Static anthropometry of civilian Chinese in Taiwan using computer-analyzed photography.

The purpose of this study was to establish a static anthropometric data bank for Chinese civilians in Taiwan using a computer-analyzed photographic method. Stratified random sampling was applied to decide the sampling site; sample size was established by considering standard errors in a pilot study. Then a photographic method was employed in addition to direct measurement of selected body dimensions. In all, 933 subjects were measured. The data were entered via a digitizer into a microcomputer for processing. The resulting anthropometric data bank was organized by age, sex, and occupational groupings. Comparisons with data from previous studies were made, and recommendations for further research presented.

Anthropometry of seated women during pregnancy: defining a fetal region for crash protection research.

An anthropometric description was developed for the fetal region of women at three, six, and nine months of pregnancy. This involved superimposing a fetal ellipse on abdominal and pelvic ellipses of seated women from a previous study. The data were developed for women of 5th, 50th, and 95th percentile size. The ellipses identify body contact zones on the side and front which would interact with the fetal region in a crash. The new information provides spatial characteristics of pregnant women for the development of test dummies, accommodating restraints, and friendly interiors and for enhancing crash protection. This research addresses the 342 deaths of pregnant women estimated to occur annually in motor vehicle crashes.

Routine anthropometry and arm radiography in assessment of nutritional status: its potential.

Elementary anthropometric and radiographic techniques, carefully executed and routinely employed in definitive surveys of healthy persons, are of potential value in assessment of patients, and provide the following: 1. Formulas to compute mean "ideal body weights" of young adults from stature (W = kh1.7). 2. A "unit size-weight" index (uS-W) with a mean value of 100 or nearly identical to 100 for all mean "ideal weights" relative to stature. 3. The distribution of values of the uS-W index for 80 and 90% of the population of young adults around the mean. 4. Conversion of body girths and stature to ponderal equivalents such that component A reflects fatness (if present) and component B, leanness and muscularity. 5. Conversion of skeletal diameters and stature to a relative "frame" size weight, designated component C, and employed as a "reference weight" (Ref W) for the calculation of lean body weight (LBW) in the male, and "minimal weight" as well as LBW in the female. 6. Conversion of skinfold thickness to estimates of body fat by means of a surface area formulation where: Weight of fat = SA x skinfold widths x k(fat). 7. The introduction of comprehensive arm radiography to reveal presumptive estimates of body fat from SA and of the amount of bone and muscle in the arm to LBW. 8. The visualization of body shape in the somatogram, and the value of photography under strictly controlled conditions.

Anthropometry measures and prevalence of obesity in the urban adult population of Cameroon: an update from the Cameroon Burden of Diabetes Baseline Survey.

BACKGROUND: The objective of the study was to provide baseline and reference data on the prevalence and distribution of overweight and obesity, using different anthropometric measurements in adult urban populations in Cameroon. METHODS: The Cameroon Burden of Diabetes Baseline Survey was a cross-sectional study, conducted in 4 urban districts (Yaoundé, Douala, Garoua and Bamenda) of Cameroon, using the WHO Step approach for population-based assessment of cardiovascular risk factors. Body mass index, waist circumference and waist-to-hip ratio were measured using standardized methods. Overall, 10,011 individuals, 6,004 women and 4,007 men, from 4,189 households, aged 15 years and above participated. RESULTS: Based on body mass index, more than 25% of urban men and almost half of urban women were either overweight or obese with 6.5% of men and 19.5% of women being obese. The prevalence of obesity showed considerable variation with age in both genders. Using body mass index provided the highest prevalence of obesity in men (6.5%) and waist-to-hip ratio the lowest prevalence (3.2%). Among women, using waist-to-hip ratio and waist circumference yielded the highest prevalence of obesity (28%) and body mass index the lowest (19.5%). There was a trend towards an increase in age-adjusted odd ratios of being overweight or obese with duration of education in both sexes. CONCLUSION: The study provides current data on anthropometric measurements and obesity in urban Cameroonian populations, and found high prevalences of overweight and obesity particularly over 35 years of age, and among women. Prevalence varied according to the measure used. Our findings highlight the need to carry out further studies in Cameroonian and other Sub-Saharan African populations to provide appropriate cut-off points for the identification of people at risk of obesity-related disorders, and indicate the need to implement interventions to reverse increasing levels of obesity.

Time course of catch-up in adiposity influences adult anthropometry in individuals who were born small for gestational age.

Although necessary for a normal final height in individuals who were born small for gestational age (SGA), catch-up growth is associated with drastic changes in body composition that have been suspected to favor the later development of the long-term metabolic complications by promoting central adiposity; however, the specific contribution of catch-up itself on these later complications remains unclear. Therefore, the aim of the study was to characterize the dynamic changes in adiposity during childhood in individuals who were born SGA and to investigate their consequences on adulthood. The magnitude and the time course of postnatal changes in body mass index (BMI) relative to birth and their consequences on adult adiposity were investigated in 127 adults who were born SGA and had available serial anthropometric data in childhood (0-6 y) and adulthood. Catch-up in BMI, observed in 91% of individuals who were born SGA, was mostly completed within the first or second year of age. Overall, adult BMI was correlated with the magnitude of gain in BMI during childhood. However, this effect was significant only when this gain persisted after the first year of life. Similarly, the influence of the magnitude in gain in BMI on the risk for adult BMI >25 kg/m(2) was significantly influenced by the age at which the gain in BMI occurred. In summary, although the extent of catch-up in BMI affects adiposity in adulthood, this effect is mostly deleterious when occurring after 1 y of age, suggesting that a rapid catch-up process should be more suitable than a delayed one. Whether this observation holds through regarding the metabolic syndrome remains to be elucidated.

Resistin in preterm and term newborns: relation to anthropometry, leptin, and insulin.

This study aimed to investigate 1) the plasma resistin concentration at birth, 2) the relationship of resistin with leptin and insulin, and 3) the association of resistin with anthropometric indexes in newborn infants. Blood samples for hormonal assay were obtained from preterm and term newborns within the first 2 h of life and before milk feeding or energy intake. Although these infants required blood sampling for clinical reasons, all were proved to be noninfected. Plasma resistin was significantly higher in term than in preterm infants. It was also significantly correlated with serum leptin, and both hormones were significantly associated with gestational age and anthropometric indexes. Infants who were born vaginally were found to have significantly higher plasma resistin levels compared with those who were born by cesarean section. In the multivariate forward stepwise regression models, resistin was found to be significantly associated with the mode of delivery and gestational age or birth weight. The association among resistin, leptin, and anthropometric indexes suggested that both hormones might be gestation related. A high circulating resistin level at term gestation could be advantageous to the infant by promoting hepatic glucose production and preventing hypoglycemia after birth. Infants who were born vaginally had significantly higher plasma resistin levels, suggesting that this hormone might also be associated with stress or inflammation induced by the birth process.

Changes in anthropometry with testosterone therapy in a female with gender identity disorder.

A 31-year-old regularly menstruating Japanese female was referred to our outpatient clinic by a psychiatrist. She had been diagnosed as having gender identity disorder by detailed counseling and clinical intervention 3 years earlier. After obtaining fully informed written consent, we treated her with 125 mg of testosterone enanthate, intramuscularly, every 2 weeks for 4 months. Serum testosterone levels increased to the normal male value (from 28 to 432 ng/dL). Although menstrual cycle remained regular, her voice became lower after 4 months of therapy. Body weight, body mass index, and lean body mass increased, while body fat mass and percentage of body fat decreased. However, trunk-leg fat ratio did not change during the observation period. During testosterone therapy, a disproportionate increase in lean body mass and decrease in body fat mass are early onset events, while the shift toward upper body fat distribution may be a late onset event along with increase in BMD.

Anthropometry in skeletal dysplasia.

Skeletal dysplasia or osteochondrodysplasia is the designation of more than 200 different disorders, that are characterized by abnormalities of the skeleton, disproportional short stature, and a variety of other problems. The underlying biochemical defect is unknown in the vast majority of skeletal dysplasias, and the diagnosis is based on radiological findings and anthropometric measurements. Despite this fact, the information on body proportions in even the more common forms of skeletal dysplasia is scarce. Patients with achondroplasia are often diagnosed shortly after birth. Linear growth is severely compromised with relatively short extremities. Head circumference is above normal and final height ranges from 115 to 145 cm in males and 112 to 137 cm in females. Individuals with hypochondroplasia may go unnoticed until puberty, at which time the growth problem becomes obvious. Sitting height to height ratio is increased, but the body disproportion may not be apparent until puberty. Final height has been reported between 118 and 165 cm. Spondyloepiphyseal and spondylometaepiphyseal dysplasias are characterized by severe impairment of growth both in trunk and extremities, and therefore the sitting height to height ratio may be normal. Final height is severely reduced and ranges from 94 to 132 cm. It is concluded that anthropometric studies of patients with skeletal dysplasia are needed. More quantitative information on body proportions may assist in the diagnostic procedure and ensure that growth promoting therapy, e.g. growth hormone, does not worsen the disproportion.

Thigh-muscles strength training, dance exercise, dynamometry, and anthropometry in professional ballerinas.

The purpose of the present study was to assess the effects of 12 weeks of quadriceps and hamstring strength training on torque levels after a dance exercise and on selected anthropometric parameters. The sample consisted of 22 (ages, 25 +/- 1.3 years) full-time professional ballerinas who were randomly assigned into experimental (n = 12) and control (n = 10) groups. A dance routine designed to cause fatigue within 5 minutes, isokinetic dynamometry, and anthropometric assessments were conducted before and after strength training in both groups. Before strength training, the dance routine resulted in significant reductions of hamstring (p < 0.001) and quadriceps (p < 0.001) peak torques in both subject groups. However, after strength training, only control subjects demonstrated such torque decrements (p < 0.001) after the dance routine. Furthermore, the experimental group revealed greater knee extension (119 vs. 138 N.m; p < 0.001) and flexion (60 vs. 69 N.m; p < 0.001) torques, smaller sum of skinfolds (33.6 vs. 27.8 mm; p < 0.01), more fat-free mass (37.7 vs. 39.4 kg; p < 0.05), but unchanged body mass (p > 0.05) and thigh circumferences (p > 0.05). A negative relationship (p < 0.001) was found between initial strength levels and improvements measured at the end of the 12-week program. These results suggest that supplementary strength training for hamstring and quadriceps muscles is beneficial to professional ballerinas and their dancing; weaker individuals are more likely to benefit from such regimens than their stronger counterparts, whereas increases in thigh-muscle strength do not alter selected aesthetic components.

Prediction of one repetition maximum strength from multiple repetition maximum testing and anthropometry.

The purpose of this study was to quantify the decrease in the load lifted from 1 to 5, 10, and 20 repetitions to failure for the flat barbell bench press (chest press; CP) and plate-loaded leg press (LP). Furthermore, we developed prediction equations for 1 repetition maximum (RM) strength from the multiple RM tests, including anthropometric data, gender, age, and resistance training volume. Seventy subjects (34 men, 36 women), 18-69 years of age, completed 1, 5, 10, and 20RM testing for each of the CPs and LPs. Regression analyses of mean data revealed a nonlinear decrease in load with increasing repetition number (CP: linear S(y.x) = 2.6 kg, nonlinear S(y.x) = 0.2 kg; LP: linear S(y.x) = 11.0 kg, nonlinear S(y.x) = 2.6 kg, respectively). Multiple regression analyses revealed that the 5RM data produced the greatest prediction accuracy, with R(2) data for 5, 10, and 20RM conditions being LP: 0.974, 0.933, 0.915; CP: 0.993, 0.976, and 0.955, respectively. The regression prediction equations for 1RM strength from 5RM data were LP: 1RM = 1.0970 x (5RM weight [kg]) + 14.2546, S(y.x) = 16.16 kg, R(2) = 0.974; CP: 1RM = 1.1307 x (5RM weight) + 0.6999, S(y.x) = 2.98 kg, R(2) = 0.993. Dynamic muscular strength (1RM) can be accurately estimated from multiple repetition testing. Data reveal that no more than 10 repetitions should be used in linear equations to estimate 1RM for the LP and CP actions.

[Plasma zinc levels and the anthropometry of children in the outskirts of urban centers in Brazil].

The main objective of the present study was to estimate plasma zinc concentration in children belonging to low-income families residing in three different neighborhoods on the outskirts of Ribeirão Preto, SP, Brazil, and to determine a possible correlation of this parameter with several anthropometric measurements. Plasma zinc levels were lower than 70 micrograms% in 13% of the children studied. Weight for age, height for age and weight/height ratio were below 90% of the 50th percentile of National Center for Health Statistics (NCHS) in 42.9%, 6.3% and 9.5% of children, respectively. Tricipital fold, arm circumference and muscle circumference were also below 90% of the 50th percentile in 65.8%, 11.0% and 7.3% of the children, respectively. No correlation was observed between plasma zinc levels and the anthropometric parameters studied.
