Diabetes in urban African Americans. XII. Anthropometry for assessing municipal hospital outpatients recently diagnosed with type 2 diabetes.

OBJECTIVE: Abdominal obesity is associated with insulin resistance and cardiovascular risk factors, but there has been little information published to advance the use of abdominal anthropometry in the care of diabetic patients. RESEARCH METHODS AND PROCEDURES: A cross-sectional survey of municipal hospital outpatients recently diagnosed with type 2 diabetes (73 men and 142 women of whom 89% were African Americans). Age-adjusted linear regression was used to compare the supine sagittal abdominal diameter (SAD), supine waist circumference, four anthropometric ratios, and the body mass index (kg/m2) for their ability to predict serum fasting C-peptide and lipid levels. RESULTS: The best predictor of log-transformed C-peptide was SAD/height (p<0.0001 for men; p=0.0003 for women). SAD/thigh circumference was the best predictor of log-transformed triglycerides for men (p=0.002) and of total cholesterol/HDL cholesterol for women (p=0.043). The body mass index was less able to predict C-peptide, HDL cholesterol and total cholesterol/HDL cholesterol than was SAD/height or SAD/thigh circumference or waist circumference/height. DISCUSSION: Anthropometric indices of abdominal obesity appear to be correlated with insulin production and lipid risk factors among municipal-hospital, type 2 diabetic patients much as they are in other studied populations. Since anthropometric data are inexpensively obtained and immediately available to the practitioner, their utility for preliminary clinical assessment deserves to be tested in prospective outcome studies.

The area between curves (ABC)--measure in nutritional anthropometry.

This paper considers a statistic--recently suggested by Mora--for the deviation of a sample distribution from a reference distribution which typically arises in anthropometry when using the nutritional indicators height/age, weight/age or weight/height. The statistic measures the area between curves (ABC) and stands for the mass of the sample distribution which is not covered by the reference distribution. The paper provides a statistical framework for the ABC and includes some minor corrections of Mora's original paper. For the normal distribution situation with common or different variances, formulae are derived which include a partition of ABC into parts corresponding to malnourished and well-nourished groups. However, the main result is a non-parametric generalization of the ABC, motivated by the fact that the nutritional indicators often have skewed distributions with heavier left tails. Non-parametric statistical inference is provided by linking the ABC to the Kolmogorov-Smirnov statistic.

Relationships between personality disorders and anthropometry, hormones and metabolism in women.

This study sought to examine the potential influence of personality disorders (PD) on anthropometry, hormones and metabolism in women. In a population sample of women born in 1956 (no.=270), estimates of PD:s by Structured Clinical Interview for DSM-III-R, Axis II, were correlated with anthropometric, endocrine, and metabolic factors. The PD:s were grouped into three thematic clusters: cluster A (characterized by oddness or eccentricity), cluster B (characterized by self-centeredness, emotionality, and erratic behavior) and cluster C (characterized by anxiety and fear). Subjects with cluster A PD:s had significantly increased body mass index (BMI, kg/m2) and abdominal sagittal diameter (cm) as well as lower salivary cortisol after dexamethasone (DEX) compared to controls. Subjects with cluster B also had a significantly higher abdominal sagittal diameter and significantly lower salivary cortisol levels after DEX than controls. In addition, subjects with cluster B PD:s had decreased levels of ACTH, and significantly higher concentrations of lactate and triglycerides, while high-density lipoprotein (HDL) cholesterol was significantly lower compared to controls. A significantly higher waist/hip ratio was seen among subjects with cluster C PD:s. In addition, these subjects had higher levels of insulin, glucose, lactate, triglycerides, total cholesterol and low-density lipoprotein (LDL) cholesterol than controls. Moreover, IGF-I and HDL cholesterol were significantly decreased in the former group. These results suggest that PD:s are involved in the development of obesity and abdominal fat accumulation in women, with different endocrine and metabolic profiles depending on the type of PD.

Shall the anthropometry of physique cast new light on the diagnoses and treatment of eating disorders?

Body weight is crucial to eating disorders. Beyond gender, age, and height it is determined by anthropometric features of physique, i. e. somatotypes. We investigated their impact on the anthropometric and metabolic assessment of nutritional status, psychometrics, and other clinical aspects of eating disorders. In 133 eating disordered girls (ICD-10 & DSM-IV criteria) of well-recorded catamneses, various somatometric measures (n = 133), serum leptin (n = 30), plasma tryptophan (n = 108), and psychometric scales (n = 119; EDI-64 & EAT-40) were examined, preferably on repeated occasions of their treatment and in comparison to 41 healthy controls. Somatotyping was performed by gender- and age-specific quintiles of Strömgren's Metrik Index (MI) derived from 6995 volunteers constituting the anthropometric reference.Somatotypes represent a significant factor for assessing nutritional status. Exhibiting higher EDI-64 bulimia ratings at admission, more prevalent self-induced vomiting and purgative substance abuse as well as prolonged refractory illnesses with more previous inpatient treatment trials but later admissions, heavier somatotypes were significantly underrepresented in our total clinical sample but more prevalent among bulimic eating disorders (p < 0.05). Neglecting the anthropometry of physique biases against the detection and treatment of eating disorders in heavier somatotypes at weights below general average. Henceforth, this shall be avoided by somatotyping according to frame indices.

Representation of a human head with bi-cubic B-splines technique based on the laser scanning technique in 3D surface anthropometry.

Three-dimensional (3D) anthropometry based on the laser scanning technique not only provides one-dimensional measurements calculated in accordance with the landmarks which are pre-located on the human body surface manually, but also the 3D shape information between the landmarks. This new technique used in recent ergonomic research has brought new challenges to resolving the application problem that was generally avoided by anthropometric experts in their researches. The current research problem is concentrating on how to shift and develop one-dimensional measurements (1D landmarks) into three-dimensional measurements (3D land-surfaces). The main purpose of this paper is to test whether the function of B-splines can be used to fit 3D scanned human heads, and to for further study to develop a computer aided ergonomic design tool (CAED). The result shows that B-splines surfaces can effectively reconstruct 3D human heads based on the laser scanning technique.

Trunk anthropometry of Hong Kong Chinese infants.

BACKGROUND: Disturbed growth of the trunk may result in abnormal sternocostal relationship and a variety of pectus deformities. AIMS: The purposes of this study were to establish norms of trunk anthropometry for dysmorphology identification in the newborns and to evaluate chest circumference as a predictor for low birth weight for outborn infants where weighing scales were unavailable. STUDY DESIGN AND SUBJECTS: A total of 10,339 Chinese infants (5478 males, 4861 females) with gestation 24-42 weeks from 12 hospitals were included. The anthropometric measurements analyzed included chest circumference, inter-nipple distance, sternal length and abdominal circumference. OUTCOME MEASURES: The LMS method using maximum penalized likelihood was used to perform model fitting of the anthropometric centiles for these physical parameters. RESULTS: References tables of the four physical parameters for newborns were constructed. Chest circumference showed the highest correlation with birth weight (male: r = 0.866, female: r = 0.883). The cut-off points for chest circumference of 295 (male) and 299 mm (female) were the best predictor for low birth weight. There were also racial differences in these parameters. When compared with French infants, Chinese newborns had smaller chest circumference. CONCLUSION: These physical parameters provide useful references and aid dysmorphology diagnosis in newborns of ethnic Chinese origin.

An alternative method of anthropometry of anterior cruciate ligament through 3-D digital image reconstruction.

Accurate and flexible measurements of length, area, and volume are important in evaluation of the mechanical properties of soft tissue. Although a number of contact-based and non-contact techniques have been reported in the literature, due to a variety of reasons such as cost, complexity, and low accuracy, the research community has not adopted a standardized technique. In this paper, an alternative method of measuring the geometric parameters of cadaver anterior cruciate ligament (ACL) is presented. In this method, a 3-D scan of the ACL is constructed using a simple, commercially available, scanning system. The 3-D scan is then analyzed using the 3-D Doctor Software to extract important information regarding the length, cross-sectional area, and volume of the ACL. The accuracy and repeatability of measurements obtained by this method are acceptable and comparable to existing non-contact methods. The limitation of the method is that surface concavities cannot be detected. However, the non-contact optical method, described here, has inherent advantages over the existing methods: (1) it is inexpensive; (2) it allows the determination of area at any distance along the length of the tissue of interest; (3) all relevant information including minimum area is extracted from one single application of the method; (4) the volume can be calculated with a simple additional step of length measurement although, for accurate results, condylar blockage must be minimized by coring the ACL out. The entire process of scanning takes less than 30 min. This technique has the potential to become a standard method in anthropometry of soft tissue.

A laser-aligned method for anthropometry of hands.

We have developed a laser-aligned measuring device to facilitate the measurement of linear hand dimensions. Our objective has been to make a simple, clinically applicable device for anthropometry of the hands in patients with arthritis in order to gauge the progression of hand deformities. The system provides an alternative to the use of rules, tapes, photogrammetry and least-squares devices which have previously been applied to hand measurements. The system delivers results which are not significantly different from those measured with rules and callipers and has a similar level of accuracy. The use of laser pointers for alignment facilitates measurements which necessitate picking the highest point of the hand. The device is portable and simple to use in the clinic. We have used it to measure hand dimensions in normal subjects and patients with arthritis. However, the system could equally well be used to facilitate measurement of other objects with an irregular surface profile.

[Blood pressure, physical activity and anthropometry in adolescents].

The relationship of blood pressure with physical activity and anthropometry was studied in 295 adolescents (mean age, 15.3 years) who entered 1. "formación profesional" (a technological training) in 1990 in Puerto Real, a village of Cádiz, Spain. Systolic and diastolic (fifth-phase Korotkoff) blood pressure, and anthropometrics measurements (weight, height and triceps and subscapular skinfolds thickness) were measured with standardized techniques. Habitual and sports physical activity were assessed by a self-reported questionnaire. The results reported in this study suggest that systolic blood pressure is associated with habitual physical activity in girls, and that the systolic blood pressure is associated weakly with sports activity in girls and in boys. The stronger predictor of blood pressure was Quetelet Index (kg/m2).

Ultrasound bone measurement in children and adolescents. Correlation with nutrition, puberty, anthropometry, and physical activity.

Ultrasound bone measurement in healthy Croatian children and adolescents has been evaluated. Relationships between pubertal status, anthropometry, nutrition, and physical activity with ultrasound bone parameter were analyzed. A total number of 501 children and adolescents of both sexes participated in the study. There were 244 prepubertal children (120 boys and 122 girls) and 259 postpubertal adolescents (112 boys and 147 girls). Anthropometric measurements included height, weight, percent of fat tissue, and body mass index. Quantitative ultrasound measurements of the heel (nondominant side) were performed using "Sahara" sonometer and included speed of sound (SOS), broad-band ultrasound attenuation (BUA), and calculated bone stiffness (QUI). Dietary data were assessed using specially designed semiquantitative food frequency questionnaire calculations based on the daily intakes of calcium, carbohydrates, fats, and proteins. Quantitative ultrasound bone measurements (BUA, SOS, and QUI) were similar in prepubertal boys and girls. Adolescent boys had significantly higher BUA (P<.01) than girls. The percentage of children and adolescents who consumed more than 1,000 mg of calcium per day were 54.8% and 48.7%, respectively. Body weight and pubertal status and activity were significantly correlated with bone stiffness but not the calcium intake. In this study, bone stiffness in children and adolescents is determined by pubertal status and body weight, rather than by calcium intake.

Body composition measurement: a review of hydrodensitometry, anthropometry, and impedance methods.

Human body composition is an expression of genetic and nutritional factors. It can change as a consequence of exogenous influences such as training, disease, or diet and is therefore of particular interest to nutrition professionals. Two of the main methods of estimating body composition in this review (hydrodensitometry and anthropometry) have been in use for decades, but the third method (bioelectrical impedance) is more recent. The procedure, theoretical basis, assumptions, standard error of estimates, and comparisons with other techniques are presented for each of the three methods. References to general and specific populations are presented that illustrate regression equations for different ages, ethnic groups, and gender. The advantages and disadvantages of the three methods are reviewed with reference made to the alternative compartment models. Other methods (DEXA, infrared interactance) are briefly reviewed.

New instrument for orbital anthropometry.

A new instrument for orbital anthropometry is described. It consists of the base for a slit-lamp upon which the patient's head rests and rulers mounted on three independently movable axes. The z-axis probe is used to measure sagittal relationship between the corneal apices and points on the orbital perimeter. The instrument was tested against a sliding caliper and its accuracy was found to be within 0.2 mm or 2%. Intra- and inter-observer reliability were assessed by repeated measurements of two subjects by three observers. The intra-observer reliability was 0.99. Variations between observers was not significantly different for points orbitale inferius (oi), nasion (n), and orbitale superius (os), however, there was a statistically significant difference for measurement of orbitale laterale (ol). The correlation between anthropometric readings for lateral orbital wall to apex corneal (ol-ac) and CT scans for the same landmarks was assessed. Analysis of variance showed no difference between the measurement methods. This anthropometer is convenient and accurate for measurement of the sagittal orbital-globe relationships. A disadvantage is that it cannot be used intraoperatively.

Comparison of anthropometry to DXA: a new prediction equation for men.

OBJECTIVE: This study compared three professionally recommended anthropometric body composition prediction equations for men to dual energy X-ray absorptiometry (DXA), and then developed an updated equation, DXA Criterion (DC) from DXA. DESIGN: Cross-sectional. SETTING: Exercise Physiology Lab. University of Missouri-Columbia, USA. SUBJECTS: A total of 160 men aged 18-62 y old. INTERVENTIONS: Percent body fat (%BF) by anthropometry was compared to DXA on the same day. RESULTS: Although %BF was significantly correlated (r=0.923-0.942) (P<0.01) with DXA for all three equations, each equation underestimated %BF (range=3.1-3.3%) (P<0.01) compared to DXA. The following DC equation for men was created: %BF=0.465+0.180(Sigma7SF)-0.0002406(Sigma7SF)(2)+0.06619(age); (Sigma7SF=sum of chest, midaxillary, triceps, subscapular, abdomen, suprailiac, thigh; age=years). The predicted residual sum of squares (PRESS) R(2) was high (0.90) and the PRESS standard error of estimates was excellent (2.2% at the mean) for the DC equation when applied to our sample of 160 men. CONCLUSIONS: The currently recommended anthropometric equations for men underestimate %BF compared to DXA. The DC equation yields a more accurate estimation of %BF in men aged 18-62 y old. The results from this study support the need for the current %BF standards and norms for men to be adjusted upward.

The association of body weight and anthropometry with mortality in elderly men: the Honolulu Heart Program.

OBJECTIVES: To assess the relationship of body weight and anthropometry to all-cause mortality in older men. DESIGN: A prospective cohort study of 3741 elderly Japanese-American men, enrolled in the Honolulu Heart Program. For this report, the follow-up began at baseline examinations (1991-1993), when the men were aged 71-93 y. MEASUREMENTS: Variables of interest were body mass index (BMI), waist-to-hip ratio (WHR), and the sum of the subscapular and triceps skinfold thickness. Possible confounders included age, education, physical activity index, smoking, alcohol consumption, systolic and diastolic blood pressure, cholesterol, glucose and insulin concentrations. RESULTS: After an average of 4.5 y of follow-up, 766 men (21%) had died. Higher BMI was associated with lower adjusted mortality risks (relative risk (RR)) highest vs lowest quintile-based category = 0.5, 95% confidence interval (CI): 0.4-0.6, P-trend < 0.001). Results were independent of WHR, and did not change after excluding current and former smokers or those who died within one year of follow-up. The relation between WHR and mortality appeared to be U-shaped, but after adjustment for BMI, a higher WHR steadily increased the risk of dying (RR highest vs lowest category = 1.5, 95%CI: 1.1-2.0, P-trend=0.004). Especially in subjects with a high BMI, there was a positive association between WHR and mortality. The results for skinfold thickness were similar to the results for BMI, but less strong. CONCLUSIONS: In older men, BMI and skinfold thickness showed a consistent inverse association with mortality, even after accounting for early mortality. The WHR, on the other hand, was positively related to mortality, especially when BMI was high. Thus, excess abdominal fat mass (FM) warrants closer concern than being overweight, in terms of affecting mortality in the elderly.

Associations between physical activity, nutritional practices and health-related anthropometry in Flemish males: a 5-year follow-up study.

OBJECTIVE: To examine the extent to which extent health-related anthropometric characteristics such as body mass index, waist-hip ratio, waist girth, percentage of body fat and weight gain are associated with physical activity and nutritional habits in a prospective follow-up study. DESIGN: A 5-y prospective follow-up study. SUBJECTS: 132 healthy men from The Leuven Longitudinal Study on Lifestyle, Physical Fitness, and Health. MEASUREMENTS: The main outcome measures in this study were body mass index, waist-hip ratio, waist girth, percentage of body fat and significant weight gain at the ages of 35 and 40y. An unhealthy body composition was defined as a body mass index above 26, a waist-hip ratio above 0.95, a waist girth and body fat percentage above percentile 75 at the end of the 5-y follow-up period and a significant weight gain of 5 kg or more between the two examination periods. Anthropometric characteristics were derived from clinical examination. Physical activity at the age of 35 and 40 and nutritional habits at the age of 40 were determined from questionnaires. RESULTS: Physical activity was the most important predictor for the waist-hip ratio in this sample. In contrast, nutritional habits show a stronger relationship with body mass index. The absolute amount of energy intake is not as important as the dietary factors in predicting subjects with overweight or an unhealthy body composition. The index of occupational activities appears to be the most important physical activity variable. CONCLUSION: The relative contribution of physical activity and nutritional habits in health-related anthropometry varies with the characteristic considered. It is important to include all components of physical activity, and occupational activities in particular, in determining these relationships in a general population sample.

The use of anthropometry in the prevention of childhood overweight and obesity.

OBJECTIVE: To review concepts and propose measures related to the use of anthropometry for early identification of excessive weight gain in children. METHODS: Review of results from national and international studies focusing on the assessment of childhood growth, and evaluation of the weight-for-height z-scores of individual children using the 1977 National Center for Health Statistics and the 2000 Centers for Disease Control and Prevention growth charts. RESULTS: At present, few countries (23%) use indicators based on weight and height measurements to classify child body weight status. Less than one-third of growth monitoring programmes assess the growth of children beyond 6 y of age. Growth charts based on descriptive samples of populations undergoing increasing trends of childhood overweight and obesity result in substantial underestimation of true rates of these conditions. CONCLUSION: Early recognition of excessive weight gain relative to linear growth should become standard clinical practice by the following: (a) the routine collection of height measurements to enable monitoring weight-for-height and body mass index (BMI); (b) the expansion of existing monitoring programmes to include the assessment of all children up to 18 y at least once a year; (c) the interpretation of weight-for-height and BMI indices based on prescriptive reference data; and (d) the early intervention after an increase in weight-for-height or BMI percentiles has been observed.

Anthropometry-based equations overestimate the urea distribution volume in hemodialysis patients.

BACKGROUND: Protein intake in hemodialysis patients can be estimated indirectly from the protein equivalent of total nitrogen appearance (PNA) during the interdialytic period. A reliable estimate of the patient's urea distribution volume (UDV) is required to assess protein intake from PNA values. UDV values are derived frequently from simple anthropometric equations. METHODS: UDV values based on anthropometric methods were compared with UDV values determined by direct dialysate quantitation (DDQ) in 54 stable chronic hemodialysis patients. The anthropometric methods included the following: the Watson equations (WAT), a fixed proportion of postdialysis body weight, 58% for males and 55% for females (% body wt), and skinfold thickness measurements (SFT). Postdialysis blood samples were drawn at 15-minutes postdialysis. RESULTS: UDV(WAT) and UDV(SFT) overestimated UDV(DDQ) by about 8 L [limits of agreement (LOA): 2.6 to 14.2 L] in males and about 6 L (LOA: -0.8 to 12.4 L) in females. The overestimation by UDV(%BW) was even larger: 10.5 L (LOA: 2.0 to 19.0 L) in males and 11.1 L (LOA: 2.1 to 20.1 L) in females. The difference between UDV(%BW) and UDV(DDQ) correlated with the percentage of body fat (r = 0.57) and body mass index (r = 0.48). In a subgroup of seven patients, UDV was also determined by dilution (DIL) of the stable isotope [(13)C]urea. UDV(WAT) and UDV(%BW) overestimated UDV(DIL) significantly. In contrast, UDV(DDQ) was significantly smaller than UDV(DIL), even after correction for incomplete postdialysis equilibration. PNA values calculated using the various UDV estimates were compared with dietary protein intake (DPI) assessed from food records. PNA(DDQ) (61 +/- 10 g/day) did not differ significantly from DPI (63 +/- 13 g/day), but the agreement in individual patients varied considerably (LOA, -24 to 20 g/day). Anthropometric-based PNA values overestimated DPI by 8 to 16 g/day. CONCLUSIONS: Anthropometry-based equations overestimate UDV values in hemodialysis patients, leading to an overestimation of PNA values. Although PNA measurements by DDQ appear to be more reliable for assessing protein intake, PNA(DDQ) values should be interpreted with caution in individual hemodialysis patients.

Anthropometry of the trunk and extremities in nutritional assessment of children with chronic renal failure.

OBJECTIVE: Comparison of anthropometric parameters of the trunk and extremities between 2 groups of children with chronic renal failure (CRF) with different levels of nutritional status and healthy controls. DESIGN: A prospective cross-sectional study. SETTINGS: Department of Physiology and Anthropology, University Ss. Cyril and Methodius, Skopje. PATIENTS: Twenty-one patients with a mean age of 10.5 +/- 3.2 years (10 boys and 11 girls) with mild to moderate CRF were divided into well-nourished (chronic renal failure children [CRFC] I) and undernourished (CRFC II) children according to their nutritional status. The control group was 22 healthy children with a mean age of 10.7 +/- 3.8 years (10 boys and 12 girls). Nutritional status of the children was assessed by comparing anthropometric parameters with National Center for Health Statistics references. INTERVENTIONS: Anthropometry. MAIN OUTCOME MEASUREMENTS: Body weight, height, sitting height, arm and leg length, knee height, chest circumference, midarm circumference, triceps skin-fold thickness, and upper arm muscle and fat area. RESULTS: Mean sitting height, leg length, and chest circumference were significantly lower in both the CRFC I group (67.8 +/- 3.5, 57.5 +/- 4.2, and 53.0 +/- 3.9 cm) and the CRFC II group (65.6 +/- 2.2, 56.1 +/- 4.1, and 50.6 +/- 2.7 cm) compared with the healthy controls (72.5 +/- 2.9, 61.3 +/- 3.5, and 62.4 +/- 4.1 cm, respectively). The highest significant correlations to height were for sitting height (r = +0.82, P <.05) and knee height (r = +0.72, P <.05) in CRFC I and for leg length (r = +0.74, P <.05) in CRFC II. There was no correlation between anthropometric parameters of the trunk and extremities and upper muscle and fat area in both groups of CRF children. CONCLUSION: The sitting height, knee height, and leg length can be used in nutritional and growth assessment when it is impossible to make a reliable measurement of height in CRF children.
