overweight and obesity in adolescents. Aims: The study was to analyze the correlation between the measurements of BMI, skinfold thickness and waist circumference to assess overweight and obesity in Portuguese adolescents. Materials and Methods: A sample of 966 students of Portugal was used. Of them, 437 (45.2%) were males and 529 (54.8%) were females aged between 10 and 16 years. The evaluations included BMI calculation, skinfold thickness, and waist circumference measurements. Results: This study revealed a high prevalence of overweight and obesity with values ranging from 31.6%, 61.4%, and 41.1% according to the measurement of BMI, skinfold thickness, and waist circumference, respectively. The results found a high level of correlation between BMI and skinfold thickness (P < 0.001, r = 0.712), between BMI and waist circumference (P < 0.001, r = 0.884), and waist circumference and skinfold thickness (P < 0.001, r = 0.701). Conclusions: This study revealed a high prevalence of overweight and obesity in Portuguese adolescents using three different anthropometric methods, where the BMI showed the lowest values of prevalence of overweight and obesity and the skinfold thickness showed the highest values. The three anthropometric methods were highly correlated. PMID:24404544

    Full Text Available Cardiovascular diseases are a growing public health problem that affects most people over the age of 65 years and abdominal obesity is one of the risk factors for the development of these diseases. There are several methods that can be used to measure body fat, but their accuracy needs to be evaluated, especially in specific populations such as the elderly. The aim of this study was to assess the accuracy of anthropometric indicators to estimate the percentage of abdominal fat in subjects aged 80 years or older. A total of 125 subjects ranging in age from 80 to 95 years (83.5 ± 3, including 79 women (82.4 ± 3years and 46 men (83.6 ± 3 years, were studied. The following anthropometric indicators were used: body mass index (BMI, waist circumference (WC, waist-hip ratio (WHR, and waist-to-height ratio (WHtR. The percentage of abdominal fat was measured by DEXA. Sensitivity and specificity were analyzed using an ROC curve. The sensitivity, specificity and AUC were 0. 578, 0. 934 and 0. 756 for BMI, respectively; 0.703, 0.820 and 0.761 for WC; 0.938, 0.213 and 0.575 for WHR, and 0.984, 0.344 and 0.664 for WHtR. BMI and WC were the anthropometric indicators with the largest area under the curve and were therefore more adequate to identify the presence or absence of abdominal obesity.

    Citrus juices such as 100% orange (OJ) and grapefruit juice (GJ) are commonly consumed throughout the world. This review examines the contributions of OJ and GJ to nutrient intake, diet quality, and fruit intake, and supports citrus juices as nutrient-dense beverages. This review also explores the research examining associations between OJ and GJ intake and anthropometric measures. Citrus juices are excellent sources of vitamin C and contribute other key nutrients such as potassium, folate, magnesium, and vitamin A. OJ intake has been associated with better diet quality in children and adults. OJ intake has not been associated with adverse effects on weight or other body measures in observational studies in children and adults. In adults, some observational studies report more favorable body mass index or body measure parameters in OJ consumers compared to nonconsumers. Intervention studies in adults report no negative impacts of OJ or GJ consumption on anthropometric measures, although these measures were typically not the primary outcomes examined in the studies. Moderate consumption of citrus juices may provide meaningful nutritional and dietary benefits and do not appear to negatively impact body weight, body composition, or other anthropometric measures in children and adults.

    Of the anthropometry and training variables used to predict race performance in a 24-hour ultrarun, the personal best marathon time is the strongest predictor in recreational male 24-hour ultramarathoners. This finding raises the question of whether similarities exist between male recreational 24-hour ultramarathoners and male recreational marathoners. The association between age, anthropometric variables (ie, body mass, body height, body mass index, percent body fat, skeletal muscle mass, limb circumference, and skinfold thickness at the pectoral, mid axillary, triceps, subscapular, abdominal, suprailiac, front thigh, and medial calf sites), previous experience and training characteristics (ie, volume, speed, and personal best time), and race time for 79 male recreational 24-hour ultramarathoners and 126 male recreational marathoners was investigated using bivariate and multivariate analysis. The 24-hour ultramarathoners were older (P marathoners. During training, the 24-hour ultramarathoners were running for more hours per week (P marathoners. In the 24-hour ultramarathoners, neither anthropometric nor training variables were associated with kilometers completed in the race (P > 0.05). In the marathoners, percent body fat (P marathon race times. In summary, differences in anthropometric and training predictor variables do exist between male recreational 24-hour ultramarathoners and male recreational marathoners for race performance.

    The present study aimed to assess serum leptin level in obese children to study its correlation with some metabolic variables as serum insulin and serum glucose. The study was conducted on 30 obese children of age from 9-14 years with body mass index (BMI) > 27.8 Kg/m 2 . All children were subjected to history taking, clinical examination, anthropometric measurements and laboratory investigations including fasting serum leptin, insulin and blood glucose. Serum leptin was significantly higher in obese children (102.3± 56.2 ng/ml) compared to non-obese ones (48.15±26.1 ng/ml). The relation between serum leptin and anthropometric measurements and laboratory investigations including fasting serum insulin and blood glucose. Serum leptin was significantly higher in obese children (102.3± 56.2 ng/ml)compared to non-obese ones (48.15±26.1 ng/ml). The relation between serum leptin and anthropometric variables was positively correlated with BMI r s = 0.68, (p s = 0.59.(p<0.01). It is concluded that serum leptin is increased in obesity and its concentration effects the size of the body. Moreover, the relation of leptin and insulin suggests a positive role of leptin in insulin resistance, which are common metabolic disorders associated with obesity

    The objective of this work was to compare the anthropometric and physical fitness characteristics of Brazilian adolescents who practise team court sports and to compare specific parameters obtained for adolescents with data from the general population. This was a cross-sectional study of 1,348 male adolescents grouped as follows: basketball players (n = 287), indoor soccer players (n = 665), handball players (n = 108) and volleyball players (n = 288), all between 10 and 14 years of age. Anthropometric (body mass, body height, arm span, and body mass index) and physical fitness data (flexibility, muscular strength, explosive power, speed, aerobic fitness and agility) were collected. The Brazilian population was used as a reference and compared to the adolescent subjects using Z scores for all variables. Anthropometric characteristics and performances in physical fitness tests differed (psports. In addition, for each variable assessed, adolescents who practised team court sports showed similar or improved results compared to their counterparts in the general population (pcharacteristics differed depending on the team court sport practised. These findings may elucidate which physical abilities are most impacted by the practise of a particular team sport as well as help teachers and physical education and sport professionals identify talented adolescents.

    To measure the abdominal subcutaneous fat (SF) and visceral fat (VF) volumes using high-field magnetic resonance imaging (MRI) and to investigate their association with selected anthropometric and biochemical parameters among obese and nonobese apparently healthy participants. A cross-sectional study was conducted by recruiting 167 healthy participants. Abdominal scans were acquired at 3T MRI, and the SF and VF were segmented and their volumes were calculated. Selected anthropometric and biochemical measurements were also determined. A significant difference (P abdominal fat volumes, leptin, resistin, adiponectin and waist circumference. Waist circumferences were measured by tape and MRI. Findings revealed that MRI-measured fat volumes were different between males and females and had a significant (P fat volumes were found to correlate moderately with interleukin-6 and weakly with cholesterol, serum triglyceride and low-density lipoprotein. Except for cholesterol, all measured biochemical variables and abdominal fat volumes in the current study were significantly associated with body mass index. All anthropometric and biochemical parameters showed weak-to-strong associations with the MRI-measured fat volumes. Abdominal fat distribution was different between males and females and their correlations with some lipid profiles were found to be sex dependent. These findings revealed that MRI can be used as an alternative tool for obesity assessment. Copyright © 2016 Southern Society for Clinical Investigation. Published by Elsevier Inc.

    Obesity is a multifactorial disease. This non-infectious epidemic has reached pandemic proportions in the 21 century. Posture is a dynamic process referring to an active maintenance of body movement segments against the action of external forces. The aim of the study was to investigate the effect of comprehensive group therapy for obese persons on selected anthropometric and postural parameters. The study comprised 53 females with a mean age of 44.5 years (range 29–65 years, standard deviation 9.42 years, median 44 years), who completed a controlled weight loss programme. At the beginning and at the end of the programme, anthropometric parameters (Body Mass Index (BMI), weight and waist circumference) were measured and the posturography tests Limits of Stability (LOS) and Motor Control Test (MCT) were performed using the NeuroCom's SMART EquiTest system. The data were statistically analyzed using R software at a level of significance of 0.05. There were positive changes after the controlled weight loss programme in anthropometric parameters (BMI reduction, with pobesity in terms of reductions in waist circumference, body weight and BMI, and thus the overall reduction of both cardiovascular and metabolic risks, as well as improved postural skills (activity and reactions).

    The purpose of this study was to analyze the relationships between 100-m front crawl swimming performance and relevant biomechanical, anthropometrical and physiological parameters in male adolescent swimmers. Twenty five male swimmers (mean ± SD: age 15. 2 ± 1.9 years; height 1.76 ± 0.09 m; body mass 63.3 ± 10.9 kg) performed an all-out 100-m front crawl swimming test in a 25-m pool. A respiratory snorkel and valve system with low hydrodynamic resistance was used to collect expired air. Oxygen uptake was measured breath-by-breath by a portable metabolic cart. Swimming velocity, stroke rate (SR), stroke length and stroke index (SI) were assessed during the test by time video analysis. Blood samples for lactate measurement were taken from the fingertip pre exercise and at the third and fifth minute of recovery to estimate net blood lactate accumulation (ΔLa). The energy cost of swimming was estimated from oxygen uptake and blood lactate energy equivalent values. Basic anthropometry included body height, body mass and arm span. Body composition parameters were measured using dual-energy X-ray absorptiometry (DXA). Results indicate that biomechanical factors (90.3%) explained most of 100-m front crawl swimming performance variability in these adolescent male swimmers, followed by anthropometrical (45.8%) and physiological (45.2%) parameters. SI was the best single predictor of performance, while arm span and ∆La were the best anthropometrical and physiological indicators, respectively. SI and SR alone explained 92.6% of the variance in competitive performance. These results confirm the importance of considering specific stroke technical parameters when predicting success in young swimmers. Key pointsThis study investigated the influence of different anthropometrical, physiological and biomechanical parameters on 100-m swimming performance in adolescent boys.Biomechanical factors contributed most to sprint swimming performance in these young male swimmers (90

    Full Text Available OBJECTIVE: The aim of the present study was to evaluate the influence of anthropometric characteristics and gender on postural balance in adults. One hundred individuals were examined (50 males, 50 females; age range 20-40 years. METHODS: The following body composition measurements were collected (using bone densitometry measurements: fat percentage (% fat, tissue (g, fat (g, lean mass (g, bone mineral content (g, and bone mineral density (g/cm2. In addition, the following anthropometric measurements were collected: body mass (kg, height (cm, length of the trunk-cephalic region (cm, length of the lower limbs (cm and length of the upper limbs (cm. The following indices were calculated: body mass index (kg/m², waist-hip ratio and the support base (cm². Also, a postural balance test was performed using posturography variables with open and closed eyes. RESULTS: The analysis revealed poor correlations between postural balance and the anthropometric variables. A multiple linear regression analysis demonstrated that the whole group (female and male height explained 12% of the medial-lateral displacement, 10% of the speed of oscillation, and 11% of the displacement area. The length of the trunk-cephalic length explained 6% of the displacement in the anteroposterior direction. With eyes closed, the support base and height explained 18% of the medial displacement, and the lateral height explained 10% of the displacement speed and 5% of the scroll area. CONCLUSION: Measured using posturography, the postural balance was only slightly influenced by the anthropometric variables, both with open and closed eyes. Height was the anthropometric variable that most influenced postural balance, both in the whole group and separately for each gender. Postural balance was more influenced by anthropometric factors in males than females.

    Full Text Available Background. Adolescence is one of the most challenging periods for human growth and nutritional status. The aim of this study was to assess the nutritional status and anthropometric indices in high school girls in Ilam. Methods. This cross-sectional study was performed on 360 domestic high school girl students chosen randomly by cluster sampling. Data were gathered through interviews performed by a dietitian to fill 24-hour dietary recall and food frequency and demographic questionnaires. Then we performed the anthropometric measurements and we compared the results with CDC2000 standards. We analyzed our data by N4 food analyzer and SPSS16 software. Results. The prevalence of obesity and overweight was 5% and 10.8%, respectively. Simultaneously, the prevalence of underweight was 20.2%. The prevalence of stunting was 5.8%. We also showed that 50% of high school girls in Ilam suffered from severe food insecurity, 14.7% suffered from mild insecurity, and 4.7% get extra energy from foods. Food analysis showed that micronutrients such as zinc, iron, calcium, folate, fiber, magnesium, and vitamin B12 were less than what is recommended by the RDA. Conclusion. Undernutrition and overnutrition are completely prevalent among girls studied in Ilam. This needs further acts and investigations in the field and more nutritional and health educations.

    Calcium oxide and calcium hafnium oxide thin films were grown by atomic layer deposition on borosilicate glass and silicon substrates in the temperature range of 205-300 o C. The calcium oxide films were grown from novel calcium cyclopentadienyl precursor and water. Calcium oxide films possessed refractive index 1.75-1.80. Calcium oxide films grown without Al 2 O 3 capping layer occurred hygroscopic and converted to Ca(OH) 2 after exposure to air. As-deposited CaO films were (200)-oriented. CaO covered with Al 2 O 3 capping layers contained relatively low amounts of hydrogen and re-oriented into (111) direction upon annealing at 900 o C. In order to examine the application of CaO in high-permittivity dielectric layers, mixtures of Ca and Hf oxides were grown by alternate CaO and HfO 2 growth cycles at 230 and 300 o C. HfCl 4 was used as a hafnium precursor. When grown at 230 o C, the films were amorphous with equal amounts of Ca and Hf constituents (15 at.%). These films crystallized upon annealing at 750 o C, showing X-ray diffraction peaks characteristic of hafnium-rich phases such as Ca 2 Hf 7 O 16 or Ca 6 Hf 19 O 44 . At 300 o C, the relative Ca content remained below 8 at.%. The crystallized phase well matched with rhombohedral Ca 2 Hf 7 O 16 . The dielectric films grown on Si(100) substrates possessed effective permittivity values in the range of 12.8-14.2

    Background and Aim: Cardiorespiratory fitness (CRF) is a useful tool for establishment of baseline fitness status and monitoring of physical activity level. Therefore, it may by extension serve as health risk index. However, studies that have determined the correlation between anthropometric indices and CRF in apparently healthy young adults is difficult to find in other to preempt preventive actions before pathology develops.

    Full Text Available Background: The increase in prevalence of coronary heart disease, type 2 diabetes, obesity and abnormal blood lipid levels has raised the question of a possible relationship between these conditions and the consumption of sugar. Objectives: This study investigated the sugar consumption of financially-restricted Black women in Mangaung, South Africa. Method: Five hundred women were selected randomly and divided into younger (25–34 years and older (35–44 years groups. Dietary intake, sociodemographic status, anthropometry and biochemical data were obtained. Total sugar (TS and added sugar (AS consumption were compared between older and younger women as well as sociodemographic, anthropometric and biochemical categories. Results: AS intake contributed 12% and 13% of total energy intake in younger and older women, respectively. AS consumption was higher in younger women living in brick houses and those who possessed a microwave oven. In older women, it was higher in husband-headed households. Underweight women with the lowest body mass index had higher sugar consumption than overweight and/or obese women. Women with a lower body fat percentage had a higher AS consumption than women with a high body fat percentage. Sugar consumption was significantly lower in younger women with elevated serum lymphocytecounts. TS and AS consumption was higher in younger women with elevated serum glucose levels. Older women with elevated serum insulin had a significantly higher TS consumption compared to those with normal insulin concentrations. Conclusion: The amounts of TS and AS consumed by women in this observational study were unlikely to contribute to overweight and/or obesity.

    Full Text Available Highly active antiretroviral therapy (HAART can cause side effects in HIV patients, as the metabolic syndrome. Early identification of risk for development of cardiovascular diseases using available reliable and practical methods is fundamental. On this basis, the aim of this study was to compare the effectiveness of anthropometric indicators to identify metabolic syndrome in HIV patients on HAART.It is a cross-sectional study. A number of 280 stable HIV patients were studied. It measured weight, height, waist circumference (WC, hip circumference (HP, thigh circumference (TC and calculated body mass index (BMI, body adiposity index (BAI, waist to hip ratio (WHR and waist to thigh ratio (WTR. There was also a performance of biochemical tests of lipid profile and fasting glucose. Systemic blood pressure was measured. The criteria proposed by the National Cholesterol Education Program III (NCEP-ATP III to metabolic syndrome classification was used. Individuals were divided in groups with or without metabolic alterations and their anthropometric indicators were compared. Receiver operating characteristic (ROC curves were designed for each anthropometric indicator using the metabolic syndrome classification to identify sensitivity and specificity.WC was a good tool to identify each metabolic disorder separately: total cholesterol (only females, p<0.05, triglycerides (only males, p<0.001, HDL cholesterol (p<0.05, LDL cholesterol (p<005 and fasting glycemic (p<005. WC also showed the best performance to identify metabolic syndrome in both genders (areas under the curve (AUCs: 0.79 and 0.76 for male and female, respectively, while BAI proved to be an inadequate indicator (AUCs: 0.63 and 0.67 for males and females, respectively, in this population.The central adiposity measure (WC had the best performance to identify metabolic syndrome, and it is a convenient, cheap and reliable tool that can be used in clinical practice routinely to prevent

    To know the prevalence of obesity in primary and secondary school students, and to evaluate the diagnostic accuracy of anthropometric variables for its detection. Cross-sectional study. Rural area of Córdoba. In the year 2014. Student population. A stratified sampling was performed according to age, gender and educational centers. A total of 323 students from 6 to 16 years were included in the study, all parents had signed informed consent. The prevalence of obesity was determined and sociodemographic, anthropometric, physical condition and dietary predictor variables were collected. A binary logistic regression was performed determining crude and adjusted Odds Ratio (OR) values, ROC curves were obtained and cut-off values were determined, calculating the sensitivity, specificity and Youden index. The prevalence of overweight and obesity was 26.2% and 22.3%, respectively. Only 15.2% of school children had an optimal Mediterranean diet. The waist-height ratio (WtHR) was the predictive variable with the highest adjusted OR 7.1 (4.3-11.6) and the largest area under the curve 0.954 (0.928-0.979), from a global cut-off value to discriminate obesity of 0.507. This gave a sensitivity of 90% and specificity of 87.2%. The high prevalence of obesity, the low-medium adherence to the Mediterranean diet and the low physical fitness make this population a priority target for the prevention of future cardiovascular events. The WtHR has been the best anthropometric predictor of obesity, recommending its use for the diagnosis of obesity in children at the expense of body mass index. Copyright © 2018 The Authors.

    Full Text Available Abstract Background The relationship between anthropometric indices and risk of basal cell carcinoma (BCC is largely unknown. We aimed to examine the association between anthropometric measures and development of BCC and to demonstrate whether adherence to World Health Organisation guidelines for body mass index, waist circumference, and waist/hip ratio was associated with risk of BCC, independent of sun exposure. Methods Study participants were participants in a community-based skin cancer prevention trial in Nambour, a town in southeast Queensland (latitude 26°S. In 1992, height, weight, and waist and hip circumferences were measured for all 1621 participants and weight was remeasured at the end of the trial in 1996. Prevalence proportion ratios were calculated using a log-binomial model to estimate the risk of BCC prior to or prevalent in 1992, while Poisson regression with robust error variances was used to estimate the relative risk of BCC during the follow-up period. Results At baseline, 94 participants had a current BCC, and 202 had a history of BCC. During the 5-year follow-up period, 179 participants developed one or more new BCCs. We found no significant association between any of the anthropometric measures or indices and risk of BCC after controlling for potential confounding factors including sun exposure. There was a suggestion that short-term weight gain may increase the risk of developing BCC for women only. Conclusion Adherence to World Health Organisation guidelines for body mass index, waist circumference and waist/hip ratio is not significantly associated with occurrence of basal cell carcinomas of the skin.

    To identify optimal anthropometric measures and cutoffs to identify undiagnosed diabetes mellitus (UDM) in three major Asian ethnic groups (Chinese, Malays, and Asian-Indians). Cross-sectional data were analyzed from 14,815 ethnic Chinese, Malay, and Asian-Indian participants of the Singapore National Health Surveys, which included anthropometric measures and an oral glucose tolerance test. Receiver operating characteristic curve analyses were used with calculation of the area under the curve (AUC) to evaluate the performance of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHTR) for the identification of UDM. BMI performed significantly worse (AUCMEN  = 0.70; AUCWOMEN  = 0.75) than abdominal measures, whereas WHTR (AUCMEN  = 0.76; AUCWOMEN  = 0.79) was among the best performing measures in both sexes and all ethnic groups. Anthropometric measures performed better in Chinese than in Asian-Indian participants for the identification of UDM. A WHTR cutoff of 0.52 appeared optimal with a sensitivity of 76% in men and 73% in women and a specificity of 63% in men and 70% in women. Although ethnic differences were observed in the performance of anthropometric measures for the identification of UDM, abdominal adiposity measures generally performed better than BMI, and WHTR performed best in all Asian ethnic groups. © 2016 The Obesity Society.

    Full Text Available We assessed whether dietary calcium intake or calcium supplements associated with body composition and obesity in a Chinese population.A cross-sectional survey was performed in a population of 8940, aged 20 to 74 y. 8127 participants responded (90.9%. Height, weight, fat mass (FM, waist circumference (WC and hip circumference were measured. Obesity definition: body mass index (BMI ≥28 kg/m(2 (overall obesity; WC ≥85 cm for men or ≥80 cm for women (abdominal obesity І and waist hip ratio (WHR ≥0.90 for men or ≥0.85 for women (abdominal obesity П. The data on dietary calcium and calcium supplements were collected using food-frequency questionnaire and self-report questionnaire. Multivariate linear and multivariable logistic regressions were used to examine the associations between dietary calcium intake or calcium supplements and body composition and obesity.The average dietary calcium intake of all subjects was 430 mg/d. After adjusting for potential confounding factors, among women only, negative associations were observed between habitual dietary calcium intake and four measures of body composition (β, -0.086, P0.05. Similarly, among both men and women, we did not observe significant associations between calcium supplements and any measures of body composition or abdominal obesity (P>0.05.Dietary calcium from food rather than elemental calcium from calcium supplements has beneficial effects on the maintenance of body composition and preventing abdominal obesity in Chinese women.

    Although the mechanism of calcium regulation is not understood, there is evidence that calcium plays a role in mitosis. Experiments conducted show that: (1) the spindle apparatus contains a highly developed membrane system that has many characteristics of sarcoplasmic reticulum of muscle; (2) this membrane system contains calcium; and (3) there are ionic fluxes occurring during mitosis which can be seen by a variety of fluorescence probes. Whether the process of mitosis can be modulated by experimentally modulating calcium is discussed.

    Full Text Available Introduction: Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. Objective: To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. Methods: A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years. Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. Results: The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone and PNS-P (distance between the posterior nasal spine and the tip of the soft palate and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years. Conclusion: Cephalometric measurements MP-H and PNS-P and cervical and waist circumfer- ences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group.

    The dimensions of the living and working space and buildings, the types of material and different riggings should be designed to conform to the users' anthropometric measures. The first requirement to design on ergonomic system is to measure the human being who will work and live in that system. Because of this, anthropometric measures are the most frequently used ergonomic data during the design process. In this research paper, we attempt to organize a new data base of anthropometric data to use in the design of children's equipment and furniture used in crèches. A starting point for research on the proper dimensions of creche furniture is to investigate how the dimensions of furniture reflect the body dimensions and the functional needs of the children using furniture. The anthropometric data of 3, 4 and 5 year-old-children in crèches was used. We report the results of the measurements of 18 anthropometric characteristics of children which constitute a set of basic data for the design of functional spaces and furniture.

    This study aimed to identify the physical and/or anthropometric qualities explanatory of adolescent surf lifesavers participating in paddling activities. Cross-sectional observational study. A total of 53 (14-18years) male participants were recruited and classified into two groups; paddlers (n=30; actively participating in paddling), non-paddlers (n=23; not actively participating in paddling). All participants completed a testing battery that consisted of 16 physical (isometric strength and muscular endurance) and anthropometric (height, mass, segment lengths and breadths) assessments. Binary logistic regression models and receiver operating characteristic curves were built to identify the physical and/or anthropometric qualities most explanatory of paddling status (two levels: 1=paddlers, 0=non-paddlers). Significant between group differences were noted for 14 of the 16 assessments (Ptalent detection programs focused toward the recognition of performance potential in paddling-oriented sports.

    Full Text Available Abstract    BACKGROUND: Obesity is increasing worldwide, but the debate about the most valid index associated with its health hazards remains unresolved. This study aimed to compare four main anthropometric indices by gender, to determine the best index in predicting cardiometabolic risk factors and to find their cutoff values in the population studied.    METHODS: This study was a cross-sectional community-based study performed on a representative sample of 12,514 adults (aged ≥19 years selected via 2-stage random cluster sampling from 3 cities in Iran. Partial correlation and ROC curve analyzes were used to determine the best anthropometric indices and their cutoff values.    RESULTS: The study population comprised 6123 males and 6391 females. In both genders, waist circumference (WC had the highest correlation with cardiometabolic risk factors (6 of 8 risk factors in men and 7 of 8 risk factors in women. ROC analyses showed that in males, the largest area under curve (AUC was obtained for waist-to-stature ration (WSR in most risk factors (6 of the 10 followed by body mass index (BMI and waist-to-height ratio (WHR with largest AUC (3 of the 10. The corresponding figure for females was obtained for WSR (9 of the 10 followed by BMI and WHR (1 of 10. Optimal cutoff values computed for combination of 3 major risk factors (including diabetes mellitus, hypertension and dyslipidemia revealed that in males and females, respectively, the cutoff values were 21.9 and 23.5 kg/m2 for BMI, 80.70 and 84.70 cm for WC, 0.85 and 0.86 for WHR and 0.47 and 0.53 for WSR.    CONCLUSION: WSR could be a valid anthropometric index for predicting cardiometabolic risk factors, and it has less variation than other indices among populations with ethnic differences in body size and fat distribution.      Keywords: Anthropometry, Cardiovascular Risk Factors, Iran, Obesity.

    Menopause results in metabolic changes that contribute to increase risk of cardiovascular diseases: increase in low density lipoprotein (LDL) and triglycerides and decrease in high density lipoprotein (HDL), weight gain are associated with a correspondent increase in incidence of hypertension and diabetes. The aim of this study was to evaluate the effect of a preparation of isoflavones, calcium vitamin D and inulin in menopausal women. We performed a prospective, randomized, placebo-controlled, parallel-group study. A total of 50 patients were randomized to receive either oral preparations of isoflavones (40 mg), calcium (500 mg) vitamin D (300 UI) and inulin (3 g) or placebo (control group). Pre- and post-treatment assessment of quality of life and sexual function were performed through Menopause-Specific Quality of Life Questionnaire (MENQOL) and Female Sexual Function Index (FSFI); evaluations of anthropometric indicators, body composition through bioelectrical impedance analyser, lumbar spine and proximal femur T-score and lipid profile were performed. After 12 months, a significant reduction in MENQOL vasomotor, physical and sexual domain scores ( p 0.05) were found in the same group. According to our data analysis, isoflavones, calcium, vitamin D and inulin may exert favourable effects on menopausal symptoms and signs.

    To evaluate the effect of tobacco smoking and salivary calcium on the periodontal status of young adults. Plaque index, gingival bleeding on probing, supragingival calculus, DMFT index, salivary flow, pH and salivary calcium in unstimulated salivary samples were recorded in smokers and nonsmokers. There were no significant differences between smokers and nonsmokers with respect to salivary flow (P = 0.08) and calcium level (P = 0.09). Significant correlations (P smoking of tobacco cigarettes in young healthy subjects may not have a significant impact on salivary flow or calcium concentrations in unstimulated saliva, but an association exists between an increased level of salivary calcium and development of periodontal disease.

    Defective absorption of calcium has been thought to exist in patients with achlorhydria. The author compared absorption of calcium in its carbonate form with that in a pH-adjusted citrate form in a group of 11 fasting patients with achlorhydria and in 9 fasting normal subjects. Fractional calcium absorption was measured by a modified double-isotope procedure with 0.25 g of calcium used as the carrier. Mean calcium absorption (+/- S.D.) in the patients with achlorhydria was 0.452 +/- 0.125 for citrate and 0.042 +/- 0.021 for carbonate (P less than 0.0001). Fractional calcium absorption in the normal subjects was 0.243 +/- 0.049 for citrate and 0.225 +/- 0.108 for carbonate (not significant). Absorption of calcium from carbonate in patients with achlorhydria was significantly lower than in the normal subjects and was lower than absorption from citrate in either group; absorption from citrate in those with achlorhydria was significantly higher than in the normal subjects, as well as higher than absorption from carbonate in either group. Administration of calcium carbonate as part of a normal breakfast resulted in completely normal absorption in the achlorhydric subjects. These results indicate that calcium absorption from carbonate is impaired in achlorhydria under fasting conditions. Since achlorhydria is common in older persons, calcium carbonate may not be the ideal dietary supplement

    Metformin is used in an attempt to reduce pregnancy complications associated with polycystic ovary syndrome (PCOS). Little is known about the effect of metformin on fetal development and growth. To compare the effect of metformin versus placebo on fetal growth and birth anthropometrics in PCOS offspring compared with a reference population in relation to maternal body mass index (BMI). Post hoc analysis of a randomized controlled trial. Double-blind, placebo-controlled, multicenter study. 258 offspring born to mothers with PCOS. 2000 mg metformin (n = 131) or placebo (n = 121) from first trimester to delivery. Mean abdominal diameter and biparietal diameter (BPD) at gestational weeks 19 and 32. Head circumference (HC), birth length, and weight related to a reference population of healthy offspring, expressed as gestational age- and sex-adjusted z-scores. Metformin- versus placebo-exposed offspring had larger heads at gestational week 32 (BPD, 86.1 mm versus 85.2 mm; P = 0.03) and at birth (HC, 35.6 cm versus 35.1 cm; P mothers. Among normal-weight mothers, the effect of metformin compared with placebo was reduced length (z-score = -0.96 versus -0.42, P = 0.04) and weight (z-score = -0.44 versus 0.02; P = 0.03). Compared with the reference population, offspring born to PCOS mothers (placebo group) had reduced length (z-score = -0.40; 95% confidence interval, -0.60 to -0.40), but similar birth weight and HC. Metformin exposure resulted in larger head size in offspring of overweight mothers, traceable already in utero. Maternal prepregnancy BMI modified the effect of metformin on offspring anthropometrics. Anthropometrics of offspring born to PCOS mothers differed from those of the reference population.

    Full Text Available Objectives. Body fat content, fat distribution, and adiponectin level are important variables in the development of obesity related complications. Anthropometric indices may provide an economic and faster method in measuring the risk for complications through their predictive effect of fat distribution and adiponectin concentration. We aimed to determine, which of the waist circumference (WC, waist-to-hip ratio (WHR, and body mass index (BMI may be the best predictor for the total fat percentage (WF, visceral fat level (VF, and subcutaneous whole-body fat (SCWBF. We aimed also to investigate the potential use of the anthropometric measures and fat distribution as predictors for the salivary adiponectin level in the healthy adult males. Subjects. A total of 88 adult males aged between 18−25 years with a wide range of BMI were studied. Anthropometric indices were measured using standardized methods and salivary adiponectin level was assessed using an enzyme-linked immunosorbent assay. Results. In path analysis of the Structural Equation Model (SEM using IBM@SPSS AMOS, version22, BMI and WC, but not WHR, were strong predictors for WF and SCWBF (p<0.05. BMI but not WC was a strong predictor for VF (p<0.001. WF was strong predictor for SCWBF (p<0.001, but not for VF. BMI, WC, WHR, WF, VF, and SCWBF were poor predictors of the salivary adiponectin level. Conclusion. BMI is the best predictor for the total body fat and fat distribution. However, WHR seems to be of a little value and the salivary adiponectin level independent of BMI and body fat in healthy adult Malay males.

    Anthropometric and lung function characteristics of triathletes are important for the implementation of individual specific training and recovery recommendations. However, limited data are available for these parameters in triathletes. Hence, the aim of this study was to characterize and examine the gender differences of lung function and anthropometry parameters in competitive triathletes from Malaysia. Body composition assessment and lung function tests were performed on sixteen competitive triathletes (nine male and seven female). The subject's body composition profile including muscle mass (kg), fat free mass (kg), and percent body fat was measured using a bio-impedance segmental body composition analyzer. Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured by Quark PFT2 spirometer. The anthropometric measurements revealed that male triathletes were significantly taller than female triathletes and had significantly more protein and skeletal muscle mass. The female triathletes, however, had significantly higher percent body fat. Male triathletes had statistically significant higher FVC and FEV1 than female triathletes. Both the male and female triathletes showed a positive correlation between height, fat free mass and the lung function markers FVC and FEV1. This association was not seen with Body Mass Index (BMI) in female triathletes. The data from our study shows that anthropometric parameters are directly linked to lung function of a triathlete. We also found the relationship between BMI and lung function to be gender specific in triathletes and is dependent on the body protein and fat content. Hence, body composition characterization is essential and provides valuable information for developing individual specific training modules.

    Full Text Available The purpose of this study was to analyze the relationships between 100-m front crawl swimming performance and relevant biomechanical, anthropometrical and physiological parameters in male adolescent swimmers. Twenty five male swimmers (mean ± SD: age 15. 2 ± 1.9 years; height 1.76 ± 0.09 m; body mass 63.3 ± 10.9 kg performed an all-out 100-m front crawl swimming test in a 25-m pool. A respiratory snorkel and valve system with low hydrodynamic resistance was used to collect expired air. Oxygen uptake was measured breath-by-breath by a portable metabolic cart. Swimming velocity, stroke rate (SR, stroke length and stroke index (SI were assessed during the test by time video analysis. Blood samples for lactate measurement were taken from the fingertip pre exercise and at the third and fifth minute of recovery to estimate net blood lactate accumulation (?La. The energy cost of swimming was estimated from oxygen uptake and blood lactate energy equivalent values. Basic anthropometry included body height, body mass and arm span. Body composition parameters were measured using dual-energy X-ray absorptiometry (DXA. Results indicate that biomechanical factors (90.3% explained most of 100-m front crawl swimming performance variability in these adolescent male swimmers, followed by anthropometrical (45.8% and physiological (45.2% parameters. SI was the best single predictor of performance, while arm span and ∆La were the best anthropometrical and physiological indicators, respectively. SI and SR alone explained 92.6% of the variance in competitive performance. These results confirm the importance of considering specific stroke technical parameters when predicting success in young swimmers.

    Full Text Available This study intended to take a biomechanical approach to understand the success of Kenyan distance runners. Anthropometric, gait and lower extremity strength characteristics of six elite Kenyan distance runners were analyzed. Stride frequency, relative stride length and ground contact time were measured at five running speeds (3.5 - 5.4 m/s using a motion capture system. Isometric knee extension and flexion torques were measured at six angles and hamstrings and quadriceps (H:Q ratios at three angular velocities were determined using an isokinetic dynamometer. These runners were characterized by a low body mass index (20.1 ± 1.8 kg·m- 2, low percentage body fat (5.1 ± 1.6% and small calf circumference (34.5 ± 2.3 cm. At all running speeds, the ground contact time was shorter (p < 0.05 during right (170 - 212 ms compared to left (177 - 220 ms foot contacts. No bilateral difference was observed in other gait or strength variables. Their maximal isometric strength was lower than other runners (knee extension: 1.4 - 2.6 Nm·kg-1, knee flexion: 1.0 - 1.4 Nm·kg-1 but their H:Q ratios were higher than athletes in other sports (1.03 ± 0.51 at 60o/s, 1.44 ± 0.46 at 120o/s, 1.59 ± 0.66 at 180o/s. The slim limbs of Kenyan distance runners may positively contribute to performance by having a low moment of inertia and thus requiring less muscular effort in leg swing. The short ground contact time observed may be related to good running economy since there is less time for the braking force to decelerate forward motion of the body. These runners displayed minor gait asymmetry, though the difference may be too small to be practically significant. Further investigations are needed to confirm whether the bilateral symmetry in strength and high H:Q ratios are related to genetics, training or the lack of injuries in these runners

    Full Text Available BackgroundMany studies have aimed to determine whether body mass index (BMI, waist circumference (WC, or waist to hip ratio (WHR best predicts hypertension in diabetic patients, with conflicting results. However, no study has examined the specific relationship between these anthropometric parameters with sustained normotension (SNT, white coat hypertension (WCHT, masked hypertension (MHT, and sustained hypertension (SHT based on office and ambulatory blood pressure (BP measurements in these patients.MethodsPatients with newly diagnosed type 2 diabetes underwent the following procedures: history taking, measurements of anthropometric parameters, office and ambulatory BP measurements, physical examination, laboratory analysis, and random and 24-hour urine analysis.ResultsIn total, there were 65 dippers and 37 nondipper patients. None of the anthropometric parameters were different between the dippers and the nondippers. There were 25 patients with SNT, 32 with WCHT, seven with MHT, and 38 with SHT. A comparison of anthropometric parameters between these four groups of patients showed that WC (P=0.016 and WHR (P=0.015 were different among all groups. According to regression analysis, only BMI was independently related with MHT (odds ratio [OR], 1.373, P=0.022, whereas only WC has been associated with SHT (OR, 1.321, P=0.041.ConclusionAmong anthropometric parameters, only WC and WHR were different in SNT, WCHT, MHT, and SHT in newly diagnosed patients with type 2 diabetes.

    Anthropometric data are a prerequisite for designing agricultural tools and equipment that enable workers to achieve better performance and productivity while providing better safety and comfort. A set of thirty anthropometric dimensions was collected from a total sample of 371 male and female farm-workers from three different regions (west, central and east) of Java Island, Indonesia. The mean stature is 162.0 cm and 152.5 cm, the sitting height is 82.9 cm and 77.4 cm, and the body weight is 57.1 kg and 52.3 kg for male and female subjects, respectively. The index of relative sitting height (RSH) was 0.51 on average for both male and female subjects. Significant differences are found in most of the anthropometric dimensions between gender and regional data groups as well. Compared with groups of people from several other countries, the anthropometric dimensions of Indonesian people are quite similar to Indian people, but are relatively smaller than Filipino, Chinese, Japanese, British, and American people. An attempt was conducted to illustrate the use of this anthropometric database and ergonomic considerations in refining the design of traditional tools and equipment commonly in use for rice farming operations.

    Full Text Available Background: Calcium channel blockers act at L-type calcium channels in cardiac and vascular smooth muscles by preventing calcium influx into cells with resultant decrease in vascular tone and cardiac inotropy, chronotropy and dromotropy. Poisoning with calcium channel blockers results in reduced cardiac output, bradycardia, atrioventricular block, hypotension and shock. The findings of hypotension and bradycardia should suggest poisoning with calcium channel blockers.Conclusions: Treatment includes immediate gastric lavage and whole-bowel irrigation in case of ingestion of sustainedrelease products. All patients should receive an activated charcoal orally. Specific treatment includes calcium, glucagone and insulin, which proved especially useful in shocked patients. Supportive care including the use of catecholamines is not always effective. In the setting of failure of pharmacological therapy transvenous pacing, balloon pump and cardiopulmonary by-pass may be necessary.

    2003-01-01

    The machinability of the plain carbon and low alloy structural steels with carbon content of 0.1-0.6% is briefly discussed in the first part of the paper. In the experimental part a dependence between the addition of calcium and some changes in sulphide and oxide inclusions morphology is presented. The Volvo test for measurement of machinability index B i has been applied. Using the multiple regression methods two relationships between machinability index B i and stereological parameters of non-metallic inclusions as well as hardness of the steels have been calculated. The authors have reached the conclusion that owing to the changes in inclusion chemical composition and geometry as result of calcium addition the machinability index of the steel can be higher.

    This paper is a report of a study conducted to evaluate the effects of behaviour modification on anthropometric indices and to explore if behaviour modification could improve eating behaviour in adolescents. Obesity is currently the most important nutritional disease of children and adolescents. To date, several attempts to achieve weight loss in children have been made, but little is known about their effects on improving eating behaviours. Sixty obese adolescent girls participated in a behaviour modification program which was held for 16 weeks in 2007. The participants were randomly selected from two different schools and were assigned to an experimental and control group (30 participants each). Anthropometric indices and eating behaviours were assessed before and after the program. Eating behaviour was assessed using the Dutch Eating Behaviour Questionnaire. There were statistically significant differences in changes in body weight (-2.75 kg vs. 0.62 kg), body mass index (-1.07 kg/m(2) vs. 0.24 kg/m(2)) and arm circumference (-2.31 cm vs. 0.5 cm) in the experimental group in contrast to controls (P behaviour, emotional eating (0.63, 0.17), external eating (0.99, 0.05) and restrained eating (0.72, 0.03) in the experimental vs. the control group respectively (P < 0.001). Nurses, more than other healthcare professionals, can address obesity in adolescents and they should not concentrate solely on weight reduction, but also encourage children to acquire a healthy lifestyle.

    This study evaluates possible differences in body dimensions among children from matings of different exogamy levels. The cross-sectional sample consisted of 867 children, 435 males, and 432 females, 6-10 years old, attending elementary schools in the metropolitan area of Cagliari, the capital of Sardinia (Italy). The children were divided into two groups according to the level of exogamy. The first group consisted of children of parents born in the same Sardinian municipality and was considered endogamous sensu stricto. The second group included children of parents born in municipalities from different Sardinian linguistic domains and was considered exogamous. The Mann-Whitney test did not reveal significant differences between the two groups of children in the mean rank values of the 36 anthropometric variables considered, with the exception of cephalic circumference in males and chest depth in females. In particular, there were no significant differences for anthropometric variables considered to be indirect indicators of nutritional status: sum of skinfolds, waist/hip ratio, body mass index, total upper arm area, upper arm muscle area, and upper arm fat area. The results indicate that Sardinian children from marriages of different exogamy levels do not differ in body dimensions if they grow up with similar nutritional and socioeconomic conditions.

Ergospirometry VO (2 max, Vertical Jump Test and the Wingate Test were used as functional indicators. Results: Regarding body composition, we found fat mass percentage 13.3 ± 3.2; muscle mass 47.3 ± 2.5%, and body adiposity index 24.1 ± 3.3. Somatotype profile was the mesomorphic-balanced (3.6-4.0-2.1. Mean values of functional tests with their standard deviations were: VO(2 máx (mL•kg-1•min-1 42.6 ± 8.1; anaerobic power 106.0 ± 31.8 kg•s-1, and anaerobic capacity 6501.0 ± 1831.6 K/jul. Conclusion: These results may provide a profile of long-distance runners that can be used as training targets for developing athletes. The results may also provide information for training and tactical emphasis.

    Full Text Available Excessive salt intake is known to increase blood pressure and cardiovascular risk. Nevertheless, salt intake exceeds the recommendations in most countries. To face this problem, it is important to identify high consumers as well as the main contributors of salt intake. Overall, data of 2018 adults between 18 and 64 years were analysed to determine the main sources, socio-demographic and anthropometric correlates of salt intake. Dietary intake was assessed from 24-h-recalls, information on socio-demographic characteristics was obtained using a questionnaire and anthropometric data were measured. Salt intake was significantly higher in males than in females. There was a significant positive association between salt intake and body mass index. No significant differences in salt intake were observed for other variables including affluence, educational level, smoking status and physical activity. The main contributor to salt intake were condiments including table salt (32.6%, followed by cereals and cereal products (27.0%, meat and meat products (16.1% and dairy products (14.0%. These results highlight that specific population groups need to be targeted by public health initiatives and that a reduction in salt intake can only be achieved in tandem with the food producers by the reduction of salt in processed foods.

    Previous investigations of strength have only focused on biomechanical or psychological determinants, while ignoring the potential interplay and relative contributions of these variables. The purpose of this study was to investigate the relative contributions of biomechanical, anthropometric, and psychological variables to the prediction of maximum parallel barbell back squat strength. Twenty-one college-aged participants (male = 14; female = 7; age = 23 ± 3 years) reported to the laboratory for two visits. The first visit consisted of anthropometric, psychometric, and parallel barbell back squat one-repetition maximum (1RM) testing. On the second visit, participants performed isometric dynamometry testing for the knee, hip, and spinal extensors in a sticking point position-specific manner. Multiple linear regression and correlations were used to investigate the combined and individual relationships between biomechanical, anthropometric, and psychological variables and squat 1RM. Multiple regression revealed only one statistically predictive determinant: fat free mass normalized to height (standardized estimate ± SE = 0.6 ± 0.3; t(16) = 2.28; p = 0.037). Correlation coefficients for individual variables and squat 1RM ranged from r = -0.79-0.83, with biomechanical, anthropometric, experiential, and sex predictors showing the strongest relationships, and psychological variables displaying the weakest relationships. These data suggest that back squat strength in a heterogeneous population is multifactorial and more related to physical rather than psychological variables.

  8. SELECTION OF TALENTS IN HANDBALL: ANTHROPOMETRIC AND PERFORMANCE ANALYSIS

    Full Text Available ABSTRACT Introduction: Anthropometric and physical performance parameters that determine competitive levels in handball need to be carefully studied to identify which of them can bring the optimal contribution when the talents for this sport are selected. Objective: To identify which anthropometric and physical performance variables evaluated in the basic categories (infantile, under-15 and cadet, under-17 have the greatest influence on professional levels attained by male and female handball players throughout their sports careers. Method: A total of 145 handball players (75 males and 70 females participated in the study. Participants were initially evaluated during the season 1998-99 and their performance levels were supervised until March 2013. The resulting data were classified according to the performance level (regional n = 109; national n = 36, gender, and category (infantile, cadet. Results: The MANCOVA analysis indicated that the player’s maturation stage is one of the main parameters to be accounted for when selecting the variables that should configure a talent detection model for handball, which is also conditioned by sex. Anthropometric variables are highly influential in the case of male players, while physical performance variables (squat jump, counter movement jump, counter movement jump with arm, 10x5m shuttle run, 20 m shuttle run, and VO2 max have a similar effect in males and females. Conclusion: The study of changes occurring in anthropometric and physical performance variables may yield useful information to detect talents in handball, and maturation is a key factor to choose the most appropriate variables.

    Facial anthropometric measurement is considered an essential concern of surgeons, orthodontists, artists and forensic scientists. The aim of this study is to investigate facial anthropometric norms of the young Iranian population. The study participants consisted of 200 healthy Iranian students (100 males, 100 females) aged 18-25 years old. Twenty-three liner and four angular measurements were investigated twice by a dentist. Independent-samples t test was used to compare indices between males and females and also between countries. A p value less than 0.05 was considered statistically significant. It was found that the mean measurements of c'-sn' of both sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were statistically greater in Iranian males than in females ( p  < 0.05). Comparing Iranian anthropometric norms with North American Whites, Malays, Turkish and African American women demonstrated that there were statistically significant differences in most anthropometric measurements between Iranians and other populations ( p  < 0.05). In Iranians, mean measurements of c'-sn' of the right and left sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were greater in men than in women. Comparing Iranian males and females with different ethnicities indicated several interracial differences, which should be taken into consideration when dealing with patients or also practitioners originated in this region.

    There are recent studies using new industrial workers' anthropometric data in different countries, but for Serbia such data are not available. This study is the first anthropometric study of Serbian metal industry workers in the country, whose labor force is increasingly employed both on local and international markets. The metal industry is one of Serbia's most important economic sectors. To this end, we collected the basic static anthropometric dimensions of 122 industrial workers and used principal components analysis (PCA) to obtain multivariate anthropometric models. To confirm the results, the dimensions of an additional 50 workers were collected. The PCA methodology was also compared with the percentile method. Comparing both data samples, we found that 96% of the participants are within the tolerance ellipsoid. According to this study, multivariate modeling covers a larger extent of the intended population proportion compared to percentiles. The results of this research are useful for the designers of metal industry workstations. This information can be used in dimensioning the workplace, thus increasing job satisfaction, reducing the risk of injuries and fatalities, and consequently increasing productivity and safety.

    Full Text Available Background: For understanding injuries in paediatric elbow and checking the degree of reduction after manipulation, various radiological criteria using anthropometric parameters are used. Since anthropometric parameters of Caucasians are different from European and Mongoloids, their parameters cannot be applied on our population. Hence, there is a need to characterise anthropometric parameters of elbow among children in the Indian population. Materials and Methods: The study population comprised all cases of injury to the elbow joint between 3 and 13 years of age reporting to the Department of Orthopaedics during the study. The X-rays films were preserved, and the angles and lines (as anthropometric parameters were drawn on the radiographs. Results: Mean ± (standard deviation [SD] for Baumann angle in children included in this study was 75° ± 4.70°. Mean ± (SD of Baumann angle in males was 76° ± 4.44° and females was 74° ± 5.37°. Mean ± (SD for lateral capitellohumeral angle in children from 3 to 13 years of age was 49 ± 5.75. Conclusions: As the values of normal side have been found to affect the functional and cosmetic outcome of the affected extremity, slight changes in values of our population in comparison to that of the Western population can significantly affect the outcome.

    To evaluate the relation between maternal prenatal hemoglobin concentration and neonatal anthropometric measurements. All pregnant women who gave birth at the Obstetrics Department of Dr. LK Kartal Training and Research Hospital, Istanbul, Turkey, from January 1, 2005 to December 31, 2006, and their newborns were included in this prospective, cross-sectional study. The newborns weight, height, head, and chest circumference were recorded. Mothers with hemoglobin concentration less than 11g/dl were evaluated as anemic. The anemic mothers were then grouped into 3 categories according to the corresponding hemoglobin concentration: mild (10.9-9.0g/dl), moderate (8.9-7.0 g/dl), and severe anemic (less than 7 g/dl). The anthropometric measurements of newborns from non-anemic and anemic mother groups were compared. Of the 3688 pregnant women, 1588 (43%) were found to be anemic. Among the anemic mothers, 1245 had mild (78.5%), 311 had moderate (19.5%), and 32 (2%) had severe anemia. The anthropometric measurements (height, weight, head and chest circumference) of newborns of anemic and non-anemic mother groups showed a statistically significant difference (p=0.036, p=0.044, p=0.013, and p=0.0002). There was a statistically significant difference in height, weight, and chest circumference of newborns of severe anemic and mild anemic mothers (p=0.017, p=0.008 and p=0.02). The height (1.1 cm), weight (260 g), head (0.42 cm), and chest (1 cm) circumference of neonates in the severe anemic group is less than the mild anemic group. Anemia during pregnancy affect the anthropometric measurements of a newborn. Severe anemia had significant negative effect on neonatal anthropometric measurements. (author)

    2008-01-01

    Calcium is one of the most important plasma constituents in mammals and birds. It provides structural strength and support (bones and eggshell) and plays vital roles in many of the biochemical reactions in the body. The control of calcium metabolism in birds is highly efficient and closely regulated in a number of tissues, primarily parathyroid gland, intestine, kidney, and bone. The hormones with the greatest involvement in calcium regulation in birds are parathyroid hormone, 1,25-dihydroxyvitamin D(3) (calcitriol), and estrogen, with calcitonin playing a minor and uncertain role. The special characteristics of calcium metabolism in birds, mainly associated with egg production, are discussed, along with common clinical disorders secondary to derangements in calcium homeostasis.

    2017-02-01

    Full Text Available Background: Substance abuse has significant impact on nutritional status. Due to the increased malnutrition during drug use and withdrawal, this study aimed at assessing the anthropometric indices in individuals referring to drug treatment centers in Qom. Methods: In this descriptive-analytical study, 329 addicted individuals referring to addiction centers in Qom were randomly selected. A questionnaire was used with three parts including demographic characteristics, drug abuse history, and anthropometric indices including measurement of height, weight, waist circumference, arm circumference, and skinfold thickness in triceps and calf muscles. Results: The participants consisted of 328 men and only one woman, 29% of whom were in detoxification. The participants' mean age was 39.0 ± 7.1 years. The first and most-frequently used drug was opium. All anthropometric indices were associated with the consumption of opium substances and drug use was associated significantly with some parameters. With the exception of skinfold thickness in the calf, all the indices were affected by the type of consumed substances. The opium addicts had a higher body mass index compared with other drug users. Conclusions: Due to the importance of nutrition status in drug abusers' health and their lack of self-care, careful monitoring and evaluation of dietary intake, as well as nutrition status can play important roles in the rehabilitation of these individuals and help to prevent from reappearance of these habits.

    Full Text Available The correlations between irisin levels, physical activity, and anthropometric measurements have been extensively described in adults with considerable controversy, but little evidence about these relationships has been found in children. The objective of this study is to correlate the plasma levels of irisin in underweight, normal weight, overweight, and obese children with anthropometric parameters and physical activity levels. A cross-sample of 40 children was divided into the following groups on the basis of body mass index (BMI percentile. The correlations of plasma irisin levels with physical activity, anthropometric, and metabolic measurements were determined. Plasma irisin levels (ng/mL were lower for the underweight group (164.2 ± 5.95 than for the normal weight and obese groups (182.8 ± 5.58; p<0.05. Irisin levels correlated positively with BMI percentile (0.387, waist circumference (0.373, and fat-free mass (0.353; p<0.05, but not with body muscle mass (−0.027. After a multiple linear regression analysis, only BMI percentile (0.564; p<0.008 showed a positive correlation with irisin. Our results indicated no association with metabolic parameters. A negative correlation with physical activity was observed. Interrelationships among body components might influence irisin levels in children.

    Resistin is a novel adipocyte-secreted hormone that has been proposed to be the link between obesity and diabetes, although little appears to be known regarding the physiological role of resistin in human beings. We aimed to explore the relationship between serum resistin level and certain anthropometric and metabolic parameters. Seventy-one healthy subjects with a mean body mass index of 23 kg/m 2 or greater were recruited in this study. Anthropometric measurements including height, weight, body mass index, waist and hip circumferences, waist-to-hip ratio, and blood pressure were recorded. Insulin resistance was measured by homeostasis model assessment (HOMA). Fasting serum resistin, insulin and plasma glucose, lipid profiles, and uric acid levels were measured. The results revealed that serum resistin level did not correlate with any markers for adiposity, blood pressure, fasting plasma glucose, or uric acid level for either sex. Serum resistin level correlated negatively with fasting insulin level (gamma=-0.455, P=.006) and HOMA (gamma=-0.455, P=.006) in women but not in men. Serum resistin level only correlated negatively with high-density lipoprotein cholesterol (HDL-C) level in men (gamma=-0.347, P=.038); there was no correlation between serum resistin level and lipid profiles in women. Multiple linear regression analysis using the logarithm of resistin as a dependent variable revealed that only HDL-C level (beta=-.058, P=.019) was an independent significant predictor for resistin in men; however, the analysis revealed that HDL-C level (beta=-.044, P=.029) and HOMA (beta=-.719, P=.004) were independent significant predictors for resistin in women. In conclusion, resistin is not related to adiposity, blood pressure, insulin resistance, fasting plasma glucose level, and most lipid profiles. Resistin correlates negatively with HDL-C level for both sexes. The role of resistin in metabolic syndrome warrants further investigation.

    Summary Introduction: Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) often have associated changes in craniofacial morphology and distribution of body fat, either alone or in combination. Aim: To correlate cephalometric and anthropometric measures with OSAHS severity by using the apnea-hypopnea index (AHI). Method: A retrospective cephalometry study of 93 patients with OSAHS was conducted from July 2010 to July 2012. The following measurements were evaluated: body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC), the angles formed by the cranial base and the maxilla (SNA) and the mandible (SNB), the difference between SNA and SNB (ANB), the distance from the mandibular plane to the hyoid bone (MP-H), the space between the base of the tongue and the posterior pharyngeal wall (PAS), and the distance between the posterior nasal spine and the tip of the uvula (PNS-P). Means, standard deviations, and Pearson's correlation coefficients were calculated and analyzed. Results: AHI correlated significantly with BMI (r = 0.207, p = 0.047), NC (r = 0.365, p = 0.000), WC (r = 0.337, p = 0.001), PNS-P (r = 0.282, p = 0.006), and MP-H (r = 0.235, p = 0.023). Conclusion: Anthropometric measurements (BMI, NC, and WC) and cephalometric measurements (MP-H and PNS-P) can be used as predictors of OSAHS severity. PMID:25992029

    The aim of this systematic review was to identify and summarize evidence of the association between anthropometric measurements and periodontal status in children and adolescents. We searched PubMed, Institute for Scientific Information Web of Knowledge, Cochrane Library, and 7 additional databases, following the guidance of Preferred Reporting Items for Systematic Reviews and Meta-Analyses, up to December 2014. Observational studies reporting data on the association between anthropometric measurements and periodontal diseases in 2-18-y-old participants were included. An initial search identified 4191 papers; 278 potentially effective studies (k = 0.82) and 16 effective studies (k = 0.83) were included after screening. The mean quality of evidence among the studies was 20.3, according to the Strengthening the Reporting of Observational studies in Epidemiology checklist (k = 0.79). Meta-analyses showed that obesity (measured by body mass index) was significantly associated with visible plaque index (OR: 4.75; 95% CI: 2.42, 9.34), bleeding on probing (OR: 5.41; 95% CI: 2.75, 10.63), subgingival calculus (OR: 3.07; 95% CI: 1.10, 8.62), probing depth (OR: 14.15; 95% CI: 5.10, 39.25) and flow rate of salivary secretion (standardized mean difference: -0.89; 95% CI: -1.18, -0.61). However, various results were reported in the effective studies that were not included in meta-analyses. In conclusion, obesity is associated with some signs of periodontal disease in children and adolescents. Further studies with a comprehensive prospective cohort design and more potential variables are recommended. © 2015 American Society for Nutrition.

    Since the space era began, we learned first to survive and then to live in space. In the state of the art, we know how important human factors research and development is to guarantee maximum safety and performance for human missions. With the extension of the duration of space missions, we also need to learn how habitability and comfort factors are closely related to safety and performance. Humanities disciplines such as design, architecture, anthropometry, and anthropology are now involved in mission design from the start. Actual plans for building a simulated Moon village in order to simulate and test Moon missions are now being carried out using a holistic approach, involving multidisciplinary experts cooperating concurrently with regard to the interactions among humans, technology, and the environment. However, in order to implement such plans, we need basic anthropometrical data, which is still missing. In other words: to optimize performance, we need to create doors and ceilings with dimensions that support a natural human movement in the reduced gravity environment of the Moon, but we are lacking detailed anthropometrical data on human movement on the Moon. In the Apollo missions more than 50 years ago, no anthropometrical studies were carried in hypogravity out as far as we know. The necessity to collect data is very consistent with state-of-the-art research. We still have little knowledge of how people will interact with the Moon environment. Specifically, it is not known exactly which posture, which kind of walking and running motions astronauts will use both inside and outside a Moon station.

     The purpose of this study was to examine relationships between lower body muscular strength, anthropometric characteristics and several measures of explosive performance in elite team-handball players.  22 male elite team-handball players (age: 19.1 ± 1.7 years) were studied during the competitive season. Standard anthropometric and body composition measures included body mass index, lower limb and thigh muscle volume, and body fat percentage. Maximal leg strength was determined by a one-repetition maximum (1-RM) half back-squat. Vertical jump performance was assessed using a squat jump (SJ) and a counter movement jump (CMJ). Repeated shuttle-sprint ability (RSA) was tested by 6 (2 × 15 m) shuttle sprints with 20 s of active recovery intervals. The best time in a single shuttle sprint (30m; RSA best ), fastest total time (RSA TT ) and RSA test performance decrement (RSA dec ) were recorded. Agility was measured using a modified T-half test (MAT). Throwing velocities of jump shooting and 3-step throwing were recorded by digital video camera.  The explained variance of 1-RM half-back-squats ranged from 0.2 % (RSA% Fatigue Index) to 70.1 % (CMJ). Four out of 8 variables (RSA Best Time, CMJ, SJ, throwing velocity of jump shoot) demonstrated an r 2  > 0.5. Jump performances seemed closely related to 1-RM half-back-squats. Furthermore, 1-RM half-back-squats were positively correlated with leg and thigh muscle volumes (r = 0.652, r = 0.768).  The anthropometric characteristics and some physical performance tests are closely related to the maximal strength performance of handball players. Coaches should focus on maximal strength training programs for the lower limbs when seeking improvements in the throwing velocity and jump performance of handball players. © Georg Thieme Verlag KG Stuttgart · New York.

    To characterise the nutritional status in children with obesity or wasting conditions, European anthropometric reference values for body composition measures beyond the body mass index (BMI) are needed. Differentiated assessment of body composition in children has long been hampered by the lack of appropriate references. The aim of our study is to provide percentiles for body composition indices in normal weight European children, based on the IDEFICS cohort (Identification and prevention of Dietary- and lifestyle-induced health Effects in Children and infantS). Overall 18,745 2.0-10.9-year-old children from eight countries participated in the study. Children classified as overweight/obese or underweight according to IOTF (N=5915) were excluded from the analysis. Anthropometric measurements (BMI (N=12 830); triceps, subscapular, fat mass and fat mass index (N=11,845-11,901); biceps, suprailiac skinfolds, sum of skinfolds calculated from skinfold thicknesses (N=8129-8205), neck circumference (N=12,241); waist circumference and waist-to-height ratio (N=12,381)) were analysed stratified by sex and smoothed 1st, 3rd, 10th, 25th, 50th, 75th, 90th, 97th and 99th percentile curves were calculated using GAMLSS. Percentile values of the most important anthropometric measures related to the degree of adiposity are depicted for European girls and boys. Age- and sex-specific differences were investigated for all measures. As an example, the 50th and 99th percentile values of waist circumference ranged from 50.7-59.2 cm and from 51.3-58.7 cm in 4.5- to <5.0-year-old girls and boys, respectively, to 60.6-74.5 cm in girls and to 59.9-76.7 cm in boys at the age of 10.5-10.9 years. The presented percentile curves may aid a differentiated assessment of total and abdominal adiposity in European children.

    The decrease in fat-free mass (FFM) seen in many elderly people is usually associated with an increase in fat mass (FM), a state referred to as sarcopenic obesity. It is not clear which anthropometric measures are best used to identify sarcopenic obesity. We therefore evaluated which anthropometric measures are differentially associated with FM and FFM. The anthropometric measures tested were body mass index (BMI), waist circumference (WC), and a body shape index (ABSI = WC/(BMI(2/3)*Height(1/2))). FM and FFM were estimated by dual-energy X-ray absorptiometry. An index-score was calculated for both FM (FMI) and FFM (FFMI) by dividing FM and FFM by height. Multivariable linear regression models were used to assess the associations of BMI, WC and ABSI with FMI and FFMI among 3612 participants (2092 women) from the prospective population-based Rotterdam Study. In multivariate models adjusted for confounders, BMI and WC were positively associated with both FMI and FFMI in men and women. ABSI was positively associated with FMI (β 1.01, 95% confidence interval (95%CI) 0.85, 1.17) and negatively associated with FFMI (β -0.28, 95%CI -0.38, -0.17) in men. In women, ABSI was not associated with FMI and was positively associated with FFMI (β 0.18, 95%CI 0.10, 0.26). While BMI and WC were both positively associated with FM and FFM, ABSI showed a differential association with FM and FFM in men, but not in women. Since sarcopenic obesity is associated with decreased FFM and increased FM, ABSI could be a useful tool for identifying men at higher risk of sarcopenic obesity.

    The objectives of this study were to determine whether the cross-sectional associations between anthropometric obesity measures, body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR), and calculated 10-year cardiovascular disease (CVD) risk using the Framingham and general CVD risk score models, are the same for women of Australian, UK and Ireland, North European, South European and Asian descent. This study would investigate which anthropometric obesity measure is most predictive at identifying women at increased CVD risk in each ethnic group. Cross-sectional data from the National Heart Foundation Risk Factor Prevalence Study. Population-based survey in Australia. 4354 women aged 20-69 years with no history of heart disease, diabetes or stroke. Most participants were of Australian, UK and Ireland, North European, South European or Asian descent (97%). Anthropometric obesity measures that demonstrated stronger predictive ability of identifying women at increased CVD risk and likelihood of being above the promulgated treatment thresholds of various risk score models. Central obesity measures, WC and WHR, were better predictors of cardiovascular risk. WHR reported a stronger predictive ability than WC and BMI in Caucasian women. In Northern European women, BMI was a better indicator of risk using the general CVD (10% threshold) and Framingham (20% threshold) risk score models. WC was the most predictive of cardiovascular risk among Asian women. Ethnicity should be incorporated into CVD assessment. The same anthropometric obesity measure cannot be used across all ethnic groups. Ethnic-specific CVD prevention and treatment strategies need to be further developed.

    Full Text Available Objective To assess the nutritional status of patients on maintenance hemodialysis by using modified quantitative subjective global assessment (MQSGA and anthropometric measurements. Method We Conducted a cross sectional descriptive analytical study to assess the nutritional status of fifty four patients with chronic kidney disease undergoing maintenance hemodialysis by using MQSGA and different anthropometric and laboratory measurements like body mass index (BMI, mid-arm circumference (MAC, mid-arm muscle circumference (MAMC, triceps skin fold (TSF and biceps skin fold (BSF, serum albumin, C-reactive protein (CRP and lipid profile in a government tertiary hospital at Kathmandu, Nepal. Results Based on MQSGA criteria, 66.7% of the patients suffered from mild to moderate malnutrition and 33.3% were well nourished. None of the patients were severely malnourished. CRP was positive in 56.3% patients. Serum albumin, MAC and BMI were (mean + SD 4.0 + 0.3 mg/dl, 22 + 2.6 cm and 19.6 ± 3.2 kg/m 2 respectively. MQSGA showed negative correlation with MAC ( r = −0.563; P = < 0.001, BMI ( r = −0.448; P = < 0.001, MAMC ( r = −0.506; P = < .0001, TSF ( r = −0.483; P = < .0002, and BSF ( r = −0.508; P = < 0.0001. Negative correlation of MQSGA was also found with total cholesterol, triglyceride, LDL cholesterol and HDL cholesterol without any statistical significance. Conclusion Mild to moderate malnutrition was found to be present in two thirds of the patients undergoing hemodialysis. Anthropometric measurements like BMI, MAC, MAMC, BSF and TSF were negatively correlated with MQSGA. Anthropometric and laboratory assessment tools could be used for nutritional assessment as they are relatively easier, cheaper and practical markers of nutritional status.

    Full Text Available The study was carried out to investigate the sexual dimorphism in length and other anthropometric parameters. To also generate formulae for height estimation using anthropometric measurements of some length parameters among Hausa ethnic group of Kaduna State, Nigeria. A cross sectional study was conducted and a total of 500 subjects participated in this study which was mainly secondary school students between the age ranges of 16-27 years, anthropometric measurements were obtained using standard protocols. It was observed that there was significant sexual dimorphism in all the parameters except for body mass index. In all the parameters males tend to have significantly (P < 0.05 higher mean values except biaxillary distances. Height showed positive and strongest correlations with demispan length, followed by knee height, thigh length, sitting height, hand length, foot length, humeral length, forearm length and weight respectively. There were weak and positive correlations between height and neck length as well as biaxillary length. The demi span length showed the strongest correlation coefficient and low standard error of estimate indicating the strong estimation ability than other parameters. The combination of two parameters tends to give better estimations and low standard error of estimates, so also combining the three parameters gives better estimations with a lower standard error of estimates. The better correlation coefficient was also observed with the double and triple parameters respectively. Male Hausa tend to have larger body proportion compared to female. Height showed positive and strongest correlations with demispan length. Body length anthropometric proved to be useful in estimation of stature among Hausa ethnic group of Kaduna state Nigeria.

    The primary study objective is to develop anthropometric data based upon the men and women who operate and maintain nuclear power plants. Age, stature, and weight information were obtained by a questionnaire survey of current operator and maintenance personnel, and the data extracted from the questionnaires were analyzed to derive body-size information for a number of anthropometric variables of interest to designers. Body-size information was developed separately for both men and women. Results achieved for the male population can be utilized by designers with a high level of confidence for the design of general workplaces. While the number of women respondents in the sample proved to be too small to derive results to which a similarly high level of reliability could be attached, the data can nevertheless be used as reasonable indicators of the probable body-size variability to be found among female power plant employees

    The Canadian Armed Forces (CAF) recently implemented the Fitness for Operational Requirements of CAF Employment (FORCE), a new physical employment standard (PES). Data collection throughout development included anthropometric profiles of the CAF. To determine if anthropometric measurements and demographic information would predict the performance outcomes of the FORCE and/or Common Military Task Fitness Evaluation (CMTFE). We conducted a secondary analysis of data from FORCE research. We obtained bioelectrical impedance and segmental analysis. Statistical analysis included correlation and linear regression analyses. Among the 668 study subjects, as predicted, any task requiring lifting, pulling or moving of an object was significantly and positively correlated (r > 0.67) to lean body mass (LBM) measurements. LBM correlated with stretcher carry (r = 0.78) and with lifting actions such as sand bag drag (r = 0.77), vehicle extrication (r = 0.71), sand bag fortification (r = 0.68) and sand bag lift time (r = -0.67). The difference between the correlation of dead mass (DM) with task performance compared with LBM was not statistically significant. DM and LBM can be used in a PES to predict success on military tasks such as casualty evacuation and manual material handling. However, there is no minimum LBM required to perform these tasks successfully. These data direct future research on how we should diversify research participants by anthropometrics, in addition to the traditional demographic variables of gender and age, to highlight potential important adverse impact with PES design. In addition, the results can be used to develop better training regimens to facilitate passing a PES. © All rights reserved. ‘The Influence of Anthropometrics on Physical Employment Standard Performance’ has been reproduced with the permission of DND, 2016.

    The purposes were to validate whether general motor abilities and anthropometrics are determinants of youth cross-country (XC) skiing performance; evaluate gender-specific differences; and to establish noninvasive diagnostics. Fifty-one youth XC skiers (34 boys; 13.8 ± 0.6 years and 17 girls; 13.4 ± 0.9 years) performed motor skill and laboratory tests, and anthropometric data were collected and correlated with XC skiing performance. Anthropometrics and maturity status were related to boys but not to girls XC skiing performance. Push-ups and 20-m sprint were correlated to XC skiing performance in both boys and girls. XC skiing performance of boys was predominantly influenced by upper body and trunk strength capacities (medicine ball throw, push-ups, and pull-ups) and jumping power (standing long and triple jump), whereas XC skiing of girls was mainly influenced by aerobic capacities (3000-m run). Laboratory measures did not reveal greater correlations to XC skiing performance compared with simple test concepts of speed, strength, and endurance. Maturity was a major confounding variable in boys but not girls. Use of noninvasive simple test concepts for determination of upper body strength, speed, and endurance represent practicable support for ski clubs, schools, or skiing federations in the guidance and evaluation of young talent, being aware of the effect of maturity especially in boys. © 2014 John Wiley & Sons A/S.

    2013-01-01

    Full Text Available Purpose: The purpose of this study was to find the correlation between vertical dimension of occlusion (VDO and length of fingers. Materials and Methods: A cross-sectional study was conducted on 400 dentate subjects comprising of 200 males and 200 females. Anthropometric measurements of VDO, length of index finger, length of little finger, and distance from tip of thumb to tip of index finger of right hand were recorded clinically using modified digital vernier caliper. Correlation between VDO and length of fingers was studied using Spearman′s coefficient. For the execution of regression command and preparation of prediction equations to estimate VDO, Statistical Package for Social Sciences Software Version 11.5 was used. Results: VDO was significantly and positively correlated with all the parameters studied. In males, correlation of VDO was strongest for length of index finger (r-0.406 whereas in females, it was strongest for length of little finger (r-0.385. VDO estimation using regression equation had a standard error of ± 3.76 in males and ± 2.86 in females for length of index finger, ±3.81 and ± 2.74 in males and females respectively for length of little finger, ±3.99 and ± 2.89 in males and females respectively for distance from tip of thumb to tip of index finger. Conclusions: Since the variations between VDO and finger lengths are within the range of 2-4 mm, VDO prediction through this method is reliable, and reproducible. Also the method is simple, economic, and non-invasive; hence, it could be recommended for everyday practice.

    2015-09-01

    Full Text Available Objective: To analyze the predictive capacity of anthropometric indicators and their cut-off values for dyslipidemia screening in children and adolescents. Methods: This was a cross-sectional study involving 1139 children and adolescents, of both sexes, aged 6–18 years. Body weight, height, waist circumference, subscapular, and triceps skinfold thickness were measured. The body mass index and waist-to-height ratio were calculated. Children and adolescents exhibiting at least one of the following lipid alterations were defined as having dyslipidemia: elevated total cholesterol, low high-density lipoprotein, elevated low-density lipoprotein, and high triglyceride concentration. A receiver operating characteristic curve was constructed and the area under the curve, sensitivity, and specificity was calculated for the parameters analyzed. Results: The prevalence of dyslipidemia was 62.1%. The waist-to-height ratio, waist circumference, subscapular, body mass index, and triceps skinfold thickness, in this order, presented the largest number of significant accuracies, ranging from 0.59 to 0.78. The associations of the anthropometric indicators with dyslipidemia were stronger among adolescents than among children. Significant differences between accuracies of the anthropometric indicators were only observed by the end of adolescence; the accuracy of waist-to-height ratio was higher than that of subscapular (p = 0.048 for females, and the accuracy of waist circumference was higher than that of subscapular (p = 0.029 and body mass index (p = 0.012 for males. In general, the cut-off values of the anthropometric predictors of dyslipidemia increased with age, except for waist-to-height ratio. Sensitivity and specificity varied substantially between anthropometric indicators, ranging from 75.6 to 53.5 and from 75.0 to 50.0, respectively. Conclusions: The anthropometric indicators studied had little utility as screening tools for dyslipidemia

    1978-01-01

    Dietary fibre from plants low in phytate bound calcium in proportion to its uronic-acid content. This binding by the non-cellulosic fraction of fibre reduces the availability of calcium for small-intestinal absorption, but the colonic microbial digestion of uronic acids liberates the calcium. Thus the ability to maintain calcium balance on high-fibre diets may depend on the adaptive capacity on the colon for calcium. (author)

  2. Walkability Index

    Science.gov (United States)

    The Walkability Index dataset characterizes every Census 2010 block group in the U.S. based on its relative walkability. Walkability depends upon characteristics of the built environment that influence the likelihood of walking being used as a mode of travel. The Walkability Index is based on the EPA's previous data product, the Smart Location Database (SLD). Block group data from the SLD was the only input into the Walkability Index, and consisted of four variables from the SLD weighted in a formula to create the new Walkability Index. This dataset shares the SLD's block group boundary definitions from Census 2010. The methodology describing the process of creating the Walkability Index can be found in the documents located at ftp://newftp.epa.gov/EPADataCommons/OP/WalkabilityIndex.zip.

    Protein-energy malnutrition is thought to be widespread in hospitalized patients. However, the specificity of indexes used to assess malnutrition is uncertain. We therefore assessed the rate of false-positive diagnoses of malnutrition when biochemical-anthropometric indexes were applied to healthy

    Full Text Available The conventional measurement of obesity utilises the body mass index (BMI criterion. Although there are benefits to this method, there is concern that not all individuals at risk of obesity-associated medical conditions are being identified. Whole-body fat percentage (%FM, and specifically visceral adipose tissue (VAT mass, are correlated with and potentially implicated in disease trajectories, but are not fully accounted for through BMI evaluation. The aims of this study were (a to compare five anthropometric predictors of %FM and VAT mass, and (b to explore new cut-points for the best of these predictors to improve the characterisation of obesity.BMI, waist circumference (WC, waist-to-hip ratio (WHR, waist-to-height ratio (WHtR and waist/height0.5 (WHT.5R were measured and calculated for 81 adults (40 women, 41 men; mean (SD age: 38.4 (17.5 years; 94% Caucasian. Total body dual energy X-ray absorptiometry with Corescan (GE Lunar iDXA, Encore version 15.0 was also performed to quantify %FM and VAT mass. Linear regression analysis, stratified by sex, was applied to predict both %FM and VAT mass for each anthropometric variable. Within each sex, we used information theoretic methods (Akaike Information Criterion; AIC to compare models. For the best anthropometric predictor, we derived tentative cut-points for classifying individuals as obese (>25% FM for men or >35% FM for women, or > highest tertile for VAT mass.The best predictor of both %FM and VAT mass in men and women was WHtR. Derived cut-points for predicting whole body obesity were 0.53 in men and 0.54 in women. The cut-point for predicting visceral obesity was 0.59 in both sexes.In the absence of more objective measures of central obesity and adiposity, WHtR is a suitable proxy measure in both women and men. The proposed DXA-%FM and VAT mass cut-offs require validation in larger studies, but offer potential for improvement of obesity characterisation and the identification of individuals

    Full Text Available Background: Ramadan is the fasting month among Muslims and the change in eating and sleep pattern can cause changes in human health. Objectives: This study was carried out to determine the effect of fasting in Ramadan on the anthropometric parameters and blood pressure level. Patients and Methods: This is a semi-experimental study conducted as before and after design on 93 staff of Shiraz University of Medical Sciences in 2014. The participants were selected through convenience sampling method. All the subjects were assessed for anthropometry parameters and blood pressure levels in two sections, before and after Ramadan. Data were presented as mean (SD or number (% for continuous or discrete variables, respectively. The data were analyzed via paired and independent t-test or Chi-square test. All the analyses were performed using the statistical Package for Social Sciences, version 17.0 (SPSS Inc., Chicago, IL, USA. P value less than 5% was considered significant. Results: All the subjects completed the study. In this study, 93 subjects with an age range of 25 - 57 years and mean of age 37.2 ± 7.9 years participated. Among them, 49 cases (52.7% were men. All the anthropometric parameters and blood pressure showed a significant difference; BMI: (26.1 ± 3.3 vs. 25.7 ± 3.2, P < 0.001, waist circumference: (89.1 ± 11.1 vs. 87.5 ± 11.1, P < 0.001, hip circumference: (101.4 ± 8.6 vs. 100.1 ± 8.5, P < 0.001, systolic blood pressure (101.7 ± 12.9 vs. 99.4 ± 12.7, P = 0.041, and diastolic blood pressure (72.3 ± 4.9 vs. 70.9 ± 5.3, P = 0.041. In addition, decrease in body mass index (P = 0.042 and weight (P = 0.03 were significantly greater in men. Conclusions: The data revealed that Ramadan can reduce anthropometric parameters and blood pressure levels. It was found that reduction in BMI and HC in men was significantly greater than women

This finding raises the question of whether similarities exist between male recreational 24-hour ultramarathoners and male recreational marathoners.Methods: The association between age, anthropometric variables (ie, body mass, body height, body mass index, percent body fat, skeletal muscle mass, limb circumference, and skinfold thickness at the pectoral, mid axillary, triceps, subscapular, abdominal, suprailiac, front thigh, and medial calf sites, previous experience and training characteristics (ie, volume, speed, and personal best time, and race time for 79 male recreational 24-hour ultramarathoners and 126 male recreational marathoners was investigated using bivariate and multivariate analysis.Results: The 24-hour ultramarathoners were older (P < 0.05, had a lower circumference at both the upper arm (P < 0.05 and thigh (P < 0.01, and a lower skinfold thickness at the pectoral, axillary, and suprailiac sites (P < 0.05 compared with the marathoners. During training, the 24-hour ultramarathoners were running for more hours per week (P < 0.001 and completed more kilometers (P < 0.001, but were running slower (P < 0.01 compared with the marathoners. In the 24-hour ultramarathoners, neither anthropometric nor training variables were associated with kilometers completed in the race (P > 0.05. In the marathoners, percent body fat (P < 0.001 and running speed during training (P < 0.0001 were related to marathon race times.Conclusion: In summary, differences in anthropometric and training predictor variables do

    Full Text Available The paper gives the review on the role of calcium in many physiological processes of plant organisms, including growth and development, protection from pathogenic influences, response to changing environmental factors, and many other aspects of plant physiology. Initial intake of calcium ions is carried out by Ca2+-channels of plasma membrane and they are further transported by the xylem owing to auxins’ attractive ability. The level of intake and selectivity of calcium transport to ove-ground parts of the plant is controlled by a symplast. Ca2+enters to the cytoplasm of endoderm cells through calcium channels on the cortical side of Kaspary bands, and is redistributed inside the stele by the symplast, with the use of Ca2+-АТPases and Ca2+/Н+-antiports. Owing to regulated expression and activity of these calcium transporters, calclum can be selectively delivered to the xylem. Important role in supporting calcium homeostasis is given to the vacuole which is the largest depo of calcium. Regulated quantity of calcium movement through the tonoplast is provided by a number of potential-, ligand-gated active transporters and channels, like Ca2+-ATPase and Ca2+/H+ exchanger. They are actively involved in the inactivation of the calcium signal by pumping Ca2+ to the depo of cells. Calcium ATPases are high affinity pumps that efficiently transfer calcium ions against the concentration gradient in their presence in the solution in nanomolar concentrations. Calcium exchangers are low affinity, high capacity Ca2+ transporters that are effectively transporting calcium after raising its concentration in the cell cytosol through the use of protons gradients. Maintaining constant concentration and participation in the response to stimuli of different types also involves EPR, plastids, mitochondria, and cell wall. Calcium binding proteins contain several conserved sequences that provide sensitivity to changes in the concentration of Ca2+ and when you

    Anthropometric and anaerobic profile of elite athletes are fundamental for the assessment of their respective performance. The present study was designed to evaluate the anthro- pornetric parameters, body composition and anaerobic characteristics of elite male handball players and rowers, and to compare them in relation to specific sport demands. The study group consisted of 41 elite national level athletes: 20 handball players (aged 23.7±3.72) and 21 rowers (aged 19.7±2.84). Anthropometric characteristics (body mass, body height, skinfold thickness, body circumferences), and body fat mass were evaluated, and Wingate anaerobic test for anaerobic power assessment Iwas applied. The significant differences were noted in chest-upper arm, waist and hip circumferences, and supraspinal and calf skinfolds between the two investigated groups. Rowers showed higher values of fat body mass (13.2±3.76 vs. 10.7±3.76%), but lower body mass index (22.0±1,92 vs. 25.7?2.31 kg/in12) compared to handball players. When analyzing the Wingate test parameters, significantly higher values of absolute anaerobic power (786±127 vs. 691±140 W), absolute explosive power in the handball players compared to the rowers were recorded ( 18±26.3 vs. 105±27.8 W/s), whi le rowers achieved higher relative anaerobic capacity (192±3 1.2 vs. 177±E20.8 J/ kg). Specific body composition and anthropometri- cal assessment as a part of morphological analysis should complement physiological profile of elite athletes. The analysis of the anaerobic performance shows that the handball players have greater alactic anaerobic and explosive power component, compared to the rowers in whom the anaerobic endurance and specific training have the greatest effect on the consumption of dominant metabolic substrate during the race.

    Full Text Available The aim of the study was to evaluate the effect of a short-term consumption (six weeks of gluten-free bakery products on the anthropometric parameters. The study group was composed of volunteers from the general population and consisted of 30 healthy adults. The amount of bakery product was determined as follows: women consumed 150 - 200 grams per day; men 200 - 250 grams per day. Anthropometric measurements were made by using InBody 720, we received data such as body weight, Body Mass Index (BMI and Waist-to-Hip Ratio (WHR, which we evaluated the presence of overweight and obesity in the monitored groups. We also observed visceral fat area (VFA. We found out that the 6-week consumption of gluten-free bread and bakery products showed a significant reduction in body weight and BMI (p <0.01, but also to a significant increase in VFA (p <0.05. By the impact of consumption we recorded the increase of body weight and BMI in 70% of participants (in 30% there was slight increase, decrease of WHR in 33% (increase in 43% and decrease of VFA in 43% (increase in 57%. For other participants, the values remained unchanged. Two months after the termination of the consumption of gluten-free products we found out the increase of body weight and BMI, WHR remained unchanged, however in the case of VFA showed significant increase of values. We can summarize that dietary habits play a crucial role in the development of overweight and obesity and the consumption of bread and bakery products can also affect it. However, the overall effect of bread and bakery consumption on the development of overweight depends on many factors, such as the composition of the bread and bakery products and the presence of gluten.

    Background Failure to thrive (FTT) in early childhood is associated with subsequent developmental delay and is recognised to reflect relative undernutrition. Although the concept of FTT is widely used, no consensus exists regarding a specific definition, and it is unclear to what extent different anthropometric definitions concur. Objective To compare the prevalence and concurrence of different anthropometric criteria for FTT and test the sensitivity and positive predictive values of these in detecting children with “significant undernutrition”, defined as the combination of slow conditional weight gain and low body mass index (BMI). Methods Seven criteria of FTT, including low weight for age, low BMI, low conditional weight gain and Waterlow's criterion for wasting, were applied to a birth cohort of 6090 Danish infants. The criteria were compared in two age groups: 2–6 and 6–11 months of life. Results 27% of infants met one or more criteria in at least one of the two age groups. The concurrence among the criteria was generally poor, with most children identified by only one criterion. Positive predictive values of different criteria ranged from 1% to 58%. Most single criteria identified either less than half the cases of significant undernutrition (found in 3%) or included far too many, thus having a low positive predictive value. Children with low weight for height tended to be relatively tall. Conclusions No single measurement on its own seems to be adequate for identifying nutritional growth delay. Further longitudinal population studies are needed to investigate the discriminating power of different criteria in detecting significant undernutrition and subsequent outcomes. PMID:16531456

    Full Text Available Childhood obesity is associated with a greater chance of a lifetime of obesity. Evidence suggests dairy at recommended levels could be beneficial in maintaining normal weight and body composition. We assessed whether dairy consumption is associated with anthropometric indicators of health (z-scores for weight-for-age (WAZ; height-for-age (HAZ and body mass index (BMIZ; waist-to-height ratio (WHtR; fat-free mass (FFM; and fat mass (FM in adolescents. In a cross-sectional study, 536 males and females ages 12–18 completed a 151-item semi-quantitative web-based food frequency questionnaire that included 34 dairy-containing foods. Dairy foods were categorized into milk, cheese, sweetened dairy, and total dairy. Anthropometrics were measured during school visits. Total dairy intake was associated with WAZ (β = 0.25 (95% CI: 0.01, 0.49, p = 0.045 and HAZ (β = 0.28 (95% CI: 0.04, 0.52, p = 0.021. In boys, total dairy was associated with WHtR (β = 0.02 (95% CI: 0.00, 0.04, p = 0.039, FFM (β = 4.83 (95% CI: 1.79, 7.87, p = 0.002, and FM (β = 3.89 (95% CI: 0.58, 7.21, p = 0.021, and cheese was associated with FFM (β = 4.22 (95% CI: 0.98, 7.47, p = 0.011. Dairy consumption seems to influence growth in both genders, and body composition and central obesity in boys. Prospective studies are needed to identify how types of dairy relate to growth, body composition, and central obesity of adolescents.

    Knowledge of patients' height is essential for daily practice in the intensive care unit. However, actual height measurements are unavailable on a daily routine in the ICU and measured height in the supine position and/or visual estimates may lack consistency. Clinicians do need simple and rapid methods to estimate the patients' height, especially in short height and/or obese patients. The objectives of the study were to evaluate several anthropometric formulas for height estimation on healthy volunteers and to test whether several of these estimates will help tidal volume setting in ICU patients. This was a prospective, observational study in a medical intensive care unit of a university hospital. During the first phase of the study, eight limb measurements were performed on 60 healthy volunteers and 18 height estimation formulas were tested. During the second phase, four height estimates were performed on 60 consecutive ICU patients under mechanical ventilation. In the 60 healthy volunteers, actual height was well correlated with the gold standard, measured height in the erect position. Correlation was low between actual and calculated height, using the hand's length and width, the index, or the foot equations. The Chumlea method and its simplified version, performed in the supine position, provided adequate estimates. In the 60 ICU patients, calculated height using the simplified Chumlea method was well correlated with measured height (r = 0.78; ∂ ventilation, alternative anthropometric methods to obtain patient's height based on lower leg and on forearm measurements could be useful to facilitate the application of protective mechanical ventilation in a Caucasian ICU population. The simplified Chumlea method is easy to achieve in a bed-ridden patient and provides accurate height estimates, with a low bias.

    Full Text Available Objective: Polycystic ovary syndrome (PCOS is the most common endocrine disorder among women of reproductive age.PCOS is considered to be not only a reproductive endocrinopathy, but also a metabolic disorder.The objective of the present study was to characterize the anthropometric and dietary profile of women with PCOS and to compare it with that of healthy age-matched women. Design: In this case-control study, 65 women with PCOS served as cases. The control group consisted of 65 age-matched healthy women. For each participant, demographic, anthropometric and dietary intake data were gathered and compared between the two groups. Results: There was no significant difference between the mean of the body mass index of the two groups, but the mean of waist circumference was significantly higher in the PCOS group, than the control group ( P = 0.016. Compared to the normal weight PCOS patients, a significantly higher percentage of overweight patients had hirsutism ( P = 0.009. In dietary analysis, women with PCOS consumed more calories and more fat than healthy women ( P = 0.001 and P = 0.019, respectively. Conclusion: It is concluded that in PCOS patients, android obesity is a common feature and this abdominal adiposity may be related to the syndrome′s complications. PCOS symptoms were more severe in overweight patients than the normal weight. Regarding the dietary pattern, it was indicated that patients with PCOS consume more calories and more fat in their diets and this might have been correlated to their disease.

Methods: a retrospective study of patients in labor and newborns from Hospital Santa Lucinda since 03/2009 to 02/2010: 19 of the study group (low weight and 50 of the control group (normal weight. The maternal variables included were: age, parity, puerperium; in the newborns were observed: sex, vitality, anthropometrics values, and outcomes. The statistical analysis involved the use Bioestat 5.0 program. Results: the middle perimeter head of newborns from low weight patients were 33,3 cm, and in the control group were 33,7 cm (p = 0,098; middle left arm perimeter were 10,0 cm and 10,3 cm (p = 0, 097; average weight: 2986,84 and 3165,32 g (p = 0, 0423, average length: 48,37 and 48, 77 cm (p = 0,2165 respectively. The average vitality from newborns after 1 and 5 minutes were: 8,1 - 8,1 (p = 0,9144 and 8,9 - 9,0 (p = 0,911. Conclusion: the weights of newborns from low weight patients in labor denote lower than normal weight patients. Low weight patients signify a risk group during the prenatal care, because there is more probability to be born low weight newborns. Prophylactics educating programs must be realized in order to avoid probable risks in low weight pregnant patients. Support PIBIC - CEPE

    Full Text Available Abstract Background Substantial evidence indicates that children’s physical fitness levels are markers of their lifestyles and their cardio-metabolic health profile and are predictors of the future risk of chronic diseases such as obesity, cardiometabolic disease, skeletal health and mental health. However, fitness reference values for ethnic children and adolescents have not been published in a Latin-American population. Therefore, the aim of the study was to provide sex- and age-specific physical fitness and anthropometric reference standards among Colombian-Indian schoolchildren. Methods A sample of 576 participants (319 boys and 257 girls aged 10 to 17 years old was assessed using the FUPRECOL test battery. Four components of physical fitness were measured: 1 morphological component: height, weight, body mass index (BMI, waist circumference (WC, triceps skinfold, subscapular skinfold, and body fat (%; 2 musculoskeletal component: handgrip and standing long jump test; 3 motor component: speed/agility test (4 × 10 m shuttle run; and 4 cardiorespiratory component: course-navette 20 m, shuttle run test and estimation of maximal oxygen consumption by VO2max indirect. Centile smoothed curves for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. Results Our results show that weight, height and BMI in each age group were higher in boys than in girls. In each groups, age showed a significant effect for BMI and WC. Boys showed better than girls in cardiorespiratory fitness, lower- and upper-limb strength and speed/agility and girls performed better in low back flexibility. Conclusion Our results provide for the first time sex- and age-specific physical fitness and anthropometric reference values for Colombian Nasa Indian children and adolescents aged 10–17.9 years.

    While diagnostic criteria for MS may vary depending on ethnicity, obesity remains a key risk factor in its development. In Taiwan, the incidence of obesity and MS among women has been increasing; however cut-off values for defining obesity for the diagnosis of MS among different groups of women have not been clearly established. The goal of this research was to examine the suitability of various anthropometric indicators of obesity in predicting the presence of MS criteria and to determine appropriate cut-off values of these indicators for women of different age and menstrual status. The sample was derived from the 2002 "Taiwan Three High Prevalence Survey" database. Women were divided into three groups based on age and menstrual status. Receiver-operating characteristic (ROC) curves was applied to the anthropometric indicators of obesity including, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), to ascertain its value in predicting MS. 2848 cases were included. It was found that most MS component values were worse with age and following menopause. Obesity indicators showed poor predictability for MS risks in post-menopausal women over 65 years, but good predictability in women under 65 years; our study revealed the following as ideal cut-off values for non-menopausal female: WHtRrisks in women over the age of 65, and cut-off values for obesity indicators need to be further reduced in non-menopausal women.

    2010-01-01

    Background Studies throughout North America and Europe have documented adverse perinatal outcomes for racial/ethnic minorities. Nonetheless, the contrast in newborn characteristics between indigenous and non-indigenous populations in Latin America has been poorly characterized. This is due to many challenges, including a lack of vital registration information on ethnicity. The objective of this study was to analyze trends in anthropometric measures at birth in Chilean indigenous (Mapuche) and non-indigenous children over a 5-year period. Methods We examined weight and length at birth using information available through a national data base of all birth records for the years 2000 through 2004 (n = 1,166.513). Newborns were classified ethnically according to the origins of the parents' last names. Result The average birthweight was stable over the 5 year period with variations of less than 20 g in each group, and with mean values trivially higher in indigenous newborns. The proportion weighing less than 2500 g at birth increased modestly from 5.2% to 5.6% in non-indigenous newborns whereas the indigenous births remained constant at 5.2%. In multiple regression analyses, adjusting flexibly for gestational age and maternal characteristics, the occurrence of an indigenous surname added only 14 g to an average infant's birthweight while holding other factors constant. Results for length at birth were similar, and adjusted time trend variation in both outcomes was trivially small after adjustment. Anthropometric indexes at birth in Chile are quite favorable by international standards. Conclusion There is only a trivial degree of ethnic disparity in these values, in contrast to conditions for ethnic minorities in other countries. Moreover, these values remained roughly constant over the 5 years of observation in this study. PMID:20598150

    To evaluate the nutritional status of mentally retarded children in the region of Galicia in north-west Spain, on the basis of anthropometric variables. The following variables were determined in a sample of 128 mentally retarded children (81 M, 47 F): birthweight, bodyweight, height/length, head circumference, mid-arm circumference, mid-arm muscle circumference, triceps skinfold thickness, subscapular skinfold thickness, arm area, arm muscle area, arm fat area, arm lean-to-fat ratio, Shukla's nutrition index and Quetelet's body mass index (BMI). A preliminary statistical analysis indicated that most information content could be maintained considering only eight of these variables. A factor analysis of the resulting 8 x 128 (variables by subjects) data matrix was performed, identifying two factors (FA1 and FA2) that together explained 82% of total variance. Taking these factors as indicators of nutritional status, the data were analysed for possible effects of age, gender, socioeconomic and family environment, intelligence quotient (IQ), presence/absence of cerebral palsy, quality of diet, appetite and antiepileptic use. The analysis suggested that most subjects were in the normal nutrition range, but about 33% showed either borderline or definite malnutrition. Mean score on FA2 showed a significant negative correlation with age. Children with cerebral palsy had lower mean scores on both factors, and scores on both factors varied with IQ. Children with definite malnutrition had a significantly lower IQ than those in the normal nutrition range. Mean score on both factors varied with appetite and quality of diet. The mean FAI score of children from inland-rural areas was significantly lower than that of children from coastal or urban areas. Mean FA1 score increased with increasing age of the parents. The prevalence of obesity was 13% when obesity was defined on the basis of Shukla's nutrition index, and 19% when defined on the basis of FA1 score. Malnutrition as

    Full Text Available Background: Undernutrition is a common cause of morbidity in children with CHD. Previous data from developing country showed prevalence of preoperative undernutrition in children with CHD was up to 45%. The aim of this study are to determine the anthropometric profiles and prevalence of undernutrition in children with CHD by using the anthropometric measurement.Methods: A cross-sectional study was carried out in children aged 0-2 years old with CHD in Cipto Mangunkusumo hospital. All patients underwent an anthropometric evaluation (weight, length and head circumference at presentation. Undernutrition, failure to thrive /FTT, short stature and microcephaly were determined according to WHO, weight-for-length, weight-for-age at 2 points, length-for-age, head circumference-for-age z-score < -2SD accordingly.Results: We had total of 95 patients, 73 patients with acyanotic and 22 patients with cyanotic lesions. Prevalence of undernutrition in CHD was 51.1%, with 22.3% severe undernutrition. FTT was found in 64.9%, short stature in 49.5% and microcephaly in  37% patients. FTT was found higher in acyanotic (72.2% compared to cyanotic lesions (42.9%. In acyanotic, weight was affected more than length (72.2% vs 49.3%. In cyanotic, weight and length affected equally (42.9% vs 54.5%. Diet counseling were done in patients with undernutrition. Medicines, transcatheter or surgery intervention were indicated in selected patients.Conclusions: Prevalence of FTT was higher than undernutrition in children with CHD. FTT was found higher in acyanotic lesions. In acyanotic, weight was affected more than length. In cyanotic, weight and length affected equally.

    Full Text Available The aim of this study was to evaluate the symmetry of anthropometry and muscle function in cross-country skiers and their association to vertical jumping power. Twenty cross-country skiers were recruited (21.7 ± 3.8 yrs, 180.6 ± 7.6 cm, 73.2 ± 7.6 kg. Anthropometric data was obtained using an iDXA scan. VO2max was determined using the diagonal stride technique on a ski treadmill. Bilateral functional tests for the upper and lower body were the handgrip and standing heel-rise tests. Vertical jump height and power were assessed with a counter movement jump. Percent asymmetry was calculated using a symmetry index and four absolute symmetry index levels. At a group level the upper body was more asymmetrical with regard to lean muscle mass (p = 0.022, d = 0.17 and functional strength (p = 0.019, d = 0.51 than the lower body. At an individual level the expected frequencies for absolute symmetry level indexes showed the largest deviation from zero for the heel-rise test (χ2 = 16.97, p = 0.001, while the leg lean mass deviated the least (χ2 = 0.42, p = 0.517. No relationships were observed between absolute symmetry level indexes of the lower body and counter movement jump performance (p > 0.05. As a group the skiers display a more asymmetrical upper body than lower body regarding muscle mass and strength. Interestingly at the individual level, despite symmetrical lean leg muscle mass the heel-rise test showed the largest asymmetry. This finding indicates a mismatch in muscle function for the lower body.

    Full Text Available Anthropometry is a science of human body measurement that could be used for manufacturing artificial limbs or prosthesis, investigating body differences between populations, utilizing in forensics and criminology, or even in the diagnosis of some diseases. Two of the most important anthropometric characteristics are dermatoglyphic patterns and finger length. Many studies have evaluated the relation between these two characteristics in different diseases such as cancers. It assumed that dermatoglyphic patterns and finger length could be used as predictors of some cancers such as gastric, ovarian, prostate, testicular, and breast cancers. In this review, we evaluated the relation between dermatoglyphic variability and finger length in different cancers more precisely.

    The identification of obesity as a pathological diagnosis depends on an accurate assessment of body fatness and a correlation of fatness with pathological consequences. Because total body fat varies with body weight, the proportion of body weight that is fat is probably a more reliable indicator of risk. Among obese children and adolescents, several problems have hindered the development of accurate clinical measures of percent body fat and total body fat. First, the use of direct methods to measure body composition is limited by expense and labor. Second, the relationship between anthropometric indexes and body composition in obese children and adolescents has not been intensively studied. Third, sample sizes of normal weight children have been too small to permit the development of diagnostic criteria. Fourth, the triceps skinfold is less reproducible in overweight subjects. Increases in lean body mass in obese adolescents may confound the use of the body mass index as a measure of adiposity. Current laboratory methods for the measurement of body composition include: (1) underwater weighing, (2) 40K counting, (3) isotopic dilution measures, (4) neutron activation, and (5) electrical impedance. This article examines relationships between those methods and anthropometry in the measurement of fatness in children and adolescents, as well as the difficulties in measuring body fatness and the importance of body fat distribution and its relationship to morbidity in children. Current evidence suggests an association of morbidity and upper segment obesity in adults. Corresponding studies in children and adolescents are yet to be carried out.

    Vertical jump is an index representing leg/kick power. The explosive movement of the kick is the key to scoring in martial arts competitions. It is important to determine factors that influence the vertical jump to help athletes improve their leg power. The objective of the present study is to identify anthropometric factors that influence vertical jump height for male and female martial arts athletes. Twenty-nine male and 25 female athletes participated in this study. Participants were Malaysian undergraduate students whose ages ranged from 18 to 24 years old. Their heights were measured using a stadiometer. The subjects were weighted using digital scale. Body mass index was calculated by kg/m(2). Waist-hip ratio was measured from the ratio of waist to hip circumferences. Body fat % was obtained from the sum of four skinfold thickness using Harpenden callipers. The highest vertical jump from a stationary standing position was recorded. The maximum grip was recorded using a dynamometer. For standing back strength, the maximum pull upwards using a handle bar was recorded. Multiple linear regression was used to obtain the relationship between vertical jump height and explanatory variables with gender effect. Body fat % has a significant negative relationship with vertical jump height (P martial arts athletes can be predicted by body fat %. The vertical jump for male is higher than for their female counterparts. Reducing body fat by proper dietary planning will help to improve leg power.

    Participation in endurance running such as half-marathon (21-km) and marathon (42-km) has increased over the last decades. We compared 147 recreational male half-marathoners and 126 recreational male marathoners to investigate similarities or differences in their anthropometric and training characteristics. The half-marathoners were heavier (P marathoners. They had fewer years of experience (P marathoners. For half-marathoners, body mass index (P = 0.011), percent body fat (P = 0.036) and speed in running during training (P marathoners, percent body fat (P = 0.001) and speed in running during training (P marathoners in the multi-variate analysis, r2 decreased to 0.45, therefore body mass index explained only 2% of the variance of half-marathon performance. Percent body fat was significantly and negatively related to running speed during training in both groups. To summarize, half-marathoners showed differences in both anthropometry and training characteristics compared to marathoners that could be related to their lower training volume, most probably due to the shorter race distance they intended to compete. Both groups of athletes seemed to profit from low body fat and a high running speed during training for fast race times.

    Aortic calcium, aortic valve calcium (AVC), and coronary artery calcium (CAC) have been associated with cardiovascular event risk. We examined the prevalence of thoracic aortic calcium (TAC) and AVC in relation to the presence and extent of CAC, cardiovascular risk factors, and estimated risk of coronary heart disease (CHD). In 2,740 persons without known CHD aged 20 to 79 years, CAC was assessed by electron beam- or multidetector-computed tomography. We determined the prevalence of TAC and AVC in relation to CAC, CHD risk factors, and predicted 10-year risk of CHD. A close correspondence of TAC and AVC was observed with CAC. TAC and AVC increased with age; by the eighth decade of life, the prevalence of TAC was similar to that of CAC (>80%), and 36% of men and 24% of women had AVC. Age, male gender, and low-density lipoprotein cholesterol were directly related to the likelihood of CAC, TAC, and AVC; higher diastolic blood pressure and cigarette smoking additionally predicted CAC. Body mass index and higher systolic and lower diastolic blood pressures were also related to TAC, and higher body mass index and lower diastolic blood pressure were related to AVC. Calculated risk of CHD increased with the presence of AVC and TAC across levels of CAC. TAC and AVC provided incremental value over CAC in association with the 10-year calculated risk of CHD. If longitudinal studies show an incremental value of aortic and aortic valve calcium over that of CAC for prediction of cardiovascular events, future guidelines for risk assessment incorporating CAC assessment may additionally incorporate the measurement of aortic and/or aortic valve calcium.

    Full Text Available Background. The aim was to study efficiency of pathogenetic therapy and dynamics of anthropometric indexes in obese women of childbearing age having different endocrine patho­logy before and 6 months later after treatment. Materials and methods. Under an etiologic factor the obese patients were divided into three groups: with polycystic syndrome of ovaries (PCOS (n = 30, hypothalamic obesity (n = 21 and with obesity and primary hypothyroidism (n = 20. All patients were examined using biochemical, hormonal methods of research, magnetic resonance tomography of pituitary. Results. The patients of the first and second groups had significant decrease of body mass index (BMI after 6 months of treatment, while patients of the third group did not attain significant decrease of BMI over 6 months of treatment. In addition, 10 patients of the first group became pregnant (19.5 %. The patients of the first and second groups had significant improvement of indexes as compared to average data of waist circumference and waist — hip ratio against the treatment, while the patients of the third group did not find significant changes of those indexes over 6 months of treatment. Conclusions. The treatment with metformine in obese patients significantly improves clinical indices and declines BMI. Optimization of treatment of obesity in women of reproductive age is based on the individual programs, the choice of which is determined by the values of anthropometric indices, hormonal and metabolic status, features of food behavior and personality-emotional sphere, menstrual and reproductive functioning. Realization of curative measures complex considering the worked out algorithm of individual selection of obesity therapy allows reduce effectively and retain the attained body weight, improves somatic and reproductive health for the women of reproductive age.

    Childhood dyslipidemia is a critical factor of lifelong health. Therefore, screening and controlling dyslipidemia from childhood is a practical healthy strategy. However, few studies have examined the performance of anthropometric predictors of dyslipidemia in Chinese children, let alone the potential gender and urban-rural disparity. Thus, we evaluated anthropometric indices predicting dyslipidemia by genders and living areas in Chinese children. Data were from a health and nutrition survey conducted in seven urban areas and two rural areas in China between 2011 and 2012. The serum lipid levels of the participants were compared between genders and living areas. The body mass index z-score (BMI z-score), waist-hip ratio (WHR), waist-height ratio (WHtR), and mid-upper arm height ratio (MaHtR) were used as predictors. The receiver operating characteristic (ROC) analysis was performed to investigate the ability of anthropometric indices predicting dyslipidemia. A total of 773 participants (average age = 9.3 ± 1.7 y) were included. The prevalence of dyslipidemia was 10.9%. Anthropometric indices were all significantly related to blood lipid profiles in boys after adjustment for age. The areas under the ROC curves (ACUs) were significantly larger than 0.5 in boys (ranged between 0.66-0.73), and were larger in rural boys (ranged between 0.68 and 0.94). MaHtR and WHR were associated with the highest specificity (93.8%) and highest sensitivity (100%), respectively. Using anthropometric indices, screening for dyslipidemia may be more appropriate in boys than in girls in China, especially in rural boys. The BMI z-score, WHR, WHtR, and MaHtR were all significantly associated with dyslipidemia in boys; using WHR and MaHtR as indicators achieved the highest sensitivity and specificity, respectively.

    Full Text Available Objectives: We sought to evaluate the relationship between gestational age (GA and neonatal anthropometric parameters, namely head circumference (HC and crown-heel length (CHL. Methods: We conducted a cross-sectional study in a tertiary care hospital with 530 consecutively live-born newborns of 28–41 weeks gestation. Anthropometric parameters were measured after three days of life. We summarized the variables using descriptive statistics, including percentile values, and the strength of association was determined through correlation analysis. The correlation was strong for HC and CHL, and linear regression analysis was done to develop predictive equations. Results: HC and CHL correlated well with GA with r-values of 0.863 and 0.859, respectively. The regression equations derived were GA (week = 9.2671 + [0.8616 × HC (cm] and GA (weeks = 7.2489 + [0.621 × CHL (cm]. Multiple regression gave the relationship as GA (weeks = 4.0244 + [0.4058 × HC (cm] + [0.4249× CHL (cm]. Application of this multiple regression equation to a test cohort of 30 babies for prediction of GA gave a mean margin of error of 2.9%, indicating that it is a satisfactory tool for prediction. Conclusions: HC and CHL can be used as simple tools for predicting GA in babies when this is in doubt. This can help in identification of high-risk newborns at primary care level without recourse to imaging modalities.

In the study were included 62 pupils (42 male and 20 female. The anthropometric tests were done in height, weight, biacromial and elbow breadth, subcutaneous adipose tissue at the : suprailiac skinfold; subscapular skinfold; triceps skinfold, as well as the abdominal circumference. The results showed that there was a heterogenic distribution of results, especially in the body weight, where the distribution between the minimal and maximal results is 28-70 kg, with the average 43, 14 ± 9, 78 of standard deviation with the male pupils, while with the female pupils was noticed more homogenous group and the standard deviation was significantly lower than with the female pupils in all variables. The findings show that almost in all measured variables female pupils are more developed at this age, especially the body high, body weight and subcutaneous adipose tissue, while as regards the abdominal circumference and body breadth, the male pupils are more developed. Comparison of symbolic sample of this research with the WHO data shows an approximate trend of raising and development of children which were included in this research, and the difference is as follows: Female pupils age 12, body height=151.97 cm

    This study investigates secular changes of anthropometric variables among four geographic groups in historical Yemen, to evaluate possible regional differences in the evolution of living standards. Nineteen somatic and cephalic measures collected by Coon in 1939, and 8 anthropometric indices in 1244 Yemenite adult males were analyzed. The individuals were divided into 10-year age groups. Within-group variations were tested by One-way ANCOVA (age as covariate). ANCOVA (controlling for age), and Forward stepwise discriminant analysis were used to evaluate and represent regional differences. ANCOVA and discriminant analysis confirmed and enhanced previous findings. At the time, the Yemenite population presented high intergroup heterogeneity. The highest mean values of height at all ages were found in the "mountain" region, which is characterized by very fertile soils and where, nowadays, most of the cereals and pulses are grown and where most livestock is raised. Within-group variations were limited and generally inconsistent in all geographic regions and concern vertical dimensions, but mean values of height never differed. The prolonged internal isolation of these groups resulted in significant regional morphometric differentiation. The main evidence comes from height which suggests that socioeconomic factors have played a role. Nevertheless, the possible better living conditions experienced by the "mountain" group, with the highest mean values of stature in all periods, did not allow the secular trend to take place in that region, too.

    2009-10-01

    Full Text Available Abstract Background Previous studies have suggested that increased plantar surface area, associated with pes planus, is a risk factor for the development of lower extremity overuse injuries. The intent of this study was to determine if a single or combination of foot anthropometric measures could be used to predict plantar surface area. Methods Six foot measurements were collected on 155 subjects (97 females, 58 males, mean age 24.5 ± 3.5 years. The measurements as well as one ratio were entered into a stepwise regression analysis to determine the optimal set of measurements associated with total plantar contact area either including or excluding the toe region. The predicted values were used to calculate plantar surface area and were compared to the actual values obtained dynamically using a pressure sensor platform. Results A three variable model was found to describe the relationship between the foot measures/ratio and total plantar contact area (R2 = 0.77, p R2 = 0.76, p Conclusion The results of this study indicate that the clinician can use a combination of simple, reliable, and time efficient foot anthropometric measurements to explain over 75% of the plantar surface contact area, either including or excluding the toe region.

    Sports anaemia is a physiological activity that occurs amongst footballers and may be due to poor diet, over-training, as well as an increase in plasma volume in endurance training activities. High plasma volume leads to changes in haematological parameters that may impact on endurance of footballers. The objective of the study was to determine the correlation between haematological and an-thropometric indices and their role in sports anaemia in a tropical setting. Venous blood was taken into EDTA for 12 soccer players of KNUST soccer team before training and after training for the first (W1) and fifth (W5) weeks of training sessions. Complete blood count analysis was done for each blood sample and anthropometric parameters such as height, weight, body mass index, body fat percent and lean body mass were also measured. Cross-tabulations with mean and standard deviation or median and range were computed. Paired t-test & and Mann-Whitney test for parametric and non-parametric data computations were carried out and a p-value ≤ 0.05 was taken to rep-resent significant difference between data groups. There was significant reduction in haemoglobin (p = 0.003), haematocrit (p = 0.002), mean cell volume (MCV) (p = 0.034) and red blood cell (RBC) count (p = 0.011) as a result of a significant expansion of plasma volume (p= 0.006). Neutrophil, lymphocyte and eosinophil counts were reduced significantly (p= 0.043, 0.001 and 0.007, respectively) after the training at W5. Lean body mass (LBM) inversely correlated with haemoglobin (r = -0.787, p = 0.002) and haematocrit (r = -0.588, p = 0.044). Body fat percentage (BFP) also negatively correlated with lymphocyte count (r = -0.700, p = 0.011). Furthermore, there was a positive correlation between body mass index (BMI) and plasma volume change after the training programme (r = 0.689, p = 0.013). The results suggest that sports anaemia was induced by an increase in plasma volume that resulted in changes in haematological

    To determine the adequacy of antenatal calcium intake in Malaysia, and the influencing factors. A cross-sectional study was conducted among postnatal women who delivered in two tertiary hospitals. Data were collected from antenatal cards, hospital documents and diet recall on daily milk and calcium intake during pregnancy. SPSS version 19.0 was used for statistical analyses. A total of 150 women were studied. The total daily calcium intake was 834 ± 43 mg (mean ± standard error of the mean), but the calcium intake distribution curve was skewed to the right with a median intake of 725 mg daily. When calcium intake from milk and calcium supplements was excluded, the daily dietary calcium intake was only 478 ± 25 mg. Even with inclusion of milk and calcium supplements, more than a third (n=55 or 36.7%) of the women consumed less than 600 mg calcium in their daily diet. The adequacy of daily calcium intake was not influenced by maternal age, ethnicity, income or maternal job or educational status as well as parity. The daily dietary calcium intake of the Malaysian antenatal population is far from adequate without the addition of calcium supplements and milk. © 2013 The Authors.

    Decreased lung function has health impacts beyond diagnosable lung disease. It is therefore important to understand the factors that may influence even small changes in lung function including obesity, physical fitness and physical activity. The aim of this study was to determine the anthropometric measure most useful in examining the association with lung function and to determine how physical activity and physical fitness influence this association. The current study used cross-sectional data on 4662 adults aged 40-79 years from the Canadian Health Measures Survey Cycles 1 and 2. Linear regression models were used to examine the association between the anthropometric and lung function measures (forced expiratory volume in 1 s [FEV 1 ] and forced vital capacity [FVC]); R 2 values were compared among models. Physical fitness and physical activity terms were added to the models and potential confounding was assessed. Models using sum of 5 skinfolds and waist circumference consistently had the highest R 2 values for FEV 1 and FVC, while models using body mass index consistently had among the lowest R 2 values for FEV 1 and FVC and for men and women. Physical activity and physical fitness were confounders of the relationships between waist circumference and the lung function measures. Waist circumference remained a significant predictor of FVC but not FEV 1 after adjustment for physical activity or physical fitness. Waist circumference is an important predictor of lung function. Physical activity and physical fitness should be considered as potential confounders of the relationship between anthropometric measures and lung function. Copyright © 2017.

    Full Text Available Background: First Nations people are experiencing increasing rates of obesity and type 2 diabetes but no anthropometric information exists from before the 1950s to provide context to these epidemics. Objective: To compare anthropometric indices of First Nations children and youth on first entering residential schools with historical and contemporary reference groups. Methods: This observational cross-sectional study used archival records from the Department of Indian Affairs to calculate body mass index (BMI, height for age (HA and weight for age (WA of all known children and youth undergoing physical examinations on first entering residential schools in Saskatchewan and Manitoba from 1919 to 1953. Proportions of children and youth in each BMI category were determined by age, sex, time period and residential school. Z-scores for HA and WA were determined by age group and sex. Finally, median heights and weights were compared with a non-Indigenous cohort from the 1953 Canadian survey. Results: On admission to residential schools, 1,767 First Nations children and youth (847 boys, 920 girls were more likely to have normal BMIs (79.8% than Canadian children and youth today (66.5%, but lower rates of overweight/obesity (10.9% vs. 32.0% and higher rates of underweight (9.3% vs. −2, age-specific median heights tended to be higher than Canadian children and youth in 1953. Under 3% of children and youth had WA Z-scores of >−2. Conclusions: A large majority of First Nations children and youth exhibited normal anthropometric indices on first entering residential schools in Manitoba and Saskatchewan from 1919 to 1953. These historical findings provide an important context to the current epidemics of obesity and type 2 diabetes and suggest that the nutritional conditions in these First Nations children's communities were satisfactory during the residential school era.

    During hospitalization, stroke patients are bedridden due to neurologic impairment, leading to loss of muscle mass, weakness, and functional limitation. There have been few studies examining respiratory muscle strength (RMS) in the acute phase of stroke. This study aimed to evaluate the RMS of patients with acute stroke compared with predicted values and to relate this to anthropometric variables, risk factors, and neurologic severity. This is a cross-sectional study in the acute phase of stroke. After admission, RMS was evaluated by maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP); anthropometric data were collected; and neurologic severity was evaluated by the National Institutes of Health Stroke Scale. The analysis of MIP and MEP with predicted values was performed by chi-square test, and the relationship between anthropometric variables, risk factors, and neurologic severity was determined through multiple linear regression followed by residue analysis by the Shapiro-Wilk test; P < .05 was considered statistically significant. In the 32 patients studied, MIP and MEP were reduced when compared with the predicted values. MIP declined significantly by 4.39 points for each 1 kg/m 2 increase in body mass index (BMI), and MEP declined significantly by an average of 3.89 points for each 1 kg/m 2 increase in BMI. There was no statistically significant relationship between MIP or MEP and risk factors, and between MIP or MIP and neurologic severity in acute phase of stroke. There is a reduction of RMS in the acute phase of stroke, and RMS was lower in individuals with increased age and BMI. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    Full Text Available The aim of the study was to compare the clinical and anthropometric characteristics of patients with COPD, which differ in the degree of airways obstruction and belong to groups A, B, C, D in accordance with GOLD, 2011 classification. A total of 112 ambulatory COPD patients in remission made the study sample. Anthropometric data, body mass index, medical history, dyspnea by mMRC scale, and spirometry was performed for all patients. There was confirmed that outpatients with COPD is a heterogeneous group, in which the majority are those with moderate (48.22 % and severe (30.36 %, airway obstruction. Despite the vast majority of men among outpatients, the percentage of women among patients with mild to moderate obstruction (22.58±5.31 % was significantly higher (p=0.002 as compared with those with severe or very severe limitation of airflow (6.00±3.36 %. Patients with severe and very severe obstruction were of significantly older age (p = 0.024. At the same time, the distribution of patients according to the GOLD, 2011 classification, demonstrate that all groups did not differ on any of the anthropometric indicators, including gender and age (p > 0.050. Distribution of patients by groups with different risk for future exacerbations is not a mirror image of gradation in accordance with the degree of airway obstruction. Every second (50.00±4.43 % of cases patient is included in group C and every tenth (10.20±4.32 % belongs to the group D not due to degree of bronchial obstruction, but due to the number of exa­cerbations in the past year. Therefore, in future studies it is advisable to use both principles of patients’ classification.

    Full text. A new anthropometric phantom of the human leg has been developed for calibrating in vivo measurements of stable lead in the bone using x-ray fluorescence. The phantom reproduces the shape and radiological characteristics of the midshaft of the human leg and includes tissue substitutes for cortical bone, bone marrow, and muscle which have been formulated using polyurethanes and calcium carbonate to provide the desired characteristics of density x-ray attenuation, and calcium content. The phantom includes a set of simulated tibia bones, each containing a precisely known concentration of stable lead, that can be easily inserted into the leg. Formerly, of a set of plexiglas cylinders filled with plaster of-paris, each containing a known lead content, was the consensus standard calibration phantom. Tissue substitute materials used in the new anthropometric calibration phantom are much more uniform in density and composition than the plaster-of-paris phantoms and its realistic appearance provides a practical means of evaluating the variability in measurements results due to the changes in subject-detector positioning. Use of the new anthropometric calibration phantom results in a energy spectrum that closely resembles the spectrum observed when measuring a human subject. The energy spectrum produced by the plaster-of-paris phantom lacks the substantial Compton Scattering component produced by the leg muscle mass which leads to unrealistic estimates of in vivo measurement sensitivity. The minimum detection limit (MDL) for in vivo measurement of stable lead in bone, using an efficiency derived from the new anthropometric phantom, ranges from 18,6 parts per million (ppm) to 26,3 ppm using the K β1,3 /Elastic ratio or the K 1 /Elastic ratio, respectively. These values are significantly greater than the MDL cited in the literature obtained using a efficiency derived the conventional cylindrical plaster-of-paris phantom. Likewise, the realistic shape of the new

    Full Text Available Calcium is an important nutrient for child development. The main objective of this study was to assess calcium intake and its adequacy with dietary reference intake (DRI in Spanish children. The ANIVA (Antropometría y Nutrición Infantil de Valencia study is a descriptive cross-sectional study. During two academic years 2013–2014 and 2014–2015, 1176 schoolchildren aged 6–9 years were selected from 14 primary schools in Valencia (Spain. Three-day food records were used to assess dietary intake, completed by parents/guardian. Anthropometric data (weight and height were evaluated in all subjects. Nutritional intake was compared to estimated average requirements (EARs and adequate intake (AI values to determine nutritional adequacy. A percentage of 25.77% had inadequate calcium intake, and a significantly higher prevalence was observed in girls (p = 0.006. Adequate calcium intake showed a positive association with the height z-score (p = 0.032. When assessing dietary patterns, schoolchildren with adequate calcium intakes had better nutritional adequacy in all nutrients, except cholesterol (p = 0.086 and fluorine (p = 0.503. These results suggest a public health problem that must be addressed through nutrition education programs to increase intake of calcium-rich food and to correct the associated dietary pattern.

    The WHO recommends the use of some anthropometric parameters as a screening resource for individuals under cardiometabolic risk. However, in the validation of these indicators, Brazilian women were not included. These women have different anthropometric profile compared to women who integrated the samples of the validation studies. We aimed to verify the accuracy of anthropometric indicators as a resource for the screening of women with hypertension. A cross-sectional study, with a probability sample of 3143 women (20-49 years) from the state of Alagoas (northeast of Brazil), was carried out. Hypertension was identified by systolic blood pressure (SBP) ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or regular use of antihypertensive drugs. The anthropometric indicators analyzed were BMI, waist circumference, waist-to-hip ratio, waist-to-height ratio (WHtR), body fat percentage, and conicity index. The accuracy definition of the indicators and the identification of best cut-off points were carried out on the basis of ROC curve analysis and Youden index, respectively. The prevalence of hypertension was 21.8%. All indicators used in hypertension identification had area under the ROC curve (AUC) >0.5. The WHtR with cut-off point of 0.54 was the best performance indicator (AUC = 0.72; P hypertension. In the absence of specific studies and considering the largest ethnic proximity and environmental/epidemiological similarity, the findings now obtained can be extended to women of other Brazilian states, especially those in the Northeastern region.

    For over one hundred years, the genetics of human anthropometric traits has attracted scientific interest. In particular, height and body mass index (BMI, calculated as kg/m2) have been under intensive genetic research. However, it is still largely unknown whether and how heritability estimates vary between human populations. Opportunities to address this question have increased recently because of the establishment of many new twin cohorts and the increasing accumulation of data in established twin cohorts. We started a new research project to analyze systematically 1) the variation of heritability estimates of height, BMI and their trajectories over the life course between birth cohorts, ethnicities and countries, and 2) to study the effects of birth related factors, education and smoking on these anthropometric traits and whether these effects vary between twin cohorts. We identified 67 twin projects including both monozygotic and dizygotic twins using various sources. We asked for individual level data on height and weight including repeated measurements, birth related traits, background variables, education and smoking. By the end of 2014, 48 projects participated. Together, we have 893,458 height and weight measures (52% females) from 434,723 twin individuals, including 201,192 complete twin pairs (40% monozygotic, 40% same-sex dizygotic and 20% opposite-sex dizygotic) representing 22 countries. This project demonstrates that large-scale international twin studies are feasible and can promote the use of existing data for novel research purposes. PMID:26014041

    The available information regarding the obesity pattern of the undergraduate female students of Kolkata is inadequate, though there are several reports which indicate the complications and/or awful consequences of obesity on female health particularly, during the reproductive years. The present investigation has thus been carried out to report their present physiological status along with the prevalence of obesity, based on their body mass index (BMI), some direct and derived anthropometric indices, and physical fitness. This small-scale cross-sectional study conducted in randomly selected 100 female students of different colleges of Kolkata with the age of 18-22 [mean age 20.4 (2.3)] years. Measurements of body composition included total 24 variables, with thirteen direct and eleven derived anthropometric variables; while physical efficiency parameters were physical fitness index, VO2max, energy expenditure and anaerobic power. The data of the experimental group were compared with those of the control group by t-test, using SPSS v.15.0 and MS-Excel v.2013. Analysis of collected data showed majority of the students have normal range of BMI (67.95%), but, 21.95% of students found to be overweight and 3.84% are obese. They also showed higher fat mass [14.40 (4.11)], but, lower waist-to-hip ratio and conicity index. They were found to have poor to moderate physical fitness [57.60 (3.90)] and higher energy expenditure [5.61 (0.72)]. The findings of the present obesity screening reports almost one of four female students (24 out of 100 participants) are overweight/obese, indicated higher body fat distribution and increased propensity of being obese with age. Thus, the overall data along with their low physical fitness points out to health risks among female undergraduates of Kolkata.

    For total body irradiation (TBI) dose calculation requirements, anatomical information about the whole body is needed. Despite the fact that video image grabbing techniques are used by some treatment planning systems for standard radiotherapy, there are no such systems designed to generate anatomical parameters for TBI planning. The paper describes an anthropometrical computerised system based on video image grabbing which was purpose-built to provide anatomical data for a PC-based TBI planning system. Using software, the system controls the acquisition and digitalisation of the images (external images of the patient in treatment position) and the measurement procedure itself (on the external images or the digital CT information). An ASCII file, readable by the TBI planning system, is generated to store the required parameters of the dose calculation points, i.e. depth, backscatter tissue thickness, thickness of inhomogeneity, off-axis distance (OAD) and source to skin distance (SSD).

    Full Text Available This paper presents anthropometric measurements regarding engineering students in India. Health survey (ergonomic assessment was carried out to know the health status of all students who have been using poorly designed furniture. The data were measured with the help of various tools. After data collection and analysis, authors came up with exhaustive dimensions for designing adjustable classrooms furniture. Dimensions recommended include; bench surface height, bench depth and width, back rest width and height, backrest angle, desk height, desk depth, width, and desk angle. Therefore, an implementation of these data will help to create comfortability, safety, well-being, suitability, reduce Musculoskeletal disorders, and improve performance of students in terms of attentiveness. Also, it is highly recommended to consider requirements from students in designing classrooms furniture and conduct seminar or workshop to educate students regarding the negative impact towards adapting poor posture in the long usage of classrooms furniture.

    This paper presents the results of an anthropometric survey of 138 rural Aymaran high-altitude males who were working as porters in La Paz, Bolivia (3700 m). All subjects were measured for stature, weight, upper arm circumference, and triceps skinfolds. The body size and composition of the porters were then compared to an Aymaran rural population from the Bolivian highlands, and urban mestizo labourers from La Paz. The porters were smaller than the urban sample, but appeared to be generally representative of rural Aymaran natives with respect to body size and composition, and nutritional status. It is suggested that towards one extreme of nutritional variability, some degree of undernutrition may be indicated, which should be considered in future studies of adaptation to hypoxia among these Andean highlanders.

    Anthropometric measurements and personal data were collected from 119 Australian Rules footballers from Victoria. A top level professional league team, a second level association team, and an A-grade amateur association team were observed, representing three levels of ability. The profile of physical features of these athletes at the beginning of the season is presented. A gradation of body size was observed between teams. The players in the top level team were slightly taller and heavier than those in the other teams. They had less body fat, as shown by lesser skinfold thicknesses, a smaller percentage body fat as determined by prediction equations, and a greater fat-free mass. The intermediate level team showed an intermediate level of body fat and the lower level team had the highest proportion of fat.

    It is stated that the indexing mechanism described can be used in a nuclear reactor fuel element inspection rig. It comprises a tubular body adapted to house a canister containing a number of fuel elements located longtitudinally, and has two chucks spaced apart for displacing the fuel elements longitudinally in a stepwise manner, together with a plunger mechanism for displacing them successively into the chucks. A measuring unit is located between the chucks for measuring the diameter of the fuel elements at intervals about their circumferences, and a secondary indexing mechanism is provided for rotating the measuring unit in a stepwise manner.

    Hybrid computational phantoms combine voxel-based and simplified equation-based modelling approaches to provide unique advantages and more realism for the construction of anthropomorphic models. In this work, a methodology and C++ code are developed to generate hybrid computational phantoms covering statistical distributions of body morphometry in the paediatric population. The paediatric phantoms of the Virtual Population Series (IT’IS Foundation, Switzerland) were modified to match target anthropometric parameters, including body mass, body length, standing height and sitting height/stature ratio, determined from reference databases of the National Centre for Health Statistics and the National Health and Nutrition Examination Survey. The phantoms were selected as representative anchor phantoms for the newborn, 1, 2, 5, 10 and 15 years-old children, and were subsequently remodelled to create 1100 female and male phantoms with 10th, 25th, 50th, 75th and 90th body morphometries. Evaluation was performed qualitatively using 3D visualization and quantitatively by analysing internal organ masses. Overall, the newly generated phantoms appear very reasonable and representative of the main characteristics of the paediatric population at various ages and for different genders, body sizes and sitting stature ratios. The mass of internal organs increases with height and body mass. The comparison of organ masses of the heart, kidney, liver, lung and spleen with published autopsy and ICRP reference data for children demonstrated that they follow the same trend when correlated with age. The constructed hybrid computational phantom library opens up the prospect of comprehensive radiation dosimetry calculations and risk assessment for the paediatric population of different age groups and diverse anthropometric parameters.

    The ZJU index is a novel model for detecting non-alcoholic fatty liver disease (NAFLD) that it is calculated based on combination of the body mass index, fasting plasma glucose, triglycerides, and the serum alanine aminotransferase-to-aspartate transaminase ratio. We aimed to evaluate the diagnostic accuracy of the ZJU index in detecting NAFLD in the Chinese population. This was a cross-sectional study. Anthropometric measurements, laboratory data, and ultrasonography features were collected through a standard protocol. The ZJU index, fatty liver index, hepatic steatosis index, lipid accumulation product, and visceral adiposity index were calculated. Then the predictive values of the five indices were compared according to the area under receiver-operating characteristic curve (AUROC) values. A total of 19,804 participants were recruited, of whom 7324 participants were diagnosed with NFALD and 12,480 subjects were regarded as controls. The AUROC value for NAFLD identification by the ZJU index was 0.925 (95% confidence interval [CI]: 0.919-0.931), which was significantly higher than the values for the other four models (P 60 years, the AUROC for the ZJU increased from 87.1 to 95.4%, values which were also greater than those for the other four indices. Analysis by sex also showed that the performance of the ZJU index in males and females was better than that of the other four indices. The ZJU index is an accurate and easy to employ tool for identifying NAFLD in the general Chinese population.

    Full Text Available The aim of our research was to describe the physical and anthropometric characteristics of 25 gymnasts from the talent identification program of the Extremeña Gymnastics Federation. Subjects were classified according to their specialty: women‘s artistic gymnastic (WAG and rhythmic gymnastics (RG. The dependent variables include body fat percentage through an electronic scale column with stadiometer (SECA 220cm; body circumferences through a plicometer (Holtain; body diameters and specific tests of flexibility through a tape (CM 3m; a heart rate through Ruffier test and a heart rate monitor (Polar F6; isometric strength of lower extremities through a load cell (SSMAJ 5000N; and jumping ability through a contact mat (Lafayette CVP A73. The results concluded that the WAG group got the best results in flexibility tests (p<.05. Also, the RG group had lower body fat percentage and greater SJ jump ability (r=-.774; p<.01 and CMJ (r=-.600; p<.05. However, the WAG group showed a negative relation between body mass index and flexibility (p<.01. We conclude that there are differences in body composition and physical tests between the specialties/styles of women’s artistic gymnastics and female rhythmic gymnastics; we also found relationships between the performance of such tests and anthropometric variables.

    Full Text Available Abstract Background We investigated the association between maternal anthropometric measurements in prepregnancy and at the end of pregnancy and their children's systolic (SBP and diastolic (DBP blood pressure at 11 years of age, in a prospective cohort study. Methods All hospital births which took place in 1993 in the city of Pelotas - Brazil, were identified (5,249 live births. In 2004, the overall proportion of follow-up was 85% and we obtained arterial blood pressure measurements of 4,452 adolescents. Results Independent variables analyzed included maternal prepregnancy weight and body mass index (BMI and maternal weight, and height at the end of pregnancy. Multiple linear regression analysis controlling for the following confounders were carried out: adolescent's skin color, family income at birth, smoking, alcohol intake during pregnancy, and gestational arterial hypertension. Mean SBP and DBP were 101.9 mmHg (SD 12.3 and 63.4 mmHg (SD 9.9, respectively. Maternal prepregnancy weight and BMI, and weight at the end of pregnancy were positively associated with both SBP and DBP in adolescent subjects of both sexes; maternal height was positively associated with SBP only among males. Conclusions Adequate evaluation of maternal anthropometric characteristics during pregnancy may prevent high levels of blood pressure among adolescent children.

    Full Text Available Purpose: The aim of this study was to assess the effects of zinc supplementation on anthropometric measures, improving lipid profile biomarkers, and fasting blood glucose level in obese people. Methods: This randomized, double- blind clinical trial was carried out on 60 obese participants in the 18-45 age range for one month. The participants were randomly divided into the intervention group, who received 30 mg/d zinc gluconate, and the placebo group who received 30mg/d starch. Anthropometric measurements (body mass index (BMI, weight and waist circumference were recorded before and at the end of study. Lipid profile biomarkers and fasting blood glucose were determined using enzymatic procedure. Analysis of Covariance (ANCOVA test was run to compare the post-treatment values of the two groups, and t-test was conducted to compare within group changes. Results: Serum zinc concentration was increased significantly in intervention group (p=0.024. BMI and body weight was significantly decreased (p=0.030 and p=0.020, respectively. Lipid profile biomarkers and fating blood glucose did not change significantly but triglyceride level was significantly decreased (p=0.006 in the intervention group. Conclusion: The obtained results indicate that zinc supplementation improves BMI, body weight, and triglyceride concentration without considerable effects on lipid profile and glucose level. Zinc can be suggested as a suitable supplementation therapy for obese people, but more studies are needed to verify the results.

    Full Text Available Background and Objectives: The amount of physical activity as an essential determinant of healthy lifestyle in females is less than is required. Theory-driven health education interventions, particularly Theory of Planned Behavior (TPB, are effective in promoting and sustaining physical activity. This research evaluated the TPB-based educational intervention on exercise behavior and anthropometric indices in females residing in organizational houses in Tehran. Materials and Methods: A randomized controlled trial was performed on 130 females residing in institutional houses in Tehran (2014. Participants were randomly chosen with multi-stage cluster sampling. The instructional sessions were carried out applying modified methods of the TPB structure (instrumental and affective attitudes, subjective norms, perceived behavioral control, intention and behavior. The TPB constructs, physical activity level and intensity, Body Mass Index (BMI and Waist Hip Ratio (WHR were analyzed using the SPSS 16software in baseline, three and six months post-education. Results: Conducting the educational program led to a rise and maintained the mean of the TPB constructs and mean rank of the physical activity level and intensity, three and six months post-intervention in the case group (P0.05 Conclusions: Implementing the TPB-directed instructional sessions resulted in ameliorating and sustaining exercise behavior and anthropometric indices in females.

    Full Text Available Anthropometric, lipid and glycemic parameters were compared in obese or overweight high-risk patients. This double-blind trial included 16 obese and overweight patients who followed a standard caloriecontrolled diet and received 15mg/day sibutramine or 1700mg/day metformin over three months. The changes observed in the sibutramine and metformin groups were, respectively: body mass index -6.0% and -4.0%; abdominal circumference -7.9% and -6.6%; fatty tissue -10.5% and -1.7%; total cholesterol -2.9% and -2.8%; LDL-C -0.01% and -0.1%; HDL-C -11.0% and -6.8%; total cholesterol/ HDL-C ratio +12.0% and +4.5%; HDL-C-to-LDL-C ratio -7.2% and -0.1%; triglycerides +14.0% and +22.3%; fasting glucose +4.3% and +1.4%; insulin -10.4% and -4.9%; HOMA -8.0% and -3.9%. Although the study was conducted with only 16 patients and the drugs were taken for only three months, we can see that sibutramine-treated obese or overweight highrisk patients showed a reduction of anthropometric parameters and better control of insulin resistance.

    Full Text Available This international comparative study between talented young handball players in Germany and Greece investigated specific physical and anthropometric characteristics. This investigation of both elite profiles will allow us to determine the differences in the selection system for elite young handball players between the two countries. One hundred and sixty-two players participated in this study, 88 Greek young male players and 74 German young male players. For anthropometric tests the players were measured for body height, body mass and body mass index, arm span, hand length and hand spread. Physical fitness measurements were 30 m sprint, standing long jump, sit and reach flexibility, and 20 m shuttle run test. The results of this study demonstrate that Greek players were taller and heavier (p<0.01, had longer arm span and hand length (p<0.01, and performed better in 30 m sprint (p<0.01, standing long jump (p<0.01 and aerobic capacity (p<0.01. German players outperform in hand spread (p=0.03. While some of these differences can be explained by the different strategies and training methods, and also the training environment, the results do have important implications and effects in the physical condition of junior players.

    Full Text Available Background: several studies show the influence of physical activity as a protective factor of the cardiovascular system. New evidence forcorroborating this are needed to ensure the prevention of cardiovascular disease. Objective: to determine the relationship between cardiovascular hyperactivity, physical activity and some homodynamic and anthropometric variables in normotensive individuals. Methods: a descriptive correlational cross-sectional study was conducted. The universe of the study consisted of the population between 15 and 74 of the municipality of Cienfuegos in 2010, the sample was 644. The variables were considered: sex, skin colour, age, height, weight, index of body mass, abdominal waist, blood pressures: systolic, diastolic, average and differential (basal and sustained weight test and physical activity. Pearson Chi- square test was calculated and t was applied for comparison of average independent samples with a significance level of p = 0,05. Prevalence ratios were determined with a confidence interval of 95 %. Results: the prevalence of cardiovascular hyperactivity was higher in the group of 65-74 years and males. Cardiovascular hyperactives showed values of the average hemodynamic variables studied cardiovascular over normoreactive. There is an association between physical activity and better cardiovascular response in normal weight individuals. Conclusions: there is an association between increased blood pressure and obesity in cardiovascular hyperactivity. Physical activity is associated with cardiovascular normoreactivity in normal weight.

    Full Text Available Recently, much attention is devoted to systemic inflammation in patients with chronic obstructive pulmonary disease (COPD. The aim of our study was to determine the relationship between clinical and anthropometric data with systemic inflammation in stable COPD patients. According to the study CRP levels were raised in 44% of patients (7.9 [7,1-10,9. Serum CRP was significantly higher in stable COPD patients than in control subjects (p=0.04. CRP correlated well with the pack/years index(p = 0,032 and disease duration (p=0,01. It wasn’t established link between CRP levels and height, weight, stage, disease category. CRP level affected the frequency of exacerbations (r=0,50; p=0,01. Patients with high CRP level had significantly more exacerbations in the past year (p=0.01. Patients who received any type of therapy for a long period of time had lower CRP levels, than patients who did not reseive any therapy.

    The aim of this study was to evaluate the effects of cessation of binge eating in response to placebo treatment in binge eating disorder (BED) on anthropometric, cardiovascular, and metabolic variables. We pooled participant-level data from 10 randomized, double-blind, placebo-controlled trials of medication for BED. We then compared patients who stopped binge eating with those who did not on changes in weight, body mass index (BMI), systolic and diastolic blood pressure, pulse, and fasting lipids and glucose. Of 234 participants receiving placebo, 60 (26%) attained cessation from binge eating. Patients attaining cessation showed modestly decreased diastolic blood pressure compared with patients who continued to binge eat. Weight and BMI remained stable in patients who stopped binge eating, but increased somewhat in those who continued to binge eat. Patients who stopped binge eating with placebo had greater reductions in diastolic blood pressure and gained less weight than patients who continued to binge eat. Self-report of eating pathology in BED may predict physiologic variables. Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.

    This paper aims to describe the nutritional status of Caboclo adolescents living in two areas of the Amazon Basin. Two cross-sectional studies, the first in the dry and the second in the wet season, were carried out in two Amazonian ecosystems: the forest and black water ecosystem, and the floodplain and white water ecosystem. Measurements of weight, stature, arm circumference and triceps, subscapular and suprailiac skinfolds were performed on 247 adolescents (10-19 years of age). Nutritional status was classified using body mass index according to international criteria and the prevalence of underweight and overweight was estimated. Linear mixed effects models were used with the anthropometric measurements as dependent variables and time interval, place of residence, sex, age and stature variation as independent variables. During the wet season, the prevalence of overweight among girls was higher in the forest (42%) than in the floodplain (9%). Longitudinal linear regression models showed that the arm circumference measurement was influenced both by seasonality and location, revealing that the increment between dry and wet seasons was less pronounced in the floodplain. At the time of the study, overweight already constituted a major public health concern among girls living in the forest area. In order to develop adequate public health policies for this important segment of the Amazon population further studies are necessary to investigate the role of environment and seasonality on the growth and nutritional status of adolescents.

    Ethnic differences in the pattern and trend of growth and weight have been described in studies of migrant populations. Our objective was to compare anthropometric parameters and overweight prevalence in third and fourth generation Japanese descendant preschoolers within the Peruvian preschool population. A total of 337 measurements of height and weight from 284 children, three to five years of age, were taken over three years in one Japanese-Peruvian preschool center in Lima, Peru. The data of each parameter were classified into three ethnic groups according to their parents' surnames: Japanese descendant children (n = 104), with both parents with Japanese surnames; Japanese-Peruvian descendant (n = 93), one parent with a Japanese surname and one with a non-Japanese surname; and Peruvian descendant (n = 140), both parents with non-Japanese surnames. We used the National Center for Health Statistics (NCHS) 2000 growth charts as reference values to obtain centiles, Z scores, and body mass index (BMI). In boys, the three groups differed significantly in height, weight, BMI, Z scores, and overweight prevalence. Peruvian descendant boys were taller and heavier than Japanese-Peruvian and Japanese descendants. Moreover, Japanese-Peruvian descendant boys were taller and heavier than Japanese descendant boys. In girls, there were no significant differences in height and weight and in overweight prevalence among the three ethnic groups. Japanese descendants in Peru have height, weight and BMI values similar to those of Japanese children in Japan but lesser than Peruvian children. These findings may be related to differences in ethnic background.

    Obesity is a critical problem among Mexican youth, but few studies have investigated associations among physical activity (PA) modes and anthropometrics in this population. This study examined associations among active commuting to school (ACS), sports or other organized PA, outdoor play, and body mass index (BMI) percentile and waist circumference (WC) among Mexican youth. Parents of school children (N = 1996, ages 6 to 14 years, 53.1% female) in 3 Mexican cities reported PA participation using the (modified) fourth grade School Physical Activity and Nutrition Survey. Trained assessors measured BMI percentile and WC in person. Parents reported that 52.3% of children engaged in ACS, 57.3% participated in sports or organized PA, and a median of 2 days in the previous week with at least 30 minutes of outdoor play. In complete case analyses (n = 857), ACS was negatively associated with BMI percentile, and outdoor play was negatively associated with WC after adjusting for school, age, sex, and income. In analyses incorporating data from multiple imputation (N = 1996), outdoor play was negatively associated with WC (all Ps obesity in Mexico. ACS and outdoor play should be priorities for increasing youth PA in Mexico.

    Full Text Available Health, as well as healthy lifestyle are and will be becoming in future increasingly topical because of the social, economic and ecological problems the present young generation is facing. The paradigm of man’s ecological development is based on the understanding of the interdependence and harmony between the individual’s physical, mental and personal development. With the development of the scientific knowledge of biosystems, such as human organism, scientists established that they are an organic unity of structural and functional characteristics that are at the same time relatively independent. In other words, human physique has structural characteristics determining the body shape and size, and in particular the shape and the size of the motor apparatus, but also the functional characteristics determining the biomechanical parameters of the individual’s motor activity. It is this motor activity, physical exercise and sport that are to play the most important social functions without which we could hardly imagine the prosperity of modern society, and in particular preserving and improving the individual’s health and efficiency. Considering the specifics of higher school and the constant dynamic changes in the social and economic life, the complex ecological and social problems in everyday life, as well as the decreasing motor activity of students, it was of interest to us to study the dynamics of the changes having occurred in some anthropometric and physiological indexes over a relatively long period of time.

    Calcium (Ca) is the most abundant mineral element in our body. It accounts for about 2% of body weight. The functions of calcium are: a) functions skeletal and b) regulatory functions. Bone consists of a protein matrix that mineralizes mainly with calcium (the most abundant), phosphate and magnesium, for it is essential an adequate dietary intake of Ca, phosphorus and vitamin D. The ionic Ca (Ca2+) is essential to maintain and / or perform different specialized functions of, virtually, all body cells cellular. Because of its important functions Ca2+ must be closely regulated, keeping plasma concentrations within narrow ranges. For this reason there is an accurate response against hypocalcemia or hypercalcemia in which the parathormone, calcitriol, calcitonin and vitamin K are involved. Ca intakes in the Spanish population are low in a significant percentage of the older adult’s population, especially in women. The main source of Ca in the diet is milk and milk derivatives. Green leafy vegetables, fruits and legumes can be important sources of Ca in a Mediterranean dietary pattern. The bioavailability of dietary Ca depends on physiological and dietary factors. Physiological include age, physiological status (gestation and lactation) Ca and vitamin D status and disease. Several studies relate Ca intake in the diet and various diseases, such as osteoporosis, cancer, cardiovascular disease and obesity.

    This book discusses the ways in which mathematical, computational, and modelling methods can be used to help understand the dynamics of intracellular calcium. The concentration of free intracellular calcium is vital for controlling a wide range of cellular processes, and is thus of great physiological importance. However, because of the complex ways in which the calcium concentration varies, it is also of great mathematical interest.This book presents the general modelling theory as well as a large number of specific case examples, to show how mathematical modelling can interact with experimental approaches, in an interdisciplinary and multifaceted approach to the study of an important physiological control mechanism.

    The precision, accuracy and reliability of the macro-combustion method is superior to the Knorr alkalimetric method, and it is faster. It also significantly reduces the calcium chromate waste accrual problem. The macro-combustion method has been adopted as the official method for determination of percent calcium carbonate in thermal battery grade anhydrous calcium chromate and percent calcium carbonate in quicklime used in the production of calcium chromate. The apparatus and procedure can be used to measure the percent carbonate in inorganic materials other than calcium chromate. With simple modifications in the basic apparatus and procedure, the percent carbon and hydrogen can be measured in many organic material, including polymers and polymeric formulations. 5 figures, 5 tables

    Gout is well known to be produced by increased uric acid level in blood. The objective of this paper is to assess the relationship between gout and calcium oxalate stone formation in the humans. 48 patients with combination of gout and calcium oxalate stone problem were included. The biochemical values of this group were compared with 38 randomly selected uric acid stone patients with gout, 43 stone patients with gout alone, 100 calcium oxalate stone patients without gout and 30 controls, making a total of 259 patients. Various biochemical parameters, namely serum calcium, phosphorus and uric acid and 24-h urine calcium, phosphorus, uric acid, oxalate, citrate and magnesium were analysed. ANOVA and Duncan's multiple-range tests were performed to assess statistical significance of the variations. The promoters of stone formation, namely serum calcium (P stone patients and gouty calcium oxalate stone patients compared to the non-gouty patients and controls. Urine oxalate (P stones patients. The inhibitor urine citrate (P stone gouty patients, followed by the gouty uric acid stone formers and gouty calcium oxalate stone patients. The high values of promoters, namely uric acid and calcium in the gouty stone patients indicate the tendency for urinary stone formation in the gouty stone patients. There is probably a correlation between gout and calcium oxalate urinary stone. We presume this mechanism is achieved through the uric acid metabolism. The findings point to the summation effect of metabolic changes in development of stone disease.

  19. Calcium Signaling in Taste Cells

    The sense of taste is a common ability shared by all organisms and is used to detect nutrients as well as potentially harmful compounds. Thus taste is critical to survival. Despite its importance, surprisingly little is known about the mechanisms generating and regulating responses to taste stimuli. All taste responses depend on calcium signals to generate appropriate responses which are relayed to the brain. Some taste cells have conventional synapses and rely on calcium influx through voltage-gated calcium channels. Other taste cells lack these synapses and depend on calcium release to formulate an output signal through a hemichannel. Beyond establishing these characteristics, few studies have focused on understanding how these calcium signals are formed. We identified multiple calcium clearance mechanisms that regulate calcium levels in taste cells as well as a calcium influx that contributes to maintaining appropriate calcium homeostasis in these cells. Multiple factors regulate the evoked taste signals with varying roles in different cell populations. Clearly, calcium signaling is a dynamic process in taste cells and is more complex than has previously been appreciated. PMID:25450977

    To determine the predictability of gestational diabetes mellitus (GDM) during the first trimester using the degree of insulin resistance and anthropometric measurements and to assign the risk of developing GDM by weight gained during pregnancy (WGDP). A total of 250 singleton pregnancies at 7-12 gestational weeks were studied. Body mass index (BMI), waist/hip ratio (WHR), quantitative insulin sensitivity check index (QUICKI), homeostasis model assessment-insulin resistance (HOMA-IR) scores and WGDP were determined. The backward stepwise method was applied to estimate possible associations with GDM. Cutoff points were estimated using receiver operating characteristic curve analysis. GDM was found in 20 of 227 singleton pregnancies (8.8 %). The calculated HOMA-IR, QUICKI, BMI, WHR, WGDP, and parity were significantly associated with GDM. Logistic regression analyses showed that three covariates (HOMA-IR, BMI, WGDP) remained independently associated with GDM. It was calculated as OR 1.254 (95 % CI 1.006-1.563), AUC 0.809, sensitivity 90 %, specificity 61 % with cutoff = 2.08 for HOMA-IR; OR 1.157 (CI 1.045-1.281), AUC 0.723, sensitivity 80 %, specificity 58 % with cutoff = 25.95 for BMI; OR 1.221, (CI 1.085-1.374), AUC 0.654, sensitivity 80 %, specificity 46 % with cutoff = 4.7 for WGDP. Despite a HOMA-IR score of >3.1 in pregnant women, GDM was detected in only three of 29 patients (10.3 %) if WGDP was HOMA-IR. In particular, if BMI is >25.95 kg/m(2) and the HOMA-IR score >2.08, controlling weight gain may protect against GDM.

    To analyse the prevalence of cardiovascular risk factors in healthy adolescents of low to middle socio-economic status and to study the influence of anthropometric, biological and lifestyle factors on the risk of metabolic syndrome (MetS). Cross-sectional study. BMI, waist circumference, blood pressure, fat and lean mass (by dual-energy X-ray absorptiometry), TAG, HDL-cholesterol, glucose, insulin, homeostatic model assessment-insulin resistance index (HOMA-IR), food intake and physical activity were measured. Cardiovascular risk factors were defined using the International Diabetes Federation criteria and insulin resistance using HOMA-IR ≥2.6. Bivariate and multivariate regressions examined the associations between MetS and anthropometric, biological and lifestyle factors. Observational cohort study including Chilean adolescents, who were part of a follow-up study beginning in infancy. Adolescents aged 16-17 years (n 667). In the sample, 16.2% had obesity and 9.5% had MetS. Low HDL-cholesterol (69.9%), abdominal obesity (33.3%) and fasting hyperglycaemia (8.7%) were the most prevalent cardiovascular risk factors. In males, obesity (OR=3.7; 95% CI 1.2, 10.8), insulin resistance (OR=3.0; 95% CI 1.1, 8.2), physical inactivity (OR=2.9; 95% CI 1.1, 7.7) and sarcopenia (OR=21.2; 95% CI 4.2, 107.5) significantly increased the risk of MetS. In females, insulin resistance (OR=4.9; 95% CI 1.9, 12.6) and sarcopenia (OR=3.6; 95% CI 1.1, 11.9) were significantly associated with MetS. High prevalences of obesity, abdominal obesity, dyslipidaemia, fasting hyperglycaemia and MetS were found in healthy adolescents. In both sexes, sarcopenia and insulin resistance were important risk factors of MetS. Promotion of active lifestyles at the school level and regulation of the sale of energy-dense foods are needed.

    Full Text Available Not much is known about the influence of dance on the morphological and anthropometric development of young and teenager dancers. Bibliography on the subject is almost nonexistent, given the difficulty to find studies about this type of population. It is very important to control the morphological development of girls that study dance in order to quantify, qualify and achieve better results. Therefore, the purpose of this study was to compare the anthropometric characteristics of two populations: one group of classical ballet dancers, average age 11.12 ± 1.00, from Porto Alegre, Brazil, and the other group including dancers of Spanish dance and classical ballet, with an average age of 11.50 ± 0.94, from Cordoba, Spain. A parallel was established between the populations, comparing and relating the data obtained. Fifty anthropometrical variables were measured, including body weight, stature, height, skinfolds, girths, breadths and lengths, based on the ISAK (International Society of the Advancement of kinanthropometry protocol, proposed by Ross and Marfell-Jones (1991. Descriptive statistical methodology was used in order to obtain a database for the two samples studied and the t test was used to compare their data. The conclusion was that the two groups are very similar despite the fact that a few statistically different variables were found. These differences were mainly related to breadths. RESUMO Pouco se sabe a respeito da influência da dança no desenvolvimento morfológico e antropométrico de meninas e adolescentes – meninas-bailarinas. A bibliografia referente a esse tema é quase inexistente, tendo-se grande dificuldade de encontrar estudos realizados acerca de populações desse tipo.

    Full Text Available Due to the importance of interdisciplinarity and multidisciplinarity to the complex analysis of human movement, and in an attempt to seek to bring Kinanthropometry and Biomechanics closer together, throughanthropometry, this review article was compiled in order to: present the historical evolution of anthropometry and the theoretical presuppositions on which its anthropometric models are based; to present anthropometry as a method for measurement in biomechanics; to describe the role and scope of anthropometry in biomechanics by discussing some of its applications and contributions. Initially, an analysis is made of historical and conceptual aspects and anthropometric models are presented and characterized together with their theoretical presuppositions and limitations. Anthropometry is then analyzed in the context of the different methods for measuring in biomechanics, studying its position within the process of analyzing human movement as a prerequisite of kinemetry and dynamometry and also of synchronized analysis. What follows is a refl ection on the role and scope of anthropometry within the analysis of movement, with examples from drawn from several studies, and an identifi cation of their respective contributions. Finally, some considerations resulting from this refl ection are presented; the degree of development of anthropometric models is identifi ed and the constant pursuit for improvement over recent years, with the use of ever more sophisticated techniques, is demonstrated.

However, it is unclear whether different anthropometric indicators of obesity can satisfactorily predict high blood pressure in the school setting. This study evaluated the sensitivity and specificity of body mass index, waist circumference, and waist to height ratio in the detection of high blood pressure in adolescents. The sample consisted of 8295 adolescents aged 10-17 years. Weight was measured using a digital scale, height with a stadiometer, and waist circumference using a tape measure. Blood pressure was measured by an automatic blood pressure measuring device. ROC curves were used for the analysis of sensitivity and specificity of the three anthropometric indices in identifying high blood pressure. Binary Logistic Regression was used to assess the association of body mass index, waist circumference, and waist to height ratio with high blood pressure. Low values of sensitivity were observed for body mass index (0.35), waist circumference (0.37), and waist to height ratio (0.31) and high values of specificity for body mass index (0.86), waist circumference (0.82), and waist to height ratio (0.83) in the detection of high blood pressure. An association was observed between adolescents classified with high body mass index (OR=3.57 [95% CI=3.10-4.10]), waist cirumference (OR=3.24 [95% CI=2.83-3.72]), and waist to height ratio (OR=2.94 [95% CI=2.54-3.40]) with high blood pressure. Body mass index, waist circumference, and waist to height ratio presented low sensitivity to identify adolescents with high blood pressure. However, adolescents classified with high body mass index, waist circumference, and waist to height ratio demonstrated a high association of presenting high blood pressure.

    A cross-sectional study of 183 female Bathudis, a tribal population of the Keonjhar District, Orissa, India, was undertaken to investigate age variations in anthropometric and body composition characteristics and nutritional status. The subjects were categorized into three age groups: 50 years. Height, weight, circumferences and skinfolds data were collected. Body mass index (BMI) and several body composition variables and indices were derived using standard equations. The results revealed that there existed significant negative age variations for most of the anthropometric and body composition variables and indices. Correlation studies of age with these variables and indices revealed significant negative correlations. Linear regression analyses revealed that for all variables, age had a significant negative impact. Studies on the nutritional status of these women revealed that with increasing age, there was an increase in the frequency of undernutrition. In conclusion, this study demonstrated that among Bathudi women, age was significantly negatively related with anthropometric and body composition variables and indices. Moreover, with increasing age, the level of undernutrition increased.

    Studies in persons without HIV infection have compared percentage body fat (%BF) and waist circumference as markers of risk for the complications of excess adiposity, but only limited study has been conducted in HIV-infected subjects. We compared anthropometric and magnetic resonance imaging (MRI)-based adiposity measures as correlates of metabolic complications of adiposity in HIV-infected and control subjects. The study was a cross-sectional analysis of 666 HIV-positive and 242 control subjects in the Fat Redistribution and Metabolic Change in HIV Infection (FRAM) study assessing body mass index (BMI), waist (WC) and hip (HC) circumferences, waist-to-hip ratio (WHR), %BF, and MRI-measured regional adipose tissue. Study outcomes were 3 metabolic risk variables [homeostatic model assessment (HOMA), triglycerides, and HDL cholesterol]. Analyses were stratified by sex and HIV status and adjusted for demographic, lifestyle, and HIV-related factors. In HIV-infected and control subjects, univariate associations with HOMA, triglycerides, and HDL were strongest for WC, MRI-measured visceral adipose tissue, and WHR; in all cases, differences in correlation between the strongest measures for each outcome were small (r HDL, WC appeared to be the best anthropometric correlate of metabolic complications, whereas, for triglycerides, the best was WHR. Relations of simple anthropometric measures with HOMA, triglycerides, and HDL cholesterol are approximately as strong as MRI-measured whole-body adipose tissue depots in both HIV-infected and control subjects.

The incidence of the intestine neoplasm in Brazil is at fourth among the most frequent tumors of the male sex, barely close to the stomach, lung and prostate incidences. Phantoms are objects used as simulators for investigating ionizing radiation transport on humans, especially during radiation therapy or radiological diagnostic. The purpose of this work is the achievement of a set of computerized tomography (CT) images of a male pelvis phantom, with anthropomorphic and anthropometric features. It investigates and analyses the set of phantom CT images in according to a correspondent human pelvis one. The reason to develop a pelvis phantom is the needs of reproducing well established spatial dose distribution in radiation therapy, especially during calibration and protocol setup for various pelvis neoplasms. It aims to produce dose optimization on radiation therapy, improving health tissue protection and keeping control tumor dose.

    Background: In postmenopausal women, the two major causes of bone loss are oestrogen deficiency after menopause and age related processes. Bone turnover increases to high levels and oestrogen deficiency may induce calcium loss by indirect effects on extra skeletal calcium homeostasis. Objective of this study was to evaluate calcium status in pre-menopausal and postmenopausal women. Methods: This cross sectional study was carried out in 34 premenopausal women and 33 postmenopausal women, in Department of Physiology, Services Institute of Medical Sciences, Lahore. Height and weight of each woman were taken to find out the body mass index (BMI). Serum calcium, parathyroid hormone and calcitonin levels of each subject were determined. Results: Premenopausal women were obese (BMI>30 Kg/m/sup 2/) while postmenopausal women were overweight (BMI>25 Kg/m/sup 2/). Serum calcium levels were significantly lower in postmenopausal women than in pre-menopausal women, while serum parathyroid hormone levels were significantly higher in postmenopausal woman. Serum calcitonin level was not significantly different in the two groups. Conclusion: Postmenopausal women are calcium deficient and have increased bone turnover as indicated by increased serum parathyroid hormone levels. (author)

    The aim of our study was to determine the differences in some anthropometric and physical performance variables of young Croatian female volleyball players (aged 13 to 15) in relation to playing position (i.e., independent variable) and performance level within each position (i.e., independent variable). Players were categorized according to playing position (i.e., role) as middle blockers (n=28), opposite hitters (n=41), passer-hitters (n=54), setters (n=30), and liberos (n=28). Within each position, players were divided into a more successful group and a less successful group according to team ranking in the latest regional championship and player quality within the team. Height and body mass, somatotype by the Heath-Carter method, and four tests of lower body power, speed, agility and upper body power (i.e., dependent variables) were assessed. Players in different positions differed significantly in height and all three somatotype components, but no significant differences were found in body mass, body mass index or measured physical performance variables. Players of different performance level differed significantly in both anthropometric and physical performance variables. Generally, middle blockers were taller, more ectomorphic, less mesomorphic and endomorphic, whereas liberos were shorter, less ectomorphic, more mesomorphic and endomorphic than players in other positions. More successful players in all positions had a lower body mass index, were less mesomorphic and endomorphic, and more ectomorphic than less successful players. Furthermore, more successful players showed better lower body power, speed, agility and upper body power. The results of this study can potentially provide coaches with useful indications about the use of somatotype selection and physical performance assessment for talent identification and development.

    The aim of this systematic review was to identify and summarize evidence of the association between anthropometric measurements and periodontal status in children and adolescents. We searched PubMed, Institute for Scientific Information Web of Knowledge, Cochrane Library, and 7 additional databases, following the guidance of Preferred Reporting Items for Systematic Reviews and Meta-Analyses, up to December 2014. Observational studies reporting data on the association between anthropometric measurements and periodontal diseases in 2–18-y-old participants were included. An initial search identified 4191 papers; 278 potentially effective studies (k = 0.82) and 16 effective studies (k = 0.83) were included after screening. The mean quality of evidence among the studies was 20.3, according to the Strengthening the Reporting of Observational studies in Epidemiology checklist (k = 0.79). Meta-analyses showed that obesity (measured by body mass index) was significantly associated with visible plaque index (OR: 4.75; 95% CI: 2.42, 9.34), bleeding on probing (OR: 5.41; 95% CI: 2.75, 10.63), subgingival calculus (OR: 3.07; 95% CI: 1.10, 8.62), probing depth (OR: 14.15; 95% CI: 5.10, 39.25) and flow rate of salivary secretion (standardized mean difference: −0.89; 95% CI: −1.18, −0.61). However, various results were reported in the effective studies that were not included in meta-analyses. In conclusion, obesity is associated with some signs of periodontal disease in children and adolescents. Further studies with a comprehensive prospective cohort design and more potential variables are recommended. PMID:26567204

    Alpine ski racing is known to be a sport with a high risk of injuries. Because most studies have focused mainly on top-level athletes and on traumatic injuries, limited research exists about injury risk factors among youth ski racers. The aim of this study was to determine the intrinsic risk factors (anthropometrics, biological maturity, physical fitness, racing technique) for injury among youth alpine ski racers. Study participants were 81 youth ski racers attending a ski boarding school (50 males, 31 females; 9–14 years). A prospective longitudinal cohort design was used to monitor sports-related risk factors over two seasons and traumatic (TI) and overuse injuries (OI). At the beginning of the study, anthropometric characteristics (body height, body weight, sitting height, body mass index); biological maturity [status age at peak height velocity (APHV)]; physical performance parameters related to jump coordination, maximal leg and core strength, explosive and reactive strength, balance and endurance; and ski racing technique were assessed. Z score transformations normalized the age groups. Multivariate binary logistic regression (dependent variable: injury yes/no) and multivariate linear regression analyses (dependent variable: injury severity in total days of absence from training) were calculated. T-tests and multivariate analyses of variance were used to reveal differences between injured and non-injured athletes and between injury severity groups. The level of significance was set to p jump contact time; and higher drop jump reactive strength index were at a lower injury risk or more vulnerable for fewer days of absence from training. However, significant differences between injured and non-injured athletes were only observed with respect to the drop jump reactive strength index. Regular documentation of anthropometric characteristics, biological maturity and physical fitness parameters is crucial to help to prevent injury in youth ski racing. The present

  17. Cardiovascular Effects of Calcium Supplements

    Directory of Open Access Journals (Sweden)

    Ian R. Reid

    2013-07-01

    Full Text Available Calcium supplements reduce bone turnover and slow the rate of bone loss. However, few studies have demonstrated reduced fracture incidence with calcium supplements, and meta-analyses show only a 10% decrease in fractures, which is of borderline statistical and clinical significance. Trials in normal older women and in patients with renal impairment suggest that calcium supplements increase the risk of cardiovascular disease. To further assess their safety, we recently conducted a meta-analysis of trials of calcium supplements, and found a 27%–31% increase in risk of myocardial infarction, and a 12%–20% increase in risk of stroke. These findings are robust because they are based on pre-specified analyses of randomized, placebo-controlled trials and are consistent across the trials. Co-administration of vitamin D with calcium does not lessen these adverse effects. The increased cardiovascular risk with calcium supplements is consistent with epidemiological data relating higher circulating calcium concentrations to cardiovascular disease in normal populations. There are several possible pathophysiological mechanisms for these effects, including effects on vascular calcification, vascular cells, blood coagulation and calcium-sensing receptors. Thus, the non-skeletal risks of calcium supplements appear to outweigh any skeletal benefits, and are they appear to be unnecessary for the efficacy of other osteoporosis treatments.

    To evaluate whether anthropometric parameters add to PSA measurements in middle-aged men for risk assessment of prostate cancer (PCa) diagnosis and death. After adjusting for PSA, both BMI and weight were significantly associated with an increased risk of PCa death with the odds of a death corresponding to a 10 kg/m2 or 10 kg increase being 1.58 (95% CI 1.10, 2.28; p = 0.013) and 1.14 (95% CI 1.02, 1.26; p = 0.016) times greater, respectively. AUCs did not meaningfully increase with the addition of weight or BMI to prediction models including PSA. In 1974 to 1986, 22,444 Swedish men aged 44 to 50 enrolled in Malmö Preventive Project, Sweden, and provided blood samples and anthropometric data. Rates of PSA screening in the cohort were very low. Documentation of PCa diagnosis and disease-specific death up to 2014 was retrieved through national registries. Among men with anthropometric measurements available at baseline, a total of 1692 men diagnosed with PCa were matched to 4190 controls, and 464 men who died of disease were matched to 1390 controls. Multivariable conditional logistic regression was used to determine whether diagnosis or death from PCa were associated with weight and body mass index (BMI) at adulthood after adjusting for PSA. Men with higher BMI and weight at early middle age have an increased risk of PCa diagnosis and death after adjusting for PSA. However, in a multi-variable numerical statistical model, BMI and weight do not importantly improve the predictive accuracy of PSA. Risk-stratification of screening should be based on PSA without reference to anthropometrics.

    The Obstructive Sleep Apnea Syndrome is a chronic disease characterized by episodes upper airway collapse, and has been associated with increased cardiovascular morbidity. To correlate the neck, abdominal and pelvic circumference with the AHI and oxyhemoglobin saturation in OSA patients, and to correlate these values with disease severity. A prospective descriptive study of 82 patients evaluated complaints suggesting OSA, from July 2008 to March 2010. All patients underwent polysomnography, an ENT clinical exam, measures of the BMI, abdominal, pelvic, and cervical circumferences. The mean, standard deviations and Spearman's correlations were analyzed. The mean AHI in men was 39 events/hr; in women it was 21 events/hr in women. The mean neck circumference was 34. 5 cm in women and 41. 3 cm in men, the mean abdominal circumference was 94. 3 cm in women and 101. 5 cm in men, and the pelvic circumference was 105. 7 cm in men and 108. 7 cm in women. The neck circumference correlated more closely to the AHI in men (r = + 0. 389 p = 0. 001). The relationship between the abdominal circumference correlated more with AHI than with the BMI in men (AbC r = + 0. 358 p = 0. 003 BMI r = + 0. 321 p = 0. 009). The neck circumference is the best anthropometric measurement of respiratory disorder severity compared to the AbC or the BMI.

    This study developed anthropometric information on U.S. firefighters to guide fire-apparatus seat and seatbelt designs and future standards development. A stratified sample of 863 male and 88 female firefighters across the U.S. participated in the study. The study results suggested 498 mm in width, 404 mm in depth, and 365-476 mm in height for seat pans; 429-522 mm in width and 542 mm in height for seat back; 871 mm in height for head support; a seat space of 733 mm at shoulder and 678 mm at hip; and a knee/leg clearance of 909 mm in fire truck cab. Also, 1520 mm of lap belt web effective length and 2828 mm of lap-and-shoulder belt web effective length were suggested. These data for fire-truck seats and seatbelts provide a foundation for fire apparatus manufacturers and standards committees to improve firefighter seat designs and seatbelt usage compliance.

    Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls.

  10. The Effects of Dietary Calcium and/or Iron Deficiency upon Murine Intestinal Calcium Binding Protein Activity and Calcium Absorption

    OpenAIRE

    McDonald, Catherine M.

    1980-01-01

    Iron deficiency has been shown to impair calcium absorption, leading to decreased bone mass. Vitamin D3-dependent calcium binding protein (CaBP) has been demonstrated to be necessary for the active transport of calcium in the intestine of numerous species. Iron deficiency might affect the activity of the calcium binding protein. Four experimental diets were formulated as follows: Diet 1, iron adequate, calcium adequate; Diet 2, iron deficient, calcium adequate; Diet 3, iron adequate, calci...

  11. Height and Weight Estimation From Anthropometric Measurements Using Machine Learning Regressions.

    2018-01-01

    Height and weight are measurements explored to tracking nutritional diseases, energy expenditure, clinical conditions, drug dosages, and infusion rates. Many patients are not ambulant or may be unable to communicate, and a sequence of these factors may not allow accurate estimation or measurements; in those cases, it can be estimated approximately by anthropometric means. Different groups have proposed different linear or non-linear equations which coefficients are obtained by using single or multiple linear regressions. In this paper, we present a complete study of the application of different learning models to estimate height and weight from anthropometric measurements: support vector regression, Gaussian process, and artificial neural networks. The predicted values are significantly more accurate than that obtained with conventional linear regressions. In all the cases, the predictions are non-sensitive to ethnicity, and to gender, if more than two anthropometric parameters are analyzed. The learning model analysis creates new opportunities for anthropometric applications in industry, textile technology, security, and health care.

  15. Calcium transport in turtle bladder

    International Nuclear Information System (INIS)

    Sabatini, S.; Kurtzman, N.A.

    1987-01-01

    Unidirectional 45 Ca fluxes were measured in the turtle bladder under open-circuit and short-circuit conditions. In the open-circuited state net calcium flux (J net Ca ) was secretory (serosa to mucosa). Ouabain reversed J net Ca to an absorptive flux. Amiloride reduced both fluxes such that J net Ca was not significantly different from zero. Removal of mucosal sodium caused net calcium absorption; removal of serosal sodium caused calcium secretion. When bladders were short circuited, J net Ca decreased to approximately one-third of control value but remained secretory. When ouabain was added under short-circuit conditions, J net Ca was similar in magnitude and direction to ouabain under open-circuited conditions (i.e., absorptive). Tissue 45 Ca content was ≅30-fold lower when the isotope was placed in the mucosal bath, suggesting that the apical membrane is the resistance barrier to calcium transport. The results obtained in this study are best explained by postulating a Ca 2+ -ATPase on the serosa of the turtle bladder epithelium and a sodium-calcium antiporter on the mucosa. In this model, the energy for calcium movement would be supplied, in large part, by the Na + -K + -ATPase. By increasing cell sodium, ouabain would decrease the activity of the mucosal sodium-calcium exchanger (or reverse it), uncovering active calcium transport across the serosa

    A pilot plant for production of calcium chromate has been scaled up to a small production facility at the General Electric Neutron Devices Department. In preparation for this scale-up, the process and final product were studied in order to evaluate problems not considered previously. The variables and processes studied included: (1) the determination of optimum drying temperature and time for product analysis; (2) the effect of the grade of lime used as the precipitating agent on the purity of the calcium chromate; (3) product purity when calcium chromate is precipitated by the addition of ammonium chromate to slaked lime; (4) the reagents best suited for cleaning calcium chromate spills; and (5) methods for determining hydroxide ion concentration in calcium chromate. The optimum drying time for the product before analysis is four hours at 600 0 C. Gases evolved at various temperatures during the drying process were carbon dioxide and water vapor. Technical grade lime produced calcium chromate of the highest purity. Both nitric and acetic acids were efficient dissolvers of calcium chromate spills. Direct titration of hydroxide ion with sulfuric acid gave an average recovery of 93% for samples spiked with calcium hydroxide. 1 figure, 17 tables

    Multiple studies have examined the role of anthropometric characteristics in ovarian cancer risk and survival; however, their results have been conflicting. We investigated the associations between weight change, height and height change and risk and outcome of ovarian cancer using data from a large population-based case-control study. Data from 699 ovarian cancer cases and 1,802 controls who participated in the HOPE study were included. We used unconditional logistic regression adjusted for age, race, number of pregnancies, use of oral contraceptives, and family history of breast or ovarian cancer to examine the associations between self-reported height and weight and height change with ovarian cancer risk. Cox proportional hazards regression models adjusted for age and stage were used to examine the association between the exposure variables and overall and progression-free survival among ovarian cancer cases. We observed an increased risk of ovarian cancer mortality and progression for gaining more than 20 pounds between ages 18-30, HR 1.36; 95% CI 1.05-1.76, and HR 1.31; 95% CI 1.04-1.66, respectively. Losing weight and gaining it back multiple times was inversely associated with both ovarian cancer risk, OR 0.78; 95% CI 0.63-0.97 for 1-4 times and OR 0.73; 95% CI 0.54-0.99 for 5-9 times, and mortality, HR 0.63; 95% CI 0.40-0.99 for 10-14 times. Finally, being taller during adolescence and adulthood was associated with increased risk of mortality. Taller stature and weight gain over lifetime were not related to ovarian cancer risk. Our results suggest that height and weight and their change over time may influence ovarian cancer risk and survival. These findings suggest that biological mechanisms underlying these associations may be hormone driven and may play an important role in relation to ovarian carcinogenesis and tumor progression.

    Full Text Available Kickboxing is one of the modern combat sports. The psychophysiological demands of a kickboxing competition require athletes to achieve high thresholds of several aspects of physical fitness. The aim of the current review is to critically analyse and appraise the kickboxer’s anthropometric, physiological, physical and psychological attributes with the activity profile and injury epidemiology in order to provide practical recommendations for training as well as new areas of scientific research. The available information shows that both amateur and elite-level male kickboxers are characterized by a higher proportion of mesomorphy with a well-developed muscle mass and low body fat percentage. While there is some variation in the maximum oxygen uptake of kickboxers, moderate to high cardio-respiratory levels are reported for these athletes. Regardless of kickboxers’ level, a high peak and mean anaerobic power output were reported. High-level kickboxing performance also requires well-developed muscle power in both the upper and lower limbs. Psychological factors contribute to success that requires high levels of self-confidence, motivation, dispositional hope and optimism, mental toughness/resiliency, and adaptive perfectionism. Psychological attributes also distinguished successful from less successful kickboxers. The activity-to-rest ratio was higher in elite (1:1 than both amateur and national-level (from 1:2 to 1:5 kickboxers, with no significant differences between rounds (round 1=1:4, and rounds 2 and 3=1:5 as well as between winners and losers in amateur and national-level simulated combats. These particular psychophysiological characteristics and performance aspects of kickboxers influence performance and could serve as guidance for training.

    Full Text Available Introduction: The handgrip strength (HS is related to ADL, when reduced can lead to significant functional limitations. Its measurement allows estimating the strength general state and is a health indicator. Objective: Analyze the correlation between HS and anthropometry in box genders. Methods: This is a descriptive correlational study with 100 healthy individuals, aged between 17 and 40 years, 50 men, mean age 28.0 years (± 7.0 and 50 women, mean age 23 years (± 4.2. We evaluated HS and forearm, wrist and hand perimeter. Statistical analyzes were obtained using means, standard deviations and Pearson Correlation Test. Results: Compared to women, men had higher HS mean values on both sides. Men showed 49.0 kgf (± 8.3 on the right and 46.0 kgf (± 8.5 on the left side; while women showed 26.0 kgf (± 5.4 on the right side and 24.0 kgf (± 5.3 on the left side. Discussion: The hand perimeter was the only anthropometric data that showed a significant correlation with the HS in both genders. The forearm and wrist perimeter was only significant in men, with a slight difference between the sides; the right side prevails over the left. Although women showed no significant correlations with the HS it was noted discrepancy of force in relation to laterality, with a predominance of HS on the right side. Conclusions: We conclude that there is a correlation between HS and anthropometry, and that laterality and gender are factors influencing HS.

    This study measured 21 anthropometric dimensions (ADs) of 94 Korean male helicopter pilots in their 20s to 40s and compared them with corresponding measurements of Korean male civilians and the US Army male personnel. The ADs and the sample size of the anthropometric survey were determined by a four-step process: (1) selection of ADs related to helicopter cockpit design, (2) evaluation of the importance of each AD, (3) calculation of required sample sizes for selected precision levels and (4) determination of an appropriate sample size by considering both the AD importance evaluation results and the sample size requirements. The anthropometric comparison reveals that the Korean helicopter pilots are larger (ratio of means = 1.01-1.08) and less dispersed (ratio of standard deviations = 0.71-0.93) than the Korean male civilians and that they are shorter in stature (0.99), have shorter upper limbs (0.89-0.96) and lower limbs (0.93-0.97), but are taller on sitting height, sitting eye height and acromial height (1.01-1.03), and less dispersed (0.68-0.97) than the US Army personnel. The anthropometric characteristics of Korean male helicopter pilots were compared with those of Korean male civilians and US Army male personnel. The sample size determination process and the anthropometric comparison results presented in this study are useful to design an anthropometric survey and a helicopter cockpit layout, respectively.

    There is growing interest in the association between anthropometric measurements and dental caries in childhood over time (life-course studies). The aim of this review was to identify and systematically review the evidence of the association between anthropometric measurements and dental caries in childhood over time. PubMed, Institute for Scientific Information (ISI) Web of Knowledge, the Cochrane Library, and 6 other databases were searched to identify effective articles. A systematic approach involving critical appraisal was conducted to examine the relation between anthropometric measurements and dental caries in preschool- and school-aged populations from longitudinal studies. An initial search identified 1338 studies, with 59 potentially effective studies (κ = 0.82) and 17 effective studies (κ = 0.88). The quality of reporting among the studies ranged from 19.5 to 30.0 according to the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) criteria. Among the effective studies, 2 studies in which caries was used to predict anthropometric measurements consistently found an inverse association and 15 studies in which anthropometric measurements were used to predict caries were inconsistent, with results appearing to be influenced by nonuniformity of assessments, setting, and procedure of measurements; age and ethnicity of participants; and confounders of dental caries. In conclusion, among >1000 studies identified, 17 informed this systematic review. The quality of reporting of these studies varied considerably. Evidence of the association between anthropometric measurements and dental caries is conflicting and remains inconclusive. PMID:25593143

    Full Text Available Studies in serum concentrations of cytokines was performed in 103 high-ranked athletes from the sports different by energy consumption (bobsleigh and shooting sports. We have shown that the cytokine concentrations (IL-4 и IL-18 in bobsleigh sportsmen were sufficiently higher than in shooters. I.e., the IL-4 concentration was 1.5±0.9 pg/mL in bobsledders, and 0.45±0.23 pg/mL in shooters (р < 0.05. The IL-18 concentration was 467.5±155.2 pg/mL in bobsledders and 304.5±126.8 pg/mL in shooters. Meanwhile, the IL-6 and IL-10 in blood serum showed only a tendency for increase. The IFNγ concentration in bobsledders did not differ from similar parameters in shooters. When comparing the data in females, the IL-4 and IL-10 figures were 3.7-fold higher in bobsledders for IL-4, and 2.34-fold higher for IL-10, when compared to the shooters. Analysis of cytokines in blood of athletes with high energy consumption has shown significant fluctuations of the given parameters in athletes of both sexes. We have not revealed any correlations between the cytokine contents in blood serum and main anthropometric parameters (body muscle mass, body index mass, energy comsumption. Moreover, increased contents of the cytokines was found in bobsledders at more intensive physical loads. Hence, the energy consumption influences the cytokine state parameters. However, all the cytokine values in athletes are within population norms which may due to adaptation of the athletes for high loads which may be determined by, e.g., adequate usage of specialized sport food for their nutrition.

    The relationship between skin-fold thickness and running has been investigated in distances ranging from 100 m to the marathon distance (42.195 km), with the exclusion of the half-marathon distance (21.0975 km). We investigated the association between anthropometric variables, prerace experience, and training variables with race time in 42 recreational, nonprofessional, female half-marathon runners using bi- and multivariate analysis. Body weight (r, 0.60); body mass index (r, 0.48); body fat percentage (r, 0.56); pectoral (r, 0.61), mid-axilla (r, 0.69), triceps (r, 0.49), subscapular (r, 0.61), abdominal (r, 0.59), suprailiac (r, 0.55), and medial calf (r, 0.53) skin-fold thickness; mean speed of the training sessions (r, -0.68); and personal best time in a half-marathon (r, 0.69) correlated with race time after bivariate analysis. Body weight (P = 0.0054), pectoral skin-fold thickness (P = 0.0068), and mean speed of the training sessions (P = 0.0041) remained significant after multivariate analysis. Mean running speed during training was related to mid-axilla (r, -0.31), subscapular (r, -0.38), abdominal (r, -0.44), and suprailiac (r, -0.41) skin-fold thickness, the sum of 8 skin-fold thicknesses (r, -0.36); and percent body fat (r, -0.31). It was determined that variables of both anthropometry and training were related to half-marathon race time, and that skin-fold thicknesses were associated with running speed during training. For practical applications, high running speed during training (as opposed to extensive training) may both reduce upper-body skin-fold thicknesses and improve race performance in recreational female half-marathon runners.

    Objective To study the diagnostic properties of hand/wrist and body measures according to validated clinical and electrophysiological carpal tunnel syndrome (CTS) severity scales. Methods We performed a prospective case-control study. For each case, two controls were enrolled. Two five-stage clinical and electrophysiological scales were used to evaluate CTS severity. Anthropometric measurements were collected and obesity indicators and hand/wrist ratios were calculated. Area under the receiver operating characteristic curves (AUC), sensitivity, specificity, and likelihood ratios were calculated separately by gender. Results We consecutively enrolled 370 cases and 747 controls. The wrist-palm ratio, waist-hip-height ratio and waist-stature ratio showed the highest proportion of cases with abnormal values in the severe stages of CTS for clinical and electrophysiological severity scales in both genders. Accuracy tended to increase with CTS severity for females and males. In severe stage, most of the indexes presented moderate accuracy in both genders. Among subjects with severe CTS, the wrist-palm ratio presented the highest AUC for hand measures in the clinical and electrophysiological severity scales both in females (AUC 0.83 and 0.76, respectively) and males (AUC 0.91 and 0.82, respectively). Among subjects with severe CTS, the waist-stature ratio showed the highest AUC for body measures in the clinical and electrophysiological severity scales both in females (AUC 0.78 and 0.77, respectively) and males (AUC 0.84 and 0.76, respectively). The results of waist-hip-height ratio AUC were similar. Conclusions Wrist-palm ratio, waist-hip-height ratio and waist-stature ratio could contribute to support the diagnostic hypothesis of severe CTS that however has to be confirmed by nerve conduction study.

    The aim of this study was to use the Malnutrition Universal Screening Tool (MUST) to assess the applicability of alternative versus direct anthropometric measurements for evaluating the risk for malnutrition in older individuals living in nursing homes (NHs). We conducted a cross-sectional survey in 67 NHs in Tuscany, Italy. We measured the weight, standing height (SH), knee height (KH), ulna length (UL), and middle-upper-arm circumference of 641 NH residents. Correlations between the different methods for calculating body mass index (BMI; using direct or alternative measurements) were evaluated by the intraclass correlation coefficient and the Bland-Altman method; agreement in the allocation of participants to the same risk category was assessed by squared weighted kappa statistic and indicators of internal relative validity. The intraclass correlation coefficient for BMI calculated using KH was 0.839 (0.815-0.861), whereas those calculated by UL were 0.890 (0.872-0.905). The limits of agreement were ±6.13 kg/m(2) using KH and ±4.66 kg/m(2) using UL. For BMI calculated using SH, 79.9% of the patients were at low risk, 8.1% at medium risk, and 12.2% at high risk for malnutrition. The agreement between this classification and that obtained using BMI calculated by alternative measurements was "fair-good." When it is not possible to determine risk category by using SH, we suggest using the alternative measurements (primarily UL, due to its highest sensitivity) to predict the height and to compare these evaluations with those obtained by using middle-upper-arm-circumference to predict the BMI.

    Obesity has become a major health problem in contemporary society and it is closely related to many chronic diseases, so it is an important issue for measuring adiposity accurately and predicting its future. Prevention and treatment of overweight and obesity has become one of the key prevention and treatment of metabolic disorders. In this study, we compared the ability of the four anthropometric indicators (body mass index, waist circumstance, waist-height ratio, waist-to-hip ratio) to identify metabolic disorders (hypertension, hyperlipidaemia, hyperglycemia and hyperuricemia) by receiver operating characteristic (ROC) curve analyses and to provide evidence for clinical practice. In this large scale cross-sectional study, 13,275 Han adults (including 7595 males and 5680 females) received physical examination between January, 2009 and January, 2010 in Xuanwu Hospital of Capital Medical University were investigated by the means of questionnaire, Meanwhile, the physical examination and serological results were recorded. A package known as Statistical Package for Social Scientist (SPSS) was employed to analyse the responses while t-test, one-way analysis of variance (ANOVA), ROC analysis and chi-square statistical methods were used to test the hypotheses. WC, WHtR, WHR and BMI were all significantly (P risk factors regardless of gender. And the area under the curve (AUC) of WHtR was significantly greater than that of WC, BMI or WHR in the prediction of hypertension, hyperlipidaemia, hyperglycemia and hyperuricemia. Our data show that WHtR was the best predictor of various metabolic disorders. The diagnostic value in descending order was WHtR > WHR > WC > BMI. Therefore we recommend WHtR in assessment of obese patients, in order to better assess the risks of their metabolic diseases. Copyright © 2015 The Royal Society for Public Health.

    To investigate the association between anthropometric indices and morphometrically determined vertebral deformity, the authors carried out a cross-sectional study using data from the European Vertebral Osteoporosis Study (EVOS), a population-based study of vertebral osteoporosis in 36 European centers from 19 countries. A total of 16,047 EVOS subjects were included in this analysis, of whom 1,973 subjects (915 males, 1,058 females) (12.3%) aged 50 years or over had one or more vertebral deformities ("cases"). The cases were compared with the 14,074 subjects (6,539 males, 7,535 females) with morphometrically normal spines ("controls"). Data were collected on self-reported height at age 25 years and minimum weight after age 25 years, as well as on current measured height and weight. Body mass index (BMI) and height and weight change were calculated from these data. The relations between these variables and vertebral deformity were examined separately by sex with logistic regression adjusting for age, smoking, and physical activity. In females, there was a significant trend of decreasing risk with increasing quintile of current weight, current BMI, and weight gain since age 25 years. In males, subjects in the lightest quintile for these measures were at increased risk but there was no evidence of a trend. An ecologic analysis by country revealed a negative correlation between mean BMI and the prevalence of deformity in females but not in males. The authors conclude that low body weight is associated with presence of vertebral deformity.

    Lower body esteem may decrease self-esteem and lead to adverse health effects in children. This study explored the role of anthropometric, behavioral, and social factors on body esteem in peripubertal girls. We evaluated associations of body esteem (measured by the Revised Body Esteem Scale) with body mass index (BMI), mother's BMI, puberty, physical activity, role models for appearance, and screen time among girls (ages 9 and 10) participating in the Jersey Girl Study (n = 120). Linear models were used to evaluate differences in body esteem scores. Overweight/obese girls had a significantly lower mean body esteem score compared with underweight/healthy weight girls {14.09 (95% confidence interval [CI]: 12.53-15.27) vs. 17.17 (95% CI: 16.87-17.43)}. Girls who were physically active for at least 7 hours per week had a significantly higher body esteem score than those who were less active, after adjusting for BMI (17.00 [95% CI: 16.62-17.32] vs. 16.39 [95% CI: 15.82-16.86]). Girls whose mothers were overweight/obese, who had entered puberty, and who cited girls at school or females in the media as role models had lower body esteem scores, but differences disappeared after adjusting for girl's BMI. A trend of higher body esteem scores was found for girls whose mothers were role models. Lower BMI and higher levels of physical activity are independently associated with higher body esteem score. Having classmates or girls/women in the media as role models may detrimentally affect girls' body esteem, but having mothers as role models may have a positive effect.

    Full Text Available The etiology of testicular germ cell tumors (TGCTs is poorly understood. Recent epidemiological findings suggest that TGCT risk is determined very early in life, although the available data are still conflicting. The rapid growth of the testes during puberty may be another period of vulnerability. Body size has received increasing attention as possible risk factor for TC. To clarify the relation of body size and its anthropometric variables to TGCT risk, the authors analyzed data from 272 cases and 382 controls with regard to height (cm, weight (Kg and body mass index (BMI; kg/m2. Overall, participants in the highest quartile of height were more likely to be diagnosed with TGCTs than participants in the lowest quartile of height, OR 2.22 (95% confidence intervals (CI: 1.25-3.93; adjusted; ptrend = 0.033. Moreover, histological seminoma subgroup was significantly associated with tallness, very tall men (>182 cm having a seminoma TGCT risk of OR=2.44 (95% confidence intervals (CI: 1.19-4.97; adjusted; ptrend = 0.011. There was also a significant inverse association of TGCT with increasing BMI (ptrend = 0.001; age-adjusted analysis and this association was equally present in both histological subgroups. These preliminary results indicate that testicular cancer is inversely associated with BMI and positively associated with height, in particular with seminoma subtype. Several studies have reported similar findings on body size. As adult height is largely determined by high-calorie intake in childhood and influenced by hormonal factors at puberty, increased attention to postnatal exposures in this interval may help elucidate the etiology of TGCTs.

    Full Text Available Among Kazakh-Chinese population in Xinjiang province of China, prevalence of obesity and hypertension were 40.1% and 50.3% respectively, the highest across all ethnic groups residing in this pastureland. Despite this, there remained a dearth of information regarding the association between the anthropometric measures [body mass index (BMI, waist circumference (WC, waist-hip ratio (WHR, Waist-to-height ratio (WHtR etc.] and indicators for hypertension control [achieved levels of systolic and diastolic blood pressures (SBP and DBP, pulse pressure index (PPI, ankle-brachial index (ABI etc.] among them.A cross-sectional study was conducted in Xinjiang to determine the distribution and inter-relationships of the anthropometric measures and indicators for achieved BP control as well as their predictors among hypertension patients of Kazakh-Chinese ethnicity. Out of 550 randomly selected patients, 516 completed the interview, anthropometry and BP assessments.In the sample population, average SBP, DBP and PP were 156.26±24.40mmHg, 87.55±14.73mmHg and 68.71±19.39mmHg respectively. Bivariate analysis identified age, gender, education, duration of hypertension, WC and BMI being factors influencing the achieved levels of BP. Adjusted multiple linear regression models elicited positive associations of age (βa = 0.152, p = 0.001 and duration of hypertension (βa = 0.132, p = 0.003 with achieved level of SBP as well as BMI (βa = 0.135, p = 0.002 with DBP. Age (βa = 0.207, p<0.001 and WHtR (βa = 0.304, p = 0.005 were positively and WC (βa = -0.406, p<0.001 was negatively associated with PPI. Increasing age (βa = -0.125, p = 0.005, female gender (βa = -0.122, p = 0.005 and 5years' duration of hypertension (βa = -0.091, p<0.039 were negatively associated with ABI. After adjustment for socio-demographic variables, hypertensive patients with (reference = without abdominal obesity had 93% (p = 0.013 higher odds of missing the target BP control.Anthropometric

    Obesity is a well-established independent risk factor for hypertension and other cardiometabolic disorders. However, the best anthropometric index of obesity that predicts or associates strongly with hypertension and related conditions remains controversial and inconclusive. This study compared the performance of eight anthropometric indices of obesity: body mass index (BMI), ponderal index (PI), waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), waist-height ratio (WHtR), body adiposity index (BAI) and conicity index (CI) as correlates and potential predictors of risk of hypertension and prehypertension in a Nigerian population, and also the possible effect of combining two or more indices in that regard. This church-based, cross-sectional study was conducted in Anambra state, south-eastern Nigeria from 2012 to 2013. A total of 912 persons (436 male and 476 female) drawn randomly from three major cities (Awka, Onitsha and Nnewi) in the state participated in the study. Information on demography, medical history and lifestyle were obtained using a well-structured and validated questionnaire. The systolic/diastolic blood pressure and anthropometric measurements were taken by well-trained personnel. The resulting data were analysed using descriptive statistics, logistic regression, Poisson regression and receiver operating characteristic curve analysis. The mean values of all the anthropometric indices studied increased from normotension, through prehypertension to hypertension in both genders. BMI, WC, HC and CI were significantly higher (p blood pressure. BMI, WHtR, WC and PI (with higher correlation coefficients for blood pressure) showed the best potential to predict hypertension and prehypertension in the study: BMI (cut-off = 24.49, AUC = 0.698; cut-off = 23.62, AUC = 0.659), WHtR (cut-off = 0.55, AUC = 0.682; cut-off = 0.5, AUC = 0.636), WC (cut-off = 91.44, AUC = 0.692; cut-off = 82.55, AUC = 0.645), PI (cut-off = 14.45, AUC = 0.670; cut

    Full Text Available Abstract Background Maternal stature and body mass indices (BMI of non-pregnant women (NPW of child bearing age are relevant to maternal and offspring health. The objective was to compare anthropometric indices of NPW in four rural communities in low- to low-middle income countries (LMIC. Methods Anthropometry and maternal characteristics/household wealth questionnaires were obtained for NPW enrolled in the Women First Preconception Maternal Nutrition Trial. Body mass index (BMI, kg/m2 was calculated. Z-scores were determined using WHO reference data. Results A total of 7268 NPW participated in Equateur, DRC (n = 1741; Chimaltenango, Guatemala (n = 1695; North Karnataka, India (n = 1823; and Thatta, Sindh, Pakistan (n = 2009. Mean age was 23 y and mean parity 1.5. Median (P25-P75 height (cm ranged from 145.5 (142.2–148.9 in Guatemala to 156.0 (152.0–160.0 in DRC. Median weight (kg ranged from 44.7 (39.9–50.3 in India to 52.7 (46.9–59.8 in Guatemala. Median BMI ranged from 19.4 (17.6–21.9 in India to 24.9 (22.3–28.0 in Guatemala. Percent stunted (<−2SD height for age z-score ranged from 13.9% in DRC to 80.5% in Guatemala; % underweight (BMI <18.5 ranged from 1.2% in Guatemala to 37.1% in India; % overweight/obese (OW, BMI ≥25.0 ranged from 5.7% in DRC to 49.3% in Guatemala. For all sites, indicators for higher SES and higher age were associated with BMI. Lower SES women were underweight more frequently and higher SES women were OW more frequently at all sites. Younger women tended to be underweight, while older women tended to be OW. Conclusions Anthropometric data for NPW varied widely among low-income rural populations in four countries located on three different continents. Global comparisons of anthropometric measurements across sites using standard reference data serve to highlight major differences among populations of low-income rural NPW and assist in evaluating the rationale for and the design of optimal

    Full text: Introduction: Stunting is a multifactorial phenomenon with a high prevalence in developing countries. Helicobacter pylori, a bacterium that colonizes the gastric mucosa, has been related to growth impairment due to micronutrient malabsorption. However this hypothesis remains controversial. Objective: The aim of our work was to determine anthropometric indicators in children referred to a Tertiary-level Public Health Care Institution from Buenos Aires, Argentina, for upper gastrointestinal symptoms evaluation. Methods: 525 children (4-16 y) assisting to the Gastroenterology Unit of the Hospital de Niños “Sor María Ludovica”, La Plata, Argentina, were diagnosed for H. pylori infection by the 13C-Urea Breath Test. Weight and height were measured for calculation of anthropometric indicators height for age (HAZ), weight for age (WAZ) and Body Mass Index for age (BMI) using the Anthro Plus 2007 software of the World Health Organization. Statistical analysis was performed by Student’s t Test, Mann-Whitney Test and lineal regression. Results: Prevalence of H. pylori infection was 25.1% (95% CI, 21.5-29.5), with a mean age of the children similar in both groups, 10.1y (95% CI, 9.8-10.3y). Mean HAZ and WAZ were -0.40 (95% CI, -0.57-[-0.22]) and -0.31 (95% CI, -0.51-[-0.11]) in the positive group, and -0.18 (95% CI, -0.28-[-0.09]) and -0.10 (95% CI, -0.21-0.01) in the negative group. HAZ was significantly lower in the positive group (p = 0.04), while no significant differences were found for WAZ (p = 0.07) and BMI for age (p = 0.20) between both groups. However, after adjusting for confounding factors these differences were no longer significant. Stunting was found in 4.5% (95% CI, 2.1-9.6) and 3.3% (95% CI, 1.9-5.6) of the H. pylori positive and negative children respectively, while underweight was observed in 5.3% (95% CI, 2.6-10.5) and 6.7% (95% CI, 4.6-9.6) of the above mentioned groups. Conclusions: Prevalence of stunting and underweight were low in

    Full Text Available Background. Salivary constituents have a wide range of functions including oral calcium homeostasis. Salivary proteins such as statherin inhibit crystal growth of calcium phosphate in supersaturated solutions and interact with several oral bacteria to adsorb on hydroxyapatite. Concurrently, saliva, which is supersaturated with respect to calcium phosphates, is the driving force for plaque mineralization and formation of calculus. Thus, the aim of the present study was to estimate and correlate salivary statherin and calcium concentration to the dental calculus formation. Methods. A cross-sectional study was conducted to assess the relationship between salivary statherin, calcium, and dental calculus among 70 subjects, aged 20–55 years. Subjects were divided into 3 groups based on the calculus scores as interpreted by Calculus Index which was followed by collection of whole saliva using Super•SAL™. Salivary calcium levels were assessed by calorimetric method using Calcium Assay kit (Cayman Chemical, Michigan, USA and statherin levels by using ELISA Kit (Cusabio Biotech. Results. Statherin levels showed a weak negative correlation with the calcium levels and with calculus formation. The mean salivary statherin and calcium concentration were found to be 0.96 μg/ml and 3.87 mg/ml, respectively. Salivary statherin levels differed significantly among the three groups (p<0.05. Conclusions. Our preliminary data indicates that statherin could possibly play a role in the formation of dental calculus.

    Full Text Available Context: Nutrition plays a vital role in the quality of life in postmenopausal women. Aim: The aim is to determine the dietary intake, physical activity, and assess the body mass index (BMI among postmenopausal women. Settings and Design: A community-based sample survey. Materials and Methods: The present study included 140 postmenopausal women (40–70 years from Udupi, Manipal areas of Karnataka. The study was carried out between July and December 2013. Sociodemographic data were collected using a questionnaire. Anthropometric data included height, weight, waist, and hip circumference. Dietary intake was determined using 24 h dietary recall. Physical activity information was collected. Statistical Analysis Used: Data were analyzed using SPSS version 16 software. Paired t-test was performed to determine the dietary adequacy. Results: Obesity was 42.1% among the study participants. Increased WHR and waist circumference were 82.1% and 77.1%. Mean daily intake of calcium and saturated fatty acids were significantly higher than recommended dietary allowance (RDA (P < 0.001. Mean intake of energy, protein, carbohydrate, mono and poly unsaturated fatty acid, fiber and sodium were significantly lower than RDA (P < 0.001. Average daily intake of cereals, pulses, roots and tubers, meat and products, fats and oils, green leafy, and other vegetables were significantly (P < 0.001 lower than RDA. Intake of fruits, milk and milk products, and sugar was significantly higher (P < 0.001 than RDA. Only 37.1% of women performed moderate or active exercises regularly. Conclusions: Even though, nutrient and food group deficiencies were observed among postmenopausal women physical inactivity and effects of menopausal transition instigate increased BMI imposing a need to educate on nutrition and physical activity.

Students’ anthropometric parameters and PF levels—assessed via the Eurofit test battery—were measured by trained physical education teachers and evaluated according to the available norms, while their lifestyle habits were assessed through a questionnaire.ResultsIn all applied PF tests, students’ performance was negatively associated with the presence of obesity and central obesity, defined through international criteria for body mass index and waist to height ratio, respectively. According to multiple logistic regression analysis, the presence of overweight/obesity [odds ratio (OR: 4.43, 95% confidence interval (CI: 3.98–4.93], low adherence to the MD (KIDMED ≤ 3 (OR: 1.27, 95% CI: 1.09–1.48, and increased time spent in sedentary activities (>2 h per day (OR: 1.16, 95% CI: 1.03–1.29 were positively associated with poor PF, after adjusting for age and sex. In contrast, for every 1 day increase in the weekly frequency of engagement in athletic activity, the probability of poor PF decreased by 26% (OR: 0.74, 95% CI: 0.72–0.77. In a similar model, the presence of central obesity emerged as an even stronger possible predictor of poor PF (OR: 5.20, 95% CI: 4.66–5.78, compared to the presence of general obesity.ConclusionHigher general or abdominal adiposity, as well as the adoption of a low-quality diet and a sedentary lifestyle, is strongly associated with low PF levels during childhood.

    To perform a comparative analysis of anthropometric data from Suruí, Xavánte and Wari' indigenous children under 60 months of age using the NCHS/1977 and the WHO/2005 growth curves. Anthropometric measurements followed standard procedures and the data obtained were converted into z scores using the Epi-Info (Version 3.4) and WHO-Anthro (Version Beta) softwares. The indices height/age (H/A), weight/age (W/A) and weight/height (W/H) were descriptors of nutritional status for all children under 60 months of age, as well as the body mass index (BMI) for children 24-59 months old. The frequencies of Suruí children Wari' 61.7 and 68.3%. The frequencies of Suruí children Wari' 51.7 and 45.0%. None of the Suruí children were Wari' 1.7 and 0.0%. The frequencies of Suruí children > 2 z scores for W/H were 3.9 (NCHS/1977) and 3.9% (WHO/2005); Xavánte 0.0 and 0.8%; Wari' 0.0 and 0.0%. The frequency of Suruí children aged 24-59 months > 2 z scores for BMI was 5.4% (WHO/2005); Xavánte 9.5%; and Wari' 0.0%. Our findings revealed important differences in the results from nutritional assessment, according to the set of growth curves used; however, the use of both growth curves revealed a high prevalence of malnutrition. Therefore, future studies with indigenous populations should present their results using two sets of growth curves to allow consistent comparison.

    Full Text Available The objective of this paper is to examine the frequency of nutritional status and the relations between anthropometric characteristics and motor skills of the first-grade elementary schools girls from Valjevo. A battery of 16 anthropometric measurements and 9 motor tests was conducted on the pertinent sample (N = 332 of seven-year-old girls. Data were analyzed using common measures of central tendency, measures of variability and canonical correlation analysis. Based on the measured body mass index, 75% of participants have normal body mass, 21% has increased body mass, and 4% is overweight. The results showed that in the group of participants with normal body mass there is no significant connection between two systems of variables (morphological characteristics and motor skills. Data from the group of overweight participants show that the two statistically relevant correlations were extracted in the morpho-motoric space and were interpreted as canonical functions: (1 circular dimensionality of the skeleton and body mass, and explosive strength and (2 subcutaneous fatty tissue and segmented run and running speed. Canonical factors indicate that the greater the size of chest, thigh, shin and body mass, the lower are the results of the composite motor tests (plyometric jump, forward lean-backward lean-throw, long jump and standing jump, that is the girls who had higher values of back skinfold, stomach skinfold, thigh skinfold and shin skinfold, had worse result realization of motor tasks (hand-tapping, foot-tapping and running 5 x 10 m. Empirical data of the research on the isolated canonical structure are relevant from the theoretical point of view, but they also have relevant implications for identifying increased level of nutritional status and the advancement of physical education in elementary school education.

    Full Text Available Weight gain and related metabolic syndrome (MS are major current issues in public health. MS consists of abdominal fat, atherogenic dyslipidemia, hypertension, hyperglycemia, insulin resistance, pro-inflammatory and pro-thrombotic state, and accounts for both cardiovascular diseases and type II diabetes mellitus risk factors. Patients affected by psychiatric illness present a prevalence of 35–40% of MS. Many studies have shown that Mediterranean diet is associated with the reduction of mortality due to cardiovascular and malignant diseases, potentially preventing both obesity and type II diabetes mellitus. Our pilot study explores the effects of a 12-month healthy lifestyle program (Mediterranean diet and mild physical activity on metabolic and anthropometric parameters of patients affected by chronic psychiatric disorders who live in a psychiatric community facility. A Mediterranean diet was provided by a senior nutritional clinician and adapted by two dieticians, according to the needs and preferences of the community population. Concomitantly, a program of moderate physical activity, consisting in 30-min walks on level ground 4days a week, and psycho-educational group sessions with educational and therapeutic purposes were implemented. The metabolic and anthropometric parameters of our patients improved after both 6 (T6 and 12 (T12 months. Body Max Index was statistically significantly reduced at T6 and T12, with patients perceiving good quality of life. These positive outcomes suggest that a low-cost healthy lifestyle program can produce good adherence and feasibility even among patients with chronic psychiatric diseases, reducing their risk for MS, cardiovascular diseases and other complications.

    Full Text Available Abstract Background To analyze the strength of association between self-rated health and six anthropometric and body composition measures to explore the best indicator. Methods Analyses were based on the cross-sectional data from the China Kadoorie Biobank Study and approximately 300,000 adults were analyzed. Logistics regression was used to analyze the association between self-rated health (good or poor and anthropometric and body composition measures (height, weight, body mass index (BMI, waist circumference (WC, hip circumference (HC and body fat percentage, waist-to-hip ratio and waist-to-height ratio. Stratified analyses were undertaken to understand the effect modification of socioeconomic status on the association. Result Odds ratio of self-rated better health had an inverted U-shape association with weight, BMI, WC and body fat, with weight levels increasing until around 73.8 and 65.7 kg for male and female, BMI around 26.8 kg/m2, WC around 85.8 and 87.6 cm, body fat around 24.3 and 36.3%, and then declining thereafter. Height and HC also indicated a slightly inverted U-shape association. The strongest association was observed after adjustment was weight, with one standard deviation greater weight associated with 10.2% and 10.6% increased odds in male and female. Conclusions Being underweight and overweight are both risk factors for poor self-rated health in males and females, and weight is the best indicator of self-rated health compared with other measures.

    To describe the association between fat mass index and fat-free mass index values and factors associated with cardiovascular risk in adolescents in the city of Juiz de Fora, Minas Gerais. Cross-sectional study with 403 adolescents aged 10-14 years, from public and private schools. Anthropometric, clinical, biochemical measurements were obtained, as well as self-reported time spent performing physical exercises, sedentary activities and sexual maturation stage. Regarding the nutritional status; 66.5% of the adolescents had normal weight; 19.9% were overweight and 10.2% were obese. For both genders, the fat mass index was higher in adolescents that had high serum triglycerides, body mass index and waist circumference. Adolescents that had anthropometric, clinical and biochemical characteristics considered to be of risk for the development of cardiovascular disease had higher values of fat mass index. Different methodologies for the assessment of body composition make health promotion and disease prevention more effective. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    Laser scanning confocal microscopy in combination with the fluorescent calcium indicators Fluo-3 and Fura-Red was employed to estimate the intracellular concentration of free calcium ions in individual olfactory receptor neurons and to monitor temporal and spatial changes in the Ca(2+)-level upon stimulation. The chemosensory cells responded to odorants with a significant increase in the calcium concentration, preferentially in the dendritic knob. Applying various stimulation paradigma, it was found that in a population of isolated cells, subsets of receptor neurons display distinct patterns of responsiveness.

    Calcium carries messages to virtually all important functions of cells. Although it was already active in unicellular organisms, its role became universally important after the transition to multicellular life. In this Minireview, we explore how calcium ended up in this privileged position. Most likely its unique coordination chemistry was a decisive factor as it makes its binding by complex molecules particularly easy even in the presence of large excesses of other cations,...

    By means of homogeneous precipitation it has been possible to synthesize crystalline solid solutions of calcium strontium hydroxyapatite from aqueous solutions. The lattice constants for the solid solutions were measured in the range Ca 9 Sr(PO 4 ) 6 (OH) 2 - CaSr 9 (PO 4 ) 6 (OH) 2 . The investigations show that the discrimination of strontium against calcium is considerably smaller than reported elsewhere (1). Strontium is preferentially built into the c-axis direction of the apatite lattice

    In Experiment 1, 10 microCi 45 Ca/day were administered to 125 hens for 10 days. Hens were then allocated to five treatments with calcium levels ranging from .08 to 3.75% of the diet. In Experiment 2, hens with morning oviposition times were randomly allocated to 11 treatments that were periods of time postoviposition ranging from 6 hr to 24 hr, in 2-hr increments (Experiment 2). At the end of each 2-hr period, eggs from 25 hens were removed from the uterus. The 18-, 20-, and 22-hr treatments were replicated three times. In Experiment 3, hens were fed either ad libitum or feed was withheld the last 5 or 6 hr before oviposition. In Experiment 4, hens were fed 10 microCi of 45 Ca for 15 days to label skeletal calcium. Hens were divided into two groups and fed a .08 or 3.75% calcium diet for 2 days. On the second day, 25 hens fed the 3.75% calcium diet were intubated with 7 g of the same diet containing .5 g calcium at 1700, 2100, 0100, 0500, and 0700 hr. The measurements used were egg weight, shell weight, and 45 Ca content of the egg shell. Results indicated a significant linear or quadratic regression of dietary calcium levels on 45 Ca accumulation in eggshells and eggshell weight (Experiment 1). As the calcium level of the diet increased, eggshell weight increased and 45 Ca recovery decreased. Utilization of skeletal calcium for shell formation ranged from 28 to 96%. In Experiment 2, the rate of shell calcification was not constant throughout the calcification process but varied significantly

    Small for gestational age (SGA) children without catch-up growth can benefit from treatment with growth hormone (rhGH). However, they should be monitored very closely because they are at increased risk of metabolic syndrome. A group of 28 SGA children with a mean age of 8.79 years and undergoing treatment with rhGH were selected for evaluation. Over the course of 4 years, an annual evaluation was performed on the anthropometric variables (weight, height, body mass index [BMI], growth rate, blood pressure and waist perimeter), metabolic risk variables (glycaemia, glycosylated haemoglobin, cholesterol ratio, insulinaemia, insulin-like growth factor 1[IGF1], IGF binding protein-3 [IGFBP-3], IGF1/IGFBP3 ratio, and HOMA index), and body composition variables. Treatment with rhGH was associated with a significant increase in height (-2.76±.11 SD to -1.53±.17 SD, P=.000), weight (-1.50±.09 SD to -1.21±.13 SD; P=.016), and growth rate (-1.43±.35 SD to .41±.41 SD; P=.009), without a corresponding change in the BMI. Insulinaemia (9.33±1.93mU/ml to 16.55±1.72mU/ml; P=.044) and the HOMA index (3.63±.76 to 6.43±.67; P=.042) increased, approaching insulin resistance levels. No changes were observed in the lipid profile. Body composition changes were observed, with a significant increase in lean mass (73.19±1.26 to 78.74±1.31; P=.037), and a reduction of fat mass (26.81±1.26 to 21.26±1.31; P=.021). Treatment with rhGH is effective for improving anthropometric variables in SGA patients who have not experienced a catch-up growth. It also produces changes in body composition, which may lead to a reduction in risk of metabolic syndrome. However, some insulin resistance was observed. It is important to follow up this patient group in order to find out whether these changes persist into adulthood. Copyright © 2016 Asociación Española de Pediatría.

    Full Text Available Background. One third of Indian population is said to be suffering from chronic energy deficiency (CED, with increased risk of developing chronic diseases. A new anthropometric measure called A Body Shape Index (ABSI is said to be a better index in predicting risks for premature mortality. ABSI is also in part said to be a surrogate of visceral fat. Objective. The present study aimed to explore the association between indices of HRV (heart rate variability, BMI, WC, and ABSI in healthy Indian males with low BMI (BMI < 18.5 kg/m2 and to compare with normal BMI group (BMI 18.5 to 24.9 kg/m2. Methodology. ABSI and BMI were derived from anthropometric parameters, namely, height, weight, and waist circumference in 178 males aged 18 to 78 years. Subjects were categorized into two groups based on their BMI. Results and Conclusions. Power spectral analysis of HRV demonstrated a significant negative correlation between Log HF (high frequency and ABSI in both low BMI [−24.2 (9.4, P<0.05] and normal BMI group [−23.41 (10.1, P<0.05] even after controlling for age. Thus even with slight increase in BMI among low BMI individuals, there could be a greater risk of cardiovascular morbidity and mortality.

    To investigate the effects of ballet training on foot structure and the formation of the medial longitudinal arc in childhood, and the association of body mass index with structural change secondary to ballet training. This study was conducted at Öykü Ballet and Dance School and Trakya University, Edirne, Turkey, from September 2007 to November 2008, and comprised girl students who were taking ballet classes, and a group of those who were not taking such who acted as the controls. Static footprints of both feet of all participants were taken with an ink paedogram. Parameters evaluated from footprints included foot length, metatarsal width, heel width and medial longitudinal arch. The relationship between the parameters, the ballet starting age, training duration and body mass index was investigated. Of the 67 participants, there were 36(53.7%) in the experimental group and 31(48.3%) in the control group. The difference between age, height, weight and body mass index between the two groups was insignificant (p>0.05). The average ballet starting age was 6.47±1.55 years and duration was 4.36±2.002 years. Positive correlations were found between body mass index and foot length, metatarsal width, heel width, medial longitudinal arch contact width and halluxvalgus angle; between ballet starting age and metatarsal width, heel width; between duration of training and foot length, metatarsal width and hallux valgus angle (p?0.05 each). Evidence supporting the education in children on foot anthropometric measurements and medial longitudinal arc development could not be found.

    Ramadan fasting is believed to be beneficial. We assessed a random sample of 100 Egyptian male schizophrenia outpatients using the Positive and Negative Syndrome Scale (PANSS) and dietary, anthropometric, clinical, and laboratory measures at baseline (T1) before Ramadan of 2014 and during the fourth week of Ramadan (T2). The metabolic syndrome was identified in 31 patients and these showed a reduction of high-density lipoprotein cholesterol (HDLc) and brain-derived neurotrophic factor (BDNF) concentrations and increase in the levels of dietary intakes, body mass index (BMI), waste circumference, systolic and diastolic blood pressure, all PANSS subscales, glucose, insulin, HOMA-IR, total cholesterol, triglycerides, low-density lipoprotein-cholesterol (LDL-c), white blood cells, granulocytes, lymphocytes, monocytes, fibrinogen and high-sensitivity C-reactive protein (hs-CRP). In a multiple regression analysis, total energy intake and body mass index (BMI) emerged as the main independent predictors of deterioration in most inflammatory and psychopathology parameters. These findings did not support our hypothesis but suggested that Ramadan fasting has a negative impact on schizophrenia patients, especially those with metabolic syndrome. This could draw attention to the need in the psycho-education management of such patients to focus more on nutrition education for safe fasting. Copyright © 2014 Elsevier Ireland Ltd.

    To investigate factors associated with the response to ovarian stimulation in patients with polycystic ovary syndrome. Methods: The records of patients with polycystic ovary syndrome and infertility who underwent ovulation induction with clomiphene citrate were reviwed between January 2011 and December 2014 in Etlik Zübeyde Hanim Women's Health Training and Research Hospital Ankara, Turkey. The anthropometric and endocrine factors of patients who were resistant to treatment at a dose of 150 mg/day (n=84) were compared with those who responded with growth of at least one graaffian follicle at a dose of 50 mg/day (n=342). Results: Of the parameters examined, body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio were significantly higher in the clomiphene citrate-resistant group compared with the responsive group. Conclusion: Reproductive treatment in patients with polycystic ovary syndrome show different outcomes. Significantly higher body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio observed in clomiphene citrate resistant group can be a possible explanation for this impedance.

    Evaluate the effect of glycemic index (GI) on biochemical parameters, food intake, energy metabolism, anthropometric measures and body composition in overweight subjects. Simple blind study, in which nineteen subjects were randomly assigned to consume in the laboratory two daily low GI (n = 10) or high GI (n = 9) meals, for forty-five consecutive days. Habitual food intake was assessed at baseline. Food intake, anthropometric measures and body composition were assessed at each 15 days. Energy metabolism and biochemical parameters were evaluated at baseline and the end of the study. Low GI meals increased fat oxidation, and reduced waist circumference and HOMA-IR, while high GI meals increased daily dietary fiber and energy intake compared to baseline. There was a higher reduction on waist circumference and body fat, and a higher increase on postprandial fat oxidation in response to the LGI meals than after high GI meals. High GI meals increased fasting respiratory coefficient compared to baseline and low GI meals. The results of the present study showed that the consumption of two daily low GI meals for forty-five consecutive days has a positive effect on obesity control, whereas, the consumption of high GI meals result has the opposite effect.

    Neurotransmitters, neuropeptides and hormones are released through the regulated exocytosis of SVs (synaptic vesicles) and LDCVs (large dense-core vesicles), a process that is controlled by calcium. Synaptotagmins are a family of type 1 membrane proteins that share a common domain structure. Most....... Also, we discuss potential roles of synaptotagmins in non-traditional endocrine systems....... synaptotagmins are located in brain and endocrine cells, and some of these synaptotagmins bind to phospholipids and calcium at levels that trigger regulated exocytosis of SVs and LDCVs. This led to the proposed synaptotagmin-calcium-sensor paradigm, that is, members of the synaptotagmin family function...... as calcium sensors for the regulated exocytosis of neurotransmitters, neuropeptides and hormones.

Since then, the interest for calcium phosphates has increased among the scientific community. Their study has been developed in parallel with new advances in materials sciences, medicine or tissue engineering areas. Bone tissue engineering is the field where calcium phosphates have had a great importance. While the first bioceramics are selected according to bioinert, biocompatibility and mechanical properties with the aim to replace bone tissue damaged, calcium phosphates open the way to the bone tissue regeneration challenge. Nowadays, they are present in the majority of commercial products directed to repair or regenerate damaged bone tissue.

    Diabetes mellitus (DM) is becoming a lifestyle-related pandemic disease. Diabetic patients frequently develop electrolyte disorders, especially diabetic ketoacidosis or nonketotic hyperglycemic hyperosmolar syndrome. Such patients show characteristic potassium, magnesium, phosphate, and calcium depletion. In this review, we discuss a homeostatic mechanism that links calcium and DM. We also provide a synthesis of the evidence in favor or against this linking mechanism by presenting recent clinical indications, mainly from veterinary research. There are consistent results supporting the use of calcium and vitamin D supplementation to reduce the risk of DM. Clinical trials support a marginal reduction in circulating lipids, and some meta-analyses support an increase in insulin sensitivity, following vitamin D supplementation. This review provides an overview of the calcium and vitamin D disturbances occurring in DM and describes the underlying mechanisms. Such elucidation will help indicate potential pathophysiology-based precautionary and therapeutic approaches and contribute to lowering the incidence of DM.

    Gaspers, Lawrence D; Thomas, Andrew P

    2005-01-01

    In hepatocytes, hormones linked to the formation of the second messenger inositol 1,4,5-trisphosphate (InsP3) evoke transient increases or spikes in cytosolic free calcium ([Ca2+]i), that increase in frequency with the agonist concentration. These oscillatory Ca2+ signals are thought to transmit the information encoded in the extracellular stimulus to down-stream Ca2+-sensitive metabolic processes. We have utilized both confocal and wide field fluorescence microscopy techniques to study the InsP3-dependent signaling pathway at the cellular and subcellular levels in the intact perfused liver. Typically InsP3-dependent [Ca2+]i spikes manifest as Ca2+ waves that propagate throughout the entire cytoplasm and nucleus, and in the intact liver these [Ca2+]i increases are conveyed through gap junctions to encompass entire lobular units. The translobular movement of Ca2+ provides a means to coordinate the function of metabolic zones of the lobule and thus, liver function. In this article, we describe the characteristics of agonist-evoked [Ca2+]i signals in the liver and discuss possible mechanisms to explain the propagation of intercellular Ca2+ waves in the intact organ.

    1978-01-01

    In rats the relationships between EHDP-induced changes in serum calcium concentration, kidney calcium content and duodenal transport of 45 calcium were studied. Body weights and kidney weights were similar in all groups. EHDP administration was associated with an increase in serum calcium concentration and kidney calcium content, and a decrease in duodenal 45 calcium transport. In the EHDP-treated rats, there was a significant negative correlation between kidney calcium concentration and duodenal 45 calcium transport but no correlation between either kidney calcium content and serum calcium concentration (r = 0.116) or between serum calcium concentration and duodenal 45 calcium transport (r = 0.02). Further experiments will be needed to determine whether the demonstrated increase in kidney calcium content induced by EHDP administration was the cause of, or was secondary to, inhibition of 1, 25(OH) 2 D 3 synthesis.

    Full Text Available Mineral fertilizers are one of the important factors of agriculture intensification and increasing of food products quantity. The volume of fertilizers production and its domestic consumption in Ukraine indicate that nitrogen fertilizer using only comes nearer to the required number of science-based. One of the most widespread artificial fertilizers is the calcium nitrate. Aim: The aim is to study and theoretically substantiate the processes occurring in the preparation of suspensions of calcium hydroxide Са(ОН2 in solution of calcium nitrate Ca(NО32. Materials and Methods: The technical calcium oxide (quicklime DSTU BV.2.7-90-99, solutions of calcium nitrate of 15, 20, 25, 30, 35 and 40% Ca(NО32 concentrations were used in the work. The content of lime in the preparation of a suspension in the solution changed (in terms of calcium oxide CaO from 150 g/dm3 to the maximum possible. Each of these solutions saturated at 40°С in lime to maximum concentration. Suitable for use in these experiments and in the technology of calcium nitrate obtaining are considered the solutions (suspensions that within 12 hours did not lose their mobility (transportability. Results: The experimental results show that increasing of the concentration of calcium nitrate in solution within the range 15...40%, the amount of lime that you can put into the solution without loss of transportability decreases. Further increasing of lime quantity in solutions concentrations causes to its solidifying, loss of mobility (transportability. Calculations showed that in the presence of calcium nitrate the solubility of Са(ОН2 is reduced nearly by order that can lead to the formation of calcium oxide CaO the solid phase Са(ОН2 on the surface, which also can form hydrogen bonds with the components of the solution. As the probability of formation of hydrogen bonds in solutions is high, there is a possibility of formation of clusters.

    Full Text Available In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are a bioactive and biodegradable grafting material in the form of a powder and a liquid. Both phases form after mixing a viscous paste that after being implanted, sets and hardens within the body as either a non-stoichiometric calcium deficient hydroxyapatite (CDHA or brushite, sometimes blended with unreacted particles and other phases. As both CDHA and brushite are remarkably biocompartible and bioresorbable (therefore, in vivo they can be replaced with newly forming bone, calcium orthophosphate cements represent a good correction technique for non-weight-bearing bone fractures or defects and appear to be very promising materials for bone grafting applications. Besides, these cements possess an excellent osteoconductivity, molding capabilities and easy manipulation. Furthermore, reinforced cement formulations are available, which in a certain sense might be described as calcium orthophosphate concretes. The concepts established by calcium orthophosphate cement pioneers in the early 1980s were used as a platform to initiate a new generation of bone substitute materials for commercialization. Since then, advances have been made in the composition, performance and manufacturing; several beneficial formulations have already been introduced as a result. Many other compositions are in experimental stages. In this review, an insight into calcium orthophosphate cements and concretes, as excellent biomaterials suitable for both dental and bone grafting application, has been provided.

    To standardize the calibration methods of whole-body counters, three anthropometric phantoms were manufactured based on dozens of Japanese average value of body size data. Using these phantoms, the calibrations of some whole-body counters were carried out and the comparison of counting efficiency between anthropometric phantoms and block phantoms, which used to be used for the calibration of whole-body counters generally, was implemented. Five whole-body counters, one scanning system, two stationary systems and two chair systems, were used for this study. The following results were derived: As an example, in NIRS scanning system, the counting efficiency of anthropometric phantom of 162cm height was 12.7% greater than that of block phantom of the same height. This means 137 Cs body burdens in adult men used to be estimated with the excess of about 10%. Body burdens tended to be estimated excessively in adult because the difference of counting efficiency between anthropometric phantom and block phantom increases with increase of height. To standardize body burden data measured with various whole-body counters, the calibration of each whole-body counter should be conducted using anthropometric phantoms and phantoms which used to be used for the calibration of that whole-body counter.

    Full Text Available Physical factors and health and safety issues and training are the most effective and most fundamental natural growth factor in terms of physical, mental and educational development in students. This study was designed to obtain anthropometric dimensions of Iranian primary school student. We searched international databases such as Thomson Reuters, PubMed, Scopus, EMBASE, Cochrane Library, and Iranian databases such as SID, Magiran, Iranmedex using a searching strategy during 2000 to 2016 years. Database without language restriction, since 2000 sources, with the MeSH term "Anthropometric data" AND "Iranian primary school children". At first, in the initial search,115 articles were found, and finally, 22 of them which were related to the subject of this research were used. This study showed significant differences in a set of anthropometric dimensions with regard to gender, age and ethnicity.Alsothis study indicates that there is a significant difference between the minimum and maximum acceptable dimensions and those of the available furniture (p < 0.05.According to the results of this study, difference between genders and among different ethnicities should be taken into account by designers and manufacturers of school furniture. In many schools, there is not proportion between students’ anthropometric dimensions and the dimensions of existing tables and benches. Thus, it is suggested that required efforts are done to design educational furniture such as table and bench for various grades of elementary level in every region according to the existing anthropometric dimensions database.

    To investigate the intakes of dietary calcium/dairy and the current prevalence of overweight and obesity among children and adolescents aged 7-15 in Longquanyi District, Chengdu, and to explore the association of dietary calcium and dairy intake with overweight/obesity. 1738 children and adolescents were recruited in the cross-sectional study using cluster random sampling method. Information on dietary calcium and dairy intakes was collected using 24-hour dietary recall and food frequency questionnaire (FFQ). Height, weight and waist circumference were measured to calculate body mass index (BMI)/waist-to-height ratio (WHtR) and body mass index standard deviation (BMI SDS). Overweight/obesity was defined based on the criteria of Working Group on Obesity in China (WGOC). Participants were grouped into 3 categories indicating lower, moderate and higher intakes of dietary calcium and dairy, respectively. The association of dietary calcium and dairy consumption with (BMI SDS) /WHtR and the prevalence of overweight/obesity was analyzed after being stratified by gender and age. The prevalence of overweight/obesity in boys and girls were 11.92%/7.04% and 8.04%/6.30%, respectively. The intake of dietary calcium and dairy in girls were much higher than that in boys (P obesity in boys, however the associations were inconsistent among different age groups. Associations between consumption of calcium, dairy and overweight/obesity were not found among girls.

    Full Text Available To study the effects of calcium superphosphate additive on nitrogen conservation, an experiment of 30 days dead-pig composting was carried out. Three mixtures were treated with different amount of calcium superphosphate additive of 0%(CK, 5%(T1 and 10%(T2. The results showed that each composte temperature higher than 50 ℃ remained above 10 days, meeting the requirements of hygiene index about the compost rotten. The pH of composting with calcium superphosphate was significantly decreased, while NH4+-N, NH3-N, total nitrogen contents were significant higher than the control. 5% and 10% calcium superphosphate addition increased the total nitrogen contents by 10.7%, 10.1%, respectively. The seed germination index(GI of 5% calcium superphosphate addition was up to 101.4% on the 14th day, which was significant higher than the contrast. It demonstrated that calcium superphosphate could accelerate maturity during dead-pig compositng. Thus, calcium superphosphate as an additive in dead-pig composting could decrease nitrogen losses, which would bring prospects of application in dead-pig composting.

    To assess the conformity of the weight measurement process in the pre-gestational care offered in the city of Rio de Janeiro by primary units and hospitals of the National Health System, as well as to verify the agreement between the anthropometric data reported by pregnant women and those recorded in prenatal cards. A cross-sectional study was conducted in 2007 - 2008 with two cluster samples: one to obtain a sample of pregnant women to be interviewed and another one for the weight measurement procedures to be observed. The conformity of the weight measurement process was evaluated according to the Ministry of Health standards, and the agreement between the two sources of anthropometric data was evaluated using mean differences, Bland-Altman method, intraclass correlation coefficient (ICC) and weighted Kappa. Out of the twelve criteria for weight measurement evaluation (n = 159 observations), three weren't in conformity (conformity), two of them only need to be assessed when the scale is mechanical. For the interviewed pregnant women (n = 2,148), who had the two sources of anthropometric data, there was a tendency of self-reported height overestimation and pre-gestational and current weight and Body Mass Index underestimation. Accordance between the two sources of anthropometric information, according to ICC and weighted Kappa, were high (> 0.80). Studies may use weight and height information reported by pregnant women, in the absence of prenatal cards records, when it is an important economy to their execution, although the improvement of these two sources of information by means of better anthropometric process is necessary.

    Dietary calcium and vitamin D are essential for bone development. Apart from diet, physical activity may potentially improve and sustain bone health. To investigate the relationship between the dietary intake of calcium and vitamin D, physical activity, and bone mineral content (BMC) in 13-year-old Malaysian adolescents. Cross-sectional. Selected public secondary schools from the central and northern regions of Peninsular Malaysia. The subjects were from the Malaysian Health and Adolescents Longitudinal Research Team Cohort study (MyHeARTs). The data included seven-day diet histories, anthropometric measurements, and the BMC of calcaneal bone using a portable broadband ultrasound bone densitometer. Nutritionist Pro software was used to calculate the dietary calcium and vitamin D intakes from the diet histories, based on the Nutrient Composition of Malaysian Food Database guidance for the dietary calcium intake and the Singapore Energy and Nutrient Composition of Food Database for vitamin D intake. A total of 289 adolescents (65.7% females) were recruited. The average dietary intakes of calcium and vitamin D were 377 ± 12 mg/day and 2.51 ± 0.12 µg/day, respectively, with the majority of subjects failing to meet the Recommended Nutrient Intake (RNI) of Malaysia for dietary calcium and vitamin D. All the subjects had a normal Z-score for the BMC (-2.00 or higher) with a mean of 0.55 ± 0.01. From the statistical analysis of the factors contributing to BMC, it was found that for those subjects with a higher intake of vitamin D, a higher combination of the intake of vitamin D and calcium resulted in significantly higher BMC quartiles. The regression analysis showed that the BMC might have been influenced by the vitamin D intake. A combination of the intake of vitamin D and calcium is positively associated with the BMC.

    Calcium carries messages to virtually all important functions of cells. Although it was already active in unicellular organisms, its role became universally important after the transition to multicellular life. In this Minireview, we explore how calcium ended up in this privileged position. Most likely its unique coordination chemistry was a decisive factor as it makes its binding by complex molecules particularly easy even in the presence of large excesses of other cations, e.g. magnesium. Its free concentration within cells can thus be maintained at the very low levels demanded by the signaling function. A large cadre of proteins has evolved to bind or transport calcium. They all contribute to buffer it within cells, but a number of them also decode its message for the benefit of the target. The most important of these “calcium sensors” are the EF-hand proteins. Calcium is an ambivalent messenger. Although essential to the correct functioning of cell processes, if not carefully controlled spatially and temporally within cells, it generates variously severe cell dysfunctions, and even cell death.

    The objective of this study was to provide anthropometric, physiological, and performance characteristics of an elite international handball team. Twenty-one elite handball players were tested and categorized according to their playing positions (goalkeepers, backs, pivots, and wings). Testing consisted of anthropometric and physiological measures of height, body mass, percentage body fat and endurance (VO(2max)), performance measures of speed (5, 10, and 30 m), strength (bench press and squat), unilateral and bilateral horizontal jumping ability, and a 5-jump horizontal test. Significant differences were found between player positions for some anthropometric characteristics (height and percentage body fat) but not for the physiological or performance characteristics. Strong correlations were noted between single leg horizontal jumping distances with 5-, 10-, and 30-m sprint times (r = 0.51-0.80; P team-handball players appear to be very similar. Single leg horizontal jumping distance could be a specific standardized test for predicting sprinting ability in elite handball players.

    Experiments were conducted in a thermogravimetric analyzer to investigate thermal behavior of different organic calcium compounds (OCCs) and its blended fuels with three kinds of biomass. The effectiveness of synthesized method for OCC was assessed by the pyrolysis test. Effect of the mole ratio of calcium to sulfur on co-combustion characteristics was studied. Results indicated that preparation method of modified calcium acetate (MCA) had high precision and accuracy. Co-combustion characteristic of OCCs blended with biomass was controlled by OCCs' additive amount and the content of volatile matter which is mainly composed of small hydrocarbon molecules. Combustion performance indexes for peanut shell and wheat straw impregnated by OCCs were improved, however, an inverse trend was found for rice husk because of lower additive amount of OCCs. The blended fuel show higher combustion performance indexes compared with combustion of individual biomass, and these indexes decrease with increases of Ca/S ratio. Copyright © 2014 Elsevier Ltd.

    This study was carried out with the objective to obtain the anthropometric data of primary school children from Year 1 to Year 6 and evaluate the children's anthropometry with the current dimensions of classroom furniture (i.e. chair and table). In addition, this study also proposed the design dimensions for the improvement in classroom furniture design with the consideration of children's anthropometric data. A total of 390 children selected from 13 primary schools in Perlis, Malaysia were participated in this study. There were 11 anthropometric measurements of children have been measured in this study, which include stature (St), popliteal height (PH), knee height (KH), thigh thickness (TT), buttock popliteal length (BPL), hip breadth (HB), sitting shoulder height (SSH), sitting elbow height (SEH), forearm-hand length (FHL), height of lumbar point (HLP) and buttock clearance (BC). Besides that, 7 dimensions relating to current classroom chair have been measured, such as seat height (SH), seat depth (SD), seat width (SW), upper edge of backrest (UEB), lower edge of backrest (LEB), S point (SP), overall chair height (OCH). Another 5 dimensions of the existing classroom table have been measured too, which involve table height (TH), table depth (TD), table width (TW), under table height (UH) and seat to table clearance (STC). All the measurements were performed by using metal measuring tape. The anthropometric data of the children were analyzed with the help of Microsoft Excel 2013. Several equations with associated with the anthropometric data and furniture dimensions have been applied in this research. The new design dimensions for classroom furniture that proposed in this paper which based on the collected anthropometric data can be referred as a guideline for classroom furniture design. The implementation of these data may help to create comfortability, safety, suitability and improve performance of children in the classroom.

    Full Text Available Background: Anthropometry is a branch of Ergonomics that considers the measurement and description of the human body dimensions. Accordingly, equipment, environments, and workstations should be designed using user-centered design processes. Anthropometric dimensions differ considerably across gender, race, ethnicity and age, taking into account ergonomic and anthropometric principles. The aim of this study was to determine anthropometric characteristics of microscope users and provide a regression model for anthropometric dimensions. Methods: In this cross-sectional study, anthropometric dimensions (18 dimensions of the microscope users (N=174; 78 males and 96 females in Shiraz were measured. Instruments included a Studio meter, 2 type calipers, adjustable seats, a 40-cm ruler, a tape measure, and scales. The study data were analyzed using SPSS, version 20. Results: The means of male and female microscope users’ age were 31.64±8.86 and 35±10.9 years, respectively and their height were 161.03±6.87cm and 174.81±5.45cm, respectively. The results showed that sitting and standing eye height and sitting horizontal range of accessibility had a significant correlation with stature. Conclusion: The established anthropometric database can be used as a source for designing workstations for working with microscopes in this group of users. The regression analysis showed that three dimensions, i.e. standing eye height, sitting eye height, and horizontal range of accessibility sitting had a significant correlation with stature. Therefore, given one’s stature, these dimensions can be obtained with less measurement.

Aim of the research : To analyse the relationship between calcium consumption and body composition of the participants of this study. Material and methods : The study was carried out on a sample group of 103 nursing students. The study group consisted of 91 (88.3% women and 12 (11.7% men, aged from 19 to 33 years. The participants of the study had their body composition analysed, the body mass index (BMI was calculated, and the authors carried out a survey involving the Dairy Products Frequency Questionnaire (ADOS-Ca as well as their own questionnaire to evaluate the socio-economic status of the subjects. Results : The students who had the lowest calcium consumption also had the lowest BMI (p = 0.0015 and the lowest amount of visceral fat (p = 0.0260. Individuals who consumed the lowest amount of calcium also had the lowest muscle mass (p = 0.007 and bone mass (p = 0.004. However, the authors did not notice a significant statistical difference between the level of calcium consumption and the percentage of adipose tissue (p = 0.5000 as well as body water percentage (p = 0.3200. Conclusions: The results of the research do not confirm the hypothesis that high calcium consumption is associated with a lower probability of the occurrence of excess body mass and adipose tissue.
