Resumen
Whole-body bioelectrical impedance analysis (BIA) was evaluated for its reliability and accuracy in estimating body composition in children and youth. The established electrical principle for estimating volume in a geometrical system from conductor-length('2) divided by impedance is the basis for the use of this method in humans. The hypothesis that body-height('2) divided by the resistance component of impedance (resistance index) can be used to estimate total body water (TBW), fat free body (FFB), and percent fat (%FAT) was tested.

Resumen
Bioelectrical impedance analysis, (BIA), is a method of body composition analysis first investigated in 1962 which has recently received much attention by a number of research groups. The reasons for this recent interest are its advantages, (viz: inexpensive, non-invasive and portable) and also the increasing interest in the diagnostic value of body composition analysis. The concept utilised by BIA to predict body water volumes is the proportional relationship for a simple cylindrical conductor, (volume oc length2/resistance), which allows the volume to be predicted from the measured resistan

The reliable measurement of growth and condition is vital for effective fisheries assessments. Biologists have long attempted to estimate condition for their assessments, but a reliable method to nonlethally estimate body composition is lacking. Proximate analysis is the most dependable and accurate method for estimating internal composition, but it is lethal, time consuming, and expensive. Recent research has shown bioelectrical impedance analysis (BIA) to be an effective method for estimating proximate composition in some fishes.

Intermittent energy restriction has become a popular method for the management of obesity. It is however a very old concept, although not always used specifically for weight loss, a good example being the Ramadan fast. While the Ramadan fast has been shown to lead to weight loss, the assessment of body composition changes may be another important consideration. Chapter 2 therefore assesses the effect of the Ramadan fast on body composition via a systematic review and meta-analysis. This showed that the Ramadan fast caused a decrease in all parameters of body composition. Subgroup analyses show

Resumen
Bioelectrical impedance analysis (BIA) is a non-invasive technique widely used in body composition assessment. Nevertheless, its accuracy is compromised because of its reliance on regression equations and assumptions that are not frequently met. The bioelectrical impedance vector analysis (BIVA or "classic BIVA") emerged as an alternative technique to overcome conventional BIA limitations, founding its main strength on the use of raw impedance variables. BIVA is nowadays a widely used technique in medicine for the assessment of hydration and nutritional status in different clinical conditions.

Obesity is a major public health problem in both developed and developing countries. The body mass index (BMI) is the most common index used to define obesity. The universal application of the same BMI classification across different ethnic groups is being challenged due to the inability of the index to differentiate fat mass (FM) and fat�]free mass (FFM) and the recognized ethnic differences in body composition. A better understanding of the body composition of Asian children from different backgrounds would help to better understand the obesity�]related health risks of people in this region.

Obesity is caused by positive energy intake, poor exercise habits, environmental factors, food habits and stress etc. It is also known that hormones influence the incidence of obesity

Resumen
O período pós-parto pode ser considerado a fase em que a mulher está exposta a retenção de massa corporal (MC) e desenvolvimento da obesidade. Na maioria das situações valorizam-se mais a perda de MC e pouco se conhece a respeito dos componentes que estão sendo mobilizados. Desta forma, há interesse de se validar técnicas acessíveis, como a impedância bioelétrica (BIA), que possam ser aplicadas no acompanhamento nutricional destas mulheres. O presente estudo teve como objetivo validar diferentes modelos de impedância bioelétrica (BIA) para a determinação da composição corporal em mulheres pós-

Resumen
Des spécificités de la technologie SOI partiellement désertée (PD-SOI), comme son gain en vitesse, et l'isolation diélectrique des transistors, sont intéressantes pour la conception d'interfaces entrées/sorties. Toutefois, l'emploi de cette technologie conduit à des phénomènes indésirables tels que l'effet d'histoire, une consommation statique accrue et l'effet d'auto-échauffement. Dans ce travail, une analyse de ces effets a été menée. L'influence de l'auto-échauffement s'est révélée négligeable. Un schéma électrique employant un mécanisme de polarisation active a été proposé afin de supprime

Resumen
There is an increase in the prevalence of obesity among people with schizophrenia thought to be due in part to the weight enhancing side-effects of medications commonly used to treat the symptoms of schizophrenia. Despite the deleterious health effects associated with obesity and its impact on quality of life and medication compliance, little is known about body composition and energy expenditure in this clinical group. The primary purpose of this thesis was to enhance understanding of body composition and energy expenditure, particularly resting energy expenditure in men with schizophrenia wh
