[Evaluation of nutritional status of adult middle class healthy subjects. Energy and protein intake, anthropometry, blood biochemical tests, and immunocompetence tests].

Nutritional status was assessed in 151 middle-class healthy adult individuals (69 medical students, 18-29 y, 34 males, 35 females); 48 university personnel, 30-49 y, 24 males, 24 females; and their older relatives, 34 subjects, 50-79 y, 19 males, 15 females) living in Botucatu, S. Paulo. Methods included anthropometric measurements, energy and protein intakes, blood biochemical analyses and cutaneous delayed hypersensitivity tests. Anthropometric measurements showed higher values in men, with the exception of the triceps skinfold thickness (higher in women) and of the arm fat area (higher in the older age female groups); aging seemed to be associated with increases of weight, arm muscle variables and with arm fat accumulation in women and with increases of arm muscle variables in men. The values for anthropometric measurements were in general higher than those found in other Brazilian studies; on the other hand, they approximate to but do not entirely agree with the data representative of the international referential adult population: differences were mainly concerned with body weight and upper arm muscle parameters, which were lower in our sample. As regards energy intake, values found in subjects under 50 years of age were lower than the recommended dietary allowances; averages found for protein intake were above the level recommended by WHO/FAO/UNU (1985). The mean values for serum proteins and lipids were similar to those of referential data. As regards the hypersensitivity tests, it was found that none of the individuals challenged with four antigens (PPD, Candidin, Vaccinia and phytohemagglutinin) presented less than two positive skin reactions.(ABSTRACT TRUNCATED AT 250 WORDS)

[Anthropometry of elderly people living in geriatric institutions, Brazil].

OBJECTIVE: To provide anthropometric and body composition information on elderly people living in geriatric institutions. METHODS: Three-hundred and five elderly people, of both sexes, living in six geriatric institutions in Fortaleza were assessed. The following anthropometric variables were studied: weight, height, body mass index, mid-arm circumference, triceps skinfold thickness, arm muscle circumference, and corrected arm-muscle area. The body mass index was calculated as weight divided by the square of the height (m2). The arm muscle circumference and corrected arm-muscle area were calculated using specific equations. The results are presented as means, standard deviations and percentiles (5th, 10th, 25th, 50th, 75th, 90th and 95th). The analyses included Student t-test to detect differences in mean values of the variables between both sexes. Age impact was investigated by ANOVA. RESULTS: In all variables, mean values in men were higher than those in women, except for triceps skinfold thickness . The mean difference of the variables body mass index and mid-arm circumference for both sexes were not statistically significant (p>0.05). Age has significantly contributed to reducing the variables' values. This means that specific reference standards are needed for elderly people. CONCLUSIONS: Despite being institutionalized, there was seen a trend of decreasing anthropometric values in the study population similar to that found in other studies of elderly people but with different values. Thereby, such values could be useful in the nutritional assessment of institutionalized elderly people.

[Human ecology and nutritional anthropometry of adult Xavánte Indians in Mato Grosso, Brazil].

This study compares anthropometric and ecological profiles of two Xavánte indigenous communities in Mato Grosso, Central Brazil. The research describes time allocation patterns and involves an anthropometric survey (including body mass, stature, and BMI) in adults over 20 years of age. Data from Etéñitépa (also known as Pimentel Barbosa) were collected in 1994. Field work at São José was conducted in 1998 and 1999. Compared with the São José group, Xavánte in Etéñitépa do more subsistence activities like farming, fishing, hunting, and gathering. The São José Xavánte do more paid work and generally engage in less physical activity. Average stature in the two communities is similar, but there are major differences in mean body mass and BMI. The São José group has average BMI values well over those of the Etéñitépa group in practically all age brackets. Obesity prevalence rates were high in both men (24.6%) and women (41.3%) in São José, while in Etéñitépa the rates were only 2.5% and 4.8%, respectively. The authors conclude that the different nutritional profiles in the two communities result from specific patterns of social, political, and economic interactions with Brazilian society.

Anthropometry of elderly residents in the city of São Paulo, Brazil.

The article presents gender and age-specific selected anthropometric data for a representative sample of elderly Brazilians in the city of São Paulo. This was a cross-sectional, population-based household survey. A total of 1,894 older adults (men and women, > 60 years) were examined from January to March 2001. Data were presented as means and percentiles for body mass (BM); height or stature (ST); body mass index (BMI); waist (WC), hip (HC), arm (AC), and calf (CC) circumferences; triceps skinfold thickness (TST); and arm muscle circumference (AMC), and differences were described according to age (all variables) and gender (BMI). Except for HC (men), all anthropometric variables were lower in the oldest than in the youngest individuals (p < 0.01) in both genders. BMI was significantly higher (p < 0.01) in women than men (all age groups). The observations suggest that there is loss of muscle mass and redistribution and reduction of fat mass with age (both genders). The data can be used in clinical practice and epidemiological studies based on interpretation of anthropometric measurements in the elderly in São Paulo.

Development of a prediction equation for insulin sensitivity from anthropometry and fasting insulin in prepubertal and early pubertal children.

OBJECTIVE: To test the utility of homeostasis model assessment (HOMA) in predicting insulin sensitivity [x10(- 4) min(-1)/(microIU/ml)] in children and to develop and compare two new prediction equations for insulin sensitivity in children using demographic and anthropometric measures in the presence or absence of fasting insulin. RESEARCH DESIGN AND METHODS: We studied 156 white and African-American children with complete data (mean age 9.7 +/- 1.8 years, 87.8% Tanner Stage 1 or 2). For development of new equations, two-thirds of the children were randomly assigned to a development group, whereas the remaining children were assigned to a cross-validation group. RESULTS: A modified HOMA equation accurately predicted insulin sensitivity, but its utility is similar to fasting insulin alone. Demographic and anthropometric measures alone did not predict insulin sensitivity accurately, even when precise measures of body composition were included in the prediction model. Ethnicity, calf skinfold, and fasting insulin together explained 73% of the variance in insulin sensitivity and accurately predicted insulin sensitivity. The regression of measured versus predicted insulin sensitivity in the cross-validation group was not significantly different from the line of identity (P > 0.05). Mean difference between measured and predicted insulin sensitivity was also not significant (P > 0.05). Some bias was apparent, particularly in white boys. CONCLUSIONS: Ethnicity, calf skinfold, and fasting insulin can accurately predict insulin sensitivity with greater precision than HOMA or fasting insulin alone (R(2) = 0.73). Future studies, however, are needed to examine whether a universal equation is possible. A cross-validated prediction equation may be useful in population-based studies when complex measures of insulin sensitivity are not available.

Anthropometry and adiposity in a group of people with chronic mental illness.

OBJECTIVE: The prevalence of excess body weight has been reported as two to four times greater in the chronic mentally ill than in the general population. However, there has been a paucity of body composition research with this population. The purpose of this study was to compare with population data the prevalence and distribution of body fat in a group of chronic mentally ill individuals. METHOD: An anthropometric profile consisting of height, weight, waist and hip girths was completed on 29 males and 23 females. RESULTS: Consistent with other groups with excess adiposity, measures of skinfold thickness were generally unreliable. The biceps was the only site where a reliable skinfold measure was possible in all subjects. More than half of the males and three-quarters of the females had a waist circumference in excess of 100 cm. CONCLUSIONS: There were significantly higher levels of relative body weight and excess abdominal adiposity in the study group compared with the wider population. A brief anthropometric protocol of waist and hip girths and biceps skinfold in addition to height and weight, rather than the use of weight alone as an indicator of adiposity, is recommended.

Maternal anthropometry and pregnancy outcomes: a proposal for the monitoring of pregnancy weight gain in outpatient clinics in South Africa.

The aim of this review was to develop a framework for the monitoring of pregnancy weight gain in South African outpatient clinics. Studies showed that intrauterine malnutrition have more serious consequences for children than postnatal malnutrition. Undernutrition, as well as overnutrition during pregnancy, was associated with adverse pregnancy outcomes. The IOM published recommended weight gains by pre-pregnancy body mass index (BMI). Wasting in pregnant women can be defined as a mid-upperarm circumference (MUAC) < 22cm. Low prepregnancy BMI is considered a risk factor for preterm birth and intra-uterine growth retardation. Pregnant women in developing countries start to attend antenatal clinics late in pregnancy, so that prepregnancy BMI may be unknown and antenatal care can be based on pregnancy weight gain only. A framework is proposed that identifies the critical points for action during pregnancy to improve birth outcomes. Health care providers should measure height, weight and MUAC and try to classify pregnant women according to weight status, set weight gain goals and monitor gestational weight gain between follow-up visits. Women with short stature (< 145cm), low body weight (< 45kg), and/or MUAC < 22cm are considered to be at risk of adverse pregnancy outcomes. Weekly weight gains should range from 0.3kg for overweight women to 0.5kg or more for underweight women from the second trimester. Genetic background, age, general health, HIV and educational status, cigarette smoking, past nutritional status of the mother, parity, multiple pregnancies, climate, socioeconomic conditions and the availability of health services should be adjusted for in statistical analyses.

Cross-sectional anthropometry: what can it tell us about the health of young children?

It has become common practice in health surveys to collect anthropometric measurements from young children. These datasets comprise one-point-in-time measurements for a number of children, and are very different in character from longitudinal data such as those collected during growth monitoring. This paper explores the nature of cross-sectional data, their applications and their limitations, using sample data from Burundi, Uganda and Zimbabwe. Methods of analysis which treat the data as continuous or dichotomous are compared. The conclusion is that cross-sectional data can make a valuable contribution to health research provided their application and interpretation are properly understood.

[Nutritional anthropometry and physical performance in urban adolescents of Madrid].

OBJECTIVE: This work has been carried out as a cooperation project between University and High School Departments. Its objective was to evaluate the nutritional and physical status and eating habits in an urban adolescent population of Madrid. The study presents data about anthropometrical analyses and physical performance. SAMPLE AND METHODS: The sample analyzed was composed of 183 males and 222 females between 14 and 18 years of age. The nutritional status was analyzed by means of stature, weight, skinfold thickness and arm circumference, body mass index (BMI), and lean, fat and total upper arm areas. For physical fitness analysis, the EUROFIT battery was used (plate tapping, trunk and arm flexion, 10 x 5 run, horizontal jump, abdominals in 30 seconds and manual dynamometry). RESULTS AND CONCLUSIONS: With regard to the anthropometric characteristics and physical fitness, the analyzed population is slightly above the reference standard, mainly in the youngest age studied. Percentage of obese subjects was 14.7% in males and 5.8% in females. In regard to physical fitness, the males surpassed the 50th percentile of the EUROFIT battery in almost all of the trials. The average in the female subjects was slightly inferior to the reference standards.

Measurement of obesity by anthropometry and bioelectric impedance analysis: correlation with fasting lipids and insulin resistance in an Asian population.

Obesity is associated with increased coronary artery disease risk. This is at least partially mediated by increased prevalence of other risk factors such as dyslipidaemia and insulin resistance. Various anthropometric indices have been used to quantify generalised and central obesity. Correlations between these measurements and risk factors are specific to the population and findings cannot be extrapolated to other ethnic groups. Bioelectric impedance analysis (BIA) is a simple means of estimating percentage body fat. We compared body mass index (BMI), waist circumference, waist-hip ratio (WHR) and percentage body fat measure by BIA as predictors of fasting lipid profiles and insulin resistance in 109 Singaporean Chinese. BMI was significantly correlated with insulin resistance and there appeared to be a threshold at 26 kg/m2 above which the regression line became more steep. WHR best predicted fasting triglyceride in both men and women. In women, it was inversely correlated with high density lipoprotein cholesterol. A similar association was seen in men but this did not reach statistical significance. We conclude that measurement of BMI and WHR should be part of the assessment of cardiovascular risk in our population as they connote different aspects of risk. BIA was not found to be a useful tool for the prediction of coronary artery disease risk factors in our population.

[Anthropometry and body composition in persons over 60. The importance of physical activity].

OBJECTIVE: To measure anthropometric indicators of body composition by electric bioimpedence, as well as physical activity, blood glucose and arterial pressure in rural people over 60 years of age. MATERIAL AND METHODS: A total of 54 subjects over 60 years old were selected by intentional non-probabilistic sampling. They were subjected to a standardized protocol to measure anthropometric indicators, body composition by electric bioimpedance (EBI), and physical activity was determined by an activity questionnaire. Arterial pressure and glucose tolerance levels were also measured. Analysis included Student's t test to detect differences by sex and the association of physical activity, body composition and other variables by simple linear regression and Pearson's correlation coefficient. RESULTS: Physical activity correlated negatively with percent fat (r = -0.36; p = 0.007) and diastolic (r = -0.36; p = 0.006) and systolic blood pressure (r = -0.32; p = 0.018), and body mass index with post dose glucose (r = 0.31; p = 0.024). CONCLUSIONS: Physical activity in this age group may have a favorable impact with respect to the mentioned health indicators.

[Changes of body fat mass determined by be-electrical impedance and by anthropometry: BMI method and skinfolds method in overweight and obese women after implementation of low energy diet].

OBJECTIVE: To estimate the effect of a low energy diet on body fat mass measured by bioelectrical impedance (BIA) in overweight (BMI > or = 25 < 30) and obese women (BMI > or = 30). DESIGN: Randomised six weeks trial. METHODS: The studied group consisted of 86 women aged 20-67 attended the Outpatients Clinic of Metabolic Disorders. Dietary assessments were performed by 24-hour dietary recall. Body fat mass was measured by bioelectrical impedance method and by skinfolds thickness method. Percent body fat and fat free mass was estimated from equations based on BMI and skinfolds thickness. RESULTS: In overweight women after 6 weeks of dietary treatment mean intake of energy decreased from 10071 +/- 2678 kJ to 4560.6 +/- 1405.8 kJ, total fat intake from 88.7 +/- 33.9 g/d (33.4% of energy) to 38.8 +/- 19.9 g/d (31.1% of energy), protein intake from 89.5 +/- 36.5 g/d (14.8% of energy) to 50.7 +/- 16.9 g/d (19.0% of energy), carbohydrates intake from 312.7 +/- 106.6 g/d (51.8% of energy) to 134.5 +/- 53.7 g/d (50% of energy). In obese women mean intake of energy decreased from 10,376.3 +/- 2953.9 kJ to 4665.2 +/- 1380.7 kJ. The value of total energy, total fat and saturated fatty acids intake correlated with body weight, BMI and body fat. After dietary treatment the body weight decreased by 2.4 kg (3.3%) in overweight women and by 3.9 kg (4.1%) in obese women and percent of body fat decreased by 1.6% and 2.3%, respectively. Body fat mass determined by BIA method significantly correlated with skinfolds method by Siri, Schutte, Rathbun, Brozek, Keys-Brozek, and BMI method by Webster, Deurenberg. CONCLUSION: BIA method may be a helpful tool for the analysis of changes in total body composition occurring under obesity treatment.

[Anthropometry and the reference values of body composition by bioelectrical impedance in the adult population of L'Hospitalet de Llobregat].

BACKGROUND: The aim of the present study was to assess the anthropometric variables and the reference values of body composition in the adult population of L'Hospitalet de Llobregat, due to the lack of epidemiological studies on this matter in Spain. PATIENTS AND METHODS: We studied 234 normal subjects, 134 males, mean age 41.4 years, and 134 females, mean age 40.7 years, selected from the census of L'Hospitalet de Llobregat and representative of its population in sex and age. We determined anthropometric characteristics, body weight, height, body mass index, waist-hip ratio and body composition parameters: total body water, free fat mass, fat mass and body fat by bioelectrical impedance analyzer. RESULTS: Twenty-four males and 33 females were obese, and out of them 2 males and 4 women presented morbid obesity. The body mass index was higher either in males (p = 0.017) or in females (p = 0. 0001) in the last decades in relation to first decade, and in women was as consequence of higher fat mass (p = 0.0001). The waist-hip ratio was 0.93 (0.08) in male and 0.79 (0.07) in female, and it was high in males in the last decades. CONCLUSION: The present study points out the high prevalence of obesity in our city and the anthropometric characteristics and reference values of body composition in the normal population of L'Hospitalet de Llobregat, remarking the high body mass index in the last decades, especially in women due to an increase of fat mass. The waist-hip ratio was high in males in the last decades.
