Book excerpt: "A strong association exists between childhood and adult obesity trends, so physicians are being encouraged to track children's growth patterns, especially for weight, but the doctor's office may not be the most efficient place to follow large groups of children. They might see a child once a year whereas a teacher sees a child everyday. There is agreement that the application of early screening in schools is important in the attempt to identify those individuals who may currently be overweight or obese. Tracking students' weight, or even better, their body composition, in the school setting is probably the best place to follow this large, diverse population, but at the present time there is little agreement about the best way to measure them. The debate centers on how, not if tracking should be done. Therefore this research attempted to cross validate the Tanita (TBF-300A) bioelectrical impedance analyzer in boys and girls ages 12-14 compared to the BOD POD. Twenty-four boys and girls currently enrolled in a fitness and health class at Glover Middle School volunteered. Following the original discussion with the students and their parents through a letter, the 24 students who returned all completed forms were included in the trip to the Human Performance Lab at Eastern Washington University. Eleven students completed all testing following a random assignment for the order of testing. The two methods included the method currently being used in the district, bioelectrical impedance, and air displacement plethysmography. The level of significance was set a-priori at p

This book was released on 2007 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Bioelectrical Impedance Analysis (BIA) is a method of body composition assessment that measures conductance and resistance of low voltage electrical current passed through the body[1-3]. While various methods using BIA have been shown to be accurate and reliable[1, 3-9], the InBody BIA (BioSpace, Korea) has not been validated against other currently accepted methods of body composition analysis. Body composition was measured using two methods of BIA, the InBody model 320 and model 720, as well as skinfold measurements, air displacement plethysmography (BodPod), and hydrostatic weighing. A total of 67 male and female subjects between the ages of 18-25 with normal to overweight body mass indices (BMI between 18.5-29.9) were recruited for the study. For both BIA models, there were no significant differences in percent body fat measurements when compared with skinfold measurements, air displacement plethysmography, and hydrostatic weighing, and both methods were significantly correlated with each. Based on the present results, the InBody 320 and 720 models may be used for the valid measurement of adults between 18-25 years of age with a normal to overweight BMI.

Available in PDF, EPUB and Kindle. Book excerpt: Obesity has increased exponentially within the last three decades and is now widely recognized as one of today's leading health threats due to it being a risk factor for diseases such as type 2 diabetes, cardiovascular disease, and hypertension. In recent years, there have been advances in technology such as bioelectrical impedance analysis (BIA), dual-energy X-ray absorptiometry (DEXA), and air displacement plethysmography that has been used to categorize individuals into percent fat categories. However, there are still concerns with the validity of these devices. PURPOSE: The purpose of this study was to analyze the validity of the InBody 520, BodPod, and Hologic DEXA against hydrostatic weighing. METHODS: 32 male and 30 female subjects performed body composition testing using the InBody 520, BodPod, Hologic DEXA, and hydrostatic weighing. RESULTS: The constant error values and mean values for percent body fat were the highest amongst the DEXA compared to the InBody and BodPod. The InBody showed a non-significant relationship (p=0.11, p= 0.47, and p=0.26) between constant error values and percent body fat values for hydrostatic weighing for females, males, and all subjects respectively. The BodPod showed a significant negative relationship (p=0.04 and p

Available in PDF, EPUB and Kindle. Book excerpt: This book is the compilation of papers presented at the International Symposium on In Vivo Body Composition Studies, held in Houston, Texas, November 10-12, 1992. The purpose of this conference was to report on the state-of-the-art techniques for in vivo body composition measurements and to present the most recent human data on normal body composition and changes during disease. This conference was the third in a series of meetings on body composition studies held in North America, and follows the successful meetings at Brookhaven National Laboratory in 1986, and the one in Toronto in 1989. A large number of excellent research papers were offered for consideration at this Conference which demonstrates the rapid growth of the field in the last three years. However, we had to limit the presentations to approximately 90 papers which provided a broad spectrum of the applications and recent interest in the subject. The proceedings of the Brookhaven meeting "In Vivo Body Composition Studies", is published by The Institute of Physical Sciences in Medicine, London. The proceedings of the Toronto meeting "In Vivo Body Composition Studies" was published by Plenum Press in its basic life science series. Both these meetings placed more emphasis on technical aspects while the current Houston meeting tried to emphasize more the emerging clinical applications of these techniques. The general sessions used at the Conference for presentations forms the basis of the order of appearance of the papers in this book.

This book was released on 2015-04-27 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Childhood obesity according to the World Health Organization is one of the most serious public health challenges of the 21st century. The proportion of childhood obesity is high both globally and in Sweden. This is of great concern since obese children tend to stay obese in adulthood. In order to develop strategies to prevent early childhood obesity more knowledge is needed regarding factors explaining why children become overweight and obese. Preventive strategies require accurate and easy-to-use methods to assess physical activity in response to energy expenditure as well as energy intake in young children, but such methods are largely lacking or have shown limited accuracy. The aims of this thesis were: 1) to describe the longitudinal development of body composition from 1 week to 4.5 years of age; 2) to study relationships between measures of body composition and the physical activity level (PAL) at 1.5 and 3 years of age; 3) to evaluate if heart rate recording and movement registration using Actiheart can capture variations in total energy expenditure (TEE) and activity energy expenditure (AEE) at 1.5 and 3 years; 4) to evaluate the potential of a 7-day activity diary to assess PAL at 1.5 and 3 years of age; 5) to evaluate a new tool (TECH) using mobile phones for assessing energy intake at 3 years of age. Healthy children were investigated at 1 and 12 weeks (n=44), at 1.5 (n=44), 3 (n=33) and 4.5 (n=26) years of age. Body composition was measured using air-displacement plethysmography at 1 and 12 weeks and at 4.5 years of age. At 1.5 and 3 years, body composition, TEE, PAL and AEE were assessed using the doubly labelled water method and indirect calorimetry. Heart rate and movements were recorded using Actiheart (four days) and physical activities were registered using the 7-day diary. Energy intake was assessed using TECH during one complete 24-hour period. Average percentage of total body fat (TBF) and average fat mass index (FMI) were higher (+3 to +81 %), while fat-free mass index (FFMI) was slightly lower (-2 to -9 %), in children in the study from 12 weeks until 4.5 years of age when compared to corresponding reference values. A relationship between TBF% and PAL was found both at 1.5 and 3 years of age. At 3 years, but not at 1.5 years, this could be explained by a relationship between PAL and FFMI. Actiheart recordings explained a significant but small fraction (8%) of the variation in free-living TEE at 1.5 and 3 years, and in AEE (6 %) at 3 years, above that explained by body composition variables. At 1.5 and 3 years of age, PAL estimated by means of the activity diary using metabolic equivalent (MET) values by Ainsworth et al. was not significantly different from reference PAL, but the accuracy for individuals was low. Average energy intake assessed by TECH was not significantly different from TEE. However, the accuracy for individuals was poor. The results of this thesis suggest that 1) The higher body fatness of the children in the study compared to the corresponding reference values may indicate the presence of a secular trend in body composition development characterized by a high body fatness. 2) Body fatness might counteract physical activity at 1.5 years of age when the capacity to perform physical activity is limited, but not at 3 years of age when such a capacity has been developed. 3) Actiheart recordings explained a significant but small fraction of the variation in TEE at 1.5 and 3 years, and in AEE at 3 years of age, above that explained by body composition variables. 4) The activity diary and TECH produced mean values in agreement with reference PAL and TEE, respectively, but the accuracy for individual children was low. In conclusion, the results of this thesis suggest the presence of a secular trend in body composition development in healthy Swedish children, from infancy up to 4.5 years of age, which is characterized by a high body fatness. Methods to assess physical activity and energy intake at 1.5 and 3 years of age provided some promising results on a group level, although further research is needed to increase the accuracy of these methods in individual children.

This book was released on 2014 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the use of body composition analyzers can become a critical tool in breaking the continual weight loss/weight gain cycle in Americans, the accuracy of these analyzers at measuring body composition remains in question. PURPOSE: The purpose of this study was to determine the effectiveness of various body composition techniques at determining body fat percentages (%BF). METHODS: Sixty males (mean +/- SD) [age: 21.3 +/- 1.7 yr., height: 178.1 +/- 7.2 cm., mass: 81.9 +/- 12.6 kg., body fat %: 14.6 +/- 7.5 %] and thirty-nine females [age: 20.5 +/- 0.9 yr., height: 166.0 +/- 7.7 cm., mass: 63.5 +/- 11.6 kg., body fat %: 26.6 +/- 6.7%] from a moderately sized, midwestern university participated in the study. Height and weight were obtained followed by six different body composition assessment techniques: Underwater Weighing with predicted residual volume (UWW-PredRV), Underwater Weighing with estimated residual volume (UWW-ForcedVC), Air Displacement Plethysmography (ADP), Bioelectrical Impedance (BIA) using Tanita analyzer (Tanita), BIA using Omron lower body analyzer (OmronLB), and BIA using Omron lower body/upper body analyzer (OmronLBUB). RESULTS: Two-way ANOVA with repeated measures detected significant differences (p
