Anthropometric data for describing the kinematics of the human hand  

Microsoft Academic Search

The major goal of this investigation was to collect statistically-based anthropometry describing the kinematics of the human hand and to model this anthropometry as a function of external hand measurements, so that it may be predicted noninvasively. Joint centres were anatomically estimated as the centre of curvature of the head of the bone proximal to the given joint. Joint centres

Obesity and Myelomeningocele: Anthropometric Measures  

PubMed Central

Objective: To evaluate the appropriate use of arm span measurements as a substitute for height/linear length to evaluate obesity in people with myelomeningocele by comparing calculated body mass indices (BMIs) with recently published BMI graphs by the Centers for Disease Control and Prevention (CDC) and National Center for Health Statistics standards (NCHS) published in 2000. Study Design: Retrospective analysis of collected data on patients seen in the University of Washington Birth Defects Clinic from July 1, 1965, through June 1, 2008. Observations included degree of paralysis, presence of scoliosis, height (linear length), weight, and arm span. We compared published CDC/NCHS BMIs with our data using both height and arm span in place of height/linear length. There were 14,701 measures collected during 4,968 visits from 709 patients. Mean values were calculated using age, gender, and lesion level as independent variables. Results: Comparison of BMI means of patients with myelomeningocele suggests that our observations using arm span and height are comparable with the CDC/NCHS BMI means using height for the 2 least paralyzed groups but not for those groups with paralysis from high-level lesions that are more likely to exhibit lower extremity deformities or scoliosis. Conclusions: Published CDC/NCHS graphs, with their percentiles, are appropriate for estimating normal growth by BMI for children born with myelomeningocele when arm span is substituted for length if severe body differences due to high-level paralysis are taken into consideration.

Correlations of Handgrip Strength with Selected Hand-Arm-Anthropometric Variables in Indian Inter-university Female Volleyball Players  

PubMed Central

Purpose The purpose of this study was to estimate the dominant handgrip strength and its correlations with some hand and arm anthropometric variables in 101 randomly selected Indian inter-university female volleyball players aged 18-25 years (mean age 20.52±1.40) from six Indian universities. Methods Three anthropometric variables, i.e. height, weight, BMI, two hand anthropometric variables, viz. right and left hand width and length, four arm anthropometric variables, i.e. upper arm length, lower arm length, upper extremity length, upper arm circumference and dominant right and non-dominant handgrip strength were measured among Indian inter-university female volleyball players by standard anthropometric techniques. Results The findings of the present study indicated that Indian female volleyball players had higher mean values in eleven variables and lesser mean values in two variables than their control counterparts, showing significant differences (P<0.032-0.001) in height (t=2.63), weight (t=8.66), left hand width (t=2.10), left and right hand length (t=9.99 and 10.40 respectively), right upper arm length (t=8.48), right forearm length (t=5.41), dominant (right) and non-dominant (left) handgrip strength (t=9.37 and 6.76 respectively). In female volleyball players, dominant handgrip strength had significantly positive correlations (P=0.01) with all the variables studied. Conclusion It may be concluded that dominant handgrip strength had strong positive correlations with all the variables studied in Indian inter-university female volleyball players.

Anthropometric measurements as predictors of intraabdominal fat thickness.  

PubMed

Central obesity is known to be an important risk factor in the development of metabolic syndrome and intraabdominal fat thickness has been found to be a reliable indicator of central obesity. Many anthropometric indicators have been suggested for measuring intraabdominal fat. The aim of this study was to relate various anthropometric measurements to intraabdominal fat thickness and to determine which among these is a better predictor of intra abdominal fat in normal subjects. This cross sectional study was carried out. in 60 healthy subjects (32 males and 28 females) in the age group of 25-55 years. Anthropometric measurements such as BMI, waist circumference and waist-hip ratio were assessed by using standard methods. Subcutaneous and visceral fat were measured 1 cm above umbilicus by ultrasonography. Intraabdominal fat thickness was correlated with the anthropometric measures by Pearson's test. Multivariate linear regression test was used to find the best anthropometric measurement as a predictor of abdominal fat. Waist circumference showed a significant positive correlation with subcutaneous fat and visceral fat. Waist circumference was found to be the best predictor of intraabdominal fat thickness in normal subjects and therefore of central obesity. PMID:20329373

Impact of anthropometric measurements in clinical practice.  

PubMed

Anthropometry helps to assess nutritional status which is an important determinant of clinical outcome in many patients, including the number of those suffering from chronic kidney disease (CKD). Weight gain after successful kidney transplantation is a well-known phenomenon, therefore we hypothesized that intensive counseling, based of menu analysis by a dietitian of CKD patients with a kidney transplant, can prevent the significant body weight (BW) gain after the transplant operation. The aim of the investigation was to study long-term anthropometrical, biochemical and dual-energy densitometry changes in the kidney transplant patients, to study correlations between the studied parameters and to compare those with the follow-up data. The prospective long-term study was carried out in 28 clinically stable renal transplant patients. Control groups consisted both transplant patients (47 patients), receiving ordinary nutritional counseling, and of healthy population subjects (342). Anthropometry and biochemistry were studied in patients twice: the first follow-up (FU1) data were collected 1.3 +/- 0.2 years, and the second follow-up (FU2) data were collected 2.7 +/- 0.3 years after the transplant. Significant BW gain was found only in renal transplant male patients (FU1 vs. FU2, p < 0.001) but not in females. The mean weight gain in control group patients was significant both in the male and female groups. In males, the mean C-reactive protein was significantly correlated with different body circumferences. But, in females, no clear associations were found. In females, significant correlation was found between mean body weight, body mass index and triglycerides. We conclude that the use of anthropometry in clinical practice, together with intensive and individual counseling by a dietitian, should be regular in the kidney transplant patients' population to prevent overweight. Monitoring of the dynamics of anthropometrical and biochemical parameters are clinically relevant in the post-transplant period together with densitometry. PMID:23390829

Neck Circumference as an Anthropometric Measure of Obesity in Diabetics  

PubMed Central

Background: Obesity is a risk factor for type 2 diabetes mellitus. Insulin resistance is associated with visceral subcutaneous fat content. Neck circumference (NC) is a marker of upper body subcutaneous adipose tissue distribution. Aim: The aim of this study is to compare NC in diabetics and non-diabetics and to correlate NC with other anthropometric measures. Materials and Methods: A cross-sectional study was conducted in 350 type 2 diabetics and 350 non-diabetics of >30 years of age. Anthropometric parameters like body mass index (BMI), waist circumference (WC), hip circumference, and NC were measured. Independent t-test and Pearson's correlation were the tests of significance done to analyze quantitative data. Results: There was positive correlation of NC, BMI, and index of central obesity. The NC in diabetics was significantly higher than in non-diabetics (P < 0.001). NC >36 cm in diabetics and >37 cm in non-diabetics was the best cutoff value to determine subjects with central obesity. Conclusion: The findings indicated that NC may be used both in clinical practice and in epidemiologic studies as a straightforward and reliable index. It is an economical easy to use test with less consumption of time and correlates well with other standard anthropometric parameters.

Anthropometric measures and nutritional status in a healthy elderly population  

PubMed Central

Background Anthropometric evaluation is an essential feature of geriatric nutritional evaluation for determining malnutrition, being overweight, obesity, muscular mass loss, fat mass gain and adipose tissue redistribution. Anthropometric indicators are used to evaluate the prognosis of chronic and acute diseases, and to guide medical intervention in the elderly. We evaluated anthropometric measurements and nutritional status as they relate to age and gender in healthy elderly people. Methods The study analyzed data from the national survey "Health needs and health service use by older-than-60-year-old beneficiaries of the Mexican Institute of Social Security (IMSS)". The present study included only individuals who reported no chronic disease in the last 20 years and had no hospital admission in the two months prior to the survey. Anthropometric measurements included weight, height, body mass index (BMI), body circumference (arm, waist, hip and calf), waist to hip ratio (WHR), elbow amplitude and knee-heel length. Results Application of the inclusion criteria resulted in a study population elderly of 1,968, representing 12.2% of the original number in the national survey in urban areas beneficiaries of the IMSS. The study population comprised 870 women and 1,098 men, with a mean age of 68.6 years. The average weights were 62.7 kg for women and 70.3 kg for men (p < 0.05), and the mean heights were 1.52 m for women and 1.63 m for men (p < 0.05). Age related changes in anthropometric values were identified. BMI values indicated that 62.3% of the population was overweight, and 73.6% of women and 16.5% of men had high fat tissue distribution. Conclusion Our findings suggest that applying the BMI thresholds that identify being overweight in the general adult population may lead to an overestimation in the number of overweight elderly Similar problems appear to exist when assessing waist circumference and WHR values. Prospective studies are required to determine the associations between health and BMI, waist circumference and WHR in the elderly.

Quantitative evaluation of the orofacial morphology: anthropometric measurements in healthy and mouth-breathing children.  

PubMed

The anthropometric orofacial measurements of mouth-breathing children were compared to those of children with no history of speech-language disorders, according to age. Methods: 100 children participated, both males and females, with ages ranging from 7 to 11 years and 11 months, leukoderm, in mixed dentition period, with a mouth-breathing diagnosis. The control group was comprised of 254 children, of both sexes, with ages ranging from 7 to 11 years and 11 months, leukoderm, in mixed dentition period, with no history of speech-language disorders. The control group did not demonstrate any mouth-breathing. The children were submitted to anthropometric assessment and the orofacial measurements obtained were upper lip, lower lip, philtrum, upper face, middle face, lower face, and sides of the face. The instrument used was the electronic digital sliding caliper Starrett Series 727. There was statistically significant difference between the majority of the orofacial measurements of mouth-breathing children and the measurements of children with no history of speech-language disorders. Some orofacial measurements were different in the studied populations. The possibility of comparing orofacial measurements of children with and without mouth-breathing behavior allows the clinician to determine normal and altered structures of the orofacial morphology. The main advantages of the anthropometry are its noninvasive nature, its technological simplicity, low cost and objective analysis. The anthropometric procedures also have clinical applications in myofunctional assessment and therapy. PMID:20572437

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 automatic 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 proposed system.

Environmental factors associated with preschool obesity. III. Dietary intakes, eating patterns, and anthropometric measurements.  

PubMed

This longitudinal study of children from six months to six years of age showed differences by age, sex, and race in dietary intakes, eating patterns, and anthropometric measurements. Except for calories and iron at all ages and calcium between two and four years, most children consumed at least two-thirds of the Recommended Dietary Allowances. Dietary protein was consistently high at all ages. There was no apparent relationship between the use and need for vitamin or mineral supplements. At six years of age, most children ate five meals or snacks per day. Television commercials, children accompanying mothers to grocery stores, and the publicized relationships of dietary fat and cholesterol to coronary disease influenced food practices of families. Anthropometric measurements revealed that boys were consistently taller and heavier than girls. However, at all ages, even at six months, girls had higher skinfold values than boys. These data on dietary intakes, eating practices, and anthropometric measurements will be correlated with obesity indexes at each age in subsequent papers. PMID:670612

Normative Findings for Periocular Anthropometric Measurements among Chinese Young Adults in Hong Kong  

PubMed Central

Measurement of periocular structures is of value in several clinical specialties including ophthalmology, optometry, medical and clinical genetics, oculoplastic surgery, and traumatology. Therefore we aimed to determine the periocular anthropometric norms for Chinese young adults using a noninvasive 3D stereophotography system. Craniofacial images using the 3dMDface system were acquired for 103 Chinese subjects (51 males and 52 females) between the ages of 18 and 35 years. Anthropometric landmarks were identified on these digital images according to standard definitions, and linear distances between these landmarks were calculated. It was found that ocular measurements were significantly larger in Chinese males than females for intercanthal width, biocular width, and eye fissure lengths. No gender differences were found in the eye fissure height and the canthal index which ranged between 43 and 44. Both right and left eye fissure height-length ratios were significantly larger in females. This is the first study to employ 3D stereophotogrammetry to create a database of anthropometric normative data for periocular measurements. These data would be useful for clinical interpretation of periocular pathology and serve as reference values when planning aesthetic and posttraumatic surgical interventions.

Effect of Workplace-Visiting Nutrition Education on Anthropometric and Clinical Measures in Male Workers  

PubMed Central

The purpose of this study was to investigate effect of nutrition education at worksite program in male workers. The subjects were 75 male workers who had received nutrition education by a clinical dietitian for 4 months. The anthropometric data, blood pressure and biochemical blood indices were measured before and after nutrition education. Dietary habits and lifestyle were investigated by self-administered questionnaires. Nutrients intake was determined by 24-hour dietary recall method. The results showed significant decreases in body mass index (p < 0.05), fasting blood sugar (p < 0.01), total cholesterol (p < 0.05), and LDL-cholesterol (p < 0.05) after nutrition education. The correlation analyses among anthropometric and clinical parameters after nutrition education indicated that there was a significantly positive correlations between blood pressure and weight, r-GTP. A significantly positive correlations was observed between fasting blood sugar and triglycerides. A significantly positive correlations was observed between triglycerides and body mass index, r-GTP, SGPT. A significantly positive correlations was observed between SGPT and weight, body mass index. A significantly negative correlations was observed between HDL-cholesterol and weight. It could be concluded that nutrition education might be effective tool to improve anthropometric measures and clinical parameters in male workers. Continuing and systematic nutritional management programs should be developed and implemented for male workers at the worksites to maintain optimal health status.

Abdominal fat sonographic measurement compared to anthropometric indices for predicting the presence of coronary artery disease.  

PubMed

Objectives- Sonography for measuring intra-abdominal fat is more accurate than anthropometric measurements. Computed tomographic (CT) angiography has become an accurate noninvasive method for detection of coronary artery disease (CAD). We examined the associations between both sonographic and anthropometric measurements of abdominal adiposity and the presence of CAD on CT angiography. Methods- We evaluated 83 consecutive patients (70% men; mean age ± SD, 56 ± 10.8 years) who were referred for CT angiography. Clinical and laboratory variables were determined, and CT angiography was performed using a 64-slice scanner. The severity of CAD was defined by visual assessment of any plaque, either calcified or noncalcified. Preperitoneal fat, subcutaneous fat, and visceral fat thicknesses were determined on sonography, and the abdominal fat index was calculated as the preperitoneal fat thickness-to-subcutaneous fat thickness ratio. Results- Coronary artery disease was detected in 56 patients (67%). Patients with CAD had higher visceral fat thickness (9.3 ± 2.0 versus 8.2 ± 2.2 cm; P = .035) and a higher waist-to-hip ratio (0.97 ± 0.07 versus 0.92 ± 0.07; P = .018) than those without CAD. The preperitoneal fat thickness, subcutaneous fat thickness, and abdominal fat index were not correlated with the CAD status. After adjusting for traditional cardiovascular risk factors, however, only a waist-to-hip ratio higher than 0.95 remained significantly associated with the presence of CAD (odds ratio, 4.03; 95% confidence interval, 1.2-13.4). Conclusions- This study shows that sonographically based obesity measurements are not superior to anthropometric indices in predicting the presence of CAD. PMID:24154900

Comparison of a novel surface laser scanning anthropometric technique to traditional methods for facial parameter measurements.  

PubMed

This study was designed to determine if three-dimensional (3D) laser scanning techniques could be used to collect accurate anthropometric measurements, compared with traditional methods. The use of an alternative 3D method would allow for quick collection of data that could be used to change the parameters used for facepiece design, improving fit and protection for a wider variety of faces. In our study, 10 facial dimensions were collected using both the traditional calipers and tape method and a Konica-Minolta Vivid9i laser scanner. Scans were combined using RapidForm XOR software to create a single complete facial geometry of the subject as a triangulated surface with an associated texture image from which to obtain measurements. A paired t-test was performed on subject means in each measurement by method. Nine subjects were used in this study: five males (one African-American and four Caucasian females) and four females displaying a range of facial dimensions. Five measurements showed significant differences (p<0.05), with most accounted for by subject movements or amended by scanning technique modifications. Laser scanning measurements showed high precision and accuracy when compared with traditional methods. Significant differences found can be very small changes in measurements and are unlikely to present a practical difference. The laser scanning technique demonstrated reliable and quick anthropometric data collection for use in future projects in redesigning respirators. PMID:22214207

Correlation of epicardial fat and anthropometric measurements in Asian-Indians: A community based study  

PubMed Central

BACKGROUND: It is increasingly evident that visceral adipose tissue plays a leading role in the pathogenesis of the metabolic syndrome. Unfortunately, accurate quantification of intra-abdominal visceral fat is cumbersome and expensive. Epicardial fat represents the component of visceral fat distributed around the heart, and is readily and non-invasively assessed by echocardiography. AIMS: To determine the correlation of epicardial fat with anthropometric parameters in a healthy population of Asian-Indians. MATERIALS AND METHODS: A prospective, cross-sectional study was conducted as part of a community outreach program from December to March 2011. Individuals over 18 years of age were included in the study. Anthropometric data was collected for all patients. Epicardial fat was assessed in parasternal long and short axes. RESULTS: 350 healthy individuals were included in the study. Of them, 66.7% were males. Mean age was 42.7 ± 15.3 years (range 18-84). Mean body-mass index (BMI) and waist circumference were 23.3 ± 4.5 kg/m2 (range 15.2-34.3) and 80.2 ± 13.3 cm (range 43-115) respectively. Mean epicardial fat in both axes was 2.6 ± 1.3 mm (range 0.3-7.0). Epicardial fat measured in both axes correlated well with weight (r = 0.399, P < 0.001), waist circumference (r = 0.522, P < 0.001) and BMI (r = 0.471, P < 0.001). Epicardial fat also correlated with age (r = 0.559, P < 0.001). CONCLUSIONS: There is an excellent correlation between epicardial fat measured by echocardiography and anthropometric parameters of metabolic syndrome.

Combination with Anthropometric Measurements and MQSGA to Assess Nutritional Status in Chinese Hemodialysis Population  

PubMed Central

Aims: To assess the nutritional status, combination with anthropometric measurements and modified quantitative subjective global assessment (MQSGA) was used in multi-center hemodialysis population in South China. Methods: A cross-sectional, descriptive-analytic study was performed in 4 teaching hospitals in South China, dated from January 2010 to December 2011. Nutritional status was assessed with MQSGA and related anthropometric indexes. Serum albumin and transthyretin were also determined for nutritional assessment. Results: Eighty-two randomly selected hemodialysis patients participated in the nutritional assessment, of which 75 hemodialysis patients completed all assessments. The average age was 62.70 ± 14.21 years. The mean duration of hemodialysis was 3.29 ± 1.08 years. Of the included patients, 32% patients were well nourished, 60% were mild to moderately malnourished, and 8% were severely malnourished. Along with the malnutrition severity, the serum transthyretin significantly decreased. However, no obvious changes were found in serum albumin. The mean value (Mean ± SD; 25.78 ± 4.09 cm) of mid arm circumference (MAC) was negatively correlated with MQSGA (r = -0.365; P = 0.002). Body mass index (BMI) (Mean ± SD; 21.6 ± 3.1 kg/m2) was also significantly negatively correlated with MQSGA (r = -0.392; P = 0.001). The areas under the receiver operating characteristic curve were 0.664 and 0.726, respectively. Conclusions: Malnutrition is very common in South China hemodialysis population. Both BMI and MAC were effective markers for assessing nutritional status.

The influence of anthropometric factors on postural balance: the relationship between body composition and posturographic measurements in young adults  

PubMed Central

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.

Predicting Football Players' Dual-Energy X-Ray Absorptiometry Body Composition Using Standard Anthropometric Measures  

PubMed Central

Context: The recent increase in athlete size, particularly in football athletes of all levels, coupled with the increased health risk associated with obesity warrants continued monitoring of body composition from a health perspective in this population. Equations developed to predict percentage of body fat (%Fat) have been shown to be population specific and might not be accurate for football athletes. Objective: To develop multiple regression equations using standard anthropometric measurements to estimate dual-energy x-ray absorptiometry %Fat (DEXA%Fat) in collegiate football players. Design: Controlled laboratory study. Patients and Other Participants: One hundred fifty-seven National Collegiate Athletic Association Division IA football athletes (age ?=? 20 ± 1 years, height ?=? 185.6 ± 6.5 cm, mass ?=? 103.1 ± 20.4 kg, DEXA%Fat ?=? 19.5 ± 9.1%) participated. Main Outcome Measure(s): Participants had the following measures: (1) body composition testing with dual-energy x-ray absorptiometry; (2) skinfold measurements in millimeters, including chest, triceps, subscapular, midaxillary, suprailiac, abdominal (SFAB), and thigh; and (3) standard circumference measurements in centimeters, including ankle, calf, thigh, hip (AHIP), waist, umbilical (AUMB), chest, wrist, forearm, arm, and neck. Regression analysis and fit statistics were used to determine the relationship between DEXA%Fat and each skinfold thickness, sum of all skinfold measures (SFSUM), and individual circumference measures. Results: Statistical analysis resulted in the development of 3 equations to predict DEXA%Fat: model 1, (0.178 • AHIP) + (0.097 • AUMB) + (0.089 • SFSUM) ? 19.641; model 2, (0.193 • AHIP) + (0.133 • AUMB) + (0.371 • SFAB) ? 23.0523; and model 3, (0.132 • SFSUM) + 3.530. The R2 values were 0.94 for model 1, 0.93 for model 2, and 0.91 for model 3 (for all, P < .001). Conclusions: The equations developed provide an accurate way to assess DEXA%Fat in collegiate football players using standard anthropometric measures so athletic trainers and coaches can monitor these athletes at increased health risk due to increased size.

The relationship between DXA-based and anthropometric measures of visceral fat and morbidity in women  

PubMed Central

Background Excess accumulation of visceral fat is a prominent risk factor for cardiovascular and metabolic morbidity. While computed tomography (CT) is the gold standard to measure visceral adiposity, this is often not possible for large studies - thus valid, but less expensive and intrusive proxy measures of visceral fat are required such as dual-energy X-ray absorptiometry (DXA). Study aims were to a) identify a valid DXA-based measure of visceral adipose tissue (VAT), b) estimate VAT heritability and c) assess visceral fat association with morbidity in relation to body fat distribution. Methods A validation sample of 54 females measured for detailed body fat composition - assessed using CT, DXA and anthropometry – was used to evaluate previously published predictive models of CT-measured visceral fat. Based upon a validated model, we realised an out-of-sample estimate of abdominal VAT area for a study sample of 3457 female volunteer twins and estimated VAT area heritability using a classical twin study design. Regression and residuals analyses were used to assess the relationship between adiposity and morbidity. Results Published models applied to the validation sample explained >80% of the variance in CT-measured visceral fat. While CT visceral fat was best estimated using a linear regression for waist circumference, CT body cavity area and total abdominal fat (R2?=?0.91), anthropometric measures alone predicted VAT almost equally well (CT body cavity area and waist circumference, R2?=?0.86). Narrow sense VAT area heritability for the study sample was estimated to be 58% (95% CI: 51-66%) with a shared familial component of 24% (17-30%). VAT area is strongly associated with type 2 diabetes (T2D), hypertension (HT), subclinical atherosclerosis and liver function tests. In particular, VAT area is associated with T2D, HT and liver function (alanine transaminase) independent of DXA total abdominal fat and body mass index (BMI). Conclusions DXA and anthropometric measures can be utilised to derive estimates of visceral fat as a reliable alternative to CT. Visceral fat is heritable and appears to mediate the association between body adiposity and morbidity. This observation is consistent with hypotheses that suggest excess visceral adiposity is causally related to cardiovascular and metabolic disease.

The relationship of anthropometric measures to radiological features of the breast in premenopausal women.  

PubMed Central

We studied 273 premenopausal women recruited from mammography units who had different degrees of density of the breast parenchyma on mammography, in whom we measured height, weight and skinfold thicknesses. Mammograms were digitized to high spatial resolution by a scanning densitometer and images analysed to measure the area of dense tissue and the total area of the breast. Per cent density and the area of non-dense tissue were calculated from these measurements. We found that the mammographic measures had different associations with body size. Weight and the Quetelet index of obesity were strongly and positively associated with the area of non-dense tissue and with the total area of the breast, but less strongly and negatively correlated with the area of dense tissue. We also found a strong inverse relationship between the areas of radiologically dense and non-dense breast tissue. Statistical models containing anthropometric variables explained up to 8% of the variance in dense area, but explained up to 49% of the variance in non-dense area and 43% of variance in total area. These results suggest that aetiological studies in breast cancer that use mammographic density should consider dense and non-dense tissues separately. In addition to per cent density, methods should be examined that combine information from these two tissues. Images Figure 1

Prenatal DDT Exposure in Relation to Anthropometric and Pubertal Measures in Adolescent Males  

PubMed Central

DDT (dichlorodiphenyltrichloroethane), a pesticide once used widely in agriculture and now limited to public health use, remains a controversial chemical because of a combination of benefits and risks. DDT or its breakdown products are ubiquitous in the environment and in humans. Compounds in the DDT family have endocrine actions and have been associated with reproductive toxicity. A previous study reported associations between prenatal exposure to p,p?-DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene] and increased height and weight in adolescent boys. We examined a group with higher exposures to see whether similar associations would occur. Our study group was 304 males born in Philadelphia in the early 1960s who had participated in a previous study. Anthropometric and pubertal measures from one to six visits during their adolescent years were available, as were stored maternal serum samples from pregnancy. We measured p,p?-DDE, p,p?-DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)-ethane], and o,p?-DDT [1,1,1-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl)-ethane] in the maternal serum. Outcomes examined in the boys were height, ratio of sitting height to height, body mass index, triceps skinfold thickness, ratio of subscapular to the sum of triceps and subscapular skinfold thicknesses, skeletal age, serum testosterone, and serum dehydroepiandrosterone sulfate. No associations between prenatal exposure to any of the DDT compounds and any outcome measure were seen.

Cranio facial anthropometric measurements among Rai and Limbu community of Sunsari District, Nepal.  

PubMed

Anthropometry is applied to obtain measurements of living subjects for identifying age, stature, and various dimensions related to particular race or an individual. Population based cross sectional study was carried out in Dharan and its neighbouring areas with the help of departments of Anatomy and Community Medicine, B.P. Koirala Institute of Health Sciences, Dharan. This study included 444 healthy people aged 25-50 years belonging to pure race of Rai and Limbu communities. Head length, nasal ergonomics and total stature were measured for each selected individual. Student't' test was applied to identify significance of the variables. Except nasal breadth of Limbu, the results showed a significant variation (p < 0.001) in all parameters between male and female of both the communities. It was also revealed that Limnbu males and females were taller with larger head length, longer nasal length and nasal height. Similarly nasal breadths of Limbu females were broader where as in males, Rai had broader nose than that of the Limnbu. Therefore it was concluded that anthropometric measurements can play significant role in determining the sex and ethnicity of characteristic pure races of national importance. PMID:20334066

Anthropometric measurements to design best-fit femoral stem for the Indian population  

PubMed Central

Background: The standard commercially available marketed prostheses sometimes may not be the best fit to Indian patients because of the large anatomic variation. Orthopedic surgeons always stress the need for a proper implant–patient match in hip joint replacements, in particular, for a cementless femoral stem. The complications of mismatch are aseptic loosening, improper load distribution, and discomfort. The present study was undertaken to compare the differences in dimensions between femurs of elderly Indians and those of populations from other regions in order to solve the problem of a possible geometric mismatch between a selected implant and the hip joint as far as Indian patients are concerned. Materials and Methods: Measurements were made using computer aided design techniques on computed tomography (CT) scanned images of 98 femurs (56 left and 42 right). The software used to convert the CT images into solid models was MIMICS® (Materialize, Inc., Leuven, Belgium). The geometrical parameters, viz., the femoral head offset, femoral head center (HC), femoral head diameter, femoral head relative position, position of shaft isthmus, neck-shaft angle, bow angle, femoral neck length, canal flare index, femoral length, and canal width at various locations, were chosen to design best-fit standard femoral stems for cementless insertion. These data were compared with the published data of other countries. Results: A difference of 16.8% was found in the femoral head offset between Indian and Swiss populations, which can affect soft tissue tension and range of motion. At a distance of 20 mm above the lesser trochanter (LT), the anteroposterior (AP) canal width was found to differ by 45.4%, when compared with a French population which can affect the mechanical stability of femoral stem. Femoral dimensions of Indian male and female subjects have also been compared and differences evaluated. At the LT, the aspect ratio (ratio of mediolateral canal width and AP canal width) in case of males (1.198) is approximately13% higher than that of females (1.059). Conclusions: This study indicates a need for redesign of femoral stems. The obtained anthropometric femoral dimensions can be used to design and develop indigenous hip joint prosthesis in India. The results of this study can also be used in forensic anthropometric studies.

Secular changes of anthropometric measures for the past 30 years in South-West Germany.  

PubMed

We investigated long-term changes in weight and skinfold thicknesses in German schoolchildren. In 2006, anthropometric measures were collected after a standardized protocol among 1079 children within the Ulm Research on Metabolism, Exercise and Lifestyle in children (URMEL-ICE) study. Data were compared with historical data (1975-1976). In URMEL-ICE, prevalence of overweight (IOTF criteria) was 16.5% (boys) and 17.3% (girls) and of obesity 3.5 and 3.6%, respectively. Compared with historical data the number of children above the 90th percentile(1975/76) increased statistically significantly for weight (approximately 150% both sexes), for subscapular (boys 288%, girls 206%) and triceps skinfold thickness (boys 460%, girls 413%). Statistically significant increases above the 50th percentile(1975/76) were found: weight 36 and 26%, subscapular 43 and 60% and triceps skinfold thickness 63 and 69% for boys and girls, respectively. Body fat among 6- to 9-year-old children increased dramatically within 30 years. Moreover, our data suggest substantial changes in body composition among normal-weight children towards an increased body fat mass. PMID:19690577

Maternal anthropometric measurements and other factors: relation with birth weight of neonates  

PubMed Central

The objective of this study was to examine the influence of anthropometric measurements of pregnant women, gestational weight gain, fundal height, and maternal factors, namely age, education, family income, parity along with maternal hemoglobin, on birth weight of neonates. A cross sectional study was performed in Khoy City in north west of Iran. Four hundred and fifty healthy pregnant women in the age between 16-40 years were selected for this study from seven health urban centers and one referral hospital. Findings showed that the mean age, height, fundal height, maternal weight, and gestational weight gain during pregnancy were 26.1 years, 159.1 cm, 32.9 cm, 72.0 kg, 11.8 kg respectively. The mean birth weight of neonates was 3.2 kg and 11% of neonates showed low birth weight. Age, family income, maternal height, weight, gestational weight gain and fundal height were significantly associated with birth weight of neonates. Using binary logistic regression analysis, fundal height, maternal hemoglobin, family income and gestational weight gain of pregnant women could be considered as predictive factors of birth weight of neonates.

An autopsy study of coronary atherosclerosis and its relation to anthropometric measurements/indices of overweight and obesity in men.  

PubMed

Atherosclerosis accounts for a large proportion of cardiovascular system associated morbidity and mortality. The present autopsy based study is aimed to study the correlation between coronary atherosclerosis and anthropometric measurements/indices of overweight and obesity such as; Waist Circumference (WC), Hip Circumference (HC), Body Mass Index (BMI), and Waist Hip Ratio (WHR) in men from southern India. The present research also analyses the correlation between anthropometric measurements/indices of overweight and obesity in men with number of coronaries affected with atherosclerosis in individuals. The study included 50 autopsies conducted in the Government District Wenlock Hospital, Mangalore during March and September 2008. The heart was dissected following standard autopsy protocol and a 5 cm section of the right coronary artery (RCA) in the atrio-ventricular groove from its origin, a 5 cm segment of the left anterior descending artery (LADA) distal to the origin of the circumflex artery, but including the region of origin of the circumflex branch and left coronary artery (LCA) from its origin till the circumflex branch were excised, dissected out, fixed in 10% formalin, marked for identification and sent for histopathological analysis. The study shows a positive correlation of WC and WHR with atherosclerotic changes in the RCA. The number of arteries affected with atherosclerosis is found to be well correlated with WC, BMI and WHR. The study confirms an association between anthropometric measurements/indices of obesity, grade of atherosclerosis in the RCA and the number of arteries affected with atherosclerosis. Anthropometric measurements/indices of obesity can be an effective means to identify high risk cases of atherosclerosis at an early stage that can be effective in reducing the associated cardiac morbidity and mortality.

Vegetable but not fruit intake during pregnancy is associated with newborn anthropometric measures.  

PubMed

We examined the relationship between consumption of fruit and vegetables during pregnancy and anthropometric measures at birth in a general population mother-infant cohort in Valencia, Spain. A total of 787 infants born between May 2004 and February 2006 were included. Fruit and vegetable consumption during pregnancy was assessed by a FFQ administered using an in-person interview. We used multiple linear regression to assess associations between fruit and vegetable intake (in quintiles) and birth weight and length adjusted for sex and gestational age, and logistic regression to assess being small for gestational age (SGA) in weight and SGA in length, defined as adjusted birth weight or length below the 10th percentile. A linear relationship was found between vegetable consumption and having a SGA (weight) and SGA (length) baby. Women in the lowest quintile of vegetable intake during the first trimester had a higher odds of having a SGA (weight) baby than women in the highest quintile [odds ratio (OR), 3.7; 95% CI: 1.5-8.9; P-trend < 0.001] and had a higher odds of having an SGA (length) baby in the third trimester (OR, 5.5; 95% CI: 1.7-17.7; P-trend = 0.04) in multivariate analysis. We found a nonmonotonic relationship between adjusted birth weight and length and vegetable consumption during the first trimester; newborns in the 2 lowest quintiles of intake had a significantly lower weight and length than those in the 4th quintile. There was no association between fruit consumption and birth outcomes. Our findings indicate that vegetable consumption throughout pregnancy may have a beneficial effect on fetal growth.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants that are known to induce oxidative stress. There have been several reports about the link between PAH exposure and complications in pregnancy. This cross-sectional study was conducted to: (1) measure the levels of benzo(a)anthracene (BaA), chrysene (Ch), benzo(b)fluoranthene (BbF), benzo(a)pyrene (BaP), and dibenzo(a,h)anthracene (DBahA) in placentas and maternal and -umbilical cord blood obtained at delivery from 1578 women between June 2005 and 2006 in the area of Al-Kharj, Saudi Arabia; (2) assess their influence on various anthropometric measures of birth outcome taking into consideration the carcinogenic properties of these PAHs; and (3) determine the degree of PAH-related oxidative DNA damage and birth outcome. Among the five tested PAHs, only BaP was carcinogenic; therefore, the levels of the other four probable or possible carcinogenic PAHs (BaA, Ch, BaF, and DBahA) were summed as ?4-PAHs. Levels of 1-hydroxypyrene (1-HP) were determined in maternal urine samples as a biomarker of PAH internal dose. Urinary cotinine (COT) was measured as an index of smoking. The following markers of oxidative stress were selected: malondialdehyde (MDA) in cord (C-MDA) and maternal (M-MDA) serum and 8-hydroxy-2-deoxyguanosine (8-OHdG) in maternal urine. None of the tested PAHs was found in maternal or cord blood. However, all five PAH compounds were detected in placentas; Ch was the highest (6.582 ?g/kg dry wt.), and BaA was the lowest (0.236 ?g/kg dry wt.). The mean concentration of urinary 1-HP found in this study was 0.216 ± 0.856 ?g/g Cr. After adjusting for gestational age and other confounding variables, regression models revealed an inverse relationship between placental weight, cord length and placental BaP. A similar trend was observed between cord length and ?4-PAHs in placental tissues. Urinary 1-HP, though, cannot be used as an unequivocal biomarker of PAH exposure, but it can be an appropriate indicator of exposure to environmental tobacco smoke (ETS). The data demonstrate that ETS exposure (as measured by urinary COT) may adversely affect birth outcome as shown by reduced head circumference, birth weight, and birth length, as well as increased cephalization index. The positive relationship between 8-OHdG levels and 1-HP in urine provides evidence of an oxidative stress mechanism. Although this study provides no direct evidence of an association between PAH exposure and DNA damage, increased oxidative stress in the form of lipid peroxidation significantly affected various birth measures. Therefore, there is a need for studies regarding PAH exposure and its associated biological effects to determine the extent of potential fetal damage as well as possible long-term effects, such as cancer.

Hand function measures for burn patients: a literature review.  

PubMed

Hand function is one of the most important goals of burn rehabilitation and is a consensually important functional outcome. The purpose of this article is to review the available hand function measures commonly used for burn patients and to summarize their psychometric properties and clinical utilities to serve as guidelines for clinical practice and research. An online-database search of PubMed, MEDLINE, CINAHL and PsychInfo was performed. One hundred and seventeen articles were found and 23 of them met the inclusion and exclusion criteria. The eight identified measurement instruments were then classified into three categories: traditional component measures, performance measures and patient-reported outcome measures. Each type of hand function measure has its unique characteristics and limitations. Traditional component measures only reflect hand impairments, and may not represent hand function status. Performance measures have not been validated in the burn population and do not correlate well with patient-reported outcomes. Patient-reported outcome measures have not been rigorously validated in the burn population. A discussion of how clinicians choose these measures reflecting the purposes of their measurements and goals of intervention is provided. Moreover, future studies are suggested to develop burn-specific hand function measures. PMID:22985975

The association of anthropometric measures and osteoarthritis knee in non-obese subjects: a cross sectional study  

PubMed Central

OBJECTIVE: Body mass index (BMI) and knee osteoarthritis have a strong association, but other anthropometric measures lack such associations. To date, no study has evaluated non?obese knee osteoarthritis to negate the systemic and metabolic effects of obesity. This study examines the validity of the contention that BMI and other anthropometric measures have a significant relationship with knee osteoarthritis. METHODS: In total, 180 subjects with a diagnosis of knee osteoarthritis were recruited and classified according to Kellgren?Lawrence (KL) grades. Body mass index, mid?upper arm circumference, waist?hip ratio and triceps?skinfold thickness were recorded by standard procedures. Osteoarthritis outcome scores (WOMAC) were evaluated. RESULTS: (1) In both genders, the BMI was significantly higher for KL grade 4 than for grade 2; triceps?skinfold thickness was positively correlated with the joint space width of the tibial medial compartment. (2) In males, triceps?skinfold thickness significantly increased as the KL grades moved from 2 to 4; the significantly higher BMI found in varus aligned knees was positively correlated with WOMAC scores. (3) In females, the waist?hip ratio was significantly higher for KL grade 4 than for grade 2; a significant correlation was found between BMI and WOMAC scores. The waist?hip ratio was significantly associated with varus aligned knees and it positively correlated with WOMAC scores and with the joint space width of the tibial medial compartment. The mid?upper arm circumference demonstrated no correlation with knee osteoarthritis. CONCLUSION: This study validates the contention that BMI and other anthropometric measures have a significant association with knee osteoarthritis. Contrary to common belief, the triceps?skinfold thickness (peripheral fat) in males and the waist?hip ratio (central fat) in females were more strongly associated with knee osteoarthritis than BMI.

The effects of tournament preparation on anthropometric and sport-specific performance measures in youth judo athletes.  

PubMed

The purpose of this study was to characterize the adaptations imposed by 4 weeks of precompetition judo training in youth athletes. It was hypothesized that anthropometric and sport-specific performance would improve during the preparation for a junior national championship event. Twenty youth athletes (mean ± SD; chronological age: 13.1 ± 3.2 years; training age: 5.3 ± 3.5 years; judo experience: 7.8 ± 2.5 hours per week) completed pretesting and posttesting procedures. Child (12 years old; n = 8) and adolescent (13 years old; n = 12) groups were evaluated to determine the anthropometric and sport-specific performance changes caused by 4 weeks of judo training conducted in preparation for the junior national championships. The child group showed an increase in flexibility (11.5%), and the adolescent group showed a decrease in skinfold thickness (-12.2%); increased jumping power (26.7%), force (7.7%), and velocity (19.0%); and improved judo-specific ability (-5.9%), as measured by the Special Judo Fitness Test (SJFT) index. Additionally, the SJFT index for all the study participants was shown to be inversely correlated to handgrip strength (r = -0.681), rope pull performance (r = -0.545), and jump height (r = -0.503). These results support the use of preparatory judo training in the improvement of anthropometric and sport-specific measures in adolescent athletes. Furthermore, the outcomes from this study provide direction for coaches and trainers in their efforts to impact physical performance and judo skills in children and adolescents through precompetition training.

Simple anthropometric measures correlate with metabolic risk indicators as strongly as magnetic resonance imaging-measured adipose tissue depots in both HIV-infected and control subjects2  

PubMed Central

Background 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. Objective We compared anthropometric and magnetic resonance imaging (MRI)–based adiposity measures as correlates of metabolic complications of adiposity in HIV-infected and control subjects. Design 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. Results 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 ? 0.07). Multivariate adjustment found no significant difference for optimally fitting models between the use of anthropometric and MRI measures, and the magnitudes of differences were small (adjusted R2 ? 0.06). For HOMA and HDL, WC appeared to be the best anthropometric correlate of metabolic complications, whereas, for triglycerides, the best was WHR. Conclusion 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.

Relationship of handgrip strength with anthropometric and body composition variables in prepubertal children.  

PubMed

The purpose of the present study was to examine the relationship of handgrip strength with basic anthropometric variables, hand anthropometric variables, total body and hand composition, total body and hand bone mineral density (BMD) and bone mineral content (BMC) in prepubertal children aged between 8 and 11 years (n=64, 27 boys, 37 girls). Height and body mass were measured and body mass index (BMI kg/m2) was calculated. Biceps and triceps skinfolds, arm relaxed, arm flexed, forearm and wrist girths, acromiale-radiale, radiale-stylion-radiale and midstylion-dactylion length and humerus breadth were measured. Specific hand anthropometric variables according to Visnapuu and Jürimäe [2007. Handgrip strength and hand dimensions in young handball and basketball players. J. Strength Cond. Res. 21, 923-929] were used. Five fingers' spans, fingers' lengths and perimeters of the hand were measured. Total body and right-hand fat percentage, fat mass and lean mass (LBM) were measured by dual-energy X-ray absorptiometry (DXA). Right-hand BMC and BMD were analysed from the bone variables. Maximal handgrip strength of the right hand was measured with the hand dynamometer. Stepwise multiple regression analysis indicated that the most important predictive value from the basic anthropometric variables was body height, explaining 76.1% (R2 x 100), 40.7% and 50.6% of the handgrip strength in boys, girls and total group, respectively. Measured skinfold thicknesses and breadths were not related to handgrip strength in any group. Forearm girths significantly predicted handgrip strength in boys (30.8%), girls (43.4%) and total group (43.4%). As a rule, handgrip strength was more dependent on the anthropometric and body composition variables in boys than girls. It was concluded that body height, forearm girth, midstylion-dactylion and acromiale-radiale length and hand LBM and BMC are the most limiting factors influencing handgrip strength in prepubertal children.

Prognostic significance of the Complex "Visceral Adiposity Index" vs. simple anthropometric measures: Tehran lipid and glucose study  

PubMed Central

Background Visceral adiposity index (VAI) has recently been suggested to be used as a surrogate of visceral adiposity. We examined if VAI could improve predictive performances for CVD of the Framingham's general CVD algorithm (a multivariate model incorporating established CVD risk factors). We compared the predictive abilities of the VAI with those of simple anthropometric measures i.e. BMI, waist-to-height ratio (WHtR) or waist-to-hip ratio (WHpR). Design and methods In a nine-year population-based follow-up, 6 407 (2 778 men) participants, free of CVD at baseline, aged ? 30 years were eligible for the current analysis. The risk of CVD was estimated by incorporating VAI, BMI, WHpR, and WHtR, one at a time, into multivariate accelerated failure time models. Results We documented 534 CVD events with the annual incidence rate (95%CIs) being 7.3 (6.4-8.3) among women and 13.0 (11.7-14.6) among men. Risk of future CVD increased with increasing levels of VAI among both men and women. VAI was associated with multivariate-adjusted increased risk of incident CVD among women. However, the magnitude of risk conferred by VAI was not significantly higher than those conferred by BMI, WHpR, or WHtR. Among men, after adjustment for established CVD risk factors, VAI was no longer associated with increased risk of CVD. VAI failed to add to the predictive ability of the Framingham general CVD algorithm. Conclusions Using VAI instead of simple anthropometric measures may lead to loss of much information needed for predicting incident CVD.

Anthropometric, body composition, and blood pressure measures among rural elderly adults of Asian Indian origin: the Santiniketan aging study.  

PubMed

The number of older adults is increasing in industrialized and in developing countries. The present community-based cross sectional work was undertaken to study the anthropometric, body composition, and blood pressure characteristics of rural-dwelling elderly adults of Asian Indian origin. A total of 300 individuals (Male = 157 and Female = 143) from the Bolpur-Sriniketan area of West Bengal, India, took part in the study. Participants were divided into four age-groups: Group I, 55-59 years (Male:Female = 55:61); Group II, 60-64 years (Male:Female = 41:33); Group III, 65-69 years (Male:Female = 27:21); Group IV, 70 years and older (Male:Female = 34:28). Anthropometric measures were taken using standard techniques. Body mass index, waist-hip ratio, and the sum of four skin folds were subsequently computed. Body composition measures, namely percentage of body fat, fat mass, fat free mass, arm muscle circumference, arm muscle area, and arm fat area, were calculated accordingly. Left-arm systolic (SBP) and diastolic blood pressures (DBP) were also measured, and mean arterial pressure was subsequently calculated. Overall observations in the study population indicate a predominance of body weights below the normal body mass index of 25 kg/m(2). More than half the subjects reported the lack of adequate sanitation facilities and education levels were generally low. Rates of smoking (65.6%) and habitual consumption of alcohol (38.9%) were high in male participants. Upon comparison across the four age groups, results revealed decreases in percent body fat, fat mass, and mid upper arm muscle circumference for Groups III and IV versus Group I for men and for Group IV versus I for women. The overall trend for both SBP and DBP was for small increases with age in men in contrast to slight decreases with age in women. Our findings of generally low body weights, detrimental age-related changes in body composition, and a number of other health-related concerns highlight the high level of nutritional risk in rural dwelling older adults of Asian Indian Origin. Clinicians conducting assessments in this population need to take these measures into account in order to fully account for potential health risks. PMID:21846245

Measurement of biodynamic response of human hand arm system  

NASA Astrophysics Data System (ADS)

Biodynamics of the human hand arm system is one of the most important foundations for understanding hand-transmitted vibration exposure and its health effects. Considerable differences among the reported data of the biodynamic response (BR) of the hand arm system have been observed. A significant portion of the differences are believed to have resulted from instrumentation problems and/or computational algorithm errors. To help establish a reliable and accurate methodology for BR measurement, this study addresses the fundamental instrumentation issues. Specifically, the general theory of the driving-point BR is reviewed and summarized. An accurate mass cancellation method for BR measurement is identified and further developed. A set of methods is proposed to systematically examine and calibrate the BR measurement system. Based on the experimental results and theoretical analyses, several instrumentation and algorithm problems are identified. This study demonstrated that the instrumentation problems can be resolved or avoided by appropriately selecting the force and motion sensors, improving the structure design of the instrumented handle and fixture, using the frequency-domain method for the handle mass cancellation, and conducting the static and dynamic calibrations of the measurement system using the proposed methods. The information and knowledge presented in this paper can help to generate reliable experimental data in further BR studies.

A prospective study of anthropometric and clinical measurements associated with insulin resistance syndrome and colorectal cancer in male smokers.  

PubMed

Type 2 diabetes mellitus shares risk factors for and has shown a positive association with colorectal cancer. Anthropometric measures (height, weight, and body mass index (weight (kg)/height (m)(2)) and metabolic abnormalities associated with insulin resistance syndrome (IRS) (abnormalities in measured blood pressure, high density lipoprotein (HDL) cholesterol, and total cholesterol) were prospectively evaluated for associations with incident colon (n = 227), rectal (n = 183), and colorectal (n = 410) cancers diagnosed between 1985 and 2002 in 28,983 Finnish male smokers from the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study. Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals. In comparison with the lowest quintile, the highest quintile of body mass index was significantly associated with colorectal cancer (hazard ratio (HR) = 1.70, 95% confidence interval (CI): 1.01, 2.85; p-trend = 0.01), particularly colon cancer. Subjects with a cluster of three IRS-related conditions (hypertension, body mass index >/=25 kg/m(2), and HDL cholesterol level <40 mg/dl (<1.55 mmol/liter)), compared with those with fewer conditions, had a significantly increased risk of colorectal cancer (HR = 1.40, 95% CI: 1.12, 1.74), particularly colon cancer (HR = 1.58, 95% CI: 1.18, 2.10), but not rectal cancer. These results support the hypothesis that the significant association observed between IRS-defining metabolic abnormalities and colorectal cancer is determined primarily by adiposity. PMID:16877536

Validity of child anthropometric measurements in the Special Supplemental Nutrition Program for Women, Infants and Children  

PubMed Central

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) serves 50% of infants and 25% of preschool-aged children in the U.S. and collects height and weight measurements from eligible children every six months, making WIC data a valuable resource for studying childhood growth and obesity. We assessed the accuracy of measurements collected by WIC staff by comparing them to “gold standard” measurements collected by trained research staff. At seven WIC clinics in southern California, 287 children ages 2–5 years measured by WIC staff using WIC standard protocol were re-measured by research staff using a research protocol (duplicate measurements with shoes and outerwear removed taken by trained personnel). Intraclass correlation coefficients measuring agreement between WIC and research protocol measurements for height, weight and body mass index (BMI) were 0.96, 0.99 and 0.93, respectively. Although WIC measurements overestimated height by 0.6 cm and weight by 0.05 kg on average, BMI was underestimated by only 0.15 kg/m2 on average. WIC BMI percentiles classified children as overweight/obese versus underweight/normal with 86% sensitivity and 92% specificity. We conclude that height, weight and BMI measurements of children aged 2–5 years collected by trained WIC staff are sufficiently accurate for monitoring and research purposes.

Smart mug to measure hand's geometrical mechanical impedance.  

PubMed

A novel device, which looks like a mug, has been proposed for measuring the impedance of human hand. The device is designed to have convenient size and light weight similar to an ordinary coffee mug. It contains a 2-axis inertia sensor to monitor vibration and a small motor to carry an eccentric mass (m=100 gr, r=2 cm, rpm=600). The centrifugal force due to the rotating mass applies a dynamic force to the hand that holds the mug. Correlation of the acceleration signals with the perturbing force gives the geometrical mechanical impedance. Experimental results on a healthy subject shows that impedance is posture dependant while it changes with the direction of the applied perturbing force. For nine postures the geometrical impedance is obtained all of which have elliptical shapes. The method can be used for assessment of spasticity and monitoring stability in patients with stroke or similar problems. PMID:22255230

Longitudinal anthropometric measurements in patients with growth hormone deficiency. Effect of human growth hormone treatment.  

PubMed

The effect of human growth hormone (6IU/m2 twice weekly i.m.) on standing, sitting, and subischial leg height, on arm length, head circumference, fronto-occipital and biparietal head diameter, bi-iliac (pelvis) and bihumeral (shoulder) width, body weight, triceps and subscapular skinfold thickness, and upper arm and calf circumferences was studied longitudinally over a period of 2 years in 37 prepubertal growth hormone deficient patients (29 boys, 8 girls). Thirteen of them had isolated growth hormone deficiency, 18 combined defects with other anterior pituitary hormone deficiencies, and 6 had been operated for a craniopharyngioma. The most retarded height and length measurements were influenced most markedly by treatment in the fashion of a characteristic catch-up growth, while head circumference, which was less retarded initially, increased more slowly. With exception of craniopharyngioma patients, who became slightly eunuchoid, both proportions (sitting height versus subischial leg height) were not changed by treatment. The disproportions of shoulder and hip width (relatively wide pelvis, narrow shoulders before treatment) tended to be normalized. The results in patients with operated craniopharyngioma were not as good as in those with idiopathic growth hormone deficiency. PMID:7075625

Body mass estimation in modern population using anthropometric measurements from computed tomography.  

PubMed

Forensic anthropologists are able to estimate the stature of a skeleton, its sex and biological age at death, with a relatively high degree of accuracy. Body mass estimation from the stature and bi-iliac (maximum pelvic) breadth and femoral head breadth can be useful in forensic investigations involving unidentified skeletal remains. Predicting the body mass of skeletal remains always involves significant inaccuracy, however when body mass extremes are disregarded average figures provide the best estimation. The aim of the study was to investigate whether the methods usually used in body mass estimation are accurate in different BMI ranges. The usefulness of these methods in forensic anthropology was discussed. The study was performed using CT images of widely differing body types of modern central European populations. Maximum pelvic breadth and anteroposterior femoral head breadth were measured directly from the appropriate CT scan slices for each individual. Body mass index was established for each individual. Four different methods of body mass estimation were applied. The statistical analysis showed that body mass prediction methods based on the bi-iliac breadth with known stature and the femoral head breadth show strong correspondence. The results of body mass estimation using different methods were in high correlation with normal BMI. The accuracy of body mass prediction of underweight and obesity cases (BMI extremes) showed significant inaccuracy. Body mass estimation methods can provide important information for forensic anthropological investigation and personal identification. However, one should be aware of the discrepancies and should apply the equations carefully as they can carry significant errors. PMID:23751731

Optimal brassiere wire based on the 3D anthropometric measurements of under breast curve.  

PubMed

It has been difficult to quantify the fit of brassiere wire to the natural nude under breast line due to the difficulty of obtaining women's nude under breast line in 3D image. The objectives of this study are firstly to design the ergonomic brassiere wire that should fit to the curve of under breast and thorax and secondly to apply the 3D measurement of human body structure to the product design and evaluation using phase shifting moiré topography. Eight brassiere wires were evaluated and key factors of comfortable wires were selected depending on the types of women's under breast those are considered as backbones of the brassiere structure. Twenty-one middle-aged women participated in the subjective wear test, and 17 volunteers of them continued to participate in the 3D image recording. 3D morphological data of the breast before and after wearing experimental brassiere was examined by phase shifting moiré topography. As results, it was found that the fitting of the global average radius of curvature of wire to that of the body line of the under breast curve was an important variable for the design of wires. Conventional shape of brassiere wire was suitable to the majority of the subjects. However, for those who have skewed under breast lines, the wire of larger global average radius of curvature along the inner part of the under breast line was rated higher in terms of wear comfort and appearance. The recommended magnitude of the torsional rigidity of the brassiere wire was about 0.015 N/mm2mm. The observation on women's under breast curve and their comfortable breast wire as discussed in this paper would provide with comfortable and stable fit for women in special needs such as soldiers, athletes and actress.

Ponderal somatograms assess changes in anthropometric measurements over an academic year in Division III collegiate football players.  

PubMed

Ponderal somatograms evaluate body size and shape by converting muscular (shoulders, chest, biceps, forearm, thigh, calf) and nonmuscular (abdomen, hips, knee, ankle, wrist) girths into ponderal equivalent (PE) values. Anthropometric measurements, including stature, body mass, girths, and percent body fat by densitometry were collected in 54 Division III football players in preseason camp (fall) and at the beginning (winter) and end (spring) of the team strength and conditioning program. PE values were calculated for each girth as PE, kg = (girth, cm / k)(2) x stature, dm, where k = k constant from Behnke's reference man. PE values were compared to body mass to indicate overdevelopment (PE > body mass) and underdevelopment (PE < body mass) at specific girth sites. From fall to winter, body mass (+1.6 kg), percent fat (+1.3%), fat mass (+1.6 kg), nonmuscular abdominal and hip girths (+2.1 cm, +1.5 cm), and PE values (+5.3 kg, +2.6 kg) increased significantly (p < 0.05). From winter to spring, percent fat (-1.5%), fat mass (-1.4 kg), nonmuscular abdominal girth (-1.0 cm), and PE value (-2.5 kg) decreased significantly (p < 0.05). Fat-free mass (+1.5 kg), muscular biceps girth (+0.4 cm), and PE value (+2.6 kg) increased significantly (p < 0.05) from winter to spring. Ponderal somatogram muscular components were generally overdeveloped, with the greatest overdevelopment at the biceps in fall (+14.7 kg), winter (+14.9 kg), and spring (+17.4 kg). Nonmuscular components generally were underdeveloped, except abdomen and hips that were overdeveloped. The abdomen remained the greatest nonmuscular overdevelopment in fall (+6.8 kg), winter (+10.5 kg), and spring (+7.9 kg). Ponderal somatograms provide a relatively simple, practical method to track specific changes in body size and shape over time. PMID:17685687

Sound power measurement techniques for powered hand tools  

NASA Astrophysics Data System (ADS)

As part of a project to reduce noise induced hearing loss in the construction industry, NIOSH developed a database of sound power level measurements of electric powered hand tools typically used in the construction industry. The tool testing jigs and setups specified and illustrated in ANSI S12.15 were modified to accommodate the higher precision ten-microphone arrangement used in ISO 3744. ANSI S12.15 is sometimes vague regarding the tool testing jig design, so test jigs were designed to supplement existing specifications in the standard. In the course of the project, test jigs were designed, techniques were devised to improve repeatability of measurements, to reduce waste materials, to reduce measurement setup time, and to reduce data acquisition time. Several types of tools were tested including circular saws, grinders, screw drivers, drills, jig saws, reciprocating saws, miter saws, hammer drills, belt sanders, and impact wrenches. The test jig designs and measurement techniques may help others to save time, reduce waste material, and improve measurement repeatability. Additionally, a microphone was placed in the nominal hearing zone of the tool operator to acquire a time series to assess other sound metrics.

Predicting maximal grip strength using hand circumference.  

PubMed

The objective of this study was to analyze the correlations between anthropometric data and maximal grip strength (MGS) in order to establish a simple model to predict "normal" MGS. Randomized bilateral measurement of MGS was performed on a homogeneous population of 100 subjects. MGS was measured according to a standardized protocol with three dynamometers (Jamar, Myogrip and Martin Vigorimeter) for both dominant and non-dominant sides. Several anthropometric data were also measured: height; weight; hand, wrist and forearm circumference; hand and palm length. Among these data, hand circumference had the strongest correlation with MGS for all three dynamometers and for both hands (0.789 and 0.782 for Jamar; 0.829 and 0.824 for Myogrip; 0.663 and 0.730 for Vigorimeter). In addition, the only anthropometric variable systematically selected by a stepwise multiple linear regression analysis was also hand circumference. Based on this parameter alone, a predictive regression model presented good results (r(2) = 0.624 for Jamar; r(2) = 0.683 for Myogrip and r(2) = 0.473 for Vigorimeter; all adjusted r(2)). Moreover a single equation was predictive of MGS for both men and women and for both non-dominant and dominant hands. "Normal" MGS can be predicted using hand circumference alone. PMID:20708427

A new anthropometric phantom for calibrating in vivo measurements of stable lead in the human leg using X-ray fluorescence  

SciTech Connect

A new anthropometric phantom has been developed for calibrating in vivo measurements of stable lead deposited in bone using x-ray fluorescence. The phantom reproduces the shape of the mid shaft of the adult human leg and is fabricated using polyurethanes and calcium carbonate to produce materials that exhibit the same density, energy transmission, and calcium content as cortical bone, bone marrow, and muscle. The phantom includes a removable tibia fabricated using simulants for cortical bone and bone marrow to which a precise amount of stable lead has been added to cortical bone. The formulations used in fabricating the new anthropometric phantom are much more uniform in density and composition than the conventional phantom made from Plexiglas cylinders filled with plaster-of-Paris. The energy spectrum from an x-ray fluorescence measurement of the phantom using a {sup 109}Cd source is indistinguishable from an in vivo x-ray fluorescence measurement of the human leg, demonstrating that the materials used in the phantom exhibit the same radiological properties as human tissue. Likewise, results from x-ray fluorescence measurements of the phantom exhibit the same positional dependency as the human leg and vary by approximately 36% when, for example, the phantom containing 54 ppm of stable lead in the tibia was rotated by only 15 degrees. The detection limit for a 30 min {sup 109}Cd K shell x-ray fluorescence in vivo measurement is approximately 20 ppm determined from a background measurement using the new phantom containing no added lead in the muscle, bone, or bone marrow. The new anthropometric phantom significantly improves in vivo x-ray fluorescence calibration measurements by (1) faithfully reproducing the anatomy of the human leg, (2) having components that exhibit radiological properties similar to that of human tissue, and (3) providing a realistic calibration standard that can be used for in vivo x-ray fluorescence intercomparison measurements.

Genetic architecture of hand quantitative ultrasound measures: a population-based study in a Sardinian genetic isolate.  

PubMed

It is now recognized that quantitative ultrasound (QUS) measures may predict osteoporotic fracture risk independently of bone mineral density. Although many studies have examined genetic and environmental components of bone mineral density and calcaneal QUS measures, few of them were addressed to phalangeal QUS phenotypes, and none to graphic trace parameters. This study aims to evaluate the relative contribution of genetics in the expression of phalangeal QUS traits in the adult healthy population of a Sardinian genetic isolate. Our sample includes 6056 men and women aged 30-103 years, from 43 extended pedigrees recruited in 10 villages of Ogliastra region in occasion of a large epidemiologic survey. Amplitude-dependent speed of sound (AD-SoS), fast wave amplitude (FWA), signal dynamic (SDy), bone transmission time (BTT) and ultrasound bone profile index (UBPI) were obtained from the non-dominant hand using the IGEA DBM Sonic Bone Profiler. These phenotypes were first regressed on age, anthropometric and bioimpedance measures, serum calcium, phosphorus and alkaline phosphatase, alcohol and caffeine consumption, smoking status, exercise and also months since menopause and estrogens use in women. Adjusted QUS parameters were then analyzed by univariate and bivariate variance component models to obtain heritability estimates and genetic and environmental correlations. QUS parameters were correlated to age, anthropometric and bioimpedance measures, serum phosphorus, alkaline phosphatase and to reproductive history and menopause in women. All phenotypes demonstrated substantial heritabilities ranging from 0.29+/-0.03 for SDy to 0.55+/-0.03 for FWA. Proportion of variance due to all covariates ranged from 36% for SDy to 59% for BTT. Many significant genetic and environmental correlations were found between the different QUS measures. In this study, genetic factors appear to play a relevant role in determining hand QUS measures even when taking into account various important environmental factors. Furthermore, the modest genetic correlations may imply the existence of partially unique sets of genes affecting different QUS traits, thus suggesting that QUS parameters measure different properties of bone tissue.

A comparison between handgrip strength, upper limb fat free mass by segmental bioelectrical impedance analysis (SBIA) and anthropometric measurements in young males  

NASA Astrophysics Data System (ADS)

The mechanical function and size of a muscle may be closely linked. Handgrip strength (HGS) has been used as a predictor of functional performing. Anthropometric measurements have been made to estimate arm muscle area (AMA) and physical muscle mass volume of upper limb (ULMMV). Electrical volume estimation is possible by segmental BIA measurements of fat free mass (SBIA-FFM), mainly muscle-mass. Relationship among these variables is not well established. We aimed to determine if physical and electrical muscle mass estimations relate to each other and to what extent HGS is to be related to its size measured by both methods in normal or overweight young males. Regression analysis was used to determine association between these variables. Subjects showed a decreased HGS (65.5%), FFM, (85.5%) and AMA (74.5%). It was found an acceptable association between SBIA-FFM and AMA (r2 = 0.60) and poorer between physical and electrical volume (r2 = 0.55). However, a paired Student t-test and Bland and Altman plot showed that physical and electrical models were not interchangeable (pt<0.0001). HGS showed a very weak association with anthropometric (r2 = 0.07) and electrical (r2 = 0.192) ULMMV showing that muscle mass quantity does not mean muscle strength. Other factors influencing HGS like physical training or nutrition require more research.

The relevant research is questioning the essence of the existence of an adequate internal circulation to human dimensions. The research was based on the method of anthropometric assessment of internal circulation de Barros (2009), which was applied in three different sizes of apartments in the city of Caruaru-PE. These apartments were evaluated through the floor plans and furniture layouts, suggested by the builders, with the use of anthropometric models in simulation of movement. The study found that traffic problems are not just a consequence of small rooms, but projects that do not bother to match the anthropometric measurements to the space environment. PMID:22317306

Anthropometric measures and the risk of endometrial cancer, overall and by tumor microsatellite status and histological subtype.  

PubMed

Obesity is an established risk factor for endometrial cancer, but this association is not well understood for subtypes of endometrial cancer. We evaluated the association of recent and adult-life obesity with subtypes of endometrial cancer based on microsatellite status (microsatellite-stable (MSS) vs. microsatellite-instable (MSI)) and histology (type I vs. type II). Analyses were based on a population-based case-control study (524 cases and 1,032 controls) conducted in Alberta, Canada (2002-2006) and included the following groupings of subtypes: MSS = 337 and MSI = 130; type I = 458 and type II = 66. Logistic and polytomous logistic regression were used to estimate odds ratios and 95% confidence intervals for overall endometrial cancer and subtypes of endometrial cancer, respectively. The risks of all subtypes of endometrial cancer, except type II, increased with an increase in all of the anthropometric characteristics examined. The risks for MSI tumors were suggestively stronger than those for MSS tumors; the risk with high (?30) body mass index (weight (kg)/height (m)(2)) was significantly stronger for MSI tumors (odds ratio = 4.96, 95% confidence interval: 2.76, 8.91) than for MSS tumors (odds ratio = 2.33, 95% confidence interval: 1.66, 3.28) (P-heterogeneity = 0.02). Obesity is associated with most subtypes of endometrial cancer, and further studies are warranted to elucidate the biological mechanisms underlying the stronger risk for the MSI subtype with a high body mass index.

Development of an observational measure of healthcare worker hand-hygiene behaviour: the hand-hygiene observation tool (HHOT).  

PubMed

Previous observational measures of healthcare worker (HCW) hand-hygiene behaviour (HHB) fail to provide adequate standard operating procedures (SOPs), accounts of inter-rater agreement testing or evidence of sensitivity to change. This study reports the development of an observational tool in a way that addresses these deficiencies. Observational categories were developed systematically, guided by a clinical guideline, previous measures and pilot hand-hygiene behaviour observations (HHOs). The measure, a simpler version of the Geneva tool, consists of HHOs (before and after low-risk, high-risk or unobserved contact), HHBs (soap, alcohol hand rub, no action, unknown), and type of HCW. Inter-observer agreement for each category was assessed by observation of 298 HHOs and HHBs by two independent observers on acute elderly and intensive care units. Raw agreement (%) and Kappa were 77% and 0.68 for HHB; 83% and 0.77 for HHO; and 90% and 0.77 for HCW. Inter-observer agreement for overall compliance of a group of HCWs was assessed by observation of 1191 HHOs and HHBs by two pairs of independent observers. Overall agreement was good (intraclass correlation coefficient = 0.79). Sensitivity to change was examined by autoregressive time-series modelling of longitudinal observations for 8 months on the intensive therapy unit during an Acinetobacter baumannii outbreak and subsequent strengthening of infection control measures. Sensitivity to change was demonstrated by a rise in compliance from 80 to 98% with an odds ratio of increased compliance of 7.00 (95% confidence interval: 4.02-12.2) P < 0.001. PMID:18478625

Proposal of a new measurement technique for hand-arm vibration analysis  

NASA Astrophysics Data System (ADS)

In this paper a new measurement technique to analyze hand-arm vibration is proposed. The methodology is based on a laser scanning vibrometer, a new instrument that measures, without contact, vibration on grid points on a surface. The technique can be applied in laboratory tests and also to perform in field tests on hand-guided vibrating tools, vehicles, machine. Tests with sinusoidal vibrations up to 250 Hz have been performed on different subjects with their hand on three test devices, designed accordingly to ISO standards, has been used to verify the measurement technique. Further work has been started in order to develop a measurement system for mapping the mechanical impedance measurements in some points of the hand of different subjects are illustrated. These techniques prove to be very powerful to analyze hand-arm dynamic characteristics.

Measurement of a number of indices of hand and movement angles in pianists with overuse disorders.  

PubMed

Abduction angles of the thumb and little finger, hand span, length of thumb, middle finger and little finger were measured using radiographs of the right hand with the thumb and the little finger abducted, in a comparative study of 220 pianists with overuse disorder and 62 unaffected pianists. Overuse disorders included tenosynovitis, lateral and medial epicondylitis, forearm flexor muscle pain, distal tendinitis of the wrist extensors and flexors and intrinsic muscle pain. Hand span or other hand size parameters showed significant differences, while abduction angles showed no difference. The patients' group had smaller hand size than the controls when analyzed for tenosynovitis, epicondylitis and muscle pain. From these results we hypothesize that pianists with small hands tend to hyper-abduct and hyper-extend the thumb to attain greater hand span. Their little finger is also stiffer and the hypothenar muscle and the wrist flexors need greater strength to resist the reaction force in each piano key. PMID:20427408

Prediction of fat-free mass and percentage of body fat in neonates using bioelectrical impedance analysis and anthropometric measures: validation against the PEA POD.  

PubMed

Accurate assessment of neonatal body composition is essential to studies investigating neonatal nutrition or developmental origins of obesity. Bioelectrical impedance analysis or bioimpedance analysis is inexpensive, non-invasive and portable, and is widely used in adults for the assessment of body composition. There are currently no prediction algorithms using bioimpedance analysis in neonates that have been directly validated against measurements of fat-free mass (FFM). The aim of the study was to evaluate the use of bioimpedance analysis for the estimation of FFM and percentage of body fat over the first 4 months of life in healthy infants born at term, and to compare these with estimations based on anthropometric measurements (weight and length) and with skinfolds. The present study was an observational study in seventy-seven infants. Body fat content of infants was assessed at birth, 6 weeks, 3 and 4·5 months of age by air displacement plethysmography, using the PEA POD body composition system. Bioimpedance analysis was performed at the same time and the data were used to develop and test prediction equations for FFM. The combination of weight+sex+length predicted FFM, with a bias of < 100 g and limits of agreement of 6-13 %. Before 3 months of age, bioimpedance analysis did not improve the prediction of FFM or body fat. At 3 and 4·5 months, the inclusion of impedance in prediction algorithms resulted in small improvements in prediction of FFM, reducing the bias to < 50 g and limits of agreement to < 9 %. Skinfold measurements performed poorly at all ages. PMID:21917194

Randomized Controlled Pilot Trial of Yoga in Overweight and Obese Breast Cancer Survivors: Effects on Quality of Life and Anthropometric Measures  

PubMed Central

PURPOSE To obtain estimates of time to recruit the study sample, retention, facility-based class attendance and home practice for a study of yoga in breast cancer survivors, and its efficacy on fatigue, quality of life (QOL), and weight change. METHODS Sixty-three post-treatment stage 0–III borderline overweight and obese (body mass index ? 24 kg/m2) breast cancer survivors were randomly assigned to a 6-month, facility- and home-based viniyoga intervention (n = 32) or a waitlist control group (n = 31). The yoga goal was 5 practices per week. Primary outcome measures were changes in self-reported QOL, fatigue, and weight from baseline to 6 months. Secondary outcomes included changes in waist and hip circumference. RESULTS It took 12 months to complete recruitment. Participants attended a mean of 19.6 classes and practiced at home a mean of 55.8 times during the 6-month period. At follow-up, 90% of participants completed questionnaires and 87% completed anthropometric measurements. QOL and fatigue improved to a greater extent among women in the yoga group relative to women in the control group, although no differences were statistically significant. Waist circumference decreased 3.1 cm (95% CI: ?5.7, ?0.4) more among women in the yoga compared with the control group, with no differences in weight change. CONCLUSIONS This study provides important information regarding recruitment, retention, and practice levels achieved during a 6-month, intensive yoga intervention in overweight and obese breast cancer survivors. Yoga may help decrease waist circumference and improve quality of life; future studies are needed to confirm these results.

Relationship of five anthropometric measurements at age 18 to radiation dose among atomic bomb survivors exposed in utero  

SciTech Connect

Five body measurements-standing height, body weight, sitting height, chest circumference and intercristal diameter-of 18-year-old atomic bomb survivors exposed in utero in Hiroshima and Nagasaki were analyzed in relation to DS86 uterine dose. Age in utero was divided into four periods: 0-7, 8-15, 16-25 and [>=]26 weeks. This categorization is based upon the study of radiation-induced brain damage. The linear regression analyses for these five variables showed significant decreases with increasing dose. The regression coefficients were -2.65 cm/Gy for standing height, -2.46 kg/Gy for body weight, -0.92 cm/Gy for sitting height, -1.37 cm/Gy for chest circumference and -0.32 cm/Gy for intercristal diameter. The multivariate test statistic for the overall dose effect on five body measurements was significant, but the interaction between dose and gestational period was not significant. Principal-component analysis was applied to the five variables. For the first-component scores, the dose effect was significant, but the interaction between dose and gestational period was not significant. For the second-component scores, the dose effect was significant specifically at 0.7 weeks. The radiation dose effect on the second principal component found at 0-7 weeks of gestation suggests that malformation occur in this period. 17 refs., 2 figs., 4 tabs.

Healthcare workers' and parents' perceptions of measures for improving adherence to hand-hygiene  

PubMed Central

Background This study was conducted to evaluate perceptions of healthcare workers (HCW) and parents regarding hand-hygiene and effectiveness of measures for increasing hand-hygiene adherence, in a children's hospital in Italy. Methods A cross-sectional study was performed from 5 to 13 July 2010, using two self-administered anonymous questionnaires (one for HCWs and one for parents/caregivers). The questionnaires included information regarding individual perceptions associated with hand hygiene. Results We collected 139 questionnaires from HCWs and 236 questionnaires from parents. Alcohol-based handrub was reported to be available at the point of care by 95.0% of the HCWs and in the child's room by 97.0% of the parents. For both HCWs and parents, availability of alcohol-based handrub was perceived as the most useful action for improving adherence to hand hygiene (scores ? 6 on a 7-point Likert-type scale: 84.8% [CI95%78.0-90.1] for HCWs and 87.9% [CI95% 83.3-91.7] for parents). Parents' reminding HCWs to perform hand hygiene was perceived as the least useful action (scores ? 6: 48.9% [CI95% 40.5-57.3] for HCWs and 55.7% [CI95% 49.2-62.1] for parents). Factors that affected HCWs' perceptions of the effectiveness of actions for improving adherence to hand hygiene included years of practice, type of ward and previous formal training on hand hygiene. For parents, factors affecting perceptions included previous information on hand hygiene and previous hospitalizations for their child. Conclusions Investigating HCWs' and parents' perceptions of measures for improving adherence can provide useful information for implementing actions for hand-hygiene promotion in children's hospitals. In this study, HCWs' and parents' perceptions were similar; alcohol-based hand-rub availability was perceived as the most useful tool, confirming its crucial role in multimodal interventions. Poor perception of inviting parents to remind HCWs to perform hand-hygiene has been previously observed, and deserves further investigation. Information and education activities were associated with more positive perceptions regarding various improvement measures. Though the relationship between perceptions and behaviours remains to be fully determined, HCWs should participate in formal training and families should be properly informed, not only to increase knowledge but also to improve perceptions on effectiveness of actions to be implemented.

Analysis of handle dynamics-induced errors in hand biodynamic measurements  

NASA Astrophysics Data System (ADS)

Reliable experimental data of the driving-point biodynamic response (DPBR) of the hand arm system are required to develop better biodynamic models for several important applications. The objectives of this study are to enhance the understanding of mechanisms of errors induced via the dynamics of instrumented handles and to identify a relatively more reliable method for DPBR measurement. A model of the handle hand arm system was developed and applied to examine various measurement methods. Both analytical and finite element methods were used to perform the examinations. This study found that the handle dynamic response could cause an uneven vibration distribution on its structures, especially at high frequencies (?500 Hz), and hand coupling on the handle could influence the distribution characteristics. Whereas the uneven distribution itself could directly result in measurement error, the hand coupling-induced vibration changes could cause errors in tare mass cancellation. The essential reason for both types of error is that the acceleration measured at one point on the handle may not be the same as that distributed at other locations. Because the cap measurement method that separately measures the DPBRs distributed at the fingers and palm can minimize both types of error, it is the best one among the methods examined in this study. The theory developed in this study can be used to help select, develop, and improve the measurement method for a specific application.

Anthropometric characteristics evolution in elite rhythmic gymnasts.  

PubMed

The aims of this research were to assess anthropometric characteristics of high-level senior and junior rhythmic gymnasts; and was to investigate the changes of anthropometric characteristics over a 4 years period, in different senior and junior groups of the same technical level. Twenty anthropometric variables of 63 participants were collected and body composition and sitting-height-to-stature-ratio measures were calculated. The two-way (gymnast category and time) ANOVA of the anthropometric characteristics showed significant main effect of time period for biacromial and bicristal diameters indicating that the majority of variables had similar values in 2002 and 2006. A significant main effect of category (junior or senior) was present in most the analyzed variables with higher values in senior gymnasts than juniors. The significant category by time interaction for height, weight, limbs' length, and fat-free mass, indicated that some differences between junior and senior gymnasts increased over the 4 yr time period. The training hours per week were significantly higher in seniors, but did not differ over the 4 yr period. The study shows that the criteria, followed for the recruitment of elite gymnasts, in the two different periods considered (2002 and 2006) were almost the same. Moreover, higher differences between seniors and juniors of FFM values in 2006 indicated the more intensive training of the second period for seniors. PMID:18491452

The influence of anthropometric characteristics to the handgrip and pinch strength in 6-10-year old children.  

PubMed

The aim of the study was to investigate the relationships between handgrip and pinch strength values with basic body (body height, body mass, BMI) and with specific hand anthropometric parameters (fingers spans, lengths and perimeters) in prepubertal children. Body height, body mass and five fingers spans, lengths and perimeters were measured in 461 6-10 year old Estonian children according to Visnapuu & Jürimäe (2007). BMI was calculated (kg/m2). The maximal handgrip strength of the right and left hand was measured with hand dynamometer. The right and left key and tip pinch were measured with a pinch gauge. Body height, as a rule, in combination with BMI, was the strongest predictor of handgrip strength, especially in older children (about 40-60 % of the total variance, R2 x 100). From the hand anthropometry, the most important span parameter was FS2 (see explanations in the methods), which explained about 10-50% (R2 x 100) of the total variance. In older groups, the FS1 and FS3 were added to the models. From the length parameters, the most important was IFL, which in younger groups together with MFL explained 10-30% of the total variance, and in older groups the addition of RFL increased the influence to 45% (R2 x 100). From the perimeters, the most important one was P2 which explained the variability of the handgrip strength in younger groups by 15-30% (R2 x 100) and in older groups together with P3 and P4 even 30-40%. In children, the basic anthropometric parameters (body height and BMI) contribute more to the prediction of handgrip strength than the specific anthropometric parameters. With increasing age the contribution of basic and specific hand anthropometry increases and the relation between anthropometry and handgrip strength is stronger in boys compared with girls. The relation of basic and hand anthropometry to the tip and key pinch strength is relatively low. PMID:17987909

In vivo measurement of carpal tunnel pressure in the functioning hand.  

PubMed

We recorded directly the pressure within the carpal tunnel during nine different functional positions of the hand and wrist in 102 hands of 92 subjects. Carpal tunnel syndrome was present in 81 hands, and 21 served as controls. A significant rise in pressure was recorded not only with wrist flexion but also with wrist extension, making a fist, holding objects, and isolated isometric flexion of a finger against resistance. Intratunnel pressure dropped after 1 minute of hand and wrist exercises and remained below the resting pressure for over 15 minutes of continuous measurement. We did not observe a rebound phenomenon. Clinical Application: Non-surgical treatment of carpal tunnel syndrome should also include a significant reduction in making a fist, holding objects, pushing, and isolated finger work such as key punching and typing. Activities that require sustained contracture of finger flexor muscles (eg, grasp and hold) also should be avoided. Brief intermittent wrist and hand exercise is recommended to reduce the intratunnel pressure. PMID:8522756

Changes in anthropometric measurements, body composition, blood pressure, lipid profile, and testosterone in patients participating in a low-energy dietary intervention  

PubMed Central

Objective The purpose of this study was to describe changes in anthropometric measurements, body composition, blood pressure, lipid profile, and testosterone following a low–energy-density dietary intervention plus regimented supplementation program. Methods The study design was a pre-post intervention design without a control group. Normal participants were recruited from the faculty, staff, students, and community members from a chiropractic college to participate in a 21-day weight loss program. All participants (n = 49; 36 women, 13 men; 31 ± 10.3 years of age) received freshly prepared mostly vegan meals (breakfast, lunch, and dinner) that included 1200 to 1400 daily calories (5020.8 to 5857.6 J) for the women and 1600 to 1800 (6694.4 to 7531.2 J) daily calories for the men. Nutritional supplements containing enzymes that were intended to facilitate digestion, reduce cholesterol levels, increase metabolic rate, and mediate inflammatory processes were consumed 30 minutes before each meal. The regimented supplementation program included once-daily supplementation with a green drink that contained alfalfa, wheatgrass, apple cider vinegar, and fulvic acid throughout the study period. A cleanse supplementation containing magnesium, chia, flaxseed, lemon, camu camu, cat's claw, bentonite clay, tumeric, pau d'arco, chanca piedra, stevia, zeolite clay, slippery elm, garlic, ginger, peppermint, aloe, citrus bioflavonoids, and fulvic acid was added before each meal during week 2. During week 3, the cleanse supplementation was replaced with probiotic and prebiotic supplementation. Results Multiple paired t tests detected clinically meaningful reductions in weight (? 8.7 ± 5.54 lb) (? 3.9 ± 2.5 kg), total cholesterol (? 30.0 ± 29.77 mg/dL), and low-density lipoprotein cholesterol (? 21.0 ± 25.20 mg/dL) (P < .05). There was a pre-post intervention increase in testosterone for men (111.0 ± 121.13 ng/dL, P < .05). Conclusions Weight loss and improvements in total cholesterol and low-density lipoprotein cholesterol levels occurred after a low–energy-density dietary intervention plus regimented supplementation program.

Negative pressure therapy with irrigation for digits and hands: pressure measurement and clinical application.  

PubMed

We recently developed continuous negative pressure therapy with irrigation (NPI) and successfully applied it to an infected digit with a narrow wound. With this technique, however, the dressing circumferentially wraps the digit or hand, and the pressure that the digit or hand receives and the influence on peripheral circulation are unclear. In this report, we evaluated the external pressure that a digit and hand received during NPI in vitro. Under circumferential NPI dressing, the skin perfusion pressure (SPP) of the peripheral portion was measured. Pressure was maintained at 1.3 mm Hg, and suction pressure ranged from -50 to -200 mm Hg. The pressure that a digit or hand receives during NPI is much lower than that at which tissue may be damaged (40-50 mm Hg). The SPP of the peripheral portion was much higher than 40 mm Hg, which is the pressure at which wound healing may be predicted. In clinical cases, NPI has been useful for wound bed preparation.

Sampling and analytical method development and hand wipe measurements of dermal exposures to polycyclic aromatic hydrocarbons.  

PubMed

This article describes the laboratory assessment of a hand and surface wipe sampling method for polycyclic aromatic hydrocarbons (PAHs). The analytical method employed extraction of the wipe samples into dimethyl sulfoxide (DMSO) and high-performance liquid chromatography (HPLC) flourometric detection of pyrene, a predominant PAH in used gasoline engine oils (UGEO). Recovery of pyrene was evaluated for two different sampling media by first contaminating the hands of a small number of volunteers with UGEO, followed by applying a small amount of corn oil to the palms, and by wiping the skin with a Whatman cellulostic filter paper or a polyester fabric wipe (i.e., Alpha wipes). In summary, using either Whatman or Alpha wipes, the mean recovery of pyrene from the UGEO that was applied to the hands and contained within three consecutive wipes was 69% and 54%, respectively. However, the relative recovery of the first to second wipe was on average 47% and 75% for the two media, respectively. These results indicate that the Alpha wipes were more efficient at recovering pyrene in the first wipe but less efficient overall when all three consecutive samples were included. Even though this sampling was performed in a controlled laboratory environment, the minimum and maximum amount of pyrene recovered in the individual composite samples using either method spanned a range of twofold. Overall, intra-and interpersonal variability, as measured by coefficient of variation, were 22% and 19%, respectively, and were not statistically different by type of media used. This method was used in a pilot field survey to sample the hands of 18 automotive repair technicians and 18 office workers. Detectable amounts of pyrene (>0.2 microg/sample) were found on the hands of 61% and 0% of these two groups, respectively, with the highest measured quantity equal to 1.06 microg. Samples from the upper surfaces of automobile motors were generally low to nondetectable (<0.027 microg/sample), while the median value of 0.047 mkcrlg/50 cm(2)(CV = 160%) and up to 0.640 microg were found on the drip pans.

Anthropometric evaluation of the Creches children furniture in Turkey.  

PubMed

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. PMID:17243561

A test rig for the measurement of vibration in hand-held power tools.  

PubMed

The purpose of the present project was to study the possibility of using a test rig for the measurement of vibration and noise from hand-held power tools. A test rig was designed to give the same effect on tool handle vibration as the human hand/arm system. Work was simulated by feeding the material to be processed against the tool, clamped into the rig, with the aid of a co-ordinate table. It was designed for use in studies of impact drills, chain saws, grinders and similar power tools. The report describes a proposal for testing the vibration properties of impact drills. Drilling with the test rig was compared with manual drilling. The difference in the acceleration level between the two methods was about 1 dB for ISO-weighted values in the critical direction. Both methods showed good reproducibility. The possibility of conducting noise level tests of a power tool in the rig was studied and the results are reported separately. PMID:15676459

Independence of data points in the measurement of hand preferences in primates: statistical problem or urban myth?  

PubMed

Lack of independence of data points or the pooling fallacy has been suggested as a potential problem in the study of handedness in nonhuman primates, particularly as it relates to whether hand use responses should be recorded as individual events or bouts of activity. Here, I argue that there is no evidence that the concept of statistical independence of data points or the pooling fallacy is a problem in the evaluation of population-level handedness in previous studies in nonhuman primates. I further argue these statistical concepts have been misapplied to the characterization of individual hand preferences. Finally, I argue that recording hand use responses as bouts rather than events has no significant effect on reports of hand use in nonhuman primates and, in fact, may unintentionally bias hand use toward the null hypothesis. Several suggestions for improvement in the measurement and statistical determination of individual handedness are offered in the article. PMID:23460350

Prevalence of ultrasound diagnosed nonalcoholic fatty liver disease among rural indigenous community of Sarawak and its association with biochemical and anthropometric measures.  

PubMed

Although the association between non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome has been previously firmly established, the prevalence of NAFLD and its risk factors in rural communities remains incompletely defined. This study aimed to determine the prevalence and factors associated with ultrasound-diagnosed NAFLD amongst a rural community in Sarawak. An indigenous village was randomly selected where all adults aged 21 years and above underwent an abdominal ultrasound, biochemical tests and an anthropometric assessment. Respondents with a score > or =8 on an alcohol-use disorders-identification test (AUDIT) indicating harmful or hazardous drinking were excluded. Seventy-seven respondents (46.8% male, mean age 48.4 SD 16.64), met inclusion criteria. The prevalence of ultrasound diagnosed NAFLD was 44.2% (n=34), among them 52.9% had moderate NAFLD. There were no significant age or gender differences between respondents with and without NAFLD, although those with NAFLD were older. Respondents with NAFLD had a significantly higher BMI t,han those without NAFLD (p<0.001). Both male and female respondents with NAFLD had a significantly higher waist circumference than those without NAFLD (p<0.001). Prevalence of diabetes, hypertension, hyperglycemia and hypertriglyceridemia were significantly higher among those with NAFLD. However, there were no significant differences in terms of percentage of unhealthy body fat and muscle, and serum HDL levels. Risk factors independently associated with NAFLD included male gender (odd ratio 0.06; 95% CI 0.008-0.523) and waist circumference (odd ratio 1.2; 95% CI 1.036-1.421). There was a high prevalence of NAFLD and the presence of more severe stages of disease in this indigenous population. Life-style related diseases, such as fatty liver disease, can occur in rural as well as urban populations. PMID:23691641

Continuing Measurements of CO2 Crystals with a Hand-Held 35 GHz Radiometer  

NASA Astrophysics Data System (ADS)

In order to increase our knowledge of the Martian polar caps, an improved understanding of the behavior of both frozen H2O and CO2 in different parts of the electromagnetic spectrum is needed. The thermal microwave part of the spectrum has received relatively little attention compared to the visible and infrared wavelengths. A simple experiment to measure the brightness temperature of frozen CO2 was first performed in the winter of 1998 using a 35 GHz radiometer. in experiments performed during the winter of 1999 and 2000, passive microwave radiation emanating from within layers of manufactured CO2 (dry ice) crystals was again measured with a 35 GHz handheld radiometer. Both large (0.8 cm) and small (0.3 cm) cylindrical-shaped dry ice pellets, at a temperature of 197 K (-76 C), were measured. A 1 sq m plate of aluminum sheet metal was positioned beneath the dry ice so that microwave emissions from the underlying soil layers would be minimized. Non-absorbing foam was positioned around the sides of the plate in order to keep the dry ice in place and to assure that the incremental deposits were level. Thirty-five GHz measurements of this plate were made through the dry ice deposits in the following way. Layers of dry ice were built up and measurements were repeated for the increasing CO2 pack. First, 7 cm of large CO2 pellets were poured onto the sheet metal plate, then an additional 7 cm were added, and finally, 12 cm were added on top of the 14 cm base. Hand-held 35 GHz measurements were made each time the thickness of the deposit was increased. The same process was repeated for the smaller grain pellets. Furthermore, during the past winter, 35 GHz measurements were taken of a 25 kg (27 cm x 27 cm x 27 cm) solid cube Of CO2, which was cut in half and then re-measured. Additional information is contained in the original extended abstract.

Determination of critical anthropometric parameters for design of respirators  

SciTech Connect

Anthropometric data were collected from 243 workers in a respirator fit-test programme, and an attempt was made to determine a correlation between these data and the Protection Factor obtained from quantitative fit-testing for half-mask respirators. Data were collected for two direct and five indirect facial measurements from front- and side-view slides of test subjects. For analysis, the data were normalized with relevant respirators dimensions (4 brands and 10 sizes). Results of linear regression analysis indicated that correlation coefficients between Protection Factor and anthropometric data (face length, mouth width, face width, nasal root breadth) were, respectively, 0.04, 0.22, 0.30 and 0.04. These correlation coefficients are for white males without facial hair. The analysis showed the 'critical' parameters to be mouth width and face width; however, a person with certain combinations of anthropometric parameters may provide a better correlation with Protection Factor.

Markerless motion capture and measurement of hand kinematics: validation and application to home-based upper limb rehabilitation.  

PubMed

Dynamic movements of the hand, fingers, and thumb are difficult to measure due to the versatility and complexity of movement inherent in function. An innovative approach to measuring hand kinematics is proposed and validated. The proposed system utilizes the Microsoft Kinect and goes beyond gesture recognition to develop a validated measurement technique of finger kinematics. The proposed system adopted landmark definition (validated through ground truth estimation against assessors) and grip classification algorithms, including kinematic definitions (validated against a laboratory-based motion capture system). The results of the validation show 78% accuracy when identifying specific markerless landmarks. In addition, comparative data with a previously validated kinematic measurement technique show accuracy of MCP ± 10° (average absolute error (AAE) = 2.4°), PIP ± 12° (AAE = 4.8°), and DIP ± 11° (AAE = 4.8°). These results are notably better than clinically based alternative manual measurement techniques. The ability to measure hand movements, and therefore functional dexterity, without interfering with underlying composite movements, is the paramount objective to any bespoke measurement system. The proposed system is the first validated markerless measurement system using the Microsoft Kinect that is capable of measuring finger joint kinematics. It is suitable for home-based motion capture for the hand and, therefore, achieves this objective. PMID:23475333

Relation of anthropometric variables to coronary artery disease risk factors  

PubMed Central

Background and Objectives: Anthropometric variables and their relation to conventional coronary artery disease (CAD) risk factors in railway employees have been inadequately studied in India. This cross-sectional survey was carried out in the Solapur division of the Central railway in the year 2004, to assess the anthropometric variables in railway employees and their relation to conventional CAD risk factors. Materials and Methods: A total of 995 railway employees, with 872 males and 123 females participated in this cross-sectional study. All subjects underwent anthropometric measurements, fasting lipid profile, and blood sugar level. Various anthropometric indices were calculated for body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and abdominal volume index (AVI). Statistical analysis was done by EPI Info 6 statistical software. Results: Compared to all other obesity indices, WHtR was most prevalent in both genders. High WHtR was present in 699 (80.16%) males and 103 (83.73%) females. Age ?45 years, high systolic BP, high diastolic BP, low HDL, high triglyceride, and diabetes mellitus were positively correlated with high BMI, high WC, high WHR, high WHtR, and high AVI. High BMI, high WC, high WHR, high WHtR, and high AVI were negatively associated with physical inactivity. Conclusions: Over all, anthropometric variables in both genders were significantly deranged in subjects with coronary risk factors. Compared to all other anthropometric variables, WHtR was statistically significantly associated with a majority of coronary artery risk factors. Hence we recommend inclusion of WHtR as a parameter of obesity to predict coronary artery disease risk factor along with WC, WHR, and BMI in epidemiologic studies.

Anthropometric and body composition characteristics among preschool children of Coastal, Himalayan and Desert Ecology in India.  

PubMed

The present cross-sectional study was aimed to compare anthropometric and body composition characteristics of preschool children in the three contrasting ecological niches namely Coastal, Himalayan and Desert Ecology. A total of 989 randomly selected children (aged < 6 years) in which 306 children (164 boys and 142 girls) belong to Coastal Ecology, 327 children (177 boys and 150 girls) belong to Himalayan Ecology and 356 children (168 boys and 188 girls) belong to Desert Ecology. Anthropometric measures namely height, weight, skinfolds at biceps, triceps, subscapular and suprailiac were measured for each child. Body mass index (BMI), sum of four skinfolds (SF4), trunk extremity ratio (TER), arm muscle circumference (AMC), arm muscle area (AMA) and arm fat area (AFA) was computed accordingly using standard equations. No significant sex difference was observed for the mean age within and between the groups. There existed significant sex differences for SF4, TER across the ecological zones. One way ANOVA with Scheffe's posthoc test revealed that Group II (Himalayan Ecology) had significantly higher means than both Group I (Coastal Ecology) and Group III (Desert Ecology) for BMI, SF4 and AFA. On the other hand, Group I had significantly higher means than Group II and Group III for TER (girls only), AMC and AMA. Percentiles (10th, 25th, 50th, 75th and 95th) were also calculated for anthropometric and body composition variables. It was observed that there existed significant sex differences for anthropometric and body composition variables both within (p < 0.05) and between (p < 0.001) the groups (ecological zones) except for AFA (p = 0.07). The 50th percentiles of BMI for Coastal, Himalayan and Desert Ecology were 11.65, 13.00 and 11.85, respectively. The 95th percentile of AFA was 4.81, 8.15 and 6.06 respectively. Significant group differences for variables reiterated the fact that ecology does influence nutrition and body composition measures through underlying physiology of growth. PMID:20405697

Performance of a new hand-held device for exhaled nitric oxide measurement in adults and children  

PubMed Central

Background Exhaled nitric oxide (NO) measurement has been shown to be a valuable tool in the management of patients with asthma. Up to now, most measurements have been done with stationary, chemiluminescence-based NO analysers, which are not suitable for the primary health care setting. A hand-held NO analyser which simplifies the measurement would be of value both in specialized and primary health care. In this study, the performance of a new electrochemical hand-held device for exhaled NO measurements (NIOX MINO) was compared with a standard stationary chemiluminescence unit (NIOX). Methods A total of 71 subjects (6–60 years; 36 males), both healthy controls and atopic patients with and without asthma were included. The mean of three approved exhalations (50 ml/s) in each device, and the first approved measurement in the hand-held device, were compared with regard to NO readings (Bland-Altman plots), measurement feasibility (success rate with 6 attempts) and repeatability (intrasubject SD). Results Success rate was high (? 84%) in both devices for both adults and children. The subjects represented a FENO range of 8–147 parts per billion (ppb). When comparing the mean of three measurements (n = 61), the median of the intrasubject difference in exhaled NO for the two devices was -1.2 ppb; thus generally the hand-held device gave slightly higher readings. The Bland-Altman plot shows that the 95% limits of agreement were -9.8 and 8.0 ppb. The intrasubject median difference between the NIOX and the first approved measurement in the NIOX MINO was -2.0 ppb, and limits of agreement were -13.2 and 10.2 ppb. The median repeatability for NIOX and NIOX MINO were 1.1 and 1.2 ppb, respectively. Conclusion The hand-held device (NIOX MINO) and the stationary system (NIOX) are in clinically acceptable agreement both when the mean of three measurements and the first approved measurement (NIOX MINO) is used. The hand-held device shows good repeatability, and it can be used successfully on adults and most children. The new hand-held device will enable the introduction of exhaled NO measurements into the primary health care.

Hand-handle interface force and torque measurement system for pneumatic assembly tool operations: suggested enhancement to ISO 6544.  

PubMed

A hand-handle interface force and torque measurement system is introduced to fill the void acknowledged in the international standard ISO 6544, which governs pneumatic, assembly tool reaction torque and force measurement. This system consists of an instrumented handle with a sensor capable of measuring grip force and reaction hand moment when threaded, fastener-driving tools are used by operators. The handle is rigidly affixed to the tool in parallel to the original tool handle allowing normal fastener-driving operations with minimal interference. Demonstration of this proposed system was made with tools of three different shapes: pistol grip, right angle, and in-line. During tool torque buildup, the proposed system measured operators exerting greater grip force on the soft joint than on the hard joint. The system also demonstrated that the soft joint demanded greater hand moment impulse than the hard joint. The results demonstrate that the measurement system can provide supplemental data useful in exposure assessment with power hand tools as proposed in ISO 6544. PMID:17454501

Medical impacts of anthropometric records.  

PubMed

Anthropology is now one of the inter-disciplinary scientific fields that is gaining much attention in forensic, socio-cultural, industrial and bio-medical applications. There is a need for a better awareness of some of the impacts--past and present, in the medical practice, of the records that were obtained by workers in this field in view of their proper applications, and future reference. Compilation of anthropometric works and records was conducted to evaluate the previous and current implications with the aim to highlight the importance of this seemingly old but yet evolving and dynamic subject and to elucidate its usefulness. However, despite the arduous efforts to get reliable data from anthropometric investigations, errors had most times characterized the concluding postulations of many workers in this field in the past, creating skepticism. But with better attention being given to the exercise, possible improvement in the methodology of the study with resultant authentic records and more reliable conclusion is anticipated.

A palmar pressure sensor for measurement of upper limb weight bearing by the hands during transfers by paraplegics.  

PubMed

Abstract Paraplegic patients have to effect transfer from one seat to another by using their upper limbs. In this process the hands bear almost the entire weight of the body in at least some phases of the transfer. It is desirable to train patients, especially those who are elderly and otherwise weak, to distribute their weight so as to avoid large forces being sustained on any one hand for an extended period. It is also desirable to evaluate the effectiveness of assistive devices like lower limb FES in sharing the load on the hand. This study presents a simple and versatile method of measuring palmar hand force during transfers by paraplegic patients. It is important that this force sensor should not interfere with the grasping and stabilizing properties of the hands and should permit normal transferring. The force sensor comprises an air-filled pouch or pillow that can be placed on any surface. This pneumatic sensor feels like upholstery padding on the surface on which it is placed. The sensor integrates the total pressure applied to the surface of the pouch, thereby obtaining the total force exerted by the palm/hand. The fabrication of the sensor is described, as well as the associated measurement circuit. The static calibration shows that the sensor is linear up to 350?N and the dynamic calibration shows that it has a bandwidth of 13?Hz. The sensor was fabricated using an inflated inelastic airbag attached to a pressure transducer. An automatic offset correction circuit in the preamplifier module ensures that any offset due to initial pressure or sensor drift is removed and the output is zero under no load condition. The key to this sensor arrangement is the ease of fitting it into the intended location without disturbing the existing arrangement for the subject's activities of daily living (ADL). PMID:23964668

Is three-dimensional anthropometric analysis as good as traditional anthropometric analysis in predicting junior rowing performance?  

PubMed

With the use of three-dimensional whole body scanning technology, this study compared the 'traditional' anthropometric model [one-dimensional (1D) measurements] to a 'new' model [1D, two-dimensional (2D), and three-dimensional (3D) measurements] to determine: (1) which model predicted more of the variance in self-reported best 2000-m ergometry rowing performance; and (2) what were the best anthropometric predictors of ergometry performance, for junior rowers competing at the 2007 and 2008 Australian Rowing Championships. Each rower (257 females, 16.3 ± 1.4 years and 243 males, 16.6 ± 1.5 years) completed a performance and demographic questionnaire, had their mass, standing and sitting height physically measured and were landmarked and scanned using the Vitus Smart® 3D whole body scanner. Absolute and proportional anthropometric measurements were extracted from the scan files. Partial least squares regression analysis, with anthropometric measurements and age as predictor variables and self-reported best 2000-m ergometer time as the response variable, was used to first compare the two models and then to determine the best performance predictors. The variance explained by each model was similar for both male [76.1% (new) vs. 73.5% (traditional)] and female [72.3% (new) vs. 68.6% (traditional)] rowers. Overall, absolute rather than proportional measurements, and 2D and 3D rather than 1D measurements, were the best predictors of rowing ergometry performance, with whole body volume and surface area, standing height, mass and leg length the strongest individual predictors.

Effects of tea combined with high-protein meal replacement shakes on anthropometric measurements, lipid profiles, cellular biochemistry, neurochemistry, and microbial metabolism: a prospective observational study  

PubMed Central

Objective The purpose of this study was to report preliminary data on the effects of tea and high-protein meal replacement shakes on weight loss, waist-to-hip ratios, and lipid profiles in healthy subjects. Secondary analyses of urine samples assessed pre-post changes in cellular biochemistry, neurochemistry, and microbial metabolism. Methods This study used a pre-post intervention design without a control group. Thirty healthy subjects (20-60 years of age; 23 women and 7 men) participated in a 28-day diet intervention program consisting of a cleansing day and 6 restricted diet days per week. On cleansing days, the subjects drank 4 oz of tea 4 times per day with a recommendation to drink at least 64 oz of filtered water. On the restricted diet days, the subjects drank 2 high-protein meal replacement shakes, consumed one 400- to 600-cal (1674.3-2511.5 joules) meal consisting of low–glycemic index foods, and drank at least 64 oz of filtered water. Results Multiple paired t tests detected reductions in weight (6.4 lb), waist (1.9 in), and hip (1.1 in) measurements and in total cholesterol (13.3 mg/dL) and low-density lipoprotein cholesterol (11.4 mg/dL) (P < .05). Multiple paired t tests detected significant increases in energy metabolism from carbohydrates and amino acids and concomitant increases in oxidative stress (P < .05). Conclusion The data support the concept that a low–glycemic load diet intervention incorporating tea and high-protein meal replacement shakes may cause weight loss and improve lipid profiles. The significant physiologic changes from the urine samples did not reflect meaningful metabolic effects.

VAT=TAAT-SAAT: Innovative Anthropometric Model to Predict Visceral Adipose Tissue Without Resort to CT-Scan or DXA  

PubMed Central

Objective To investigate whether a combination of a selected but limited number of anthropometric measurements predicts visceral adipose tissue (VAT) better than other anthropometric measurements, without resort to medical imaging. Hypothesis Abdominal anthropometric measurements are total abdominal adipose tissue indicators and global measures of VAT and SAAT (subcutaneous abdominal adipose tissue). Therefore, subtracting the anthropometric measurement the more correlated possible with SAAT while being the least correlated possible with VAT, from the most correlated abdominal anthropometric measurement with VAT while being highly correlated with TAAT, may better predict VAT. Design and Methods BMI participants' range was from 16.3 to 52.9 kg m?2. Anthropometric and abdominal adipose tissues data by computed tomography (CT-Scan) were available in 253 patients (18-78 years) (CHU Nord, Marseille) and used to develop the anthropometric VAT prediction models. Results Subtraction of proximal thigh circumference from waist circumference, adjusted to age and/or BMI, predicts better VAT (Women: VAT = 2.15 × Waist C ? 3.63 × Proximal Thigh C + 1.46 × Age + 6.22 × BMI ? 92.713; R2 = 0.836. Men: VAT = 6 × Waist C ? 4.41 × proximal thigh C + 1.19 × Age ? 213.65; R2 = 0.803) than the best single anthropometric measurement or the association of two anthropometric measurements highly correlated with VAT. Both multivariate models showed no collinearity problem. Selected models demonstrate high sensitivity (97.7% in women, 100% in men). Similar predictive abilities were observed in the validation sample (Women: R2 = 76%; Men: R2 = 70%). Bland and Altman method showed no systematic estimation error of VAT. Conclusion Validated in a large range of age and BMI, our results suggest the usefulness of the anthropometric selected models to predict VAT in Europides (South of France).

Association between a quantitative measure of tactile acuity and hand symptoms reported by operators of power tools.  

PubMed

An association between a quantitative measure of tactile acuity at the fingertips and symptoms of reduced manipulative function, as established by responses to a questionnaire, was demonstrated in a population of 81 manual workers from the mining industry (62 power-tool operators and 19 nonusers). Mechanoreceptor-specific vibrotactile thresholds were determined for the slowly adapting type I (SAI) and fast-adapting types I and II (FAI and FAII) receptors at the fingertip of the third digit of each hand. Statistically significant threshold shifts in SAI and/or FAII acuity were found in persons responding affirmatively to questions concerning finger/hand numbness, blanching, and difficulty buttoning clothing. The best predictors of a quantitative change in tactile acuity were questions relating to difficulty manipulating small objects and buttoning clothing, yielding positive predictive values of from 90% to 100% and false positive rates of from 0% to 2.8%. The demonstration of an association between a quantitative measure of tactile acuity at the fingertips and some symptom reports, obtained by means of a questionnaire, provides the basis for the development of a screening procedure for persons at risk of such disturbances in hand function.

A dexterity measure for the kinematic control of a multifinger, multifreedom robot hand  

SciTech Connect

This work examines the properties of the manifold generated as the configuration space of the linkage used for each finger of the Salisbury hand. The authors begin with an exhaustive catalog of design types for the finger based on an analysis of its branch loci. They then study the conditions under which the forward kinematic map becomes singular. These singularities define a submanifold that partitions the linkage's configuration space into a number of open sheets, each of which maps diffeomorphically onto a corresponding open region in the finger's reachable work space. Next they consider the determinant function of the finger's Jacobian matrix. The stationary points of this function reveal those configurations where the Jacobian determinant is a maximum. The Jacobian determinant can be thought of as an oriented volume in the tangent space to the finger's work space, and the orientation of this volume reveals the most favorable direction(s) for effecting tip motion or, reciprocally, for applying tip forces. From this they establish a simple criterion that can be used to find the optimal grasp configuration(s) for a given finite displacement of the workpiece.

Anthropometric risk factors for patellar tendon injury among volleyball players  

PubMed Central

Objective Abnormal imaging in the patellar tendon reveals pathology that is often associated with knee pain. Anthropometric measures of body size and mass, such as height, weight and waist?to?hip ratio (WHR), have been individually associated with abnormal imaging. The aim of this study was to investigate the anthropometric factors that have the strongest relationship with abnormal imaging in volleyball players. Methods Height, weight, body mass index (BMI), waist girth, hip girth and WHR were measured in a cohort of 113 competitive volleyball players (73 men, 40 women). The univariate (ANOVA) and multivariable (discriminant function analysis) association between abnormal imaging and these anthropometric factors were investigated. Results No significant association was found in the female volleyball players. A significant univariate association was observed between abnormal imaging and heavier weight, greater BMI, larger waist and hip girth and larger WHR in the male volleyball players. Waist girth was the only factor that retained this association in a multivariable model (p<0.05). Conclusions Men with a waist girth greater than 83?cm seem to be at greater risk of developing patellar tendon pathology. There may be both mechanical and biochemical reasons for this increased risk.

Dermal transfer of chlorpyrifos residues from residential surfaces: comparison of hand press, hand drag, wipe, and polyurethane foam roller measurements after broadcast and aerosol pesticide applications.  

PubMed Central

Indoor residential pesticide applications present the potential for human exposures, particularly for small children. Personal contact with target and nontarget surfaces can result in transfer of pesticides to the skin, but the magnitude of such transfer is uncertain. This research compared surface sampling techniques [wipe and polyurethane foam (PUF) roller] with the removal ability of human skin following broadcast and total aerosol release applications of Dursban (Dow Elanco, Midland, MI), a residential formulation containing the insecticide chlorpyrifos. Hands were washed immediately after surface contact, following a protocol that included a laboratory-generated adjustment factor to account for incomplete removal of chlorpyrifos from skin. Chlorpyrifos transfer was similar for hand press and hand drag techniques, averaging approximately 1-6 ng/cm2 of carpet contacted. These amounts represented < 1% of the amount of chlorpyrifos deposited on the surfaces 3.5 hr earlier. Chlorpyrifos transfer from carpet to skin was 23-24 times lower than for wipe sampling and 33-36 times lower than for PUF roller sampling (p = 0.0007 and p = 0.0006 for broadcast and aerosol applications, respectively). Hand press sampling removed approximately 4.5 times less chlorpyrifos from nontarget furniture surfaces (12 ng/cm2) than did wipe sampling (56 ng/cm2; p = 0.009). Chlorpyrifos residues on carpet were substantially higher after broadcast applications than after aerosol applications, but residues on such nontarget surfaces as furniture were substantially higher for the aerosol application. This study indicates that human skin removes substantially less residue from carpets and furniture than either conventional wipe or PUF roller sampling methods following residential pest control applications of chlorpyrifos. Although this paper focuses on quantifying residue transfer from surface to skin using different surface sampling techniques, no attempt is made to quantify the amount of chlorpyrifos residue that is subsequently absorbed.

[Occupational therapeutic measures before and after surgical correction of hands with congenital malformations].  

PubMed

The task of the occupational therapist following surgical procedures on deformed hands is discussed. In the child with congenital malformations, we must not only be concerned with treatment of the deformity but we must be concerned about the psychic problems which can develop following prolonged hospitalization or overprotection. One must be keenly observant to detect these problems early. Preoperative testing utilizing a standardized gripping test is carried out by the occupational therapist. The necessity for this is demonstrated by the example of the radial clubhand. In this way complications such as correction of clubhand in the face of a stiff elbow or pollicisation in the presence of inadequate clubhand correction can thus be avoided. After operation training in the new functions is begun as early as possible; preferably with individual supervision. Daily repetative and progressive exercises should result in maximum utilization of gripping ability provided by the operative procedure. The treatment program also includes the adaptation of clothing, the production of appliances and splints, in co-operation with the orthopedic technician, as well as specially designed functional exercises. All these factors are as important as the operative procedure itself in contributing to maximum benifit. All essential findings and their variations must be written down. Also the photographic documentation of the functions is the job of the occupational therapist. Sufficient time should be allowed prior to discharge to inform the parents about the newly acquired functions and the use of the applicances. The maintenance and further development of the newly acquired functions is insured through the continued ambulatory supervision by the doctor and the occupational therapist. The occupational therapist thus has a significant job as a member of the team in a special unit for children with congenital malformations. PMID:1201830

Iterative design and testing of a hand-held, non-contact wound measurement device.  

PubMed

A variety of wound measurement techniques are available to clinicians. Options range from relatively simple and inexpensive to complex, expensive devices. An iterative design approach was used to evaluate and improve performance and clinical utility of a new wound measurement device (WMD). The design was based upon a commercially available Smartphone. Accuracy was assessed using bench testing and reliability of area measurements was determined using multiple evaluators. Clinical utility was investigated by deploying the WMD during wound rounds in a rehabilitation hospital. Accuracy testing revealed an average error <2% at 0° or skew and an average error of 4.28% at 10° of skew. The intra-rater reliability exceeded 0.975 for all raters and inter-rater reliability was 0.966. Clinical utility testing provided the opportunity to address several usability concerns including the software interface and computation times. The accuracy and reliability of a new, non-contact wound measurement device exceeded that of other manual techniques and were, at least, equivocal to other computer-based technologies. Some limitations of using a Smartphone were identified by the clinicians that can be addressed by the more advanced processing power of newer technology. Overall, the WMD was shown to have the potential as a useful clinical tool. PMID:21945341

Improved facial outcome assessment using a 3D anthropometric mask.  

PubMed

The capacity to process three-dimensional facial surfaces to objectively assess outcomes of craniomaxillofacial care is urgently required. Available surface registration techniques depart from conventional facial anthropometrics by not including anatomical relationship in their analysis. Current registrations rely on the manual selection of areas or points that have not moved during surgery, introducing subjectivity. An improved technique is proposed based on the concept of an anthropometric mask (AM) combined with robust superimposition. The AM is the equivalent to landmark definitions, as used in traditional anthropometrics, but described in a spatially dense way using (?10.000) quasi-landmarks. A robust superimposition is performed to align surface images facilitating accurate measurement of spatial differences between corresponding quasi-landmarks. The assessment describes magnitude and direction of change objectively and can be displayed graphically. The technique was applied to three patients, without any modification and prior knowledge: a 4-year-old boy with Treacher-Collins syndrome in a resting and smiling pose; surgical correction for hemimandibular hypoplasia; and mandibular hypoplasia with staged orthognathic procedures. Comparisons were made with a reported closest-point (CP) strategy. Contrasting outcomes were found where the CP strategy resulted in anatomical implausibility whilst the AM technique was parsimonious to expected differences. PMID:22103995

Metabolic activity of sodium, measured by neutron activation, in the hands of patients suffering from bone diseases: concise communication  

SciTech Connect

Turnover of sodium in the human hand was studied by neutron activation. Patients suffering from various metabolic abnormalities affecting the skeleton, who were undergoing routine neutron activation for the measurement of calcium, were investigated along with a group of healthy volunteers. Neutron activation labels the sodium atoms simultaneously and with equal probability regardless of the turnover time of individual body compartments. The loss of sodium can be described either by a sum of two exponentials or by a single power function. Distinctions between patients and normal subjects were not apparent from the exponential model but were brought out by the power function. The exponent of time in the latter is a measure of clearance rate. The mean values of this parameter in (a) a group of patients suffering from acromegaly; (b) a group including Paget's disease, osteoporosis, Cushing's disease, and hyperparathyroidism; and (c) a group of healthy subjects, were found to be significantly different from each other.

Anthropometric characteristics and nutritional profile of young amateur swimmers.  

PubMed

The aim of this study was to evaluate nutritional and anthropometric profiles of young swimmers belonging to semiprofessional teams. Thirty-six caucasian adolescent swimmers (22 boys and 14 girls) participated voluntarily in the study. Anthropometric data, dietary intake, and blood parameters were determined. Female swimmers had greater values of triceps, suprailiac, and abdominal skinfolds. Endomorphic somatotype was twofold greater in girls compared with in boys. Energy intake and protein intake per kilogram of body weight were significantly greater in boys compared to in girls. On the other hand, girls had significantly greater polyunsaturated fatty acid intake compared that of boys. Energy intake of boys and girls was below their requirements. In contrast, protein intake doubled the requirements of the study population. Furthermore, inadequate intake of carotenes, vitamin A, vitamin E, vitamin D, and folic acid was found in both boys and girls; girls also had inadequate intake of iron and calcium. Plasma levels of iron, vitamins C and E, and carotenes were similar in male and females swimmers, and they were within the normal range. In conclusion, young swimmers participating in the present study had differences between sexes in somatotypes. Adolescent swimmers had low average total energy intakes, excessive protein intake, and lower intake of several micronutrients in both sexes. PMID:20838252

Reliability and validity of the figure-of-eight method of measuring hand size in patients with breast cancer-related lymphoedema.  

PubMed

Breast cancer-related lymphoedema (BCRL) affects 24-42% of patients following treatment for breast cancer. The gold standard method of measuring hand swelling associated with BCRL is to use water displacement (volumeter). This is not always possible in the clinical setting and the figure-of-eight method, which involves wrapping a simple measuring tape around the hand in a specific way, may be an alternative. The aim of the study was to examine the reliability and validity of the figure-of-eight method of measuring hand size in women with BCRL. Twenty-four patients with hand swelling associated with BCRL participated. Two novice testers performed three 'blinded' figure-of-eight measurements and three volumetric measurements of each hand. In terms of intertester (between-tester) and intratester (within-tester) reliability, the intraclass correlation coefficients were all greater than 0.8 indicating high intra- and intertester reliability for the figure-of-eight method. For validity, a Pearson's moment correlation computed between the figure-of-eight and volumetric methods highlighted a statistically significant correlation of 0.7 between the methods for both testers. The figure-of-eight method was found to be a valid and reliable method of measuring hand swelling in this population. PMID:23320995

Ethnicity-specific anthropometric predictors of metabolic risk in women.  

PubMed

OBJECTIVE: The objective of this study was to determine associations of anthropometric measures of thigh and abdominal adipose tissue with metabolic risk factors, and whether these associations differed with ethnicity. We hypothesized that thigh circumference (ThC) would have an independent favorable association with insulin sensitivity, lipids, and blood pressure, whereas waist circumference (WC) would have an independent deleterious association with these variables in both African Americans (AA) and European Americans (EA). METHODS: Subjects were 228 healthy, overweight, premenopausal AA and EA women. Insulin sensitivity was assessed by intravenous glucose tolerance test and minimal modeling. Simple relationships between anthropometric measures and risk factors were determined by Pearson correlation analysis. Partial correlation coefficients were determined for circumference measures adjusted for thigh and abdominal skinfolds to differentiate relationships between thigh and abdominal subcutaneous fat from thigh muscle and deeper abdominal fat, respectively. RESULTS: In EA but not AA, ThC was positively associated with insulin sensitivity, independent of thigh skinfold. In both EA and AA, ThC was associated with a desirable lipid profile. In AA but not EA, WC was associated with lower insulin sensitivity and a less desirable metabolic profile. CONCLUSION: Results suggest that thigh muscle (ThC adjusted for thigh skinfold) may be metabolically protective in EA but not AA. In contrast, WC was a better indicator of insulin sensitivity and metabolic health in AA. Further investigation is needed to verify the association between thigh muscle and metabolic health, and to probe the reason for the observed ethnic specificity of the associations between anthropometric measures and metabolic risk factors.

PubMed

The scope of this study was to evaluate the nutritional profile of indigenous Xukuru-Kariri villagers in the state of Minas Gerais between seven and seventy-eight years of age in accordance with the different anthropometric and body composition indicator. The measurements were: weight, height, waist circumference (WC) and body fat percentage (BF%). The sensitivity and specificity of anthropometric indices were calculated with a confidence interval of 95% and positive predictive value (PPV) and negative predictive value (NPV). A total of 58 individuals was evaluated, of which 56.9% (n =33) were male and 43.1% (n =25) were female. Specificity was greater than sensitivity in all indices. It was seen that 29% of individuals were classified as having excess body fat as assessed by BMI and hand-to-hand bioimpedance and 50% of subjects had high body fat in relation to BMI and WC. Studies need to be conducted with different ethnic groups in order to construct indicators for specific nutritional guidance of indigenous health services. PMID:23358766

Anthropometric approximation of body weight in unresponsive stroke patients  

PubMed Central

Background and purpose Thrombolysis of acute ischaemic stroke is based strictly on body weight to ensure efficacy and to prevent bleeding complications. Many candidate stroke patients are unable to communicate their body weight, and there is often neither the means nor the time to weigh the patient. Instead, weight is estimated visually by the attending physician, but this is known to be inaccurate. Methods Based on a large general population sample of nearly 7000 subjects, we constructed approximation formulae for estimating body weight from simple anthropometric measurements (body height, and waist and hip circumference). These formulae were validated in a sample of 178 consecutive inpatients admitted to our stroke unit, and their accuracy was compared with the best visual estimation of two experienced physicians. Results The simplest formula gave the most accurate approximation (mean absolute difference 3.1 (2.6)?kg), which was considerably better than the best visual estimation (physician 1: 6.5 (5.2)?kg; physician 2: 7.4 (5.7)?kg). It reduced the proportion of weight approximations mismatched by >10% from 31.5% and 40.4% (physicians 1 and 2, respectively) to 6.2% (anthropometric approximation). Only the patient's own estimation was more accurate (mean absolute difference 2.7 (2.4)?kg). Conclusions By using an approximation formula based on simple anthropometric measurements (body height, and waist and hip circumference), it is possible to obtain a quick and accurate approximation of body weight. In situations where the exact weight of unresponsive patients cannot be ascertained quickly, we recommend using this approximation method rather than visual estimation.

Measures of participation outcomes related to hand use for 2- to 12-year-old children with disabilities: a systematic review.  

PubMed

Many interventions have been used to improve children's hand-related impairments or hand skill performance in functional activities so as to promote life participation. There is thus a need to have suitable instruments assessing children's participation in life situations that specifically require hand use in order to support and evaluate such interventions. This systematic review investigated the availability of potential instruments that can be used to assess children's participation specifically in life situations requiring hand use. Clinical utility and evidence for psychometric properties were also sourced. Database searches initially identified measures that were used to evaluate participation of children aged 2-12 years, involved self- or proxy report or interview administration and had generic application for a range of disabilities/diagnoses. These measures were further evaluated to determine if they fulfilled the above inclusion criteria and contained at least 60% of the items involving hand use. Further searches for psychometric evidence were undertaken for the eligible measures. Fourteen measures were identified and nine met the inclusion criteria. However, none of these measures, except for the Children Helping Out: Responsibilities, Expectations, and Supports (CHORES), contained all items related to hand use. Most of the included measures had limited psychometric properties. Only the Children's Assessment of Participation and Enjoyment/Preferences for Activities of Children (CAPE/PAC), the School Function Assessment-Participation section (SFA-P) and the Children Participation Questionnaire (CPQ) revealed sufficient evidence of validity and reliability. The findings suggest a need for adapting existing participation measures or developing new ones that specifically assess participation in life situations requiring hand use to support interventions.

Quenching and Cold-Work Residual Stresses in Aluminum Hand Forgings : Contour Method Measurement and FEM Prediction  

SciTech Connect

The cold-compression stress relief process used to reduce the quench-induced stresses in high-strength aerospace aluminum alloy forgings does not fully relieve the stresses. This study measured and predicted the residual stress in 7050-T74 (solution heat treated, quenched, and artificially overaged) and 7050-T7452 (cold compressed prior to aging) hand forgings. The manufacturing process was simulated by finite element analysis. First, a thermal analysis simulated the quench using appropriate thermal boundary conditions and temperature dependent material properties. Second, a structural analysis used the thermal history and a temperature and strain-rate dependent constitutive model to predict the stresses after quenching. Third, the structural analysis was continued to simulate the multiple cold compressions of the stress relief process. Experimentally, the residual stresses in the forgings were mapped using the contour method, which involved cutting the forgings using wire EDM and then measuring the contour of the cut surface using a CMM. Multiple cuts were used to map different stress components. The results show a spatially periodic variation of stresses that results from the periodic nature of the cold work stress relief process. The results compare favorably with the finite element prediction of the stresses.

Metabolic and anthropometric changes with weight cycling in wrestlers.  

PubMed

Repeated cycles of weight loss and regain have come to be known as weight cycling. This phenomenon is frequently observed in athletes who must meet specific weight categories to qualify for competition. The purpose of this study was to determine the metabolic and anthropometric changes that occur with rapid weight loss/regain cycles in competitive wrestlers. Collegiate wrestlers were divided into two groups, "cyclers" (N = 8) and "noncyclers" (N = 6), based on their reported dieting history. Measurements included a 3-d diet record, resting energy expenditure (REE), skinfold and girth measures, and biochemical tests at three time points: preseason, peak season, and off-season. All anthropometric measures changed with time, and a diet group by time interaction was observed for the trunk to extremity skinfolds ratio (T/E) (P < 0.05), with greater fat loss and regain from the trunk area of the cyclers. There were no differences in REE within or between groups. Serum triiodothyronine (T3) values decreased over time (P < 0.01). Large weight losses appear to have occurred due to both dieting and short-term dehydration, and although physiological changes were observed, a training effect may have overridden any metabolic influence of weight cycling.

Anthropometric and physiological characteristics of junior elite volleyball players  

PubMed Central

Objectives To investigate the anthropometric and physiological characteristics of junior elite volleyball players. Method Twenty five national level volleyball players (mean (SD) age 17.5 (0.5) years) were assessed on a number of physiological and anthropometric variables. Somatotype was assessed using the Heath?Carter method, body composition (% body fat, % muscle mass) was assessed using surface anthropometry, leg strength was assessed using a leg and back dynamometer, low back and hamstring flexibility was assessed using the sit and reach test, and the vertical jump was used as a measure of lower body power. Maximal oxygen uptake was predicted using the 20?m multistage fitness test. Results Setters were more ectomorphic (p<0.05) and less mesomorphic (p<0.01) than centres. Mean (SD) of somatotype (endomorphy, mesomorphy, ectomorphy) for setters and centres was 2.6 (0.9), 1.9 (1.1), 5.3 (1.2) and 2.2 (0.8), 3.9 (1.1), 3.6 (0.7) respectively. Hitters had significantly greater low back and hamstring flexibility than opposites. Mean (SD) for sit and reach was 19.3 (8.3)?cm for opposites and 37 (10.7)?cm for hitters. There were no other significant differences in physiological and anthropometric variables across playing positions (all p>0.05). Conclusion Setters tend to be endomorphic ectomorphs, hitters and opposites tend to be balanced ectomorphs, whereas centres tend to be ectomorphic mesomorphs. These results indicate the need for sports scientists and conditioning professionals to take the body type of volleyball players into account when designing individualised position specific training programmes.

Throwing velocities, anthropometric characteristics, and efficacy indices of women's European water polo subchampions.  

PubMed

Water polo is a team sport characterized by a high-intensity, intermittent activity, where technical and tactical aspect are of a great importance. For that reason, the main aim of this study was to define the anthropometrical characteristics, maximum isometric grip strength, training and competition throwing velocities, and the efficacy indices in female high-level water polo players. A second purpose was to examine the differences between the throwing velocities in training vs. European championships in the water polo female national team. Ten elite trained female water polo players participated in this study. Before the competitive phase of their season, the following measures were taken: standard anthropometry, static and dynamic training throwing velocities, and hand-grip dynamometry. In the competitive phase, efficacy indices, average and maximum throwing velocities from all the participants were also determined. Significant differences (p ? 0.05) were found between different training situations and different competitive throwing velocities. We concluded that elite female water polo players modify their throwing velocity depending if the throw is performed during training or competitive situation. PMID:21993039

Measuring the effects of manipulating stimulus presentation time on sensorimotor alpha and low beta reactivity during hand movement observation.  

PubMed

The present study addresses three methodological questions that have been ignored in previous research on EEG indices of the human mirror neuron system (hMNS), particularly in regard to autistic individuals. The first question regards how to elicit the EEG indexed hMNS during movement observation: Is hMNS activation best elicited using long stimulus presentations or multiple short repetitions? The second question regards what EEG sensorimotor frequency bands reflect sensorimotor reactivity during hand movement observation? The third question regards how widespread is the EEG reactivity over the sensorimotor cortex during movement observation? The present study explored sensorimotor alpha and low beta reactivity during hand movement versus static hand or bouncing balls observation and compared two experimental protocols (long exposure vs. multiple repetitions) in the same participants. Results using the multiple repetitions protocol indicated a greater low beta desynchronisation over the sensorimotor cortex during hand movement compared to static hand and bouncing balls observation. This result was not achieved using the long exposure protocol. Therefore, the present study suggests that the multiple repetitions protocol is a more robust protocol to use when exploring the sensorimotor reactivity induced by hand action observation. In addition, sensorimotor low beta desynchronisation was differently modulated during hand movement, static hand and bouncing balls observation (non-biological motion) while it was not the case for sensorimotor alpha and that suggest that low beta may be a more sensitive index of hMNS activation during biological motion observation. In conclusion the present study indicates that sensorimotor reactivity of low beta during hand movement observation was found to be more widespread over the sensorimotor cortex than previously thought.

Birth order influence on the anthropometric properties of the boys from Tuzla region (Bosnia and Herzegovina).  

PubMed

Birth order and its effect on growth and development of children and youths have rarely been studied so far. The objective of this research was an analysis of the birth order effects on some anthropometric properties of the boys 11-16 years old. The sample consisted of 748 boys from the Tuzla region. As the sample included very few boys born as the third, forth, or fifth child, we decided to consider only the differences in the mean values for some anthropometric parameters between the groups of the first- and the second-born. Measurements were taken according to IBP and the following parameters were investigated: body height, body mass, chest circumference, upper arm circumference, upper leg circumference, sitting height, arm length, leg length, pelvis width, shoulders width, length and width of head. We established that in most generations the firstborn boys have larger mean values for most anthropometric variables in comparison to the second-born. PMID:15629024

Coordination of hand shape.  

PubMed

The neural control of hand movement involves coordination of the sensory, motor, and memory systems. Recent studies have documented the motor coordinates for hand shape, but less is known about the corresponding patterns of somatosensory activity. To initiate this line of investigation, the present study characterized the sense of hand shape by evaluating the influence of differences in the amount of grasping or twisting force, and differences in forearm orientation. Human subjects were asked to use the left hand to report the perceived shape of the right hand. In the first experiment, six commonly grasped items were arranged on the table in front of the subject: bottle, doorknob, egg, notebook, carton, and pan. With eyes closed, subjects used the right hand to lightly touch, forcefully support, or imagine holding each object, while 15 joint angles were measured in each hand with a pair of wired gloves. The forces introduced by supporting or twisting did not influence the perceptual report of hand shape, but for most objects, the report was distorted in a consistent manner by differences in forearm orientation. Subjects appeared to adjust the intrinsic joint angles of the left hand, as well as the left wrist posture, so as to maintain the imagined object in its proper spatial orientation. In a second experiment, this result was largely replicated with unfamiliar objects. Thus, somatosensory and motor information appear to be coordinated in an object-based, spatial-coordinate system, sensitive to orientation relative to gravitational forces, but invariant to grasp forcefulness.

Hand-Held Tidal Breathing Nasal Nitric Oxide Measurement - A Promising Targeted Case-Finding Tool for the Diagnosis of Primary Ciliary Dyskinesia  

PubMed Central

Background Nasal nitric oxide (nNO) measurement is an established first line test in the work-up for primary ciliary dyskinesia (PCD). Tidal breathing nNO (TB-nNO) measurements require minimal cooperation and are potentially useful even in young children. Hand-held NO devices are becoming increasingly widespread for asthma management. Therefore, we chose to assess whether hand-held TB-nNO measurements reliably discriminate between PCD, and Healthy Subjects (HS) and included Cystic Fibrosis (CF) patients as a disease control group known to have intermediate nNO levels. Methods In this cross sectional, single centre, single occasion, proof-of-concept study in children and adults with PCD and CF, and in HS we compared feasibility, success rates, discriminatory capacity, repeatability and agreement between a hand-held electrochemical device equipped with a nNO software application sampling at flow rates 2 ml/s or 5 ml/s, and two stationary chemiluminescence devices, applying both tidal breathing and velum closure techniques. Results Measurements were done in 16 PCD patients, 21 patients with CF and 20 HS aged between 3.8 and 60.9 years. Hand-held TB-nNO showed high success rate (96.5–100%) vs. velum closure nNO techniques (70.2–89.5%). Hand-held TB-nNO sampling at flow rate 5 ml/s showed equally high discriminative power (PCD vs. HS [p<0.0001] and PCD vs. CF [p<0.0001]) and reaching close to 100% sensitivity and specificity, superior repeatability (CV%?=?10%) and equal limits of agreement compared to TB-nNO by stationary devices and even compared to velum closure sampling. Conclusion Hand-held TB-nNO discriminates significantly between PCD, CF and HS and shows promising potential as a widespread targeted case-finding tool for PCD, although further studies are warranted before implementation.

Association of Anthropometric indexes with chronic kidney disease in a Chinese population.  

PubMed

Objective: Obesity is associated with an increased risk of chronic kidney disease (CKD), but the best anthropometric obesity measure remains controversial. This study aimed to examine the associations of anthropometric indexes with CKD risk and which anthropometric index is a better predictor of CKD. Methods: Data was drawn from a cross-sectional study in China. We used four anthropometric indexes: body mass index (BMI), waist circumference (WC), waist-tohip ratio (WHR), and waist-to-height ratio (WHtR). CKD was defined as estimated glomerular filtration rate (eGFR) < 60 ml/ min/1.73 m2 or urinary albumin to creatinine ratio (ACR) ? 30 mg/g. Logistic regressions were used for the analyses. Results: 1,834 participants were included in the analyses. After adjusting for potential confounders, BMI, WC and WHtR were significantly associated with CKD in men and women. The respective odd ratios for BMI (every SD increment), WC (every SD increment), and WHtR (every SD increment) were 1.46, 1.40, and 1.45 in men as well as 1.21, 1.31, and 1.38 in women. After adjusting for potential confounders, WHR was associated with CKD in women but not men. In women, the associations of WC, WHR and WHtR with CKD was independent of other MetS components. No difference in WHtR was observed between men and women. Conclusion: Anthropometric indexes are associated with CKD. The associations of anthropometric indexes with CKD are independent of other MetS components in women but not men. In women, central obesity indexes are better than BMI for predicting of CKD. *Both authors contributed equally. PMID:24091315

An anthropometric model to estimate neonatal fat mass using air displacement plethysmography  

PubMed Central

Background Current validated neonatal body composition methods are limited/impractical for use outside of a clinical setting because they are labor intensive, time consuming, and require expensive equipment. The purpose of this study was to develop an anthropometric model to estimate neonatal fat mass (kg) using an air displacement plethysmography (PEA POD® Infant Body Composition System) as the criterion. Methods A total of 128 healthy term infants, 60 females and 68 males, from a multiethnic cohort were included in the analyses. Gender, race/ethnicity, gestational age, age (in days), anthropometric measurements of weight, length, abdominal circumference, skin-fold thicknesses (triceps, biceps, sub scapular, and thigh), and body composition by PEA POD® were collected within 1-3 days of birth. Backward stepwise linear regression was used to determine the model that best predicted neonatal fat mass. Results The statistical model that best predicted neonatal fat mass (kg) was: -0.012 -0.064*gender + 0.024*day of measurement post-delivery -0.150*weight (kg) + 0.055*weight (kg)2 + 0.046*ethnicity + 0.020*sum of three skin-fold thicknesses (triceps, sub scapular, and thigh); R2 = 0.81, MSE = 0.08 kg. Conclusions Our anthropometric model explained 81% of the variance in neonatal fat mass. Future studies with a greater variety of neonatal anthropometric measurements may provide equations that explain more of the variance.

Effects of vehicle interior geometry and anthropometric variables on automobile driving posture.  

PubMed

The effects of vehicle package, seat, and anthropometric variables on posture were studied in a laboratory vehicle mockup. Participants (68 men and women) selected their preferred driving postures in 18 combinations of seat height, fore-aft steering wheel position, and seat cushion angle. Two seats differing in stiffness and seat back contour were used in testing. Driving postures were recorded using a sonic digitizer to measure the 3D locations of body landmarks. All test variables had significant independent effects on driving posture. Drivers were found to adapt to changes in the vehicle geometry primarily by changes in limb posture, whereas torso posture remained relatively constant. Stature accounts for most of the anthropometrically related variability in driving posture, and gender differences appear to be explained by body size variation. Large intersubject differences in torso posture, which are fairly stable across different seat and package conditions, are not closely related to standard anthropometric measures. The findings can be used to predict the effects of changes in vehicle and seat design on driving postures for populations with a wide range of anthropometric characteristics. PMID:11324849

Analysis of performance of prepubertal swimmers assessed from anthropometric and bio-energetic characteristics.  

PubMed

The relationship between anthropometric and bio-energetic data and timed performance over 50 to 400 m was studied in 25 young male swimmers [11.3 (SD 1) years]. Anthropometric measurements included height, body mass, body fat mass, body area, thoracic section area (Ats) thoracic circumferences, lengths of upper limb, bi-acromial and bi-iliac diameters. Maximal oxygen consumption (VO2max; direct method), maximal anaerobic power (W(an),max; force-velocity test) and mean power in 30 s sprint (W30 s; Wingate test) were also measured. Each of these bio-energetic variables was expressed in absolute terms, relating to body mass, body area and Ats. The stepwise regression method was used to determine contribution of the variables (anthropometric and/or bio-energetic) of the time achieved over the distance. The W30 s/Ats accounted for 46% of the time over 50 m (negative correlation). The VO2max/Ats and height were negatively correlated with the times of performances over 100 m, 200 m and 400 m, these two variables accounted for 71% to 77% of the performance. These results would indicate that even in young boys, anthropometric and bio-energetic characteristics are both important in swimming performance, particularly the bio-energetic variables expressed per Ats.

Various human and animal studies suggest that changes in Mg status are linked to diseases such as cardiac arrhythmia, coronary heart disease, hypertension, premenstrual syndrome, and diabetes mellitus. Thus, knowledge of Mg levels in the human body is needed. A direct measurement of human blood serum, which contains only 0.3% of the total body Mg, is generally used to infer information about the status of Mg in the body. However, in many clinical situations, Mg stored in large levels, for example in bones, muscles, and soft tissues, needs to be monitored either to evaluate the efficacy of a treatment or to study the progression of diseases associated with the deficiency of total body Mg. This work presents a feasibility study of a noninvasive, in vivo neutron activation analysis (IVNAA) technique using the {sup 26}Mg(n,{gamma}){sup 27}Mg reaction to measure Mg levels in human hands. The technique employs the McMaster University high beam current Tandetron accelerator hand irradiation facility and an array of eight NaI (T1) detectors arranged in a 4{pi} geometry for delayed counting of the 0.844 and 1.014 MeV gamma rays emitted when {sup 27}Mg decays in the irradiated hand. Mg determination in humans using IVNAA of hands has been demonstrated to be feasible, with effective doses as low as one-quarter of those delivered in chest x rays. The overall experimental uncertainty in the measurements is estimated to be approximately 5% (1{sigma}). The results are found to be in the range of the in vitro measurements reported for other cortical bones collected from different sites of the human skeleton, which confirms that this technique mainly provides a measure of the amount of Mg in hand bones. The average concentration of Mg determined in human hands is 10.96{+-}1.25 ({+-}1 SD) mg Mg/g Ca. The coefficient of variation (11%) observed in this study is comparable with or lower than several studies using in vitro measurements reported in the literature and therefore allows for a quantitative intersubject comparison, even if to a limited extent. The features of the developed technique such as its simplicity, rapidity, accuracy, robustness, noninvasive nature, and very effective use of radiation doses, present the technique as a viable diagnostic tool available for trial in a clinical environment.

[Hand wounds].  

PubMed

Hand wounds represent a major problem in regard of the number of patients as well as the economic burden associated with it. The close relationship of the different anatomical structures increase the probability of involvement of multiple structures, which require a multidisciplinary approach. Paucity of clinical signs of certain lesions render surgical exploration necessary. Regarding replantation, multiple factors need to be taken into consideration, principally the condition of the amputated part, which is influenced by the trauma but also by the initial care applied to the severed part. Transfer delay to a specialized center should be minimize. PMID:20085204

Prediction of anthropometric accommodation in aircraft cockpits  

NASA Astrophysics Data System (ADS)

Designing aircraft cockpits to accommodate the wide range of body sizes existing in the U.S. population has always been a difficult problem for Crewstation Engineers. The approach taken in the design of military aircraft has been to restrict the range of body sizes allowed into flight training, and then to develop standards and specifications to ensure that the majority of the pilots are accommodated. Accommodation in this instance is defined as the ability to: (1) Adequately see, reach, and actuate controls; (2) Have external visual fields so that the pilot can see to land, clear for other aircraft, and perform a wide variety of missions (ground support/attack or air to air combat); and (3) Finally, if problems arise, the pilot has to be able to escape safely. Each of these areas is directly affected by the body size of the pilot. Unfortunately, accommodation problems persist and may get worse. Currently the USAF is considering relaxing body size entrance requirements so that smaller and larger people could become pilots. This will make existing accommodation problems much worse. This dissertation describes a methodology for correcting this problem and demonstrates the method by predicting pilot fit and performance in the USAF T-38A aircraft based on anthropometric data. The methods described can be applied to a variety of design applications where fitting the human operator into a system is a major concern. A systematic approach is described which includes: defining the user population, setting functional requirements that operators must be able to perform, testing the ability of the user population to perform the functional requirements, and developing predictive equations for selecting future users of the system. Also described is a process for the development of new anthropometric design criteria and cockpit design methods that assure body size accommodation is improved in the future.

Relationship between balance performance in the elderly and some anthropometric variables.  

PubMed

Ability to maintain either static or dynamic balance has been found to be influenced by many factors such as height and weight in the elderly. The relationship between other anthropometric variables and balance performance among elderly Nigerians has not been widely studied. The aim of this study was to investigate the relationship between these other anthropometric variables and balance performance among old individuals aged >60 years in Ibadan, Nigeria. The study used the ex-post facto design and involved two hundred and three apparently healthy (103 males and 100 females) elderly participants with ages between 60 years and 74 years, selected using multiple step-wise sampling techniques from churches, mosques and market place within Ibadan. They were without history of neurological problem, postural hypotension, orthopeadic conditions or injury to the back and/or upper and lower extremities within the past one year. Selected anthropometric variables were measured, Sharpened Romberg Test (SRT) and Functional Reach Test (FRT) was used to assess static balance and dynamic balance respectively. All data were summarized using range, mean and standard deviation. Pearson's product moment correlation coefficient was used to determine the relationship between the physical characteristics, anthropometric variables and performance on each of the two balance tests. The results showed that there were low but significant positive correlations between performance on FRT and each of height, weight, trunk length, foot length, shoulder girth and hip girth. (p<0.05). There was low significant and positive correlation between SRT with eyes closed and arm length, foot length and shoulder girth. (p<0.05) and there was low but significant positive correlation between SRT with eyes opened and shoulder girth and foot length (P<0.05). Anthropometric variables affect balance performances in apparently healthy elderly. PMID:19301708

Anthropometric protocols for the construction of new international fetal and newborn growth standards: the INTERGROWTH-21st Project.  

PubMed

The primary aim of the INTERGROWTH-21(st) Project is to construct new, prescriptive standards describing optimal fetal and preterm postnatal growth. The anthropometric measurements include the head circumference, recumbent length and weight of the infants, and the stature and weight of the parents. In such a large, international, multicentre project, it is critical that all study sites follow standardised protocols to ensure maximal validity of the growth and nutrition indicators used. This paper describes, in detail, the selection of anthropometric personnel, equipment, and measurement and calibration protocols used to construct the new standards. Implementing these protocols at each study site ensures that the anthropometric data are of the highest quality to construct the international standards. PMID:23841804

Kinematics and force analysis of a robot hand based on an artificial biological control scheme  

NASA Astrophysics Data System (ADS)

An artificial biological control scheme (ABCS) is used to study the kinematics and statics of a multifingered hand with a view to developing an efficient control scheme for grasping. The ABCS is based on observation of human grasping, intuitively taking it as the optimum model for robotic grasping. A final chapter proposes several grasping measures to be applied to the design and control of a robot hand. The ABCS leads to the definition of two modes of the grasping action: natural grasping (NG), which is the human motion to grasp the object without any special task command, and forced grasping (FG), which is the motion with a specific task. The grasping direction line (GDL) is defined to determine the position and orientation of the object in the hand. The kinematic model of a redundant robot arm and hand is developed by reconstructing the human upper extremity and using anthropometric measurement data. The inverse kinematic analyses of various types of precision and power grasping are studied by replacing the three-link with one virtual link and using the GDL. The static force analysis for grasping with fingertips is studied by applying the ABCS. A measure of grasping stability, that maintains the positions of contacts as well as the configurations of the redundant fingers, is derived. The grasping stability measure (GSM), a measure of how well the hand maintains grasping under the existence of external disturbance, is derived by the torque vector of the hand calculated from the external force applied to the object. The grasping manipulability measure (GMM), a measure of how well the hand manipulates the object for the task, is derived by the joint velocity vector of the hand calculated from the object velocity. The grasping performance measure (GPM) is defined by the sum of the directional components of the GSM and the GMM. Finally, a planar redundant hand with two fingers is examined in order to study the various postures of the hand performing pinch grasping by applying the GSM and the GMM.

Variation of the Anthropometric Index for pectus excavatum relative to age, race, and sex  

PubMed Central

OBJECTIVES: To determine possible variations in the Anthropometric Index for pectus excavatum relative to age, race, and sex in individuals free of thoracic wall deformities. METHODS: Between 2002 and 2012, 166 individuals with morphologically normal thoracic walls consented to have their chests and the perimeter of the lower third of the thorax measured according to the Anthropometric Index for pectus excavatum. The participant characteristics are presented (114 men and 52 women; 118 Caucasians and 48 people of African descent). RESULTS: Measurements of the Anthropometric Index for pectus excavatum were statistically significantly different between men and women (11–40 years old); however, no significant difference was found between Caucasians and people of African descent. For men, the index measurements were not significantly different across all of the age groups. For women, the index measurements were significantly lower for individuals aged 3 to 10 years old than for individuals aged 11 to 20 years old and 21 to 40 years old; however, no such difference was observed between women aged 11 to 20 years old and those aged 21 to 40 years old. CONCLUSION: In the sample, significant differences were observed between women aged 11 to 40 years old and the other age groups; however, there was no difference between Caucasian and people of African descent.

Multiparametric Body Composition Analysis and Anthropometric Empirical Indicator: Obesity based South Indian Perspective.  

PubMed

Background: Obesity has emerged to be global threat to mankind. Many abnormalities such as Cardiovascular Diseases, Diabetes emerge as outcomes of obesity. Objectives: The present study aimed at bringing out a technique, which considers the combinational measurement of all essential anthropometric circumferences and BMI, so that the accurate assessment of obesity can be made. Till date, BMI has been considered to be the main adiposity index. But, the distribution of body fat was not taken into account by BMI. The contradictory outcomes by BMI pertaining to risk factor detection in various ethnicities and populations were witnessed. Also, BMI failed to gauge obesity in muscular body builders who possess small waists and large torsos Materials and Methods: The study adopted cross-sectional design in which 107 subjects from urban south India were participated. The measurements of body composition and anthropometry were manifested on the studied population. Results: The higher significant difference of ?0.001 was witnessed in male and female studied population, when AEI (BIA1), AEI (EXTERNAL) and BMI were compared against BFM (measured by both the devices BIA1 and BIA2). Conclusion: The results exhibited the prominence of AEI {Anthropometric Empirical Indicator, which is the combinational measurement of all essential anthropometric circumferences and BMI} over BMI.Also,the validity of the effective functioning of low cost,portable,simple protocol based body composition analyzer on par with the higher cost, standard body composition analyzer was demonstrated by the present study.

Mechanical cornpicker hand injuries.  

PubMed

Mechanical cornpicker hand injuries are not frequent in comparison to general hand trauma, but they have a specific mechanism of occurrence and are very severe. This investigation included 221 hand injuries. The sex distribution shows a general male dominance (85.25%) in their active age (84.44%). These are, seasonal injuries mostly occurring in October (75.11%). By type of injuries, mutilating crush injuries are most frequent (64.25%). After completing the treatment, in most cases the functional result were estimated as bad (50.68%). Data concerning education and trainig for operating agricultural machines (96.38%--patients without training) and carrying out safety measures (63.35% of injured patients did not apply any protection measures) are devastating. The number of these injuries, as well as consequent permanent disabilities, may be considerably reduced by preventive measures, inclulding public health services and media. Use of contempoarary agricultural machinery, as well as obligatory training for operating these machines and application of protective measures, may also reduce the incidence of hand injuries during corn picking.

The zygomaticomaxillary complex fracture - an anthropometric appraisal of surgical outcomes.  

PubMed

Before undergoing repair of zygomaticomaxillary complex fractures, most patients are worried about their postoperative appearance. Furthermore, there is an ongoing discussion about the selection of the surgical approach to the inferior orbita and resulting eyelid deformities. We present a photo-assisted postoperative evaluation of zygomaticomaxillary complex fracture repair based on reference anthropometric data. Two hundred and twenty-one patients underwent zygomaticomaxillary complex fracture repair. An analysis of standardized postoperative photographs included measurements of eye fissure width and height, lid sulcus height, upper lid height, upper and lower coverage, position of cornea to palpebra inferior, canthal tilt, scleral show, ectropion and entropion. It was clearly distinguished between operated and contralateral eyelid, and whether a transconjunctival or a subciliary approach was performed. Surgery per se significantly influenced eyelid deformities as measured by its impact on eye fissure index, lower iris coverage and rate of scleral show and ectropion. The surgical approach selected significantly affected eye fissure index, lower iris coverage and rate of scleral show, indicating distortion of the lower eyelid. Investigations regarding orbital fractures should clearly differentiate the type of fracture. The subciliary approach included the highest risk of postoperative lower eyelid deformity in zygomaticomaxillary complex fracture repair. The standardized measurements described here are accurate and objective to evaluate postoperative results. PMID:23218980

The San Antonio Biethnic Children's Blood Pressure Study: anthropometric findings.  

PubMed

Cardiovascular diseases and diabetes are very prevalent today, and early detection of the precursors of these diseases is important. Increased weight and body mass indexes (BMIs) are known to be risk factors for these adult diseases. The objectives of this portion of the study were to obtain anthropometric measurements known to correlate with children's blood pressure levels and to compare these measurements among Mexican-American (M-A) females and males and non-Hispanic white (W) females and males. These data will allow healthcare providers to know normal weights and BMIs for different ethnic groups so that early detection of risk factors can be done. Anthropometric measurements (weight, height, BMI, subscapular and triceps skinfold thickness, and arm circumference) were obtained on 4,195 M-A and 2,039 W children in kindergarten through 12th grade in two school districts in the San Antonio, Texas, area. Data were statistically analyzed and related to age. M-A males had a tendency to be heavier than W males throughout the ages studied. M-A females had a tendency to be heavier than W females until 11 years of age, but that trend was reversed between ages 14 and 18. For all four subgroups, there was a marked skewness toward obesity based on BMI (kg/m2). Height of M-A children beginning as early as 5 years of age was slightly but significantly (P > or = .05) less than that of W children of the same gender. M-A males and females had either a tendency for or significantly higher values (P > or = .05) for BMI than W counterparts. M-A children had larger subscapular and triceps skinfold thickness than their W counterparts, with females showing greater values than males. The data indicate that there are several important differences in weight, height, BMI, and skinfold thickness between M-A and W children and between boys and girls as noted above. There are also considerable increases in weight with a relatively stable height in all four subgroups since the last published growth charts. PMID:10476088

Anthropometric and training data have been reported as statistically significant predictors of race performance in endurance events. However, it is well established that physiological characteristics, i.e., maximal oxygen uptake (VO2max), the use of a high percentage of VO2max during sustained exercise, and work efficiency are predominant predictors of performance in those events. Thus, the essential issue is whether the anthropometric and training data give additional predictive power beyond these other measures. PMID:24032337

Hand Anthropometry and SMS Satisfaction  

NASA Astrophysics Data System (ADS)

The effect of hand anthropometry on Short Message Service (SMS) satisfaction was investigated using structured questionnaire interviews with 110 subjects, aged between 17-25 years old. Hand size was measured to assess its effect on mobile phone design factors satisfaction whereas thumb circumference and length were measured for keypad design factors. Small hand-sized subjects were found to be more satisfied with mobile phone dimensions than large hand-sized subjects. Thumb circumference significantly affects users` satisfaction towards key size and space between keys whereas thumb length significantly affects keypad layout satisfaction. Both thumb circumference and length significantly correlate negatively with the corresponding keypad design factors. Results confirm that hand anthropometry do affect users messaging satisfaction. These findings should prove useful to mobile phone designers who could look into the possibility of designing customized mobile phones that cater to large hand and thumb sized users, so as to increase their subjective satisfaction.

Means for some of the variables measured include: age, 29 yr; height, 180 cm; weight, 84 kg; lean body weight, 74 kg; body fat, 12%, endurance sit-ups, 50/min; vertical jump height, 51 cm; anaerobic power output, 132 m.kg.s-1 (1.32 kw); anaerobic capacity, 2247 m.kp/40s (22.5 kJ); maximum heart rate, 186 beats/min; maximum ventilation, 175 l/min-1; maximum respiratory quotient 1.23; and maximum oxygen uptake, 56.6 ml.kg-1 min-1. In comparison with other rugby players studied these players had higher maximum oxygen uptake values, were similar in endurance sit-up and vertical jump ability, exhibited less upper body strength, and the forwards had lower body fat percentages. They were generally within the range of scores found to describe the aerobic and anaerobic fitness, and body composition of other élite amateur and professional intermittent sport athletes.

The influence of arthritis on the anthropometric parameters of the feet of older women.  

PubMed

Age-related and arthritis-related foot modifications have been described in literature, but there is a lack of references that allow shoes to be designed on the basis of specific anthropometric measurements of older women. The aim of this study was to identify the anthropometric characteristics of the feet of elderly women with and without arthritis. This is an observational transversal study. The right and left feet of 227 older women aged between 60 and 90 years (69.6 + or - 6.8 years) were evaluated, of whom 45 reported a diagnosis of arthritis (non-osteoarthritis). The anthropometric evaluation of the feet comprised the variables of width, perimeter, height, foot length, first and fifth metatarsophalangeal angles, the arch-index and the foot posture index (FPI). The data were analyzed using the analysis of probability to compare the groups (arthritic and non-arthritic women). The differences between the means were significant in the case of the FPI and some of its criteria, such as the calcaneal frontal plane position, the bulge in the region of the talo-navicular joint and the forefoot alignment. The width of the right foot was also significantly greater in the women with arthritis. These results are preliminary findings that may help direct larger studies of foot characteristics among older adults with arthritis. PMID:19349085

Nonlinear relationships between anthropometric and physical fitness variables in untrained pubescent boys.  

PubMed

Previous studies evidently actualized nonlinear regressions as a step forward in defining the true nature of the relationships between anthropometric and physical fitness (PF) variables in trained subjects. In this paper we have sampled 1176 nontrained boys aged 14-16 years and tested them on (1) five anthropometric predictors, including: body height, body weight, triceps skinfold, upper arm circumference, and body mass index (BMI); and (2) five PF criteria measuring: static (static strength) and dynamic muscle endurance (repetitive strength), aerobic endurance, explosive strength, and coordination. Linear (y = a + bx) and nonlinear (second-order polynomial: y = a + bx + cx2) regressions were calculated simultaneously. BMI is found to be the most significant anthropometric predictor of PF status. Although the calculation and interpretation of nonlinear regressions are far more complicated in comparison to those of linear regressions, the variance of the criteria are in some cases far better explained through a significant nonlinear model. Even more, we have found evidence that an exclusive discussion of the linear correlation model could lead to serious interpretative mistakes. This mostly relates to the fact that a linear regression model implies a continuous relationship (dependence) between the predictor and the criteria, while a nonlinear one effectively identifies possible breakpoints in the regression line and consequently highlights the real nature of the relationship between variables.

Anthropometric and physiological characteristics in young afro-Caribbean swimmers. A preliminary study.  

PubMed

The authors investigated the anthropometric and physiological characteristics of young Guadeloupian competitive swimmers in relation to swimming performance and compared the abilities of these children with those of the young white swimmers reported in the literature. All 2004 competitive swimmers between 10 and 14 y old (126 children, 61 boys and 65 girls, 12.0 ± 1.3 y) from Guadeloupe underwent anthropometric measurements and physiological and performance testing. Six boys on the French national swimming team are referred to hereafter as the 2011 elite subgroup. Anthropometric parameters, a jump-and-reach test, glide, and estimated aerobic power (eVO2max) were assessed in terms of swimming-performance analysis through a 400-m test. This study demonstrated that the Guadeloupian swimmers had more body fat than most age-matched white swimmers but had very poor hydrostatic lift; they had higher peak jump height and they swam as well as their white counterparts. The variability in 400-m performance between subjects was best described by glide, age, and eVO2max. Compared with the group of boys with the same age, the 2011 elite subgroup was significantly better for arm span, peak jump height, glide, and 400-m and 15-m performances. Further research is needed to investigate motor organization and energy cost of swimming in Afro-Caribbean swimmers. PMID:23006763

Dietary patterns and anthropometric indices among Iranian women with major depressive disorder.  

PubMed

Major depression is a common mental disorder among women. A number of studies have demonstrated the association between some nutrients and food items with depression, but the studies on the association of dietary patterns with depression, especially in the Middle East, are rare. Further, the literature examining the relationship between anthropometric status and depression are inconsistent. In this study, 45 women with major depression and 90 patients with no mental disorder participated. We collected dietary intakes by a semi-quantitative food frequency questionnaire, and measured anthropometric indices (weight, height, waist and hip circumferences). Using factor analysis, two major dietary patterns were extracted: Healthy and Unhealthy. After adjusting for confounders, individuals who gained higher scores in healthy dietary pattern, had 84% lower odds of major depression; while the odds of major depression in participants who gained higher scores in unhealthy dietary pattern showed no significant association. No significant association was found between anthropometric indices and major depression. These results suggest that the healthy dietary pattern is significantly associated with lower odds of major depression in adult women. Further researches are needed to confirm these findings.

Anthropometric Profile and Special Judo Fitness levels of Indian Judo Players  

PubMed Central

Purpose Judo is a complex sport where different anthropological parameters determine performance. Judo, as a sport is not well known in India. There is evident lack of data concerning the anthropological determinants of judo players. This study was conducted to determine the anthropometric profile and Special Judo Fitness levels of judokas. Methods This cross sectional study was conducted on 31 judo players. Anthropometric profile was assessed by measuring height, weight, body mass index, body circumferences at seven sites, seven site skin fold thickness and body fat percentage as per standard accepted protocol. Special Judo Fitness Test – a specific test to evaluate the judo athlete's physical condition was applied. Statistical analysis done using Student's unpaired ‘t’ test and correlation by Karl Pearson's correlation coefficient. Results Out of 31 judo players 20 had ?5 yrs of judo practice (A group) and 11 >5 yrs of judo (B group). Anthropometric findings of both the judo groups were the same. Body fat has negative correlation (r =-0.690, P<0.05) with performance in SJFT. Observations during and after special judo fitness test were also similar. Conclusions Long term training has a minimal effect on anthropometry. Judo athletes of similar age when submitted to the same training type tend to show equal performance in the game and fitness levels after certain years of training. We also confirm existence of negative correlation between body fat and performance.

Female anthropometric variability and their effects on predicted thermoregulatory responses to work in the heat.  

PubMed

The use of thermoregulatory models for assessing physiological responses of workers in thermally stressful situations has been increasing because of the risks and costs related to human studies. In a previous study (Yokota et al. Eur J Appl Physiol 104:297-302, 2008), the effects of anthropometric variability on predicted physiological responses to heat stress in U.S. Army male soldiers were evaluated. Five somatotypes were identified in U.S. Army male multivariate anthropometric distribution. The simulated heat responses, using a thermoregulatory model, were different between somatotypes. The present study further extends this line of research to female soldiers. Anthropometric somatotypes were identified using multivariate analysis [height, weight, percent body fat (%BF)] and the predicted physiological responses to simulated exercise and heat stress using a thermoregulatory model were evaluated. The simulated conditions included walking at ~3 mph (4.8 km/h) for 300 min and wearing battle dress uniform and body armor in a 30°C, 25% relative humidity (RH) environment without solar radiation. Five major somatotypes (tall-fat, tall-lean, average, short-lean, and short-fat), identified through multivariate analysis of anthropometric distributions, showed different tolerance levels to simulated heat stress: lean women were predicted to maintain their core temperatures (T(c)) lower than short-fat or tall-fat women. The measured T(c) of female subjects obtained from two heat studies (data1: 30°C, 32% RH, protective garments, ~225 w·m(-2) walk for 90 min; data2: 32°C, 75% RH, hot weather battle dress uniform, ~378?±?32 w·m(-2) for 30 min walk/30 min rest cycles for 120 min) were utilized for validation. Validation results agreed with the findings in this study: fat subjects tended to have higher core temperatures than medium individuals (data2) and lean subjects maintained lower core temperatures than medium subjects (data1).

Physiological, Biomechanical and Anthropometrical Predictors of Sprint Swimming Performance in Adolescent Swimmers  

PubMed Central

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. Key points This 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 (90.3% of variability in performance), followed by anthropometrical (45.8%) and physiological (45.2%) parameters. Two selected variables (stroke index and stroke rate) explained 92.6% of the variance in competitive performance in these adolescent swimmers.

Objectively-assessed outcome measures: a translation and cross-cultural adaptation procedure applied to the Chedoke McMaster Arm and Hand Activity Inventory (CAHAI)  

PubMed Central

Background Standardised translation and cross-cultural adaptation (TCCA) procedures are vital to describe language translation, cultural adaptation, and to evaluate quality factors of transformed outcome measures. No TCCA procedure for objectively-assessed outcome (OAO) measures exists. Furthermore, no official German version of the Canadian Chedoke Arm and Hand Activity Inventory (CAHAI) is available. Methods An eight-step for TCCA procedure for OAO was developed (TCCA-OAO) based on the existing TCCA procedure for patient-reported outcomes. The TCCA-OAO procedure was applied to develop a German version of the CAHAI (CAHAI-G). Inter-rater reliability of the CAHAI-G was determined through video rating of CAHAI-G. Validity evaluation of the CAHAI-G was assessed using the Chedoke-McMaster Stroke Assessment (CMSA). All ratings were performed by trained, independent raters. In a cross-sectional study, patients were tested within 31 hours after the initial CAHAI-G scoring, for their motor function level using the subscales for arm and hand of the CMSA. Inpatients and outpatients of the occupational therapy department who experienced a cerebrovascular accident or an intracerebral haemorrhage were included. Results Performance of 23 patients (mean age 69.4, SD 12.9; six females; mean time since stroke onset: 1.5 years, SD 2.5 years) have been assessed. A high inter-rater reliability was calculated with ICCs for 4 CAHAI-G versions (13, 9, 8, 7 items) ranging between r = 0.96 and r = 0.99 (p < 0.001). Correlation between the CAHAI-G and CMSA subscales for hand and arm was r = 0.74 (p < 0.001) and r = 0.67 (p < 0.001) respectively. Internal consistency of the CAHAI-G for all four versions ranged between ? = 0.974 and ? = 0.979. Conclusions The TCCA-OAO procedure was validated regarding its feasibility and applicability for objectively-assessed outcome measures. The resulting German CAHAI can be used as a valid and reliable assessment for bilateral upper limb performance in ADL in patients after stroke.

Development and validation of anthropometric equations to estimate appendicular muscle mass in elderly women  

PubMed Central

Objective This study aimed to examine the cross validity of two anthropometric equations commonly used and propose simple anthropometric equations to estimate appendicular muscle mass (AMM) in elderly women. Methods Among 234 physically active and functionally independent elderly women, 101 (60 to 89 years) were selected through simple drawing to compose the study sample. The paired t test and the Pearson correlation coefficient were used to perform cross-validation and concordance was verified by intraclass correction coefficient (ICC) and by the Bland and Altman technique. To propose predictive models, multiple linear regression analysis, anthropometric measures of body mass (BM), height, girth, skinfolds, body mass index (BMI) were used, and muscle perimeters were included in the analysis as independent variables. Dual-Energy X-ray Absorptiometry (AMMDXA) was used as criterion measurement. The sample power calculations were carried out by Post Hoc Compute Achieved Power. Sample power values from 0.88 to 0.91 were observed. Results When compared, the two equations tested differed significantly from the AMMDXA (p <0.001 and p?=?0.001). Ten population / specific anthropometric equations were developed to estimate AMM, among them, three equations achieved all validation criteria used: AMM (E2)?=?4.150 +0.251 [bodymass (BM)] - 0.411 [bodymass index (BMI)]?+?0.011 [Right forearm perimeter (PANTd) 2]; AMM (E3)?=?4.087?+?0.255 (BM) - 0.371 (BMI)?+?0.011 (PANTd) 2 - 0.035 [thigh skinfold (DCCO)]; MMA (E6)?=?2.855?+?0.298 (BM)?+?0.019 (Age) - 0,082 [hip circumference (PQUAD)]?+?0.400 (PANTd) - 0.332 (BMI). The equations estimated the criterion method (p?=?0.056 p?=?0.158), and explained from 0.69% to 0.74% of variations observed in AMMDXA with low standard errors of the estimate (1.36 to 1.55 kg) and high concordance (ICC between 0,90 and 0.91 and concordance limits from -2,93 to 2,33 kg). Conclusion The equations tested were not valid for use in physically active and functionally independent elderly women. The simple anthropometric equations developed in this study showed good practical applicability and high validity to estimate AMM in elderly women.

[Body proportions in sculpture and painting. An anthropometric and historical essay (author's transl)].  

PubMed

Taking anthropometric mean values of the European population as a standard, we examined some proportions in representative sculptural and pictorial works of art. We established that the classical antique sculptures and those of Michelangelo and his school conform very closely to the European norm. Mid-Italian wooden crucifixes of the fourteenth and fifteenth centuries and early medieval European paintings of the Corpus Christi, on the other hand, display quite different proportions: exaggerated length of forearms, or torsos that are stunted in relationship to the legs. Proportions similar to these can be found in the art of the New Kingdom of the Egyptians, reflecting the physique of the Nubian population. We discussed the extent to which an artistic proportion is conditioned by style, imitation, racial aesthetic ideals, or anatomy of the ambient population. PMID:339875

The Rubber Hand Illusion: Feeling of Ownership and Proprioceptive Drift Do Not Go Hand in Hand  

PubMed Central

In the Rubber Hand Illusion, the feeling of ownership of a rubber hand displaced from a participant's real occluded hand is evoked by synchronously stroking both hands with paintbrushes. A change of perceived finger location towards the rubber hand (proprioceptive drift) has been reported to correlate with this illusion. To measure the time course of proprioceptive drift during the Rubber Hand Illusion, we regularly interrupted stroking (performed by robot arms) to measure perceived finger location. Measurements were made by projecting a probe dot into the field of view (using a semi-transparent mirror) and asking participants if the dot is to the left or to the right of their invisible hand (Experiment 1) or to adjust the position of the dot to that of their invisible hand (Experiment 2). We varied both the measurement frequency (every 10 s, 40 s, 120 s) and the mode of stroking (synchronous, asynchronous, just vision). Surprisingly, with frequent measurements, proprioceptive drift occurs not only in the synchronous stroking condition but also in the two control conditions (asynchronous stroking, just vision). Proprioceptive drift in the synchronous stroking condition is never higher than in the just vision condition. Only continuous exposure to asynchronous stroking prevents proprioceptive drift and thus replicates the differences in drift reported in the literature. By contrast, complementary subjective ratings (questionnaire) show that the feeling of ownership requires synchronous stroking and is not present in the asynchronous stroking condition. Thus, subjective ratings and drift are dissociated. We conclude that different mechanisms of multisensory integration are responsible for proprioceptive drift and the feeling of ownership. Proprioceptive drift relies on visuoproprioceptive integration alone, a process that is inhibited by asynchronous stroking, the most common control condition in Rubber Hand Illusion experiments. This dissociation implies that conclusions about feelings of ownership cannot be drawn from measuring proprioceptive drift alone.

Specific absorption rate levels measured in a phantom head exposed to radio frequency transmissions from analog hand-held mobile phones  

SciTech Connect

Electric fields (E-fields) induced within a phantom head from exposure to three different advanced mobile phone system (AMPS) hand-held telephones were measured using an implantable E-Field probe. Measurements were taken in the eye nearest the phone and along a lateral scan through the brain from its center to the side nearest the phone. During measurement, the phones were positioned alongside the phantom head as in typical use and were configured to transmit at maximum power (600 mW nominal). The specific absorption rate (SAR) was calculated from the in situ E-field measurements, which varied significantly between phone models and antenna configuration. The SARs induced in the eye ranged from 0.007 to 0.21 W/kg. Metal-framed spectacles enhanced SAR levels in the eye by 9--29%. In the brain, maximum levels were recorded at the measurement point closest to the phone and ranged from 0.12 to 0.83 W/kg. These SARs are below peak spatial limits recommended in the US and Australian national standards and the IRPA guidelines for safe exposure to radio frequency (RF) electromagnetic fields. Furthermore, a detailed thermal analysis of the eye indicated only a 0.022 C maximum steady-state temperature rise in the eye from a uniform SAR loading of 0.21 W/kg. A more approximate thermal analysis in the brain also indicated only a small maximum temperature rise of 0.034 C for a local SAR loading of 0.83 W/kg.

Effects of warming up on reliability of anthropometric techniques in ankylosing spondylitis.  

PubMed

To determine the effect of warm-up on anthropometric measures, 10 patients with ankylosing spondylitis and 10 normal control subjects were measured over a 1-hour period by one therapist. A series of 4 measures--a modified Schober's test, finger-to-floor with the subject standing on a 23-cm stool, chest expansion, and cervical rotation using an arthrodial protractor--were repeated completely 4 times. Subjects exercised between each series (except between the third and fourth series). Intra-rater reliability was determined by comparing measurement 3 with measurement 4, and the warm-up effect was determined by comparing measurement 1 with measurement 3. The Schober's test and chest expansion are stable measures and are not affected by warm-up. However, the finger-to-floor and cervical rotation exercises require warm-up to ensure stable values for clinical or research followup of spondylitis. PMID:3358812

Anthropometric measurements by ethnicity in Colombia, 1965-1990.  

PubMed

We analyzed the evolution of height in Colombia of cohorts born in the period 1965-1990 by ethnic groups. We found that Afro-Colombian men and women were the tallest: 6cm taller than indigenous people and 2cm taller than the rest of the population. We also found that the height gap between Afro-Colombians and others decreased during the period under study by 0.7cm for both men and women. While improvements were noticeable among the Afro-Colombians and those who chose not to be classified by ethnicity, in the case of the indigenous population only female cohorts registered an average-height increase of 1.5cm. Moreover, we found that indigenous Colombians were more likely than other ethnic groups to experience an increase in biological well-being as a consequence of an improvement in their socio-economic status, thereby reducing the average-stature gap between them and the rest of the population by 2.1 and 3.6cm for men and women, respectively.

Anthropometric Correlates of Total Body Fat, Abdominal Adiposity, and Cardiovascular Disease Risk Factors in a Biracial Sample of Men and Women  

PubMed Central

Objective To investigate associations between anthropometric measurements and total body fat, abdominal adipose tissue, and cardiovascular disease risk factors in a large biracial sample. Patients and Methods This study is limited to cross-sectional analyses of data from participants attending a baseline visit between January 26, 1996, and February 1, 2011. The sample included 2037 individuals aged 18 to 69 years: 488 African American women (24%), 686 white women (34%), 196 African American men (9%), and 667 white men (33%). Anthropometry included weight; hip circumference; waist circumference; waist-hip, waist-height, and weight-height ratios; body adiposity index; and body mass index. Body fat and percentage of fat were measured by dual-energy x-ray absorptiometry, and abdominal visceral and subcutaneous adipose tissue were measured by computed tomography. Bivariate correlations, logistic regression models, and receiver operator characteristic curves were used, and analyses were stratified by sex and race. Results In each sex-by-race group, all anthropometric measures were highly correlated with percentage of fat, fat mass, and subcutaneous adipose tissue and moderately correlated with visceral adipose tissue, with the exception of the waist-hip ratio. The odds of having an elevated cardiometabolic risk were increased more than 2-fold per SD increase for most anthropometric variables, and the areas under the curve for each anthropometric measure were significantly greater than 0.5. Conclusion Several common anthropometric measures were moderately to highly correlated with total body fat, abdominal fat, and cardiovascular disease risk factors in a biracial sample of women and men. This comprehensive analysis provides evidence of the linkage between simple anthropometric measurements and the purported pathways between adiposity and health.

Relationship between serum leptin level and laboratory and anthropometric indices of malnutrition in patients on hemodialysis  

PubMed Central

Protein-energy malnutrition is a major problem and one of the risk factors for mortality in hemodialysis patients. There is no single index in evaluation of nutritional status in these patients, so leptin can be used as one of the parameters. In this study, the correlation between serum leptin with biochemical and anthropometric parameters of nutrition has been evaluated. This cross-sectional study has been performed on 60 hemodialysis patients (32 males and 28 females) in 2006. The patients on hemodialysis for under 1 year and who has a history of consumption of lipid lowering agents or glucocorticoids, or an infectious or inflammatory disease were excluded. Malnutrition laboratory parameters and serum leptin were measured before hemodialysis. Serum leptin was measured with enzyme-linked immunosorbent assay (ELISA) method with direct dbc kit and malnutrition laboratory parameters measured with standard laboratory methods, patients anthropometric parameters evaluated after hemodialysis. The mean age of patients was 47.5 ± 16.1 years and the range of serum leptin level was 0.6-64.8 ng/ml. Mean serum leptin level were 22.64 ± 19.54 ng/ml in females and 16.74 ± 20.16 ng/ml in males on hemodialysis and in spite of higher level of leptin in females there was not any statistically significant difference between females and males serum leptin. Absolute value of correlation coefficient between serum leptin and anthropometric parameters and most laboratory parameters was < 0.25 (except ferritin, iron, phosphorous in males and total protein, hemoglobin, urea, and creatinin in females which was between 0.25 and 0.50). Our results suggest that the increased serum leptin level does not have a major role in diagnosis of malnutrition in hemodialysis patients and there is a poor correlation between malnutrition parameters and serum leptin level.

Comparison of carcinogen, carbon monoxide, and ultrafine particle emissions from narghile waterpipe and cigarette smoking: Sidestream smoke measurements and assessment of second-hand smoke emission factors  

NASA Astrophysics Data System (ADS)

The lack of scientific evidence on the constituents, properties, and health effects of second-hand waterpipe smoke has fueled controversy over whether public smoking bans should include the waterpipe. The purpose of this study was to investigate and compare emissions of ultrafine particles (UFP, <100 nm), carcinogenic polyaromatic hydrocarbons (PAH), volatile aldehydes, and carbon monoxide (CO) for cigarettes and narghile (shisha, hookah) waterpipes. These smoke constituents are associated with a variety of cancers, and heart and pulmonary diseases, and span the volatility range found in tobacco smoke. Sidestream cigarette and waterpipe smoke was captured and aged in a 1 m 3 Teflon-coated chamber operating at 1.5 air changes per hour (ACH). The chamber was characterized for particle mass and number surface deposition rates. UFP and CO concentrations were measured online using a fast particle spectrometer (TSI 3090 Engine Exhaust Particle Sizer), and an indoor air quality monitor. Particulate PAH and gaseous volatile aldehydes were captured on glass fiber filters and DNPH-coated SPE cartridges, respectively, and analyzed off-line using GC-MS and HPLC-MS. PAH compounds quantified were the 5- and 6-ring compounds of the EPA priority list. Measured aldehydes consisted of formaldehyde, acetaldehyde, acrolein, methacrolein, and propionaldehyde. We found that a single waterpipe use session emits in the sidestream smoke approximately four times the carcinogenic PAH, four times the volatile aldehydes, and 30 times the CO of a single cigarette. Accounting for exhaled mainstream smoke, and given a habitual smoker smoking rate of 2 cigarettes per hour, during a typical one-hour waterpipe use session a waterpipe smoker likely generates ambient carcinogens and toxicants equivalent to 2-10 cigarette smokers, depending on the compound in question. There is therefore good reason to include waterpipe tobacco smoking in public smoking bans.

Neuromuscular mechanisms and anthropometric modifications in the initial stages of independent gait.  

PubMed

The gait acquisition is an important milestone of motor development. Structural modifications observed during this period add complexity to the process, and the child needs to use appropriate neuromuscular strategies to walk independently. The objective of this study was to document the longitudinal modifications in neuromuscular mechanisms and in functional anthropometric measures during independent gait acquisition in typically developing children. Twelve children were followed for 2 months after gait acquisition, with its initial period documented by the standardized test Alberta Infant Motor Scale. Quantification of the EMG signals of six muscles in the right lower limb allowed the calculation of the co-contraction indexes (CCI) considering pairs of antagonistic muscles, representing the hip, knee and ankle joints. The CCIs were summed up to yield a total index. Anthropometric measures were transformed into gravitational torque (mLg) values for stance and swing phases of gait. Statistical analyses included repeated measures ANOVA models with one factor (week post-acquisition) for the dependent variables mLg and normalized CCI (CCI/mLg). A significant increase was observed in the mLg during the period evaluated both in stance and swing phases (p=0.0001). In addition, there was a decrease in the value of the normalized hip and total CCIs in both phases of gait (p<0.05). The results revealed changes in the neuromuscular mechanisms used by typical children to deal with the demands involved in the process of gait acquisition. PMID:16412641

Evaluating accuracy of structural geometry by DXA methods with an anthropometric proximal femur phantom.  

PubMed

DXA-derived bone structural geometry has been reported extensively but lacks an accuracy standard. In this study, we describe a novel anthropometric structural geometry phantom that simulates the proximal femur for use in assessing accuracy of geometry measurements by DXA or other X-ray methods. The phantom consists of seven different interchangeable neck modules with geometries that span the range of dimensions in an adult human proximal femur, including those representing osteoporosis. Ten repeated hip scans of each neck module using two current DXA scanner models were performed without repositioning. After scanner specific calibration, hip structure analysis was used to derive structural geometry. Scanner performance was similar for the two manufacturers. DXA-derived HSA geometric measurements were highly correlated with values derived directly from phantom geometry and position; R(2) between DXA and phantom measures were greater than 94 % for all parameters, while precision error ranged between 0.3 and 3.9 %. Despite high R(2) there were some systematic geometry errors for both scanners that were small for outer diameter, but increasing with complexity of geometrical parameter; e.g. buckling ratio. In summary, the anthropometric phantom and its fabrication concept were shown to be appropriate for evaluating proximal femoral structural geometry in two different DXA systems. PMID:23836197

Evaluation of anthropometric accuracy and reliability using different three-dimensional scanning systems.  

PubMed

The aim of this study was to evaluate the accuracy and reliability of standard anthropometric linear measurements made with three different three-dimensional scanning systems namely laser surface scanning (Minolta Vivid 900), cone beam computed tomography (CBCT), 3D stereo-photogrammetry (Di3D system) and to compare them to physical linear measurements. The study sample consisted of seven cadaver heads. The reliability and accuracy were assessed by means of a series of 21 standardized, linear facial measurements derived from 15 landmarks taken both directly on the face with a set of digital callipers and indirectly from a three-dimensional (3D) soft tissue surface models derived from CBCT, laser surface scans and 3D photographs. Statistical analysis for the reliability was done by means of intraclass correlation coefficients (ICCs). Accuracy was determined by means of the absolute error (AE) and absolute percentage error (APE) by comparison of the 3D measurements to the physical anthropometrical measurements. All the 3D scanning systems were proved to be very reliable (ICC>0.923-0.999) when compared to the physical measurements (ICC; 0.964-0.999). Only one CBCT measurement (t-g) and one Di3D measurement (t-sn left) had a mean AE of more than 1.5mm. There are clear potential benefits of using 3D measurements appose to direct measurements in the assessment of facial deformities. Measurements recorded by the three 3D systems appeared to be both sufficiently accurate and reliable enough for research and clinical use. PMID:20951517

Just clean your hands: Measuring the effect of a patient safety initiative on driving transformational change in a health care system.  

PubMed

In 2007, the Ontario government introduced the Just Clean Your Hands program across all provincial hospitals. The goal of this patient safety initiative was to improve hand hygiene practices among health care providers through workplace culture change. A survey questionnaire was distributed to 729 nurses employed at a single large community-based hospital from April to July 2011. Of the 223 nurses who responded to the questionnaire, 153 had completed the program (exposed group). By using the other 70 nurses as a contemporaneous control group (nonexposed), this study demonstrates that the Just Clean Your Hands program contributed to improved hand hygiene practices, but we were unable to demonstrate positive changes in patient safety culture.

Anthropometric data base for power plant design. Special report  

SciTech Connect

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.

Anthropometric evaluation for primary school furniture design.  

PubMed

Musculoskeletal symptoms are one of the top ten health problems among schoolchildren in Hong Kong. Whether or not these symptoms are related to school furniture has yet to be determined and published data on furniture size are lacking. The purpose of the study was to determine whether the design of furniture in schools is appropriate for children's anthropometry. A total of 214 volunteer subjects were recruited. This constituted 90% of the total number of primary 5 and 6 students in the studied school (i.e. those aged 10 and 13 years). The data collected included demographic information, data on perceived health and posture and body and furniture measurements. The girls' BMI was lower than that of the boys. The girls had longer lower limbs and wider hip breadth measurements in the standing position. This was similar in the sitting position. Almost none of the subjects had a chair with an appropriate seat height. Seat depth was found appropriate for large groups of students whether or not a large or small chair was used. Recommendations on the sizes of chairs and desks for boys and girls are discussed. PMID:17536771

The Effects of Body Acupuncture on Obesity: Anthropometric Parameters, Lipid Profile, and Inflammatory and Immunologic Markers  

PubMed Central

A randomized controlled clinical trial in 196 obese subjects was performed to examine the effectiveness of body acupuncture on body weight loss, lipid profile and immunogenic and inflammatory markers. Subjects received authentic (cases) or sham (controls) acupuncture for 6 weeks in combination with a low-calorie diet. In the following 6 weeks, they received the low-calorie diet alone. Subjects were assessed at the beginning, 6 and 12 weeks later. Heat shock protein (Hsps)-27, 60, 65, 70 antibody titers and high sensitivity C-reactive protein (hs-CRP) levels were also assessed. A significant reduction in measures of adiposity and improvement in lipid profile were observed in both groups, but the levels of anti-Hsp-antibodies decreased in cases only. A reduction in anthropometric and lipid profile in cases were sustained in the second period, however, only changes in lipid profile were observed in the control group. Anti-Hsp-antibodies and hs-CRP levels continued to be reduced in cases but in controls only the reduction in hs-CRP remained. Changes in anthropometric parameters, lipid profile, and anti-Hsp-antibodies were more evident in cases. Body acupuncture in combination with diet restriction was effective in enhancing weight loss and improving dyslipidemia.

Validity of anthropometric estimations of body composition in high school wrestlers.  

PubMed

The purpose of this study was to determine the validity of 23 anthropometric equations for estimating body composition and minimal wrestling weight in high school wrestlers. A total of 409 high school wrestlers (M age +/- SD = 16.42 +/- 1.03 yrs) volunteered for this study. Twenty-three anthropometric measures including eight skinfolds, nine circumferences, and six diameters were obtained from each subject. The mean body density, determined from underwater weighing, was 1.0748 +/- 0.0100 g.cm-3. The crossvalidation analyses indicated that the quadratic skinfold equation of Lohman resulted in the most accurate estimation of body density. The total error, constant error, standard error of estimate, and r for this equation were 0.0077 g.cm-3, -0.0003 g.cm-3, 0.0076 g.cm-3 and .65, respectively. Furthermore, the results of this investigation indicated that the minimal wrestling weight equations of Tcheng and Tipton resulted in total error values (5.54 to 6.06 kg) which were too large to be of practical use for high school wrestlers.

Anthropometric Characteristics and Undernutrition Among Older Persons in a Rural Area of Northern India.  

PubMed

This community-based cross-sectional study was conducted to assess anthropometric characteristics and estimate the prevalence of undernutrition among older persons in rural Ballabgarh, Haryana, India. A total of 948 participants aged 60 years and above were examined. Their weight, arm span, mid-upper-arm circumference, triceps skinfold thickness, and calf circumference were measured using standard techniques. The prevalence of undernutrition was estimated to be 53.7% (95% confidence interval [CI] = 50.5-56.9). Logistic regression analysis was done to identify factors independently associated with undernutrition. In the assessment of anthropometric characteristics, the strongest correlation was observed between body mass index and mid-upper-arm circumference (r = 0.88; P < .0001). Receiver operating characteristic analysis showed that mid-upper-arm circumference has a higher ability (area under curve = 0.93; 95% CI = 0.91-0.96) of detecting undernutrition among older persons than triceps skinfold thickness and calf circumference. The high prevalence of undernutrition among older persons in rural India warrants major public health interventions. PMID:23728770

Anthropometric indexes outperform bioelectrical impedance analysis-derived estimates of body composition in identification of metabolic abnormalities in morbid obesity.  

PubMed

BACKGROUND: The validity of anthropometric indexes in ascertaining the body composition (BC) in morbidly obese (MO) subjects has been questioned. Our objective was to evaluate, in MO subjects, whether bioelectrical impedance analysis (BIA) of BC is more closely associated with the metabolic syndrome (MS) and insulin resistance (IR) than are classic anthropometric measurements. The setting was a university hospital. METHODS: The association between anthropometric (body mass index, waist circumference [WC]) and BIA (total fat mass [FM] [percentage of FM], truncal FM, android FM) estimates of BC, MS, and IR was evaluated in 784 white MO subjects (212 men and 572 women). BIA estimates were calculated using equations specific for MO subjects developed by our own group and validated against dual energy x-ray absorptiometry. RESULTS: The prevalence of the MS and IR was 78.6% and 88.6%, respectively. The body mass index was greater in women with the MS (P <.001) or IR (P <.001), and the WC was larger in subjects of both genders with the MS or IR (P <.001). Moreover, the WC correlated significantly with all the MS components (P <.05). In contrast, the percentage of FM, truncal FM, and android FM were significantly associated with the MS only in women. Stepwise logistic regression analysis demonstrated the WC as the only significant predictor of the MS or IR (both P <.001). Furthermore, receiver operating curve analysis showed WC was the most accurate BC parameter for the identification of subjects with the MS (area under the curve, WC = .681, P <.001) or IR (area under the curve, WC = .753, P <.001). CONCLUSION: In MO subjects, the BIA-derived indexes of total and central adiposity were not better predictors of the MS or IR than were traditional anthropometric measurements. PMID:22867555

Anthropometric estimations of percent body fat in NCAA Division I female athletes: a 4-compartment model validation.  

PubMed

Anthropometric equations, based on 2-compartment models, have been routinely used to estimate body composition in female college athletes; however, these equations are not without error. In an attempt to decrease the error associated with anthropometric equations, updated equations were developed using multiple-compartment models, although the validity of these equations has not yet been established. The purpose of the current investigation was to determine the validity of the updated anthropometric equations and compare them with previously validated generalized equations for estimating percent fat (%fat) in female athletes. Twenty-nine white female NCAA Division I athletes (20 +/- 1 years) volunteered to have their %fat estimated using anthropometric measurements. Skinfold equations included generalized and updated equations and a height and weight-based equation. %fat values were compared with a criterion 4-compartment model. All equations produced low total error (TE) (< or =3.38%fat) and SEE values (< or =2.97%fat) and high r values (r > or = 0.78). The 2 updated skinfold equations produced the highest constant error (CE) values, but the tightest limits of agreement (< or = -1.58 +/- 4.86%fat; CE +/- 2SD) compared with the 3 generalized Jackson et al. equations (< or =0.92 +/- 5.34%fat), whereas the limits of agreement for the height and weight-based equation (+/- 6.00%fat) were the widest. Compared with the updated skinfold equations, the generalized Jackson et al. skinfold equations produced nearly identical TE values. Results suggest that the updated skinfold equations are valid but not superior to the generalized Jackson et al. equations, and the height and weight-based equation of Fornetti et al. is not recommended due to the large individual error in this population. Additionally, more than 3 skinfold sites did not improve %fat values. Therefore, the Jackson et al. sum of 3 skinfold equation is the suggested skinfold equation in the white female NCAA Division I athletes. PMID:19528870

Anthropometric, Gait and Strength Characteristics of Kenyan Distance Runners  

PubMed Central

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 ¼ 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. Key pointsThis is the first study in the literature to analyze the biomechanical characteristics of elite Kenyan distance runners, potentially providing insight into their success in distance running.Their slim limbs may positively contribute to performance by having a low moment of inertia and thus requiring less muscular effort in leg swing.Overall, short ground contact time was observed with the right leg shorter than the left leg. This 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 symmetry in strength between the left and right legs and possessed high hamstrings to quadriceps ratios compared to athletes in other sports.

[Hand hygiene: revolution and globalization].  

PubMed

Hand hygiene is the primary measure to prevent healthcare-associated infections and the spread of antimicrobial resistance. Low staff compliance remains a major problem. Successful promotion requires a multimodal strategy. The World Health Organization (WHO) proposes an approach including at least five components: system change, in particular the recourse to alcohol-based hand rubbing as the new standard of care, staff education using newly developed tools, monitoring and feedback of staff performance, reminders in the workplace, and promotion of an institutional safety climate. Patient participation in hand hygiene promotion is under testing. Early results of the strategy tested in a large number of healthcare settings in both limited- and high-resource countries are extremely encouraging. PMID:19492514

Hand Trauma Severity Scale (HTSS) was created on the basis of our study on 1199 patients who were treated because of the hand injuries in the Second Chair of Surgery Jagiellonian University in Krakow in years 1987-2000. (last examination in 2010, follow-up: 11 to 23 years, mean follow-up: 16 years). Hand Trauma Severity Scale (HTSS) has been created based on We looked at the range of injury, likely total length of treatment, final functional result and possible amount of posttraumatic disability. Created HTSS scale was compared to Hand Injury Severity Score (HISS) and their statistically significant correlation (p < 0,001) was found. We have also found statistically significant correlation between the severity evaluated with HTSS and the circumstances of traumas, their direct cause, necessity of hospitalization after primary reconstructive treatment and total length of treatment. Distant results of treatment such as resuming of previously performed work and permanent posttraumatic disability also correlated with the severity of hand injuries measured with scale described in this study.

The Multicomponent Anthropometric Model for Assessing Body Composition in a Male Pediatric Population: A Simultaneous Prediction of Fat Mass, Bone Mineral Content, and Lean Soft Tissue  

PubMed Central

The aim of this study was to propose and cross-validate an anthropometric model for the simultaneous estimation of fat mass (FM), bone mineral content (BMC), and lean soft tissue (LST) using DXA as the reference method. A total of 408 boys (8–18 years) were included in this sample. Whole-body FM, BMC, and LST were measured by DXA and considered as dependent variables. Independent variables included thirty-two anthropometrics measurements and maturity offset determined by the Mirwald equation. From a multivariate regression model (Ymn = x(r + 1)(r + 1)n?m + ?nm), a matrix analysis was performed resulting in a multicomponent anthropometric model. The cross-validation was executed through the sum of squares of residuals (PRESS) method. Five anthropometric variables predicted simultaneously FM, BMC, and LST. Cross-validation parameters indicated that the new model is accurate with high RPRESS2 values ranging from 0.94 to 0.98 and standard error of estimate ranging from 0.01 to 0.09. The newly proposed model represents an alternative to accurately assess the body composition in male pediatric ages.

Hands are us.  

PubMed

Hands play a distinctive role in establishing our identity, both as a tool-using species and as individuals with unique talents and self-awareness. The fit between hands and tools should be as natural (sensitive to the natural functioning of hands) as possible. Improper fit and use leads directly to injuries such as carpal-tunnel syndrome. It is also involved in injuries attributed to compensatory patterns and to unnecessary restrictions of career functioning. Injuries can be avoided or sometimes repaired by redesigning tools and work patterns rather than through surgical or medical means. The mass manufacture of one-size-fits-all tools violates existing individual differences in the hand and what is natural to it. The artist within us is repressed to the extent that we lose touch with the tools, media, and performance patterns of our work. This loss makes us less professional and places our hands at risk for damage. PMID:18303710

Patterns of hand preference and unintentional injuries among Indian attempted hand switchers and hand non-switchers.  

PubMed

This study examines the patterns of hand preference and unintentional injuries of attempted hand switchers and hand non-switchers. Data were collected from 3698 participants in Kharagpur, India, on measures of hand preference, hand switching, and unintentional injuries. The direction of left- or right-handedness was on the basis of hand used for the item "writing on paper" and the degree of handedness was based on the average score of remaining items in the handedness inventory. Results reveal that, among attempted hand-switchers, learned right-handers were not right-sided in hand continuum as the natural right-handers, but left-handers were left-sided as natural left-handers. With increasing age the learned right-handers become less right-sided and natural right-handers become more right-sided. Females (males) are found to be more right-handed than males (females) among learned right-handers (natural right-handers). On the direction of handedness, the learned right-handers have more than twice the risk of unintentional injuries than the natural right- and left-handers. On degree of handedness, the use of inconsistent left and both hands among natural left-handers, the use of inconsistent right and both hands among natural right-handers, and the use of weak right hand among learned right-handers increase their vulnerability to unintentional injuries. Any deviation from the genetic make-up in hand use elevates the risk of unintentional injuries, suggesting that one should not change the biological hand. PMID:23157575

Association among obesity-related anthropometric phenotypes: analyzing genetic and environmental contribution.  

PubMed

Obesity has become a public-health and policy problem in many parts of the world. Epidemiological and population studies in this field are usually based on different anthropometric measures; however, common genetic and environmental factors between these phenotypes have been scarcely studied. The objective of this article is to assess the strength of these factors on the covariation among a large set of obesity-related traits. The subject group consisted of 533 nuclear families living in the Greater Bilbao (Spain), and included 1,702 individuals aged 2-61 years. Detailed anthropometric measurements (stature, breadths, circumferences and skinfolds) were carried out in each subject. Bivariate quantitative genetic analyses were performed using a variance-components procedure implemented in the software SOLAR. The results revealed that the majority of these traits is affected by common genetic and environmental factors. All correlations were significantly different from 1 and varied from non-significant to very high (>0.90, P < 0.0001), with clearly lower pleiotropic effects among pairs including fat-distribution traits. Despite the strong common genetic effects detected among phenotypes determining the amount of body fat and mass, there is a residual genetic influence on the local fatness measures that cannot be explained exclusively by the genetic influence on overall fatness. Moreover, the observed relationships confirm a partially different genetic control of truncal and peripheral fat. In conclusion, our findings highlight the relevance of considering different types of traits in the prevention and treatment of obesity, as well as in the search for genes involved in its development.

Anthropometric and body composition characteristics during pregnancy: a study from West Bengal, India.  

PubMed

The present cross-sectional study was aimed at investigating changes in anthropometric, body composition and blood pressure characteristics during pregnancy. A total of 406 healthy, pregnant women aged between 16 and 33 years participated in the study. Pregnant women were recruited from the outpatient department of the two-referral hospital in Bolpur subdivision of Birbhum district, West Bengal, India. Anthropometric measures such as height, weight, three circumferences and skinfold thickness at four sites (biceps, triceps, subscapular and suprailaic) were obtained using standard techniques. Percentages of body fat (%BF), intra abdominal visceral fat (IVF), basal metabolic rate (BMR) and body mass index (BMI) were measured using an Omron body fat analyser. Two forenoon blood pressure measurements were also taken and averaged for analysis. Subjects were categorized into three trimester groups: Group I, n=30; Group II, n=163; and Group III, n=213. ANOVA with Scheffe's post-hoc test revealed that Group I had significantly lower mean than both Group II and Group III for systolic blood pressure and IVF, whereas Group I had significantly lower mean than Group III for BMI, BMR, %BF, diastolic blood pressure and skinfolds. The mean change in maternal weight from the first to the third trimester was merely 3 kg. Mean waist circumference varied from the first to the third trimester but not from the first to the second trimester. Furthermore, significantly increased systolic and diastolic blood pressure was observed across the trimesters. However, longitudinal studies involving interaction of body fat topography and pregnancy-induced hormones are required to further our understanding of gestation mechanism. PMID:22551972

Nutritional risk and anthropometric evaluation in pediatric liver transplantation  

PubMed Central

OBJECTIVE: To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. METHOD: 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. RESULTS: 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. CONCLUSION: 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.

The purpose of the present investigation was to evaluate body proportionality in 417 men and 642 women of the different age groups: juvenile, I and II periods of mature age, and elderly age, living in the city of Krasnoyarsk. Anthropometric studies were conducted with the determination of longitudinal and width dimensions of the body. The significant differences between the proportionality parameters were detected in men. Young men were tall, had narrow shoulders and pelvis, their trunk had rectangular shape. Hands were proportional to the body length, the torso and legs were elongated. Mature and aged men were of medium height, had wide pelvis and trapezoid-shaped trunk. Both torso and legs were proportional to to the body length. No statistically significant differences between the parameters, defining the body proportions, were found in the women of different age groups. The correlation coefficients were determined between the body length and the parameters characterizing longitudinal and transverse sizes of the body of the individuals examined. PMID:20593588

The hand is one of the most commonly injured locations in children. In the young child, the ignorance of dangers may explain this frequency. In the older child, hand trauma is usually secondary to recreational sports. Most hand injuries in children are treated nonoperatively because of high remodeling potential. Surgical treatments are mandatory in case of open or unstable fracture, displaced intraarticular fractures and displaced phalangeal neck fractures. In phalangeal neck fractures, percutaneous treatment should be preferred. Finger stiffness and non-union are uncommon and are usually in relation with skin or vascular involvement. In case of physis fracture, clinical and radiological follow-up should monitor any growth problems. PMID:23522978

The Left Hand Second to Fourth Digit Ratio (2D:4D) Does Not Discriminate World-Class Female Gymnasts from Age Matched Sedentary Girls  

PubMed Central

Introduction The second to fourth-digit-ratio (2D:4D), a putative marker of prenatal androgen action and a sexually dimorphic trait, has been suggested to be related with sports performance, although results are not univocal. If this relation exists, it is most likely to be detected by comparing extreme groups on the continuum of sports performance. Methods In this study the 2D:4D ratio of world-class elite female artistic gymnasts (n?=?129), competing at the 1987 Rotterdam World-Championships was compared to the 2D:4D ratio of sedentary age-matched sedentary girls (n?=?129), alongside with other anthropometric characteristics including other sexually dimorphic traits such as an androgyny index (Bayer & Bayley) and Heath-Carter somatotype components (endomorphy, mesomorphy, ectomorphy) using AN(C)OVA. 2D:4D was measured on X-rays of the left hand. Results Left hand 2D:4D digit ratio in world class elite female gymnasts (0.921±0.020) did not differ significantly from 2D:4D in age-matched sedentary girls (0.924±0.018), either with or without inclusion of potentially confounding covariates such as skeletal age, height, weight, somatotype components or androgyny index. Height (161.9±6.4 cm vs 155.4±6.6 cm p<0.01), weight (53.9±7.6 kg vs 46.2 6.3 kg p<0.01), BMI (20.51±2.41 kg/m2 vs 19.05±1.56 kg/m2), skeletal age (15.2±1.1 y vs 14.5±1.2 y p>0.01), somatotype components (4.0/3.0/2.9 vs 1.7/3.7/3.2 for endomorphy (p<0.01), mesomorphy (p<0.01) and ectomorphy (p<0.05) respectively) all differed significantly between sedentary girls and elite gymnasts. As expressed by the androgyny index, gymnasts have, on average, broader shoulders relative to their hips, compared to the reference sample. Correlations between the 2D:4D ratio and chronological age, skeletal age, and the anthropometric characteristics are low and not significant. Conclusion Although other anthropometric characteristics of sexual dimorphism were significantly different between the two samples, the present study cannot discriminate sedentary girls from world-class female gymnasts by means of the left hand 2D:4D ratio.

Genome-wide Association Study of Anthropometric Traits in Kor?ula Island, Croatia  

PubMed Central

Aim To identify genetic variants underlying six anthropometric traits: body height, body weight, body mass index, brachial circumference, waist circumference, and hip circumference, using a genome-wide association study. Methods The study was carried out in the isolated population of the island of Kor?ula, Croatia, with 898 adult examinees who participated in the larger DNA-based genetic epidemiological study in 2007. Anthropometric measurements followed standard internationally accepted procedures. Examinees were genotyped using HumanHap 370CNV chip by Illumina, with a genome-wide scan containing 316?730 single nucleotide polymorphisms (SNP). Results A total of 11 SNPs were associated with the investigated traits at the level of P?anthropometric traits makes CRIM1 and ITGA1 highly interesting for further replication and functional follow-up. Increased linkage disequilibrium between the used markers in an isolated population makes the formal significance threshold overly stringent, and changed allele frequencies in isolate population may contribute to identifying variants that would not be easily identified in large outbred populations.

Nutrition and education. IV. Clinical signs of malnutrition and its relationship with socioeconomic, anthropometric, dietetic and educational achievement parameters.  

PubMed

The objective of this study was to determine the prevalence of clinical signs of malnutrition, and to measure the interrelationship with socioeconomic, anthropometric, dietetic and educational achievement parameters. A random sample of 550 Chilean elementary and high school graduates (1:1), of both sexes (1:1), from public and private schools (1:1) and from high, medium and low socioeconomic status (SES) (1:1:1), was chosen in the Metropolitan Area of Santiago, Chile. SES was measured through the Graffar Modified Scale. Clinical signs of malnutrition were assessed according to Jelliffe. Nutritional status was determined by means of anthropometric measurements: percentages of weight/age (W/A), height/age (H/A) and weight for height (W/H) were compared with the WHO Tables; head circumference/age (HC/A) with the Tanner Tables, and branchial anthropometric parameters by applying the Frisancho norms. Standard procedures for the 24 hour dietary recall interviews were used to collect data, and adequacy of intake was assessed by the FAO/WHO pattern. Educational achievement (EA) was measured through the Achievement Evaluation Program, (AEP) and Academic Aptitude Test (AAT) in elementary and high school graduates, respectively. Results showed that apart from caries (87.5%), most prevalent clinical signs of malnutrition were dermatosis (13.4%), follicular hyperkeratosis type I (13.2%), nasolabial dyssebacea (7.9%), lustreless hair (7.7%), angular stomatitis (4.4%) and cheilosis (2.7%). The number of clinical signs of malnutrition was found inversely and significantly associated with SES, H/A, vitamin A and calcium intake, as well as with EA, besides registering a lower nutrient intake, specially for energy, riboflavin and niacin.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1308641

Anthropometric and nutritional assessment in Italian elderly subjects.  

PubMed

The aims of this anthropometric study on 486 non-institutionalized subjects aged 60 and over were to assess the body mass index (BMI), to evaluate possible sex and age-linked differences of BMI and to find whether there were any correlations with systolic and diastolic blood pressure. To this end, the subjects were divided into three age groups: A: 60-69 years, B: 70-79 years and C: > or =80 years old. The results showed a high prevalence (74%) of overweight or clearly obese subjects (BMI >25.1 for men and BMI > 23.9 for women) (70% male and 77% female). Both the BMI and diastolic blood pressure showed a decreasing trend in the three age groups and were significantly correlated in the total population (p < 0.001). A dietary investigation using a 24-hour recall method, repeated on three separate days, was carried out on a subsample of 90 subjects, selected at random from the total population. They underwent in-depth anthropometric assessment (BMI, four skinfolds, mid-arm, waist and hip circumferences, midarm muscle and fat areas, body fat percent). The trend of the anthropometric assessment reflected that of the total population. Total energy intake in both sexes did not significantly differ from the Italian RDA (Recommended Dietary Allowance). As regards the three macronutrients, no significant differences in protein and carbohydrate intakes were found between the sexes. However, in the females, fat intake was over the Italian DRA (30%) and below it in the males. Calcium intake was lower than the Italian RDA (1,000 mg/day) in most males (77%) and females (89%). However, iron and vitamin intakes were adequate in most subjects. As regards age-linked differences, there were non significant changes in the percentage of energy intake from proteins of the males whereas this decreased with age and was significantly different (p < 0.05) in the females. No significant differences were found in the percentage of energy intake from carbohydrates and fats. PMID:10995087

A study of correlation of hand and foot dimensions for personal identification in mass disasters.  

PubMed

The identification of isolated extremities is an issue of great significance in the investigation of the identity of victims of mass disasters and fatal assaults. In forensic investigations, the dimensions of the hand and foot have been used for determination of sex, age and stature of an individual. However, the data on correlation within and between hand and foot dimensions are very limited. The present research aims at analysing the anthropometrical relationships within and between hand and foot dimensions. The study was conducted on 240 Rajputs (120 males and 120 females) from North India. The results showed a significant correlation between and within the dimensions of hands and feet. Multiplication factors, linear and multiple regression models are derived to reconstruct the hand and foot even when a single dimension is available from the extremities. Besides medico-legal implications, the study may have significance in plastic and reconstructive surgery. PMID:20382487

Anthropometric studies on the Turkish population--a historical review.  

PubMed

A historical review of anthropometric studies conducted on Turkish children and adults is presented. In view of observed differences in growth status between children of different societies, the need for local reference standards and the methodology to be used for such studies have been stressed. The importance of local studies in reflecting the state of health and nutrition both in children and adults has also been mentioned. While a number of studies in children cited in this paper are designed to compare the growth of children from different socioeconomic levels, other studies aim to establish local reference data for Turkish children. While the historical studies in adults aim to define racial characteristics, the more recent studies aim to bring out nutritional characteristics with emphasis on increasing frequency of obesity.

Genome-wide association of anthropometric traits in African- and African-derived populations.  

PubMed

Genome-wide association (GWA) studies have identified common variants that are associated with a variety of traits and diseases, but most studies have been performed in European-derived populations. Here, we describe the first genome-wide analyses of imputed genotype and copy number variants (CNVs) for anthropometric measures in African-derived populations: 1188 Nigerians from Igbo-Ora and Ibadan, Nigeria, and 743 African-Americans from Maywood, IL. To improve the reach of our study, we used imputation to estimate genotypes at approximately 2.1 million single-nucleotide polymorphisms (SNPs) and also tested CNVs for association. No SNPs or common CNVs reached a genome-wide significance level for association with height or body mass index (BMI), and the best signals from a meta-analysis of the two cohorts did not replicate in approximately 3700 African-Americans and Jamaicans. However, several loci previously confirmed in European populations showed evidence of replication in our GWA panel of African-derived populations, including variants near IHH and DLEU7 for height and MC4R for BMI. Analysis of global burden of rare CNVs suggested that lean individuals possess greater total burden of CNVs, but this finding was not supported in an independent European population. Our results suggest that there are not multiple loci with strong effects on anthropometric traits in African-derived populations and that sample sizes comparable to those needed in European GWA studies will be required to identify replicable associations. Meta-analysis of this data set with additional studies in African-ancestry populations will be helpful to improve power to detect novel associations. PMID:20400458

Dependence of the Geriatric Depression on Nutritional Status and Anthropometric Indices in Elderly Population  

PubMed Central

Objective Malnutrition and depression are highly prevalent in the elderly and can lead to unfavorable outcomes. The aims of the current study were to determine the association between malnutrition and depression and also to find any correlation of depression with some anthropometric indices in free living elderly. Method In this cross-sectional study, 337 elderly subjects (193 females) were selected using cluster sampling. Depressive symptoms and nutritional status were determined by the Geriatric Depression Scale (GDS) and the Mini-Nutritional Assessment (MNA) scores questionnaires, respectively. Anthropometric indices were measured all in standard situations. Chi squared test and t-test were used when necessary. Pearson correlation coefficients were calculated for linear relations between variables. Results Of all the total subjects, 43.62% were depressed; and of whom, 48.01% were malnourished or at risk of malnutrition. GDS had a significant negative dependence with the MNA for the entire sample (r=-0.58, p <0.0001). However, there was no significant correlation between age and GDS or MNA scores. Moreover, the mean GDS scores differed significantly between men and women (p <0.05), and women were more depressed than men (27.9% vs. 15%, respectively). The elderly subjects living in urban areas were more depressed than those living in rural areas (39.46% vs. 3.85% respectively). Conclusion The results of the present study revealed a high prevalence of depression and malnutrition among old subjects. Moreover, depression was associated with worsening of nutritional status. The mechanism of this association needs further study.

Anthropometric predictors of geometric indices of hip bone strength in a group of Lebanese postmenopausal women.  

PubMed

The effects of anthropometric characteristics on hip bone strength in postmenopausal women are not completely elucidated. The aim of this study was to investigate the influence of anthropometric characteristics on geometric indices of hip bone strength using the hip structure analysis (HSA) program in a group of Lebanese postmenopausal women. This study included 109 postmenopausal women (aged 64--84yr). Age and years since menopause were recorded. Body composition and bone mineral density were assessed by dual-energy X-ray absorptiometry (DXA). To evaluate hip bone strength, DXA scans were analyzed at the femoral neck (FN), the intertrochanteric (IT), and the femoral shaft (FS) by the HSA program. Cross-sectional area (CSA), an index of axial compression strength, section modulus (Z), an index of bending strength, and buckling ratio (BR), an estimate of cortical stability in buckling, were measured from bone mass profiles. Using univariate analysis, weight, height, body mass index (BMI), lean mass, and fat mass were positively correlated to CSA and Z of the FN, IT, and FS. Weight, BMI, fat mass, and fat mass percentage were negatively correlated to BR of the FN, IT, and FS. Multiple linear regression analysis showed that lean mass was a stronger determinant of FN CSA, FN Z, IT Z, and FS Z than fat mass, whereas fat mass was a stronger determinant of IT CSA, FS CSA, IT BR, and FS BR than lean mass. This study suggests that, in postmenopausal women, fat mass is a strong predictor of hip axial compression strength and cortical stability in buckling, and lean mass is a strong predictor of hip bending strength.

Interrelationships between strength, anthropometrics, and strongman performance in novice strongman athletes.  

PubMed

The sport of strongman is relatively new; hence, specific research investigating this sport is currently very limited. The purpose of this study was to determine the relationships between anthropometric dimensions and maximal isoinertial strength to strongman performance in novice strongman athletes. Twenty-three semiprofessional rugby union players with considerable resistance training and some strongman training experience (age 22.0 ± 2.4 years, weight 102.6 ± 10.8 kg, height 184.6 ± 6.5 cm) were assessed for anthropometry (height, body composition, and girth measurements), maximal isoinertial performance (bench press, squat, deadlift, and power clean), and strongman performance (tire flip, log clean, and press, truck pull, and farmer's walk). The magnitudes of the relationships were determined using Pearson correlation coefficients, and interpreted qualitatively according to Hopkins (90% confidence limits ?±0.37). The highest relationship observed was between system force (body mass + squat 1-repetition maximum) and overall strongman performance (r = 0.87). Clear moderate to very large relationships existed between performance in all strongman events and the squat (r = 0.61-0.85), indicating the importance of maximal squat strength for strongman competitors. Flexed arm girth and calf girth were the strongest anthropometric correlates of overall strongman performance (r = 0.79 and 0.70, respectively). The results of this study suggest that body structure and common gymnasium-based exercise strength are meaningfully related to strongman performance in novice strongman athletes. Future research should investigate these relationships using more experienced strongman athletes and determine the relationships between changes in anthropometry, isoinertial strength, and strongman performance to determine the role of anthropometry and isoinertial strength in the sport of strongman.

Mechanical hands illustrated  

SciTech Connect

In the field of robotics, considerable effort is devoted to the development of effective multiple prehension manipulator systems. Most of these efforts have been directed toward attempts to duplicate certain functions of the human hand for industrial and medical applications. The human hand is an intricate and complex system capable of a multitude of sensory and actuation functions. It has approximately 20 degrees of freedom controlled by a large number of muscles compared to only 7 degrees of freedom for the arm and wrist. Since the primary function of a mechanical hand is to grasp or pinch different objects, not all the degrees of freedom are necessary for every robot or prosthetic device. Most practical tasks for manipulators have their special requirements and constraints which influence the design of their end effector. Consequently various hand configurations have to be designed to effectively provide the required functions for a particular application without additional complexity. The control of these functions is accomplished by suitable actuators. Miniature touch and pressure sensors which can be as small as 3 mm in size are used to control the grip. This book discusses the knowledge base in the field of robotics. It provides an excellent compilation of photographs, scaled drawings, and source material for a wide variety of mechanical hands for the user to choose from.

Comparison of the validity of anthropometric and bioelectric impedance equations to assess body composition in adolescent girls.  

PubMed

OBJECTIVE: The purpose of this study was to examine the validity of two anthropometric and four bioelectric impedance (BIA) equations to estimate body composition from dual-energy x-ray absorptiometry (DXA) in adolescent girls of various ethnicities. The rationale for this study was to develop a prediction equation for percent body fat in a multi-ethnic, representative sample of sixth to eighth grade girls. DESIGN: One-hundred and sixty-six girls (51 African-American, 45 non-Black Hispanic, 55 non-Hispanic Caucasian, 15 multi-ethnic) participated. Estimates of percent fat and fat-free mass (FFM) from six published BIA and anthropometric equations and the equation developed from this study were compared to body composition determined from DXA. An RJL Systems analyzer was used to measure BIA. Anthropometry included body weight, height, and triceps and calf skinfolds. RESULTS: Average (± SD) age, size and body composition was as follows: age, 12.1±1.2 yrs, body mass 52.7±15.9 kg, height, 154.6±8.1 cm; DXA percent fat, 27.9±10.4; fat mass (FM), 15.6±10.2 kg; and fat free mass (FFM) 35.7±6.8 kg. No ethnic differences were found in the relationships between estimated and DXA measured body composition, with the exception of the skinfold equation. The six equations explained on average 82% of the variance in percent fat, 94% of the variance in fat mass, and 88% in fat free mass. Bland-Altman analysis indicated that none of the equations performed satisfactorily in our sample. CONCLUSIONS: The BIA and anthropometric equations were significantly related to DXA body composition parameters, however none met the criteria for cross-validation. PMID:18163160

Inspections of hand washing supplies and hand sanitizer in public schools.  

PubMed

Hand washing and hand antisepsis are proven infection control measures in the school setting, yet barriers such as lack of soap, paper towels, and hand sanitizer can hinder compliance. This pilot study measured the prevalence of hand cleaning supplies in public schools. Ten school districts (93 schools) participated in school nurse inspections. In November 2008, 90 schools (97%) reported their inspection results. Among 697 total bathrooms, 88.8% had soap and 91.7% had paper towels or hand dryers. Hand sanitizer was reported in 1.2% of bathrooms and 15.2% of cafeterias. No difference was observed between boys' and girls' bathrooms, or primary and secondary schools, in the prevalence of soap or paper towels/hand dryers. Hand washing supplies were generally available in public school bathrooms. Alcohol-based hand sanitizer in school bathrooms was reported occasionally and should be discouraged. Hand sanitizer in a supervised setting, the school cafeteria, was not often reported and should be promoted. PMID:20457946

Diabetic hand infections.  

PubMed

Compared with the limited experience reported in the literature to date, analysis of the authors' clinical series of hand infections demonstrates that more than one third of the patients are diabetic. This can be attributed to the population of African-Americans in Washington, DC, the high incidence of diabetes in this particular race, and the inherent susceptibility of diabetics to develop an infection of the hand. The most severe infections occur in insulin-dependent diabetic patients or those with chronic renal failure because of protein depletion, poor wound healing, neuropathy, and ischemia. Although a similar spectrum of infections is encountered in diabetic and nondiabetic patients, some characteristic presentations are somewhat unique to the diabetic population. Gram-negative and mixed organism infections are particularly common in diabetic patients. Despite the poor prognosis of diabetic hand infections in general and the unsatisfactory outcome in patients on renal dialysis, most diabetic patients successfully heal following early and appropriate intervention. Early diagnosis and aggressive and adequate surgical drainage and tissue excision or amputation (if indicated) are key principles. The authors have learned that the surgical incision must extend along the entire area of erythema and induration because the infection often is more extensive than suspected both before and during the initial surgery. Observation, local wound care, and the administration of antibiotic agents are not acceptable substitutes for surgical decompression in the diabetic patient with a hand infection. In the subgroup of diabetic patients most prone to develop hand infections (i.e., associated renal dialysis), the surgeon must recognize that ongoing tissue loss is commonplace, repeat wound debridements are required, and an eventual amputation is highly likely.

[Dietary patterns and selected anthropometric parameters of nutritional status of men between 20 and 60 years old from Krakow population].  

PubMed

The purpose of research was to analyze relations between dietary patterns and anthropometric parameters of nutritional status among working men, living in big city population. Tests involved a group of 1451 men between 20 and 60 years old, employed in Steelworks of T. Sendzimir (HTS) in Krakow, Poland. Comparison was done for average values of anthropometric indexes of men in sections of 10 years of age and two categories of persons--of the least (I section) and of the most reasonable nutrition choices (II section). Research pointed out the relation between the quality measurement of nutrition method and some of anthropometric indexes of nutritional status. In selected sections of the least and of the most reasonable nutrition choices there were no differences between average values of 4 skinfolds, waist and arm perimeter, Waist to Hip Ratio distribution index (WHR) and average values of Fat Free Mass (FFM). Unawares characteristically higher average values of BMI were found at men of 20-30 years old (23.91 vs. 25.45 kg/m2, p < 0.05) and 50-60 years old (26.42 vs. 28.00 kg/m2, p = 0.01) declaring more rational nutrition behaviors. Similar regularity was ascertained for percentage of body fat tissue (%BF); higher nutrition habit mark is accompanied with higher average value of %BF at 20-30 years old (15.17 vs. 18.24%, p < 0.01) and 50-60 years old (22.76 vs. 25.01, p < 0.05).

The purpose of this study was to determine the anthropometric profile and nutrient intakes of 86 adults with cerebral palsy. When compared with growth standards for healthy individuals, the mean body fat percentages and body mass indexes of both men and women with CP were within the normal range. However, 40% of the sample had heights below the 5th percentile for their age and gender, indicating permanent growth stunting. In general, the diets of these individuals were similar to the typical American diet. Both men and women had low nutrient adequacy ratios (NARs) for calcium (0.86 and 0.76, respectively); the women also had low NARs for iron (0.69) and niacin (0.86). Although nutrients obtained from supplements were not included in the NAR score, 26% of the men and 50% of the women reported using nutritional supplements. Fifty-five percent of the sample reported feeding problems. Multivariate analysis illustrated that individuals who participated in regular exercise programs had significantly higher mean adequacy ratios and lower body fat percentages than those who did not exercise regularly.

Combination hand rejuvenation procedures.  

PubMed

Although the hands age at the same rate as the face, the aging process differs and requires a combination treatment approach for optimal rejuvenation. Photoaging causes epidermal changes such as lentigines, actinic keratoses, fine wrinkles, and crepe-like textural change. Thinning of the dermis and subcutaneous fat occurs as a result of both ultraviolet light exposure and intrinsic aging. This process can lead to a skeletal appearance of the hands, with prominent veins and bulging tendons. The combination approach addresses all of these issues, employing lasers, intense pulsed light devices, fractional devices, fillers, peels, vein sclerotherapy, and an effective at-home skin care program as indicated for individual needs and concerns.

Validation of ADEOS-II/GLI ocean-color atmospheric correction based on ship-board hand-held spectroradiometer measurements  

NASA Astrophysics Data System (ADS)

The paper compares GLI-derived estimates obtained under "version 2" GLI standard atmospheric correction algorithm with in situ measured data collected by SIMBADA handheld above-water radiometer, intending the evaluating the performance of the algorithm which includes empirical absorptive aerosol correction as well as sun glint correction. Over 395 match-up data, average estimation error (difference between GLI-derived and SIMBADA-measured data) in normalized water-leaving radiance (nLW) is 0.3 ?W/cm2/nm/sr in 412 and in 443 nm bands, showing improvement from version 1 GLI atmospheric correction by 10-30 %, whereas estimation bias is reduced significantly. The GLI-derived aerosol optical thickness (AOT) in 865 nm band show 0.1 RMS error against SIMBADA measurement on average, whereas Angstrom exponent estimate shows significant bias, suggesting potential calibration offset among GLI near-infrared bands. Despite relatively large scattering in nLW match-up analysis, comparison between GLI chlorophyll a concentration estimates and SIMBADA-derived estimation show highly correlated and consistent relation. This will suggest that fluctuations in nLW estimate are systematic over GLI visible channels although the nature of the variability requires further investigation.

Pediatric mutilating hand injuries.  

PubMed

Mutilating hand injuries in children are a devastating problem. With aggressive efforts at replantation and revascularization, methodic debridement, timely soft tissue coverage, and early mobilization, however, the results in these unfortunate children can be quite rewarding. The child often does well with the functional aspect of recovery and rehabilitation but will probably hide his or her deformed hand from friends and family. These children generally become more shy and reserved. The parents are the key to rehabilitation. A good relationship between the parent, the physician, and the hand therapist is essential for the best result. Interestingly, the parents who are the most demanding on the staff during the initial emergency period are often the most appreciative parents and their children often achieve the best result. Conscientious parents are the best advocates for their children. Obviously, the prevention of these devastating injuries is much preferable to extraordinary heroic reconstruction. Unfortunately, some injuries are inevitable. It is nearly impossible to create an absolutely hazard-free environment for children. Potential injuries can be avoided, however, simply by keeping hazardous machines and equipment out of the reach of the child and by keeping children out of the potentially dangerous workplace.

[Rehabilitation of the rheumatoid hand].  

PubMed

Treatment of patients suffering from rheumatoid arthritis is complicated and it consists mainly of applying general measures, medical therapy, physical therapy and rehabilitation, and, if necessary, surgical - orthopedic measures. The treatment is conducted as team work and it lasts for years. The chronic and evolutionary character of the disease requires a rather dynamic effort against the onset of joint deformation as well as the constant follow up of the evolution of the disease, and the local condition of the joints. Within the examined group of a hundred patients with classical and definitive rheumatoid arthritis, formed deformations of hand joints were registered in 72% of patients by means of clinical examination. Preventive measures against joint deformation make an integral part of rheumatoid arthritis patient treatment. Their application starts from the moment when the diagnosis is made and lasts as long as the disease does. PMID:2233556

Development and validation of anthropometric prediction equations for estimation of lean body mass and appendicular lean soft tissue in Indian men and women  

PubMed Central

Lean body mass (LBM) and muscle mass remain difficult to quantify in large epidemiological studies due to the unavailability of inexpensive methods. We therefore developed anthropometric prediction equations to estimate the LBM and appendicular lean soft tissue (ALST) using dual-energy X-ray absorptiometry (DXA) as a reference method. Healthy volunteers (n = 2,220; 36% women; age 18-79 yr), representing a wide range of body mass index (14–44 kg/m2), participated in this study. Their LBM, including ALST, was assessed by DXA along with anthropometric measurements. The sample was divided into prediction (60%) and validation (40%) sets. In the prediction set, a number of prediction models were constructed using DXA-measured LBM and ALST estimates as dependent variables and a combination of anthropometric indices as independent variables. These equations were cross-validated in the validation set. Simple equations using age, height, and weight explained >90% variation in the LBM and ALST in both men and women. Additional variables (hip and limb circumferences and sum of skinfold thicknesses) increased the explained variation by 5–8% in the fully adjusted models predicting LBM and ALST. More complex equations using all of the above anthropometric variables could predict the DXA-measured LBM and ALST accurately, as indicated by low standard error of the estimate (LBM: 1.47 kg and 1.63 kg for men and women, respectively), as well as good agreement by Bland-Altman analyses (Bland JM, Altman D. Lancet 1: 307–310, 1986). These equations could be a valuable tool in large epidemiological studies assessing these body compartments in Indians and other population groups with similar body composition.

[Anthropometric indicators and psychodynamics in 20-54 year old ethnic Georgian men].  

PubMed

Aim of our research is establishing interrelation of anthropometric and psychodynamic indicators of ethnic Georgian men with normal physical development. Totally 125 men from 20 to 54 years old were observed. The were divided into 7 age groups. The anthropometric data were processed by mathematical statistics methods. For the research of character and temperament a questionnaire by Aizenk and scales of temperament by Sheldon were used. The types of mood were determined by D. Uznadze method. For determination of intellect the schemes and tests approved in England and USA were used. It was found that among ethnic Georgian men phlegmatic and sanguine persons prevail; the interconnection between of anthropometric data and temperament are 0.4-0.5. Correlation between of anthropometric data and forms of character (introversion) increases by 0.4-0.54; interrelation between the forms of intellect (mathematical, verbal) and of anthropometric data grow by 0.4-0.6; with the age interconnection between the types of mood and anthropometric data decreases by 0.1-0.2. Thus, it was established that ethnic Georgian men of normal physical development from 20 to 54 years old are mainly dolichomorphic, of sanguine temperament, extravert, they have average verbal (logical) intellect, by type of mood they are plastic-dynamic, constant-stable, with average excitement, which means they are harmonious constitutional types.

The statistics of natural hand movements  

PubMed Central

Humans constantly use their hands to interact with the environment and they engage spontaneously in a wide variety of manual activities during everyday life. In contrast, laboratory-based studies of hand function have used a limited range of predefined tasks. The natural movements made by the hand during everyday life have thus received little attention. Here, we developed a portable recording device that can be worn by subjects to track movements of their right hand as they go about their daily routine outside of a laboratory setting. We analyse the kinematic data using various statistical methods. Principal component analysis of the joint angular velocities showed that the first two components were highly conserved across subjects, explained 60% of the variance and were qualitatively similar to those reported in previous studies of reach-to-grasp movements. To examine the independence of the digits, we developed a measure based on the degree to which the movements of each digit could be linearly predicted from the movements of the other four digits. Our independence measure was highly correlated with results from previous studies of the hand, including the estimated size of the digit representations in primary motor cortex and other laboratory measures of digit individuation. Specifically, the thumb was found to be the most independent of the digits and the index finger was the most independent of the fingers. These results support and extend laboratory-based studies of the human hand.

Anthropometric standardisation and quality control protocols for the construction of new, international, fetal and newborn growth standards: the INTERGROWTH-21st Project.  

PubMed

The primary aim of the INTERGROWTH-21(st) Project is to construct new, prescriptive standards describing optimal fetal and preterm postnatal growth. The anthropometric measurements include the head circumference, recumbent length and weight of the infants, and the stature and weight of the parents. In such a large, international, multicentre project, it is critical that all study sites follow standardised protocols to ensure maximal validity of the growth and nutrition indicators used. This paper describes in detail the anthropometric training, standardisation and quality control procedures used to collect data for these new standards. The initial standardisation session was in Nairobi, Kenya, using newborns, which was followed by similar sessions in the eight participating study sites in Brazil, China, India, Italy, Kenya, Oman, UK and USA. The intraobserver and inter-observer technical error of measurement values for head circumference range from 0.3 to 0.4 cm, and for recumbent length from 0.3 to 0.5 cm. These standardisation protocols implemented at each study site worldwide ensure that the anthropometric data collected are of the highest quality to construct international growth standards.

A multiple parallel hand-held gas chromatograph (GC) system which includes several independent GCs. Each independent GC has its own injector, separation column, detector and oven and the GCs are mounted in a light weight hand-held assembly. Each GC operates independently and simultaneously. Because of different coatings in different separation columns, different retention times for the same gas will be measured. Thus, for a GC system with multiple parallel GCs, the system can measure, in a short period, different retention times and provide a cross-reference in the determination of the measured gas and to become a two-dimensional system for direct field use.

The hand-reversal illusion revisited  

PubMed Central

The hand-reversal illusion is a visuomotor illusion that is commonly seen in children's play. When participants attempt to lift a designated finger while their hands are cross-folded, they are likely to erroneously lift the matched finger of the other hand; however, such errors are rare when subjects close their eyes. Based on the fact that the illusion disappears without visual input, researchers previously concluded that the illusion depends upon visual and proprioceptive conflict (Van Riper, 1935). Here, we re-evaluated this visual-proprioceptive conflict hypothesis by obtaining reaction time measurements because, in the original study, subjects might have relied on a strategy of responding more slowly to minimize making errors. We found that the impairment due to cross-folding one's hand persisted in the absence of the visual input, as evidenced by delayed response times (RTs). Further, we found that such impairment occurred when the fingers of only one hand were tested, indicating that the impairment was not due to left-right confusions of the hands during tactile identification or response selection. Based on these results, we suggest that the illusion is not solely due to the conflict between visual and proprioceptive information. Instead, we propose that the unusual configuration itself that involves a reversal of the left and right hands in external space also contributes to the impaired motor response.

Effects of Ramadan Fasting on Biochemical and Anthropometric Parameters in Physically Active Men  

PubMed Central

Purpose The aim of this study was to assess the effects of Ramadan fasting on several biochemical and anthropometric parameters in physically active men by comparing fasters and nonfasters before, during, and after Ramadan. Methods Eighteen physically active men (10 fasters and 8 nonfasters) participated in this study. Subjects visited the laboratory for a total of four sessions on the following occasions: three days before Ramadan (Bef-R), the 15th day of Ramadan (Mid-R), the 29th day of Ramadan (End-R), and 21 days after Ramadan (Post-R). During each session, subjects underwent anthropometric measurements, completed a dietary questionnaire and provided a fasting blood sample. Results Body weight and body fat percentage decreased in fasters by 1.9% (P<0.001) and 6.2% (P=0.003), respectively, but increased in nonfasters by 2.2% (P<0.001) and 10.2% (P=0.001), respectively, from Bef-R to End-R. Fasters’ hematocrit and hemoglobin increased by 5.3% (P<0.001) and 6.3% (P=0.01), respectively, from Bef-R to End-R, while neither of these parameters changed in nonfasters. Fasters experienced an increase in the following parameters from Bef-R to End-R: urea (8.7%; P<0.001), creatinine (7.5%; P<0.001), uric acid (12.7%; P<0.001), serum sodium (1.9%; P<0.001), serum chloride (2.6%; P<0.001) and high-density lipoprotein cholesterol (27.3%; P<0.001). Of these parameters, only creatinine increased (4.4%; P=0.01) in nonfasters. Conclusion We conclude that Ramadan fasting lowers body weight and body fat percentage and can elevate high-density lipoprotein cholesterol in physically active men. However, practicing aerobic exercise during a hot and humid Ramadan month can induce a state of dehydration marked by an increase in some renal function markers and serum electrolytes.

Prevalence and determinants of one month hand pain and hand related disability in the elderly (Rotterdam study)  

PubMed Central

Objective: To study the prevalence of hand pain and hand disability in an open population, and the contribution of their potential determinants. Methods: Baseline data were used from 7983 participants in the Rotterdam study (a population based study in people aged ?55 years). A home interview was used to determine the presence of hand pain during the previous month, rheumatoid arthritis, osteoarthritis in any joint, diabetes, stroke, thyroid disease, neck/shoulder pain, gout, history of fracture in the past five years, and Parkinson's disease, as well as age, sex, and occupation. Hand disability was defined as the mean score of eight questions related to hand function. Body mass index was measured and hand x rays were taken. Results: The one month period prevalence of hand pain was 16.9%. The prevalence of hand disability was 13.6%. In univariate analysis for hand pain, rheumatoid arthritis had the highest explained variance (R2) and odds ratio. For hand disability, aging showed the highest explained variance and Parkinson's disease had the highest odds ratio. All determinants together showed an explained variance of 19.8% for hand pain and 25.2% for hand disability. In multivariate analysis, positive radiographic hand osteoarthritis was a poor explanation for hand pain (R2 = 0.5%) or hand disability (R2 = 0). Conclusions: The contribution of available potential determinants in this study was about 20% for hand pain and 25% for hand disability in an unselected population of elderly people. Thus a greater part of hand pain/hand disability remains unexplained.

The aim of the study was to evaluate the effect of GH on body weight, body composition and cardiovascular risk factors in android obese men. Forty non-diabetic subjects aged 20 to 50 years-old with android obesity (WHR > 1) were divided in two groups, on a prospective randomized double-blind basis to receive treatment with GH (0.050 U/kg/day) or placebo for three months. Bioimpedance analysis, DEXA, indirect calorimetry and cardiovascular risk factors were done at the beginning and at the end of the study. Anthropometric measurements were evaluated monthly. Body weight was reduced (3.5 +/- 2.9 kg), as well as BMI (1.2 +/- 1.0 kg/m2), WHR (0.04 +/- 0.01) and fat mass (2.4 +/- 1.0 kg), total cholesterol (4.0 +/- 3.3 mg/dL) and LDL-cholesterol (5.7 +/- 2.7 mg/dL) in GH-treated patients. Percentual changes were statistically different from placebo. Benefits and risks of long-term GH use in obese patients are still largely unknown. PMID:16628277

Cross-sectional changes in anthropometric variables among Wapishana and Patamona Amerindian adults.  

PubMed

Although anthropometric information on South American Indian populations has been collected for many years, remarkably little is known about age-related changes in their body size in adulthood. The lack of baseline information on the normal pattern of aging among Amerindian adults hinders investigations into the health consequences of the many economic, environmental and demographic changes that are currently occurring among South American Indian populations. This study presents data on the body size and shape of a convenience sample of 345 Patamona and 186 Wapishana Amerindian adults over 20 years of age living in the remote interior of Guyana. Analysis of the cross-sectional data demonstrated significant declines in stature, sitting height, and biacromial width with age, while there were no changes in subischial leg length or arm length across the age range of the study populations. In contrast, body weight and body mass index (BMI--a measure of body fatness) only declined in those over 50 years of age, after a period of increase. Significant differences in adult linear body dimensions were found between the two Amerindian populations that were proposed to be the result of known differences in childhood growth performance. However, the greater BMI of the Wapishana was shown to be associated with their significantly greater current wealth, thereby highlighting the presence of biological consequences of wealth inequalities even within these subsistence farming populations.

Dynamic and static orthoses can be prescribed for any part of the upper limb to assist function or provide resistance exercise. Orthoses can be valuable in planning surgery and assisting return of function postoperatively. The importance of training in prescription, manufacture, fitting and wearing of orthoses is stressed and careful discussion with the patient is vital. Thermoplastic materials have provided a new spectrum of designs. Spring wire attachments developed at Chessington (Wynn Parry et al, 1970), Odstock (Glanville, 1962) and The London Hospital (Ellis, 1981) have introduced further possibilities. Designs should be functional and must be acceptable to the patient. PMID:6398183

Biomimetic EMG-prosthesis-hand  

Microsoft Academic Search

The purpose of this study is to develop a myoelectric prosthetic hand that simulates fundamental dynamic properties of the neuromuscular control system of human hand. In particular, this prosthetic hand mimics the property that both muscle viscoelasticity and gain of the stretch reflex vary linearly with the activity of muscle. Those nonlinear properties of the neuromuscular control system were realized

Recognising a hand by grasp  

Microsoft Academic Search

The present study aimed to demonstrate that motor representations are used to recognise biological stimuli. In three experiments subjects were required to judge laterality of hands and forearms presented by pictures. The postures of the hands were those assumed when holding a small, medium and large sphere. In experiment 1, the sphere held in hand was presented, whereas in experiment

Survival of women with colon cancer in relation to pre-cancer anthropometric characteristics: the Iowa Women's Health Study  

PubMed Central

Background We hypothesized that pre-cancer anthropometric variables are associated with mortality among women who developed colon cancer in a prospective cohort, the IWHS. Methods Over 1986-2005, 1096 incident cases of colon cancer were identified (mean age at diagnosis was 73y). Anthropometric characteristics were self-measured before colon cancer diagnosis (in 1986). Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and colon-cancer mortality, adjusted for age at cancer diagnosis, stage, education, smoking status, and pack-years of smoking. Results During the follow-up of up to 20 years, 493 women died; 289 had colon cancer as the underlying cause. The HRs of all-cause death were increased for the highest versus lowest tertile for weight: HR=1.39 (95%CI, 1.10;1.76) (p-trend=0.005), waist-to-hip ratio (WHR): HR=1.36 (95%CI, 1.08;1.72) (p-trend=0.008), and waist: HR=1.45 (95%CI, 1.15;1.82) (p-trend=0.001). Compared to body mass-index (BMI) 18.5-24.9 kg/m2, HRs were increased for BMI ?30 kg/m2: HR=1.45 (95%CI, 1.14;1.85), and among the few women with BMI<18.5 kg/m2: HR=1.89 (95% CI, 1.01;3.53). Colon cancer mortality was positively associated with WHR and waist: HR=1.37 (95%CI, 1.02;1.85) (p-trend=0.04) and HR=1.34 (95%CI, 1.01;1.80) (p-trend=0.05), respectively, for the highest versus lowest tertile. Conclusion Greater pre-cancer anthropometric measures and BMI<18.5 kg/m2 predicted poorer survival among colon cancer patients. Higher abdominal adiposity measured by WHR and waist was associated with increased risk of colon cancer death. Impact If true, pre-diagnostic obesity may be a modifiable risk factor for death in colon cancer patients.
