In a study on the abdominal fat deposition measurements were carried out with computed tomography (CT) at the umbilical level in 130 patients (68 males and 62 females), submitted to the Department of Radiodiagnosis for routine CT of the abdomen. Weight, height, waist and hip circumference were measured. From a single CT scan at the umbilical level the subcutaneous and intra-abdominal fat areas were calculated. In men relatively more fat was found in the abdominal cavity than in women. Using all possible subset regression for both subcutaneous and intraabdominal fat areas, the best subsets of predictor variables were examined for males and females separately. Quetelet index and hip circumference were good predictor variables, explaining more than 70 per cent of the variance of the subcutaneous fat in both males and females. Waist and hip circumference explained about 74 per cent of the variance in intra-abdominal fat in males and 56 per cent in females. The results indicate that the single CT scan is fairly representative of overall abdominal fatness and that waist and hip circumference measurements can provide a useful indication of the abdominal fat deposition.
We examined the relation of anthropometric variables and breast cancer risk in the Epidemiological Follow-up Study of the first National Health and Nutrition Examination Survey, a cohort study based on a sample of the United States population. A total of 7149 women, 25 to 74 years of age, who were examined during the period 1971 through 1975 were included in the analysis. Stature, sitting height, elbow width, weight, and subscapular and triceps skinfold measurements were collected during the baseline interview and examination. Breast cancer cases (N = 121) were identified through hospital records or death certificates. The median follow-up period for this cohort was 10 years. Women who developed breast cancer were taller and had greater frame size (elbow width) than women who remained free of breast cancer during the follow-up period. After controlling for the effect of potential confounders, the relative risk of breast cancer was 1.9 (95% confidence interval, 1.1 to 3.1) and 2.2 (95% confidence interval, 1.3 to 3.8) among women in the fourth quartiles of stature and elbow width, respectively. Body size defined by weight, relative weight, or skinfold measurements was not associated with increased risk of breast cancer. The positive association of stature and frame size to risk of breast cancer suggests a potential role of early nutrition in cancer etiology.

A nutritional survey was conducted in the "Las Cuevas" watershed located in the southwestern region of the Dominican Republic to assess the nutritional status of preschool children. Height, weight, mid-arm circumference and triceps skinfold measurements were taken of 280 children between 6 to 54 months of age. Dietary recall was elicited from mothers or care givers. Results compared with the National Center for Health Statistics reference data indicate that these children: 1) experience growth failure and poor nutritional status as indicated by low weight for age; 2) suffer chronic malnutrition as revealed by low height for age and reduced muscle mass of the mid-arm; and 3) have appropriate weight for height measurements. A food frequency survey revealed that these children consume a diet high in carbohydrates and low in animal protein. Breast feeding is a common practice although cow's milk was introduced early in 25% of the sample. The mean age at weaning is 12 months. The results indicate that these children experience the greatest growth deficits in the second year of life and that these deficits are indicative of chronic undernutrition rather than acute food shortage or recent disease episodes. This study was carried out to establish baseline data for a resource management project initiated by the Secretariat of Agriculture of the Dominican Republic.
This article deals with the effects of conventional strength training and circuit resistance training on changes in body composition parameters. Recent data are provided on the technique of arm radiography to quantify changes in arm muscle and fat following strength development with hydraulic resistance exercise equipment.

A study was conducted on a group of full term pregnant women in the gynaecology and obstetrics ward of the Assisi Hospital. The study included the anthropometric evaluation and a survey including information on eating habits, life styles, nutrition knowledge, food preferences and aversions during pregnancy, use of oral contraceptives, and cigarette smoking. A subset of 20 pregnant women was examined periodically from the beginning of the 2nd trimester until the end of pregnancy to ascertain anthropometric status and food consumption. In the same hospital the anthropometric measurements of 83 newborns were taken. In some cases there was a relatively small weight gain and therefore gain in body fat during pregnancy (6.3 kg), with obvious effects on the weight of their respective newborns. Eating habits showed notable quantitative and qualitative irrationalities and nutrition knowledge was poor. Oral contraceptives were not widely used.
