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 2019-03-12 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: In partnership with the American College of Sports Medicine (ACSM), pioneer body composition experts Timothy G. Lohman and Laurie A. Milliken, along with a team of highly regarded contributors, have compiled a practical guide to performing body composition assessments. With an easy-to-follow format and straightforward writing, ACSM’s Body Composition Assessment provides readers foundational information and scientific research with applications in the fields of medicine, exercise science, nutrition, growth and development, and geriatrics. ACSM’s Body Composition Assessment delves into the methodology for a number of techniques, including DXA, BIA, ultrasound, underwater weighing, ADP, total body water, multicomponent models, anthropometry (including skinfolds and circumferences), and BMI. The text uncovers the sources of error inherent in each measurement technique, and it identifies populations to whom these techniques can be applied with accuracy. Researchers and clinicians alike will benefit from descriptions of methods for use in both laboratory and field settings, protocols for the standardization of each method, and advantages and limitations for each method. The text thoroughly examines the health implications of body composition by looking at the relationships between chronic disease and total body fat, fat distribution, muscle mass, and bone density. It also facilitates the reader’s ability to assess changes in body composition over time and to understand special considerations in assessing body composition in athletes, children, older adults, the overweight population, and clinical populations. ACSM’s Body Composition Assessment is supplemented with a web resource containing audio-narrated PowerPoint slides to support a deep understanding of the content. The slides walk readers through key points and assessments in each chapter, and select photos and tables from the book are included to facilitate learning and retention. ACSM’s Body Composition Assessment will help alleviate errors in body composition assessment, making it an ideal reference for practicing fitness, health, and medical professionals; nutrition specialists; and exercise physiologists.

Available in PDF, EPUB and Kindle. Book excerpt: Size at birth and size and body composition at two years are predictive of long term metabolic outcomes. There are many different methods of assessing body composition, but these may be affected by ethnicity and reliability in two-year-olds has not been reported. Aims To compare size and body composition at two years in children of different ethnic groups and with different risk factors for hypoglycaemia at birth. To compare different methods of assessing body composition in young children. Methods Prospective follow-up of a cohort of children born with risk factors for neonatal hypoglycaemia (infants of diabetics, large or small at birth, or late preterm). At 2 years’ corrected age children were measured (weight, height, head circumference, abdominal and mid arm circumferences, triceps and subscapular skin fold thickness) and fat and fat-free mass estimated using bioelectrical impedance. Results A total of 300 children were assessed. Pacific children (n = 50) were larger and had greater body mass index (BMI) than other groups and also had higher fat-free mass for their BMI. Indian children (n = 37) had lower BMI and lower fat-free mass for their BMI, but fat mass was similar in all groups. Children in the small (n = 39) and preterm groups (n = 23) were of similar weight at birth, but at 2 years only those born small remained smaller. Children who were born small gained more lean mass and those born preterm gained more fat mass per unit increase in weight zscore between birth and two years. Correlation between the different methods of measuring body composition was poor, with fat mass percentage calculated from bioelectrical impedance being the most variable and showing the least correlation with other methods used in this study. Conclusion In this multi-ethnic cohort of New Zealand children, BMI at two was affected by ethnicity and perinatal risk factors, and was not a good indicator of body composition. Current methods of measuring body composition are not consistent or able to be obtained reliably in two-year-old children, and therefore have important limitations when used in research settings.

Download or read book Anthropometric Standards written by A. Roberto Frisancho and published by . This book was released on 2008 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: ". . . a useful and long-needed stand-alone clinical manual for nutritional assessment." ---American Journal of Physical Anthropology This is a revised and updated 2nd edition of Anthropometric Standards for the Assessment of Growth and Nutritional Status. The data is based on the most recent available from the government (2003), and reflects the demographic change in the U.S. The easy-to-use tables and graphs have been expanded from age 2 months to 90 years. Designed for physicians, medical students, pediatricians, family doctors, and nutritionists interested in the physical growth and development of adults and children, this book presents in one volume the compilation of the largest database of material on anthropometric standards from National Health Examination surveys. Because the information is presented in tabular and graphic form, medical investigators can easily compare and interpret their findings with the collection of normative values. No other book is as inclusive, as soundly based, or as potentially useful to people interested in nutrition, cardiovascular diseases, anthropometry, and epidemiology. This is a resource that no health care worker should be without. A compact disc (CD) is included with the book for interactive evaluation of nutritional anthropometry in order to determine an individual's percentile and Z-score of the measurements of body size and composition. The CD is divided into three sections: Section 1 is based on anthropometric data source derived from the 3rd National Health and Nutrition Examination Survey conducted during 1994-98. Section 2 is based on weight, height, and body-mass index information developed by the Centers for Disease Control (CDC) for children ages 2 months to 20 years. Section 3 contains information developed by the World Health Organization (WHO) on weight and length for children ranging in age from birth to 5 years. All three sections are presented in Excel spreadsheets formatted to allow calculation of age- and sex-specific Z-scores and percentiles directly without the need for additional computer programs or software. A. Roberto Frisancho is Thurnau Professor of Anthropology at University of Michigan.

Download or read book BODY COMPOSITION ASSESSMENT BY A BIOIMPEDANCE SCALE IS A BETTER ROUTINE MEASUREMENT OF BODY ADIPOSITY THAN BODY MASS INDEX written by Avivit Brener and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background and aims: Body mass index (BMI) is a standard measure of weight in children and adolescents, but it is not a direct measure of adiposity. It may overestimate fatness in children who have high muscle mass or underestimate fatness in children who have low muscle mass. In 2018, our Endocrinology Unit implemented a bioimpedance scale as part of the routine anthropometric growth and nutrition assessment. We aimed to investigate the association between BMI and body composition. Methods: Cross-sectional study. Patients 5-19 years of age were assessed using the Tanita Body-Composition Analyzer (Tanita MC-780 MA) (Figure 1). Outcome measures: BMI-SDS, body-fat (BF%) categories (healthy/obese/over-fat/under-fat).Results: Our cohort was comprised of 318 patients (47% males), mean age 12.8u00b13.4 years. BMI overestimated and underestimated body adiposity in boys and girls (0.6% and 43%; 1.2% and 30.3%, respectively). Distribution of weight-status differed between BMI-SDS and BF% (in boys: 69% healthy, 11.5% obese, 12.8% overweight, 6.7% underweight versus 49.3% healthy, 33.8% obese, 15.5% over-fat, 1.4% under-fat, 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 at the University of Toronto, Ontario, Canada, June 20 - 23, 1989. The purpose of this conference was to report on advances in techniques for the in vivo measurement of body composition and to present recent data on normal body composition and changes during disease. This conference was the most recent of several meetings on body composition studies, and follows two successful such meetings, one at Brookhaven National Laboratory in 1986, and at Edinburgh in 1988. The large number of excellent research papers and posters presented at these conferences demonstrates the rapid growth of the field and the broad interest in the subject of in vivo body composition studies. The proceedings of the Brookhaven meeting "In Vivo Body Composition Studies", is published by The Institute of Physical Sciences in Medicine, London. Both the Brookhaven and the current Toronto meeting emphasized the clinical applications, together with the techniques employed. The Edinburgh meeting placed more emphasis on the methodological problems and design of instrumentation. Because of the number of papers presented at the meeting it was necessary to ask the authors from the same institution to combine their presentations into a single paper where appropriate. The editors wish to thank the authors for their cooperation and for graciously accepting the minor revisions made to each manuscript.
